Description

The temporary speed-limiting method of PMI interlocking system under a kind of some formula ATP pattern

Technical field

The present invention relates to field of urban rail.

Background technology

When train passes through the land of accident, natural disaster or hot work in progress (tunneling operation etc.), or the track region caused due to platform emergency stop push button activation etc. closes, in order to ensure train operating safety, train running speed will lower than the safety speed value-temporary speed limitation value set in advance. If train has exceeded temporary speed limitation value by temporary speed limitation section operate speed, it is possible to entail dangers to driving safety, even may there is the great driving accidents such as train derailing, overturning or train colliding time serious, jeopardize passenger's life, cause equipment and property damage.

At present, signalling system is under communication-based train control CBTC (CommunicationBasedTrainControl) pattern, it is possible to realize temporary speed limitation is applied to the controlled train operated in CBTC control district. Under CBTC pattern, mobile authorization unit MAU (MovementAuthorityUnit) receives from ATS (AutomaticTrainSupervision, train automatic monitoring subsystem) route request, then along the route of ATS request, mobile authorization restriction LMA (LimitofMovementAuthority) is calculated by train of the POS INT of train report. LMA will be restricted to the nearest obstacle on ATS route, if not having obstacle, will be restricted to ultimate range, it is ensured that is the reserved necessary track of train and equipment. If the ATS route of train and track switch are handed over folded, MAU can ask the PMICBTC route by interlocking limit; As PMI (PostedeManoeuvreInformatis é (ComputerBasedInterlockingsystem), computer interlock subsystem) report that the CBTC route that MAU requires is authorized after, MAU just extends LMA by this route region. When MAU determine controlled train mobile authorization can by teleseme time, MAU will send bypass teleseme order to PMI, by PMI arrange teleseme allow display.MAU knows the accurate position of all trains in its control district, it is determined that the LMA of extension train when can be safe, thus the teleseme in bypass LMA. The mobile inaccessible principle of application under signalling system CBTC pattern, train runs (train runs ATO (AutomaticTrainOperation) pattern, artificial train automatic protection ATPM (AutomaticTrainProtectionManual) pattern automatically) under master mode and sets up its unoperated position with LMA. Under backup mode, MAU does not operate, ATS sends route request to PMI, PMI sets up standby route and open standby route start signal machine based on fixed blocking principle, train is with a formula ATP and IATP (IntermittentAutomaticTrainProtection, point formula train automatic protection) pattern, and the standby route and the display of trackside teleseme according to PMI foundation travels.

IATP pattern, this pattern be system cloud gray model when backup mode, manually drive train by driver but system guarantee train ATP point formula protection. In such a mode, Vehicle Controller VOBC (VehicleOnboardController) only allows train upwards to run authorized party, and VOBC dallies for train provides/skids and detects, overspeed protection, slipping protection, the red light that advances rashly is supervised, the ATP functions such as unplanned enabling supervision. VOBC only forces to implement B beacon detection function in such a mode, and B beacon can indicate front signal machine state, to allow VOBC realize and supervise driver and advance in accordance with braking curve. VOBC calculates the permission velocity curve corresponding to train mandate speed, and corresponding train mandate speed is displayed in train operation display screen TOD (TrainOperationDisplay). Driver drives train according to the speed supervision instruction of display on the display of trackside teleseme and TOD, if train speed exceedes Speed limit curve, it is provided that sound alarm; If train speed exceedes Speed limit curve and hypervelocity tolerance limit, in offer sound alarm simultaneously, VOBC will apply snub. Once train snub is stopped, first need driver to be pressed against the snub reset button of wheel house manually to discharge snub, train just can be made to dispatch a car.

Under signalling system backup mode, IATP pattern train runs in accordance with the display of trackside teleseme. In order to ensure train with the speed of safety by temporary speed limitation section, a distance, speed limit section both sides need to arrange temporary speed limitation board, and prompting driver notices that front arrives temporary speed limitation section, need to run by the speed pointed out lower than temporary speed limitation board. But in real work, there is urgent temporary speed limitation that temporary speed limitation board is set if desired along the line not flexible, and if the speed of a motor vehicle is too fast or driver fatigue, miss or do not have the speed limitation board in Timeliness coverage speed limit section front, train is it is possible to hypervelocity enters speed limit section, thus causes driving accident.

Therefore, for ensureing that train passes through temporary speed limitation section with IATP mode safety, temporary speed limitation is included signalling system backup mode function in very necessary.

