[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the numbers 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.

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 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 structural diagram 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 has runaway 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 by 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. The connection between the state acquisition device 2 and the host computer 1 can be based on a controller area network (CAN), a 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, where N is a natural number greater than or equal to 2. The parking device with the shortest 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 overlaps the setting interval of the first parking device 7 in the current track 3. The second track circuit 5 is located in the current track 3 and on the side of the first track circuit 4 near the first switch 6. The state acquisition device 2 collects the occupancy status of the first track circuit 4 and the second track circuit 5, and then transmits the occupancy status to the host computer 1 for analysis to monitor vehicle slippage.

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

[0051] S110: Obtain the occupancy status of the first track circuit and the occupancy status of the second track circuit in the current track respectively.

[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 brakes on track 3 are critical safety features in the railway transportation system. Multiple parking brakes are controlled in an integrated manner. When work is required on a vehicle, these brakes are simultaneously controlled through their internal mechanical structures to apply braking force to the slipping vehicle, enabling the vehicle to quickly decelerate and stop upon reaching the predetermined position, ensuring the train is accurately and safely parked at the designated location. When a vehicle slips, it slides along the extension direction X of track 3 toward the first switch 6. Following the trajectory of the slipping vehicle, the first parking brake 7 is the last parking brake passed by the slipping vehicle.

[0054] The first track circuit 4 and the second track circuit 5 are both independently configured, and the occupancy status of the first track circuit 4 and the occupancy status 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. When the vehicle is not slipping, the first track circuit 4 and the second track circuit 5 are unoccupied, and the pressure signals on them are less than a 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 generates a pressure signal greater than or equal to the threshold pressure at the first track circuit 4 or the second track circuit 5. Then, the state acquisition device 2 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, thereby achieving the acquisition of the occupancy status of the first track circuit 4 and the second track circuit 5.

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

[0056] Specifically, in a railway hump yard, the first parking device 7 generally does not participate in the braking work for parking vehicles, that is, no vehicles are parked at the first parking device 7. Therefore, when the vehicle does not slip, the first track circuit 4 and the second track circuit 5 are not occupied. However, 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 by obtaining the occupation state of the first track circuit and the occupation state of the second track circuit from the status 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, 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, the vehicle slipping state of the current track 3 is determined to be a slipping state.

[0057] This embodiment obtains the occupancy status of the first track circuit and the occupancy status of the second track circuit respectively, determines the vehicle runaway status of the current track based on the occupancy status of the first track circuit and the occupancy status of the second track circuit, and monitors the section of the current track where the parking device is located to achieve real-time monitoring of the vehicle runaway situation. This ensures the timeliness of vehicle runaway monitoring and enables station attendants to promptly understand the position of the vehicle on the current track. In the event of a vehicle runaway, corresponding measures can be taken in advance, thereby improving driving safety and emergency response capabilities and avoiding the occurrence of safety accidents.

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

[0059] S210: Obtain the occupancy status of the first track circuit and the occupancy status of the second track circuit in the current track respectively.

[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 slips 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 slipped 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, reducing the possibility of false alarms and missed alarms of vehicle slippage and improving the accuracy of monitoring.

[0063] For example, 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. This embodiment does not specifically limit this.

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

[0065] Specifically, when a 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 occupancy state of the first track circuit 4 will change from the initial idle state to the occupied state. At this time, the state acquisition device 2 obtains that the first track circuit 4 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. The state acquisition device 2 then 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 is still a certain distance away from the first switch 6 at this time, and there is still a certain time interval for the slipping vehicle to rush out of the first switch 6. Based on the occupied state of the first track circuit 4, the host computer 1 can determine the vehicle slipping state of the current track 3 as a slipping warning state. Station staff can take corresponding preventive measures for the current track 3 based on the slipping warning state to ensure driving safety and prevent accidents.

[0066] Since at least part of the main body of the slipping vehicle is located at the first parking device 7 in the slipping warning state, for example, when the staff determines that the slipping state of the vehicle is the slipping warning state, they can brake the vehicle that has slipped through the first parking device 7 or open a safety line at the first switch 6 to stop the vehicle from continuing to slip and avoid safety accidents caused by the vehicle slipping.

[0067] S230: When the occupation state of the second track circuit is the occupied state, determine that the vehicle slipping state of the current track is the slipped state.

[0068] Specifically, when the runaway vehicle passes 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 the 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 the 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 slipping vehicle is closer to the first switch 6 at this time, 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 the slipped state according to the occupied state of the second track circuit 5. 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 vehicle is located at the second track circuit 5 in the slipped state, for example, when the staff determines that the vehicle has slipped, they can organize personnel to use existing anti-slip devices (such as tightening the handbrake, placing iron shoes or anti-slip sleepers, etc.) to perform emergency braking on the 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 to be in the runaway warning state; when the second track circuit is in the occupied state, the vehicle runaway state of the current track is determined to be in the runaway state. This allows staff to quickly understand the vehicle runaway situation and take corresponding countermeasures for different runaway situations, thereby rationally optimizing resource allocation in the countermeasure plan, thereby improving the accuracy of vehicle runaway monitoring and the safety of station operation.

