Online communication method based on protocol configuration

Abstract

The invention discloses an online communication method based on protocol configuration. The method comprises the following steps of configuring communication protocols into a frame type, a frame format and an enumeration type, and analyzing the network message according to the frame type, the frame format and the enumeration type. The protocol is configured and analyzed according to the frame type, the frame format and the enumeration type; the protocol analysis becomes universal, stable and convenient, the development workload related to the communication protocol analysis can be greatly reduced, and the release frequency of the system caused by protocol content change is reduced, so that the reliability, usability and maintainability of the whole software are improved. Through a protocolconfiguration method, the online communication method has better applicability under the condition that communication protocols and data analysis methods among different systems are different, so that the online communication method can be applied to more systems, and the expandability and the flexibility of online diagnosis software of an urban rail transit signal system are greatly improved.

Description

Technical field [0001] The invention relates to the field of rail transit 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, and generally uses UDP or TCP / IP for information collection, data analysis, data storage and information display for one or more equipment. For equipment of different systems, different communication protocols and different analysis methods are required. These methods have the following shortcomings: [0003] The protocols between different systems and online diagnostic software are different, and their data analysis methods are also different. Once the protocol or system is updated, the relevant analysis and implementation must be modified, which is time-consuming and laborious; [0004] The same system may add, delete or modify the content of the agreement during the ...

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
