Description

Technical Field

[0001] The present invention relates to the field of railway vehicle parking and anti-skidding, and in particular to a vehicle skidding monitoring method, device, equipment and storage medium. Background Art

[0002] During transportation operations at a railway hump yard, shunting vehicles must be marshaled on the tracks within the yard. Two to four parking devices are typically installed at the rear of the yard to stop these vehicles. Due to the influence of the parking devices themselves and external factors, parked vehicles can slip. In severe cases, these vehicles can run off the track, causing accidents such as head-on collisions, side collisions, and derailment, posing a significant safety hazard to railway transportation.

[0003] Currently, vehicle stoppers are commonly installed at the end of hump yards. Braking and release are controlled by a stopper control system, but this system does not monitor the effectiveness of the control, making it impossible to detect whether a vehicle is slipping while braked. According to the currently used stopper configuration, the last stopper does not participate in stopping a slipping vehicle and is only used to prevent vehicles from running off the track in exceptional circumstances. However, the current stopper section lacks detection devices, making it impossible to monitor in real time whether a vehicle parked on the track is slipping. Summary of the Invention

[0054] 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 slip 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 grating 4, a second grating 5, a third grating 6, a first switch 7 and a first parking device 8.

[0055] Specifically, 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 closest to the first switch 7 is the first parking device 8. The first grating 4 is located on the side of the current track 3 away from the first switch 7, the second grating 5 is located on the side of the current track 3 near the first switch 7, and the third grating 6 is located in the current track 3 and on the side of the second grating 5 near the first switch 7. The state acquisition device 2 is connected to the host computer 1, the first grating 4, the second grating 5, and the third grating 6, respectively. The connection between the state acquisition device 2 and the host computer 1 can be achieved based on a controller area network (CAN), a local interconnect network (LIN), or Ethernet. The state acquisition device 2 collects the occupancy status of the first grating 4, the second grating 5, and the third grating 6, and then transmits the occupancy status to the host computer 1 for analysis to achieve vehicle slippage monitoring.

[0056] like Figure 1 and Figure 2 As shown, the vehicle slipping monitoring method based on the above structure includes the following steps:

[0057] S110 , respectively obtaining the occupation status of the first grating, the occupation status of the second grating, and the occupation status of the third grating in the current track.

[0058] Among them, the first grating 4 is located on the side of the first parking device 8 in the current track 3 away from the first switch 7, the second grating 5 is located on the side of the first parking device 8 in the current track 3 close to the first switch 7, and the third grating 6 is located in the current track 3 and on the side of the second grating 5 close to the first switch 7.

[0059] 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 perform work on the vehicle, multiple parking devices are controlled simultaneously through their internal mechanical structures to generate braking force on the slipping vehicle, so that the vehicle can quickly slow down 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 8 is the last parking device passed by the slipping vehicle. The first grating 4, the second grating 5 and the third grating 6 are all independently set, and the occupation status of the first grating 4, the occupation status of the second grating 5 and the occupation status of the third grating 6 in the current track 3 are respectively obtained through the state acquisition device 2. Exemplarily, the state acquisition device 2 can be a safety relay, a PLC or an optocoupler acquisition module, which is not specifically limited in this embodiment.

[0060] S120 : Determine the vehicle slipping state of the current track according to the occupation state of the first light barrier, the occupation state of the second light barrier, and the occupation state of the third light barrier.

[0061] Specifically, in the railway hump yard, the first parking device 8 generally does not participate in the braking work for parking the vehicle, that is, no vehicle is parked at the first parking device 8. Therefore, when the vehicle does not slip away, the first grating 4, the second grating 5 and the third grating 6 are not occupied; and when the parked vehicle slips away along the extension direction X of the current track 3 toward the first switch 7, the slipping vehicle will occupy the first grating 4, the second grating 5 or the third grating 6. The upper computer 1 determines the vehicle slipping state of the current track 3 based on the occupied state of the first grating 4, the occupied state of the second grating 5 and the occupied state of the third grating 6 obtained by the state acquisition device 2. If the occupied state of the first grating 4, the occupied state of the second grating 5 and the occupied state of the third grating 6 are all idle states, then the vehicle slipping state of the current track 3 is determined to be a non-slipping state; if the occupied state of the first grating 4, the occupied state of the second grating 5 or the occupied state of the third grating 6 is an occupied state, then the vehicle slipping state of the current track 3 is determined to be a slipping state.

