A communication link guarantee method based on industrial wifi

Abstract

The invention discloses a communication link assurance method based on industrial WIFI. A new communication protocol is added on the basis of a TCP communication protocol, each type of data frame can be reconstructed according to the new communication protocol even if a transmitting end transmits to a data receiving buffer of a receiving party in the order of byte stream, the type of each data frame is identified, and the completed data frames are parsed according to received byte data; and then to which functional module of the system the data of each data frame should be delivered for processing is determined according to the different types of the data frames. The method of the invention aims at an abnormal situation that may appear during the inspection of a robot, and improves the fault tolerance of the data transmission of a communication link through a certain abnormal communication condition recovery algorithm on the software of the two ends of the communication.

Description

technical field [0001] The invention belongs to the technical field of communication links, and in particular relates to a communication link guarantee method based on industrial WIFI. Background technique [0002] Electric power safety production is the premise and basis for the development of electric power industry, and the operation management of substation is an important part of electric power safety management. At present, the daily operation and maintenance of most substations in my country adopts the method of manual inspection, using handheld devices or manual meter reading to record the faults of each equipment in the substation in turn. In order to overcome the problems of large number of inspection equipment, various types of inspection equipment, and high cost of manpower input in the process of manual inspection, some substations have to update power equipment and instruments, and convert the operating status of on-site equipment in substations into digital si...

AI Technical Summary

Problems solved by technology

[0003] However, substations are generally located in remote suburbs. Substations are large in scope, strong in electromagnetic interference, and have problems such as communication obstacles. In addition, the data types communicated between the inspection background monitoring system and the robot itself have the characteristics of multiple types and large data volumes. The data transmission between the background control system and the robot body is unstable

At the same time, the working environment of the robot is an outdoor unattended automatic substation, so when an abnormality occurs during the communication process, it cannot be processed on the software control at both ends of the communication, and the connection status of the data communication link is unstable.
