Turnout zone intrusion alarm apparatus and method

Abstract

The present invention provides a turnout zone intrusion alarm apparatus and method. Upon detecting that a train enters a turnout intrusion protection zone or detecting that the train leaves the turnout intrusion protection zone, the axle counters each send a corresponding axle entry signal or axle exit signal to a corresponding zone intrusion protection alarm device; if the turnout intrusion protection zone is idle, the zone intrusion protection alarm device receives an axle entry signal triggered by a communication vehicle having movement authorization, and if receiving an axle entry signal triggered by an intruding vehicle before receiving an axle exit signal triggered by the communication vehicle, then sends alarm information to an interlocking device; the interlocking device turns off an opened annunciator, and forwards the alarm information to a zone controller; the zone controller sends an instruction for invalidating the movement authorization, so that the communication vehicle is braked. In the present solution, the turnout zone intrusion protection alarm information can be directly determined on the basis of the axle entry signals and axle exit signals sent by the axle counters, so that compared with the prior art, the input information is simple, and the response speed is faster.

Description

Turnout area intrusion alarm device and method

[0001] The present application claims priority to the Chinese patent application No. 202411248628.3, filed on September 5, 2024, and entitled "Turnout area intrusion alarm device and method", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of safety protection, in particular to a turnout area intrusion alarm device and method. BACKGROUND

[0003] In the rail transit train control system, the turnout area intrusion protection is an important function of safety protection. At present, in the CBTC (Communication Based Train Control) system, the communication vehicle equipped with vehicle-ground communication facilities can determine its specific position and the communication vehicle has the functions of slip protection and retreat protection, which can effectively prevent the train from non-human intrusion into the turnout intrusion protection area and avoid the risk of side collision. However, in the CBTC system, there are some non-communication vehicles without vehicle-ground communication facilities, and on the other hand, the communication vehicle may also be interrupted due to failure, and based on the needs of operation, the vehicles are stored in the power-off storage line in the main line, which will lead to the mixed operation of the communication-based moving block train and the non-communication fixed block / quasi-moving block train. For non-communication vehicles, the accurate actual position cannot be obtained, and if the non-communication vehicle intrudes into the turnout intrusion protection area and continuously slips into the adjacent axle section (without signal protection) or occupies the turnout intrusion protection area due to some other reasons, the region controller may not be able to identify the safety risk in time during the operation period, which may cause the risk of train collision.

[0004] In the prior art, (publication number: CN107244336A) a large amount of information needs to be sent to the region controller, the calculation process is complex, and the response speed is slow.

[0060] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0061] In this application, the terms "comprise", "contain" or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, the element defined by the phrase "comprises a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0062] First, the terms appearing in this application are explained as shown in the following table:

[0063] As shown in Figure 1, a structure diagram of a turnout area intrusion alarm device disclosed in an embodiment of the application, the device comprises: a plurality of axle counters (i.e. axle counters J1 to Jn), an area intrusion protection alarm device 1, an interlocking device 2 and an area controller 3.

[0064] It should be noted that an axle counter is provided at each turnout entrance of the track turnout, and the track sections between the axle counters constitute a turnout intrusion protection area.

[0065] As shown in Figure 2, a schematic diagram of a single reversing turnout area disclosed in an embodiment of the application.

[0066] Among them, J1 to J4 respectively represent each axle counter provided at the entrance of the single reversing turnout, and the track sections between the axle counters J1, J2, J3 and J4 constitute a turnout intrusion protection area.

[0067] S1 to S4 respectively represent each signal provided at the entrance of the turnout, P01 and P02 represent the turnout, the turnout has a positioning state and a reverse state, and P01 and P02 in Figure 2 are in the reverse state.

[0068] Taking P01 as an example, the positioning state means that the turnout is moved to the S1 and S4 connection state, and the connection between S4 and S2 is disconnected, at this time the train can run from S4 to S1, and cannot run to S2; the reverse state means that the turnout is moved to the S4 and S2 connection state, and the connection between S4 and S1 is disconnected, at this time the train can run from S4 to S2, and cannot run to S1.

[0069] The axle counter J1 to Jn is used to send an entry axle signal to the area intrusion protection alarm device when detecting that a train enters the turnout intrusion protection area, and to send an exit axle signal to the area intrusion protection alarm device when detecting that a train leaves the turnout intrusion protection area.

