Electronic modularized control system of multi-locomotive traction turnout

Abstract

The invention provides an electronic modularized control system of a multi-locomotive traction turnout. The system comprises N groups of switch machine control modules and an interlocking machine controller area network (CAN) communication channel, wherein each switch machine control module comprises a turnout control unit, an input and output interface circuit, an action state circuit and a switch machine driving circuit; the turnout control unit is connected with the input and output interface circuit and the action state circuit; the input and output interface circuit is connected with the switch machine driving circuit; the N groups of switch machine control modules are connected with the interlocking machine CAN communication channel respectively; the action state circuit of the first group of switch machine control modules is connected with the input and output interface circuit of the second group of switch machine control modules; and according to the order of connection, the action state circuit of the (N-1)th group of switch machine control modules is connected with the input and output interface circuit of the Nth group of switch machine control modules. The control system has the advantages that the system can be scientifically controlled, operates stably, is safe and reliable, and can be easily popularized and applied, and the conventional equipment is easy to reconstruct.

Description

technical field [0001] The invention relates to an electronic modular control system for a multi-machine traction turnout, which belongs to the technical field of railway signal control. Background technique [0002] At present, 6502 execution circuit is commonly used in the execution layer of microcomputer interlocking on railways. The control of multi-machine traction turnout by 6502 execution circuit is mainly that the microcomputer interlocking issues a fixed operation command or reverse operation command, and all the traction machines of the turnout start in sequence. Each action, the 6502 executive circuit completes the logic control between each traction point; there are also individual stations on the railway that use electronic executive equipment, and electronic executive equipment is the development direction of interlocking executive equipment in the future. Issue commands, and the microcomputer interlock realizes the logic control between each traction point; fo...

[0002] At present, 6502 execution circuit is commonly used in the execution layer of microcomputer interlocking on railways. The control of multi-machine traction turnout by 6502 execution circuit is mainly that the microcomputer interlocking issues a fixed operation command or reverse operation command, and all the traction machines of the turnout start in sequence. Each action, the 6502 executive circuit completes the logic control between each traction point; there are also individual stations on the railway that use electronic executive equipment, and electronic executive equipment is the development direction of interlocking executive equipment in the future. Issue commands, and the microcomputer interlock realizes the logic control between each traction point; for the microcomputer interlock equipment, the corresponding program needs to be modified according to different execution units. If the microcomputer interlock manufacturer and the electronic interlock execution equipment manufacturer have not cooperated before, It may delay the opening time of station equipment; in addition, the equipment of different manufacturers needs to be updated, which will directly affect the cooperative use of equipment, so it is not conducive to the promotion of interlocking electronic execution units
