Embodiment

[0038] Based on the RS485 bus, the self-adaptive interception and analysis method for the terminal communication of the power Internet of Things, such as figure 1 As shown, the adaptive listening node is set between the master node and the slave node, the method is as follows Figure 2-3 As shown, including the listening step and the parsing step, the listening step specifically includes:

[0039] Step 1, obtain the RS485 bus communication parameter configuration;

[0040] Step 2, set the RS485 bus communication baud rate, data bit, parity bit, stop bit, and start communication message monitoring;

[0041] Step 3, judging whether the message is intercepted, if not, then obtain the new RS485 bus communication parameters, return to step 2, if the message is intercepted, then enter the analysis step;

[0042] The analysis steps specifically include:

[0043] Step 4, judge whether it is a correct message, if it is correct, go to step 6, if it is wrong, go to step 5;

[0044] ...

Abstract

The invention discloses an RS485 bus-based self-adaptive monitoring analysis method for communication of a power Internet of Things terminal, which overcomes the defects in the prior art and comprises a monitoring step and an analyzing step. The monitoring step specifically comprises the following steps: 1, acquiring RS485 bus communication parameter configuration; 2, setting an RS485 bus communication baud rate, a data bit, a check bit and a stop bit, and starting communication message interception; 3, judging whether the message is monitored or not, if the message is not monitored, obtaining a new RS485 bus communication parameter, returning to the step 2, and if the message is monitored, entering an analysis step; after the analysis step is completed, recording the communication parameters of the RS485 bus, and restoring the communication data.

Description

technical field [0001] The present invention relates to the technical field of electric power Internet of Things, in particular to an RS485 bus-based self-adaptive listening analysis method for electric power Internet of Things terminal communication. Background technique [0002] The power Internet of Things is a network system that realizes the identification, perception, interconnection and control of power grid infrastructure, personnel and their environment. Its essence is to realize the combination of various information sensing devices and communication information resources, so as to form a physical entity with self-identification, perception and intelligent processing. The collaboration and interaction between entities enables related objects to perceive and control each other, forming a more intelligent power production and living system. According to statistics, there are currently more than 500 million terminal devices connected to the State Grid system (includi...
