[0046] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0047] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0048] Figure 1 1 is a schematic diagram of the structure of a vehicle runaway monitoring system provided by an embodiment of the present invention; Figure 2 This is a flow chart of a vehicle runaway monitoring method provided by an embodiment of the present invention. This embodiment is applicable to monitoring whether a vehicle parked on a track runs away in a railway hump yard. The method can be executed by a vehicle runaway monitoring device, which can be implemented in the form of hardware and / or software. Figure 1 As shown, the vehicle runaway monitoring system 100 provided in the embodiment of the present invention includes: a host computer 1, a state acquisition device 2, a current track 3, a first track circuit 4, a second track circuit 5, a first switch 6 and a first parking device 7.

[0049] Specifically, the state acquisition device 2 is connected to the host computer 1, the first track circuit 4 and the second track circuit 5 respectively, wherein the state acquisition device 2 and the host computer 1 can be connected based on the controller area network bus (CAN), the local interconnect network (LIN) or Ethernet. Along the extension direction X of the current track 3, the current track 3 is provided with N parking devices, N is a natural number greater than or equal to 2, the parking device with the smallest distance from the first switch 6 is the first parking device 7, the setting interval of the first track circuit 4 in the current track 3 covers the setting interval of the first parking device 7 in the current track 3, and the second track circuit 5 is located in the current track 3 and on the side of the first track circuit 4 close to the first switch 6. The state acquisition device 2 collects the occupation status of the first track circuit 4 and the second track circuit 5, and then transmits the occupation status to the host computer 1 for analysis to realize the monitoring of vehicle slippage.

[0050] like Figure 1 and Figure 2 As shown, the vehicle runaway monitoring method based on the above structure comprises the following steps:

[0051] S110, respectively obtain the occupation status of the first track circuit and the occupation status of the second track circuit in the current track.

[0052] Among them, the setting interval of the first track circuit 4 in the current track 3 covers the setting interval of the first parking device 7 in the current track 3, and the second track circuit 5 is located in the current track 3 and on the side of the first track circuit 4 close to the first switch 6.

[0053] Specifically, the parking device on the current track 3 is a key safety device in the railway transportation system. Multiple parking devices are controlled in an integrated manner. When it is necessary to work on the vehicle, multiple parking devices are controlled at the same time through their internal mechanical structures to generate braking force on the slipping vehicle, so that the vehicle can quickly decelerate and stop when it reaches the predetermined position, ensuring that the train is accurately and safely parked at the designated position. When the vehicle slips, the vehicle will slide along the extension direction X of the current track 3 toward the first switch 6. According to the trajectory of the vehicle slipping, the first parking device 7 is the last parking device passed by the slipping vehicle.

[0054] The first track circuit 4 and the second track circuit 5 are both independently set, and the occupation state of the first track circuit 4 and the occupation state of the second track circuit 5 in the current track 3 are respectively obtained through the state acquisition device 2. Exemplarily, the state acquisition device 2 may include a pressure sensor, and when the vehicle does not slip, the first track circuit 4 and the second track circuit 5 are not occupied, and the pressure signal thereon is less than the threshold pressure; when the vehicle slips to the first track circuit 4 or the second track circuit 5, the first track circuit 4 or the second track circuit 5 is occupied, and the vehicle will generate a pressure signal greater than or equal to the threshold pressure at the first track circuit 4 or the second track circuit 5, and then the state acquisition device 2 respectively obtains the pressure signal of the first track circuit 4 and the pressure signal of the second track circuit 5 in the current track 3, so as to realize the acquisition of the occupation state of the first track circuit 4 and the occupation state of the second track circuit 5.

[0055] S120: Determine the vehicle runaway state of the current track according to the occupation state of the first track circuit and the occupation state of the second track circuit.

[0056] Specifically, in the railway hump yard, the first parking device 7 generally does not participate in the braking work of parking the vehicle, that is, the first parking device 7 does not park the vehicle. Therefore, when the vehicle does not slip, the first track circuit 4 and the second track circuit 5 are not occupied; and when the parked vehicle slips along the extension direction X of the current track 3 toward the first switch 6, the slipping vehicle will occupy the first track circuit 4 and / or the second track circuit 5. The upper computer 1 determines the vehicle slipping state of the current track 3 through the occupation state of the first track circuit and the occupation state of the second track circuit obtained by the state acquisition device 2. If the occupation state of the first track circuit 4 and the occupation state of the second track circuit 5 are both idle states, the vehicle slipping state of the current track 3 is determined to be a non-slipping state; if the occupation state of the first track circuit 4 and / or the occupation state of the second track circuit 5 are occupied states, the vehicle slipping state of the current track 3 is determined to be a slipping state.

