Embodiment Construction

[0011] Combine below Figure 1 to Figure 4 Shown, the present invention is described in further detail.

[0012] Such as Figure 1 to Figure 2 As shown, this embodiment discloses a computer interlocking system based on execution module redundancy, the system includes an interlocking machine layer 10 and at least one communication and execution subsystem 20, and the communication and execution subsystem 20 includes a master-backup relationship Two communication machines, one series of executive modules respectively mounted under the two communication machines, and one series of executive modules respectively mounted under the two communication machines are connected in parallel to the outdoor device 30 .

[0013] It should be noted that the interlocking carrier 10 and the communication and execution subsystem 20 in this system all adopt a redundant design, and the interlocking carrier 10, the communication machine and the execution module all adopt a two-out-of-two implementat...

Abstract

The invention discloses a full-electronic computer interlocking system based on redundancy of executive modules and belongs to the technical field of computer interlocking. The full-electronic computer interlocking system comprises an interlocking machine level, a communication machine level and an executive module level. As for a host-backup system, two communication machines and the multiple executive modules connected with the communication machines form a communication and execution subsystem. One interlocking system can be provided with the multiple communication and execution subsystems according to the scale of a station. The interlocking machine level and the communication machine level are connected in a crossing redundancy mode, and the two-line executive modules in the communication and execution subsystem are connected in parallel and then connected to outdoor equipment. According to the full-electronic computer interlocking system, the interlocking machine level, the communication machine level and the executive module layer connected below the communication machine level form the redundant relationship of the host-backup system, and the usability of the computer interlocking system is improved.

Description

technical field [0001] The invention relates to the technical field of computer interlocking, in particular to an all-electronic computer interlocking system based on redundant execution modules. Background technique [0002] At present, the all-electronic computer interlocking system used in the railway signal field usually adopts the main-standby redundancy scheme in the interlocking machine layer and the communication machine layer, but does not use the main-standby system redundancy scheme in the execution module layer, and the interlocking There is no crossover redundancy between the aircraft carrier and the communication carrier. The purpose of this design is to save costs and reduce the difficulty of implementing the computer interlocking system. [0003] However, the design method of the existing computer interlocking system has relatively serious defects: First, it reduces the availability of the computer interlocking system, because if the execution module does not...
