Method for diagnosing communication state of distribution automation terminal

Abstract

The present invention relates to the field of communication diagnosis, and more particularly, to a method for diagnosing the communication state of a distribution automation terminal. The method comprises the following steps of: S1, detecting the time delay of a communication signal of the distribution automation terminal; S2, detecting the packet loss rate in the distribution automation terminalcommunication process; and S3, analyzing the time delay and the packet loss rate to obtain the communication state of the distribution automation terminal. The invention provides a method for diagnosing the communication state of the distribution automation terminal, which uses the time delay characteristic and the packet loss rate of the communication signal of the distribution automation terminal device to describe the communication state of the terminal device, and makes up for the vacancy in this respect in the past; and before the detection of the distribution automation equipment, the communication state is diagnosed, when the time delay and the packet loss rate are too large, the accuracy of the detection result is low and the reliability is not high, on the contrary, when the timedelay and the packet loss rate are small, the reliability of the test results is high, and as a result, the method can obtain a correct reference about the accuracy of the detection result.

Description

technical field [0001] The invention relates to the field of communication diagnosis, and more specifically, to a method for diagnosing the communication state of a power distribution automation terminal. Background technique [0002] In the past, the distribution automation equipment was connected to the detection equipment through wired or wireless when doing the test, but in the past detection process, it often encountered problems caused by the strength of the communication signal. Detection in areas with strong communication signals is often smooth, and the detected data is no problem. However, if the signal strength is weak (such as in remote areas), the data detected by the distribution automation terminal equipment at this time will often appear abnormal, and these abnormal phenomena are generally caused by missing data. of. The strength of the communication signal will have an important impact on the detection results of the distribution automation terminal equipm...