[0057] This embodiment obtains the occupation status of the first track circuit and the occupation status of the second track circuit respectively, determines the vehicle runaway status of the current track according to the occupation status of the first track circuit and the occupation status of the second track circuit, and monitors the section where the parking device of the current track is located, so as to realize real-time monitoring of the vehicle runaway situation, ensure the timeliness of vehicle runaway monitoring, enable the station attendant to timely understand the position of the vehicle in the current track, and take corresponding measures in advance in case of vehicle runaway, thereby improving driving safety and emergency response capabilities and avoiding the occurrence of safety accidents.

[0058] Based on the above embodiments, Figure 3 is a flow chart of another vehicle runaway monitoring method provided by an embodiment of the present invention, Figure 3 The vehicle runaway monitoring method shown in the figure illustrates how to determine the vehicle runaway state of the current track according to the occupation state of the first track circuit and the occupation state of the second track circuit. Figure 1 and Figure 3 As shown, the vehicle runaway monitoring method comprises the following steps:

[0059] S210, respectively obtain the occupation status of the first track circuit and the occupation status of the second track circuit in the current track.

[0060] Among them, the setting interval of the first track circuit 4 in the current track 3 covers the setting interval of the first parking device 7 in the current track 3, and the second track circuit 5 is located in the current track 3 and on the side of the first track circuit 4 close to the first switch 6.

[0061] Optionally, along the extension direction X of the current track 3 , the length of the first track circuit 4 and / or the second track circuit 5 is greater than or equal to the vehicle length.

[0062] Specifically, when a vehicle runs away along the extension direction X of the current track 3, the lengths of the first track circuit 4 and the second track circuit 5 are set to be greater than or equal to the length of the runaway vehicle, so that the monitoring system 100 can completely detect whether the entire body of the vehicle occupies the first track circuit 4 and / or the second track circuit 5, thereby reducing the possibility of false alarms and missed alarms of vehicle runaway and improving the accuracy of monitoring.

[0063] Exemplarily, along the extension direction X of the current track 3, the length of the first track circuit 4 and / or the second track circuit 5 can be 25m, and the second track circuit 5 can be set at 16-18m from the exit of the first parking device 7, which is not specifically limited in this embodiment.

[0064] S220: When the occupation state of the first track circuit is the occupied state, it is determined that the vehicle runaway state of the current track is the runaway warning state.

[0065] Specifically, when the parked vehicle slips along the extension direction X of the current track 3 toward the first switch 6, the parked vehicle will move from other parking devices on the current track 3 to the first parking device 7. At this time, the vehicle will occupy the first track circuit 4, and the occupation state of the first track circuit 4 changes from the initial idle state to the occupied state. At this time, the first track circuit 4 obtained by the state acquisition device 2 is in the occupied state, indicating that at least part of the main body of the vehicle has slipped to the first track circuit 4, and then the state acquisition device 2 transmits the information that the first track circuit 4 is in the occupied state to the host computer 1. Since the first track circuit 4 is located at the first parking device 7, the slipping vehicle at this time is still a certain distance from the first switch 6, and the slipping vehicle still has a certain time interval to rush out of the first switch 6. The host computer 1 can determine the vehicle slipping state of the current track 3 as the slipping warning state according to the occupied state of the first track circuit 4. The station staff can take corresponding preventive measures for the current track 3 according to the slipping warning state to ensure driving safety and prevent accidents.

[0066] Since at least part of the body of the runaway vehicle is located at the first parking device 7 in the runaway warning state, illustratively, when the staff determines that the vehicle's runaway state is the runaway warning state, they can brake the vehicle that has runaway through the first parking device 7 or open a safety line at the first switch 6 to stop the vehicle from continuing to run away and avoid safety accidents caused by the vehicle running away.

[0067] S230: When the occupation state of the second track circuit is the occupied state, it is determined that the vehicle runaway state of the current track is the runaway state.