[0062] This embodiment obtains the occupancy status of the first grating, the occupancy status of the second grating, and the occupancy status of the third grating respectively, and determines the vehicle runaway status of the current track based on the occupancy status of the first grating, the occupancy status of the second grating, and the occupancy status of the third grating, so as to realize real-time monitoring of whether the vehicles parked in the current track have runaway, ensure the timeliness of vehicle runaway monitoring, enable station attendants to promptly understand the position of the vehicles 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.

[0063] 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 the figure explains how to determine the vehicle slipping state of the current track based on the occupation state of the first grating, the occupation state of the second grating and the occupation state of the third grating. Figure 1 and Figure 3 As shown, the vehicle slipping monitoring method includes the following steps:

[0064] S210 , respectively obtaining the occupation status of the first grating, the occupation status of the second grating, and the occupation status of the third grating in the current track.

[0065] Among them, the first grating 4 is located on the side of the first parking device 8 in the current track 3 away from the first switch 7, the second grating 5 is located on the side of the first parking device 8 in the current track 3 close to the first switch 7, and the third grating 6 is located in the current track 3 and on the side of the second grating 5 close to the first switch 7.

[0066] Optionally, along the extension direction X of the current track 3, the first grating 4 is arranged at the entrance of the first parking device 8 away from the first switch 7, the second grating 5 is separated from the exit of the first parking device 8 close to the first switch 7 by a first length, and the third grating 6 is separated from the exit of the first parking device 8 close to the first switch 7 by a second length; wherein the second length is greater than the first length.

[0067] Specifically, when a parked vehicle slips along the extension direction X of the current track 3, the occupancy status of the first light barrier 4 at the entrance of the first parking device 8 can indicate whether a vehicle is occupying the first parking device 8; the occupancy status of the second light barrier 5 at a first distance from the exit of the first parking device 8 can indicate whether part of the vehicle body has begun to exceed the control range of the first parking device 8; and the occupancy status of the third light barrier 6 at a second distance from the exit of the first parking device 8 can indicate whether the entire vehicle has exceeded the control range of the first parking device 8. This configuration allows station staff to understand the location of slipping vehicles in detail, improving the accuracy of vehicle slip monitoring.

[0068] For example, along the extension direction X of the current track 3, the second grating 5 can be set at 8m-10m away from the first parking device 8 near the exit of the first switch 7, and the third grating 6 can be set at 16m-18m away from the first parking device 8 near the exit of the first switch 7. This embodiment does not make specific limitations on this.

[0069] S220: When the occupation state of the first grating is the occupied state, determine that the vehicle runaway state of the current track is the runaway warning state.

[0070] Specifically, when a parked vehicle slips along the extension direction X of the current track 3 toward the first switch 7, the parked vehicle will move from other parking devices on the current track 3 to the first parking device 8. At this time, the vehicle will first occupy the first grating 4, and the occupancy state of the first grating 4 will change from the initial idle state to the occupied state. At this time, the first grating 4 obtained by the status acquisition device 2 is in the occupied state, indicating that at least part of the main body of the vehicle is about to slip to the first stop 8, and then the status acquisition device 2 transmits the information that the first grating 4 is in the occupied state to the host computer 1. Since the first grating 4 is located on the side of the first stop 8 away from the first switch 7, the slipping vehicle at this time is still a certain distance away from the first stop 8, and there is still a certain time interval for the slipping vehicle to move to the first stop 8. 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 grating 4. The station staff can perform additional braking operations on the first stop 8 according to the slipping warning state to brake the slipping vehicle through the first stop 8 to ensure driving safety and prevent accidents.

[0071] Since the runaway vehicle has not reached the first parking device 8 in the runaway alert state, for example, the staff can brake the runaway vehicle through the first parking device 8 or open a safety line at the first switch 7 when determining that the vehicle's runaway state is the runaway alert state, so as to stop the vehicle from continuing to run away and avoid safety accidents caused by the vehicle running away.

[0072] S230: When the occupation state of the second grating is the occupied state, it is determined that the vehicle runaway state of the current track is the runaway warning state.

