At present, in the operation of power dispatch automation systems, many substations adopt a direct network networking method, in which no optical modem system is installed. Instead, optical cables are installed in the communication room and the fiber optic network is connected to the integrated server. When detecting network channels, the specific detection method and process are as follows: ① In the background maintenance machine detection, the substation assigns the main station address to the background maintenance machine as its local connection address, and assigns the sub station address to the PING address. However, the sub station address is only responsible for detecting the lower end channel and cannot play a corresponding role in the upper end channel.

In addition, tools such as laptops and network cables must be used in the detection of backend maintenance machines. The sub station address should be assigned to the laptop as its IP address, and the laptop should be connected to the backend maintenance machine using a network cable to carry out effective maintenance work In the detection of integrated switches, both lower end detection and upper end detection usually occur. During the upper end detection process, if the detection result shows normal operation, it can be determined that the abnormal problem is occurring in the lower end detection device. In addition, in the upper end detection, it is also necessary to use tools such as laptops and network cables to assist in completing the task. The IP address of the substation is assigned to the laptop as its IP address, and the network cable is used to connect the laptop to the integrated switch for IPNG interaction, achieving detection of the upper end and determining whether the lower end device is operating normally.
