Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039] see image 3 , the remote shaft recording pre-reset system of the present invention includes ATS server, PLC, ACE, PMI and relay group, wherein:

[0040] The ATS server is connected to PMI and PLC respectively through Ethernet; PLC is connected to ACE; each relay coil in the relay group is respectively connected to PMI, and each normally open contact is connected in series between the power supply and PLC.

[0041] The ATS server is used to output the remote axle counting pre-reset command; the PMI receives the remote axle counting pre-reset command, drives each relay in the relay group to keep the high position to connect the power supply and PLC, and returns;

[0042] According to the recovery signal of PMI, the ATS server sends the remote axle counting pre-reset command to the PLC after knowing that each relay in the relay group is in a high state;

[0043] PLC ...

Abstract

The invention discloses a remote axle-counting preliminary reset system which comprises an ATS (Automatic Train Supervision) server for outputting a remote axle-counting preliminary reset command, a power supply, an ACE (Axle Counter Evaluator), a PLC (Programmable Logic Controller), a relay unit and a PMI (Computer Based Interlocking System), wherein the remote axle-counting preliminary reset command is used by the PLC to control the ACE to execute preliminary reset; all relay coils of the relay unit are respectively connected with the PMI; all normally-opened contacts are sequentially connected between the power supply and the PLC in series; the PMI receives the remote axle-counting preliminary reset command, drives all relays in the relay unit to maintain high orders and further the power supply the PLC are connected and extracted; the ATS server is informed that all the relays in the relay unit respectively maintain the high-order state according to an extraction signal of the PMI, and transmits the remote axle-counting preliminary reset command to the PLC. According to the remote axle-counting preliminary reset system disclosed by the invention, the PMI is used to replace the actions of persons on duty, so the safety and the reliability are realized, and the risk caused by manual operation is avoided.

Description

technical field [0001] The invention relates to the field of train monitoring, in particular to a system and method for recovering the state of a disturbed axle counter block ACB (Axle Counter Block). Background technique [0002] Currently, the axle counting equipment communicates with PMI (Poste de Manoeuvre Informatisé (Computer Based Interlocking system), computer interlocking subsystem) through the discrete I / O ports of ACE (Axle Counter Evaluator, axle counting evaluator). The axle counting device counts the number of train axles passing a certain position in a certain direction, and each axle counting device reports to ACE the number and direction of the axles passing by its position every 200 milliseconds, and then ACE calculates the number and direction of the train axles passing by its location according to the All axle counting equipment in the system count and calculate the occupancy of ACB (Axle Counter Block, axle counting section), and report the result to PMI...
