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