[0071] Based on the above embodiments, Figure 4 This 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 is described below. It explains 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 slipping 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 occupancy 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. The first track circuit 4 and the second track circuit 5 are independently provided. When the occupancy 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 occupancy state of the first track circuit 4 at that moment. The first electrical signal of the first track circuit 4 is acquired by the first acquisition module, and the occupancy state of the first track circuit 4 at that moment is determined based on 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 magnitude of the first track circuit 4 at a certain moment, the occupancy state of the first track circuit at that moment can be determined. It should be noted that the above is only an exemplary display of the method of acquiring the first electrical signal of the first track circuit by 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 occupancy 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. The first track circuit 4 and the second track circuit 5 are independently provided. When the occupancy 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 can represent the occupancy state of the second track circuit 5 at that moment. The second electrical signal of the second track circuit 5 is acquired by the second acquisition module to determine the occupancy state of the second track circuit 5 at that moment based on the second electrical signal.

[0077] Exemplarily, the second acquisition module can be a current sensor, and the second track circuit 5 can be in a normal state when no vehicle passes, and the second acquisition module collects the second electrical signal of the second track circuit 5 as the rated current; when a slipping vehicle passes, the contact between the wheels of the slipping 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 collects the second electrical signal of the second track circuit 5 as a non-rated current. By collecting 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 exemplifies 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 can be the same or different, and this embodiment does not make specific limitations on this.

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

[0079] In this embodiment, a first acquisition module acquires a first electrical signal from a first track circuit to determine the occupancy status of the first track circuit, and a second acquisition module acquires a second electrical signal from a second track circuit to determine the occupancy status of the second track circuit. This enables independent acquisition of the occupancy status of the first track circuit and the second track circuit, thereby improving the accuracy of vehicle runaway monitoring and avoiding the possibility of false detection or missed detection of vehicle runaway.

[0080] Optional, continue to refer to Figure 1 , determining an occupancy state of the first track circuit according to the first electrical signal, including:

[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, thereby enabling the first acquisition module to acquire 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, thereby preventing the first acquisition module from acquiring 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 vehicle's main body 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 a vehicle parked on track 3 has not escaped, there is no vehicle at the first parking device 7 where the first track circuit 4 is located. The current in the first track circuit 4 can flow to the first relay of the first acquisition module, energizing the first relay and causing the contact to rise, connecting the first acquisition module and the first track circuit 4, enabling the first acquisition module to collect the first electrical signal of the first track circuit 4 and determining that the first track circuit 4 is now in an idle state. When a vehicle escapes within the section of the first track circuit 4, the current in the first track circuit 4 flows to the axle of the escaped vehicle, resulting in a lack of current flowing to the first relay of the first acquisition module. This causes the first relay to lose current and become demagnetized, causing the contact to fall, disconnecting the first acquisition module from the first track circuit 4. The first acquisition module is unable to collect the first electrical signal of the first track circuit 4, and thus determines that the first track circuit 4 is now in an occupied state. Whether the first acquisition module collects the first electrical signal is used to determine whether a vehicle is occupying the section of the first track circuit 4.

[0084] Optional, continue to refer to Figure 1 , determining the occupancy 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 in the second track circuit 5 flows to the second acquisition module, thereby enabling the second acquisition module to acquire the second electrical signal of the second track circuit 5. When the second track circuit 5 is occupied by a runaway vehicle, the current in the second track circuit 5 flows to the axle of the runaway vehicle, thereby preventing the second acquisition module from acquiring the second electrical signal. If the second acquisition module can acquire the second electrical signal, it indicates that no vehicle has changed the direction of current propagation in 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 vehicle's main body has moved to the second track circuit 5, causing the runaway vehicle to change the direction of current propagation in 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 a vehicle parked on track 3 has not run away, there is no vehicle in the second track circuit 5. The current in the second track circuit 5 can flow to the second relay of the second acquisition module, causing the second relay to be energized and causing the contact to be attracted, connecting the second acquisition module and the second track circuit 5, 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. When a vehicle runs away and occupies the section of the second track circuit 5, the current in the second track circuit 5 flows to the axle of the running vehicle, resulting in no current flowing to the second relay of the second acquisition module. The second relay loses current and demagnetizes, causing the contact to drop, disconnecting the second acquisition module from the second track circuit 5. The second acquisition module is unable to collect the second electrical signal of the second track circuit 5, and thus determines that the second track circuit 5 is in an occupied state. Whether the second acquisition module collects the second electrical signal is used to determine whether a vehicle is occupying the section of the second track circuit 5.

