Description

A SYSTEM AND METHOD FOR TOILET ROOM MANAGEMENT

EMPLOYING loT SENSORS

TECHNICAL CONTRIBUTION

The present disclosure relates to toilet room maintenance. More particularly, the present disclosure relates to a toilet room management system and method employing loT sensor devices.

BACKGROUND

Sanitary ware toilet products and equipment like water taps, urinals, water closets, soap dispensers, hand dryers, toilet paper roll dispensers and other toilet products operate independently. These devices are typically not connected to any network and thus do not provide any electronic feedback or status information to the cleaning staff and technician staff who service the toilet rooms. The task of cleaning, diagnosing, inspecting, and replenishing dispensable items like soap, toilet paper rolls or paper towels are performed manually by the cleaning staff. Similarly, technician staff that repair the equipment must perform walk through inspections or otherwise be alerted by the cleaning staff to schedule repairs. As the consumption of consumables and the cleaning needs are not precisely known, maintenance of toilet rooms can be unpredictable leading to inconsistent results and high labor costs.

Whenever there is a fault or breakdown (e.g., water leaks, over running faucets, no flushing), the technicians are typically unaware until someone reports or complains about the problem. The technicians are then deployed to identify and repair the faulty sanitary ware equipment. A system or method with real-time information and predictive capabilities is needed to better alert staff to any issue in the toilet rooms of a facility and immediately direct technician staff or cleaning staff to get to work on solving the faults. SUMMARY

A first embodiment of the invention is a toilet room management system for maintaining a plurality of toilet rooms by a staff comprising: (a) a plurality of IoT sensors configured to create sensor data for calculation of a consumption status for a plurality of consumables, an environmental status for each toilet room, and a traffic pattern for each toilet room; (b) a gateway configured to receive the sensor data from each of the IoT sensors; and (c) a server in communication with the gateway and at least one user interface through a network, wherein the server includes a database. The database includes: (i) an IoT description for each IoT sensor, wherein each IoT description includes a set of data attributes and a set of sensor parameters; (ii) an IoT inventory for each toilet room; (iii) a staff profile for each member of the staff; (iv) a time series archive of the sensor data for each of the plurality of toilet rooms; (v) at least one consumable replenishment schedule; and (vi) at least one maintenance schedule with a plurality of task items. The server is configured to: (i) store and collate the sensor data in the time series archive; (ii) generate a plurality of task items and a plurality of reports, wherein each task item includes a current task status; (iii) monitor in real time the IoT sensors and create a plurality of urgent maintenance alerts; (iv) recommend updates for the consumable replenishment schedule and the maintenance schedule; and (v) generate screen information for the user interfaces to present the task items, the reports, and the urgent maintenance alerts; and receive data input from the staff.

A second embodiment of the invention is a method of toilet room management employing IoT sensors comprising the steps of: (a) connecting to a gateway configured to receive sensor data from a plurality of IoT sensors, wherein the IoT sensors are configured to create sensor data; (b) providing a server in communication with the gateway and at least one user interface through a network, wherein the server includes a database; and (c) performing on the server the steps of: (i) calculating a consumption status for a plurality of consumables, an environmental status for each toilet room, and a traffic pattern for each toilet room; (ii) storing and collating the sensor data in the time series archive; (iii) generating a plurality of task items and a plurality of reports, wherein each task item includes a current task status; (iv) monitoring in real time the IoT sensors and create a plurality of urgent maintenance alerts; (v) recommending updates for the consumable replenishment schedule and the maintenance schedule; and (vi) generating screen information for the user interfaces to present the task items, the reports, and the urgent maintenance alerts, and also to receive data input from the staff.

Each IoT sensor can be in communication with the gateway 10 via at least one of a wireless transceiver and a wired link. Also communication between the IoT sensors, the gateway 10, the server 12, and the user interfaces 06 can be encrypted and at least one of the IoT sensors can be configured to receive at least one command from the server through the gateway.

The commands received by the at least one of the IoT sensors can be at le st one of a flush command, a water flow command, an alert signal, and a configuration command. The flush command, for instance, can be sent by the server to the urinal flush sensor to flush the urinal and/or to the water closet flush sensor to flush the water closet. The water flow command can be sent to the water tap sensor to start, stop, and/or pulse water flow through the water tap. The alert signal can be used to flash an LED and/or sound an audible signal to help alert and direct a member of the staff to repair, replace, maintain, and/or refill an item in one of the toilet rooms 01. The configuration command can be used to configure an IoT sensor with a level of specificity, a scheduled reporting frequency, and/or a sleep mode.

In addition, the gateway 10 can include at least one of: (a) a Wi-Fi Access Point to aggregate data packet transfer to and from the server 12; (b) a local area network; and (c) a NB-IoT or 3G SIM card based mobile communication network. The IoT sensors can also be conducted via a Message Queuing Telemetry Transport.

