Description
Technical field
The present invention relates to train supervision field, particularly relate to a kind of system and the method thereof of recovering disturbed meter shaft section ACB (Axle Counter Block) state.
Background technology
At present, axis-counting device and PMI (Poste de Manoeuvre Informatis é (Computer Based Interlocking system), computer interlock subsystem) communicated by the discrete I/O port of ACE (Axle Counter Evaluator, meter shaft evaluator).Axis-counting device calculates the quantity of a direction through the train axle of certain position, each axis-counting device once passes through quantity and the direction of the axletree of its position every 200 milliseconds to ACE report, then ACE calculates ACB (Axle Counter Block according to the counting of all axis-counting devices relevant to this section, meter shaft section) take situation, by report the test to PMI.
In ACE, all have four kinds of states to each ACB: vacant, take, disturbed and pre-reset.If following condition meets, ACB is regarded as disturbed:
1) ACE suspends; 2) ACE is restarted; 3) communication between check point magnetic head and ACE is disturbed; 4) communication between ACE is disturbed, and this section is the public section of two or all ACE; 5) section is idle, and receives the false alarm of check point; 6) the wheel shaft count value of section is negative; 7) two count values of ACB check point are inconsistent, or detect that the residue in section takes turns the number of axle lower than a threshold value, are identified the wheel number of axle (default value is 1, but can configure) being less than train.
ACB disturbed state shows section fault, will be considered as taking for disturbed ACB, PMI.In order to remove fault, need to follow following formality:
Send pre-reset order to disturbed ACB by ACE, the wheel counting apparatus of this section is all reset.
When following security procedure, artificial mode train or " simulating wheel " two wheel counting apparatus by this ACB can be driven.Before not completing this process, ACB is still in disturbed state.
If the axletree quantity of turnover ACB is again consistent, then disturbed state is eliminated.If quantity is still inconsistent, then ACB still keeps disturbed state, needs another time " pre-reset " to order.
In existing system, there is the mode of two kinds of realizations " pre-reset ".One is that control center member on duty is from ATS (Automatic Train Supervision, train supervises subsystem automatically) send the order of a long-range meter shaft pre-reset to PLC (Programmable Controller, Programmable Logic Controller), the button pressed in control cabin by local watch keeper connects power supply and sends pre-reset order with enable PLC, PLC control ACE to disturbed ACB.As shown in Figure 1 and Figure 2.Another mode is that local watch keeper uses the key switch on parallel input/output board to send pre-reset order to disturbed ACB.Because ACE rack is placed on canyon, this mode just requires that service personnel all will go canyon to operate at every turn, and inconvenience is also dangerous.
Therefore, in current operation, the first pre-reset mode is more conventional.Want the meter shaft section that pre-reset one is disturbed, need to press the button enable PLC by local watch keeper after ATS subsystem command PLC and power.But it should be noted that PLC is not secure subsystem, and this mode all needs watch keeper's action when each meter shaft pre-reset.When there being train occupation in an ACB, pre-reset is carried out in maloperation can be risky.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 3, long-range note axle pre-reset system of the present invention, comprises ATS server, PLC, ACE, PMI and relay group, wherein:
ATS server via Ethernet connects PMI and PLC respectively; PLC connects ACE; Each relay coil in relay group connects PMI respectively, and each open contact is serially connected between power supply and PLC successively.
ATS server is for exporting the order of long-range meter shaft pre-reset; PMI receives the order of long-range meter shaft pre-reset, drives each relay in relay group to keep high-order to switch on power and PLC, and back production;
ATS server, according to the back production signal of PMI, after knowing that in relay group, each relay all keeps high-end trim, sends the order of long-range meter shaft pre-reset to PLC;
PLC performs pre-reset according to long-range meter shaft pre-reset order control ACE.
In the present embodiment, define two relays in relay group, these two relays are identical.Be from security standpoint with two identical relays, the state of expression is more accurate, controls more stable.As seen from Figure 3, the function of these two relays is identical with PLC enable button.PMI controls the output state of these two relays, and back production.(export with back production state inconsistent, and this inconsistent state continues more than 200 milliseconds) when any one relay et out of order, PMI can send one and report to the police to ATS server.According to the state of two relays, PMI sends the status report of back production to ATS server.
When following any situation occurs, PMI can not accept the long-range meter shaft pre-reset order of ATS server:
Any one fault in two relays;
Any one back production state in two relays is high-order.
When following condition all meets, PMI can accept the long-range meter shaft pre-reset order of ATS server:
All et out of order is not had in two relays;
Back production state in two relays is all low level.
