Description

TECHNICAL FIELD

[0001] The present application relates to the field of railway signal, in particular to a control and protection method and system for a transition turnout connecting different types of lines. BACKGROUND

[0002] For the transition turnout, the current implementation scheme generally adopts the mode complying with the provisions of Chapter 4.2 of the Railway Industry Standard "General Principles of Centralized Interlocking Combination Circuit" (TB / T 2307-2017). The mode is controlled by one interlocking device, which normally locks the transition turnout at a position separating two yards. When a turn-around operation or maintenance of the turnout is needed, the two yard dispatchers communicate by telephone and press the agreed turnout button to release the lock of the turnout. After the turnout is manually operated to the reverse position, the route is handled. Since the current implementation scheme requires manual operation of the turnout, the dispatching system cannot automatically handle the turn-around route. When the turn-around operation between the two yards is small and the efficiency requirement for train turn-around is low, this implementation scheme can be applicable. However, the city (suburban) railway adopts a public transportation operation mode with short train running intervals. If the transition turnout is manually controlled and the turn-around route is manually handled, the turn-around route handling efficiency will be greatly reduced, which cannot meet the demand of the public transportation operation of the city (suburban) railway and becomes a bottleneck for train operation efficiency.

[0003] The statements herein only provide background technology related to the present application and do not necessarily constitute the prior art. SUMMARY

[0004] The purpose of the present application is to provide a control and protection method and system for a transition turnout connecting different types of lines, which can meet the requirement of automatic triggering of the turn-around route, improve the efficiency of train turn-around between different types of lines, ensure the public transportation operation interval, simplify the maintenance operation process of the transition turnout, and ensure the safe operation of trains in the transition turnout area.

[0005] In order to achieve the above purpose, the present application provides a control and protection method for a transition turnout connecting different types of lines. The interlocking devices of different types simultaneously receive operation commands from the dispatching centralized system, and perform control and protection on the transition turnout or the route passing through the transition turnout according to different operation commands.

[0006] The control and protection method comprises: the interlocking devices of different types separately control the transition turnouts located on different types of lines, and exchange information and instructions between the interlocking devices of different types to cooperatively complete the control and protection of the route passing through the transition turnout.

[0007] Among them, the first type of line is referred to as the local line, and the interlocking device of the first type is referred to as the local interlocking device. The local interlocking device separately controls the transition turnout located on the local line.

[0008] The second type of line is called the opposite line, the interlocking equipment of the second type is called the opposite interlocking equipment, and the opposite interlocking equipment controls the joint switch on the opposite line independently;

[0009] The information and instructions are exchanged between the home interlocking equipment and the opposite interlocking equipment.

[0010] If the operation command received by the home interlocking equipment and the opposite interlocking equipment is the routine maintenance of the joint switch, the home interlocking equipment controls the joint switch on the home line independently, and the opposite interlocking equipment controls the joint switch on the opposite line independently.

[0011] The method for controlling the joint switch independently comprises the following steps:

[0012] If the joint switch on the home line or the opposite line is not locked, the home interlocking equipment or the opposite interlocking equipment outputs the joint switch action command to the joint switch on the home line or the opposite line.

[0013] When the joint switch on the home line or the opposite line is turned to the position, the home interlocking equipment or the opposite interlocking equipment stops outputting the joint switch action command after collecting the corresponding position indication of the joint switch.

[0014] If the operation command received by the home interlocking equipment and the opposite interlocking equipment is the route positioning through the joint switch on the home line, the home interlocking equipment and the opposite interlocking equipment control the route jointly, the opposite interlocking equipment / the home interlocking equipment controls the joint switch on the opposite line / the home line to be locked in the position, and the opposite interlocking equipment / the home interlocking equipment can release the lock of the joint switch on the opposite line / the home line only after the home interlocking equipment / the opposite interlocking equipment requests to release the lock of the joint switch on the opposite line / the home line.

[0015] The method for controlling the route jointly comprises the following steps:

[0016] The home interlocking equipment sends a command to the opposite interlocking equipment to request the joint switch on the home line to be positioned in the position of the associated switch, and the associated switch is the joint switch on the opposite line.

[0017] The opposite interlocking equipment positions the associated switch in the position and feeds back the position of the associated switch to the home interlocking equipment.

[0018] The home interlocking equipment locks the route and sends a command to the opposite interlocking equipment to lock the associated switch.

[0019] The opposite interlocking equipment locks the associated switch in the position and feeds back the lock state of the associated switch to the home interlocking equipment.

