Description

SYSTEMS AND METHODS FOR BUILDING WATER-LEAK DETECTION AND
ALERT
BACKGROUND
Technical Field Aspects and embodiments disclosed herein relate generally to environmental monitoring and response systems and methods for enhancing operations management capabilities.
Discussion of Related Art Currently, most monitoring solutions used in construction environments are manual.
Monitoring for conditions of concern is typically performed either by observation or by use of handheld sensors with minimal logging features outside of manually recording the data. The use of the measurement methods is sporadic and the repeatability of these measurements cannot be confirmed. This data also holds little to no value to insurance companies in the case of an accident claim. For periods of time, for example, after work hours, a site may be left without any method of data measurement or monitoring. Wireless, stationary unit systems exist to measure specific variables, for example, dust particulates and dangerous gasses;
however, these systems are not integrated into a seamless solution for site monitoring. Often, these systems do not provide real-time or near real-time data and do not offer immediate or near immediate alerts of ongoing conditions.
Construction companies have an interest in monitoring the environmental conditions of their worksite to reduce the occurrence of undesired conditions that are costly and lead to delays in the construction work timeline. For this reason, construction companies are moving to digitize the job site by integrating new technologies into their work routines. Some construction company personnel now use mobile devices, for example, handheld tablets or smartphones, allowing site drawing updates to be pushed to the hands of the user in real-time. This monitoring solution is designed to integrate into the currently existing use of digital solutions already being implemented on a site.
Constructions companies are further interested in streamlining compliance with regulatory agencies, maximizing attractiveness to employees and labor groups, and minimizing insurance premiums by demonstrating a greater capacity for risk mitigation.
The fragmented and ad hoc nature of current monitoring solutions does not provide sufficient benefits to construction companies in these areas and stands to be improved.
There remains a need for an improved and more reliable system for monitoring and providing risk management of a remote site, for example, a construction site.
SUMMARY
Aspects of the disclosure include a water-leak-detection and -monitoring system for a building, the system comprising a memory, a communication interface configured to be communicatively coupled to at least one water-flow sensor coupled to a water pipe in the building, at least one of a humidity sensor, a temperature sensor, or a liquid-water sensor configured to sense information indicative of a presence of water in a first area in the building in which the water pipe is located, and an analytical engine in communication with a base unit, the memory, the communication interface, and the at least one of the humidity sensor, the temperature sensor, or the liquid-water sensor, the analytical engine being configured to determine whether a water leak is present in the building based on analysis of water-flow-rate data from the at least one water-flow sensor, and determine, responsive to determining that the water leak is present, if the water leak is occurring in the first area of the building based on the information indicative of the presence of water in the first area in the building in which the water pipe is located.
In various examples, the communication interface is configured to communicate with a water-flow-control valve disposed on the water pipe, the analytical engine being further configured to control the water-flow-control valve to turn off water flow through the water pipe responsive to the determination that the water leak is present. In some examples, the analytical engine is a cloud-based system configured to control the water-flow-control valve via a signal sent to the base unit and sent from the base unit to the water-flow-control valve. In at least one example, the water pipe includes multiple water-flow-control valves and the analytical engine is further configured to select a water-flow-control valve upstream of and closest to the first area of the building to control to turn off water flow through the water pipe.
In various examples, the base unit includes the at least one of the humidity sensor, the temperature sensor, or the liquid-water sensor, and the system further comprises a second base unit including one or more of a second humidity sensor, a second temperature sensor, or a second

2 liquid-water sensor disposed in a second area in the building in which the water pipe is present, the analytical engine further being in communication with the second base unit and, responsive to a determination that the water leak is present, the analysis engine configured to determine if the water leak is occurring in the second area of the building based on analysis of data from one or more of the second humidity sensor, the second temperature sensor, or the second liquid-water sensor. In some examples, the analytical engine is further configured to select a water-flow-control valve upstream of and closest to the second area of the building to control to turn off water flow through the water pipe, responsive to a determination the water leak is occurring in the second area of the building.
In at least one example, the base unit includes an AC-power interface and a battery backup configured to activate if power through the AC-power interface is suspended, the base unit configured to communicate activation of the battery backup to an external monitoring platform. In various examples, the analytical engine is included in a cloud-based software program that collects data from the base unit and any other base units in the system and that includes a user interface providing for users to view real-time and historical data collected by the base units and the at least one water-flow sensor. In some examples, the user interface is further configured to receive and transmit commands to the analytical engine from a user to control one or more water-flow-control valves disposed on the water pipe. In at least one example, the user interface is further configured to receive and transmit commands to the analytical engine from a user to override water-flow-control-valve control decisions automatically generated by the analytical engine.
According to various examples of the disclosure, a method of detecting and monitoring water leaks includes receiving water-flow-rate data from at least one water-flow-rate sensor coupled to a water pipe in a first area of a building, receiving, from at least one of a humidity sensor, a temperature sensor, or a liquid-water sensor, information indicative of a presence of water in the first area of the building, determining that a water leak is present in the building based on the water-flow-rate data from the at least one water-flow sensor, and determining, responsive to determining that the water leak is present, whether the water leak is occurring in the first area of the building based on the information indicative of the presence of water in the first area in the building in which the water pipe is located.

3 In various examples, the method includes controlling a water-flow-control valve coupled to the water pipe to turn off water flow through the water pipe responsive to the determination that the water leak is present. In some examples, controlling the water-flow-control valve includes sending a cloud-based signal from a cloud-based system to a base unit including the at least one of the humidity sensor, the temperature sensor, or the liquid-water sensor, and sending, by the base unit responsive to receiving the cloud-based signal, a control signal to the water-flow-control valve to turn off water flow through the water pipe. In at least one example, the water pipe includes multiple water-flow-control valves, and the method further comprises selecting a water-flow-control valve upstream of and closest to the first area of the building to control to turn off water flow through the water pipe.
In various examples, the method includes receiving, from at least one of a second humidity sensor, a second temperature sensor, or a second liquid-water sensor, second information indicative of a presence of water in a second area of the building, determining that a second water leak is present in the building based on second water-flow-rate data from the at least one water-flow sensor, and determining, responsive to a determination that the second water leak is present, whether the second water leak is occurring in the second area of the building based on analysis of the second information indicative of the presence of water in the second area of the building. In some examples, the method includes selecting a water-flow-control valve upstream of and closest to the second area of the building to control to turn off water flow through the water pipe, responsive to a determination the water leak is occurring in the second area of the building. In at least one example, the method includes receiving commands from a user to override water-flow-control-valve control decisions that are generated automatically.
According to various examples, a non-transitory computer-readable medium storing thereon sequences of computer-executable instructions for detecting and monitoring water leaks is provided, the sequences of computer-executable instructions including instructions that instruct at least one processor to receive water-flow-rate data from at least one water-flow-rate sensor coupled to a water pipe in a first area of a building, receive, from at least one of a humidity sensor, a temperature sensor, or a liquid-water sensor, information indicative of a presence of water in the first area of the building, determine that a water leak is present in the building based on the water-flow-rate data from the at least one water-flow sensor, and

4 determine, responsive to determining that the water leak is present, whether the water leak is occurring in the first area of the building based on the information indicative of the presence of water in the first area in the building in which the water pipe is located.
In various examples, the sequences of computer-executable instructions include instructions that further instruct at least one processor to control a water-flow-control valve coupled to the water pipe to turn off water flow through the water pipe responsive to the determination that the water leak is present. In at least one example, in controlling the water-flow-control valve, the sequences of computer-executable instructions include instructions that further instruct at least one processor to send a cloud-based signal from a cloud-based system to a base unit including the at least one of the humidity sensor, the temperature sensor, or the liquid-water sensor such that the base unit sends, responsive to receiving the cloud-based signal, a control signal to the water-flow-control valve to turn off water flow through the water pipe.

DETAILED DESCRIPTION
In accordance with various aspects and embodiments, there is provided a monitoring solution having an intelligent communication interface. The monitoring solution may provide real-time, continuous measurements of water flow and environmental conditions to a nearby or

7

8 remote location external to the monitoring equipment. A plurality of sensors may measure water flow and environmental conditions. Measured data may be converted to digital data and transmitted wirelessly or through a wired connection to a software platform capable of mitigating undesirable conditions, for example, water leaks, and capable of generating quantifiable metrics a user can act upon. Users may use this data to track, trend, and predict potential points of liability at a desired location using the monitoring solution. Locations for use of this system include but are not limited to residences, office buildings, construction sites, oil rigs or refineries, mining sites, industrial settings, and renovation work sites. For ease of description, these locations are collectively referred to herein as "buildings."
Aspects and embodiments disclosed herein relate to an environmental monitoring and risk mitigation system for a structure or a location of industrial activity.
The system can generate alerts to inform a user of existing, suspected, or possible conditions, events, and/or damage. The system can generate warnings to assist the user in the prevention of site damage and/or to adhere to assumed or specified requirements. Data from different sensors can be paired together to provide more accurate readings and/or more actionable data than possible by using sensors individually. In some embodiments, groups of data each representing different parameters may be similarly combined to provide more accurate readings and/or more actionable data even if one or more groups of data is collected from the same sensor or sensor group.
Analysis performed by a software platform included in the system can recognize trends in sensor data to produce .. predictions regarding future event occurrences. Analysis performed by the software platform can recognize trends to create suggestions regarding building performance, maintenance, climate control, air quality, and/or construction techniques. The system can aid the user in making quick, informed decisions and/or reduce liability. Report generation will display sourced data to highlight patterns or trends identified over time with use.
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that, throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
FIG. lA is a diagram of a monitoring system in accordance with an illustrative aspect of the present invention. Portable base unit(s) 01 communicate information, for example, sensor .. conditions and/or alarm conditions, via wireless communications 02, 03 with server(s) 04 and can be wirelessly re-programmed using over-the-air programming methods initiated by the server(s) 04. The wireless communication used may illustratively be low-power wide-area network (LPWAN) 33 (as shown in FIG. 2), satellite 02, and/or cellular 03. It should be understood that while the following description references satellite 02, cellular 03, and LPWAN
33, other wireless communication protocols, frequencies, or frequency bands may also or alternatively be used, for example, low frequency (LF), very high frequency (VHF), ultra-high frequency (UHF), or 802.11 (and similar communications). A user can interface with one or more servers 04 via a phone 05 or the internet 06 to manage the monitoring system (e.g., configure it and/or to receive information from the monitoring system, for example, sensor conditions, stored data, warnings, alarms, trends, predictions, system health or means to improve site efficiency). The one or more servers 04 will contain and/or execute various software packages that comprise much of the "backend" functionality of the present system.
FIG. 1B depicts one embodiment of external sensor modules 23 connected via a mesh network to a base unit 01. A plurality of external sensor modules 23 and/or external sensor arrays 424 (FIG. 2) may communicate with one or more base unit(s) 01 using LPWAN, Bluetooth, ZigBee, LF, VHF, UHF, 802.11, Wi-Fi, satellite, cellular network, or other wireless or wired communication methods or protocols. External sensor modules 23 and/or external sensor arrays 424 may be located in close proximity to base unit(s) 01 and contain specific sensors or combination of sensors intended to monitor for specific conditions.
Responsive to analysis of input data sourced from base unit(s) 01, or due to input data generated by user via a phone 05 or internet 06 interface, one or more software platforms each running on one or more servers 04 may wirelessly communicate a command to one or more base unit(s) 01 to perform an action. Actions may be performed by base unit(s) 01 or by external sensor unit(s) 23 and/or external sensor arrays 424. Certain base unit(s) 01 or external sensor unit(s) 23 and/or external sensor arrays 424 may be hard wired or wirelessly connected to one or more other systems within the site (e.g., an HVAC system, window fans, temporary heating solutions, humidifiers, dehumidifiers, negative air pressure solutions, machinery, tools, jackhammers, fire sprinkler systems, etc.) and may have the capability of regulating and/or controlling the one or more other systems. Actions generated or performed by the software platform, base unit(s) 01, and external sensor unit(s) 23 and/or external sensor arrays 424 may result in the prevention or mitigation of damages to the site and on-site equipment, improvement

