Self-checking device and method for strong current invasion prevention alarm equipment of distributing frame and monitoring system

Abstract

The embodiment of the invention discloses a self-checking device and a self-checking method for strong current invasion prevention alarm equipment. The alarm equipment comprises a detection ring sensor and an intelligent signal acquisition device which are mutually connected. The self-checking device comprises a test load, a test power supply for supplying alternating-current (AC) power required by the self check and a test line, wherein the test line passes through the detection ring sensor and is connected with the test load and the test power supply so as to form a test loop; and when the test power supply is connected with the test loop, strong current invasion current is generated, so that the self-checking device can detect whether the operating state of the alarm equipment is normal or not according to whether the alarm equipment can alarm or not by aiming at the strong current invasion current. According to the embodiment of the invention, the operating state of a strong current invasion prevention monitoring system for a distributing frame can be effectively detected, so that the strong current invasion to the distributing frame can be found in time, and the normal operation of the distributing frame is ensured.

Description

technical field [0001] The invention belongs to the technical defense field of communication security, and in particular relates to a self-inspection device, method and monitoring system for an anti-strong current intrusion alarm device of a distribution frame. Background technique [0002] In the communication system, the distribution frame in the communication room plays an important role as a bridge connecting the communication equipment inside and outside the room. When the communication lines on the communication equipment outside the computer room are in contact with strong electricity, it will cause strong electricity intrusion, resulting in damage to the communication equipment in the computer room, and even cause a fire in severe cases. In order to ensure the safe operation of the distribution frame, in the prior art, a set of monitoring system, called: the distribution frame anti-strong current intrusion monitoring system, is used to monitor whether the working sta...

Problems solved by technology

Therefore, it is impossible to confirm whether the distribution frame anti-strong current intrusion monitoring system can normally alarm when strong current intrusion actually occurs. When the self-test is normal, it may still occur when strong current intrusion occurs. If the alarm cannot be detected, if the fault of the distribution frame anti-strong current intrusion monitoring system cannot be detected in time, when the distribution frame has a strong current intrusion, it cannot be detected in time through the distribution frame anti-strong current intrusion monitoring system, thereby lead to very serious consequences
