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...

AI Technical Summary

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 failure in a strong nuclear electromagnetic pulse environment. The control device is composed of multiple cables, which can generate large electromagnetic interference energy in an electromagnetic pulse environment. And it is easy to introduce into the system and cause damage to the key sensitive components of the system

Civil air defense projects are located underground, and some are built in mountains. The underground environment is humid, and the internal humidity is high all the year round. Sometimes it is threatened by groundwater. Mold is easy to breed in the project, which will greatly corrode the control device and electrical components.