9 of safety of on-site personnel, improvement of contractor logistics, reduction of timeline, or other improved efficiencies.
In some embodiments, the system may determine or be instructed to perform an action.
For example, the system may detect an elevated level of moisture in one or more areas, zones, and/or sub-zones of a site being monitored. In some embodiments, the system may be configured to perform a first action or set of actions, for example, adjusting the position of one or more valves in one or more pipes to restrict the flow of water to said areas, zones, and/or sub-zones possessing the elevated level of moisture. In certain embodiments, the system may first check that this behavior will not have undesired consequences on one or more additional actions being performed or having the potential to be performed. For example, before adjusting the position of the one or more valves, the system may first check to make sure that a fire has not been detected in one or more of said areas, zones, and/or sub-zones, since altering the flow of water to one or more of those locations may allow the fire to spread and cause more damage than an event associated with the elevated level of moisture.
In some embodiments, the system may be configured to instruct workers or control machinery to suspend and/or initiate one or more actions in one or more zones or locations responsive to the analysis of input data. For example, the system may deactivate one or more sprinkler heads not proximate to a detected fire to avoid excess water damage to the site. In another example, the system may reschedule time sensitive activity such as painting or pouring concrete responsive to detecting that the previous coat or layer is not sufficiently dry or that ambient conditions are not favorable.
For example, base unit(s) 01 or external sensor(s) 23 and/or external sensor arrays 424 may be connected to electrically motorized zone valve(s), which are connected in-line with the site's water supply. A software platform running on server 04 or controller 18 (FIG. 2) within .. base unit 01 may generate an alert and/or warning upon analysis of flow meter data and subsequently wirelessly communicate a command to base unit 01 to perform the action of activating the electrically motorized zone valve to turn ON or OFF the flow of water or restrict maximum flow allowing for prevention and mitigation of water damage.
A software platform running on server 04, or controller 18 within base unit 01, may generate an alert and/or warning upon analysis of temperature sensor(s) data and humidity sensor(s) data and subsequently wirelessly communicate a command to base unit 01 to perform the action of activating site's HVAC system, site temporary heating/cooling system, and/or humidifier/dehumidifier systems which allows for prevention and mitigation of high humidity damage, low temperature damage, mold damage, or undesirable worker conditions.
Through the use of a built-in microphone on or in the base units 01, acoustic performance of an enclosed area can be measured to show how noise flows through a site.
When a noise occurs, sound waves will propagate through a room and fixed surfaces, outward to any adjacent, open spaces. With a network of base units 01 throughout a site, the path that noise travels can be mapped by focusing on the amplitude of the noise measurements and the slight time delay that occurs as noise travels. Areas where noise penetrates with a higher amplitude relative to other areas may indicate weak acoustic locations due to flanking noise, HVAC
ductwork, or other sources of acoustic weak points. Noise information may further be used for security purposes such detecting and/or tracking unauthorized activity, for example, detecting the presence of an intruder at the site and tracking their movements throughout.
Base unit(s) 01 may also be outfitted with one or more additional internal sensors 20, internal sensor arrays 24, and/or external sensor arrays 424 as shown in FIG.
2. For example, a software platform running on server 04, or controller 18 within base unit 01 may combine data from UV sensors and/or light sensors with that from temperature 11 and/or humidity 10 sensors to monitor the amount of daylight a space in a site receives. Fluctuations in environmental parameters in a room may be indicative of how sunlight or refracted light has an effect on the temperature, humidity, and environmental conditions of a room. By utilizing temperature and humidity measurements, the indoor dew point can be calculated and monitored.
Dew point metrics may be used for monitoring air quality and determining if water will condense on surfaces.
In some embodiments, an internal sensor 20, additional external sensor 23, and/or internal or external sensor array 24, 424 may include one or more infrared (IR) sensors and/or passive infrared (PIR) sensors. IR and PIR uses include, for example, detection of heat signatures for occupancy monitoring, and detection of heat signatures for fire detection and classification.
Data collected from base unit(s) 01 can also be utilized during environmental certification, for example, LEED or BREEAM. Information, for example, greenhouse gas emissions during construction can be monitored using CO, CO2, or methane sensors, or other applicable internal sensors 20, external sensor modules 23, and/or internal or external sensor arrays 24, 424. Minimum indoor air quality performance may be continually monitored using dust particulate sensors, smoke detecting sensors, and/or gas sensors.
Criteria focusing on water metering, whether indoor, outdoor, or building level can be subsequently handled through the use of electrically motorized zone valves and flow metering devices. Acoustic performance and daylight/interior lighting monitoring is possible with onboard sensors previously highlighted.
Base unit(s) 01 or external sensor(s) 23 and/or external sensor arrays 424 may be connected to air pressure regulator(s). A software platform running on server 04, or controller 18 within base unit 01, may generate command(s) upon analysis of pressure sensor data and subsequently wirelessly (or over a wired connection) communicate a command to base unit 01 to perform the action of regulating the activity of the air pressure regulator allowing for adherence to negative air pressure regulations.
Base unit(s) 01 or external sensor(s) 23 and/or external sensor arrays 424 may be connected to on-site machinery and tools including but not limited to jackhammer(s) and pile driver(s) and/or sources of power or pneumatic pressure for same. A software platform running on server 04, or controller 18 within base unit 01, may generate an alert and/or warning upon analysis of accelerometer sensor or vibration sensor data indicating the presence of vibrations at undesirable frequencies or amplitudes and subsequently wirelessly (or over a wired connection) communicate a command to base unit 01 to perform the action of de-activating or changing a mode of operation of the on-site machinery and/or tools allowing for prevention and mitigation of structural damage, foundation cracking, and the like.
Base unit(s) 01 or external sensor(s) 23 and/or external sensor arrays 424 may be connected to a localized water sprinkler system that may be comprised of localized electrically motorized valve(s) or switch(es) which control the flow of water on a room by room basis, regional basis within a site, or sprinkler head basis. A software platform running on server 04, or controller 18 within base unit 01, may generate an alert and/or warning upon analysis of temperature sensor, smoke sensor, dust particulate sensor, oxygen sensor, CO2 sensor, PIR
sensor, humidity sensor, volatile organic compound (VOC) sensor, pressure sensor, acoustic sensor, and/or accelerometer data indicating the presence or possibility of a fire and subsequently wirelessly (or over a wired connection) communicate a command to base unit 01 to perform the action of activating the electrically motorized valve or switch to turn ON or OFF the localized sprinkler system allowing for prevention and mitigation of fire damage and subsequent water damage. By controlling which sprinklers are activated, water dispersal and resulting water damage may be contained. System connection to the water sprinkler system may be embodied as an external sensor unit 23 which replaces an existing sprinkler head, or is inserted in-line with the sprinkler system between the piping and the sprinkler head.
In some embodiments, an external sensor 23, internal sensor 20, internal sensor array 24, and/or external sensor array 424 may comprise a power sensor or power meter connected to one or more power outlets disposed at the site being monitored. The power sensor may be in wireless or wired communication with one or more base units 01 or directly to server 04 and configured to measure an amount of power drawn from the one or more outlets being monitored.
In certain embodiments, the power sensor may possess one or more power ports allowing power to be drawn from the site power outlets and relayed through the power meter before being provided to a connected load. By measuring the amount of power drawn from the one or more power outlets, the power sensor 20, 23 or array of power sensors 24, 424 can detect usage and various power events, for example, a power surge or outage. In further embodiments, power sensor may be configured to provide surge protection responsive to a detected power surge or otherwise limit usage based on factors such as received power pricing information.
In certain embodiments, a base unit 01, external sensor 23, external sensor array 424, external peripheral 30, and/or other connected site component may be communicatively coupled to one or more gateways and/or routers 32. A gateway and/or router 32 may function as an intermediary allowing one or two-way communication between the connected component(s) and a communications service or module such as a satellite 02, cellular tower 03, server 04, additional gateway and/or router 32, and/or another communications service or module. In other embodiments, a base unit 01, external sensor 23, external sensor array 424, external peripheral 30, and/or other connected site component may be in direct communication with a communications service or module such as a satellite 02, cellular tower 03, server 04, and/or another communications service or module without the use of a gateway as a communications intermediary. In some embodiments, one or more wireless repeaters may be positioned proximate to the one or more gateways 32 to extend the signal range of each of the one or more gateways. Server 04 may further be coupled to one or more application programming interfaces (APIs) 31 for building and/or managing the software executing on server 04.

FIG. 2 is a block diagram of one embodiment of a base unit 01. Base unit 01 includes one or more controllers 18 each coupled to one or more wired or wireless communication modules, for example, an LPWAN module 33, a cellular module 16, Wi-Fi module 17, satellite module, or any combination thereof, and a plurality of sensors including but not limited to one or more of a microphone 07, dust particulate sensor 08, vibration sensor 09, humidity sensor 10, temperature sensor 11, strain sensor 12, and smoke detector 13. Other types of internal sensors 20 or internal sensor arrays 24 may be similarly installed in a base unit 01 and may include water sensors, light sensors, radio frequency (RF) sensors, CO2 sensors, CO sensors, oxygen sensors, hydrogen sulfide (H2S) sensors, methane sensors, gyroscopic sensors, accelerometers, wind sensors, barometric sensors, infrared (IR) sensors, passive infrared (PIR) sensors, VOC sensors, a compass, photodiode sensors, and/or magnetic sensors. Any combination of internal sensors disclosed herein may also be installed as a group or array of sensors 24 within said base unit 01 or outside of said base unit as an external sensor array 424.
One or more external sensors 23 and/or external sensor arrays 424 that are not included in 15 the standard base unit can be added as external modules, either through a wireless or wired connection, to measure additional conditions or events of interest on a per application basis.
External sensors 23 and/or external sensor arrays 424 can comprise any of the internal sensor types 07-13, 20 and/or internal sensor array types 24 discussed herein and/or known to those in the art. For example, base unit sensors may include temperature sensors, humidity sensors, and 20 dust particulate sensors. Carbon dioxide (CO2), carbon monoxide (CO), and oxygen concentrations and levels may be of interest to monitor in a confined space on a job site, but not on the entire site. CO2, CO, and oxygen sensors may thus be added as additional sensors in the form of a modular plugin to standard base units placed within the confined space. Similarly, any external sensor types 24 or external sensor array types 424 disclosed herein may similarly be configured to be internal sensors 20 or internal sensor arrays 24, respectively. Any combination of internal sensors 20 and/or external sensors 23 of the present disclosure may comprise an internal and/or external sensor array 24, 424.
Wired connections may provide for communications and power to the internal sensors 20, external sensor(s) 23, and/or sensor arrays 24, 424. Internal sensor(s) 20 can include other types of sensors, for example, water, light, radio frequency (RF), CO2, CO, oxygen, hydrogen sulfide (H2S), methane, gyroscopic, accelerometer, strain, wind, and/or barometric sensors or any of the sensor types mentioned herein with respect to both internal and external sensors.
A cellular module 16 may be coupled to cellular antenna 14, a Wi-Fi module 17 may be coupled to Wi-Fi antenna 15, and an LPWAN module 33 may be coupled to LPWAN
antenna 34. In some embodiments, one or more additional communications modules 35 and associated antennas 36 may additionally be coupled to at least one of the one or more controllers 18 for providing one or two-way communications with an external client or service. In various embodiments the base unit may comprise any or all of the preceding communication modules depending on the desired configuration. In an illustrative aspect, battery 19 is a lithium ion or lithium polymer battery. Base unit 01 can be powered either by battery 19 and/or by a hard-wired connection to an external power supply 22. This external power supply can be a separate battery pack or a wall outlet to allow continuous power supply.
It should be understood that sensors 07, 08, 09, 10, 11, 12, 13, and 20 may be any sensor suitable for detecting the condition that the sensor is to sense. Sensors may also be used in combination to generate new or more accurate information. For example, the temperature sensor 11 may be paired with the smoke detector 13, humidity sensor 10, photodiode sensor, and PIR
sensor to better detect conditions indicative of fire. Temperature sensor 11 may be paired with humidity sensor 10, photodiode sensor, and PIR sensor to better detect mold growth conditions or conditions indicative of water leaks. A photodiode sensor may be paired with a humidity sensor, UV sensor, VOC sensor, and/or a temperature sensor to better detect undesirable worker conditions. A photodiode sensor may be paired with a noise sensor to better detect a site intruder or intruders. A photodiode sensor may be paired with a humidity sensor and/or a temperature sensor to better detect the flashing and/or spreading of a fire. An infrared sensor, either alone or in combination with another sensor, may better predict a type of fire, for example, differentiating between a welding arc fire versus a smoldering fire.
One or more controllers 18 obtains input data regarding sensed conditions or parameters from sensors 07, 08, 09, 10, 11, 12, 13, and 20 and sends a message via wireless communication using cellular module 16, Wi-Fi module 17, or LPWAN module 33 (or a wired connection) to server 04 containing data indicative of the conditions or parameters sensed by one or more of the sensors. Controller 18 is configurable, via wireless programming, to set which sensors 07, 08, 09, 10, 11, 12, 13, and 20 are active and how frequently data regarding the sensed conditions or parameters of each sensor are transmitted to server 04. Server 04 can configure controller 18 via wired or wireless communication to set the sensor settings and thresholds as well as frequency, time, and contents of controller 18 messages. For example, controller 18 may send data regarding the sensed conditions or parameters of sensors 07, 08, and 09 at a different frequency .. than that of sensors 10, 11, 12, 13, and 20 as dictated by server 04.
Controller 18 can be configured to generate alerts and warnings, as well as to send data regarding the sensed conditions or parameters of one or more of the sensors at a set frequency rate irrelevant of the sensed conditions or parameters. Alternatively, controller 18 can be configured to send data regarding the sensed conditions or parameters of one or more of the sensors only upon the sensed conditions or parameters being indicative of a possible event of concern. A
controller 18 may also store data and/or instructions in one or more connected sources of non-volatile memory 39 and/or volatile memory 40, for example, random access memory (RAM).
The system or a controller 18 may instruct one or more components of one or more base units to enter various modes of operation to make the system operate more efficiently. In various embodiments, the system or controller 18 may keep one or more sensor types in an OFF state or low power mode by default and only operate less energy or resource intensive sensors regularly.
When readings from the one or more less energy or resource intensive sensors indicate a possible event or preliminary event, the system or controller 18 may permanently, temporarily, or intermittently activate or change the operating mode of one or more of the sensors in an off state .. or low power mode to gather additional data regarding the event or preliminary event. For example, the system may keep one or more infrared sensors in an OFF state and one or more additional sensors in an ON state, for example, a temperature sensor and/or a smoke sensor. If and when the one or more additional sensor readings indicate a spike in a temperature or presence of smoke, the system can activate the infrared sensor to read a temperature gradient and more accurately confirm a suspected event such as a fire.
Alerts and/or warnings may be generated by either the base unit controller 18 or the software platform running on server 04 when selected conditions exist. Select conditions may be detected through analysis of measurements of one or more individual sensors or sensor types.
Alerts and/or warnings generated due to analysis of temperature sensor 11 data may be caused by .. the temperature of a region within the location being outside of one or more selected temperature ranges, the temperature rising at a rate that could be deemed unsafe or indicative of a fire, or temperature dropping at a rate that is undesired. Alerts and/or warnings generated due to analysis of humidity sensor 10 data may be caused by the humidity of a region within the location being outside of a selected humidity range or the humidity being at a level that could cause damage to millwork or other materials.
Alerts and/or warnings generated due to analysis of dust particulate sensor 08 data may be caused by dust particulate levels of a region within the location being outside of one or more selected dust particulate ranges or dust particulate levels being in violation to OSHA or property owner protocols/requirements and/or any specifications made in contracts, agreements, or stipulations. Alerts and/or warnings generated due to analysis of any type of gas sensor (e.g.
CO2, CO, oxygen, H2S, methane, propane, VOCs, etc.) data may be caused by gas levels within a region of the location being outside of one or more selected gas level ranges, gas levels exceeding flammable or explosive levels or gas levels exceeding recommended levels for worker safety.
Alerts and/or warnings generated due to analysis of accelerometer or vibration sensor 09 data may be caused by vibration within a region of the location being outside of one or more selected vibration ranges, vibration that exceeds structural strength levels, vibration that exceeds foundation strength levels, vibration at frequencies at a building or material's resonant frequency, or vibration that exceeds customer imposed limits or that may be disruptive or dangerous to surrounding structures. Alerts and/or warnings generated due to analysis of strain sensor 12 data may be caused by strain exerted on an object or entity being outside of one or more selected strain ranges, strain levels which indicate the possibility of the existence or future occurrence of structural damage, strain levels which indicate the possibility of the existence or future occurrence of foundation or framework damage, or strain levels which indicate the possibility of the existence or future occurrence of roof failure or collapse.
Alerts and/or warnings generated due to analysis of fluid flow sensor data, sourced from flow sensors mounted on or in on-site piping, may be caused by flow levels being outside of one or more selected flow ranges, flow levels considered irregular based on past trends, flow being detected when no flow should exist and/or flow indicative of a water leak.
Alerts and/or warnings generated due to analysis of electrical power level data, electrical current data, electrical impedance data, and/or electrical voltage data may be caused by levels being outside of one or more selected ranges, levels considered irregular based on past trends, levels being detected when none should exist and/or levels indicative of a power surge or electrical fire event.
The software platform running on server 04 may also be able to raise alerts due to analysis of data generated by more than one type of sensor. Combining sensor data from several different types of sensors may provide for more accurate detection of certain conditions, or detection of conditions that is not possible by using one sensor individually.
One or more internal sensors 20, external sensors 23, and/or sensor arrays 24, 424 may be configured to detect weather data. For example, the one or more internal sensors 20, external sensors 23, and/or sensor arrays 24, 424 may include an ambient pressure sensor, humidity sensor, wind sensor, and/or other type or types of sensors known to those in the art for detecting weather phenomena. The one or more internal sensors 20, external sensors 23, and/or sensor arrays 24, 424 may be disposed on the exterior of the site(s) being monitored to more directly contact the environment outside of the site, such as an ambient weather environment.
Data generated by accelerometer(s) or vibration sensor(s) may be analyzed in conjunction with data generated by strain sensor(s) to monitor, detect, or predict structural foundation damage, including cracking or widening of existing cracks, or structural roof failure.
Data generated by accelerometer sensor(s) may be analyzed in conjunction with data generated by gyroscope sensor(s) and strain sensor(s) to more accurately monitor, detect, and/or predict building sway or vibration levels that may exceed structural safety levels as well as flexure of structural and support beams/members.
Data generated by temperature sensor(s) may be analyzed in conjunction with data generated by oxygen sensor(s), humidity sensor(s), smoke sensor(s), dust particulate sensor(s), IR sensors, PIR sensors, photodiode sensors, CO2 sensor(s), and/or CO
sensor(s) to more accurately monitor, detect, and/or predict conditions indicative of fire or the potential for fire.
Software system running on server 04 may track the spread of fire throughout a site and monitor, detect, and/or predict the direction of propagation of the fire as well as how fast the fire will spread using related sensor data (e.g., oxygen levels, temperature levels, and/or humidity levels).
A notification or other software system running on server 04 may provide this information to a third party such as a fire department to allow for a more efficient response to the fire.