[0020] The home interlocking device opens the signal, and the route is unlocked along with the train operation;

[0021] The home interlocking device sends a command to the other interlocking device to unlock the associated switch;

[0022] The other interlocking device releases the locking of the associated switch.

[0023] The operation command received by the home interlocking device and the other interlocking device is to handle a crossover route, the crossover route includes a front route and a rear route, the front route includes a connecting switch located on the other line, the front route is controlled by the other interlocking device, and the rear route includes a connecting switch located on the home line, the rear route is controlled by the home interlocking device;

[0024] Then the home interlocking device and the other interlocking device cooperatively control and protect the crossover route, the home interlocking device controls the rear route to open the signal, and then the other interlocking device controls the front route to open the signal, and then the other interlocking device controls the front route to unlock, and then the home interlocking device controls the rear route to unlock.

[0025] The method for cooperatively controlling and protecting the crossover route includes:

[0026] After the home interlocking device receives a rear route handling command from the dispatching centralized system, the other connecting switch located on the home line and constituting a crossover with the connecting switch through which the rear route passes is moved to a position by the home interlocking device;

[0027] After the home interlocking device locks the rear route and the other connecting switch located on the home line and constituting a crossover with the connecting switch through which the rear route passes, the home interlocking device controls the rear route to open the signal, and then sends a rear route opening signal to the other interlocking device;

[0028] After the other interlocking device receives a front route handling command from the dispatching centralized system, if the rear route signal is open, the other interlocking device locks the front route and the other connecting switch located on the other line and constituting a crossover with the connecting switch through which the front route passes, and then controls the front route to open the signal;

[0029] The other interlocking device controls the front route to be unlocked along with the train operation, the other interlocking device releases the locking of the other connecting switch located on the other line and constituting a crossover with the connecting switch through which the front route passes, and then feeds back the unlocking state of the front route to the home interlocking device;

[0030] After the front route is unlocked, the home interlocking device controls the rear route to be unlocked along with the train operation.

[0031] The application also provides a control and protection system for a junction turnout connecting different mode lines, which is used for realizing the control and protection method for the junction turnout connecting different mode lines, and comprises a dispatching centralized system and a plurality of different mode interlocking devices.

[0032] The dispatching centralized system is used for sending operation commands to the different mode interlocking devices.

[0033] The different mode interlocking devices respectively and individually control the junction turnouts located on different mode lines, and the information and instructions are interacted between the different mode interlocking devices.

[0034] The application has the following beneficial effects:

[0035] The application adopts the different mode interlocking devices for respectively and individually controlling the junction turnouts located on different mode lines. During daily maintenance of the junction turnouts, the on-duty staff can individually control the turnouts of the line, and does not need to request the on-duty staff of the adjacent different mode line for complicated approval of turnout operation, so that the turnout operation process of the junction turnout is simplified, the maintenance time is saved, and the workload of the on-duty staff is reduced.

[0036] The application uses the different mode interlocking devices for cooperatively controlling the junction turnouts and the routes in the junction turnout area on different mode lines. The different mode interlocking devices are cooperated with each other to complete the automatic operation, locking and unlocking of the junction turnouts, and do not need the on-duty staff of the adjacent different mode line to manually handle the approval of the turnout operation. The manual participation process is cancelled, the automatic handling of the transfer route is realized, the efficiency of the double mode train cross-line operation is improved, and the public transportation operation of the city (suburban) railway is ensured.

[0044] The present application provides a control and protection method for connecting turnouts connecting different system lines, which changes the control and protection method for connecting turnouts from being uniformly controlled by an interlocking device of one system to being controlled by interlocking devices of different systems respectively.

