This article discusses the fire water supply facilities mainly refers to the fire pump (spray pump, fire hydrant, regulator pump) water supply and high fire water tanks and fire pool water. At this stage, the overall fire-fighting water supply facilities are relatively good. The construction unit can be installed and constructed in accordance with national standards. The unit or management unit can strengthen the maintenance and management of the fire-fighting facilities and keep the fire-fighting facilities in a good state of operation. Played an important role. However, some units of fire-fighting facilities, especially the maintenance and management of fire-fighting water supply facilities, lack strict scientific management. Usually, high-level water tank automatic recharging pumps and inlet valves of fire fighting pools are closed, and automatic water supply and full water levels cannot be maintained. Fire pumps occur during fires. Failure to start the pump properly caused the fire to spread and cause serious consequences. The key problem here is that the fire management methods of some units are simple and technically backward. They still follow old-fashioned practices and rely on manual inspections to check the operation status of each part and each equipment. There are many uncertainties and poor results. Many problems need continuous improvement and improvement, and actively use the Internet of Things technology to change the unstable and unreliable conditions of fire-fighting water supply facilities.
1 main problems in fire water supply facilities
Fire-fighting water supply facilities are the key equipment for the unit's fire-fighting facilities, and play a very important role in fire-fighting and rescue of water supply. However, some unit leaders do not pay enough attention to this, do not have professional and technical personnel, do not entrust qualified fire protection and maintenance companies to manage, and do not use advanced management techniques, resulting in fire water supply equipment with "disease" operation, resulting in abnormal conditions, mainly The problem has the following points:
1.1 The water level of the fire water tank (pool) cannot be guaranteed enough. In accordance with the regulations, the roof of the building should generally have a fire tank not less than 18m3 high, and ensure its full water level. In the initial stage of the fire, it can ensure the fire water consumption for ten minutes; on the ground or in the basement, According to the amount of water used in a building, a fire-fighting pool of not less than 300m3 is generally provided to ensure the fire-fighting and indoor fire hydrant one hour of fire-extinguishing capacity. When the water level of the tank (pool) is insufficient, the system should be able to automatically start filling water. However, some units lack management, and the floating ball valve of the water tank (pool) is not repaired or replaced in time. To prevent water spillage and power saving, the supplemental water pump and inlet valve are often closed, resulting in some units of water tank (pool) water not Adequate, water will be cut shortly after the fire is sprayed.
1.2 The fire pump cannot guarantee normal startup. When a fire occurs, the closed sprinkler reaches a certain ambient temperature and bursts, spraying water. The flow of water in the pipe network creates a pressure difference. The valve in the alarm valve will open automatically and the pressure water will flow to the main pipe. Time delay device, impulse alarm signal is issued to the impulse water and the pressure switch is activated. The contact signal activates the spray pump. The fire hydrant is started automatically in the fire hydrant box or in the fire control room. However, some units do not have adequate fire control and do not provide two-way fire protection power in accordance with the regulations. They cannot switch automatically at the end. Some spray pump and fire hydrant pump electrical control cabinet switches are placed in manual or stop positions. They cannot start automatically when a fire occurs. The best time to extinguish the fire.
1.3 The water supply pipe network cannot guarantee that the highest level of the pressurized water structure is closer to the high fire water tank on the roof. It is obviously not enough to rely on the natural pressure of the water in the water tank. A stabilizing pump must be used to regulate the most unfavorable floors to ensure the most unfavorable points. There is still pressure water supply to extinguish fire when a fire occurs on the floor. But some units ignore the management of the regulator pump, some electrical control cabinets are not set in the automatic state, some will not properly adjust the use of pressure, some set in the tank side of the regulator pump, the sun and rain, equipment rust , lack of maintenance, a considerable part of the regulator pump can not work properly, the most unfavorable floor of the water supply pipe network water pressure is insufficient.
1.4 Management of water supply facilities does not guarantee that safe and effective fire-fighting water supply facilities are mainly distributed in the fire pump rooms and high-level fire water tanks in the basement. Regular maintenance and periodic testing are required. However, some fire management personnel have low professional qualifications and are not suitable for modern fire management requirements. Depending on inspection by inspection personnel, the frequency is difficult to guarantee, and problems are found. In inspections, some personnel only “click†to see if the pump is finished, the pressure has not risen, the valve is not fully open, and the pipe network dynamic pressure is not Qualified did not test, some just go to see a sign, more to see or not, one day to sign the month's records, the superior is difficult to understand the true situation of the system. At this stage of fire management methods, fire agencies (intermediaries) are also difficult to real-time supervision of the unit's water supply facilities, but there is no good means to fully grasp the operational status of fire protection facilities in all units.