Data generated by humidity sensor(s) may be analyzed in conjunction with data generated by temperature sensor(s), PIR sensors, and/or microphone(s) to more accurately monitor, detect, predict, and/or locate water leaks or running water.
Data generated by humidity sensor(s) may be analyzed in conjunction with data generated by temperature sensor(s), light sensor(s), IR sensors, PIR sensors, and/or ultraviolet (UV) sensor(s) to more accurately monitor, detect, and/or predict conditions which may support mold growth.
Data generated by temperature sensor(s) may be analyzed in conjunction with data generated by humidity sensor(s), microphone(s), light sensor(s), UV sensor(s), PIR sensors, oxygen sensor(s), and/or carbon dioxide sensor(s) to more accurately monitor, detect, and/or predict improper seals, leaks, cracks, holes, or related damage in the building envelope.
Data generated by microphone(s) may be analyzed in conjunction with data generated by accelerometer(s), vibration sensor(s), temperature sensor(s), IR sensors, PIR
sensors, photodiode sensors, and/or humidity sensor(s) to more accurately monitor, detect, and/or predict building security and building surveillance.
The server 04 can analyze and record the input data from a plurality of base units 01 for further analysis, for example, by comparing sensor input data throughout a larger region of a site or detecting trends in sensor input conditions between multiple regions of a site or between several sites, and can generate additional alerts, warnings, or reports that could not be possible based off of the data from an individual base unit 01. The server 04 can also source data to be used when performing analytics from other input methods or sources (e.g., sources on the internet, other APIs or software development kits (SDKs), and any partnering company's products).
Warnings, alerts, and reports generated the controller 18 or the server 04 can be used by the user to prevent and/or mitigate events that have the potential to damage the site or cause an unsafe environment. The user and other personnel on the location (e.g., construction site, oil rig or refinery, mining location, industrial site, and/or renovation site), or the personnel managing the location can have records of environmental factors and data for recourse on possible insurance claims, warranty claims, equipment failures, and/or damages to the job site.
In some embodiments, base units 01 may further comprise one or more transceivers 25 for communicating with an external device, for example, a worker's handset, cell phone, tablet, or other mobile electronic device. Transceiver 25 may be a low energy transceiver such as a Bluetooth module, ZigBee module, LPWAN module, or other low- or high-energy transceiver or transceivers known to those in the art. Transceiver 25 may be configured to locate, identify, or communicate with one or more external devices within its signal range.
In other embodiments, base units 01 may be connected to one or more external peripherals 30 including any manner of electronic, mechanical, or other device capable of being controlled by or communicating with the base unit. An external peripheral 30 may comprise an actuator or other non-sensor device (or array of actuators or other non-sensor devices) capable of performing an action to affect the site or environment proximate to said base unit 01 or peripheral 30. A peripheral 30 may be configured to toggle one or more devices between an ON
and an OFF state or control other aspects of operation. For example, a peripheral 30 may control the ON/OFF state or operating mode of one or more propane heaters, fans, lights, humidifiers, and/or other devices disposed in and around the site being monitored. An actuator or other non-sensor device (or array of actuators or other non-sensor devices) serving the function of a peripheral 30 as described herein may instead be disposed internally within the housing of the base unit.
In other embodiments, base units 01 may comprise one or more user interface (UI) elements 26 and/or physical buttons 27. UI 26 may be configured to display information relevant to the site or sites being monitored. UI 26 and/or physical button 27 may be further configured to trigger an action or omission in response to being pressed or otherwise activated by a user. For example, responsive to a user pressing physical button 27 or UI
element 26, the UI
26 and/or an external handset may display a map of the site or sites being monitored along with a location of the base unit and the worker location at that base unit, initiate a call for help, or signal an emergency at that location. A button 27 may, for example, be configured to perform a predetermined action when a user interacts with it in a certain manner. For example, holding down a particular button may trigger an alarm, whereas tapping the button may open a communications channel allowing the user to speak directly with security personnel.
In some embodiments, base units Olmay comprise one or more speakers 29 and/or intercoms 28. Base units in communication with one and other may therefore be configured to function as a distributed worker communication system using said speakers 29 and intercom 28.
The intercom system may also involve external handsets and devices also connected to the base unit. The speaker 29 may also be used to play alert sounds or relay other audible information to the site. The speaker 29 may also be used to locate individual devices upon user engagement with software platform.
In various embodiments, data received by or transmitted from sensors, base units, and/or the server may be encrypted using one or more data encryption methods. For example, data may be encrypted using block chain encryption, public key encryption, symmetric key encryption, and/or any combination of encryption methods know to those in the art. The encrypted data may be subsequently decrypted by the server 04, peripheral 30, other system component, and/or third-party device intended to decrypt the encrypted information.
In further embodiments, data received by or transmitted from sensors, base units, and/or the server may be associated with one or more pieces of metadata. For example, data received by or transmitted from sensors, base units, and/or the server may be time stamped.
In certain embodiments, a base unit may be configured to function as a site utility power hub 01 capable of providing additional power to one or more internal or external power-intensive components. For example, the base unit 01 may be attached to site utility power instead of running from a battery and contain one or more power ports that relay the site utility power and allow one or more external power-intensive components to be plugged into it. A
power intensive component may include a high-performance gas or dust sensor or wireless communications device such as a wireless gateway, router, or repeater.
It may be further desirable in certain embodiments to configure this base unit to function as a wireless communications hub 01 for various devices in use around the site that are not necessarily part of the present system. Accordingly, the base unit functioning as a communications hub 01 may contain one or more wireless receivers, transceivers, gateways, and/or repeaters capable of providing wireless connectivity on various frequency bands and/or using various wireless communications protocols known to those in the art. The base unit 01 functioning as a communications hub may further contain one or more active and/or passive radio-frequency identification (RFID) readers for detecting active and/or passive RFID tags, respectively, located on or near the site. For example, to track any equipment worth more than a certain amount, a site operator may install one or more transmitters, transceivers, RFID tags, or other communicative devices known in the art to said equipment such that the base unit 01 functioning as a communications hub may identify and/or locate the equipment over the appropriate frequency band. Such a base unit 01 may further contain one or more power outlets configured to relay and provide site utility power to external sensors 23, 424, peripherals 30, and/or other power-intensive components around the site.
A base unit 01 may also be designed to function as a storage hub and be made significantly larger in size than a typical base unit. For example, a base unit 01 functioning as a storage hub may contain specialized cavities for storing typical base units 01, sensors 20, 23, sensor arrays 24, 424, peripherals 30, and/or other equipment leading up to a deployment of the present system at a site.
A base unit 01 may be configured to function as a power pillar that incorporates any or all of the functionality of a site utility power hub, wireless communications hub, and/or storage hub discussed above. The power pillar may include additional internal components including an emergency alert light, battery backup and/or uninterruptible power supply (UPS), user interface and/or display, or other components enabling it to better function as a hub of power, communications, and/or storage.
Base units 01 may be further configured to perform self-diagnostics and/or generate reports concerning the status of connected sensors, peripherals, and other connected internal and external system components. A base unit 01 may store in its own memory or memories 39, 40 and/or send such diagnostic information to any connected component including another base unit 01 or a server 04 where it may be subsequently accessed by a user or by a software component of the system. For example, the base unit 01 can detect and communicate information relating to battery status, component health, sensor health, calibration, and/or other diagnostics. The information may be sent, for example, to a connected user's handset where they may view said information, or to the server 04 where it may be stored in one or more databases for subsequent access. Each base unit 01, sensor 20, 23, 24, 424, peripheral 30, and/or other system component may further contain a unique identifier (for example a serial number) allowing the system to uniquely identify each system component in the course of performing the various functions disclosed herein.
In various embodiments, base units 01 may be further configured to enable the system to identify and track potential intruders or security breaches using the various sensor types and combinations discussed herein. For example, a combination of thermal sensors, microphones, IR
sensors, and/or any of the other sensor types disclosed herein may be used to detect intruder or security related events. The base unit 01 may notify appropriate security and/or emergency personnel (for example police) responsive to detecting an intruder or other security breach.

