Abstract

The invention relates to a scattered equipment driving system for rail transit signal control, the system comprises a logic processing subsystem, a maintenance diagnosis subsystem, scattered driving modules and a safety communication processing module, and the scattered driving modules, the safety communication processing module and the logic processing subsystem are connected in sequence. The safety communication processing module is connected with the maintenance diagnosis subsystem; control commands of the scattered equipment are converted into control commands by the logic processing subsystem according to Boolean logic and the control commands are transmitted to the safety communication processing module through a redundant safety network, and the safety communication processing module distributes the control commands to the corresponding scattered driving modules according to configuration. And the scattered driving modules drive the corresponding scattered equipment according to the obtained driving commands, and uploads the maintenance detection information of the board card to the safety communication processing module so as to transmit the maintenance detection information to the maintenance diagnosis subsystem. Compared with the prior art, the system has the advantages of reduced circuit volume and cost, timely alarm, convenient field maintenance and the like.

Description

technical field [0001] The invention relates to a rail traffic signal control system, in particular to a scattered device drive system for rail traffic signal control. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, more and more types of rail transit have emerged, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. [0003] The existing rail transit signal control system includes a variety of scattered equipment. In order to realize the communication between various equipment, it is necessary to build more complex relay circuits and monitoring circuits, which requires more relays and monitoring circuits in actual design and construction. ...
