Problems solved by technology

At present, most of the electric protective door control devices in civil air defense projects adopt the form of traditional relay combined logic control loop, which has the disadvantages of complex construction, too many fault points, inconvenient maintenance, etc., and cannot realize the networking function; if you want to change the control function, you need to modify the hardware Circuit control loop, quite cumbersome, and low reliability, weak anti-interference ability, poor applicability
The control devices of electric protective doors in civil air defense projects are all installed near the entrance of the project, which is prone to fa

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] The present invention is an electric protective door control device for civil air defense engineering, comprising an explosion-proof operation cabinet, a touch screen 1, a PLC 2, an explosion-proof pager 3, an intermediate relay 4, an AC contactor 5, a terminal block 6, an electric protective door 7, and a hot blower 8 , Electric ball valve 9, limit switch 10, temperature and humidity sensor 11.

[0020] Among them, the explosion-proof operation cabinet (not shown in the figure) is designed with industrial explosion-proof grade, made of stainless steel, and the cabinet body is sealed, which not only effectively shields electromagnetic interference, but also improves the anti-corrosion performance of the explosion-proof operation cabinet. A temperature and humidity sensor 11 is installed in the explosion-proof operation cabinet, and a hot
