A kind of interface method of MTU depot controlled central system and signal systemTechnical field
The present invention relates to railway signal system Interface design fields, and in particular to a kind of the controlled central system of MTU depot withThe interface method of signal system.
Background technology
On traditional concept, high ferro signal system includes mainly dispatching concentration (CTC), interlocking, occlusion, row control, Centralizing inspectionSubsystem.MTU depot in emerging control central system (CCS) by completing obtaining for Train operation plan with the interface of signal systemIt takes, train route control command is assigned etc. and the relevant automatic control function of signal system.
Wherein, for CTC：High-speed railway, including Line for Passenger Transportation, inter-city passenger rail are generally provided with dispatching concentration (CTC)System.It is it is a kind of local train and shunting service are commanded and are managed, by interlocking, arranging control, track block etc.Signalling arrangement realizes central controlled railway signal technology equipment.The system by dispatch institute central apparatus, station extension facility andWide area network forms.CTC extension facilities that MTU depot can be arranged at present, section institute in shunting route managed by MTU depot, section instituteIt connects departing trains route and is included in centralized management in the transport project of scheduling institute.
CTC system is provided with person on duty and signalman's terminal, electricity business maintenance terminal AT STATION, for driving, signal in stationPersonnel use.CTC system has " dispersion self-discipline " and " very station control " two kinds of control models, and the conversion of control model is in signal systemInterlocking subsystem facilities control console on operated, control model conversion operation or be shown in interlocking and CTC terminals allThere is corresponding state indication lamp.
Wherein, for CCS：MTU depot (institute) control central system (CCS) is to be directed to MTU depot institute motor-car inspection dimension in recent yearsRepair management automation, multiplexing kind operation concert rationality, the maximized transportation demand of operating efficiency and a set of calculating developed and usedMachine system, it be MTU depot institute in scheduling, operator on duty to MTU depot institute in signalling arrangement carry out centralized control, to train workThe railway modernization technical equipment directly commanded with shunting service, managed.In MTU depot institute, CCS and CTC planning management,Traffic order management, access way control etc. function are overlapped.
CCS has " centralized control " pattern and " very station control " pattern, and wherein focus control mode is to realize route by CCSPattern that is automatic and manually handling.The conversion of control model is operated on interlock system facilities control console, and control model turnsThe operation changed is shown in interlocking and CCS terminals and has corresponding state indication lamp.
In the prior art, CCS technical conditions provide its with CTC system into line interface, as shown in Figure 1, physical interface modeFor：CCS systems by MTU depot in be arranged the stations CTC extension set into line interface, and by CTC further with interlock system intoLine interface realizes assigning for access way control order.
The information exchange flow for the CCS and signal system that the prior art provides, as shown in Fig. 2, CCS and signal system at presentInformation interaction flow as shown in dashed line in figure 2, specifically interactive information includes：1) CCS to CTC system send report point,It signs for, the information such as control command, and the information such as wireless dispatching order are forwarded through CTC system.2) CTC sends train operation to CCSPlan for adjustment, traffic order, the expression of neighboring station yard, time synchronization, this section (institute) interlocking code bit, temporary speed limitation, state of a control, nothingThe reception of line traffic order and the information such as sign for.3) both sides transmit mutually advance notice of despatching a train and response message.4) train from section intoBefore entering MTU depot (institute), CTC system sends running number information to CCS systems；CCS sends MTU depot (institute) to CTC and is parked in hairTrain number's information on line.5) CCS sends control command to CTC, while the control command is transmitted to computer and joined by CTCLock system.
During the work time, it is provided in the MTU depot institute of CCS, under normal circumstances, person on duty and signalman's use are set toThe CCS operation control terminals in scheduling hall work, and " concentrate and manipulate " pattern using CCS systems, CTC system is as CCS and signalThe interface equipment of system simultaneously forwards wireless dispatching order for CCS, it is necessary to which booting uses.Therefore, the pattern of dual system is havingAt least there is a problem of in the utilization of body following：
(1) CTC disperses the concentration steer mode that autonomy pattern need to carry CCS
Interlocking of signals system is not changed for CCS about the conversion of control model at present, to interlock systemSpeech, control model still only have " dispersion self-discipline " and " very station control "；After CCS is enabled, CTC is needed " centralized control " of CCSIt is translated as the control model status information of " dispersion self-discipline " pattern and interlock system intercorrelation, it is ensured that each system runs well.This processing mode increases the work load of CTC system, increases the coupling between CTC and CCS systems, is unfavorable for system moduleChange design；CTC " dispersion self-discipline " and CCS " centralized control " operating mode do not demarcate clearly, rely on management according to sceneSystem determines.
(2) mutually card is not implemented with CCS system operation control terminals in CTC
From the requirement of the technology of CTC and CCS, CTC and CCS are by interlock system transform mode control, compartment systemIt is no to be in " very station control " pattern, between CTC and CCS and the switching of different control models and mutual card is not implemented, when system is not " non-Under pattern, CTC and CCS system equipments can be used for often station control ", and when improper use can bring failure or mistake to system.
(3) operation control terminal of CTC is idle
In terms of CTC and CCS device configuration situations, after enabling each monitor terminals of CCS as working equipment, CTC is configured eachType terminal device does not use under normal circumstances.Scene is by Plant management systems at present, when CCS is worked normally, by these endsEnd seal lock is idle to ensure that CTC terminals will not interfere normal utilization.One side equipment investment repeats, is unfavorable for filling for resource in this wayDivide and utilizes；On the other hand the normal with the guarantee for depending on Plant management systems of CCS systems is also resulted in.
(4) the execution link of train operation plan increases
Train operation plan to train route when CCS systems is not used to handle the experience centers CTC --- stations CTC --- connection3 links of lock device；But it can see from the red zone arrow lines of Fig. 2, after CCS systems, train operation plan is from productionIt is raw to train route handle experienced the stations CTC are reached under the centers CTC, the stations CTC are intended to be transmitted to CCS, CCS by trainRoute order is generated after plan and shunting plan synthesis from EMU information management system, route order is issued CTC by CCSIt stands machine, route order is transmitted to 5 links of interlock device by CTC machines of standing, and the wherein stations CTC extension set is as information terminal, and twoSecondary transmitting-receiving relevant plans or route order.This kind of information flow mode increases CTC system information processing complexity, is unfavorable forThe stability of system.
(5) two Inter-System Informations interact the limited utilization risk brought
When CCS is used, the operation in parallel of the stations CTC extension set, but according to CCS technical conditions, in the information of the two interactionLimit is had, for example, the station track between CCS and CTC in not interactive shunting badness label, station track block, station track power failure, Train operation planNumber etc. information, therefore, if because of a certain system therefore switching control is needed to weigh in two systems, since the two information is asynchronous, meetingMake operation personnel use to get muddled.
