Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0030] Such as figure 1 As shown, the computer interlocking system provided by the present invention includes operator station subsystem (OPS1 and OPS2, Operator Station), history station subsystem (HDS, Historical Data Station), safety interlock computer subsystem (SIC, Safe Interlock Computer ), input subsystem, output subsystem, communication subsystem and interface subsystem.

[0031] The operator station subsystem is composed of dual machines with hot standby redundancy, such as figure 1 OPS1 and OPS2 shown. It is not only the operation monitoring interface of the system, but also the communication gateway between the ATS (Automatic Train Supervision, automatic train monito...

Abstract

The invention relates to a computer interlocking system, which comprises a ground region control center used for real-timely monitoring the train position and outputting the position information of a train; a safe computer interlocking subsystem used for receiving the train position output by the ground region control center, interlocking calculating according to the train position and output a control signal according to the calculation result; an output subsystem used for receiving the control signal output by the safe computer interlocking subsystem and controlling a field device to drive; and a communicating subsystem used for building safe communication connection among the ground region control center, the safe computer interlocking subsystem and the output subsystem. The computer interlocking system has the advantages of suitability for moving block, moving-like block and fixing block with high flexibility; the insurance of safety and reliability of system communication coming from the existence of a standard and safe communication port of the ATS system and ATP system ground ZC; and the support of the three modes of regularity, degradation and backup.

Description

technical field [0001] The invention relates to a computer interlocking control system, in particular to a computer interlocking control system applicable to both the field of railway signal control and the field of urban rail traffic signal control. Background technique [0002] As an important part of the rail transit signal system, the computer interlocking system is well known to everyone. It ensures the safety of train operation by establishing a certain logical relationship between the signal machine, the switch and the approach. [0003] The existing computer interlocking system of the rail transit system is mainly composed of a control display machine, an interlocking machine, an input control module, an output control module and a communication subsystem. Human-computer interaction is performed through the control display machine, and the input control module is responsible for on-site signal The equipment status is collected, and the collected data is output to the...
