Description

Industrial environment safety management system device {INDUSTRIAL ENVIROMENTAL SAFETY MANAGEMENT SYSTEM APPARATUS}

The present invention relates to monitoring and safety management of industrial sites, and more specifically, to an industrial environment safety management system device capable of creating a safe working environment by monitoring and paying attention to environmental conditions around industrial work sites. will be.

In general, the safety of each worker is required as the top priority in construction, civil engineering, and plant sites. However, until now, most of the safety of these workers has been conducted in advance, and in the case of being put into the actual work site, it is common for each individual to be in charge of safety by himself. Recently, due to the development of smart devices and wearable devices, some systems have been proposed that enable the central control server to check the location or body information of workers. However, since each system is equipped to adapt only to individual sites, it is impossible to apply to various environments. In addition, an environment in which field workers can respond immediately while accurately judging the situation remotely in real time has not been created. In cases where a disaster comes unexpectedly, such as a construction site, and rapid response is required in case of an accident, the above problem is pointed out as a limitation because it leads to serious human casualties.

On the other hand, most of the modern construction sites use concrete, and traditional pouring and curing methods continue to be applied. Curing of concrete refers to sufficient protection and management after concrete casting is completed so that it is not affected by temperature, load, impact, contamination, damage, etc. The strength and durability of concrete depend on the quality of curing after casting. It is safe to say that it is determined by Depending on the application of curing, time for hydration of cement is guaranteed and an environment that can reach the final compressive strength is created.

Such curing may be classified into wet curing, steam curing, electric curing, and film curing depending on the method. Usually, direct sunlight, cold weather, wind and rain are avoided, and moisture is maintained by spraying for a predetermined period (usually 5 days or more) by covering the mat or packaging to ensure hydration.

However, since heat preservation is also important during this curing, there is a limit to the work during the winter season. During the construction of concrete structures in the winter season, there is a problem in that the initial strength expression is excessively delayed due to exposure to an excessively low-temperature environment and exposure to frost damage in an unhardened state. In general, it is known that the curing temperature after pouring concrete should be maintained at 10 ° C to 20 ° C for 3 days, 5 ° C to 10 ° C for 3 to 4 days, and 0 ° C to 10 ° C for 4 to 7 days.

That is, in the construction of a concrete structure in the winter season, an imbalance in strength expression occurs for each part of the concrete structure according to an imbalance in curing temperature and a change in curing conditions, and durability is lowered. This causes problems of time delay and economic loss as well as quality problems due to inefficiency of curing management.

Recently, in order to prevent early frost damage in the winter season, a method of correcting the mixture of ready-mixed concrete or heating and insulating according to the curing temperature environment of the concrete structure is applied in order to prevent freezing until the concrete exhibits a predetermined compressive strength after concrete is poured.

In order to keep the curing environment warm as described above, a method using heat generated by burning lignite has been widely used. The application of the lignite boiler has the advantage of relatively low cost and sufficient heat generation, but since heat management is required, a worker periodically inputs and manages fuel. In order to solve this trouble, recently, a technology for controlling the temperature of the curing environment in winter has been proposed.

Korean Patent Publication No. 2002-0025575 discloses a conventional concrete curing temperature control method, and FIG. 1 is a configuration diagram thereof.

Looking at this in detail, a boiler 60 that provides an appropriate temperature to secure a predetermined quality during concrete curing, and a shield that is sealed and installed in the space around the construction to isolate the concrete structure 1 to be cured from the outside. The tent 40, internal and external temperature sensors 42 and 41 disposed at each part to sense the temperature of the shielded space and the outside thereof, and the internal and external temperature sensors 42 and 41 After analyzing the temperature of each part sensed by ), the controller 10 variably adjusts the temperature, and is installed between the internal and external temperature sensors 42 and 41 and the controller 10 to detect each temperature It has a configuration including a converter 20 that converts the temperature sensed by the sensors 41 and 42 into an electrical signal.

As described above, lignite or charcoal is used for heating and keeping the curing environment warm, and human accidents are constantly occurring due to toxic gases such as carbon monoxide generated thereby. Even in the case of the prior art, it is very difficult to prevent such human accidents because they stop at simple temperature sensing.

