Description

technical field

[0001] The invention relates to the field of electric control of communication base stations, in particular to a power failure detection method and a power failure sensor. Background technique

[0002] At present, the power outage monitoring of communication base stations mainly collects power outage information through switching power supplies, and uploads them to the operation and maintenance system through the communication interface through the dynamic ring FSU. However, due to the stock switching power supply, a considerable part of the communication interface and monitoring modules are faulty, and the power failure information cannot be obtained in time, and the power generation cannot be distinguished from the normal mains power supply. There is no effective means to control the timeliness of power generation of communication services and trustworthiness of power generation.