[0073] Specifically, when the parked vehicle arrives at the first parking device 8 and continues to slip along the extension direction X of the current track 3 toward the first switch 7, the vehicle will occupy the second grating 5, and the occupation state of the second grating 5 will change from the initial idle state to the occupied state. At this time, the second grating 5 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 out of the first parking device 8 (for example, the front wheels of the slipping vehicle have exceeded the control range of the first parking device 8). Then, the state acquisition device 2 transmits the information that the second grating 5 is in the occupied state to the host computer 1. Since the second grating 5 is located on the side of the first parking device 8 close to the first switch 7, the slipping vehicle at this time is still a certain distance away from the first switch 7, and there is still a certain time interval for the slipping vehicle to rush out of the first switch 7. The host computer 1 can determine the vehicle slipping state of the current track 3 as the slipping warning state based on the occupied state of the second grating 5. The 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.

[0074] Since at least part of the main body of the slipping vehicle is still located at the first parking device 8 in the runaway warning state, for example, when the staff determines that the vehicle's runaway state is the runaway warning state, they can brake the main body of the vehicle still located at the first parking device 8 through the first parking device 8 or open a safety line at the first switch 7 to stop the vehicle from continuing to slip away and avoid safety accidents caused by the vehicle slipping away.

[0075] S240: When the occupation state of the third light barrier is the occupied state, determine that the vehicle slipping state of the current track is the slipped state.

[0076] Specifically, when the vehicle that has run away passes the second grating 5 along the extension direction X of the current track 3 and continues to run away towards the first switch 7, the vehicle that has run away will move to the third grating 6 on the current track 3. At this time, the vehicle will occupy the third grating 6, and the occupancy state of the third grating 6 will change from the initial idle state to the occupied state. At this time, the third grating 6 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 third grating 6, and then the state acquisition device 2 transmits the information that the third grating 6 is in the occupied state to the host computer 1. Since the third grating 6 is located between the second grating 5 and the first switch 7, the slipping vehicle at this time is closer to the first switch 7, 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 third grating 6. 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.

[0077] Since at least part of the main body of the vehicle is located at the third grating 6 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 devices (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.

[0078] In this embodiment, when the first grating is in the occupied state, the vehicle slipping state of the current track is determined to be in the slipping alert state; when the second grating is in the occupied state, the vehicle slipping state of the current track is determined to be in the slipping warning state; when the third grating is in the occupied state, the vehicle slipping state of the current track is determined to be in the slipped state, so that the staff can quickly understand the slipping situation of the vehicle, can take corresponding countermeasures for different slipping situations, reasonably optimize the resource allocation in the countermeasure plan, and improve the monitoring accuracy of vehicle slipping and the safety of station operation.

[0079] 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 grating, the occupation status of the second grating and the occupation status of the third grating in the current track respectively. Figure 1 As shown, the first grating 4 includes a first optical signal transmitting unit 41 and a first optical signal receiving unit 42, and the first optical signal receiving unit 42 is electrically connected to the first electrical signal collecting unit; the first optical signal transmitting unit 41 is used to transmit the first optical signal, and the first optical signal receiving unit 42 is used to receive the first optical signal and output the first electrical signal to the first electrical signal collecting unit according to the received amount of the first optical signal;

[0080] The second grating 5 includes a second optical signal transmitting unit 51 and a second optical signal receiving unit 52, and the second optical signal receiving unit 52 is electrically connected to the second electrical signal collecting unit; the second optical signal transmitting unit 51 is used to transmit the second optical signal, and the second optical signal receiving unit 52 is used to receive the second optical signal and output the second electrical signal to the second electrical signal collecting unit according to the received amount of the second optical signal;

[0081] The third grating 6 includes a third optical signal transmitting unit 61 and a third optical signal receiving unit 62, and the third optical signal receiving unit 62 is electrically connected to the third electrical signal acquisition unit; the third optical signal transmitting unit 61 is used to transmit the third optical signal, and the third optical signal receiving unit 62 is used to receive the third optical signal and output the third electrical signal to the third electrical signal acquisition unit according to the received amount of the third optical signal.