Summary of the invention

It is an object of the invention to provide the temporary speed-limiting method of PMI interlocking system under a kind of some formula ATP pattern, realize PMI for IATP pattern train performs to be arranged in track region temporary speed limitation TSR (TemporarySpeedRestriction) under backup mode, and the teleseme in these temporary speed limitation regions of protection is carried out interlocking association.

The technical scheme realizing above-mentioned purpose is:

A temporary speed-limiting method for PMI interlocking system under some formula ATP pattern, comprising:

When PMI starts, the TSR in all track regions of initial setting up is ' setting ' state;

After PMI is switched to backup mode, then by ATS be sent to PMI safely order remove without the need to arrange TSR;

The start signal machine TSR of standby route that authorizes in the track region after TSR is arranged is activated, start signal machine display red light; When the TSR in the unblock of standby route or standby route removes, then teleseme TSR is un-activation state;

If teleseme TSR activates, then teleseme display red light, open permission signal, before train operator is parked in red signal machine, communicate with ATS operator, after being confirmed to be the teleseme red light caused due to temporary speed limitation, ATS operator order PMI temporarily open teleseme allow display, and inform that driver passes through teleseme with the speed lower than temporary speed limitation value;

When the default condition that can accept ATS removing order meets, the confirmation teleseme TSR that PMI accepts ATS removes safety order, and teleseme TSR removing state is " removing " state, and starts the countdown of an X time;

When default teleseme TSR from ' removing state ' turn into ' not removing state ' condition meet time, teleseme TSR remove state turn into " removing " state.

Under above-mentioned some formula ATP pattern in the temporary speed-limiting method of PMI interlocking system, the described condition that can accept ATS removing order comprises:

Open other conditions allowed of command signal machine except teleseme TSR state, teleseme TSR removing state, teleseme allow locking states are all satisfied;

Teleseme TSR state is for activating;

State removed by teleseme is unconfirmed;

The TSR of teleseme takies close to section.

Under above-mentioned some formula ATP pattern in the temporary speed-limiting method of PMI interlocking system, described teleseme TSR from ' removing state ' turn into ' not removing state ' condition be following condition one of any:

X time countdown terminates;

ATS sends " cancelling teleseme TSR to remove " order;

Command signal machine except teleseme TSR state, teleseme TSR removing state is cancelled the open either condition allowed and is met;

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

Temporary speed limitation is that TSR order is two portions data: track region ID and speed limit by ATS operator to the order of the temporary decrease maximum permission speed that some section on circuit (definition different track regions in a database) carries out.ATS can be applied by safety order or cancel temporary speed limitation, and speed limit can increase from 15km/h, is that the mode of stepping is increased to top speed taking 5km/h. Concerning ATS operator, temporary speed limitation function is divided into two types: system temporary speed limitation and code temporary speed limitation. System temporary speed limitation, namely the track region being provided with TSR is provided speed limit protection by system. And the code temporary speed limitation temporary speed-limiting method of PMI interlocking system (that is: under the some formula ATP pattern of the present invention), it is by the speed limit of rules and procedures for operation synchronization implementation by train operator and ATS operator. Code temporary speed limitation function provides the protection of trackside signal, and driver drives train according to the display of trackside teleseme.

As shown in Figure 1, although the setting steps of two kinds of temporary speed limitations is identical, but there is obviously difference in systems in which: when control district is CBTC pattern, TSR order is only sent to MAU by ATS, and MAU can by TSR transferring order to PMI; When Er Dangkong district is backup mode, TSR order is only sent to PMI by ATS, and TSR status report to MAU, but is not comprised restriction speed information by PMI, and itself and the teleseme protecting these temporary speed limitation regions can be carried out interlocking and associate by PMI.