[0088] Based on the above embodiments, Figure 5 This 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 slipping is further explained. Figure 1 and Figure 5 The vehicle slipping monitoring method comprises the following steps:

[0089] S410: Obtain the occupancy status of the first track circuit and the occupancy status of the second track circuit in the current track respectively.

[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.

[0091] S420: Determine the vehicle slipping state of the current track according to the occupancy state of the first track circuit and the occupancy state of the second track circuit.

[0092] S430: Issue a warning based on the vehicle slipping status on the current track.

[0093] Specifically, the vehicle runaway status may include a non-runaway status, a runaway warning status, and an already runaway status. Among them, 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 is parked safely on the current track 3; 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 near the first switch 6, and a relatively serious vehicle runaway phenomenon has occurred, and immediate measures need to be taken to brake the runaway vehicle. When the vehicle runaway state is the non-runaway state, the current vehicle parking state of track 3 is normal and no warning reminder is given; when the vehicle runaway state is the runaway warning state, a warning reminder can be issued to inform the staff to take warning measures for vehicle runaway; when the vehicle runaway state is the runaway state, the vehicle has completely runaway, so it is necessary to issue an alarm warning reminder to remind the staff to take emergency measures for vehicle runaway to prevent accidents caused by vehicle runaway. The warning reminder may include but is not limited to at least one of voice reminder, buzzer reminder, light reminder, etc., and this embodiment does not make specific limitations on this.

[0094] For example, the warning reminder may include a buzzer reminder and a light reminder, wherein the buzzer reminder may include intermittent buzzing and continuous buzzing, and the light reminder may include green light reminder, yellow light reminder, and red light reminder. When the vehicle is in the runaway warning state, an intermittent buzzer and a yellow light reminder may be issued to attract the attention of the operator, so that the operator can intervene in the runaway warning state and avoid the runaway situation. When the vehicle is in the runaway state, a continuous buzzer and a red light reminder may be issued to warn the operator to promptly eliminate the vehicle runaway situation and prevent the vehicle from causing an accident.

[0095] This embodiment issues warnings 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 slipping state of the current track according to the occupancy state of the first track circuit and the occupancy state of the second track circuit, the method includes:

[0097] Obtaining the occupancy status of the third track circuit and the occupancy status of the fourth track circuit in the next track respectively; wherein the setting interval of the third track circuit in the next track overlaps 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 switch;

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

[0099] Specifically, after determining the vehicle slippage status of the current track based on the occupancy status of the first and second track circuits, vehicle slippage monitoring can be performed on the next track. By separately obtaining the occupancy status of the third and fourth track circuits in the next track, and then determining the vehicle slippage status of the next track based on the occupancy status of the third and fourth track circuits, the system systematically and continuously monitors the vehicle slippage status of each track, ensuring that every 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 This is a flow chart of another method for monitoring a vehicle slipping provided by an embodiment of the present invention. Figure 6 The monitoring method of vehicle slipping is further explained. Figure 1 and Figure 6 The vehicle slipping monitoring method comprises the following steps:

[0101] S510: Obtain 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 the relief state, the operation of obtaining the parking device status of the next lane is executed.

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

[0105] Specifically, the upper computer 1 can obtain the parking brake status of the current track 3 from the parking brake control system. Multiple parking brakes are controlled in an integrated manner. When work needs to be done on the vehicle, the parking brake control system can simultaneously control multiple parking brakes to be in a braking state. 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 brake does not need to brake the vehicle, and the parking brake control system can simultaneously control multiple parking brakes to be in a relief state. Therefore, the parking device status obtained by the host computer 1 from the parking device control system can indicate whether the vehicle has a parking demand in the current track 3. If the parking device status is a relief state, indicating that the current track 3 needs to be open to traffic normally and no vehicle slippage monitoring is required, the parking device status of the next track is obtained, and then the parking device status of the next track is determined based on the parking device status of the next track to determine whether the next track needs to be monitored for vehicle slippage; if the parking device status is a braking state, indicating that the current track 3 needs to be parked and vehicle slippage monitoring is required, the occupation status of the first track circuit 4 and the occupation status of the second track circuit 5 in the current track 3 are obtained respectively, and the vehicle slippage status of the current track 3 is determined based on the occupation status of the first track circuit 4 and the occupation status of the second track circuit 5, so as to realize slippage monitoring of the vehicles parked in the current track 3. For example, the host computer 1 and the parking device control system can communicate with each other using an 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 obtaining the parking device status of the current track, and filters information about 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.

[0109] The determination module 620 is configured to determine the vehicle slipping state of the current track according to the occupancy state of the first track circuit and the occupancy state of the second track circuit.