[0082] Specifically, the state acquisition device 2 may include a first electrical signal acquisition unit (not shown in the figure), a second electrical signal acquisition unit (not shown in the figure), and a third electrical signal acquisition unit (not shown in the figure). The first electrical signal acquisition unit is respectively connected to the first optical signal receiving unit 42 and the host computer 1, the second electrical signal acquisition unit is respectively connected to the second optical signal receiving unit 52 and the host computer 1, and the third electrical signal acquisition unit is respectively connected to the third optical signal receiving unit 62 and the host computer 1. The first grating 4 includes a first optical signal transmitting unit 41 and a first optical signal receiving unit 42, which are distributed on both sides of the extension direction X of the current track 3. The first optical signal transmitting unit 41 converts the electrical signal supplied by the power supply into a first optical signal and transmits it to the first optical signal receiving unit 42. After receiving the first optical signal, the first optical signal receiving unit 42 converts the first optical signal into a current of corresponding magnitude according to the amount of the first optical signal received, and then outputs the current as a first electrical signal to the first electrical signal acquisition unit, thereby enabling the first electrical signal acquisition unit to collect the first electrical signal of the first grating 4. The second grating 5 includes a second optical signal transmitting unit 51 and a second optical signal receiving unit 52, which are distributed on both sides of the extension direction X of the current track 3. The second optical signal transmitting unit 51 converts the electrical signal supplied by the power supply into a second optical signal and transmits it to the second optical signal receiving unit 52; after receiving the second optical signal, the second optical signal receiving unit 52 converts the second optical signal into a current of corresponding size according to the received amount of the second optical signal, and then outputs the current as a second electrical signal to the second electrical signal acquisition unit, so that the second electrical signal acquisition unit can collect the second electrical signal of the second grating 4. The third grating 6 includes a third optical signal transmitting unit 61 and a third optical signal receiving unit 62, which are distributed on both sides of the extension direction X of the current track 3. The third optical signal transmitting unit 61 converts the electrical signal supplied by the power supply into a third optical signal and transmits it to the third optical signal receiving unit 62; after receiving the third optical signal, the third optical signal receiving unit 62 converts the third optical signal into a current of corresponding magnitude according to the received amount of the third optical signal, and then outputs the current as a third electrical signal to the third electrical signal acquisition unit, thereby enabling the third electrical signal acquisition unit to collect the third electrical signal of the third grating 4.

[0083] like Figure 1 and Figure 4 As shown, the vehicle slipping monitoring method includes the following steps:

[0084] S310: Acquire the collection status of the first electrical signal by the first electrical signal collection unit, and determine the occupied state of the first grating as occupied when the first electrical signal collection unit does not collect the first electrical signal.

[0085] Specifically, the state acquisition device 2 may include a first electrical signal acquisition unit (not shown in the figure), which may be connected to the first optical signal receiving unit 42. The first grating 4, the second grating 5, and the third grating 6 are independently provided. When the occupancy state of the first grating 4 is different, the first electrical signal collected by the first electrical signal acquisition unit is different. Therefore, the first electrical signal of the first grating 4 collected at a certain moment can represent the occupancy state of the first grating 4 at that moment. The first electrical signal of the first grating 4 is collected by the first electrical signal acquisition unit to determine the occupancy state of the first grating 4 at that moment based on the first electrical signal.

[0086] Furthermore, when the first grating 4 is not occupied by a escaping vehicle, the first grating 4 is in an idle state, and the first optical signal emitted by the first optical signal transmitting unit 41 can be completely received by the first optical signal receiving unit 42, and converted into a rated current of corresponding size by the first optical signal receiving unit 42 to flow to the first electrical signal acquisition unit, and then the first electrical signal of the first grating 4 can be collected by the first electrical signal acquisition unit; when the first grating 4 is occupied by a escaping vehicle, since the first optical signal transmitting unit 41 and the first optical signal receiving unit 42 are located on both sides of the current track 3, the first optical signal emitted by the first optical signal transmitting unit 41 will be blocked by the escaping vehicle, resulting in the first optical signal receiving unit 42 being unable to receive the complete first optical signal, and thus being unable to generate the rated current, thereby making it impossible for the first electrical signal acquisition unit to collect the first electrical signal. If the first electrical signal acquisition unit can collect the first electrical signal, it indicates that no vehicle blocks the propagation of the first optical signal, and the occupancy state of the first grating 4 is determined to be an idle state; if the first electrical signal acquisition unit cannot collect the first electrical signal, it indicates that at least part of the main body of the vehicle has moved to the first grating 4, causing the escaping vehicle to block the propagation of the first optical signal, and the occupancy state of the first grating 4 is determined to be an occupied state.