[0068] Specifically, when the runaway vehicle passes through the first track circuit 4 along the extension direction X of the current track 3 and continues to runaway toward the first switch 6, the runaway vehicle will move to the second track circuit 5 on the current track 3. At this time, the vehicle will occupy the second track circuit 5, and the occupation state of the second track circuit 5 will change from the initial idle state to the occupied state. At this time, the second track circuit 5 obtained by the status acquisition device 2 is in an occupied state, indicating that at least part of the main body of the vehicle has slipped to the second track circuit 5, and then the status acquisition device 2 transmits the information that the second track circuit 5 is in an occupied state to the host computer 1. Since the second track circuit 5 is located between the first parking device 7 and the first switch 6, the distance between the slipping vehicle and the first switch 6 at this time is relatively close, and the vehicle has slipped a large distance. During the slipping period, the gravitational potential energy of the vehicle is converted into kinetic potential energy, which makes the slipping vehicle have a greater moving speed, and the braking measures to be taken should also be stronger. The host computer 1 can determine the vehicle slipping state of the current track 3 as a slipped state according to the occupied state of the second track circuit 5, and the station staff can take corresponding emergency measures for the current track 3 according to the slipped state to ensure driving safety and prevent accidents.

[0069] Since at least part of the main body of the slipping vehicle is located at the second track circuit 5 in the slipping state, for example, when the staff determines that the vehicle is in the slipping state, they can organize personnel to use existing anti-slip equipment (such as tightening the handbrake, placing iron shoes or anti-slip sleepers, etc.) to perform emergency braking on the slipping vehicle to stop the vehicle from continuing to slip and avoid safety accidents caused by the vehicle slipping.

[0070] In this embodiment, when the first track circuit is in the occupied state, the vehicle runaway state of the current track is determined as the runaway warning state; when the second track circuit is in the occupied state, the vehicle runaway state of the current track is determined as the runaway state, so that the staff can quickly understand the runaway situation of the vehicle, can take corresponding countermeasures for different runaway situations, reasonably optimize the resource allocation in the countermeasure plan, and improve the monitoring accuracy of vehicle runaway and the safety of station operation.

[0071] Based on the above embodiments, Figure 4 is a flow chart of another vehicle runaway monitoring method provided by an embodiment of the present invention, Figure 4 The method for monitoring vehicle slipping describes how to obtain the occupation status of the first track circuit and the occupation status of the second track circuit in the current track. Figure 1 and Figure 4 The vehicle runaway monitoring method comprises the following steps:

[0072] S310: Collect a first electrical signal of a first track circuit based on a first acquisition module, and determine an occupation state of the first track circuit according to the first electrical signal.

[0073] Specifically, the state acquisition device 2 may include a first acquisition module, which may be connected to the first track circuit 4, and the first track circuit 4 and the second track circuit 5 are independently arranged. When the occupation state of the first track circuit 4 is different, the first electrical signal acquired by the first acquisition module is different. Therefore, the first electrical signal of the first track circuit 4 acquired at a certain moment can represent the occupation state of the first track circuit 4 at this moment. The first electrical signal of the first track circuit 4 is acquired by the first acquisition module to determine the occupation state of the first track circuit 4 at this moment according to the first electrical signal.

[0074] Exemplarily, the first acquisition module may be a current sensor, and the first track circuit 4 may be in a normal state when no vehicle passes, and the first acquisition module acquires the first electrical signal of the first track circuit 4 as the rated current; when a runaway vehicle passes, the contact between the wheels of the runaway vehicle and the current track will form a low-resistance electrical connection, causing the current of the first track circuit 4 to decrease or be interrupted, and the first acquisition module acquires the first electrical signal of the first track circuit 4 as a non-rated current. By acquiring the current size of the first track circuit 4 at a certain moment, the occupancy state of the first track circuit at this time can be determined. It should be noted that the above only exemplarily shows the way of acquiring the first electrical signal of the first track circuit through the first acquisition module, and does not serve as a specific limitation of this embodiment, and this embodiment does not make specific limitations on this.

[0075] S320: Collect a second electrical signal of the second track circuit based on the second acquisition module, and determine an occupation state of the second track circuit according to the second electrical signal.

[0076] Specifically, the state acquisition device 2 may further include a second acquisition module, which may be connected to the second track circuit 5, and the first track circuit 4 and the second track circuit 5 are independently arranged. When the occupation state of the second track circuit 5 is different, the second electrical signal acquired by the second acquisition module is different. Therefore, the second electrical signal of the second track circuit 5 acquired at a certain moment may represent the occupation state of the second track circuit 5 at this moment. The second electrical signal of the second track circuit 5 is acquired by the second acquisition module to determine the occupation state of the second track circuit 5 at this moment according to the second electrical signal.