FIG. 4 depicts a collection of external sensor modules forming an external sensor array 424 that may contain humidity sensor(s), moisture sensor(s), and/or water contact sensor(s) intended to monitor for the specific condition of water ingress within an exterior wall of a building. Illustratively, the sensor array 424 is deployed surrounding a window frame, within the wall. It should be understood that while the following description references deployment surrounding a window frame, the sensor array 424 may be placed in any location. Data from humidity sensor(s), moisture sensor(s), and/or water contact sensor(s) may be processed by a microprocessor and wirelessly (or by a wired connection) transmitted to a base unit 01, and further wirelessly (or by a wired connection) transmitted to the server 04, analytic system, and/or additional software platform.
A further embodiment of an internal sensor 20, external sensor module 23, and/or sensor array 24, 424 may contain temperature sensor(s) intended to monitor for the specific condition of pipe freezing within a wall of a building. The external sensor module 23 and/or external sensor array 424 may be mounted directly to water pipes within wall cavities suspected of having a high risk of freezing when the site is exposed to low environmental temperatures.
Data from temperature sensor(s) may be processed by a microprocessor and wirelessly transmitted to a base unit 01, and further wirelessly (or by a wired connection) transmitted to the server 04 and software platform. A third embodiment of an internal sensor 20, external sensor module 23, and/or sensor array 24, 424 may contain temperature sensor(s) and humidity sensor(s) intended to monitor for the specific condition of mold growth within a wall of a building. An external sensor module 23 or external sensor array 424 may be mounted within wall cavities suspected of having an increased risk of mold growth. Data from temperature sensor(s) and humidity sensor(s) may be wirelessly (or by a wired connection) transmitted to a base unit 01, and further wirelessly (or by a wired connection) transmitted to the server 04, analytic system, and/or additional software platform. In certain embodiments, the data may first be processed by a controller or microprocessor embedded in or coupled to internal sensor 20, external sensor module 23, and/or sensor array 24, 424 prior to transmission.
Internal sensor 20, external sensor module 23, and/or sensor array 24, 424 may be embodied as a moisture sensor 525. FIG. 5 is a diagram of one embodiment of a pin type moisture sensor 525 communicating with base unit 01 via a wired connection.
Moisture sensor 525 may be mounted within the cavity of a wall during the construction of a building, with the pins inserted into the interior side of the building envelope substrate 526.
Alternatively, moisture sensor 525 may be mounted with the pins inserted into the facade 527 side of the building substrate 526. A plurality of moisture sensor(s) 525 may be wired together to allow for extended moisture monitoring of one region of the substrate 526.
FIGS. 6A ¨ 6D show different views of an embodiment of moisture sensor 525. In this embodiment, moisture sensor 525 is a pin type moisture sensor. Pins 628 are designed with barbs to hold moisture sensor 525 in substrate 526 after insertion, securing contact between the substrate and pins. The two pins 628 are implemented to measure the resistance through a specified, uniform distance of substrate, at a certain depth into the substrate. In an alternative embodiment, four pins 628 may be used to measure moisture at two different depth levels within the substrate. Pins 628 may be manufactured from copper, stainless steel, titanium, or other related materials/alloys to make them resistant to corrosion. Base section 629 of the moisture .. sensor 525 may be made using a printed circuit board to hold strict tolerances of distance between the pins 628 and to connect the pins 628 to external wiring. A printed circuit board within base section 629 may contain electronics including resistors and voltage comparator(s).
Alternatively, a printed circuit board within base section 629 may contain no electronics and be comprised strictly of pins 628, internal traces, and external wiring with secured contacts.
All circuitry needed for operation and reading of moisture sensor 525 may be contained within a base unit 01 or externally on the sensor cable connecting the base section 629 to the base unit 01. This will allow the moisture sensor 525 to be cheap, disposable, and safe to be deemed a "sacrificial sensor" and permanently left within the wall cavity after removal of the base unit 01 from the site. One embodiment of the base section 629 includes the electrical circuitry, removing the need of the circuitry to be built into the base unit 01 or on an external sensor cable. Base section 629 will encapsulate all open, conductive material except for pins 628, effectively making moisture sensor 525 assembly and wiring waterproof.
Base section 629 and pins 628 may be designed in a fashion to allow the moisture sensor 525 to be inserted into the substrate 526 in the same fashion as one would push a tack into a tackboard.
Base unit(s) 01 may be able to detect if wireless communication to the server 04 is interrupted or disconnected and alternatively default into an access point mode, where nearby base unit(s) 01 may be able to connect to each other. This will create a mesh network between localized base unit(s) 01, and allow for localized data processing of data generated by a plurality of base unit(s) 01. Data from all of the base unit(s) 01 may be wireles sly transmitted to server 04 when one of the now mesh network connected base unit(s) 01 regains connection to the server 04.
Those skilled in the art will appreciate that numerous modifications and variations may be made to the above disclosed embodiments without departing from the spirit and scope of the present invention.
FIGS. 7A and 7B depict two embodiments of graphical zone maps 700 depicting one or more parameters detected by a plurality of sensors disposed at a monitoring site or sites. The zone maps 700 comprise a graphical representation of monitoring data shown visually in real time, near real time, or at other desired times. The maps 700 further comprise a plurality of zones 710 each corresponding to a respective area of a building floorplan or site map 702 and a sensing location 705. In various embodiments, a sensing location 705 corresponds to the location of one or more base units 01 and/or one or more external sensors 23 or sensor arrays 24, 424 communicatively coupled to the monitoring system. In some embodiments, the size of each zone 710 may correspond to an absolute or preferred monitoring range of the one or more base units 01 and/or one or more external sensors 23 or sensor arrays 24, 424 disposed at each corresponding sensing location 705. Authorized users of the monitoring system may access a zone map via the server or an enabled base unit, either remotely, for example, via the internet, or locally through a direct wired or wireless connection known to those in the art. In some embodiments, the system may be programmed to determine a plurality of zones 710 each corresponding to a sensing location 705 corresponding to one or more ranges, sensor types, or other relevant characteristics of the one or more base units 01 and/or one or more external sensors 23 or external sensor arrays 424 disposed at each corresponding sensing location 705, or corresponding to one or more site characteristics or sources of external information received by the analytic system as described with respect to FIGS. 11A-11B and 12.
FIG. 7A depicts an embodiment of a continuous or analog zone map. Each zone corresponds to a sensing location 705 corresponding to sensing equipment that includes one or more base units 01 and/or one or more external sensors 23 or external sensor arrays 424 capable of detecting a range of values of one or more parameters occurring in or proximate to the corresponding zone 710 at a certain time. For example, the sensing equipment at sensing location 705d may be able to display a gradient of relative humidity (RH) values spatially distributed throughout the corresponding zone 710d in accordance with the legend 701. In other embodiments, the sensing equipment disposed at a sensing location 705 may be able to detect a plurality of values of a single parameter associated with different spatial regions of the corresponding zone 710 that do not correspond to a gradient or any other known pattern. In some embodiments, the sensing equipment disposed at sensing location 705d can depict a composite value derived from multiple sensed parameters that represents the likelihood or other status of a specified event. For example, a combination of sensed humidity and temperature parameters can be combined into a single representation of how many days until mold is likely to grow. Parameter legend 701 associates a range of color values with a value of a certain parameter. Parameter legend 701 may alternatively use shading, saturation, focus, and other continuous values known to those in the art to identify particular values of a parameter. In some embodiments, zones of the zone map showing unacceptable or important values of a measured parameter and/or undesirable or important rates of change in a measured parameter may be identified by blinking or other form of animation.
A sensor location 705 may further possess one or more sensor status indicators 722 each indicating one or more statuses and/or properties of a base unit 01, external sensor 23, or external sensor array 424 corresponding to that sensing location 705. For example, a sensor status indicator 705 may indicate that the base unit 01 located at sensing location 705b has a light 37 that is turned on.

