Abstract
A railway monitor system for monitoring the existing electrically centrallized interlocking equipment "6502" to prevent error switching is composed of multimedia computer and signal-collecting processor for the "6502". With said system, the traditional manual inter-control mode for the "6502" is changed to prevent error operation caused by artificial factor. The normal operation of system "6502" is not affected by it. The graphic interface of system has object display and is convenient operation. Under the support of computer software, operator can add and modify the train schedule and time at any time.
Description
The present invention relates to a kind of computer supervisory control system, be specially railway monitor system for preventing error switching, be used for monitoring existing 6502 electrical interlocking equipment of railway.
6502 electrical interlocking equipment are a kind of electric horn interlocking apparatus that the present railway system generally adopts.In use,, produce mistake and do, cause serious consequence because human element often causes maloperation.At present, mistake proofing is done and is only limited to a thing and orders a system, makes an issue of on human elements such as rules and regulations, sense of responsibility.Because 6502 electrical interlocking equipment are Ministry of Railways's approved products, be safety, the reliability that guarantees its operation, at present, do not allow carrying out the reconfiguration on any circuit, direct lead-in wire on this interlocking equipment, this gives technological means and this interlocking equipment is carried out operation supervise and control brings difficulty: therefore, at present the railway system finds no at the mistake proofing of 6502 interlocking equipments and does monitored control system or control monitor unit, or has control monitor unit also to be only limited to the monitoring of form such as voice suggestion.
Purpose of the present invention does not have the railway monitor system for preventing error switching that directly is electrically connected with 6502 electrical interlocking equipment for providing a kind of.
The present invention adopts following measure to realize: this monitored control system comprises the computing machine that has the multimedia preparation, between computing machine and 6502 interlocking equipments, be provided with a signal acquisition process device, this signal acquisition process device is with the form of the non-direct electrical connection top from 6502, gather relevant station track on the final impulse optor program, the signal of direction, link to each other with computing machine by standard interface, simultaneously, by this signal acquisition process device control, be provided with a relay switch device, this relay switch device is design-calculated electromechanical element voluntarily, its characteristics are the contact of existing relay is opened, close action and replace mechanical movement by the power-actuated corresponding sports parts of relay electromagnetism, this movable parts is used to realize mechanical latching and the unlatching to departure route direction the corresponding button.Its total working process is: the signal acquisition process device will be changed and handle from the signal of the 6502 relevant station tracks that collect, direction, pass to computing machine through interface, under the support of corresponding software, contents such as this signal and train number, time are shown at computer display.Train when specific station track needs to send to specific direction, the watch keeper sends instruction by computing machine, this instruction feeds back to the signal acquisition process device, it controls the action of corresponding relay switch device, cooresponding arrow button is become unlatching by the mechanical latching of normality, like this, the signalman can be to the corresponding button normal running, at this moment, because other arrow button still is in the mechanical latching state, can not produce maloperation.On the contrary, if the signalman finds that the instruction that the watch keeper provides is wrong, but also notify the watch keeper to correct during the utmost point.This shows that this monitored control system has been set up a kind of mutual prison cross complaint relation between watch keeper and signalman.And, because it does not produce and anyly directly to be electrically connected with 6502, do not violate the safety standards of relevant 6502 operations, be easy to promote the use of this point creative place also of the present invention just.
Monitored control system utilization computer control principle of the present invention is realized the operation supervise and control to existing 6502 equipment effectively, has changed the mode of operation of traditional for many years artificial cross complaint, has reduced the maloperation that human element causes, and reaches the purpose that mistake proofing is done.Total system does not influence the normal operation of 6502 electric horn interlocking apparatus.System's figure interface display is directly perceived, convenient, and easy operating, is waited to send out train and route setting process etc. and can both intuitively be shown on telltale train number, time of departure, starting direction, track occupied.Under the support of corresponding computer software, the watch keeper can add at any time, revise contents such as train number, time, and operation all has complete record each time, is convenient to check analysis in the future.
