Before introducing the vehicle management method, the controller and the storage medium provided by the disclosure, application scenarios related to various embodiments of the disclosure are first described. The vehicle in the application scenario may be any vehicle running according to a preset track, for example: trains, subways, light rails, trams, etc., communication can be made between vehicles running on the preset track and the controller. When communication between the train and the controller is interrupted due to the failure of the train communication equipment, the running of the train is influenced, and meanwhile, the influence on other trains exists.
Fig. 1 is a flowchart illustrating a method of managing a vehicle according to an exemplary embodiment, as shown in fig. 1, applied to a controller, the method including:
step 101, in a case where it is determined that communication with the target vehicle is disconnected, first position information transmitted by the target vehicle for the last time is acquired.
And 102, controlling the aircraft to track the target vehicle according to the first position information and the identification information of the target vehicle so as to acquire the running information of the target vehicle, wherein the running information is used for indicating the running state of the target vehicle.
For example, the execution subject controller of the present disclosure may be, for example, a target controller (ObjectController, OC), where the controller needs to track the target vehicle if it determines that communication with the target vehicle is disconnected, and since the target vehicle immediately performs emergency braking after communication with the controller is interrupted, the target vehicle may eventually stop near a location indicated by the first location information, and thus may acquire the first location information that is transmitted by the target vehicle for the last time, and control the aircraft to track the target vehicle according to the first location information and the identification information of the target vehicle. The aircraft can acquire the running information of the target vehicle in real time. The driving information is used to indicate the driving state of the target vehicle, and may include, for example, second position information, speed information, driving direction information, and the like of the vehicle.
In some embodiments, a millimeter wave radar and camera assembly may be provided in an aircraft. The millimeter wave radar can acquire the relative speed of the target vehicle in real time, the camera can identify the target vehicle and the vehicle identification of the target vehicle, and the vehicle identification can be the vehicle number. Through the above radar combined sensor fusion algorithm, the flight detector can accurately identify and track the degraded train. The aircraft also comprises a processing unit and a communication unit, wherein the processing unit can process information acquired by the radar and the camera, and the communication unit can receive instructions sent by the controller and send acquired relevant information of the vehicle to the controller.
Step 103, obtaining the running information of the target vehicle sent by the aircraft, and determining the control section according to the running information.
And 104, sending a management and control indication message to other vehicles in communication with the controller, wherein the management and control indication message is used for indicating a management and control section so that the other vehicles can operate according to the management and control indication message.
For example, the controller may acquire travel information of the target vehicle acquired by the aircraft in real time, and determine the control section according to the travel information. In some embodiments, the running line may be divided into a plurality of track sections in advance, and after the running information of the target vehicle is obtained, the track section corresponding to the position of the vehicle indicated by the running information may be used as the management section. In other embodiments, the section between the head position of the target vehicle forward at a first preset distance and the rear position rearward at a second preset distance may be used as the management section.
Then, a control instruction message may be generated according to the control section, and the control instruction message may be sent to other vehicles that are in communication with the controller, that is, other vehicles that can normally communicate with the controller, to instruct the other vehicles to prohibit entry into the control section, so as to avoid collision between the other vehicles and the target vehicle. In some embodiments, the controller may further send the driving information of the target vehicle to other vehicles, so that the other vehicles control the vehicles to drive on the line according to the driving information of the target vehicle, thereby further ensuring the safety of the line operation. Meanwhile, after receiving the control indication message, other vehicles only need to control the vehicles to avoid the control section and still can run on the line outside the control section, so that the running efficiency of the line is improved.