In some embodiments, a zone map may further contain one or more component indicators 720 identifying said component and/or representing one or more aspects of its position or status.
A component may be a peripheral 30, base unit 01 not currently being treated as a sensing location 705 by the current zone map, external sensor or sensor array not currently being treated as a sensing location 705 by the current zone map, or other component being monitored and/or controlled by the system. One or more component status indicators 721 may further be included on the zone map indicating one or more statuses or properties of the associated component.
An example of sensor status indicators 722 and/or component status indicators 721 may be an arrow representing the orientation of and/or direction or speed of travel of the corresponding base unit, piece of sensing equipment, or component. Other examples include status indicators that represent an elapsed time since previous calibration, battery status indicators, and indicators of other self-diagnostic data.
The information displayed by one or more system component icons including sensor locations 705, sensor status indicators 722, component indicators 720, and/or component status indicators 721 may be further used to assist in calibrating system components including base units 01, sensors 20, 23, 24, 424, peripherals 30, and/or other components communicatively coupled to the system. Calibration may be performed manually by a user by adjusting an operating mode of a system component responsive to the information conveyed by the various system component icons. In some embodiments, the system may be programmed to perform .. automatic calibration responsive to determining that one or more statuses of one or more system components meets or exceeds one or more known thresholds.
FIG. 7B depicts an embodiment of a discrete zone map. Each zone 710 corresponds to a sensing location 705 containing sensing equipment that includes one or more base units 01 and/or one or more external sensors 23 or external sensor arrays 424 capable of detecting a finite amount of values of one or more parameters occurring in or proximate to the corresponding zone 710 at a certain time. For example, in the present figure the sensing equipment disposed at sensing location 705f can be assigned exclusively to zone 710f and depict the value of the parameter representing how many days until mold is likely to grow within that zone. In some embodiments, the sensing equipment disposed at sensing location 705f can depict a composite value derived from multiple sensed parameters that represents the likelihood or other status of a specified event. For example, a combination of sensed humidity and temperature parameters can be combined into a single representation of how many days until mold is likely to grow. In other embodiments, a zone can be divided into one or more sub-zone, each sub-zone corresponding to its own discrete parameter value or continuous range of parameter values. For example, the sensing equipment corresponding to sensing location 705e can be assigned exclusively to monitor zone 710e, which is further divided into first sub-zone 711e and second sub-zone 712e.
A first subset of the sensing equipment corresponding to sensing location 705e can be assigned to monitor sub-zone 711e, while a second subset of the sensing equipment corresponding to sensing location 705e can be assigned to monitor sub-zone 712e. In accordance with the legend 701, the discrete zone map can simultaneously depict a different parameter value in the first sub-zone 711e versus the second sub-zone 712e. In other embodiments, multiple groups of sensing equipment, for example, the sensing equipment corresponding the sensing locations 706g and 707g may be assigned to monitor a single zone, for example, zone 710g. A
sensor legend 750 may also be provided and contain identifying and/or status information about the types of sensors and/or base units disposed throughout the floorplan 702, for example, the type of each piece of sensing equipment, whether the piece of sensing equipment is mobile or stationary, the location of each piece of sensing equipment, or any other applicable sensing equipment characteristics.
A discrete or continuous zone map may also comprise a coverage map that depicts sensor deployment information without depicting any sensed parameters. For example, a coverage map may depict sensor type, location, ranges, recommended zones, and/or additional sensor characteristics to help system users develop a monitoring plan and/or assess monitoring capabilities.
Any and all features described with reference to a discrete zone or map may be applied to a continuous zone map and vice versa wherever applicable. Zone maps may be hybrids in which some zones are continuous while others are discrete with respect to any or all of parameters represented. Some zones may be configured to represent some parameters as continuous, but represent other parameters as discrete. Different zones and sub-zones may be monitored by and associated with any one of a base unit, sensor, group of sensors, or any combination thereof.
Although FIGS. 7A and 7B depict two-dimensional zone maps each corresponding to a two-dimensional floorplan, a three-dimensional zone map may also be used corresponding to a three-dimensional representation of the site or sites being monitored. A zone map may also be provided as a simulation not corresponding to any current placement of base units to assist in simulating prospective monitoring deployments in advance.
The system may further be configured to provide a monitoring and/or control interface containing text or icons representing any or all of the features discussed in FIGS. 7A and/or 7B
or throughout this disclosure. The monitoring and/or control interface may allow a user to observe the status of and/or control the operation of one or more of said components responsive to an action such as clicking on the appropriate text, link, and/or icons. For example, the system may indicate that a component is malfunctioning, and a user may click on the appropriate icon to disable said component. The monitoring and/or control interface may further contain additional features such as the option to send external notifications, alerts, and/or reports responsive to user action. The monitoring and/or control interface may further permit a user to manually control the operation of one or more base units 01, sensors and sensor arrays 20, 23, 24, 424, peripherals 30, or other components disposed around the site and communicatively coupled to the present system. For example, a user may learn via the monitoring interface that a connected piece of equipment was accidentally left on after the construction crew left and may, in response, use the control interface to disable said connected piece of equipment. In another example, a user may observe via the monitoring interface that conditions indicative of ice are present and, in response, may increase the operation of one or more heaters and/or fans in order to better disperse heat around one or more areas of the site.
FIG. 8 depicts an embodiment of a graphical output produced by one or more methods of predicting, detecting, analyzing, and/or depicting an event based on more than one parameter, for example, a first parameter 850, a second parameter 860, and a third parameter 870. The graphical output, the information contained within the graphical output, and the one or more methods used to produce the graphical output may be used in conjunction with the modes of event and preliminary event prediction and response described, for example, in FIGS. 9, 11A, 11B, and 12. In the current example, a water leak event may be predicted based on a temperature parameter 850, humidity parameter 860, and a particulate level parameter 870.
In some embodiments, a first time 810 can be identified when the temperature and humidity parameters begin to change at a rate indicative of a possible water leak event and the particulate level begins to rise at a rate also consistent with a possible water leak event. A
second time 820 can be identified after the temperate and humidity parameters have stabilized and the particulate level has stabilized. A third time 830 can be identified when the temperature and humidity values begin to return to their previous values before time 810.
And lastly, a fourth time 840 can be identified once conditions substantially return to their state prior to the first time 810. This method may be applied to any type or number of parameters capable of being monitored by the present monitoring system, and any type or number of times, events, or preliminary events capable of being tracked and/or identified by the present monitoring system.
In some embodiments, the monitoring system may provide a graphical report of a complex event depicting traces of the parameters involved and/or significant times corresponding to one or more stages of the complex event. As in shown in FIG.
8, the report may include an event timeline 806 listing and describing the significance of each significant time. The report may further include any or all of a listing of the event type 805, the status of any alerts sent in connection with the event at issue 803, alert recipients 802, current event status 804, and any other visual indicators that would assist a user in identifying, monitoring, detecting, depicting, predicting, responding to, or otherwise handling an event at a site being monitored. A
legend 801 may also be displayed to visually identify each parameter 850, 860, and/or 870.
FIG. 9 depicts a flowchart of a method 900 of one embodiment of the analytic portion of a monitoring system as disclosed herein performing event prediction and response at one or more sites being monitored by the monitoring system. Event prediction and response method 900 begins at act 902 and involves act 904¨receiving information and/or accessing the locations, types, and other properties of the one or more sensors connected to or installed in the one or more base units 01 at the site being monitored. The system further receives information describing characteristics of the site itself, including site physical layout and/or dimensions, site environmental conditions including location, climate, or weather, selected site preferences including worker condition thresholds, and current and historical data trends, customer imposed .. thresholds, micro-weather station data, and/or other site environmental parameters. At act 905, the system determines plausible events or preliminary events that are detectable at the given site based on the information received at act 904. At act 906, the analytic system receives and/or accesses data tailored to the specific configuration of the present site or sites being monitored based on the data received and/or accessed.
The system may maintain one or more databases of previous monitoring and response operations conducted at different sites including the types and locations of various equipment deployed at the site and information surrounding events, preliminary events, and/or other actions that were logged at that site. The system may be further configured to store additional information in a database including site configurations and statuses at different times, environmental statues (for example ambient weather conditions) at different times, base unit .. configurations and statuses at different times, sensor configurations and statuses at different times, and/or event statuses at different times. This database may be used in connection with any of the data lookup or comparison functions performed within the scope of this disclosure. For example, the system may associate a present site with one or more previous sites containing a similar physical and/or environmental layout and similar base unit and/or sensor configuration, .. and predict, based on events that were detected at the previous sites, one or more events that are more likely to occur at the current site. Such predictions may enhance monitoring and/or response operations at the current site by putting the system and/or system users on notice of elevated sources of risk. Such associations may also assist system users in setting up operations at a new site and/or reconfiguring operations at an existing site. For example, the database associations may assist system users in selecting the number, type, location, and/or operating mode of one or more base units 01, sensors and sensor arrays 20, 23, 24, 424, peripherals 30, and/or other connected system components.
Act 906 may further include generating a model of the site or sites based on the information received in acts 904-906. In one embodiment, the tailored data is received and/or accessed pursuant to one of the database selection methods depicted in FIGS.
11A-11C, however the analytic system may receive and/or access data used to perform event prediction via an alternate method or source. At act 908, the analytic system uses the site configuration data received and/or accessed during act 904 and the tailored data received and/or accessed during act 906 to determine one or more parameter thresholds corresponding to one or more events and/or preliminary events. A preliminary event may be an event that may be indicative of a potential or imminent occurrence of an undesirable or important event. For example, a preliminary event may be an increase in temperature beyond a certain threshold, which may be indicative of an increased likelihood of a possible fire. In some embodiments, an event or preliminary event may be indicated by a plurality of parameter thresholds instead of a single parameter threshold.
At act 910, the analytic system receives monitoring data from the one or more sensors at the one or more sites. At act 912, the system compares the data received during the previous step to the parameter thresholds determined during act 908 to determine whether an event is in progress. The analytic system comprises a memory that stores associations between certain types or configurations of parameter thresholds and certain events or, in some embodiments, preliminary events.
In some embodiments, the event prediction and response system 900 further comprises the ability to detect preliminary or suspected events. If an event is not detected, the system proceeds to act 916 to determine whether a preliminary event is in progress based on stored associations between monitoring data and various preliminary event types. If a preliminary event is not detected, the system resets, pauses, repeats or otherwise continues with its current programming depending on the desired embodiment. If the system detects a preliminary event, at act 918 the system may issue a preliminary event alert and/or take responsive action. For example, in some embodiments the system may be coupled to one or more actuators 30 capable of controlling the operating mode of one or more fans disposed near one or more heaters at the site being monitored. If a preliminary event is detected suggesting that cold conditions are approaching, then at act 918 the system may take proactive/corrective action by controlling the one or more actuators 30 to turn ON or increase the speed of the one or more fans located near the heaters in order to disperse heat at the site more effectively. A
preliminary event alert may comprise any form of alert, notification, or communication with an external user or entity, for example, mobile user 05, desktop user 06, or other type of user or entity.
In some additional embodiments, at act 920 the system may actively monitor and/or change the configuration, power, or other settings of one or more sensors or related components and systems. In addition to storing associations between certain types or configurations of parameter thresholds and certain preliminary events, analytic system may also store associations between certain preliminary events and certain events. Analytic system may store additional associations between certain parameter thresholds and certain events responsive to the one or more events being associated with the preliminary event at issue. Using these associations, the analytic system can alter the programming of the monitoring system to prioritize detection of the associated events. In some embodiments, the system may also use the associations to perform additional or different response measures at the one or more sites being monitored.
In one embodiment, detecting a preliminary or suspected event 916 involves using one or more infrared sensors to map a gradient of infrared light intensity, power, energy, or a related property. Responsive to one or more infrared light properties meeting or exceeding one or more thresholds the determination that a preliminary event has occurred can be made and a preliminary alert or responsive action may be issued (act 918) corresponding to the type of preliminary event involved.
At act 920, the system may change an operating mode or characteristic of one or more base units, servers, handsets, sensors, actuators, and/or other system components responsive to the detection of a preliminary event during act 916. For example, the system may change the frequency at which the central controller and/or base unit reads or analyzes sensor data. In some embodiments, the system may change the frequency at which a sensor or sensors receive or transmit new data, or the conditions under which a sensor or sensors receive or transmit new data. In other embodiments, the system may change the power drawn by one or more base units or other system components. In other embodiments, the system may toggle whether one or more system components are in an ON state versus an OFF state. For example, if a preliminary event indicating a heightened risk of fire is detected, the system may activate, increase the refresh frequency of, or increase the power provided to one or more base units and/or sensors associated with fire detection.
In some embodiments, taking responsive action during acts 914 and/or 918 involves communicatively coupling one or more actuators, controllers, or other peripheral devices 30 to one or more base units. Each peripheral may be coupled to one or more objects, devices, or systems at the site or sites being monitored and may be configured to control one or more aspects of operation responsive to an event determination made during act 912 or a preliminary event determination made during acts 916, 920, and/or 922. For example, a base unit may be communicatively coupled to a valve actuator disposed in a fluid pipe and configured to control the operation of said valve responsive to detection of a fire event. Said actuators may be disposed within a base unit or outside of a base unit depending on the desired configuration and type of actuator. Base units may be further configured to control the operation of various types of on-site equipment including lighting, fans, heating, humidifiers, dehumidifiers, and/or other controllable equipment or fixtures disposed in, on, or around the site(s) being monitored.
In other embodiments, taking a responsive action at acts 914 and/or 918 involves automatically taking corrective or preventive action to ensure that damage or risk from an event is minimized or avoided altogether. For example, if a motion sensor detects an event or preliminary event corresponding to a suspected intruder, the system may be automatically configured to activate one or more lights around the site to deter or scare off the intruder prior to initiating a full alarm or other response. In another example, if a temperature sensor detects a frozen pipe, the system may be automatically configured to determine whether increasing the operation of one or more heaters would be sufficient to unfreeze the pipe and initiate the necessary operation of said heaters in response.
In various embodiments, the system may generate a written, audiovisual, or partially written and partially audiovisual report responsive to the detection, suspicion, and/or conclusion of an event and/or preliminary event. An example of a hybrid written-audiovisual report is depicted in FIG. 8. The generation of such a report may occur during any of acts 902-924.
FIG. 10 depicts a flowchart of one embodiment of a method 1000 for configuring a network of base units 01 within a monitoring system as disclosed herein. The method begins at act 1002. At act 1004, a base unit determines whether it can connect to the server 04 either directly or via a router, gateway, or other wired or wireless mode of communication known to those in the art. If so, at act 1006 the base unit assumes a first mode of operation. If not, in some embodiments the system may proceed directly to act 1010 and assume a second mode of operation. In other embodiments, the base unit proceeds to act 1008 and determines whether any connections to additional base units or other networked devices are available.
If so, at act 1012 the base unit connects to the one or more additional base units or other networked devices. In some embodiments, the base unit may proceed directly to act 1016 or 1020 and assume a third or fourth mode of operation, respectively.
In other embodiments, at act 1014 the base unit may determine whether any of the additional base units are currently in a third or fourth mode of operation and, in response, may assume either the third or fourth mode of operation. In other embodiments, at act 1018, responsive to determining that one or more of the additional base units is or is not in a third or fourth mode of operation, the base unit may determine whether the one or more additional base units is qualified, capable, or configured to control a local network of base units. In act 1020, responsive to the determination in act 1018, the base unit may enter a mode of operation in which it controls a local network of base units. In act 1016, responsive to a determination in act 1018 that it is not qualified, capable, or configured to control a local network of base units, the base unit may enter a mode of operation in which it does not control a local network of base units. The local network may be wired, wireless, or both and may take on any number of different architectures known to those in the art including, but not limited to, P2P and mesh configurations. For example, in a third mode of operation the base unit may be configured to function in a local network of base units wherein a different base unit has been designated as the leader or master. In some embodiments, entering a fourth mode of operation involves the base unit assuming control of a local network of multiple base units. In other embodiments, entering a first mode of operation involves the base unit connecting to a server capable of controlling the monitoring system. In other embodiments, entering a second mode of operation involves the base unit operating autonomously without connecting to a server, additional base unit, or other system control device.
FIGS. 11A and 11B depict flowcharts of embodiments of methods 1100 for detecting and/or retrieving information used to perform event prediction, response, and reporting as is described, for example, in FIGS. 7-9, or for another purpose involving data being detected or retrieved in accordance with the present disclosure.
FIG. 11A depicts a flowchart of an embodiment of a method for detecting and retrieving data relevant to a site or sites being monitored. The method begins at act 1102. In one embodiment, at act 1104 the analytic system receives information identifying the locations and types of sensors operating at a site or sites being monitored. At act 1106, the system receives any available aggregate data relevant to the site or sites being monitored.
Aggregate data may comprise preconfigured libraries or databases tailored to particular types of sites or sensor arrangements or drawn from a plurality of external sites or sources. Aggregate data may comprise data that has been previously processed or manipulated to consolidate or extrapolate important values in advance of retrieval.
At act 1108, the system retrieves any available data from a substantially relevant site. A
substantially relevant site may comprise a site possessing a similar floorplan, located in a similar environment, managed by the same owner, having the same general contractor or subcontractor, being the same building type, possessing a similar sensor configuration or risk of exposure to certain events, or any other source of similarity that increases the likelihood that the site's information will be relevant to the site being monitored. At act 1110, the system can widen its search to retrieve data from additional sites that are relevant to the site or sites being monitored, but to a lesser degree than sites identified in act 1108. At act 1112, the system can further widen its search to retrieve data from additional sites which were not sufficiently relevant to be included during acts 1108 or 1110. Lastly, at act 1114 the system retrieves any other relevant data it can find from external sources not necessarily associated with site data, for example, data found on the Internet, industrial or scientific data, data sourced from partner companies, weather prediction data, data owned or possessed by third-parties, and/or other sources of data relevant to determining events and associated parameter thresholds at the site being monitored.
After receiving the data of acts 1104-1114, at act 1116 the system determines whether it can generate prediction values for any events or preliminary events at the site or sites being monitored based on the data received. If not, the system can proceed to act 1124 and restart the process when desired. If so, the system can proceed to act 1120 or, in some embodiments, directly to act 1122. At act 1120 the system proceeds to determine one or more events or preliminary events the system is capable of monitoring, detecting, or predicting at the site or sites being monitored based on the data received in acts 1104, 1006, 1008, 1110, 1112, and/or 1114.
At act 1122, the system uses the determinations made in the previous act to determine one or more parameter threshold values corresponding to each event or preliminary event.
FIG. 11B depicts an alternate embodiment of the method for detecting and retrieving data relevant to a site or sites being monitored. Acts 1154, 1156, 1158, 1160, 1162, and 1164 are similar to acts 1104, 1106, 1108, 1110, 1112, and 1114 described in FIG. 11A, respectively, however, instead of retrieving the data involved in each act, the system accesses all or part of the data without downloading said data in its entirety and determines whether the accessed data possesses the desired degree of relevance to the site or sites being monitored. For example, the system may receive metadata, index, or summary information describing the data, parse through all or part of the data in memory without downloading the entirety of said data to memory, or perform some other action that allows it to analyze the relevance of the data to a particular site or sites without using as much bandwidth, power, processing capability, or other resource associated with the analytic system as compared to the embodiment illustrated in FIG. 11A.
After determining the availability of any data in acts 1154-1164, at act 1166 the system determines whether it can generate prediction values for any events or preliminary events at the site or sites being monitored based on the data. If not, in some embodiments the system can proceed to act 1174 and restart the process when desired. If so, at act 1168 the system retrieves some or all of the data determined to be available. At act 1170 the system proceeds to associate particular data with particular events or preliminary events. At act 1172, the system uses the associations made in the previous step to determine one or more parameter thresholds or patterns corresponding to each event or preliminary event.
In various embodiments of the methods illustrated in FIGS. 11A and 11B, the system may skip any or all of acts 1106-1114 or 1156-1164 depending on the desired configuration. In the case of FIG. 11A, the system may proceed directly from any of acts 1104, 1106, 1108, 1110, 1112, or 1114 to act 1116 depending on the desired configuration. In the case of FIG. 11B, the system may proceed directly from any of acts 1154, 1156, 1158, 1160, 1162, or 1164 to act 1166 depending on the desired configuration.
FIG. 12 describes another embodiment of a method for detecting and retrieving data relevant to a site or sites being monitored. Acts 1206, 1208, and 1210 operate similarly to acts 1156, 1158, and 1160 in FIG. 11B, respectively. However, if the system determines that there is relevant data at any of acts 1206, 1208, or 1210 it proceeds directly to one of acts 1207, 1209, or 1211, respectively, each of which operate similarly to acts 1116 and/or 1166 in FIGS. 11A and 11B, respectively. If an event association can be made at that time or if the system has already reached act 1214, the system proceeds to act 1218, which functions similarly to act 1168 in FIG.
11B. If no event association can be made at act 1207, 1209, or 1211, the system instead proceeds to one of act 1208, 1210, or 1214, respectively. Acts 1220 and 1222 function similarly to respective acts 1170 and 1172 shown in FIG. 11B.
FIG. 13 illustrates another embodiment of a base unit 01. Base unit 01 may have a front housing plate 1310 covering the front surface and part of the lateral surfaces. Front housing plate 1310 may also contain any or all of the features described herein with respect to front housing surface 310 in FIG. 3A. Base unit 01 may further have a rear housing plate 1340 covering the rear surface and all or part of the remaining lateral surfaces not covered by front housing plate 1310. In some embodiments, the lateral portions of front housing plate 1310 may abut all or part of the lateral portions of rear housing plate 1340. Rear housing plate 1340 may also contain any or all of the features described herein with respect to rear housing surface 340, lateral housing surface 320, and/or lateral housing segments 322 and 323 as depicted in FIG. 3A.
In some embodiments, a base unit 01 may further comprise one or more secondary apertures 1314. A secondary aperture 1314 may, for example, function as a vent or filter to allow and/or restrict various types or quantities of air or other gasses, particulates, and/or moisture from entering the base unit 01 similar to the apertures 311.
Secondary aperture 1314 may further be covered by, fitted with, or integral with one or more secondary aperture gratings similar to sensor aperture gratings 312 depicted in FIGS. 3A and 3B.
In some embodiments, a base unit 01 may further comprise a set of secondary housing surfaces 1355 that are not flush with the other housing surfaces or plates disclosed herein. The set of secondary housing surfaces 1355 may abut and/or be fixedly attached to one or more of the other housing surfaces described herein. For example, a secondary lateral housing plate 1353 may abut and be fixedly attached to rear housing plate 1340. A secondary rear housing surface 1354 is pictured in FIG. 13, however the set of secondary housing surfaces 1355 may comprise any shape and combination of front, lateral, or rear surfaces, plates, segments, and edges disclosed herein in FIGS. 3A-3D. A V-groove or U-groove 1352 may be shaped into and/or carved out from the any or all of the front, lateral, or rear surfaces, plates, segments disclosed herein in FIGS. 3A-3D and adapted to allow the base unit 01 to better engage a secondary surface or object, for example, a pipe. For example, a V-groove or U-groove 1352 may be shaped into and carved out of secondary rear housing surface 1354 and secondary lateral housing plate 1353, respectively. A mounting strap 1371 may be further attached to one or more housing surfaces, plates, segments, and/or edges and adapted to fixedly mount the base unit 01 on a secondary object or surface, for example, a pipe.

