Abstract

The invention discloses an electromagnetic lock type metal net protection system which comprises a wall body, and two guardrails arranged in parallel are fixedly installed on the wall body. A sliding door is arranged between the two guardrails; an electromagnetic lock, a proximity switch and a warning lamp are arranged on the sliding door; the electromagnetic lock is connected with the warning lamp in parallel, and the warning lamp is connected with the table body control switch in series through the proximity switch to form a direct-current 12V control loop; the warning lamp is also connected in parallel with an alternating current contactor; the electromagnetic lock is used for locking the sliding door when a power supply is switched on, the proximity switch is used for detecting the closing state of the sliding door, and the warning lamp is used for sending out a warning signal when a person approaches. According to the invention, a worker can be prevented from mistakenly entering a test area, and the safety and convenience of use are improved.
