AI Technical Summary

Problems solved by technology

[0002] At present, the damper control in various fire-fighting smoke exhaust and air-conditioning control systems on the market mainly adopts a simple wired control mode to realize the start-stop control of the damper and the detection function of the damper state. Therefore, the damper control The system wiring is complicated, the construction volume of the control system is large, and the system installation and maintenance costs are high

With the continuous expansion of the scale of my country's fire protection industry, the improvement of fire protection industry technology and the development of intelligent fire protection, the air valve control control mode using wired monitoring is increasingly unable to meet the needs of modern fire protection due to its shortcomings such as poor anti-interference and difficult installation and maintenance. System Monitoring Requirements

At the same time, in order to master the working status data of the air valves in the building, the building fire control and air conditioning control room needs to monitor the operating status of the dampers at each site and communicate with the fire control host. Since the dampers are in a distributed state, the existing wired monitoring network Can no longer meet the requirements of the new monitoring mode

[0003] At present, the wired air valve monitoring system adopts the bus coding mode. This system uses a bus network. When a node in the network fails, it will affect the operation of the entire network, and its reliability, real-time performance and anti-interference performance are poor. At the same time, the scalability of the network is poor, which is not convenient for the expansion of the damper monitoring network scale

Some systems also use other network structures (such as CAN monitoring network) to improve the performance of the monitoring system to a certain extent, but still use wired network systems, and the anti-interference and reliability of the system are still not high, which limits its application in fire protection and air conditioning.
