In step S1024, obstacle information within the target area is monitored.

For example, the position of an obstacle on a track may be obtained by a differential positioning system.

For example, the location of obstacles on a rail yard may be marked with a map and Global Positioning System (GPS) and current location information of the vehicle provided. By combining the information, an optimal driving route of the road and railway dual-purpose deicing snowmobile is established, and obstacles are avoided.

For another example, an artificial intelligent algorithm can be used for planning a path according to known obstacle information and real-time data of a vehicle, so that the road and railway dual-purpose deicing snowmobile can automatically select an optimal route and adjust in real time to cope with a new obstacle.

In step S1026, the time when the switch in the target area is frozen and cannot be moved and the switch movement requirement when the subsequent train passes through the station track are evaluated.

For example, according to the current ambient temperature and the number of times of passing trains in a certain time on a certain switch, if the ambient temperature is lower and the number of trains passing the switch in a certain time is higher, the time required for the switch to be frozen is shorter, so that the switch should be preferentially subjected to ice and snow removal during scheduling.

In step S104, an ice and snow removal control command is generated according to the scene data, including:

step S1042, determining a walking track according to the fine map, the obstacle information and the priority of the switch to be processed, so that the road-railway dual-purpose deicing snowmobile walks on the walking track;

In step S1044, the first air blower 11, the second air blower 12 and the third air blower 13 are controlled to move according to the walking track and the position of the working object, so that the hot air covers at least part of the switches in the working object.

In step S1042, a walking track is determined according to the fine map, the obstacle information and the priority of the switch to be processed, and an optimal path is determined in consideration of the avoidance of the obstacle and the weight of the switch priority, so that the road-railway dual-purpose deicing snowmobile walks on the walking track.

For example, referring to fig. 5 and 7, the present embodiment adopts a satellite positioning system, a differential positioning system and a magnetic signature positioning system to position and schedule a road-railway dual-purpose deicing snowmobile so as to walk on a walking track.

The satellite positioning system can adopt a Beidou positioning navigation system. The Beidou positioning device is mounted on the highway and railway dual-purpose vehicle, and the Beidou positioning device can acquire satellite signals and calculate the accurate position of the vehicle. Meanwhile, a vehicle-mounted dispatching system is installed on the vehicle, and the system can receive Beidou positioning data and display the Beidou positioning data on a monitoring screen of a dispatching center.

Meanwhile, a differential positioning system is installed on the highway and railway dual-purpose vehicle, and the system can provide more accurate positioning data. The differential positioning corrects the position of the vehicle by receiving satellite signals through the base station and calculating errors, thereby improving the positioning accuracy.

And in a dispatching center, the position and dispatching of the road and railway dual-purpose deicing snowmobile are monitored and managed through a server. The server receives and processes the positioning data sent by the vehicle, so that the position and the state of the vehicle can be tracked in real time. And adopting a train dispatching system to conduct intelligent dispatching according to the positions and the demands of the road and railway dual-purpose deicing snow trucks. By way of example, the train dispatch system may be an existing railroad dispatch director information system (TDCS) or a decentralized autonomous dispatch centralized system (CTC).

In addition, the train dispatch system can be integrated with other data sources (such as weather forecast and traffic conditions) to make more accurate decisions.

In general, deicing and snow-removing operations are performed on the switch with the highest priority, and if there are switches on two sides of the switch with the highest priority, the road-railway dual-purpose deicing and snow truck can walk on the track where the switch with the highest priority is located, and the first air supply device 11, the second air supply device 12 and the third air supply device 13 are driven to move simultaneously so as to simultaneously convey hot air to the side-rail switch and the track switch where the switch is located, thereby improving the working efficiency.

When selecting a road-to-rail ice and snow removal vehicle, it is generally necessary to acquire a real-time position of the road-to-rail ice and snow removal vehicle, and select a vehicle closest to the vehicle and a suitable track to perform an ice and snow removal task.

For example, when there are a plurality of switches in the yard to remove ice and snow, the distance between the road and railway dual-purpose ice and snow removing vehicle and the target working area and the position of the train running normally in the target working area are considered comprehensively, for example, three switches in the yard to remove ice and snow are arranged, the road and railway dual-purpose ice and snow removing vehicle closest to the middle switch is selected to run on the middle track, and then the first air supply device 11, the second air supply device 12 and the third air supply device 13 are driven to move simultaneously so as to simultaneously supply hot air to the side-rail switch and the track switch where the side-rail switch is located, thereby improving the response speed and the working efficiency.

When there is a train running normally on the middle track, it is necessary to calculate the time t ₁ required for the train to run into the target area, and at the same time, it is necessary to calculate the time t ₂ required for the ice and snow removal of the road and railway ice and snow removal vehicle in the target area, if t ₂＜t₁, the optimal scheme can be selected, if t ₂＞t₁ is not adopted, at this time, the ice and snow removal operation can be performed after the train runs out of the target area, and if the condition allows, the train can run on the track spaced one track from the middle track, and only the first air supply device 11 or the second air supply device 12 is driven to supply hot air to the track switch beside the middle track.

The sensor may be a magnetic force sensor or other suitable sensor, and may detect according to the magnetic field characteristics of the magnetic tag. The sensor collects data of the positions of the road and railway dual-purpose deicing snowmobiles in real time, wherein the data can comprise the positions of magnetic labels, the states of turnouts and the like.

And analyzing the position of the road and railway dual-purpose deicing snowmobile and the state of the turnout by utilizing the collected data, designing a positioning and scheduling algorithm, and determining how to optimally schedule the road and railway dual-purpose deicing snowmobile so as to improve deicing and snow efficiency. According to the result of the algorithm, the train dispatching system can automatically send the road-railway dual-purpose deicing snowmobile to a specific position, dynamically adjust the road-railway dual-purpose deicing snowmobile according to the state of a turnout and the position of the road-railway dual-purpose deicing snowmobile, and simultaneously predict the optimal route of the road-railway dual-purpose deicing snowmobile through a machine learning algorithm and optimize dispatching so as to improve the working efficiency.

In step S1044, the first air blower 11, the second air blower 12 and the third air blower 13 are controlled to move according to the walking track and the position of the working object, respectively, so that the hot air covers at least part of the switch in the working object.

When the running track and the turnout on both sides of the running track are provided with the turnouts which need to remove ice and snow, the first air supply device 11, the second air supply device 12 and the third air supply device 13 can be controlled to move simultaneously so that the hot air covers all turnouts in the working object.

When the running track has no turnout for removing ice and snow, and one side or two sides of the running track have turnouts for removing ice and snow, the movement of the first air supply device 11 and the second air supply device 12 can be selectively controlled according to the requirement.

When the track and one side of the track need to remove ice and snow, the third air supply device 13 can be controlled to move so as to cover the track switch with hot air, and simultaneously, the first air supply device 11 or the second air supply device 12 can be selectively controlled to move according to the requirement so as to cover the track switch with hot air and the side track switch with hot air.