[0070] The regional intrusion protection alarm device 1 is used for sending alarm information to the interlocking device 2 if the entry axle signal triggered by the communication vehicle with mobile authorization is received when the turnout intrusion protection region is idle, and the entry axle signal triggered by the intruding vehicle is received before the exit axle signal triggered by the communication vehicle is received.

[0071] The entry axle signal triggered by the communication vehicle and the entry axle signal triggered by the intruding vehicle are from two different axle counters; the mobile authorization is used to indicate that the communication vehicle passes through the turnout intrusion protection region.

[0072] It can be understood that, since the turnout intrusion protection region is in an idle state without vehicles before the communication vehicle enters, when the exit axle signal is received before the entry axle signal of the intruding vehicle is received, it can be determined that the communication vehicle has already driven out of the turnout intrusion protection region.

[0073] It should be noted that in the automatic train operation mode, the CBTC system provides the vehicle automatic protection system ATP and the vehicle automatic control system ATC, and the safety of the communication vehicle can be ensured by the CBTC system; but in the manual train operation mode, there is no ATP protection, and the safety of the communication vehicle is completely ensured by the driver. In order to ensure safety, when the communication vehicle turnout route is handled and the communication vehicle is about to enter the turnout or drive on the turnout after having the mobile authorization, if an intruding vehicle enters other entrances of the turnout, the regional intrusion protection alarm device 1 needs to send alarm information.

[0074] Preferably, the regional intrusion protection alarm device 1 marks the axle counter that sends the entry axle signal triggered by the communication vehicle when the entry axle signal triggered by the communication vehicle is received, so as to determine whether the entry axle signal triggered by the intruding vehicle is from the non-marked axle counter.

[0075] It should be noted that the communication vehicle refers to a train equipped with a communication device and controlled by the CBTC system, and the communication vehicle can send a route request to the interlocking device 2, so as to obtain the mobile authorization returned by the interlocking device 2, and then drive to the position specified by the mobile authorization.

[0076] In an embodiment, the regional intrusion protection alarm device 1 determines whether there is a train in the turnout intrusion protection region in real time; if not, it is determined that the turnout intrusion protection region is in an idle state; if yes, it is determined that the turnout intrusion protection region is in an occupied state, and the occupation information is sent to the interlocking device 2.

[0077] When the interlocking device 2 receives the occupation information, the signal that has been opened is closed, and the occupation information is forwarded to the regional controller 3.

[0078] When the regional controller 3 receives the occupation information, the mobile authorization is updated for the target communication vehicle that has received the mobile authorization and has not yet entered the turnout intrusion protection region, so that the updated mobile authorization indicates the target communication vehicle to drive to the entrance position of the turnout intrusion protection region.

[0079] Preferably, when the turnout intrusion protection area reverts to the idle state, the area intrusion protection alarm device 1 sends a release command to the interlocking device 2, the closed signal machine reverts to the open state, and the area controller 3 forwards the release command to the interlocking device 2, so that the area controller 3 restores the movement authorization of the communication vehicle.

[0080] Preferably, the area intrusion protection alarm device 1 determines whether there is a train in the turnout intrusion protection area in real time as follows:

[0081] Real-time record the number of received entry shaft signals and the number of exit shaft signals; Real-time determine whether the number of entry shaft signals is equal to the number of exit shaft signals; If yes, it is determined that there is no train in the turnout intrusion protection area; If not, it is determined that there is a train in the turnout intrusion protection area.

[0082] Preferably, the area intrusion protection alarm device 1 sends an alarm signal to the interlocking device 2 through a safety communication system.

[0083] The interlocking device 2 is used to close the opened signal machine when receiving the alarm information, and forwards the alarm information to the area intrusion protection alarm device 3.

[0084] It should be noted that the signal machine is a trackside basic device of railway and urban rail transit, which is used to indicate the running condition of the incoming and outgoing trains, complete the interlocking task, and ensure the safety and reliability of the route. Closing the signal machine means the closed state of the railway signal, without displaying the running condition of the train, such as red light or blue light. The open signal machine means the open state of the railway signal, which has a display indicating the running condition of the train, such as green light, green-yellow light, red-white guidance signal or double yellow light, etc.

[0085] It can be understood that after the movement authorization is given to the communication vehicle, the interlocking device 2 synchronously opens the corresponding signal machine.