Furthermore, it is known that lignite or charcoal must be continuously replaced to maintain the temperature, and the rate of suffocation is rapidly increasing, especially during night shift work by watchmen.

However, since it is virtually impossible to add expensive safety measures equipment due to the rapidity and economic feasibility of the concrete pouring and curing environment, there is a demand for a technology that can guarantee safety throughout the industrial site and is actually applicable to construction companies. .

In addition, countermeasures capable of preventing heat-related illnesses in a high-temperature working environment are required.

In addition, it is necessary to respond to air pollution as well as worker safety problems due to fine dust generated in various industrial environments, and improvement of a system capable of performing complex functions by adapting to various environments is required.

The present invention has been made to overcome the problems of the prior art, an industrial environment safety management system device that can prevent safety accidents in advance at various industrial sites and maximize the efficiency of construction by creating a working environment. intended to provide

On the other hand, the control and maintenance determination unit may request adjustment by providing the location of the complex sensor unit with respect to the arrangement with the heat source in the pouring space as maintenance information.

The toxic determination unit determines that the toxic condition is satisfied when the gas value is equal to or higher than the set lower limit, and shares the information with other complex sensor units. The control and maintenance judgment part functions only in the complex sensor part, which functions to generate an alarm of access control for workers.

The management unit may transmit a control signal for controlling whether or not to spray or amount of atomization of the atomizing device when the measured concentration of fine dust is greater than or equal to a set concentration of fine dust, or may alarm when the thermal index is higher than the set index.

According to the present invention, safety accidents such as heat illness or suffocation can be prevented in advance by adapting to various industrial environments, and fine dust can be managed, thereby improving safety at industrial sites.

In addition, real-time status notification to workers and managers as well as active access control for workers is possible, so the safety of industrial sites is dramatically improved.

In addition, it is possible to perform functionalized operations by flexibly adapting to the wireless environment at various industrial site locations, and it is economical because the effort and cost for construction can be minimized, and the complex sensor units actively operate to control information Alternatively, since repair information can be provided to workers, the efficiency of the curing field can be dramatically improved.

* The complex sensor unit 1000 is installed at a selected location in a predetermined industrial environment to detect temperature, humidity, gas, and the presence or exit of a worker and perform a predetermined safety judgment. Let me tell you later.

The installation location of the complex sensor unit 1000 may be selected and placed on a ceiling or wall in consideration of the site under construction. It may also be considered to be fixed as .

In the illustrated embodiment, a case in which the display board and the gateway 2000 are combined and configured together is shown. The electronic signboard and gateway 2000 are composed of a combination of a display displaying predetermined set image information and a gateway to which a protocol for wireless remote communication is applied, but the display and the gateway do not necessarily have to be integrally configured.

A plurality of the complex sensor units 1000 are installed in various places in the industrial environment to collect information in a centralized manner and to immediately provide a predetermined alarm or notification to the site, and such a server unit 300 It can be understood as including various equipment including a predetermined storage and a microcom such as a PC, a management server, a base station, a smart phone, and a tablet PC.

In addition, as a preferred embodiment, the server unit 300 may be configured as a cloud server, and remotely converts sensed values by location and identifier corresponding to each complex sensor unit 1000 into data, stores and manages the function.

In the case of a general industrial site, unlike a completed building, wiring from a power source or communication network is not completely established. The connection of the unit 300 is preferably made in a wireless manner. For example, cases in which various wireless communication methods such as Zigbee, Bluetooth, RF communication, WiFi, 3G, 4G, LoRa (Long Range), and Cat.m1 communication are applied may be considered. However, a wired communication method is not excluded, and a wired communication method such as a wired LAN or RS485 Modbus may be applied.

In the illustrated embodiment, the composite sensor unit 1000 on one side is installed at a construction site, detects and monitors construction risk factors, and transmits them to the server unit 300, and the other composite sensor unit 1000 It can be installed at the construction site to detect and monitor fine dust and other hazardous factors.

The information generated by the complex sensor unit 1000 may be detected values for fine dust, ultrafine dust, temperature, humidity, carbon dioxide, carbon monoxide, nitrogen oxide, sulfide, ozone, formaldehyde, odor, occupancy, movement, and entry. In the case of the temporary construction site, it may also include information on ultrafine dust, temperature (related to heat illness), and work information that can be displayed on the electronic signboard and gateway 2000 for safety management guidelines. In addition, in the case of a completed site, it will be possible to monitor factors such as fine dust, ultra-fine dust, temperature, and humidity, but is not necessarily limited to the above example.