One or more pieces of webbing 1372 may be fixedly attached to any or all of the surfaces, plates, segments, edges, and vertices described herein. In some embodiments, some or all of the webbing 1372 may be adapted to be reflective making the base unit 01 easier to identify. Rear housing plate 1340 may be segmented into one or more rear housing plate segments, for example, elements 1348 and 1349, each which may be separated by one or more corresponding rear housing plate vertices 1321. Rear housing plate segments 1348, 1349 may be integral with or abut each other and/or each respective rear housing plate vertex 1321. In various embodiments, each rear housing plate 1340, rear housing plate segment 1348, 1349, and/or rear housing plate vertex 1321 may be integral with, abut, be flush with or offset from, or otherwise be disposed proximate to each corresponding front housing plate 1310, front housing plate segment 1307-1308, and/or front housing plate vertex 1309 in accordance with a desired shape or configuration.
In various embodiments, one or more mounting hooks 1373 may each be fixedly attached to one or more portions of the base unit's housing and configured to allow the base unit to hang from an object, for example, a screw or a nail, or a surface disposed on or around the site being monitored.
Mounting strap 1371 functions similarly to the mounting strap 1371 disclosed in FIGS. 13 and 17.
FIG. 16 depicts a flowchart of one embodiment of a method 1600 for determining, by one or more servers or controllers of the monitoring system disclosed herein, an extent to which one or more sites being monitored are in compliance with one or more insurance or regulatory requirements and/or parameters. The system begins at act 1602. At act 1604, the system receives applicable insurance or compliance requirements associated with a site or sites being monitored. At act 1606, the system receives applicable site configuration and/or monitoring data. At act 1608, the system calculates one or more compliance grades or thresholds based on the information received during acts 1604 and 1606. For example, noise levels or vibration levels may be summarized to be reported, or room occupancy data may be summarized to be reported in accordance with contractor safety programs.

In some embodiments, the system may proceed directly to acts 1614 or 1616, or return to act 1602 at a desired interval or schedule, or responsive to one or more conditions. In other embodiments, the system proceeds to act 1610 and determines whether one or more grades or thresholds derived in act 1606 has been satisfied to a certain degree. If not, the system may proceed directly to acts 1614 or 1616, or returns to act 1602 at a desired interval or schedule, or responsive to one or more conditions. If so, the system proceeds to act 1612 and determines whether it is time to generate one or more alerts and/or reports based on the results of act 1610.
If not, the system may proceed directly to act 1616 or return to act 1602 at a desired interval or schedule, or responsive to one or more conditions. If so, the system proceeds to act 1614 and .. generates one or more alerts and/or reports based on the results of act 1610. For example, the system may generate a report which summarizes the real-time risk over a period of time, a report detailing conditions during an installation, or a contractor safety program compliance report. The method finishes at act 1616.
In some embodiments, at some point between acts 1610 and 1616 the system may further be configured to save some or all of the information collected in acts 1608 and/or 1614 as part of a compliance or risk profile. The system may save this information in a historical archive of profiles for later use. The archived profile information may be accessed again during act 1604 to inform the subsequent compliance grades or thresholds generated during act 1608, or again at act 1614 to inform subsequent compliance reports.

The medium may include, for example, a disk or flash memory.
Typically, in operation, the processor causes data to be read from the nonvolatile recording medium 1902 into another memory 1904 that allows for faster access to the information by the processor than does the medium 1902. This memory 1904 is typically a volatile, random access memory such as a dynamic random-access memory (DRAM) or static memory (SRAM). It may be located in storage system 1812, as shown, or in memory system 1804. The processor 1802 generally manipulates the data within the integrated circuit memory 1904 and then copies the data to the medium 1902 after processing is completed.

FIG. 20 depicts an additional embodiment of a base unit configured to detect its orientation and/or perform image processing using one or more cameras 2005 communicatively coupled to the one or more controllers 18 within the base unit 01. One or more sensors capable of detecting orientation and/or directional information, such as a magnetic sensor or accelerometer may be disposed in or communicatively coupled to the base unit 01 and provide an orientation of the base unit 01. For example, an accelerometer may use a three-dimensional Cartesian coordinate system x-y-z to detect a positive or negative force of gravity g acting on one .. or more of the axes x, y, and/or z. A magnetic sensor may be further configured to detect an orientation relative to geographic directions North, South, East, West, up, and/or down. The system may then associate the appropriate x-y-z directions with corresponding geographic directions North, South, East, West, up, and/or down. Using the information collected by the sensors and the known relationship between the coordinate system and geographic directions, the base unit may determine its current orientation.
An additional sensor 20 may have a range or area of detection that partially or completely overlaps a range or area of detection corresponding to the one or more cameras 2005. For example, an IR sensor 20 may have a cone of detection with an angle 0 and a camera 2005 may have a cone of detection with an angle a. If the IR sensor 20, for example, detects a sudden .. change in the thermal distribution within its cone of detection, then the system may be programmed to activate the camera 2005 in response and perform image processing on the images captured by the camera 2005 to identify the object or phenomenon that caused the thermal anomaly. In certain embodiments, the sensors 20 and/or cameras 2005 involved may instead be configured as standalone external sensors 23 or external peripherals 30, respectively, while still being communicatively coupled to at least one base unit 01.
FIGS. 21A and 21B depict two opposing lateral perspectives of an embodiment of a base unit configured to function as a power pillar 01'. The power pillar 01' is encased by a housing 2120 and receives power from an external power supply, for example, from site utility power outlet 2105. Power pillar 01' may further comprise one or more power port surface 2113 each containing one or more power ports 2115 for providing power to one or more external components. Power pillar 01' may also comprise one or more power cables 2116 (ending in a male or female power port) for connecting to site power outlets 2105. For example, if the power pillar 01' cannot be placed directly adjacent to a site power outlet 2105 then power cable 2116 may be used to connect to site power outlet 2105. Power cable 2116 may be partially or fully retractable into the body of the power pillar 01'. The power pillar 01' may further comprise one or more backup batteries and/or UPS devices 2119 for providing backup power to connected components. For example, battery backups and/or UPS devices 2119 may be configured to provide power to one or more connected components in the event that utility power is unavailable or compromised.
Power pillar 01' may also comprise one or more storage cavities 2156, which may each be removably sealed by a hatch 2150 or similar removable sealing apparatus known to those in the art. One or more storage racks or shelves 2110 may be disposed within each storage cavity 2156 and its position within the storage cavity may be removable or adjustable. Each storage cavity may removably contain one or more system components including base units 01, sensors 20, 23 or sensor arrays 24, 424, peripherals 30, and/or other system components to be used around the site being monitored. Storage cavities 2156 and racks 2110 may be used, for example, to removably contain some or all of the equipment to be used at a site when the system is first delivered or to removably store equipment that was already used at the site following the completion of monitoring operations at that site.
Power pillar 01' may further comprise one or more lights 37 for illuminating the site, indicating an alarm or other status information, or for performing other functions of a light known to those in the art. Power pillar 01' may also comprise one or more displays 2126 for visually displaying information, for example, an alarm, site location, or other system or site status information. A display may comprise a digital screen such as an LCD, LED, CRT, OLED, and/or other digital display device known to those in the art. A display 2126 may also function as a user interface (UI) 26 capable of receiving user input in addition to displaying information.
A display 2126 that is also a UI 26 may be a resistive, capacitive, or infrared touchscreen or other user interface known to those in the art. For example, a user may interact with the display 2126 by pressing a request icon on the touchscreen and the power pillar 01' may, in response, bring up on the display 2126 a map of the site with a status icon indicating the current location of the user and power pillar 01' within the site.
FIG. 22 is a perspective view of another embodiment of a base unit 01. The base unit 01 has an elastic mounting strap 1371 including a plurality of mounting strap apertures 1376 disposed along the mounting strap 1371. The base unit 01 further includes a plurality of bullhorns 1375 attached to and protruding away from one or more base unit surfaces, plates, segments, edges, and/or vertices. Since the mounting strap 1371 is made of an elastic material, the mounting strap apertures 1376 may be manually stretched allowing them to slide over and couple with each bullhorn 1375. The base unit 01 further includes a mounting clip 1377 hingedly attached to one or more base unit surfaces, plates, segments, edges, and/or vertices. In FIG. 22, mounting clip 1377 is depicted being hingedly attached to the rear housing surface.
FIG. 23 is a rear view of the embodiment of the base unit 01 shown in FIG. 22.
While not being used, the mounting clip 1377 can hingedly retract inward such that it is substantially flush with the rear housing surface as shown in FIG. 23. When moved into the fully retracted position described above, a mounting clip aperture 1378 disposed near the end of the mounting clip 1377 can mate with a mounting clip tab 1379 and fix the mounting clip 1377 in the retracted position. One or more magnet mounts 1460 may be disposed on the rear housing surface, or on another surface or plate, of the base unit 01 as described above with respect to FIG. 14.
FIG. 24 is a perspective view of another embodiment of a base unit 01. A
mounting strap 1371 is in an unused position and wraps around the lateral periphery of the base unit 01. The unused mounting strap 1371 is arranged in a storage position such that a plurality of mounting strap apertures 1376 disposed on the mounting strap 1371 are each wrapped around and coupled .. to a corresponding bullhorn 1375. A mounting clip 1377 is hingedly withdrawn away from the rear housing surface and coupled to a fixed protrusion 2479 via the mounting clip aperture 1378 such that the base unit 01 is secured in place by the fixed protrusion 2479.
As discussed above, in some examples, base unit(s) 01 may include or be coupled to one or more sensors configured to sense information indicative of water flow, water damage, water presence, water leaks, moisture, and so forth, such as fluid-flow sensors, humidity sensors, moisture sensors, and so forth. Water leaks in buildings may result in significant water damage if not detected and addressed within a short period of time. Water leaks may, in some embodiments, be detected by one or more flow sensors mounted on or in one or more water pipes in a building. Many buildings or residences include only a limited number or even just a .. single water flow sensor, for example, on a main water line used to calculate water consumption to report to a water utility to determine a water bill for the building or residence. One potential problem may be that if an unexpected flow of water is detected with the single water-flow sensor that is indicative of a water leak, one may not be able to easily pinpoint the actual location of the leak. It may be desirable to pinpoint the actual location of the leak so one may quickly be .. directed to the source of the leak to repair it. It may also be desirable to pinpoint the actual location of a water leak so that if one wishes to turn of flow of water through a pipe delivering water to the leak, one may choose a pipe closest to the leak to shut off water flow therethrough, rather than turning off water flow to all areas in a building. One may, for example, wish to continue to utilize water-consuming appliances such as showers, sinks, toilets, and so forth in a building if a leak is present in an unrelated area, for example, in a spare bathroom, rather than disabling these appliances by turning off a main water valve to the building.
It is to be appreciated that the principles of the disclosure are more broadly applicable to fluids other than water and that, in some examples, may be applicable to non-liquid-state matter. Examples may be provided with respect to water for purposes of explanation.
For example, FIG. 25 illustrates a building 2500 having a plurality of rooms or areas 2515, 2535, 2540, 2545. Each room or area of the plurality of rooms or areas 2515, 2535, 2540, 2545 may include one or more sensor units S of a plurality of sensor units S, which may be or include base units, such as the base unit(s) 01. Each of the plurality of rooms or areas 2515, 2535, 2540, 2545 may include one or more fluid-delivery conduits (for example, water-delivery conduits), such as the main water line 2510 and/or the water pipes 2525, 2565, 2570. It is to be appreciated that the main water line 2510 and/or water pipes 2525, 2565, 2570 may contain fluids other than water and that, in some examples, may contain matter other than liquid-state matter.
The main water line 2510 and/or each of the water pipes 2525, 2565, 2570 may include one or more sensors and/or fluid-control valves. For example, the water pipes 2525, 2565, 2570 may each include a fluid-flow sensor 2550, 2555, 2560, respectively, which may sense or detect information indicative of a flow volume of a fluid flow passing therethrough, and may each include a control valve to control a flow of fluid therethrough, such as the control valve 2520 to control a flow of fluid through the water pipe 2525. Similarly, the main water line 2510 may include a fluid-flow sensor 2505 and a control valve 2530. In various examples in which the .. base unit(s) S are implemented as the base unit(s) 01, the external peripherals 30, external sensors 23, and/or external sensor arrays 424 may include one or more of the fluid-flow sensors 2505, 2550, 2555, and/or 2560, and the external peripherals 30 may alternately or additionally include one or more of the control valves 2520, 2530.
The flow sensor 2505 on the main water line 2510 may provide an indication of an unexpected increase in water flow that may be indicative of a water leak somewhere within the building 2500. If the leak is suspected to be occurring in room or area 2515 of the building 2500, one may wish to verify the location of the leak so that if there is a control valve 2520 located on the water pipe 2525 delivering water to the room or area 2515, one may shut off the flow of water through water pipe 2525 using the control valve 2520. One may shut off the water flow to room 2515 using control valve 2520 rather than by turning off a main control valve 2530 so that water may remain available in the other rooms or areas 2535, 2540, 2545 of the building 2500.
It is to be understood that instead of or in addition to the water distribution system of FIG. 25 delivering water to different rooms of a building, for example, a residence, one or more water pipes may deliver water to different areas within a room (e.g., a bathtub and a sink in a bathroom) or to different floors of a residence or office building. In some instances, water flow sensors in addition to the flow sensor 2505 on the main water line 2510 may be present on water pipes to different areas of the building, for example, water-flow sensors 2550, 2555, 2560 on or in water pipes 2525, 2565, 2570 delivering water to building areas 2515, 2540, 2545, respectively. These additional flow sensors may be installed in a building to, for example, provide for separate water utility billing to different residents or tenants of different areas of the building 2500.
As discussed above, the base units S may monitor local environmental conditions such as temperature, humidity, or the presence of liquid water in the room or area in which they are located. The base units S may additionally or alternatively monitor data regarding flow rate, water temperature, water pressure, and so forth in water pipes servicing the room or area in which they are located. The base units S may utilize the information regarding the local environmental parameters and data regarding flow rate, water temperature, water pressure, and so forth to determine if a water leak may be present in the respective rooms or building areas. A
base unit S may also be used to verify or confirm the presence of a water leak in an environment local to the base unit. For example, if water flow through pipe 2525, as measured by flow sensor 2550, increases unexpectedly one may suspect that the unexpected increase in water flow may be due to a leak in the pipe 2525 at the water delivery location for this pipe, room or area 2515. The base unit S in room or area 2515 may monitor local environmental conditions such as temperature, humidity, or the presence of liquid water in room or area 2515 to verify or rule out the presence of a water leak in room or area 2515.