System temporary speed limitation is applied to the controlled train operated in CBTC control district. MAU is after receiving the TSR of ATS by safe command set, it will be resolved and verify, then the TSR list after determining is issued the controlled train VOBC in control district, and inform that whether PMI is reset TSR by MAU under CBTC pattern and the track region temporary speed limitation ID of confirmation forwards to PMI[this operates to be avoided ATS operator to re-start TSR order after switching operation mode, TSR order need to be kept by PMI: when controlling district and be switched to backup mode from CBTC pattern, all TSR orders that PMI keeps will be performed immediately, and by status report to ATS; When being switched to CBTC pattern from backup mode, all TSR orders that PMI keeps can be forwarded to MAU, MAU acknowledged after will perform the TSR order that receives from PMI immediately, and by status report to ATS. Not comprising speed limiting information owing to coming from the order of PMI, MAU will arrange minimum speed limit (15km/h), and the speed limit in these track regions need to be modified by ATS operator. ], MAU keeps up-to-date temporary speed limitation order is applied to the track region specified, and namely temporary speed limitation can be modified to higher or lower numerical value. When LMA and the TSR region of a controlled train of row is overlapping, VOBC continues the ATP speed limit that calculating is authorized and the ATP speed limit forcing enforcement new based on the speed limit of relevant range, and hypervelocity can cause applying snub and protect. The realization of system temporary speed limitation does not show based on trackside teleseme. For the controlled train under CBTC pattern, TSR will be applied in whole train length, and guarantee train is entered TSR region with the speed of TSR by VOBC, and keeps this speed until detecting that last vehicle of train goes out TSR region clearly.

Code temporary speed limitation is applied to the non-controlled train (IATP or restriction artificial mode RM (RestrictedManual)) operating under backup mode. After arranging TSR, PMI can order the teleseme being associated for forbidding display. Train operator drives train stops before every frame inhibit signal machine, and communicate with ATS operator, thus know the temporary speed limitation information by front section, owing to can there is multiple track region in a meter shaft section, if there is different speed limits in these regions, only minimum speed limit will be used. ATS operator should confirm temporary speed limitation with train operator, and inform driver only just being allowed display by ATS operation (sending safety order to PMI) interim open teleseme close to section during train occupation, and after the open teleseme of ATS operator allows, have the countdown of 60 seconds.If countdown in 60 seconds terminates or train goes out clearly close to section, teleseme will be recovered as forbidding display by order.

From PMI interlock logic, TSR can be arranged by ATS at backup mode or arrange by MAU under CBTC pattern, but can only at backup mode when being applied to teleseme interlock. Such as, under CBTC pattern, after the TSR in certain track region is arranged, CBTC route start signal machine can not be had impact by this TSR, under backup mode, after the TSR in certain track region is arranged, activate the TSR of the standby route start signal machine being associated, close to information such as section seizure conditions, PMI is again according to judging that can this teleseme TSR be cancelled once, therefore relevant to TSR function can be divided into: track region TSR arranges/removes; Teleseme TSR activation/un-activation; Teleseme TSR remove/does not remove.

Track region TSR arranges/removes:

Based on security design principle, PMI arranges the TSR in all track regions after start-up. After PMI is switched to backup mode, then by ATS be sent to PMI safely order remove without the need to arrange TSR. After PMI is switched to CBTC pattern, the TSR without the need to arranging is removed in the combination of two orders (the TSR state of following table 1 arranges/remove truth table) that PMI sends according to MAU:

Table 1

As shown in Table 1, PMI after only receiving the combination order that the TSR in certain track region is reset by MAU and settings/TSR resets and removes just can the TSR in arrange accordingly/removings track region, order if MAU does not send to reset, PMI is by the TSR state before maintenance.

Refer to Fig. 2, represent that track region TSR arranges/remove the inner logical design of PMI of function with state machine diagram. In 0 state when starting at the beginning of PMI, without input and output, inner variable is not had to change yet. For security consideration, PMI starts rear logic state 1,9,3,6,11, namely gives tacit consent to startup state for arrange/to remove TSR order without ATS, and TSR can not arrange/can not remove, and TSR is arranging state. If now PMI is switched to CBTC pattern, the TSR receiving MAU resets and removes order, then jump to 12, TSR by state 11 and be eliminated, and now logic state is 1,9,3,6,12; If the TSR now receiving MAU resets and setting command, then jumping back to 11, TSR by state 12 and be set up, now logic state returns to 1,9,3,6,11. If PMI is switched to backup mode, owing to TSR is arranged, state 1 can jump to 2, and namely TSR can remove, and logic state is 2,9,3,6,11; Owing to TSR can remove, after assigning, by ATS, the safety order (state 3,4,5 is to control safe order process) removing TSR, state 11 jumps to 12,2 and jumps to 1,9 and jump to 10, and logic state is 1,10,3,6,12; Owing to TSR can be arranged, assign the safety order (state 6,7,8 is to control safe order process) arranging TSR by ATS after, state 12 jumps to 11,1 and jumps to 2,10 and jump to 9, and logic state is 2,9,3,6,11.