The industrial environment information stored and managed in the cloud server is transmitted in real time to a portable device 400 such as a smart phone or tablet PC carried by a worker, and remotely without relying on the electronic signboard and gateway 2000 monitoring will be possible.

The complex sensor unit 1000 can perform a function of notifying or controlling an external device according to a predetermined functionalized logic in a management unit through a detected value detected by a predetermined sensor module, and in this regard, the curing field A detailed description will be given in an embodiment related to management.

As a first embodiment of functionalization by the configuration of the complex sensor unit 1000 described above, the present invention presents a function capable of managing fine dust in an industrial environment.

At this time, as an external device, a system including a water body spraying device may be configured, and the complex sensor unit 1000 generates a control signal when the detection value of fine dust or ultrafine dust is higher than the set value, transmits the control signal to the spraying device, and sprays. It will be possible to control whether or not the amount of atomization is controlled to lower the concentration of fine dust. At this time, the spray device may include one or more of a nozzle, a water pump, a valve, and a tank.

In addition, as a second embodiment of functionalization by the configuration of the complex sensor unit 1000, the present invention performs a temperature management function to prevent heat-related illnesses in an industrial environment.

In this case, the complex sensor unit 1000 may be able to detect temperature as an index that can cause heat stroke, but since humidity and fine dust are factors that can affect heat illness, the detection value for functionalization of the management unit function as In this case, the complex sensor unit 1000 may display an alarm or step on the electronic display board and the gateway 2000 when the detected thermal index is higher than the set index, and recommend the worker to rest or evacuate.

3 is a block diagram of an industrial environment safety management system device according to a preferred embodiment of the present invention.

In this embodiment, a state in which predetermined spaces are partitioned by walls as an industrial environment is described, and a pouring space 200 is formed therein. In some cases, when the pouring space 200 is formed in an open form, it may be isolated from the outside to some extent by wrapping the outside with a tarpaulin or the like.

One or more heating sources 100a, b... may be disposed in the one or more partitioned spaces, the pouring space 200, to satisfy a predetermined curing temperature condition. The heat source may refer to a furnace in which lignite or charcoal used in a plurality of curing environments is accommodated, but may include various heating or blowing means such as a boiler and a hot air fan, and is not limited to the present embodiment.

The installation location of the complex sensor unit 1000 may be selected and placed on a ceiling or wall in consideration of the site under construction. It may also be considered to be fixed to and may be configured in combination with the above-described electronic display board.

The composite sensor unit 1000 may be accommodated inside a predetermined housing to protect electric elements such as internal sensors and substrates. The shape and size of the housing is optional. However, as will be described later, it is preferable to have a predetermined communication port for monitoring air quality according to a predetermined air flow.

In the case of industrial sites including construction sites, the wireless environment is suitable as described above. Considering the amount of information and the simplicity and economic feasibility of the configuration, it would be desirable to apply the LoRa communication method and gateway.

4 is a configuration diagram showing an embodiment of a complex sensor unit for functionalization of a curing field in the industrial environment safety management system device of the present invention.

The management unit 1400 and the sensor module 1200 mounted in the housing of the complex sensor unit 1000 may be mounted on a predetermined printed circuit board, and a PCB of a known technology may be applied to this, so a detailed description is omitted. let it do

The management unit 1400 may receive a detection signal from the sensor module 1200, perform a judgment for a set function, transmit an alarm signal, or provide guidance on the arrangement of a curing environment. The transmission of the alarm signal may mainly include notifying the outside of the judgment result on the appropriateness of the curing environment, determining the toxic gas condition harmful to the human body, and controlling the worker's access, and such a management unit 1400 A specific embodiment of the operation will be described later.

The sensing value for the curing environment received from the management unit 1400, the information on the situation determined by the management unit 1400, and the corresponding command are external equipment including the server unit 300 through the transmission/reception unit 1110. It can be mainly transmitted in a wireless manner to the field. Redundant descriptions regarding the communication method will be omitted.