[0086] The area controller 3 is used to receive the route request sent by the communication vehicle, generate a movement authorization and send it to the communication vehicle; When receiving the alarm information, an invalid instruction for the movement authorization is sent to the communication vehicle, so that the communication vehicle brakes.

[0087] The main function of the area controller 3 is to generate a movement authority (MA) for a communication vehicle located within the control area of the area controller 3 according to the received route request, various state information and data information from the VOBC (vehicle controller), CI (interlocking device 2), ATS (automatic train control system) and DSU (data storage unit), and timely send the movement authority to the vehicle VOBC device through the data communication system to control the operation of the communication vehicle. The area controller 3 is responsible for monitoring and controlling the movement of the communication vehicle in a specific area, ensuring that the train travels according to the predetermined path and speed, and ensuring the safety and efficiency of train operation.

[0088] It can be understood that the area controller 3 generates a movement authority and sends it to the communication vehicle when the switch intrusion protection area is idle, and the communication vehicle will immediately enter the switch intrusion protection area. The next axle entry signal received by the area intrusion protection alarm device 1 by default is triggered by the communication vehicle receiving the movement authority. Even if the next axle entry signal is triggered by the intruding vehicle, the area controller 3 will receive the occupancy information and modify the movement authority about to enter the switch intrusion protection area, so that the communication vehicle waits outside the switch intrusion protection area until the occupancy is released, and no danger will occur.

[0089] In an embodiment, the area intrusion protection alarm device 1 is further configured to: when receiving the exit axle signal triggered by the intruding vehicle, send a release instruction for the alarm signal to the interlocking device 2 through the interlocking device 2, so that the signal machine is reopened and the communication vehicle resumes operation.

[0090] In an embodiment, the area intrusion protection alarm device 1 is further configured to:

[0091] If the first train triggered entry axle signal and the second train triggered entry axle signal are received at the same time when the switch intrusion protection area is idle, a special alarm information is sent to the interlocking device 2; when the first train triggered exit axle signal and the second train triggered exit axle signal are received, a release instruction for the special alarm signal is sent to the interlocking device 2.

[0092] It should be noted that the first train and the second train enter the switch intrusion protection area at the same time, and the area intrusion protection alarm device 1 cannot distinguish between the communication vehicle and the intruding vehicle. At this time, the area intrusion protection alarm device 1 will also alarm, and even if the intruding vehicle exits the switch intrusion protection area, the alarm cannot be cancelled. At this time, the communication vehicle also needs to exit the switch intrusion protection area to cancel the alarm, or manually reset to cancel the alarm.

[0093] The interlocking device 2 is further configured to:

[0094] When receiving the special alarm information, the opened signal machine is closed, and the special alarm information is forwarded to the area controller 3; when receiving the release instruction, the release instruction is sent to the area controller 3, and the signal machine is reopened.

[0095] The regional controller 3 is further configured to:

[0096] When receiving the special alarm information, the regional controller 3 sends an invalid instruction for the movement authorization to the communication vehicle in the first train and the second train that has the movement authorization, so that the communication vehicle brakes; when receiving the release instruction, the regional controller 3 restores the movement authorization of the communication vehicle, so that the communication vehicle resumes running.

[0097] It can be understood that, since the movement authorization of the communication vehicle is generated by the regional controller 3, the regional controller 3 can distinguish the communication vehicle in the first train and the second train.

[0098] The following will take the single turnout area shown in FIG. 2 as an example to introduce various alarm scenarios:

[0099] As shown in FIG. 3, it is a first alarm scenario diagram of the single turnout area disclosed in the embodiment of the present application.

[0100] When the communication vehicle (train 1) passes the axle counter J4 first, the intruding vehicle (train 2) passes the axle counter J1, the axle counter J2 or the axle counter J3, at this moment, the regional intrusion protection alarm device 1 alarms, the alarm information is sent to the interlocking device 2 through the safety communication system, the interlocking device 2 forwards the alarm information to the regional controller 3, the regional controller 3 sends an invalid instruction for the movement authorization (MA) to the communication vehicle, so that the communication vehicle stops urgently. When the intruding vehicle exits the corresponding axle counter, the alarm information is cancelled.

[0101] In FIG. 3, the arc represents the position where the movement authorization instructs the communication vehicle to run, in the embodiment of the present application, the movement authorization represented by the arc is invalidated, that is, the invalid MA.

[0102] As shown in FIG. 4, it is a second alarm scenario diagram of the single turnout area disclosed in the embodiment of the present application.