[0087] For example, when the vehicle parked on the current track 3 does not slip, there is no vehicle between the first optical signal transmitting unit 41 and the first optical signal receiving unit 42, and the first optical signal emitted by the first optical signal transmitting unit 41 can be completely received by the first optical signal receiving unit 42, and converted by the first optical signal receiving unit 42 into a rated current of corresponding magnitude to flow to the first relay in the first electrical signal acquisition unit, so that the first relay is energized and drives the contact to be attracted, connecting the first electrical signal acquisition unit and the first grating 4, so that the first electrical signal acquisition unit can collect the first electrical signal of the first grating 4, and determine that the first grating 4 is at this time. In idle state; when the first grating 4 is occupied by a slipping vehicle, the first light signal emitted by the first light signal transmitting unit 41 will be blocked by the slipping vehicle, resulting in the first light signal receiving unit 42 being unable to receive the complete first light signal, and thus being unable to generate rated current, resulting in no current or a small current flowing to the first relay of the first electric signal acquisition unit, causing the first relay to lose current and lose magnetism or insufficient magnetism, and driving the contact to fall, disconnecting the first electric signal acquisition unit from the first grating 4, and the first electric signal acquisition unit being unable to collect the first electric signal of the first grating 4, thereby determining that the first grating 4 is in occupied state at this time. Whether the first electric signal acquisition unit collects the first electric signal is used to determine whether the first grating 4 is occupied by a vehicle.

[0088] S320: Acquire the collection status of the second electrical signal by the second electrical signal collection unit, and when the second electrical signal collection unit does not collect the second electrical signal, determine the occupation state of the second grating as occupied.

[0089] Specifically, the state acquisition device 2 may include a second electrical signal acquisition unit (not shown in the figure), which may be connected to the second optical signal receiving unit 52. The first grating 4, the second grating 5, and the third grating 6 are independently provided. When the occupancy state of the second grating 5 is different, the second electrical signal collected by the second electrical signal acquisition unit is different. Therefore, the second electrical signal of the second grating 5 collected at a certain moment can represent the occupancy state of the second grating 5 at that moment. The second electrical signal of the second grating 5 is collected by the second electrical signal acquisition unit to determine the occupancy state of the second grating 5 at that moment based on the second electrical signal.

[0090] Furthermore, when the second grating 5 is not occupied by a escaping vehicle, the second grating 5 is in an idle state, and the second optical signal emitted by the second optical signal transmitting unit 51 can be completely received by the second optical signal receiving unit 52, and converted into a rated current of corresponding size by the second optical signal receiving unit 52 to flow to the second electrical signal acquisition unit, and then the second electrical signal of the second grating 5 can be collected by the second electrical signal acquisition unit; when the second grating 5 is occupied by a escaping vehicle, since the second optical signal transmitting unit 51 and the second optical signal receiving unit 52 are located on both sides of the current track 3, the second optical signal emitted by the second optical signal transmitting unit 51 will be blocked by the escaping vehicle, resulting in the second optical signal receiving unit 52 being unable to receive the complete second optical signal, and thus unable to generate the rated current, thereby making it impossible for the second electrical signal acquisition unit to collect the second electrical signal. If the second electrical signal acquisition unit can collect the second electrical signal, it indicates that no vehicle blocks the propagation of the second optical signal, and the occupancy state of the second grating 5 is determined to be an idle state; if the second electrical signal acquisition unit cannot collect the second electrical signal, it indicates that at least part of the main body of the vehicle has moved to the second grating 5, causing the escaping vehicle to block the propagation of the second optical signal, and the occupancy state of the second grating 5 is determined to be an occupied state.