In addition, due to the nature of the facility at the curing site, it can be driven with its own power source without supplying external power, and it is advantageous to be detachable and movable as needed, so a battery (not shown) can be additionally combined, and these batteries are also modularly mounted. case may be considered.

The transceiver 1110, the management unit 1400, and the sensor module 1200 can be installed according to a predetermined selected arrangement inside the housing, and can recognize the status or alarm or notification by the management unit 1400 from the outside. An audio output unit 1441 and/or an optical output unit 1442 may be provided to

The sound output unit 1441 may notify the user of information necessary for maintenance or a warning signal for a health environment or a toxic environment through a voice or alarm sound. The optical output unit 1442 may notify the user of power supply, operation status, and numerical values for environmental information in a color or flickering manner. In some cases, the optical output unit 1442 may be configured as a display capable of outputting an image.

The management unit 1400 basically performs judgment on the curing environment of the pouring space 200 and toxic conditions to the human body, and functionalizes information on the composition of the curing environment, proposals for monitoring the curing environment, notifications on access control, etc. action can be performed.

In the curing environment, temperature and humidity are basically judged as major factors, and in the case of toxic conditions, all gas concentrations that can be harmful to the human body can be factors. The concentration of carbon monoxide, which is the cause of many fatal accidents at curing sites, can be a determining factor for major toxic conditions. In addition, the concentration of fine dust can also be a factor in determining toxic conditions in light of harmfulness to the human body.

As a result of the determination of such toxic conditions, the provision of a predetermined notification may vary depending on the presence or absence of a worker or the presence of a person entering or leaving the room, so a determination of occupancy or entry may be added.

Figure 5 is a block diagram for explaining an embodiment of the sensor module in the industrial environment safety management system device of the present invention.

The complex sensor unit 1000 is composed of a plurality of sensors in the form of a module, and various types of sensors may be combined to perform functions selected by the management unit 1400 .

A temperature and humidity sensor 1211 may be provided to determine the curing environment, and the temperature and humidity sensor 1211 detects the temperature and / or humidity in the pouring space 200 and transmits the detected value to the management unit 1400.

In addition, a gas detection sensor 1212 may be included to determine the toxic environment, and the gas detection sensor 1212 is based on a CO sensor, but an O ₂ sensor, a CO ₂ sensor, and/or a PM (Particulate Matter) Sensors and/or formaldehyde sensors may be additionally or interchangeably arranged. In the case of the PM sensor, for example, sensors capable of measuring particles of different sizes (PM10, PM2.5, PM1.0, etc.) may be combined.

In addition, a fire sensor 1214 may be additionally disposed to manage a fire caused by lignite or charcoal in the pouring space 200, and the fire sensor 1214 may be a heat sensor or a smoke sensor, but is necessarily limited thereto It is not, and various sensors for known fire detection may be applied.

In addition, an entry/exit detection sensor 1213 may be included, and the entry/exit detection sensor 1213 may detect an operator's entry/exit or occupancy at a predetermined entrance/exit and transmit a detection value to the management unit 1400. The entrance/exit detection sensor 1213 may be, for example, a PIR (Passive Infra-Red) sensor.

In addition, the sensor module 1200 may include one or more of a microphone for sound input and/or a vibration sensor for detecting vibration.

Meanwhile, it may be considered that a fan module actively forming a flow is applied to a predetermined through-hole in the housing to guide the inflow and outflow of air.

The sensor module 1200 may be installed on a substrate together with the management unit 1400, and may have a pin or terminal for connectivity so that each sensor device can be selectively mounted.

Figure 6 is a block diagram for explaining an embodiment of the management unit for functionalization operation in the industrial environment safety management system device of the present invention.

The management unit 1400 determines the basic environment or condition based on the detection signal transmitted from each sensor of the sensor module 1200, and through this, it can operate with individualized and optimized functions. To this end, the management unit of the present invention may be configured to include logic that immediately adapts to the environment or works in conjunction with an external artificial intelligence server.