In summary, in the case of determining that communication with the target vehicle is disconnected, the present disclosure firstly obtains first location information that is transmitted by the target vehicle for the last time, and according to the first location information and identification information of the target vehicle, controls the aircraft to track the target vehicle, so as to obtain driving information of the target vehicle through the aircraft, determines a control section according to the driving information, and then sends a control instruction message to other vehicles that communicate with the controller, so as to instruct the control section to the other vehicles. According to the method and the device, the target vehicle with communication interruption with the controller is tracked through the aircraft, the control section is determined according to the acquired running information, and the control section is indicated to other vehicles, so that other vehicles with normal communication can be prevented from colliding with the target vehicle under the condition that the communication interruption occurs to the target vehicle, the running safety of a line is ensured, the whole line where the target vehicle is located is not required to be blocked, and the running efficiency of the line is ensured.
In an application scenario, one implementation of step 102 may be:
And sending a tracking instruction to the aircraft, wherein the tracking instruction comprises the first position information, the identification information and the running direction of the target vehicle, so that the aircraft flies to the position corresponding to the first position information, and tracking the target vehicle according to the identification information and the running direction based on the position corresponding to the first position information so as to acquire the second position information of the target vehicle.
For example, since the target vehicle immediately makes an emergency brake after communication with the controller is interrupted, the target vehicle may stop near the position indicated by the first position information. The controller may send tracking instructions to the aircraft to control the aircraft to track the target vehicle. Wherein the tracking instruction includes first position information, identification information, and a traveling direction of the target vehicle. In some embodiments, after receiving the tracking instruction, the aircraft may parse the tracking instruction to obtain the first position information, the identification information and the driving direction of the target vehicle, and then fly to a position indicated by the first position information, and according to the identification information, detect the target vehicle by using a radar and a camera provided on the aircraft, and if the target vehicle is not detected, continue to fly along the driving direction of the target vehicle, and continue to detect the target vehicle until the target vehicle is detected. After the target vehicle is tracked, the traveling information of the target vehicle may be acquired.
After the target vehicle is braked suddenly, the operator can remotely control the target vehicle to travel to the parking area through the ATS system, and when the communication connection between the target vehicle and the ATS system is interrupted, the target vehicle is in a non-limited manual driving mode, and at this time, the operator can drive the target vehicle to travel to the parking area. In the running process of the target vehicle, the aircraft can continuously track the target vehicle, and send running information of the target vehicle acquired in real time to the controller, and then the controller sends the running information to other vehicles. Other vehicles may control the vehicle to travel according to the travel information of the target vehicle to avoid collision with the target vehicle.
Fig. 2 is a flowchart illustrating another vehicle management method according to an exemplary embodiment, and as shown in fig. 2, the driving information includes: second position information of the target vehicle. Step 103 may be implemented by the steps of:
step 1031, determining a track section corresponding to the second position information from the plurality of preset track sections.
Step 1032, using the track section corresponding to the second position information as the control section.
For example, the running line may be divided into a plurality of track sections in advance, and after the second position information is obtained, the track section corresponding to the second position information may be further determined. In some embodiments, the whole line may be divided into a plurality of track sections in advance, and each track section may have a length of 200-350 meters, for example, and the platform area and the switch area may be appropriately adjusted according to the station and switch positions. The status of the corresponding section of each track section is displayed and controlled for yard conditions, e.g., in extreme weather, operators may set the corresponding track section as a speed-limiting section to speed limit vehicles traveling within the designated track section, and in emergency conditions, e.g., such as conditions of a front stop collapse and a sudden fire, the corresponding section may be set as a blocking section to ensure that vehicles do not enter the hazardous area. In the present disclosure, the track section corresponding to the second position information may be set as a management section to instruct the other vehicle to stop driving into the track section to avoid colliding with the target vehicle.
FIG. 3 is a flowchart illustrating another method of managing a vehicle, according to an exemplary embodiment, as shown in FIG. 3, the method further comprising:
and 105, sending a tracking stopping instruction to the aircraft when the target vehicle and the controller resume communication, wherein the tracking stopping instruction is used for instructing the aircraft to stop tracking the target vehicle and fly to a designated area.