[0077] Exemplarily, the second acquisition module may be a current sensor, and the second track circuit 5 may be in a normal state when no vehicle passes, and the second acquisition module acquires the second electrical signal of the second track circuit 5 as the rated current; when a runaway vehicle passes, the contact between the wheels of the runaway vehicle and the current track will form a low-resistance electrical connection, causing the current of the second track circuit 5 to decrease or be interrupted, and the second acquisition module acquires the second electrical signal of the second track circuit 5 as a non-rated current. By acquiring the current magnitude of the second track circuit 5 at a certain moment, the occupancy state of the second track circuit at this time can be determined. It should be noted that the above only exemplarily shows the method of obtaining the second electrical signal of the second track circuit through the second acquisition module, and does not serve as a specific limitation of this embodiment, and the second acquisition module and the first acquisition module may be the same or different, and this embodiment does not make specific limitations on this.

[0078] S330: Determine the vehicle runaway state of the current track according to the occupation state of the first track circuit and the occupation state of the second track circuit.

[0079] In this embodiment, a first acquisition module is used to acquire a first electrical signal of a first track circuit so as to determine an occupied state of the first track circuit, and a second acquisition module is used to acquire a second electrical signal of a second track circuit so as to determine an occupied state of the second track circuit, so as to realize independent acquisition of the occupied states of the first track circuit and the second track circuit, respectively, thereby improving the accuracy of vehicle runaway monitoring and avoiding the possibility of false detection and missed detection of vehicle runaway.

[0080] Optional, continue to refer to Figure 1 , determining an occupation state of a first track circuit according to a first electrical signal, comprising:

[0081] If the first acquisition module does not acquire the first electrical signal, the occupation state of the first track circuit is determined to be an occupied state.

[0082] Specifically, when the first track circuit 4 is not occupied by a runaway vehicle, the first track circuit 4 is in an idle state, and the current of the first track circuit 4 flows to the first acquisition module, and then the first acquisition module can realize the acquisition of the first electrical signal of the first track circuit 4; when the first track circuit 4 is occupied by a runaway vehicle, the current of the first track circuit 4 will flow to the axle of the runaway vehicle, so that the first acquisition module cannot acquire the first electrical signal. If the first acquisition module can acquire the first electrical signal, it indicates that no vehicle has changed the current propagation direction of the first track circuit 4, and the occupation state of the first track circuit 4 is determined to be an idle state; if the first acquisition module cannot acquire the first electrical signal, it indicates that there is a runaway vehicle above the first track circuit 4, and at least part of the main body of the vehicle has moved to the first track circuit 4, causing the runaway vehicle to change the current propagation direction of the first track circuit 4, and the occupation state of the first track circuit 4 is determined to be an occupied state.

[0083] For example, when the vehicle parked in the current track 3 has not run away, there is no vehicle at the first parking device 7 where the first track circuit 4 is located, and the current in the first track circuit 4 can flow to the first relay of the first acquisition module, so that the first relay is excited and drives the contact to be attracted, and the first acquisition module and the first track circuit 4 are connected, so that the first acquisition module can collect the first electrical signal of the first track circuit 4, and determine that the first track circuit 4 is in an idle state at this time; when there is a runaway vehicle occupying the section of the first track circuit 4, the current in the first track circuit 4 flows to the axle of the runaway vehicle, resulting in no current flowing to the first relay of the first acquisition module, causing the first relay to lose current and lose magnetism, and drive the contact to fall, disconnecting the connection between the first acquisition module and the first track circuit 4, and the first acquisition module cannot collect the first electrical signal of the first track circuit 4, so as to determine that the first track circuit 4 is in an occupied state at this time. Whether the first acquisition module collects the first electrical signal is determined to determine whether there is a vehicle occupying the section of the first track circuit 4.

[0084] Optional, continue to refer to Figure 1 , determining the occupation state of the second track circuit according to the second electrical signal, including:

[0085] If the second acquisition module does not acquire the second electrical signal, the occupation state of the second track circuit is determined to be an occupied state.