[0091] For example, when the vehicle parked on the current track 3 does not slip, there is no vehicle between the second optical signal transmitting unit 51 and the second optical signal receiving unit 52, and the second optical signal emitted by the second optical signal transmitting unit 51 can be completely received by the second optical signal receiving unit 52, and converted by the second optical signal receiving unit 52 into a rated current of corresponding magnitude to flow to the second relay in the second electric signal acquisition unit, so that the second relay is energized and drives the contact to be attracted, connecting the second electric signal acquisition unit and the second grating 5, so that the second electric signal acquisition unit can collect the second electric signal of the second grating 5, and determine that the second grating 5 is at this time. In idle state; when the second grating 5 is occupied by a slipping vehicle, the second optical signal emitted by the second optical signal transmitting unit 51 will be blocked by the slipping vehicle, resulting in the second optical signal receiving unit 52 being unable to receive the complete second optical signal, and thus being unable to generate rated current, resulting in no current or a small current flowing to the second relay of the second electrical signal acquisition unit, causing the second relay to lose current and lose magnetism or insufficient magnetism, and driving the contact to fall, disconnecting the second electrical signal acquisition unit from the second grating 5. The second electrical signal acquisition unit is unable to collect the second electrical signal of the second grating 5, thereby determining that the second grating 5 is in occupied state at this time. Whether the second electrical signal acquisition unit collects the second electrical signal is used to determine whether the second grating 5 is occupied by a vehicle.

[0092] S330: Acquire the collection status of the third electrical signal by the third electrical signal collection unit, and when the third electrical signal collection unit does not collect the third electrical signal, determine the occupied state of the third grating as occupied.

[0093] Specifically, the state acquisition device 2 may include a third electrical signal acquisition unit (not shown in the figure), which may be connected to the third optical signal receiving unit 62. The first grating 4, the second grating 5, and the third grating 6 are independently provided. When the occupancy state of the third grating 6 is different, the third electrical signal collected by the third electrical signal acquisition unit is different. Therefore, the third electrical signal of the third grating 6 collected at a certain moment can represent the occupancy state of the third grating 6 at that moment. The third electrical signal of the third grating 6 is collected by the third electrical signal acquisition unit to determine the occupancy state of the third grating 6 at that moment based on the third electrical signal.

[0094] Furthermore, when the third grating 6 is not occupied by a escaping vehicle, the third grating 6 is in an idle state, and the third optical signal emitted by the third optical signal transmitting unit 61 can be completely received by the third optical signal receiving unit 62, and converted into a rated current of corresponding size by the third optical signal receiving unit 62 to flow to the third electrical signal acquisition unit, and then the third electrical signal of the third grating 6 can be collected by the third electrical signal acquisition unit; when the third grating 6 is occupied by a escaping vehicle, since the third optical signal transmitting unit 61 and the third optical signal receiving unit 62 are located on both sides of the current track 3, the third optical signal emitted by the third optical signal transmitting unit 61 will be blocked by the escaping vehicle, resulting in the third optical signal receiving unit 62 being unable to receive the complete third optical signal, and thus unable to generate the rated current, thereby making it impossible for the third electrical signal acquisition unit to collect the third electrical signal. If the third electrical signal acquisition unit can collect the third electrical signal, it indicates that no vehicle blocks the propagation of the third optical signal, and the occupancy state of the third grating 6 is determined to be an idle state; if the third electrical signal acquisition unit cannot collect the third electrical signal, it indicates that at least part of the main body of the vehicle has moved to the third grating 6, causing the escaping vehicle to block the propagation of the third optical signal, and the occupancy state of the third grating 6 is determined to be an occupied state.

[0095] For example, when the vehicle parked in the current track 3 does not slip, there is no vehicle between the third optical signal transmitting unit 61 and the third optical signal receiving unit 62, and the third optical signal emitted by the third optical signal transmitting unit 61 can be completely received by the third optical signal receiving unit 62, and converted by the third optical signal receiving unit 62 into a rated current of corresponding magnitude to flow to the third relay in the third electrical signal acquisition unit, so that the third relay is energized and drives the contact to be attracted, connecting the third electrical signal acquisition unit and the third grating 6, so that the third electrical signal acquisition unit can collect the third electrical signal of the third grating 6, and determine that the third grating 6 is at this time. In an idle state; when the third grating 6 is occupied by a slipping vehicle, the third optical signal emitted by the third optical signal transmitting unit 61 will be blocked by the slipping vehicle, resulting in the third optical signal receiving unit 62 being unable to receive the complete third optical signal, and thus being unable to generate the rated current, resulting in no current or a small current flowing to the third relay of the third electrical signal acquisition unit, causing the third relay to lose current and lose magnetism or become insufficiently magnetic, and driving the contact to fall, disconnecting the third electrical signal acquisition unit from the third grating 6. The third electrical signal acquisition unit is unable to collect the third electrical signal of the third grating 6, thereby determining that the third grating 6 is in an occupied state at this time. Whether the third electrical signal acquisition unit collects the third electrical signal is used to determine whether the third grating 6 is occupied by a vehicle.