A Wi-Fi Access point is a wireless access point that allows a Wi-Fi device to connect to a wired network. It usually connects to a router (via a wired network) as a standalone device, but it can also be an integral component of the router itself.

NB-IoT refers to a low power WAN standard using a SIM to enable cellular devices and services. NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density. 3G is a widely available cell phone communication standard. Both NB-IoT or 3G can provide coverage for remote areas that do not have a wired telecommunications infrastructure,

Message Queuing Telemetry Transport) is an ISO standard publish-subscribe-based messaging protocol. It works on top of the TCP/IP protocol. It is designed for connections with remote locations where a small code footprint is required or the network bandwidth is limited.

The consumption status can be calculated from the sensor data of at least one of a soap dispenser sensor, a water tap sensor, a hand dryer watt meter, a toilet room watt meter, a toilet paper roll dispenser sensor, a paper towel sensor, a waste bin sensor, at least one urinal flush sensor, and at least one water closet flush sensor. The environmental status can be calculated from the sensor data of at least one of a temperature sensor, a humidity sensor, a sound level sensor, a smoke sensor, a smelt sensor, a water leak sensor, and an air quality sensor. The traffic pattern can be calculated from the sensor data of at least one of an RFID sensor, a people counter, at least one of the urinal flush sensors, and at least one of the water closet flush sensors. At least one smell sensor can be an ammonia sensor. Each urgent maintenance alert can be determined based upon at least one of the consumption status, the environmental status, the traffic pattern, and a loss of communication between the server 12 and one of the IoT sensors. Urgent maintenance alerts can be categorized by at least one of a water leak, an over running faucet, a flushing failure, a soap dispenser refill indication, a paper towel refill indication, and a toilet paper roll refill indication. The flushing failure can be caused, for instance, by insufficient water pressure, insufficient water flow, air in the water lines, and/or excessively high water pressure.

The server 12 can be further configured to employ Machine Learning or Artificial Intelligence (“AI”) programming to predict an emerging traffic trend and recommend changes for the consumable replenishment schedule and the maintenance schedule.

Machine Learning or AI, sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and other animals. Machine Learning or AI programs can mimic functions that humans associate with other human minds, such as learning and problem solving. Machine Learning or AI can be used by the server 12 to progressively improve the quality of service (“QoS”) on specific cleaning tasks, and predict future changes in the need for consumables, maintenance, and repair. For instance, if the occupancy of a toilet room 01 increases, the system 1-01 may predict the increased need for soap, paper towels, and toilet paper roll for that toilet room 01. For use in larger facilities, such as airports, Machine Learning or AI may also be used to connect to additional data outside the toilet room management system, such as upcoming passenger arrivals in an airport, to predict consumption and maintenance needs due to possible increase in usage.

The reports can include at least one of: (a) a consumption history including at least one of an energy consumption, a water consumption, a paper towel consumption, a waste bin usage, a toilet paper roll consumption, and a soap consumption, wherein the consumption history is calculated from the sensor data in the time series archive; (b) a building management summary indicating a cleaning status and a maintenance status for the toilet rooms 01; (c) a manpower management summary indicating at least one of a cleaning staff availability, a technician staff availability, a staff scheduling roster, a response time statistic, a staff attendance statistic, a staff efficiency statistic, and a plurality of staff substitution recommendations; (d) a performance index summary indicating at least one of a downtime metric, an equipment fault history, an index of cleanliness, and a traffic history; (e) a system status including each IoT sensor and the gateway 10; and (f) an occupancy of each toilet room 01 determined from the sensor data collected from the urinal flush sensors and the water closet flush sensor of each toilet room 01. Entries in the equipment fault history can include at least one of a unit identifier, a location, a fault frequency, and a type of fault. The server 12 can be configured to recommend to a user an alternate toilet room 01 based on the occupancy of each toilet room 01. The reports can be presented in at least one dashboard screen in each user interface 06.

Each user interface 06 can be configured to: (a) associate each task item with at least one member of the staff; (b) permit updating of the current task status of each task item; (c) record readings of at least one mobile sensor 05; and (d) record an adhoc cleaning. Each user interface 06 can be at least one of a portable tablet, a smart phone, a dedicated device, a laptop computer, or a desktop computer. Each staff profile can include a work location, a staff ID, a job designation, and a work schedule.

While various aspects and embodiments have been disclosed herein, it will be apparent that various other modifications and adaptations of the invention will be apparent to the person skilled in the art after reading the foregoing disclosure without departing from the spirit and scope of the invention and it is intended that all such modifications and adaptations come within the scope of the appended claims.