[0086] Specifically, when the second track circuit 5 is not occupied by a runaway vehicle, the second track circuit 5 is in an idle state, and the current of the second track circuit 5 flows to the second acquisition module, and then the second acquisition module can realize the acquisition of the second electrical signal of the second track circuit 5; when the second track circuit 5 is occupied by a runaway vehicle, the current of the second track circuit 5 will flow to the axle of the runaway vehicle, so that the second acquisition module cannot acquire the second electrical signal. If the second acquisition module can acquire the second electrical signal, it indicates that no vehicle has changed the current propagation direction of the second track circuit 5, and the occupation state of the second track circuit 5 is determined to be an idle state; if the second acquisition module cannot acquire the second electrical signal, it indicates that there is a runaway vehicle above the second track circuit 5, and at least part of the main body of the vehicle has moved to the second track circuit 5, causing the runaway vehicle to change the current propagation direction of the second track circuit 5, and the occupation state of the second track circuit 5 is determined to be an occupied state.

[0087] For example, when the vehicle parked on the current track 3 has not run away, there is no vehicle at the second track circuit 5, and the current in the second track circuit 5 can flow to the second relay of the second acquisition module, so that the second relay is excited and drives the contact to be attracted, and the second acquisition module and the second track circuit 5 are connected, so that the second acquisition module can collect the second electrical signal of the second track circuit 5, and determine that the second track circuit 5 is in an idle state at this time; when there is a runaway vehicle occupying the section of the second track circuit 5, the current in the second track circuit 5 flows to the axle of the runaway vehicle, resulting in no current flowing to the second relay of the second acquisition module, causing the second relay to lose current and lose magnetism, and drive the contact to fall, disconnecting the connection between the second acquisition module and the second track circuit 5, and the second acquisition module cannot collect the second electrical signal of the second track circuit 5, so as to determine that the second track circuit 5 is in an occupied state at this time. Whether the second acquisition module collects the second electrical signal is determined to determine whether there is a vehicle occupying the section of the second track circuit 5.

[0088] Based on the above embodiments, Figure 5 is a flow chart of another vehicle runaway monitoring method provided by an embodiment of the present invention, Figure 5 The monitoring method of vehicle runaway is further described. Figure 1 and Figure 5 The vehicle runaway monitoring method comprises the following steps:

[0089] S410, respectively obtain the occupation status of the first track circuit and the occupation status of the second track circuit in the current track.

[0090] Among them, the setting interval of the first track circuit 4 in the current track 3 covers the setting interval of the first parking device 7 in the current track 3, and the second track circuit 5 is located in the current track 3 and on the side of the first track circuit 4 close to the first switch 6.

[0092] S430. Issue a warning based on the vehicle runaway status of the current track.

[0093] Specifically, the vehicle runaway status may include a non-runaway status, a runaway warning status and an already runaway status, wherein the non-runaway status may be that the vehicle is parked on the current track 3 and has not moved to the section of the first track circuit 4 and the second track circuit 5, and the vehicle on the current track 3 is parked safely; the runaway warning status may be that the vehicle has moved to the section of the first track circuit 4, indicating that a runaway trend has begun to appear. Although it has not yet reached the level of complete runaway, it needs to attract the attention of the staff; the already runaway status may be that the vehicle has moved to the section of the second track circuit 5 close to the first switch 6, and a relatively serious vehicle runaway phenomenon has occurred, and it is necessary to take immediate measures to brake the runaway vehicle. When the vehicle is in a non-runaway state, the current parking state of the vehicle in track 3 is normal, and no warning reminder is given; when the vehicle is in a runaway warning state, a warning reminder may be given to inform the staff to take warning measures for the vehicle to run away; when the vehicle is in a runaway state, the vehicle has completely run away, and therefore an alarm reminder needs to be given to remind the staff to take emergency measures for the vehicle to run away, so as to prevent an accident caused by the vehicle running away. The warning reminder may include but is not limited to at least one of a voice reminder, a buzzer reminder, a light reminder, etc., and this embodiment does not make any specific limitation on this.

[0094] Exemplarily, the warning reminder may include a buzzer reminder and a light reminder, wherein the buzzer reminder may include an intermittent buzzer sound and a continuous buzzer sound, and the light reminder may include a green light reminder, a yellow light reminder, and a red light reminder. When the vehicle is in the runaway warning state, an intermittent buzzer sound and a yellow light reminder may be issued to attract the attention of the staff, so as to intervene in the runaway warning state of the vehicle and avoid the runaway situation; when the vehicle is in the runaway state, a continuous buzzer sound and a red light reminder may be issued to warn the operator to eliminate the vehicle runaway situation in time to prevent the vehicle from running away and causing an accident.