[0096] S340: Determine the vehicle slipping state of the current track according to the occupation state of the first light barrier, the occupation state of the second light barrier, and the occupation state of the third light barrier.

[0097] This embodiment is configured such that if the first acquisition unit fails to acquire the first electrical signal, the occupancy state of the first grating is determined to be an occupied state; if the second acquisition unit fails to acquire the second electrical signal, the occupancy state of the second grating is determined to be an occupied state; if the third acquisition unit fails to acquire the third electrical signal, the occupancy state of the third grating is determined to be an occupied state, so as to achieve independent acquisition of the occupancy states of the first grating, the second grating and the third grating, respectively, thereby improving the accuracy of vehicle runaway monitoring and avoiding the possibility of false detection and missed detection of vehicle runaway.

[0098] Optionally, the monitoring method further includes:

[0099] The emission heights and emission densities of the first light signal, the second light signal, and the third light signal are adjusted according to the vehicle type.

[0100] Specifically, the emission height and emission density of the first light signal, the second light signal, and the third light signal can be adjusted according to the type of vehicle currently parked on the track to improve the flexibility and accuracy of runaway monitoring. For example, when the vehicle currently parked on the track is a small vehicle, due to its low body, the emission height of the first light signal, the second light signal, and the third light signal should be appropriately lowered to ensure that the light beam coverage is concentrated in front of the vehicle and on both sides. At the same time, the emission density can be relatively increased to improve detection accuracy and response speed. When the vehicle currently parked on the track is a large truck, due to its high body and large size, the emission height of the first light signal, the second light signal, and the third light signal needs to be increased to ensure that the light beam can cover a wider range. At the same time, the emission density can be appropriately reduced to optimize energy consumption and avoid excessive false alarms.

[0101] 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:

[0102] S410 , respectively obtaining the occupation status of the first grating, the occupation status of the second grating, and the occupation status of the third grating in the current track.

[0103] Among them, the first grating 4 is located on the side of the first parking device 8 in the current track 3 away from the first switch 7, the second grating 5 is located on the side of the first parking device 8 in the current track 3 close to the first switch 7, and the third grating 6 is located in the current track 3 and on the side of the second grating 5 close to the first switch 7.

[0104] S420: Determine the vehicle slipping state of the current track according to the occupation state of the first light barrier, the occupation state of the second light barrier, and the occupation state of the third light barrier.

[0105] S430: Issue a warning based on the vehicle slipping status of the current track.

[0106] Specifically, the vehicle runaway state may include a non-runaway state, a runaway warning state, a runaway warning state and a runaway state, wherein the non-runaway state may be that the vehicle is parked on the current track 3 and has not moved to the first grating 4, and the vehicle on the current track 3 is parked safely; the runaway warning state may be that the vehicle moves to the section between the first grating 4 and the second grating 5, indicating that the vehicle has signs of runaway and staff are required to prevent the vehicle from running away; the runaway warning state may be that the vehicle moves to the section between the second grating 5 and the third grating 6, indicating that runaway has begun to occur, although it has not yet reached the level of complete runaway, but it needs to attract the attention of staff; the runaway state may be that the vehicle moves to the section between the third grating 6 and the first switch 7, and a more 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 issued; when the vehicle runaway state is the runaway warning state, a warning reminder can be issued to inform the staff that the vehicle may run away and take timely prevention measures; 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 the vehicle runaway; when the vehicle runaway state is the runaway state, the vehicle has completely run away, so it is necessary to issue an alarm warning reminder to remind the staff to take emergency measures for the vehicle runaway to prevent the vehicle from running away and causing an accident. 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 specific limitations on this.