[0103] When the communication vehicle (train 1) passes the axle counter J4, the intruding vehicle (train 2) also passes the axle counter J1, the axle counter J2 or the axle counter J3 at the same time, at this moment, the regional intrusion protection alarm device 1 alarms, the alarm information is sent to the interlocking device 2 through the safety communication system, the interlocking device 2 forwards the alarm information to the regional controller 3, the regional controller 3 sends an invalid instruction for the movement authorization (MA) to the communication vehicle, so that the communication vehicle stops urgently. When the intruding vehicle exits the corresponding axle counter and the communication vehicle exits the turnout intrusion protection area, the alarm information is cancelled, or the regional intrusion protection alarm device 1 is manually reset to cancel the alarm.

[0104] In FIG. 4, the communication vehicle exits the turnout intrusion protection area, that is, the communication vehicle exits the axle counter J4 or the communication vehicle exits the axle point J2.

[0105] As shown in Figure 5, it is a third alarm scene diagram of the single turnback turnout area disclosed by the embodiment of the present application.

[0106] When the communication vehicle (train 1) does not pass the counting point J4, the intruding vehicle (train 2) passes the counting device J1, the counting device J2 or the counting device J3, at this moment, the area intrusion protection alarm device 1 outputs the occupation information, the interlocking device 2 receives the occupation information and forwards it to the area controller 3, and the area controller 3 sends the withdrawal instruction to the communication vehicle, so that the movement authority is updated to the signal S4. Since the communication vehicle does not pass the counting point J4, only one counting device in the turnout intrusion protection area detects the train passing, and the area intrusion protection alarm device 1 does not alarm.

[0107] In the embodiment of the present application, the movement authority represented by the arc line is withdrawn, that is, the withdrawal MA.

[0108] It should be noted that the turnout intrusion protection area types include the main line alternating turnback turnout area, the branch line turnout area, the main line storage track area, the depot entrance and exit area and the depot area, etc. Various types can be simplified as a combination state of the single turnback turnout area, and the alarm scenarios of various types of protection areas will be introduced below.

[0109] As shown in Figure 6, it is an alarm scene diagram of the main line alternating turnback turnout area disclosed by the embodiment of the present application.

[0110] The main line alternating turnback turnout area type can be simplified as two single alternating turnback turnout protection areas, and each protection area performs turnout area intrusion protection alarm. The counting devices J1, J2, J3 and J4 can be combined into a turnout intrusion protection area 1, and when the turnouts P01 and P02 are both in the reverse position, the turnout area intrusion protection alarm is performed. The counting devices J3, J4, J5 and J6 can be combined into a turnout intrusion protection area 2, and when the turnouts P03 and P04 are both in the reverse position, the turnout area intrusion protection alarm is performed.

[0111] As shown in Figure 7, it is an alarm scene diagram of the branch line turnout area disclosed by the embodiment of the present application.

[0112] The branch line turnout area type can be equivalent to a single alternating turnback turnout protection area, and the turnout area intrusion protection alarm is performed. The counting devices J1, J2 and J4 can be combined into a turnout intrusion protection area, and when the turnouts P01 and P02 are both in the reverse position, the turnout area intrusion protection alarm is performed.

[0113] As shown in Figure 8, it is an alarm scene diagram of the main line storage track area disclosed by the embodiment of the present application.

[0114] The positive line storage track switch area type can be simplified and equivalent to two single alternating turn-back switch protection areas, and the switch area intrusion protection alarm is performed respectively. The axle counter J1, J4 and J5 can be combined into a switch intrusion protection area 1, and when the switch P03 is in the reverse position, the switch area intrusion protection alarm is performed. The axle counter J2, J3 and J5 can be combined into a switch intrusion protection area 2, and when the switch P03 is in the fixed position, the switch area intrusion protection alarm is performed.

[0115] As shown in FIG. 9, it is an alarm scene diagram of the vehicle depot entrance and exit area disclosed in the embodiment of the application.

[0116] The vehicle depot entrance and exit switch area type can be simplified and equivalent to two single alternating turn-back switch protection areas, and the switch area intrusion protection alarm is performed respectively. The axle counter J1, J3, J4 and J5 can be combined into a switch intrusion protection area 1, and when the switches P01 and P02 are in the reverse position, the switch area intrusion protection alarm is performed. The axle counter J2, J5 and J6 can be combined into a switch intrusion protection area 2, and when the switch P03 is in the reverse position, the switch area intrusion protection alarm is performed.

