Background technology
Country metro project part circuit has Liang Ge control centres at present, i.e., primary control centre (OCC) and spare control
Center (BOCC) processed.The setting up of spare control centre mainly considers primary control centre's equipment fault and the standby scene of calamity, so as to
Complete not available (such as primary control centre's dead electricity, fire, earthquake, war etc.), the Ke Yiyong in primary control centre
Spare control centre organizes metro operation, is unlikely to that operation is made to interrupt.Come particularly with the unmanned circuit of fully automatic operation
It says, since the running command of train all concentrates on control centre's control, the effect of spare control centre is more important.
But there is certain defect in current spare control centre, the switching efficiency after emergency generation in use
It is relatively low, it is primarily present the deficiency of following several respects：
1, since trackside equipment and train can only be commanded simultaneously by a center, and OCC and BOCC are relations on an equal basis,
Also based on this design requirement, OCC and BOCC are provided that identical address.For signal system, at the same cannot there are two
Center is commanded, if OCC and BOCC is online simultaneously, can cause command collision and signal system is caused to can not work normally.Therefore,
When normal operation, the network of BOCC needs to disconnect；When OCC failures can not be restored, connect again after needing the network connection of disconnection OCC
Enter the network of BOCC and is switched with completing active and standby center.
2, since control centre's equipment is more, and interface is more, therefore still cannot achieve multi-specialized synchronous automatic switchover.
3, switching needs manpower intervention；
4, switching efficiency is low, influences the fast quick-recovery operation of system.
5, human factor is considered, switching time was at 10 minutes or more.

Specific implementation mode
Technical solution in the embodiment of the present invention is carried out below clear, is fully described by, it is clear that described implementation
Example is a part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiments of the present invention, ordinary skill
The every other embodiment that personnel are obtained without making creative work should all belong to the model that the present invention protects
It encloses.
As shown in Figure 1, the long-range handoff procedures of OCC-BOCC of the present invention：
Center is set there are two switching control terminal A and B.Two control server As and B.OCC and BOCC is respectively equipped with two
Hardware control A and B.OCC exchanger powers are disconnected by hardware control, and the power supply for opening BOCC interchangers realizes OCC
With the switching of BOCC, operating process is as follows：
1. center operations staff executes OCC-BOCC switching control orders on switching control terminal A machines；
2. the order will be sent to remote control server A, then be sent to OCC/BOCC hardware by remote control server
Controller A；
Random to generate command checksum code after 3. hardware control A receives the control command.Remote control hardware A respectively will
Command checksum code is sent to remote control hardware B and is sent on remote control operation terminal A machines along former communication link；
4. center operations staff can obtain the command checksum code；
5. center operations staff executes switching control order, and input validation code on remote control terminal B machines；
6. the control command will be sent to OCC/BOCC hardware controls B；
7. remote hardware controller B carries out remote control terminal B machines and remote control hardware A the command checksum code generated
It compares, if the two unanimously just thinks that order is effective；
8. being initially switched off the exchanger power of OCC after order effectively, it is then turned on the exchanger power of BOCC after delay, completes
Handoff procedure.
9. after the completion of switching, BOCC can be shown in Fig. 3 and Fig. 4 with normal control station LATS.
The exchanger power at primary center can be remotely closed by hardware control for the switching of active and standby control centre,
And the mode for opening the exchanger power at spare center realizes active and standby center switching demand, to realize hot backup redundancy management.
Handover control system ensures the independence of system using double set software and hardware system designs.In external input order control
In the case of control equipment, the output control logic of duplexed system must assure that unanimously, to ensure accuracy, the reliability of system.
Otherwise, control command is invalid.
On the basis of the design scheme of duplexed system, system builds separate two-way communications network link, ensures
Independence, the isolation of information transmission.
Remote control server realizes two-node cluster hot backup, ensures in the case of a server delay machine, in addition a service
Device is able to maintain that system worked well.
Only after the interchanger of OCC powers off, it could be powered on to the interchanger of BOCC；Vice versa.
As shown in Fig. 2, under normal circumstances, the ATS servers (ATS Server) of OCC pass through network and serial port (heartbeat
Line) judge activestandby state.Host isolated operation of the ATS servers of BOCC as not control.The work of OCC and BOCC
It stands (WS) and display screen is connected with the ATS server hosts of OCC, to obtain layout display.The server of OCC and BOCC is independent
Operation.
As shown in figure 3, after server switches to BOCC, center dispatcher can still be operated in OCC, with realization " people
Motionless equipment is dynamic ".The case where scene is OCC server failures, transmission device partial fault and operating terminal can be used, it is main to cope with
The case where local fault.
As shown in figure 4, after server switches to BOCC, center dispatcher is operated in BOCC, and with realization, " people moves equipment
It is dynamic " scene is OCC server failures and operating terminal also failure, it is main to cope with the standby situation of calamity.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can readily occur in various equivalent modifications or replace
It changes, these modifications or substitutions should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with right
It is required that protection domain subject to.