A curing condition determination unit 1411 for collecting state information of the curing environment may be configured. The curing condition determination unit 1411 determines the appropriateness of the curing environment through the temperature detection value and/or humidity detection value collected from the temperature and humidity sensor 1211 and informs the worker through the control and maintenance determination unit 1414. You will be able to perform notifications. As described above, different temperature conditions may be required for each seal after concrete pouring, and the curing condition determination unit 1411 determines the appropriateness of the curing environment for each lapse of time from the set time, and the server unit including the user's smartphone, etc. ( 300) will be able to perform guidance. When the control and maintenance determination unit 1414 determines that the temperature of the predetermined pouring space 200 is lower than the set lower limit value, it determines that the heating source 100 has insufficient heat or is turned off, and informs the server unit 300 of it. Alternatively, maintenance information for replenishment of lignite or the like may be notified to the operator through the alarm unit 1440.

In addition, including the toxicity determination unit 1412, it may perform a function of determining factors that may pose a safety hazard to workers. The toxicity determination unit 1412 may make a decision based on the detected value of the gas detection sensor 1212. For example, when the gas detection sensor 1212 is made of a CO sensor, the lower limit of the carbon monoxide concentration is set as a set value. Therefore, when the concentration signal from the gas detection sensor 1212 is higher than this, it can be determined that the toxic condition is satisfied. Depending on the determination result of the toxicity determination unit 1412, the control and maintenance determination unit 1414 may transmit alarm control information through the alarm unit 1440 so as to restrict access of visitors. In addition, the server unit 300 may perform a function of transmitting maintenance information on the need for ventilation in a toxic situation or the need for reorganization of the pouring space 200 .

According to the determination result of the toxicity determination unit 1412, the control and maintenance determination unit 1414 may issue an alarm through the alarm unit 1440 according to whether an occupant is in the room or whether a person enters or leaves the room. If an alarm such as sound is continuously generated by satisfying the toxic condition, a problem of power shortage may occur, especially in a battery operated situation. Therefore, it is also preferable to send an alarm to the complex sensor unit 1000 adjacent to the entrance only when the entry/exit detection sensor 1213 detects a situation in which a worker enters after determining the toxic condition in the toxicity determination unit 1412. In this case, a connection between complex sensor units 1000 disposed in the same pouring space 200 or a connection between grouped complex sensor units 1000 of one server unit 300 is required, and this connection relationship is an implementation for mesh connection. It will be described later in an example.

CO concentration, CO ₂ concentration, formaldehyde concentration, fine dust concentration, etc. may be involved in the determination of toxic conditions by the toxicity determination unit 1412.

In addition, a fire determination unit 1413 may be further included, and a fire detection signal may be received from the sensor module 1200 to determine whether there is a fire or a dangerous situation. Basically, the detection signal of the smoke detection sensor can function as a major factor in determining a fire. In order to compensate for this, a detection value related to gas or a detection value related to particles can be used to determine a fire.

The control and maintenance determination unit 1414 may perform a function of informing workers of access control information or maintenance information, and in some cases may perform a function of transmitting an operation control signal to an external device. For example, when the internal gas concentration is high, a function of forcibly closing the entrance by transmitting an operation signal to a locking means provided on the entrance door may be considered.

As described above, the control and maintenance determination unit 1414, as an embodiment, can function to transmit an alarm signal to the complex sensor unit 1000 adjacent to the entrance according to the presence or absence of visitors, and by this concept, the entry/exit detection sensor ( The detection signal of 1213) can be used as a factor for determining whether there is a person in the room or whether there is a person entering or not in the control and maintenance determination unit 1414.

In addition, the alarm unit 1440 may perform a function of transmitting an alarm signal from the complex sensor unit 1000 at an appropriate location through the sound output unit 1441 or the light output unit 1442.

On the other hand, in the present invention, it is as described above that the composite sensor unit 1000 is disposed in a plurality of selected locations of the pouring space 200 and is wirelessly connected to the server unit 300, respectively. The arrangement of each complex sensor unit 1000 can be basically based on the location of the heat source 100, but due to the nature of the curing site, when there is a lot of equipment, when it is partitioned by a wall, it is difficult to place it in an appropriate position due to the poured concrete. There may be restrictions such as difficult cases. In consideration of this, it is preferable to provide a tracking unit 1420, determine the positional relationship of each complex sensor unit 1000 with each other, and transmit maintenance information for an appropriate location. A specific embodiment for this will be described later.