[0045] In an embodiment of the present application, as shown in Figure 1 , a CTCS system line and a CBTC system line are connected through connecting turnouts, wherein the first turnout SW1 and the second turnout SW2 are located on the CTCS system line, the third turnout SW3 and the fourth turnout SW4 are located on the CBTC system line, the routes Route1 and Route2 are located on the CTCS system line, the routes Route3 and Route4 are located on the CBTC system line, the first turnout SW1 and the fourth turnout SW4 form the first crossover (i.e. the first group of connecting turnouts), the second turnout SW2 and the third turnout SW3 form the second crossover (i.e. the second group of connecting turnouts), and the first group of connecting turnouts and the second group of connecting turnouts form a cross-over. In this embodiment, the first turnout SW1, the second turnout SW2, the third turnout SW3 and the fourth turnout SW4 are all connecting turnouts. The jurisdiction boundary between the CTCS system interlocking device and the CBTC system interlocking device is located at the signal machine separating the connecting turnouts, as shown in Figure 1As shown, signals S5 and S6 at the interlocking boundary are managed by the CBTC interlocking equipment, while signals S7 and S8 at the interlocking boundary are managed by the CTCS interlocking equipment. According to the present invention, a control and protection method for connecting switches connecting lines of different standards is provided. If the first switch SW1 and the second switch SW2 are located on a CTCS line, the CTCS interlocking equipment will independently control the first switch SW1 and the second switch SW2. If the third switch SW3 and the fourth switch SW4 are located on a CBTC line, the CBTC interlocking equipment will independently control the third switch SW3 and the fourth switch SW4. After the connecting turnouts are controlled by the CTCS interlocking equipment and the CBTC interlocking equipment respectively, in order to ensure the safe operation of trains in the connecting turnout area, the CTCS interlocking equipment and the CBTC interlocking equipment communicate and exchange the connecting turnout action commands, connecting turnout locking commands, connecting turnout unlocking commands, connecting turnout positioning status, connecting turnout locking status, connecting turnout unlocking status, transfer route signal open status, and transfer route unlocking status information, and work together to complete the route arrangement and safety protection in the connecting turnout area.

[0046] In this embodiment, if Figure 2 As shown, the control and protection method for connecting turnouts connecting lines of different standards specifically includes the following steps:

[0047] Step S1, interlocking devices of different types simultaneously receive operation commands from the centralized dispatching system, and execute control and protection methods on the connecting switches or the routes passing through the connecting switches according to different operation commands.

[0048] If the operation command is to perform routine maintenance of the connecting turnout, proceed to step S1;

[0049] If the operation command is to process the route through the connecting turnout positioning, then proceed to step S2;

[0050] If the operation command is to process a line change route, proceed to step S3.

[0051] Step S2: During routine maintenance of the connecting turnouts, the actions of the connecting turnouts on the own line are individually controlled by the interlocking equipment of the own line.

[0052] like Figure 3 As shown, the method for individually controlling the connecting turnout specifically includes the following steps:

[0053] Step S2.1: The local line interlocking device determines whether it has received a separate switch operation command. If so, it proceeds to step S2.2; otherwise, it returns to step S2.1.

[0054] Step S2.2, the line interlocking device of the local line judges whether the connecting turnout on the local line is not locked, if yes, it goes to step S2.3, otherwise, it returns to step S2.2;

[0055] Step S2.3, the line interlocking device of the local line outputs a connecting turnout action command to the connecting turnout on the local line, and the connecting turnout on the local line starts to rotate;

[0056] Step S2.4, the connecting turnout rotates to the position, and the line interlocking device of the local line stops outputting the turnout action command after collecting the corresponding position indication of the connecting turnout.

[0057] When the connecting turnout is maintained daily, the operator can operate the connecting turnout on the local line through the interlocking device of the local line, without the cumbersome process of requesting and agreeing with the operator of the adjacent line of different types, which simplifies the maintenance process of the connecting turnout and saves maintenance time.

[0058] Step S3, when the route passing through the connecting turnout is positioned, the interlocking devices of different types are used to cooperatively control the route of the connecting turnout on the lines of different types, the interlocking devices of different types communicate with each other, the interlocking device of the local line is the interlocking device of the first type, and the interlocking device of the local line controls the connecting turnout on the local line. The interlocking device of the other party is the interlocking device of the second type, and the interlocking device of the other party controls the connecting turnout on the line of the other party.

[0059] When the route passing through the connecting turnout is positioned, the interlocking device of the local line sends a command to the interlocking device of the other party to position the associated turnout of the connecting turnout on the local line to the position, the associated turnout is the connecting turnout on the line of the other party; the interlocking device of the other party positions the associated turnout of the connecting turnout to the position and feeds back the positioning state to the interlocking device of the local line; the interlocking device of the local line locks the route and sends a command to the interlocking device of the other party to lock the associated turnout of the connecting turnout; the interlocking device of the other party locks the associated turnout of the connecting turnout to the position and feeds back the locking state to the interlocking device of the local line; the interlocking device of the local line opens the signal, and the local line and the line of the other party are absolutely separated by the connecting turnout locked to the position, which avoids the risk of side collision of the train on the local line with the train on the line of the other party after the train on the line of the other party advances the signal, and ensures the safety of train operation.