Can control center member on duty or ATS server self send the order of a long-range meter shaft pre-reset to PMI from ATS server according to the condition adjudgement of PMI report, if PMI report state is not for accepting, then ATS server command can be left in the basket.
Can represent that the internal logic of this function of PMI designs by utilization state machine figure:
As shown in Figure 4, from logic the design: in 0 state when PMI just starts, without input and output, built-in variable is not had to change yet.After startup, logic state is 1,4,6,8, and PMI can change internal logic states again according to trackside time of day afterwards.
By following steps, state transition is described:
1, if after startup, PMI detects two relays all do not have fault, and two relay status are all low level, then state 8 can jump to 9, namely PMI can accept the initial pre-reset order of ATS, logic state is 1, 4, 6, 9, after now accepting the initial pre-reset order of ATS, state 1 can jump to 2, countdown in 10 seconds is (if state 9 jumps to 8 in countdown, then interrupt countdown in 10 seconds and state 2 is jumped to 1) terminate after state 2 automatically can jump to 3, in 20 seconds afterwards, ATS sends and confirms pre-reset order, state 3 redirect can get back to 1 (extraordinary circumstances 1: if do not receive ATS in countdown in 20 seconds to confirm pre-reset order, after 20 seconds, countdown is invalid, the order of meter shaft pre-reset is also invalid, state jumps to 1 by 3.Extraordinary circumstances 2: if state 9 jumps to 8 when also not receiving ATS confirmation pre-reset order in countdown in 20 seconds, then interrupt countdown in 20 seconds, the order of meter shaft pre-reset is invalid, and state jumps to 1 by 3.), once complete long-range meter shaft pre-reset order is sent completely, and state 4 can jump to 5, PMI and drive two output relays to high-order.And due to the arbitrary relay of designing requirement for PMI time high-order can not accept the initial pre-reset order of ATS, then state 9 can jump to 8, and logic state is 1,5,6,8.At PMI output relay to after high-order countdown in 7 seconds terminates, state 5 can jump to 4 automatically, and state 8 also can jump to 9 again, prepares to accept the order of the long-range meter shaft pre-reset of ATS next time.Now logic state returns 1,4,6,9.
2, PMI detects one of them relay fault, then state can jump to 7 by 6, and according to design, have fault that PMI will be caused not accept the order of ATS pre-reset, then state 9 can jump to 8, and logic state is 1,4,7,8.If now ATS sends initial pre-reset order to PMI, 2 can not be jumped to from 1 because PMI now can not accept ATS order.
3, PMI detects relay failure recovery, and two relay status are all low level, then state can get back to 6 by 7 redirects, and state 8 can jump to 9, and logic state is 1,4,6,9, if now ATS sends the order of long-range meter shaft pre-reset, and can refer step 1.
Refer to Fig. 5, the long-range note axle pre-reset method based on above-mentioned long-range note axle pre-reset system of the present invention, comprises the following steps:
ATS server receives the pre-reset instruction that operator sends, or, ATS server is according to the output state of two of PMI back production relays, when judging two equal troubles free of relay and be all in low-end trim, export the order of long-range meter shaft pre-reset to PMI, this long-range meter shaft pre-reset order is a security command needing secondary-confirmation.First ATS server can send the order of an initial remote meter shaft pre-reset, and PMI can be reported to ATS server (return and acknowledge receipt of instruction) after receiving 10 seconds.ATS server sent again and once confirms the order of long-range meter shaft pre-reset in 20 seconds, such PMI just really can accept this order, drive two output relays and guard relay high-end trim 7 seconds, after countdown in 7 seconds terminates, two output relays are set to low-end trim by PMI immediately.The definition of 7 seconds considers: the communication time delay of ATS and PLC 2 seconds+PLC export the surplus of 3 seconds+2 seconds.
The order of PMI output enable, drive two relays to keep high-end trim, back production information is also returned to ATS server by the status information that back production is two;
After ATS server is all positioned at high-end trim according to back production validation of information two relays, send the order of long-range note axle pre-reset to PLC; The output of PLC control ACE 3 seconds, the wheel counting apparatus of disturbed section all resets by enough ACE.After train or simulating wheel this disturbed ACB swept also recover, ATS server shows this ACB state normal.
To sum up, the present invention is independently, does not affect other interlocks, and can the demand different according to each client of every bar line configure from interlocking table.For PMI software, in interlocking table " ACB_RPEPRESET_RELAYS " this when being classified as sky, just do not realize this function, as long as and in interlocking table, define the name of these two output relays, just can realize this function.Thus realize replacing manual operation button to carry out enable PLC by PMI.And ACE rack and interface not any change, service personnel still can use key switch to realize meter shaft pre-reset.