Figure 7 is a block diagram for explaining an embodiment of the tracking unit in the industrial environment safety management system device of the present invention, Figure 8 is a view for explaining the arrangement of a plurality of composite sensors in the pouring space.

In the illustrated embodiment, four heat sources are disposed in the entire pouring space. A fourth complex sensor unit 1000d is disposed adjacent to the entrance and facing the fourth heat source 100d, and a third complex sensor unit 1000c is disposed between the indoor door and the third heat source 100c. , The second complex sensor unit 1000b is disposed at the corner facing the second heat source 100b, and the first complex sensor unit 1000a is disposed adjacent to the first heat source 100a in the small room. However, the above arrangement state is an example and can be applied in various ways for each construction environment.

In the concept of the present invention, each complex sensor unit is connected to the server unit 300 through a wireless connection method, and individual connections can be made so that information can be exchanged with each other. Accordingly, the tracking unit 1420 includes a mesh connection unit 1421, and the mesh connection unit 1421 has a connection relationship with adjacent complex sensor units.

This mesh connection unit 1421 may constitute a one-stage connection relationship or a multi-stage connection relationship. Here, the multi-stage connection relationship means that a complex sensor unit that is connected only from one complex sensor unit to another complex sensor unit connects another complex sensor. means to connect via This multi-stage connection relationship will be meaningful when there are complex sensor units whose structure is complex or wide and does not receive radio waves smoothly.

When installed in a curing environment, each of the complex sensor units can be identified by detecting signals from each other according to the operation of the mesh connection unit 1421, and each of the complex sensor units 1000a, b, c, and d are individually An identifier may be assigned.

The sensitivity determination unit 1422 may determine connectivity between the complex sensor units 1000a, b, c, and d having respective identifier signals, and if the signal is weak, a multi-stage (partial) mesh network may be established. configuration to enhance connectivity.

The mapping unit 1423 calculates the distance according to the identifiers and signal sensitivities of each of the complex sensor units 1000a, b, c, and d, and constructs a map of the arrangement based on the triangulation result of the measurement unit 1424. . A plurality of complex sensor units 1000a, b, c, and d may share this map.

There may be a case where the composite sensor units are configured to be adjacent to each heat source and a case where they are separated from each other, and temperature and/or humidity may appear different from each other according to a distance relationship. Depending on the intensity of this temperature, a distance relationship with a heat source may also be mapped.

On the other hand, for example, if the temperature of a specific location in the tracking unit 1420 is too low, it is judged that the arrangement of the heating source is not appropriate or the sensing location of the complex sensor unit is not appropriate, and the operator is informed through the control and maintenance determination unit 1414. Adjustment may be requested by providing the location of the heat source or the location of the corresponding complex sensor unit as maintenance information.

On the other hand, when the mesh connection is configured as described above, for example, carbon monoxide is excessively generated due to incomplete combustion in the first heating source 100a, and the toxicity determination unit 1412 of the first complex sensor unit 1000a generates a toxic condition. When it is determined that the condition satisfies, this situation may be shared with other composite sensor units 1000b, c, and d. When it is determined that these toxic conditions are satisfied and entry and exit is detected in the fourth complex sensor unit 1000d on the entrance side, the control and maintenance judgment unit 1414 of the fourth complex sensor unit 1000d transmits control information and The alarm unit 1440 may generate a buzzer or voice alarm to control access. In addition, maintenance information may be transmitted to the server unit 300 to allow workers to ventilate or replace fuel. In this case, the dangerous area may be specifically notified by voice while tracking the worker in an adjacent complex sensor unit through motion detection according to the movement path of the person.

As described above, by the industrial environment safety management system device of the present invention, it is possible to prevent safety accidents such as heat illness or suffocation in advance by adapting to various industrial environments, and to manage fine dust, thereby improving industrial safety. has the effect of

In addition, since real-time status notification to workers and managers as well as active access control for workers is possible, the safety of industrial sites is dramatically improved.

In addition, it is efficient because it is possible to perform functionalized operations by flexibly adapting to the location of various industrial sites by wireless environment, and it is economical because the effort and cost for construction can be minimized.

In addition, the complex sensor units can actively operate to provide control information or maintenance information to workers, so that the construction efficiency of the curing site can be dramatically improved.
