Abstract

The invention discloses a monitoring method and device for a communication power supply. The monitoring method for the communication power supply comprises the steps of obtaining transmission signals in a network; judging whether the transmission signals are synchronous lost alarm signals or not, wherein the synchronous lost warning signals are used for giving an alarm when the communication power supply is powered off; if it is judged that the transmission signals are the synchronous lost warning signals, determining that the communication power supply is powered off. According to the monitoring method and device for the communication power supply, the problem that only the working status of a communication power supply of a transformer substation with the concentrated arrangement and the output voltage being equal to or larger than 110 kV can be monitored in the prior art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a monitoring method and device for communication power supply. Background technique [0002] The power communication system can be used to transmit power grid relay protection signals, power grid load monitoring signals, etc. These signals may be voice signals, image signals, and the like. And these signals can be transmitted in the form of digital signals. Although the information volume of the signal transmitted by the power communication system is not large, the quality of the communication signal is very high in the operation of the power grid, which puts forward high requirements on the reliability and stability of the power communication system. The reliability and stability of the power communication system depends on the stability of the communication power supply system. Therefore, it is very important to effectively monitor the working status of the communication po...