[0107] 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's runaway state is the runaway alert state, a low-frequency intermittent buzzer sound and a purple light reminder may be emitted to inform the staff that the vehicle may run away and to prevent the vehicle from running away in time; when the vehicle's runaway state is the runaway warning state, a high-frequency intermittent buzzer sound and a yellow light reminder may be emitted to attract the attention of the staff, to intervene in the vehicle's runaway warning state, and to avoid the occurrence of a runaway situation; when the vehicle's runaway state is the already runaway state, a continuous buzzer sound and a red light reminder may be emitted to warn the operator to eliminate the vehicle's runaway situation in time to prevent the vehicle from running away and causing an accident.

[0108] 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.

[0109] Optionally, after determining the vehicle slipping state of the current track according to the occupation state of the first grating, the occupation state of the second grating, and the occupation state of the third grating, the method further includes:

[0110] Obtaining the occupancy status of the fourth grating, the fifth grating, and the sixth grating in the next track, respectively; wherein the fourth grating is located on the side of the second parking device in the next track away from the second switch, the fifth grating is located on the side of the second parking device in the next track close to the second switch, and the sixth grating is located in the next track and on the side of the fifth grating close to the second switch;

[0111] The vehicle slipping state of the next lane is determined according to the occupied state of the fourth light barrier, the occupied state of the fifth light barrier, and the occupied state of the sixth light barrier.

[0112] Specifically, after determining the vehicle slippage status of the current track based on the occupancy status of the first, second, and third light barriers, vehicle slippage monitoring can be performed on the next track. By respectively obtaining the occupancy status of the fourth, fifth, and sixth light barriers in the next track, and then determining the vehicle slippage status of the next track based on the occupancy status of the fourth, fifth, and sixth light barriers, the vehicle slippage status of each track is systematically and continuously monitored, 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.

[0113] 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:

[0114] S510: Obtain the parking device status of the current track.

[0115] S520: If the parking device is in the braking state, the operation of respectively obtaining the occupation status of the first grating, the occupation status of the second grating, and the occupation status of the third grating in the current track is performed on the current track.

[0116] S530: If the parking device status is the relief state, the operation of obtaining the parking device status of the next lane is executed.

[0117] S540: Determine the vehicle slipping state of the current track according to the occupation state of the first light barrier, the occupation state of the second light barrier, and the occupation state of the third light barrier.

[0118] 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 represent whether the vehicle has a parking demand in the current lane 3. If the parking device status is in the relief state, indicating that the current lane 3 needs to be open to traffic normally and no vehicle slippage monitoring is required, the parking device status of the next lane is obtained, and then the parking device status of the next lane is determined based on the parking device status of the next lane. If the parking device status is in the braking state, indicating that the current lane 3 needs to be parked and vehicle slippage monitoring is required, the occupation status of the first grating 4, the occupation status of the second grating 5, and the occupation status of the third grating 6 in the current lane 3 are respectively obtained, and the vehicle slippage status of the current lane 3 is determined based on the occupation status of the first grating 4, the occupation status of the second grating 5, and the occupation status of the third grating 6, thereby realizing slippage monitoring of the vehicles parked in the current lane 3. For example, the host computer 1 and the parking device control system can communicate with each other using an RS232 or Ethernet interface.

[0119] 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 the information of vehicles occupying the first grating, the second grating and the third grating under normal traffic conditions, thereby improving the efficiency and accuracy of vehicle runaway monitoring.

[0120] Based on the same inventive concept, Figure 7 FIG. 1 is a schematic structural diagram of a vehicle slipping monitoring device provided by an embodiment of the present invention, such as Figure 7 As shown, the vehicle slipping monitoring device includes: an acquisition module 610 and a determination module 620;

[0121] Acquisition module 610 is configured to respectively acquire the occupancy status of a first grating, a second grating, and a third grating in the current track; wherein the first grating is located on the side of the first stopper in the current track away from the first switch, the second grating is located on the side of the first stopper in the current track close to the first switch, and the third grating is located in the current track and on the side of the second grating close to the first switch;

[0122] The determination module 620 is used to determine the vehicle slipping state of the current track according to the occupation state of the first grating, the occupation state of the second grating and the occupation state of the third grating.

[0123] The vehicle runaway monitoring device provided in the embodiment of the present invention can execute the vehicle runaway monitoring method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the execution method.