2 Application of Internet of Things Technology in Maintenance and Management of Fire Water Supply Facilities
According to the requirements of modern fire management, the status information and related data of fire-fighting facilities should be collected and integrated. The application of Internet of Things technology to the maintenance and management of fire-fighting water facilities can effectively solve the problem that the “static†of fire-fighting facilities is not perfect and “dynamic†is not reliable. Outstanding issues.
2.1 Concepts, Principles, and Functions of the Internet of Things The Internet of Things uses a variety of sensors and electronic tags to format the information of electronic information, and then implements multi-interface exchange of information through information transmission methods such as WIFI, ZIGBEE, infrared, and Bluetooth. Communication, and then through the Internet and its corresponding "cloud" server to achieve information concentration and processing to meet people's identification, positioning, intelligent analysis of a network structure.
The application of Internet of Things technology in firefighting water supply facilities solved the complete collection and integration of key “static†key parameters for firefighting water supply facilities. At the same time, due to real-time continuous monitoring of the Internet of Things technology, a powerful data center was established in the background to provide water for firefighting. The “dynamic†real-time analysis of the facility formation system solved a series of problems such as “discrete†nature of human inspection, visual fatigue, and unbalanced technical level. At the same time, it also allowed fire-fighting water supply facilities to be upgraded from personnel management to computer intelligence management, improving The management level and efficiency provide an open interface for fire water supply facilities for the development of smart cities.
2.2 Application of IoT in firefighting and water supply facilities The Internet of Things is to format information into electronic information. If this technology is introduced in the field of firefighting, this is a brand-new research topic. The principle of IoT technology will be used to target firefighting water supply facilities. The problem can be designed for fire water supply automatic monitoring and management system.
2.2.1 Working principle As shown in Figure 1, the system consists of a pressure transmitter, a liquid level transmitter, a remote terminal unit (RTU), a data transmission unit (DTU), and a power supply system. Pressure monitoring of key points of the water supply system, installing a three-way pressure at the bottom of the pressure gauge where needed, and installing the pressure transmitter vertically on the pipe network. The vertical is to prevent dew condensation water from entering the internal circuit of the transmitter. The circuit is adversely affected. A ball valve is prepared before the pressure transmitter to facilitate testing and maintenance. The transmitter converts the 0-16MP water pressure signal into a 0-24MA current signal, so that the remote terminal unit (RTU) obtains the water pressure signal while supplying power to the pressure transmitter, and then through the data transmission unit ( DTU) is sent to the cloud server on the Internet, and the cloud server enhances various applications to share with various intelligent terminals through the Internet. The cloud server can store large amounts of data as well as analyze the entire data. In smart terminals, we can also personalize the logical relationship of data operations to achieve distributed computing and data sharing.
Application of Internet of Things Technology in Maintenance and Management of Fire Water Supply Facilities
2.2.2 Function Introduction (1) Remote Terminal Unit (RTU) can access 14 groups of analog quantities, such as: water pressure, water level, voltage, current, temperature, humidity and so on.
(2) The remote terminal device (RTU) can access 24 sets of switches, such as: dual power supply for fire control cabinets, manual and automatic, start and stop, and opening and closing of signal valves.
(3) The data transmission unit (DTU) can set the heartbeat frequency within 5 to 65535 seconds and adjust the interval data flow control cost. A fire-fighting information report for a 40-building month is only 25M uploads.
(4) The internal custom protocol makes the message more efficient, which reduces the space occupied by the cloud storage and reduces the bandwidth occupied by the transmission.
2.2.3 Application Diagram The core position of the fire water supply facility is the fire pump room, where there are pools, pumps, fire pump control cabinets, and alarm valves. A remote terminal device (RTU) is installed in the pump room to collect data in a star shape. Collecting firefighting information in the pump room, the star type is also called multi-line type in firefighting, so that the collection path is more reliable, because there is no difficulty in the relatively concentrated signal wiring in the same space and the information reliability requirements are high. In this way, we use the RS485 bus or power carrier system for the collection of information in the high water tanks and the most unfavorable pressure distributions, as shown in Figure 2.