[0095] This embodiment issues a warning based on the vehicle's runaway status, making it easier for staff to promptly detect abnormal vehicle parking conditions and take corresponding countermeasures, thereby improving the efficiency of vehicle runaway monitoring and driving safety, and avoiding accidents caused by vehicle runaway.

[0096] Optionally, after determining the vehicle runaway state of the current track according to the occupation state of the first track circuit and the occupation state of the second track circuit, the method includes:

[0097] The occupation status of the third track circuit and the occupation status of the fourth track circuit in the next track are respectively obtained; wherein the setting interval of the third track circuit in the next track covers the setting interval of the second parking device in the next track, and the fourth track circuit is located in the next track and on the side of the third track circuit close to the second turnout;

[0098] The vehicle runaway state of the next track is determined according to the occupation state of the third track circuit and the occupation state of the fourth track circuit.

[0099] Specifically, after determining the vehicle runaway status of the current track according to the occupation status of the first track circuit and the occupation status of the second track circuit, the vehicle runaway monitoring of the next track can be performed. By respectively obtaining the occupation status of the third track circuit and the occupation status of the fourth track circuit in the next track, and then determining the vehicle runaway status of the next track according to the occupation status of the third track circuit and the occupation status of the fourth track circuit, the vehicle runaway status of each track is systematically and continuously detected, ensuring that each track in the railway hump yard can be monitored in a timely manner, thereby improving the overall efficiency of maintaining railway traffic safety.

[0100] Based on the above embodiments, Figure 6 is a flow chart of another vehicle runaway monitoring method provided by an embodiment of the present invention. Figure 6 The monitoring method of vehicle runaway is further described. Figure 1 and Figure 6 The vehicle runaway monitoring method comprises the following steps:

[0101] S510, obtaining the parking device status of the current track.

[0102] S520: If the parking device is in the braking state, the operation of respectively acquiring the occupation state of the first track circuit and the occupation state of the second track circuit is performed on the current track.

[0103] S530: If the parking device status is in the relief state, the operation of obtaining the parking device status of the next lane is executed.

[0104] S540: Determine the vehicle runaway state of the current track according to the occupation state of the first track circuit and the occupation state of the second track circuit.

[0105] Specifically, the upper computer 1 can obtain the parking device status of the current track 3 from the parking device control system. Multiple parking devices are controlled in an integrated manner. When work needs to be done on the vehicle, the parking device control system can simultaneously control multiple parking devices to be in a braking state, and through its internal mechanical structure, it generates braking force on the sled vehicle, so that the vehicle can quickly decelerate and stop when it reaches the predetermined position, ensuring that the train is parked accurately and safely at the designated position; when a vehicle needs to pass normally on the current track 3, the parking device does not need to brake the vehicle, and the parking device control system can simultaneously control multiple parking devices to be in a relief state. Therefore, the parking device state obtained by the upper computer 1 from the parking device control system can represent whether the vehicle has a parking demand in the current track 3. If the parking device state is a relief state, it indicates that the current track 3 needs to be open to traffic normally and there is no need to monitor the vehicle slipping. Then the parking device state of the next track is obtained, and then the next track needs to be monitored for vehicle slipping according to the parking device state of the next track; if the parking device state is a braking state, it indicates that the current track 3 has a parking demand and needs to monitor the vehicle slipping, then the occupation state of the first track circuit 4 and the occupation state of the second track circuit 5 in the current track 3 are respectively obtained, and the vehicle slipping state of the current track 3 is determined according to the occupation state of the first track circuit 4 and the occupation state of the second track circuit 5, so as to realize the slipping monitoring of the vehicles parked in the current track 3. Exemplarily, the upper computer 1 and the parking device control system can communicate with each other by using RS232 or Ethernet interface.

[0106] Before performing vehicle runaway monitoring on the current track, this embodiment determines whether vehicle runaway monitoring is required for the current track by acquiring the parking device status of the current track, and filters the information of vehicles occupying the first track circuit and the second track circuit under normal traffic conditions, thereby improving the efficiency and accuracy of vehicle runaway monitoring.

[0108] The acquisition module 610 is used to respectively acquire the occupation status of the first track circuit and the occupation status of the second track circuit in the current track; wherein the setting interval of the first track circuit in the current track covers the setting interval of the first parking device in the current track, and the second track circuit is located in the current track and on the side of the first track circuit close to the first switch;

[0109] The determination module 620 is used to determine the vehicle runaway state of the current track according to the occupation state of the first track circuit and the occupation state of the second track circuit.
