Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is binary channels secondary-confirmation schematic diagram；
Fig. 2 is anti-timeout mechanism schematic diagram.
Embodiment
As shown in figure 1, a kind of urban railway transit train based on independent binary channels secondary-confirmation mode monitors and is automatically
System, including be used for issuing the first dispatcher workstation of operation requests, second as secondary-confirmation terminal by operator is selected
Dispatcher workstation and station/communication server, first dispatcher workstation simultaneously to the second dispatcher workstation and
Station/the communication server sends operation requests, and operation requests are sent to CBI/ZC and by CBI/ by the station/communication server
The confirmation request of ZC feedbacks is sent to the first dispatcher workstation and the second dispatcher workstation, second dispatcher workstation
Confirm module and manual confirmation module provided with machine, second dispatcher workstation confirms module and manual confirmation mould in machine
After block confirms to confirmation request, operation acknowledgement instruction is sent to CBI/ZC through station/communication server.
The technical solution adopted by the present invention, using combined fault-safe practice, the operation requests of safety operation and operation are true
Recognize and realized by completely self-contained two passages.
Issue first and the secondary-confirmation of safety operation are supported to use two-machine operation mode.Two operating personnel must be each
From work station on confirm the display of operation requests and operation acknowledgement respectively, and confirm the display of security command operating result.With
Specified in the work station of secondary-confirmation by the operator for issuing operation requests.
User initiates the first dispatcher workstation of security function request, and confirms the second dispatcher work of security function
To stand, be two different work stations, two chassis stations/communication server is respectively used to transmit operation requests and operation acknowledgement order,
Ensure request and confirm it is two independent physical channels.
ATS work stations provide two kinds of different display sides to the secondary-confirmation and returning result of safety-related command operation
Formula.Only allow an operator to carry out security related operations to same target in the same time, it is right to this to refuse other operators
The operation requests of elephant.
In addition, adding anti-timeout mechanism, user's secondary-confirmation should have time restriction, if not confirmed within the time limit
Operation, ATS automatically exits from safety operation process, and reminds user.As shown in Fig. 2 work station, which is responsible for protection, sends operation requests
It is specific as follows to the time-out for receiving the confirmation request period：
First dispatcher workstation sends operation requests to server and the second dispatcher workstation simultaneously, and starts to count
When, the second dispatcher workstation starts timing when receiving operation requests.Confirmation request will issue simultaneously the first dispatcher workstation,
Second dispatcher workstation, the first dispatcher workstation and the second dispatcher workstation are all compared to time-out, the first scheduling
Work station will whether overtime result issues the second dispatcher workstation to member, people's dispatcher workstation according to two not time-out informations
Acknowledgement window is ejected, now whether overtime artificial (operator) must reaffirm.
CBI, ZC must decide whether to from operation requests are received, to the time for receiving confirmation request, whether time-out judges
Perform final operation.
The instruction of the operation requests, confirmation request and operation acknowledgement needs to generate 32 CRC check codes in transmitting procedure,
And be packaged in efficient message body, it is specially：
Increase sequence number, processing field in application layer messages, increase sequence-number field in host-host protocol, prevent repeatedly,
Delete, be out of order；
By message feedback, ATS compares whether confirmation request is consistent with operation requests information, and CBI/ZC compares operation requests
It is whether consistent with operation acknowledgement, and sequence number in application message and host-host protocol prevents message from inserting；
Application layer critical data is verified using CRC32, and security protocol prevents message mistake using encryption technology；
Prevent message from pretending by the encryption of message feedback, and security protocol.
For the more preferable explanation present invention, concrete principle is described as follows：
When operator selects a work station to issue operation requests, the terminal of secondary-confirmation need to be specified, is selected in the present invention
Fixed first dispatcher workstation issues operation requests, the second dispatcher workstation as secondary-confirmation terminal, while the work station
Operation object on interface should be marked with different states, and be prompted in a text form.
Before instruction is sent, 32 CRC check codes are generated to corresponding information position, and be packaged in efficient message body.Behaviour
Make request and issue station/communication server and selected operation acknowledgement work station simultaneously.Operation requests work station sends operation please
Start timing when asking instruction, operation acknowledgement work station starts timing when receiving operation requests information.
Station/communication server is operation requests passage or operation acknowledgement passage according to configuration differentiation.Instruction reaches behaviour
After making station/communication server of request channel, terminal, the place of station/communication server record operation requests and operation acknowledgement
The information such as reason number, message body is then subjected to security protocol encapsulation, and is sent to CBI/ZC.
When station/communication server of operation acknowledgement passage receives CBI/ZC confirmation request, station/communication server enters
Row security protocol is unpacked, and further according to the operation acknowledgement terminal recorded in message, message is sent to set operation acknowledgement terminal.
Operation acknowledgement terminal is unpacked and CRC check, judges whether confirmation request is identical with operation requests and whether surpasses
When, operation requests terminal will whether overtime result issues operation acknowledgement terminal, and what the latter judged according to itself having not timed out and grasping
Information ejection secondary-confirmation window is had not timed out as what requesting terminal was sent, user carries out operation acknowledgement.
Operation acknowledgement terminal will generate 32 CRC check codes to confirmation, and be packaged in efficient message body, issue behaviour
Make station/communication server of confirmation passage.
After instruction reaches station/communication server of operation acknowledgement passage, security protocol encapsulation is carried out, and be sent to CBI/
ZC。
When the operating result for receiving CBI/ZC, operating result is transmitted to operation terminal by station/communication server.
