With the rapid development of urban scale, high-rise buildings are increasing.On the one hand, high-rise buildings have complex functions, dense personnel, and many modern facilities. Once a fire occurs, it is easy to produce chimney effect and wind effect, the fire spreads rapidly, and it is very difficult to extinguish.On the other hand, in the use of high-rise buildings, property management units have relatively weak awareness of fire protection, and it is often easy to ignore the management and maintenance of fire protection systems such as fire water supply systems and automatic sprinkler systems.
At present, the water pressure of the fire protection system pipeline cannot be monitored in real time, and it is difficult for the fire department to effectively monitor the fire water pressure, resulting in some fire protection systems being in a state of insufficient or even no water pressure for a long time.Once a fire occurs, the fire protection system cannot be connected in time, and the hidden dangers of fire protection are very serious, which will undoubtedly bring great harm to the lives and properties of the people.In actual circumstances, once the water pressure of the fire pipeline is abnormal, after manual discovery, the inspectors notify the firefighters to rush to the site for repairs. The whole process is relatively long, and the abnormal water pressure of some fire pipelines cannot be found in time, and it is difficult for the inspectors to understand the cause of the abnormality. Delayed exception processing time.
To solve this problem, the pressure sensor can be installed in the key parts of the fire water system to realize the water pressure monitoring of the fire pipeline in the building. This system is called the fire pipeline water pressure monitoring system.
The fire pipeline pressure monitoring system transmits the monitoring data of the pressure sensor to the fire pipeline water pressure monitoring platform through the GPRS data collector, realizes the abnormal pressure data alarm, and conducts online monitoring and comprehensive analysis of the operation of the entire fire water system, which can quickly locate the fire fighting. The fault points existing in the pipeline, and push the alarm information to the relevant management personnel through SMS, WeChat, email, etc., to deal with the failure of the fire pipeline or the alarm problem in time, reduce the hidden danger of fire protection, and ensure that the fire water system can work properly in the event of a fire. make a real difference.
Fire pipeline water pressure monitoring system is divided into three parts: perception layer, transmission layer and application layer.The perception layer is located in the first layer of the three-layer structure of the Internet of Things, and its function is “perception”, that is, to obtain environmental information through the sensor network, which is the core of the Internet of Things.The sensing layer of the fire pipeline water pressure monitoring system is mainly the pressure transmitter, which is the key part of the fire pipeline water pressure information collection.
Anxing pressure transmitter adopts high-performance pressure-sensing chip, combined with advanced circuit processing and temperature compensation technology, to convert pressure changes into linear current or voltage signals.The product is small in size, easy to install, and uses a stainless steel shell to isolate and prevent corrosion. It is suitable for measuring gases and liquids that are compatible with the materials in contact with it. It can be used to measure gauge pressure, negative pressure and absolute pressure.It is suitable for the measurement of process control pressure in the industrial field. It is widely used in water plants, oil refineries, sewage treatment plants, building materials, light industry, machinery and other industrial fields to realize the measurement of liquid, gas and steam pressure.
GPRS data collector is a terminal device suitable for field equipment monitoring and control and wireless transmission through GPRS. Function (optional), the product is waterproof.
The network layer is the core of data communication and the main channel of data transmission. The network layer of the fire pipeline water pressure monitoring system mainly adopts the GPRS communication network, which has the advantages of wide coverage, multiple connections, fast speed, low cost, low power consumption, excellent architecture, Real-time performance and so on.
The application layer is the fire pipeline water pressure monitoring platform and the third-party application platform, which realizes the real-time monitoring of the monitoring point location, equipment type and real-time data of the fire pipeline water pressure monitoring system. The user can push real-time monitoring information and alarm information to facilitate timely maintenance by staff and improve the reliability of the entire fire protection system.
The limitations of traditional fire protection are relatively large, and intelligent fire protection based on Internet of Things technology has become an inevitable trend. With the development of Internet of Things technology and fire protection facilities, smart fire protection is now an indispensable part of smart city construction and a specific application in the field of smart city fire protection.