Application of Internet of Things Technology in Maintenance and Management of Fire Water Supply Facilities
The software platform also integrates powerful management functions. In addition to online access to the operating parameters of the fire-fighting water supply facilities, the management behavior of the two-dimensional code binding staff can also be used to achieve simultaneous upgrades of technology upgrades and simultaneous upgrades. The form's behavior was changed to the computer system to assist in the completion of the system automatically generate inspection schedule, the problem of patrolling can map culture in real-time upload more intuitive and image, handwriting inspection identity confirmation, so that management can be more seamlessly drilled, such as : When a leak was discovered somewhere at a certain time, the system automatically reported the discovery time. When the inspection personnel used the handset to report the inspection information, they could take pictures on the spot and upload it along with them. The final inspection person's signature was confirmed by hand.
3 Things <br> <br> technical superiority was on the management network in the fire water supply facilities maintenance is a new technology, fire protection applications is to achieve fire management innovation and transformation and upgrading, change the existing management model to improve the fire safety facilities Maintaining the management level will be of great help.
3.1 Achieving Intelligent Management of Water Supply Facilities Fire-fighting water supply facilities are an important part of fire-fighting facilities. The normality of fire-fighting water supply facilities is directly related to the possibility of self-extinguishing in the early stages of fires, and is also the guarantee for the maximum acquisition of fire-fighting and rescue time. The management method is still in the stage of manual management and cannot meet people's demands for real-time control of fire-fighting water supply facilities. By installing sensors in key parts of firefighting water supply facilities, such as: water tank (pool) liquid level transmitter, installing pressure transmitter at the most unfavorable point, the fire double power supply and fire control cabinet (self) can be assisted by the relay. Contact acquisition, through the RS485, CAN bus summary to the remote terminal device RTU, and then the data transmission unit DTU real-time information sent to the remote cloud server, the maintenance unit and the fire department can be authorized to query the status of the fire water supply system in real time, Realize the intelligent management of fire water supply system.
3.2 Enhanced Fire Information Control Ability At present, the Fire Commander* received the fire instruction and the commander could not hold the most real intelligence in the fire field for the first time. For example: the fire water tank (pool) water level, and the fire pump control cabinet in the fire water supply facility is Whether the water pressure in the fire control network meets the requirements in the manual state or the automatic state, the firefighting* often arrives at the fire site to develop the firefighting and rescue implementation plan through on-site rapid reconnaissance, delaying the best time for firefighting, and applying the Internet of Things technology is quite different. Firefighting * At the moment when the fire alarm is received, the fire commander's handheld intelligent terminal can establish real-time air connection with the on-site IoT firefighting system, whether it is "static" water level, pressure, manual and automatic, dual power supply, or The “dynamic†water level, water pressure, etc., change process, without exception, a comprehensive and intuitive display in front of the fire commander, assistant commander to make the correct decision, and more importantly, this decision is on the way to the fire. Completed, there is no one-second-a-second on-site rescue to ensure that * can beat and win. At the same time, the Internet of things technology can also provide commanders with information on the amount of water and water pressure in the water supply system in the fire field. The fire commander can understand the working status of the fire protection facilities in the fire field in real time through the mobile terminal, and can remotely control the site personnel for different situations. Emergency treatment, such as: fire commander found that the fire pump is not in automatic state, you can pop up the contact information of the on-duty personnel through the handheld terminal, notify them the normal status of the fire pump at the first time, and according to this intelligence request targeted dynamic reinforcement. Program.
3.3 Completed routine inspections of inspection and maintenance personnel of maintenance and archives data. The information was collected through the form-filling method, and the intelligent management of fire-fighting water supply facilities was changed. The information that had been unilaterally managed by people was collected and replaced by computer-based. The platform is automatically collected and the QR code on the target device is scanned. The information is immediately uploaded to the data center through the WIFI or GPRS network, and an inspection file is automatically generated. The method has both authenticity and statistical summary. It also realizes a paperless office and greatly improves the continuity and objectivity of collection. At the same time, the introduction of computer file management makes it convenient to read, share, and analyze personnel data.
3.4 Increased maintenance efficiency The intelligent management of fire-fighting water supply systems has caused abnormal conditions in fire-fighting water supply equipment. For example, as long as a small leakage point of pipe network is found, it can be analyzed through real-time continuous pressure curves. This is a traditional manual inspection. It is difficult to judge whether the pressure is on the decline of man-made pressure or the problem of the pipeline network. Intelligent management of fire-fighting water supply facilities can promptly detect problems. Within 40 seconds after the switch action, the mobile platform of the project owner will receive the information on the amount of change, and the equipment inspection will also realize a paperless real-time online inspection. Routine maintenance of firefighting equipment The system will automatically record every detail of maintenance for post-mortem inspection.
