Communication base station safety monitoring device

Abstract

The invention discloses a communication base station safety monitoring device, which comprises a power supply module, an electric energy acquisition module, a controller and a wireless module. The power supply module is used for providing a stable +5V power supply; the electric energy acquisition module adopts a voltage sensor to detect a voltage signal on a power supply line of a power supply ofthe communication base station in real time; a signal amplification conditioning circuit effectively filters interference of magnetic devices in the communication base station and external electromagnetic clutter signals by applying a band-pass filter principle, and effectively eliminates bias voltage, so that the accuracy of a detection signal amplification value is ensured; an anti-interferencestabilizing circuit effectively eliminates interference when harmonic waves or voltage surges exist in the power supply line of the communication base station power supply, so that the anti-interference performance of the monitoring device is improved; and the controller sends the electric energy detection data to a background monitoring server through the wireless module for monitoring and management, so that accurate remote monitoring of the power supply performance of the communication base station is achieved. Good reliability and maintainability are achieved.

Description

technical field [0001] The invention relates to the technical field of communication base station monitoring, in particular to a communication base station safety monitoring device. Background technique [0002] With the rapid development of mobile communication, the number of communication base stations is constantly increasing, and the technical content and complexity of equipment are also getting higher and higher. Correspondingly, higher requirements are put forward for the stability and reliability of communication base station power supplies. The communication power supply is an important part of the communication network infrastructure. It provides DC (-48V or -24V) power supply for the communication equipment of the base station. In order to improve the reliability of the power supply system, most power modules are configured in N+1 mode. The reliability of the power supply equipment under the conditions can meet the communication requirements. However, in the case ...
