An online communication method based on protocol configuration

Abstract

The invention discloses an online communication method based on protocol configuration. The method includes: configuring a communication protocol into three parts: frame type, frame format and enumeration type; and parsing network messages according to the frame type, frame format and enumeration type. The present invention configures and parses the protocol according to the frame type, frame format and enumeration type respectively, so that the protocol parsing becomes universal, stable and convenient, and the development workload related to the parsing of the communication protocol can be greatly reduced, and the system can be reduced due to the content of the protocol. The number of releases resulting from changes, thereby improving the reliability, ease of use, and maintainability of the entire software. Through the protocol configuration method of the present invention, the online communication method has better applicability when the communication protocols and data analysis methods between different systems are different, so that it can be applied to more systems and greatly improves the Scalability and flexibility of online diagnostic software for urban rail transit signal systems.

Description

technical field [0001] The invention relates to the field of rail traffic signal systems, in particular to an online communication method based on protocol configuration. Background technique [0002] The online diagnostic software in the rail transit signal system communicates with the equipment through the network, generally through UDP or TCP / IP, for information collection, data analysis, data storage and information display for one equipment or multiple equipment. For devices of different systems, different communication protocols and different parsing methods need to be used. These methods have the following shortcomings: [0003] The protocols between different systems and online diagnostic software are different, and the data analysis methods are also different. Once the protocol or system is updated, the related analysis and implementation must be modified, which is time-consuming and labor-intensive; [0004] The same system may add, delete or modify the content of...

AI Technical Summary

Problems solved by technology

[0003] The protocols between different systems and online diagnostic software are different, and the data analysis methods are also different. Once the protocol or system is updated, the relevant analysis and implementation must be revised, which is time-consuming and laborious;

[0004] The same system may add, delete or modify the content of the agreement during the iterative update process of the product, which will cause the online diagnostic software to continuously iterate with the system, resulting in poor flexibility