Water pipes may sometimes develop leaks prior to their termination points. For example, water pipe 2525 in FIG. 25 may develop a leak in a portion of the pipe passing through room or area 2535 rather than at its termination point in room or area 2515. In one example, if water flow through pipe 2525, as measured by flow sensor 2550, increases unexpectedly, and the base unit S in room or area 2535 detects a local change in temperature consistent with a water leak, an increase in humidity, or the presence of liquid water, this may serve as an indication that the water leak is occurring in room or area 2535, rather than in room or area 2515.
In some embodiments, as discussed further below, a base unit S may operate in a low-power mode of operation, for example, by powering down or not actively monitoring its temperature, humidity, or liquid water sensors until a water flow rate in a water pipe leading to or passing through a room or area in which the base unit S is present changes in a manner consistent with a leak occurring somewhere along the length of the pipe.
Responsive to the water flow rate through the pipe being indicative of a possible water leak, the base unit S may power on or begin or resume active monitoring of its leak detection sensors to confirm or rule out the presence of a water leak in its local environment. In some examples, the base unit S may only be partially powered down, and some components of the base unit S (for example, components configured to determine whether a leak may be present) may remain fully or partially operational. In some examples, one or more of the sensors 2505, 2550, 2555, 2560 may be configured to awaken the base unit S from a low-powered or powered-down mode of operation responsive to sensing information that may be indicative of a leak.
Water-flow sensors that may be utilized in aspects and embodiments disclosed herein are not limited to any one type of flow sensor. The flow sensors may be ultrasonic sensors that clamp onto the outside of a water pipe or may be paddle wheel or other forms of sensors that are disposed at least partially within a water pipe to measure the flow of water through the water pipe. The flow sensors may output a signal indicative of measured water flow via wires to an external location or may communicate signals indicative of measured water flow to an external location wirelessly, for example, via a cellular or Wi-Fi signal. Also, although water flow sensors are indicated as downstream of associated water flow control valves in FIG. 25, the water flow sensors may additionally or alternatively be located upstream of the associated water control valves.

The problem of identifying a location of a water leak in a building may be exacerbated if the water leak is occurring in an area that is not easily visually inspected, for example, in a wall or beneath a floor. The problem of identifying the location of water leak may also be exacerbated if a building is not occupied when an unexpected increase in water flow through a pipe of the building is identified, for example, in a building undergoing construction if the leak occurs off-shift.
Aspects and embodiments disclosed herein include systems and methods to determine if an unexpected flow of water through one or more water pipes in a building that is indicative of a possible water leak occurs. A peripheral-sensor network may include one or more sensors distributed throughout different areas of the building that may be able to detect or confirm the presence of a water leak by measurements of, for example, changes in humidity, changes in temperature, or changes in conductivity between electrodes of a water-contact sensor. The one or more sensors may be included in base units as described in further detail below, and the peripheral-sensor network may include a plurality of base units. The peripheral-sensor network may also include sensors that are permanently embedded in building structures, for example, within walls, floors, or water pipes in a building.
A control unit or analytical engine, which may be centralized or distributed, and which may be located within or remote from the building, may monitor signals from one or more flow meters and/or pressure or temperature monitors coupled to or disposed within one or more water pipes in the building, as well as signals from one or more distributed leak sensors to detect and pinpoint the location of a water leak. For example, the server 04 discussed above may host and/or execute the analytical engine. The server 04 may be coupled to one or more of the base unit(s) 01, the external sensors 23, the external peripherals 30, and/or the external sensor arrays 424, and may further be coupled to one or more additional base units, sensors, peripherals, and/or sensor arrays. The control unit or analytical engine may automatically control one or more water valves to stop the leak and alert a responder of the leak so that the responder may repair or otherwise attend to the leak.
In some embodiments, one or more base units may be provided to form a sensor/monitor network for a water-leak-detection and mitigation system for a building. The base units (for example, the base unit[s] 01) may include interfaces to receive data from preinstalled water-flow sensors, temperature sensors, and/or leak detectors and/or to send commands to open or close water-flow-control valves. The base units may include functionality to measure signals output from a water-flow meter, either ultrasonic (clamp-on) or inline (invasive), and send data wirelessly over a cellular connection or over a low-power wide-area network (LPWAN) network or other form of wireless network to either a gateway or adjacent base unit.
The base units may include functionality to read outputs from water-flow meters including total flow, flow rate, water-pipe temperature, and ambient temperature. The base units may include functionality to output an electrical or wireless signal, either through wires or wirelessly, that can control an electric water-flow valve or pump to stop or enable water flow through a pipe that the water-flow valve or pump is installed on or in. The base units may include functionality to accept signals from a cloud-based software platform to open or close a water valve or control a water pump that it is paired with (via a wired or wireless communications connection).
In some embodiments, the base units may include or be in communication with water-pressure sensors that measure water pressure within different water pipes in a building. The water-pressure sensors may be disposed within the different water pipes at various locations in the building. Measured water pressures may be recorded and analyzed by the base units and/or communicated to a control unit or analytical engine in communication with the base units for recordation and analysis. The monitoring solution disclosed herein may provide an indication of a possible water leak responsive to detecting a reduction in water pressure within a pipe or may utilize measurements of water pressure to increase or decrease a confidence level regarding the presence of a water leak that was suspected based on measurements from one or more other sensors. For example, if a leak was suspected to be present in a pipe based on an increase in humidity or decrease in temperature at a location proximate the pipe, a water pressure sensor in the pipe could be used by a base unit to check if there was a drop in water pressure consistent with a leak and, if so, increase a confidence level regarding the leak being present.
The water pressure sensor may also or alternatively be utilized by the disclosed monitoring system to check that water pressure within pipes in a building are within acceptable limits. In some embodiments, a lower limit may be set for water pressure in pipes leading to, for example, fire sprinklers. A base unit or control system or analytical engine monitoring the water pressure in such pipes may issue a warning or automatically increase the water pressure by controlling one or more water pumps or valves if the water pressure dropped to a level at which the functionality of the fire sprinklers may be compromised. An upper limit may also be set for water pressure in one or more pipes in a building. An overpressure condition may be undesirable because the overpressure could possibly damage a water pipe or a system to which the water pipe is connected. A transient overpressure condition may be indicative of a water hammer and possible damage to an upstream water pump. Pressures higher than normal or outside an acceptable limit may be indicative of water in a pipe freezing. A base unit (or control unit or analytical engine) may thus issue a warning responsive to the pressure within a pipe being outside an expected or predetermined range. Monitoring of water pressure within pipes of a building may also reduce energy and system costs for maintenance, for example, by using measured water pressure as an input parameter to a controller that can decrease water pump speed or close one or more valves to keep the water pressure at a level that would not be expected to damage components of the building water system while still providing sufficient water pressure to operate the different water system components.
In some aspects and embodiments, installation of a water-leak-detection and mitigation system as disclosed herein may include installation of water-flow meters in one or more selected water pipes of a building. The flow meters may include functionality for measuring water temperature and pressure within the water pipes. Alternatively, separate water-temperature and/or pressure sensors may be installed on or in the water pipes. The flow meters may be invasive (having portions inside the water pipes) or non-invasive, for example, ultrasonic flowmeters that clamp around a water pipe. In some examples, the flow meters may be installed during construction for use as a permanent system during a lifecycle of a building. In other examples, non-invasive flow meters may be installed on water pipes during building construction, utilized for water leak detection/mitigation during building construction, and removed after building completion. In further examples, non-invasive flow meters may be installed on water pipes in a completed building during active building occupation to obviate the need for cutting water pipes, for example, a main water pipe of the building and interrupting service to the building.
The base units may be AC wall powered and include battery backup to continue monitoring during power outages or interruptions. In the event of a power failure, the base units may send power information to an external system, for example, a cloud-based platform. The external system may determine if there is a potential for the battery backup to be depleted and if so, may schedule replacement or recharging of the battery backup of a base unit.