4 Conclusion
At present, the country is planning the innovation and application of the Internet of Things industry in all walks of life, accelerating enterprise innovation and industrial transformation. The application and development of the Internet of Things in the fire protection industry has a lot to do, not only in the fire water supply facilities, but also in other fire protection systems. development of. Fire-fighting workers and related scientific and technical personnel should seize the opportunity to overcome difficulties, actively apply new technologies to solve problems arising from human management, apply fire-fighting water supply facilities to the Internet of Things technology, achieve intelligent management, and change existing fire management The model, improving the level of fire management, and increasing the safety and reliability of fire protection facilities will certainly play an important role.
1 main problems in fire water supply facilities
Fire-fighting water supply facilities are the key equipment for the unit's fire-fighting facilities, and play a very important role in fire-fighting and rescue of water supply. However, some unit leaders do not pay enough attention to this, do not have professional and technical personnel, do not entrust qualified fire protection and maintenance companies to manage, and do not use advanced management techniques, resulting in fire water supply equipment with "disease" operation, resulting in abnormal conditions, mainly The problem has the following points:
1.1 The water level of the fire water tank (pool) cannot be guaranteed enough. In accordance with the regulations, the roof of the building should generally have a fire tank not less than 18m3 high, and ensure its full water level. In the initial stage of the fire, it can ensure the fire water consumption for ten minutes; on the ground or in the basement, According to the amount of water used in a building, a fire-fighting pool of not less than 300m3 is generally provided to ensure the fire-fighting and indoor fire hydrant one hour of fire-extinguishing capacity. When the water level of the tank (pool) is insufficient, the system should be able to automatically start filling water. However, some units lack management, and the floating ball valve of the water tank (pool) is not repaired or replaced in time. To prevent water spillage and power saving, the supplemental water pump and inlet valve are often closed, resulting in some units of water tank (pool) water not Adequate, water will be cut shortly after the fire is sprayed.
1.2 The fire pump cannot guarantee normal startup. When a fire occurs, the closed sprinkler reaches a certain ambient temperature and bursts, spraying water. The flow of water in the pipe network creates a pressure difference. The valve in the alarm valve will open automatically and the pressure water will flow to the main pipe. Time delay device, impulse alarm signal is issued to the impulse water and the pressure switch is activated. The contact signal activates the spray pump. The fire hydrant is started automatically in the fire hydrant box or in the fire control room. However, some units do not have adequate fire control and do not provide two-way fire protection power in accordance with the regulations. They cannot switch automatically at the end. Some spray pump and fire hydrant pump electrical control cabinet switches are placed in manual or stop positions. They cannot start automatically when a fire occurs. The best time to extinguish the fire.
1.3 The water supply pipe network cannot guarantee that the highest level of the pressurized water structure is closer to the high fire water tank on the roof. It is obviously not enough to rely on the natural pressure of the water in the water tank. A stabilizing pump must be used to regulate the most unfavorable floors to ensure the most unfavorable points. There is still pressure water supply to extinguish fire when a fire occurs on the floor. But some units ignore the management of the regulator pump, some electrical control cabinets are not set in the automatic state, some will not properly adjust the use of pressure, some set in the tank side of the regulator pump, the sun and rain, equipment rust , lack of maintenance, a considerable part of the regulator pump can not work properly, the most unfavorable floor of the water supply pipe network water pressure is insufficient.
1.4 Management of water supply facilities does not guarantee that safe and effective fire-fighting water supply facilities are mainly distributed in the fire pump rooms and high-level fire water tanks in the basement. Regular maintenance and periodic testing are required. However, some fire management personnel have low professional qualifications and are not suitable for modern fire management requirements. Depending on inspection by inspection personnel, the frequency is difficult to guarantee, and problems are found. In inspections, some personnel only “click†to see if the pump is finished, the pressure has not risen, the valve is not fully open, and the pipe network dynamic pressure is not Qualified did not test, some just go to see a sign, more to see or not, one day to sign the month's records, the superior is difficult to understand the true situation of the system. At this stage of fire management methods, fire agencies (intermediaries) are also difficult to real-time supervision of the unit's water supply facilities, but there is no good means to fully grasp the operational status of fire protection facilities in all units.
