Remote control system for local ventilations The remote control system of the underground ventilator mainly includes the intelligent local ventilation of the underground, the remote control converter, and the ground centralized control platform, and realize the display, remote opening and closing of the operating parameters of the local ventilation. The underground intelligent local ventilation is mainly based on the characteristics of the coal mine's own disaster, and the variable frequency conversion control of the excavated working surface is controlled to reduce the energy consumption of the ventilation of the mine. Starting from the requirements of safety and energy saving, the system is regulated in real time to the fans' speed, achieving the effect of "real -time warning, human -machine dual control, demand for wind and disaster prevention and mitigation", so that local ventilation of mines, automatic gas emissions are efficient and safe. Reduce gas accidents, and can also con…