The base units may include enclosures designed for durability and environmental exposures found in maintenance spaces and construction environments.
In some embodiments, the base units may include interfaces to receive information regarding water flow rate and/or water temperature, and/or water pressure for water flowing through one or more water pipes from one or more sensors disposed on or in the water pipes.
One or more base units may also include additional internal or external sensors, for example, humidity, ambient-temperature, or liquid-water sensors to monitor the environment local to the one or more base units for indicia of a water leak and to communicate this environmental information to other base units or to a centralized monitor/control system. In other embodiments, some base units may be dedicated water-flow base units which are dedicated to monitoring or receiving and passing on information regarding water-flow rate and/or water temperature, and/or water pressure for water flowing through one or more water pipes from one or more sensors disposed on or in the water pipes. Additional base units peripheral to these water-flow base units may be provided which can sense temperature and humidity and/or detect the physical presence of water through contact of the water with the additional base units' respective probes.
One or more base units or a control system/analytical engine in communication with one or more base units may totalize and record total water flow into a building or into different portions of a building over different time periods, for example, over a day, a week, or a month.
This data may be used to compare against utility readings and may be used to flag instances of a utility misreading water flow to the building or a portion of the building and mischarging an owner or tenant for the water provided. The flow rate through one or more pipes may be monitored and analyzed by one or more base units or a control system/analytical engine in communication with one or more base units to determine statistical measures associated with the water flow readings through one or more pipes, for example, average water flow, maximum water flow, minimum water flow, range of water flow, etc. The measures may be compared against expected water flows through the one or more pipes to determine if there is a deviation from the expected measures that may be indicative of a water leak, a clogged pipe, or a pipe being incorrectly connected to water-consuming equipment in the building.
One or more base units or a control system/analytical engine in communication with one or more base units may monitor and possibly record historical data for temperature of water flowing through one or more pipes in a building or of the pipes themselves.
The measured temperatures may be compared against expected temperatures or against defined ranges to determine if any conditions of concern may be present. Temperatures approaching freezing, for example, may be of concern due to the risk of water in a pipe freezing and possibly bursting the pipe. Temperatures above a desired level may be of concern due to the potential for the water to scald a user, for example, if a pipe in which the high temperature was measured is used to deliver water to a sink or shower. Temperatures above a desired level may also be of concern due to the potential for the overheated water to damage a component of the water system of the building. A
measurement of pipe temperature or of water temperature in pipes being outside a desired range may cause a base unit or a control system/analytical engine of embodiments of the system disclosed herein to issue a warning such that a responder may be alerted to the undesired water temperature and take measures to address it. The base unit or a control system/analytical engine of embodiments of the system disclosed herein may also include functionality to address undesired temperatures in one or more pipes, for example, by modulating power to one or more pipe heaters if present, by changing a mixture of hot and cold water delivered to a pipe, or by altering a flow rate of water through a pipe.
Implementations of base units or a control system/analytical engine in communication with one or more base units in systems disclosed herein may monitor and optionally maintain a record of one or more parameters related to water quality of water flowing into a building or through one or more pipes in a building with one or more sensors disposed within or about one or more pipes in or leading to the building. The parameters may include any one or more of turbidity, pH, conductivity, oxidation-reduction potential, or concentration of one or more chemical species. If one or more water-quality parameters drop below a desired or preset level this may be cause for concern if, for example, the pipe or pipes in which the undesirable water quality parameter is measured is used to supply water for drinking or one or more other purposes for which high-quality water is desired. A drop in one or more water-quality parameters may be indicative of a leak in one or more pipes allowing one or more undesired substances into the one or more pipes, may be indicative of a water pump or valve beginning to fail and shed substances into the water passing through it, or may be indicative of a problem with a utility supplying water to a building. Responsive to detecting a change in one or more monitored water quality parameters or responsive to detecting that the one or more water-quality parameters have dropped below a desired level, implementations of base units or a control system/analytical engine in communication with one or more base units in systems disclosed herein may issue a warning to a responder such that the responder may address the problem. The base units or control system/analytical engine may additionally control one or more water pumps or valves to shut off flow of the low-quality water to one or more points of use if desired, or control the one or more pumps or valves to reroute higher-quality water to the one or more points of use.
A water-leak-detection and mitigation system as disclosed herein may include a cloud-based software platform that collects data from all base units in the system.
The software platform may include a user interface that allows users to view real-time or historical data and send commands to open/close valves, overriding automated decisions made by the system. The system may provide manual and remote control over turning a water valve ON or OFF via the user interface.
The cloud-based software platform, or, additionally or alternatively, software resident on one or more base units in a water-leak-detection and mitigation system as disclosed herein may include an analytics engine that can detect patterns and baseline readings to determine water-leak events based on a water-flow-usage signature of a building in which the system is installed.
The analytics engine may correlate fluctuations in humidity or temperature at a location in a building measured by a base unit with changes in water flow rate through a water pipe servicing the building location to determine if a water leak is likely occurring. Responsive to determining that a water leak is likely occurring the analytics system may send an alert to a manager of the system, an owner of the building, or other responder with an indication of the likelihood of the water leak and the most likely location of the leak. The analytics engine may also determine which, if available, water valve is nearest to the leak to shut off water flow to the leak area. The analytics engine may automatically turn off the identified water valve responsive to the determination that a water leak is likely occurring and/or may send an indication of the identified water valve along with the alert. The alert or other messages may be sent by the analytics engine to users via web platform, phone application, SMS, email, or phone call, or to a response center associated with the system.
In some embodiments, alerts may be configured to be sent based on water flow during certain hours of the day, may be configured to be sent based on user settings, or may be configured to be sent based on patterns and analytics the system developed from prior data from a building it is installed in and/or data from other buildings or sites. In some embodiments, alerts may be sent when a flow meter falls offline or loses power.
Example 1:
The following is an example of the monitoring system operating in accordance with a preferred embodiment of the present disclosure.
A construction site consisting of a basement and several above-ground floors is outfitted with a plurality of base units 01. A number of areas within the site contain magnetically active metal structures and, in those areas, base units 01 are removably affixed to the structures using magnet mounts 360. In other areas, base units 01 are removable affixed to 2 x 4 pieces of wood via mounting straps 1371. A wireless networking gateway 32 is disposed near the spatial center of the site and allows the base units to wirelessly connect via LPWAN to the gateway 32 and provides access to a cellular data connection over 3G or 4G. The server 04 is hosted on the Internet and may be accessed using the cellular data connection.
The controller 18 in each base unit 01 executes a series of instructions corresponding to the method of networking configuration 1000 in order to determine their mode of operation. A
number of wireless repeaters are also installed around the site in order to extend the range of the gateway 32. Some base units cannot connect directly to the gateway 32 and instead connect to the gateway via one of the repeaters. Several other base units 01 cannot connect to either a gateway or repeater, but can connect to another base unit acting as a unit qualified to control a local network 01 as depicted in FIG. 10. If the base unit qualified to control the local network 01 is connected to the gateway 32 or a repeater, then the additional base units 01 connected to it may access the cellular network indirectly through the qualified base unit 01.
Otherwise, the local network of base units 01 may operate in an offline mode temporarily until an outside connection becomes available.
A software platform running on the server 04 collects and analyzes data from the connected base units 01 and any external sensors 23, external sensor arrays 424, or other peripherals 30 connected to any of the base units 01. The software platform performs acts 1100 or 1200 followed by act 900 to determine which types of events and/or preliminary events the system is configured to detect at the site being monitored. While performing act 900, a number of temperature sensors in a particular zone plus data from an external weather sensor array 424 indicate sub-freezing outdoor temperatures for the next several hours. Based on these readings, it is determined that a preliminary event corresponding to a potential frozen and/or bursting water pipe is in progress. Action 918 is performed, notifying necessary personnel of the potential for a pipe freezing over the next several hours, and sending a communication to one of the nearby base units 01 connected via external peripheral 30 to control a temporary heat source to raise the heat setting of the temporary heat source. Base unit 01 is further instructed to perform action 920, changing the mode of operation of several sensors including the temperature and humidity sensor to take measurements more often and transmit at a higher frequency, and turns ON a PIR sensor to begin looking for detectable temperature profiles.
Several hours later, the software platform running on the server 04 detects that a suspected event of a burst pipe (act 922) is causing an ongoing water leak upon analysis (act 912) of another base unit's 01 sensor data and despite the aforementioned efforts to prevent and/or delay the event by raising the heat. Act 914 is invoked, sending an alert to necessary personnel with details of the location, time, type, and severity of the event.
Personnel may respond and fully contain the event a short duration thereafter.
The software platform running on the server 04 continuously, at discrete intervals, or in response to various conditions performs methods 900, 1100, 1200, and/or 1600 and their constituent acts. Once the system detects that the event has concluded during the next cycle, the system generates a report detailing the duration, type, location, and severity of the event including the identities of those who received notifications and/or alerts.
Separate reports highlighting other parameters may be generated for other entities including insurance providers, owners, or subcontractors. Analysis of reports may provide suggestions for better deployment of detection and response measures, such the location of sensor and peripheral placement. For example, the analysis may enhance the placement of fans and/or temporary heaters for achieving more controlled heat dispersion throughout the building.
Example 2:
The following is an example of the monitoring system operating in accordance with a preferred embodiment of the present disclosure.
A construction project within or adjacent to an active hospital consisting of an area where there is access for entry or exit between the construction project and the active hospital is outfitted with a plurality of base units 01. Base units 01 are removably affixed to both sides of the entryway with one base unit 01 removably affixed within the active hospital side of the entryway and another base unit 01 removably affixed within the construction project side of the entryway. Base units 01 may be removably affixed at the same height from the floor to ensure accurate barometric pressure readings. A wireless networking gateway 32 is disposed near the spatial center of the site and allows the base units to wireles sly connect via LPWAN to the gateway 32 and provides access to a cellular data connection over 3G or 4G.
The server 04 is hosted on the Internet and may be accessed using the cellular data connection.
Alternatively, one of the base units 01 may be wirelessly connected to the server 04 using LPWAN
communication through gateway 32 and this base unit 01 wirelessly communicates with the base unit 01 on the opposite side of the entry way using a Bluetooth network. Alternatively, base units 01 may communicate using a wired connection.
A software platform running on the server 04 collects and analyzes data from the connected base units 01 and any external sensors 23, external sensor arrays 424, or other peripherals 30 connected to any of the base units 01. The software platform performs methods 1100 or 1200 followed by method 900 to determine which types of events and/or preliminary events the system is configured to detect at the site being monitored. While performing method 900, a difference in barometric pressure readings between the two base units 01 placed on either side of the entry way indicates that a preferred pressure differential is not being achieved. At this time, action 918 is performed, notifying necessary personnel of the failure to maintain the preferred pressure differential. Alternatively, while performing method 900 a difference in barometric pressure readings between the two base units 01 placed on either side of the entry way indicates that a preferred pressure differential is not being achieved indicating a preliminary event corresponding to a lack of negative air pressure over a prolonged period of time. After performing a time-based analysis, it is determined that a preferred pressure differential was not achieved for a previously selected period of time. At this time, action 918 is performed, notifying necessary personnel of the failure to maintain the preferred pressure differential over the previously selected period of time.
A visual display may be removably affixed to both sides of the entryway monitored by base units 01 where one visual display is removably affixed within the active hospital side of the entryway and another visual display is removably affixed within the construction project side of the entry way. Each visual display wirelessly communicates with the server 04.
Alternatively, each visual display may wirelessly communicate with the base units 01.
Alternatively, each visual display may communicate with a base unit 01 using a wired connection.
The wireless communication used may be cellular, Bluetooth, RF, and/or low-power wide-area network (LPWAN). One or both of the visual displays may indicate the current pressure differential, whether a preferred pressure differential is currently being achieved or not, a historical log of the pressure differential, the current measurement of dust, the presence of dust exceeding a preferred limit, the current noise level, whether the noise is currently exceeding a preferred noise level, and/or a historical log of any conditions or exceeded thresholds correlating to any of the plurality of sensors contained within the base unit(s) 01.
If a preferred pressure differential is not being achieved, the presence of dust exceeds a preferred limit, the current noise level exceeds a preferred limit, and/or the noise level exceeds a preferred limit a predetermined amount of times within a predetermined amount of time act 914 is invoked, sending an alert to necessary personnel with details of the location, time, type, and severity of the event. Personnel may respond and fully contain the event a short duration thereafter.
The software platform running on the server 04 continuously, at discrete intervals, or in response to various conditions performs methods 900, 1100, 1200, and/or 1600 and their constituent acts. Once the system detects that the event has concluded during the next cycle, the system generates a report detailing the duration, type, location, and severity of the event including the identities of those who received notifications and/or alerts.
The software platform running on the server 04 may generate reports which detail the recorded information collected from base units 01 and visual displays removably affixed to both sides of the entryway. Reports may be generated and sent to involved parties in real-time.
Alternatively, reports may be generated post event detection and include an analysis of one or more occurrences.
Separate reports highlighting other parameters may be generated for other entities including insurance providers, owners, or subcontractors. Analysis of reports may provide suggestions for better deployment of detection, response, and prevention measures. For example, the analysis may enhance the processes used to achieve a barrier between the active hospital and the construction renovation.

The software platform running on the server 04 may communicate with a building HVAC
system or BMS (Building Management System). Communication may occur wirelessly or through a wired connection. The wireless communication used may be cellular, Bluetooth, RF, and/or low-power wide-area network (LPWAN). While performing act 900, a difference in barometric pressure readings between the two base units 01 placed on either side of the entry way indicates that a preferred pressure differential is not being achieved.
The software platform running on the server 04 may communicate with building HVAC system or BMS to adjust the configuration of the building HVAC system or BMS system to prevent the preferred pressure differential from deviating from preferred levels. Alternatively, the software platform running on the server 04 may communicate with building HVAC system or BMS to adjust the configuration of the building HVAC system or BMS system to return pressure differentials to preferred levels.
Having thus described several aspects of at least one embodiment of this invention, it is to be appreciated various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure, and are intended to be within the spirit and scope of the invention.
Accordingly, the foregoing description and drawings are by way of example only.