[0117] As shown in FIG. 10, it is an alarm scene diagram of the vehicle depot area disclosed in the embodiment of the application.

[0118] The axle counter J1, J3, J4, J5, J6, J7 and J8 can be combined into a switch intrusion protection area, and no matter the switches P01, P02, P03, P04, P05, P06 and P07 are in the positive position or the reverse position, the switch area intrusion protection alarm is performed.

[0119] It can be understood that through the modular design, according to the different switch scenes on site, flexible configuration can be realized, and various switch intrusion protection area types can be met.

[0120] Based on the above-mentioned switch area intrusion alarm device disclosed in the embodiment of the application, in the present scheme, according to the entry axle signal and the exit axle signal sent by the axle counter, the switch area intrusion protection alarm information can be directly judged, and compared with the prior art, the response speed is faster.

[0121] Corresponding to the above-mentioned switch area intrusion alarm device disclosed in the embodiment of the application, as shown in FIG. 11, it is a flow chart of a switch area intrusion alarm method disclosed in the embodiment of the application, including the following steps:

[0122] Step S1: When the axle counter detects that the train enters the switch intrusion protection area, the entry axle signal is sent to the area intrusion protection alarm device, and when the train leaves the switch intrusion protection area, the exit axle signal is sent to the area intrusion protection alarm device.

[0123] Each of the track switches is provided with an axle counter, and track sections between the axle counters constitute a switch intrusion protection area.

[0124] Step S2: If the regional intrusion protection alarm device receives an entry axle signal triggered by the communication vehicle with a movement authorization when the switch intrusion protection area is idle, and receives an entry axle signal triggered by the intruding vehicle before receiving an exit axle signal triggered by the communication vehicle, the regional intrusion protection alarm device sends alarm information to the interlocking device.

[0125] The entry axle signal triggered by the communication vehicle and the entry axle signal triggered by the intruding vehicle come from two different axle counters; the movement authorization is generated by the regional controller receiving a route request sent by the communication vehicle, and is sent to the communication vehicle; the movement authorization is used to indicate that the communication vehicle passes through the switch intrusion protection area.

[0126] Step S3: When the interlocking device receives the alarm information, the interlocking device closes the opened signal and forwards the alarm information to the regional controller.

[0127] Step S4: When the regional controller receives the alarm information, the regional controller sends an invalid instruction for the movement authorization to the communication vehicle, so that the communication vehicle brakes.

[0128] After step S4 is executed, when the regional intrusion protection alarm device receives an exit axle signal triggered by the intruding vehicle, the regional intrusion protection alarm device sends a release instruction for the alarm signal to the regional controller through the interlocking device, so that the signal is reopened, and the communication vehicle resumes operation.

[0129] In an embodiment, the switch intrusion alarm method further comprises:

[0130] The regional intrusion protection alarm device determines whether there is a train in the switch intrusion protection area in real time; if not, it is determined that the switch intrusion protection area is in an idle state; if yes, it is determined that the switch intrusion protection area is in an occupied state, and the interlocking device is sent with an occupancy information.

[0131] Specifically, the process of determining whether there is a train in the switch intrusion protection area in real time by the regional intrusion protection alarm device comprises:

[0132] The regional intrusion protection alarm device records the number of received entry axle signals and the number of exit axle signals; determines whether the number of entry axle signals is equal to the number of exit axle signals in real time; if yes, it is determined that there is no train in the switch intrusion protection area; if not, it is determined that there is a train in the switch intrusion protection area.

[0133] When the interlocking device receives the occupancy information, the interlocking device closes the opened signal and forwards the occupancy information to the regional controller.

[0134] When the regional controller receives the occupation information, the mobile authorization is updated for the target communication vehicle that has received the mobile authorization and has not entered the turnout intrusion protection area, so that the updated mobile authorization indicates that the target communication vehicle drives to the entrance position of the turnout intrusion protection area.

[0135] It should be noted that the explanation of each step is described in the above embodiments of the application, and will not be repeated here.

[0136] Based on the above-mentioned switch area intrusion alarm method disclosed in the embodiments of the application, in the present scheme, the switch area intrusion protection alarm information can be directly judged according to the axle-in signal and the axle-out signal sent by the axle counter, and the response speed is faster than that of the prior art.