For example, if the target vehicle is detected to resume communication with the controller, it means that the controller can acquire the position information, the running speed, the running direction and other running information of the target vehicle in real time, without the need for the aircraft to track the target vehicle. A stop tracking instruction may be sent to the aircraft to instruct the aircraft to stop tracking the target vehicle and fly to the designated area. The designated area may be a preset waiting area, and the aircraft may charge in the waiting area to execute a next flight task.
Fig. 4 is a flowchart illustrating another vehicle management method according to an exemplary embodiment, and as shown in fig. 4, an aircraft includes a first aircraft and a second aircraft, and travel information includes first travel information and second travel information. The first aircraft is used for tracking the head of the target vehicle to acquire first driving information, and the second aircraft is used for tracking the tail of the target vehicle to acquire second driving information. Step 103 may also be implemented by:
step 1033, acquiring first traveling information and second traveling information.
Step 1034, determining the control section according to the first driving information and the second driving information.
In one application scenario, determining the control section according to the first travel information and the second travel information includes:
and determining a control section according to the head position of the target vehicle indicated by the first driving information and the tail position of the target vehicle indicated by the second driving information.
For example, considering that during tracking, if an aircraft fails, the aircraft needs to be reissued for re-tracking, the target vehicle is easily lost, or a large error is caused. And the vehicles can be tracked at the head and the tail of the vehicle respectively in consideration of the longer length of the vehicles running on certain lines. As shown in fig. 5, a first aircraft B and a second aircraft a may be dispatched simultaneously, and a target vehicle X may be tracked by identifying the head and tail, respectively. The first aircraft is used for tracking the headstock of the target vehicle to acquire first driving information, wherein the first driving information is the driving information of the vehicle acquired at the headstock of the target vehicle. The second aircraft is used for tracking the tail of the target vehicle to acquire second running information, wherein the second running information is the running information of the vehicle acquired at the head of the target vehicle.
In some embodiments, first travel information and second travel information may be acquired, and the management and control section is determined according to a head position of the target vehicle indicated by the first travel information and a tail position of the target vehicle indicated by the second travel information. In one implementation, a track section in which the target vehicle is located may be determined from among a plurality of track sections divided in advance according to the head position and the tail position, and the track section may be used as the management section. In another implementation manner, a section between the front position and the rear position at a first preset distance can be used as a control section, and the target detection range is changed along with the movement of the target vehicle, and the control section is dynamically changed. Therefore, after receiving the control indication message, other vehicles only need to control the vehicles to avoid the control section and still can run on the line outside the control section, so that the running efficiency of the line is improved.
Fig. 6 is a flowchart illustrating another vehicle management method according to an exemplary embodiment, as shown in fig. 6, the method further comprising:
and step 106, sending a management and control indication message to the ATS so that the ATS displays the management and control section.
By way of example, under the condition that communication between the target vehicle and the ATS is normal, the management and control indication message may be sent to the ATS, the ATS may parse the management and control indication message and display the management and control section on the working interface, so that the traffic dispatcher performs manual intervention and processing, and further, the security of line operation is ensured.
In summary, in the case of determining that communication with the target vehicle is disconnected, the present disclosure firstly obtains first location information that is transmitted by the target vehicle for the last time, and according to the first location information and identification information of the target vehicle, controls the aircraft to track the target vehicle, so as to obtain driving information of the target vehicle through the aircraft, determines a control section according to the driving information, and then sends a control instruction message to other vehicles that communicate with the controller, so as to instruct the control section to the other vehicles. According to the method and the device, the target vehicle with communication interruption with the controller is tracked through the aircraft, the control section is determined according to the acquired running information, and the control section is indicated to other vehicles, so that other vehicles with normal communication can be prevented from colliding with the target vehicle under the condition that the communication interruption occurs to the target vehicle, the running safety of a line is ensured, the whole line where the target vehicle is located is not required to be blocked, and the running efficiency of the line is ensured.
