Problems solved by technology

However, the monitoring system depends on the reliable communication network to monitor the internal equipment of the substation. Once the communication network is abnormal, the communication between the monitoring system and all the internal equipment of the substation will be interrupted unexpectedly, which will cause the internal equipment of the substation to run without monitoring. There are many security risks
[0003] In the prior art, there are many reasons for the interruption of communication. When the communication between the monitoring system and the content equipment of the substation is interrupted, the operating personnel need to check the reasons for the interruption of communication one by one, and deal with the cause of the interruption of the communication, which will Causes slow speed in locating the cause of communication outages

Abstract

The invention discloses a fault detection method and device. The fault detection device establishes the network connection with electronic equipment through the network connection equipment; the method comprises the following steps: acquiring the current connection state of the current electronic equipment through the communication process; judging whether the connection state of the monitor process corresponding to the current electronic equipment is changed according to the current connection state and the preset connection state, wherein the preset connection state is the initial connection state for representing the current electronic equipment; when judging that the connection state of the monitor process is changed, judging whether the network between the fault detection device and the electronic equipment is connected; if judging that the network between the fault detection device and the electronic equipment is not connected, determining that the network connection equipment is in fault.

Description

Technical field [0001] The present invention relates to automatic communication technology in the field of power electronics, in particular to a fault detection method and device. Background technique [0002] With the rapid development of the power industry, advanced power system substation automation systems have become an inevitable trend in the development of this field. Operators can accurately monitor the operation of the internal equipment of the substation through the substation automation system, and can also remotely control some equipment, which greatly improves the intelligent management of the internal equipment of the substation. However, the monitoring system monitoring the internal equipment of the substation is dependent on a reliable communication network. Once the communication network is abnormal, the communication between the monitoring system and all the internal equipment of the substation will be interrupted unexpectedly, which will cause the internal equi...
