Switching of ventilation fan damper

The non-stop wind turbine system mainly consists of two components, namely the online monitoring and fault analysis system and the non-stop wind turbine damper system. Among them, the online monitoring and fault analysis system consists of industrial control computer, upper computer configuration software, PLC measurement and control system, intelligent data acquisition unit, video monitoring and other parts. This system uses Siemens S7 series PLC as the control center, which can achieve centralized control of the electrical part of the fan. Through sequential control programs, the control function of the fan can be conveniently achieved. Detect the control functions and operating parameters of the ventilation fan, corresponding motor frequency conversion device, electric damper, etc. in the main ventilation room, and transmit the data to the ground production dispatch center for real-time monitoring, control, alarm and display, achieving functions such as one key start, one k…