[0060] As shown in Figure 4 the connecting turnout control protection method when the route passing through the connecting turnout is positioned specifically includes the following steps:

[0061] Step S3.1, the interlocking device of the local line judges whether a route passing through the connecting turnout is positioned, if yes, it goes to step S3.2, otherwise, it returns to step S3.1;

[0062] Step S3.2, the interlocking device of the first party sends a command of setting the associated switch of the transition switch to the interlocking device of the second party;

[0063] Step S3.3, the interlocking device of the second party judges whether the associated switch of the transition switch is not locked, if yes, the process goes to step S3.4, otherwise, the process returns to step S3.3;

[0064] Step S3.4, the interlocking device of the second party sets the associated switch of the transition switch to the position and feeds back the position of the associated switch to the interlocking device of the first party;

[0065] Step S3.5, the interlocking device of the first party locks the route and sends a command of locking the associated switch of the transition switch to the interlocking device of the second party;

[0066] Step S3.6, the interlocking device of the second party locks the associated switch of the transition switch and feeds back the lock state of the associated switch to the interlocking device of the first party;

[0067] Step S3.7, the interlocking device of the first party opens the signal;

[0068] Step S3.8, the route is unlocked with the train running;

[0069] Step S3.9, the interlocking device of the first party sends a command of unlocking the associated switch of the transition switch to the interlocking device of the second party;

[0070] Step S3.10, the interlocking device of the second party unlocks the associated switch of the transition switch after receiving the command of unlocking the associated switch of the transition switch from the interlocking device of the first party.

[0071] In the embodiment, as shown in FIG. 1, the control and protection process of the route Route3 positioned by the third transition switch SW3 and the fourth transition switch SW4 is taken as an example for illustration: Figure 1

[0072] 1. The route Route3 is managed by the CBTC interlocking device;

[0073] 2. After the CBTC interlocking device handles the route Route3, the CBTC interlocking device sends a command of requesting the first switch SW1 and the second switch SW2 to be set to the position to the CTCS interlocking device;

[0074] 3. After the CTCS interlocking device receives the command of requesting the first switch SW1 and the second switch SW2 to be set to the position, the CTCS interlocking device checks whether the first switch SW1 and the second switch SW2 are locked, and if not, outputs the command of requesting the first switch SW1 and the second switch SW2 to be set to the position;

[0075] ​4. After the first switch SW1 and the second switch SW2 are set to the position, the CTCS mode interlocking device sends the switch position information to the CBTC mode interlocking device, and the CBTC mode interlocking device locks the route Route3 after receiving the switch position information of the first switch SW1 and the second switch SW2.

[0076] 5. After the route Route3 is locked, the CBTC mode interlocking device sends the locking command of the first switch SW1 and the second switch SW2 to the CTCS interlocking device.

[0077] 6. After receiving the locking command of the first switch SW1 and the second switch SW2, the CTCS mode interlocking device checks whether there is no action command of the first switch SW1 and the second switch SW2, and locks the first switch SW1 and the second switch SW2, and sends the locking state of the first switch SW1 and the second switch SW2 to the CBTC mode interlocking device.

[0078] 7. After receiving the locking state of the first switch SW1 and the second switch SW2, the CBTC mode interlocking device opens the signal S1.

[0079] 8. After the train clears the route Route3, the CBTC interlocking device unlocks the route Route3, and sends the unlocking command of the first switch SW1 and the second switch SW2 to the CTCS mode interlocking device after the route Route3 is unlocked.

[0080] 9. After receiving the unlocking command of the first switch SW1 and the second switch SW2, the CTCS mode interlocking device unlocks the first switch SW1 and the second switch SW2.

[0081] In step S4, the interlocking devices of different modes are used to cooperatively implement the safety protection of the route in the switch region, and the interlocking devices of different modes communicate with each other, the interlocking device of the first mode is the local interlocking device, and the local interlocking device controls the switch on the local line; the interlocking device of the second mode is the opposite interlocking device, and the opposite interlocking device controls the switch on the opposite line.

[0082] When the transfer route is implemented, the transfer route includes a front route and a rear route; the front route includes a starting signal, a non-switch section and a switch on the local line, and a non-switch section and a terminal signal on the crossover line, and the front route is controlled by the opposite interlocking device; the rear route includes a starting signal and a non-switch section on the crossover line, and a switch, a non-switch section and a terminal signal on the opposite line, and the rear route is controlled by the local interlocking device; and the switches on the transfer route are all in the reverse position. Figure 1As shown, in an embodiment of the present application, the route for switching from the CBTC mode line to the CTCS mode line includes route Route 5 and route Route 6. When the train performs the switching operation, the route first passed is defined as the front section route Route 5, and the route passed later is defined as the rear section route Route 6. The front section route is controlled by the CBTC interlocking system, and the rear section route is controlled by the CTCS interlocking system. The interlocking system controlling the rear section route is referred to as the local interlocking, and the interlocking system controlling the front section route is referred to as the opposite interlocking.

