Abstract

The invention discloses a state monitoring method of a distribution automation wireless public network communication system. The state monitoring method comprises the steps that a communication protocol is added between a distribution terminal and a wireless data transmission module, a CPU in the wireless data transmission module frequently issues AT instructions to obtain state data of a communication module, meanwhile, the CPU records the state data of the wireless data transmission module, the distribution terminal regularly and frequently issues state calling frames to the wireless data transmission module through the communication protocol, the wireless data transmission module correctly recognizes and receives the data calling frames, then replies state response frames to the corresponding distribution terminal and sends the state data to the corresponding distribution terminal according to the communication protocol, and the distribution terminal stores and analyzes the state data after obtaining the state data to judge the communication state of the distribution automation wireless public network communication system. By means of the state monitoring method, abnormal communication events of the distribution automation wireless public network communication system can be recorded and analyzed 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...
