Abstract

The invention discloses a state monitoring method of a power distribution automation wireless public network communication system, which includes adding a communication protocol between a power distribution terminal and a wireless data transmission module, and the CPU in the wireless data transmission module frequently sends AT commands to obtain communication The status data of the module, at the same time, the CPU records the status data of the wireless data transmission module itself, and the power distribution terminal sends the status call frame to the wireless data transmission module regularly and frequently through the communication protocol. After the wireless data transmission module correctly recognizes and receives the status call frame , to reply the status response frame to the corresponding power distribution terminal, and send the status data to the corresponding power distribution terminal according to the communication protocol. The communication status of the network communication system. The invention can record and analyze the abnormal communication events of the distribution automation wireless public network communication system in time.

Description

technical field [0001] The invention relates to communication monitoring of distribution automation, in particular to a state monitoring method of a wireless public network communication system of distribution automation. Background technique [0002] Distribution automation refers to the comprehensive utilization of computer, information and communication technologies based on the primary grid and equipment, and through the information integration of related systems, to realize the monitoring, control and rapid fault isolation of the distribution network. [0003] The power grid, especially in the construction of distribution automation, occupies an important position and is an indispensable communication method. If wireless public network communication is required, the power distribution terminal will generally integrate a wireless data transmission terminal (wireless data transmission terminal), with a built-in communication module and card slot, etc., which can realize d...