[0083] The local interlocking device and the opposite interlocking device move another set of connected turnouts constituting the cross-over to the position and lock the connected turnouts on the switching route. After the rear section route is opened, the front section route can be opened. After the front section route is unlocked, the rear section route can be unlocked. The signal opening processing scheme of the switching route avoids the risk of the train rushing into the rear section route, and the route unlocking scheme avoids the risk of derailment and falling off the track caused by the train rushing into the already unlocked rear section route, thereby ensuring the safety of the double-mode train switching.

[0084] As shown, the control and protection method of the connected turnouts when the switching route is handled includes the following steps: Figure 5

[0085] Step S4.1, the local interlocking device judges whether a rear section route handling command from the dispatching centralized system is received. If yes, go to step S4.2, otherwise return to step S4.1.

[0086] Step S4.2, the local interlocking device moves another connected turnout constituting the cross-over to the position, which is another connected turnout governed by the local interlocking device and passes through the rear section route.

[0087] Step S4.3, after the local interlocking device locks the rear section route and locks another connected turnout constituting the cross-over, which is another connected turnout governed by the local interlocking device and passes through the rear section route, the local interlocking device controls the rear section route to open the signal, and then sends the rear section route opening signal to the opposite interlocking device.

[0088] Step S4.4, the opposite interlocking device judges whether a front section route handling command from the dispatching centralized system is received. If yes, go to step S4.5, otherwise return to step S4.4.

[0089] Step S4.5, the opposite interlocking device judges whether the rear section route signal is opened. If yes, go to step S4.6, otherwise return to step S4.5.

[0090] Step S4.6, after the opposite interlocking device locks the front section route and locks another connected turnout constituting the cross-over, which is another connected turnout governed by the opposite interlocking device and passes through the front section route, the opposite interlocking device controls the front section route to open the signal.

[0091] ​Step S4.7, the opposite interlocking device controls the front section route to be unlocked with the train operation, the opposite interlocking device releases the locking of the junction turnout constituting the crossover with the front section route, and then feeds back the unlocking state of the front section route to the self interlocking device;

[0092] Step S4.8, the self interlocking device judges whether the front section route is unlocked, if yes, goes to step S4.9, otherwise, returns to step S4.8;

[0093] Step S4.9, after the front section route is unlocked, the self interlocking device controls the rear section route to be unlocked with the train operation.

[0094] As shown in the figure, Figure 1 In the embodiment, the control and protection process of the transfer route through the third turnout SW3 and the second turnout SW2 is taken as an example for illustration:

[0095] 1, the route first passed by the train is the front section route Route 5, as shown in the green light band covered part in the figure, Figure 1 The front section route is managed by the CBTC mode interlocking device, and the route passed by the train later is the rear section route Route 6, as shown in the pink light band covered part in the figure, Figure 1 The rear section route is managed by the CTCS mode interlocking device.

[0096] 2, after the transfer route operation is handled, the CTCS mode interlocking device first locks the route Route 6 and the junction turnout SW1, and then opens the signal S8, and sends the signal opening state of S8 to the CBTC mode interlocking device;

[0097] 3, after the CBTC mode interlocking device receives the S8 opening information, the route Route 5 and the junction turnout SW4 are locked, and then the signal S1 is opened;

[0098] 4, after the train drives out of Route 5 according to the S1 opening state, the CBTC mode interlocking device unlocks Route 5, and sends the unlocking state of Route 5 to the CTCS mode interlocking device;

[0099] 5, after the train drives out of Route 6 and receives the Route 5 unlocking information, the CTCS mode interlocking device can unlock Route 6.

[0100] When the transfer route is handled, the two line dispatchers do not need to perform manual request approval of the turnout operation, and the dispatching system can automatically trigger the transfer route. The automation of the transfer route operation improves the efficiency of the double mode train transfer operation, and meets the public transportation operation demand of the city (suburban) railway.

[0101] The application adopts separate control of the connecting turnout, can meet the requirements of automatic triggering of the transfer route, improves the transfer efficiency of double-system trains, ensures the public transport interval, and simplifies the maintenance operation process of the connecting turnout. At the same time, the connecting turnout area route control and protection measures matched with the separate control of the connecting turnout ensure the safe operation of the train in the connecting turnout area. The application has been highly recognized by users in the Guangdong-Hong Kong-Macao Greater Bay Area and will soon be implemented in the lines of CTCS and CBTC interconnection in the Greater Bay Area.
