ATS protocol forwarding processing system and method based on protocol library

Abstract

The embodiment of the invention discloses an ATS protocol forwarding processing system and method based on a protocol library. The system comprises that the message producer produces a data packet according to a protocol format specified by the message receiver and sends the produced data packet to the message server; the data packet is forwarded to a message receiver by the message server, a library identifier is analyzed from the data packet by the message receiver after the message receiver receives the data packet, and a first dictionary is queried according to the library identifier to obtain a protocol header type and a protocol number; and the message receiver queries a second dictionary according to the protocol number, obtains a protocol type corresponding to the protocol number,and analyzes the protocol body from the data packet. According to the embodiment of the invention, an ATS system protocol forwarding service based on a protocol library mode is used as a core; unifiedmanagement, subscription and distribution services of ATS system protocols are achieved, the defects that the system is not easy to maintain and expand due to diversity and complexity of the protocols are effectively overcome, and the pressure of different subsystems on interface protocol forwarding services is reduced.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to an ATS protocol forwarding processing system and method based on a protocol library. Background technique [0002] ATS system (Automatic Train Monitoring System), as one of the core systems of CBTC system (Automatic Train Control System Based on Wireless Communication), undertakes important tasks such as route control, operation diagram adjustment control, train monitoring and information transmission. The ATS system contains multiple subsystems, which exchange information through two-way communication and work together to realize the important function of train monitoring. However, communication within the system needs to use multiple different protocols at the same time, and the protocol forwarding mechanism is complicated. [0003] In the development process of the ATS system, in order to adapt to different engineering projects and needs, multiple versions of communicat...

AI Technical Summary

Problems solved by technology

[0006] 1. There are many connection links between various subsystems and sub-subsystems, resulting in low communication efficiency;

[0007] 2. The communication protocol will be defined separately between each subsystem and sub-subsystem. As a result, there are many types of protocols, the difficulty of software development and debugging, and the increase of product development and maintenance costs;

[0008] 3. The system has poor scalability and is difficult to cope with changing needs
