Problems solved by technology

[0004] However, the communication platform used in the existing technology does not take into account similar functions such as operation and maintenance and safety redundancy. These functions are often completed by other modules relying on the communication platform, so the system complexity is high and the system stability is poor.

Embodiment Construction

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] At present, the automatic train monitoring system sometimes has a sudden high frequency of input data due to network communication failures or attacks. If the system does not perform automatic processing, a large amount of data will make the process of the equipment unable to complete all tasks on time, resulting in a low response speed of the equipment. lead to ...

Abstract

The embodiment of the invention provides a shared communication platform of an automatic train monitoring system. The shared communication platform of the automatic train monitoring system comprises aplurality of access devices, each process of each access device corresponds to a plurality of shared memory blocks, and the access devices communicate data written by the shared memory blocks in a multicast mode. According to the shared communication platform of the automatic train monitoring system provided by the embodiment of the invention, the system complexity is reduced and the system stability is improved through a sharing mode taking data storage in the shared memory block as a core.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of rail transit, in particular to a shared communication platform of an automatic train monitoring system. Background technique [0002] The automatic train monitoring system of urban rail transit is a distributed system with a high degree of automation. As a distributed system, a large amount of information is transmitted inside and between each device in the system. Usually, the collection, transfer and transmission of these information Work is usually carried out by a communication platform within the system. The operating mode, performance, and scalability of the platform affect the software and hardware requirements, throughput performance, new function development, maintenance, and redundancy of the entire system. [0003] In the prior art, the automatic train monitoring system needs to collect many types of information, the speed of change is fast, and the amount of informat...
