The installation of automatic fire control system can effectively prevent and reduce fire hazards, protect personal and property safety, and improve the ability of wind turbine fire prevention. The fire fighting system is composed of an interconnected fire alarm controller, fire detector, manual fire alarm button, fire sound and light alarm, manual start and stop button, fire extinguishing device and monitoring system. The fire detector is composed of smoke detector, temperature detector, flame detector, temperature electrical disaster detector and carbon monoxide fire detector. The fire fighting system is installed in the engine room, tower and wheel hub of the wind turbine, which can detect the early characteristics of the fire, send out the fire alarm signal and automatically start the fire extinguishing equipment, and has the role of preventing the spread of fire. The system can realize remote monitoring, remote control, remote alarm, remote data call and other functions through the monitoring software.

The inside of wind turbine is a completely enclosed space, and its internal environment is more severe than that of open space in any aspect, so it has higher requirements for shock resistance, electromagnetic interference and temperature. In order to meet the requirements, our company adopts anti-interference, stable and reliable optical fiber network as the information transmission medium, uses industrial Ethernet technology to transmit monitoring data, and uses ring network technology to ensure the stability and reliability of automatic fire system data.

In the automatic fire protection system, NEU50244T8CGS-SFP core switch and NEU3042GM-SFP management switch are used to form a gigabit optical fiber link redundant self-healing ring network. Data is transmitted to the control center by connecting the management switch inside each fan with the fire alarm controller and video surveillance camera that can realize the effect of remote monitoring of the lower fan in the control center, and then achieve the function of video monitoring and linkage alarm.