2 Application of Internet of Things Technology in Maintenance and Management of Fire Water Supply Facilities
According to the requirements of modern fire management, the status information and related data of fire-fighting facilities should be collected and integrated. The application of Internet of Things technology to the maintenance and management of fire-fighting water facilities can effectively solve the problem that the “static†of fire-fighting facilities is not perfect and “dynamic†is not reliable.

3 Things <br> <br> technical superiority was on the management network in the fire water supply facilities maintenance is a new technology, fire protection applications is to achieve fire management innovation and transformation and upgrading, change the existing management model to improve the fire safety facilities Maintaining the management level will be of great help.
3.1 Achieving Intelligent Management of Water Supply Facilities Fire-fighting water supply facilities are an important part of fire-fighting facilities. The normality of fire-fighting water supply facilities is directly related to the possibility of self-extinguishing in the early stages of fires, and is also the guarantee for the maximum acquisition of fire-fighting and rescue time. The management method is still in the stage of manual management and cannot meet people's demands for real-time control of fire-fighting water supply facilities. By installing sensors in key parts of firefighting water supply facilities, such as: water tank (pool) liquid level transmitter, installing pressure transmitter at the most unfavorable point, the fire double power supply and fire control cabinet (self) can be assisted by the relay. Contact acquisition, through the RS485, CAN bus summary to the remote terminal device RTU, and then the data transmission unit DTU real-time information sent to the remote cloud server, the maintenance unit and the fire department can be authorized to query the status of the fire water supply system in real time, Realize the intelligent management of fire water supply system.
3.2 Enhanced Fire Information Control Ability At present, the Fire Commander* received the fire instruction and the commander could not hold the most real intelligence in the fire field for the first time. For example: the fire water tank (pool) water level, and the fire pump control cabinet in the fire water supply facility is Whether the water pressure in the fire control network meets the requirements in the manual state or the automatic state, the firefighting* often arrives at the fire site to develop the firefighting and rescue implementation plan through on-site rapid reconnaissance, delaying the best time for firefighting, and applying the Internet of Things technology is quite different. Firefighting * At the moment when the fire alarm is received, the fire commander's handheld intelligent terminal can establish real-time air connection with the on-site IoT firefighting system, whether it is "static" water level, pressure, manual and automatic, dual power supply, or The “dynamic†water level, water pressure, etc., change process, without exception, a comprehensive and intuitive display in front of the fire commander, assistant commander to make the correct decision, and more importantly, this decision is on the way to the fire. Completed, there is no one-second-a-second on-site rescue to ensure that * can beat and win. At the same time, the Internet of things technology can also provide commanders with information on the amount of water and water pressure in the water supply system in the fire field. The fire commander can understand the working status of the fire protection facilities in the fire field in real time through the mobile terminal, and can remotely control the site personnel for different situations. Emergency treatment, such as: fire commander found that the fire pump is not in automatic state, you can pop up the contact information of the on-duty personnel through the handheld terminal, notify them the normal status of the fire pump at the first time, and according to this intelligence request targeted dynamic reinforcement. Program.
3.3 Completed routine inspections of inspection and maintenance personnel of maintenance and archives data. The information was collected through the form-filling method, and the intelligent management of fire-fighting water supply facilities was changed. The information that had been unilaterally managed by people was collected and replaced by computer-based. The platform is automatically collected and the QR code on the target device is scanned. The information is immediately uploaded to the data center through the WIFI or GPRS network, and an inspection file is automatically generated. The method has both authenticity and statistical summary. It also realizes a paperless office and greatly improves the continuity and objectivity of collection. At the same time, the introduction of computer file management makes it convenient to read, share, and analyze personnel data.
3.4 Increased maintenance efficiency The intelligent management of fire-fighting water supply systems has caused abnormal conditions in fire-fighting water supply equipment. For example, as long as a small leakage point of pipe network is found, it can be analyzed through real-time continuous pressure curves. This is a traditional manual inspection. It is difficult to judge whether the pressure is on the decline of man-made pressure or the problem of the pipeline network. Intelligent management of fire-fighting water supply facilities can promptly detect problems. Within 40 seconds after the switch action, the mobile platform of the project owner will receive the information on the amount of change, and the equipment inspection will also realize a paperless real-time online inspection. Routine maintenance of firefighting equipment The system will automatically record every detail of maintenance for post-mortem inspection.