Teleseme TSR activation/un-activation: when PMI is under backup mode, after the TSR in certain one or more track region is arranged, is activated through the start signal machine TSR of standby route that authorizes in this track region, start signal machine display red light. When the TSR in the unblock of standby route or standby route removes, then teleseme TSR is un-activation state. Under CBTC pattern, this function is performed by MAU, is transparent concerning PMI.

Refer to Fig. 3, carry out the inner logical design of PMI of expression signal machine TSR activation/un-activation function with state machine diagram. In 0 state when starting at the beginning of PMI, without input and output, inner variable is not had to change yet. In 4 states after PMI startup, namely teleseme TSR state is un-activation, if arbitrary track region of any standby route process now by start signal machine of this teleseme is provided with TSR, and standby route is authorized, then jumping to 5 by state 4, teleseme TSR activates; If the track region of now all relevant standby routes unblock or all processes all removes TSR, then state 5 redirect returns to 4, teleseme TSR un-activation.

Teleseme TSR remove/does not remove:

When PMI is under backup mode, if teleseme TSR activates, then teleseme display red light, permission signal can not be opened, before train operator to be parked in red signal machine, and communicate with ATS operator, ATS operator and train operator acknowledged be the teleseme red light caused due to temporary speed limitation after, ATS operator can order PMI open teleseme permission display temporarily, and informs that driver passes through teleseme with the speed lower than temporary speed limitation value.

When the following default condition that can accept ATS removing order all meets, the confirmation teleseme TSR that PMI accepts ATS removes safety order, and teleseme TSR removing state is " removing " state, and starts the countdown of 60 seconds:

Open other conditions allowed of command signal machine except teleseme TSR state, teleseme TSR removing state, teleseme allow locking states are all satisfied;

Teleseme TSR state is for activating;

State removed by teleseme is unconfirmed;

The TSR of teleseme takies close to section.

When following default either signal machine TSR from ' removing state ' turn into ' not removing state ' condition meet, teleseme TSR remove state turn into " removing " state:

Countdown in 60 seconds terminates;

ATS sends " cancelling teleseme TSR to remove " order;

Command signal machine except teleseme TSR state, teleseme TSR removing state is cancelled the open either condition allowed and is met;

The TSR of teleseme is close to clearing of section;

Other TSRs relevant to teleseme are set up.

Owing to this function and teleseme TSR activation/un-activation function are all teleseme function, represent so these two functions share a state machine diagram, and no longer repeat the redirect of state 4,5. See Fig. 3:

In 0 state when starting at the beginning of PMI, without input and output, inner variable is not had to change yet. In 1,6,8 states after PMI startup, namely not having the confirmation teleseme TSR of ATS to remove order, teleseme TSR can not remove and not remove state. If arbitrary track region of any standby route process now by start signal machine of this teleseme is provided with TSR, and above-mentioned PMI accept ATS confirmation teleseme TSR remove safety order in each condition meet, then state 8 jumps to 9, and logic state is 1,6,9; After assigning, by ATS, the safety order (state 1,2,3 is to control safe order process) that acknowledgement signal machine TSR removes order, state 6 jumps to 7, and state 9 jumps to 8, and logic state is 1,7,8; If now above-mentioned teleseme TSR remove state turn into the either condition in " unconfirmed " state meet, as countdown in 60 seconds terminates, state 7 jumps to 6, and state 8 jumps to 9, and logic state is 1,6,9.

When signalling system normal operation, ATS, MAU, PMI realize complete TSR function.

Referring to Fig. 4, sight a, control district is in CBTC pattern. ATS operator sends safety order from ATS and arranges TSR to MAU, comprises ID and the speed limit of TSR, and MAU resolves after accepting order and verifies TSR order, is reported to the state of ATSTSR and upgrades TSR list. When controlling district and be switched to backup mode from CBTC pattern, all TSR orders that PMI keeps will be performed immediately, and by status report to ATS.

Referring to Fig. 5, sight b, control district is at backup mode. ATS operator sends safety order from ATS and arranges TSR to PMI, and order here only includes the ID of TSR, does not comprise speed limit, and PMI verifies TSR order after accepting order, and is reported to ATSTSR and arranges state. When being switched to CBTC pattern from backup mode, all TSR orders that PMI keeps can be forwarded to MAU, MAU acknowledged after perform the TSR order that receives from PMI immediately, and by status report to ATS. Not comprising speed limiting information owing to coming from the order of PMI, MAU will arrange minimum speed limit (15km/h), and the speed limit in these track regions need to be modified by ATS operator.

Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to the category of the present invention, should be limited by each claim.
