[0041] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0042] Figure 1 is a schematic diagram of the structure of a transportation system provided by an embodiment of the present invention, such as Figure 1 As shown, the system 100 includes a transport vehicle 1, a power supply device 2, a power extraction device 3, a power storage device 4 and a controller (not shown in the figure).

[0043] The power storage device 4 and the power extraction device 3 are arranged on the transport vehicle 1;

[0044] The power storage device 4 is used to provide electric energy to the transport vehicle 1;

[0045] The power supply device 2 is used to provide electrical energy;

[0046] The power taking device 3 is used to obtain electric energy from the power supply device 2 and transmit the obtained electric energy to the power storage device 4 or the transport vehicle 1;

[0047] The controller is used to control the power storage device 4 or the power extraction device 3 to provide electric energy for the transport vehicle 1 .

[0048] In this embodiment, when the transport vehicle 1 is moving along the road, it can obtain electric energy from the power supply device 2 through the power taking device 3, or it can obtain electric energy from the power storage device 4. Specifically, the controller selects the power storage device 4 or the power taking device 3 to provide electric energy for the transport vehicle 1 according to the actual transportation situation. For example, when the transport vehicle 1 is moving on a regular road section, the controller controls the power taking device 3 to provide electric energy for the transport vehicle 1; when the transport vehicle 1 is moving on a special road section and the power taking device 3 cannot be used for power supply, the controller can control the power storage device 4 to supply power to the transport vehicle 1, so that the transport vehicle 1 can transport goods on any road section, thereby improving the efficiency of transportation. At the same time, there is no need to rebuild the road section, which greatly reduces the transportation cost. Among them, the power supply device is arranged continuously or intermittently along the driving route of the transport vehicle. In the area where the power supply device is continuously arranged, the power supply device can realize power supply when the transport vehicle is running, or power supply when the transport vehicle is stationary.

[0049] Among them, if the power supply device 2 is a busbar power supply device laid on the road where the transport vehicle 1 travels, the power supply device 3 is a collector. The busbar power supply device is a device that uses the busbar to supply power to electrical equipment. The busbar power supply device includes a power supply cable, a leakage protection circuit, and a hard-line emergency stop control circuit. The collector can be a double-headed collector. After the transport vehicle 1 takes power from the busbar, an incoming line reactor is added.

[0050] If the power supply device 2 is a contactless power supply device laid on the road on which the transport vehicle 1 is traveling, the power collection device 3 is a pickup device, and the contactless power supply device includes a power supply cable. The contactless power supply device is a device that supplies power to electrical equipment by picking up the current generated by the magnetic field generated by the power supply cable pre-buried underground in real time through the pickup device.

[0051] In this embodiment, the power storage device 4 can also be charged through the power taking device 3, so that the transport vehicle 1 can control the charging of the power storage device 4 while transporting goods, without the need to go to a charging point for charging. The saved charging time can be used to transport goods, thereby improving transportation efficiency.

[0052] The transport system 100 may further include a host computer server, and the transport vehicle 1, the controller and the host computer server are connected to each other in communication to achieve information exchange, for example, by wireless communication. The power storage device 4 may be a super capacitor group, a battery group or other types of storage devices.

[0053] Optional, such as Figure 1 The transport system 100 shown also includes a track 5 and a ground device connected to the track; the track is used to guide the transport vehicle 1 to travel; and the ground device is used to adjust the travel direction, track height or travel route of the transport vehicle 1.

[0054] In this embodiment, when the transport system 100 includes a track 5, if the transport vehicle 1 needs to turn, replace the running track 5, or change the height of the running track, adjustments will be made through the ground device. The ground device can be arranged at the intersection of several running tracks 5. The track 5 can be a steel rail. The power supply cable or other fixed power supply components of the power supply device can be laid along the line of the steel rail.

[0055] Of course, the transport vehicle can also travel on a trackless road to transport goods. The trackless road can be arranged with guidance, navigation systems and other related facilities to guide the travel route for the transport vehicle 1. The transport vehicle traveling on the trackless road can choose a wheeled transport vehicle.

[0056] Optionally, the ground device includes a turntable device, and the turntable device is used to adjust the driving direction of the transport vehicle 1.

[0057] In this embodiment, the turntable device can load the transport vehicle 1 and drive the transport vehicle 1 to rotate, so that the transport vehicle 1 can leave the current driving road and realize the change of driving direction; the turntable device can be controlled by a pre-built rotation control system and connected to the communication network through wired or wireless communication methods, thereby realizing information interaction between the turntable device and the host computer server.

[0058] Optionally, the ground device includes a lifting device, and the lifting device is used to adjust the height of the running track of the transport vehicle 1.

[0059] In this embodiment, the lifting device can load the transport vehicle 1 and drive the transport vehicle 1 to lift and lower, so that the transport vehicle 1 can leave the current driving road and realize the height conversion of the running track; the lifting device can be controlled by a pre-built lifting control system and connected to the communication network through wired or wireless communication methods, thereby realizing information interaction between the lifting device and the host computer server.

[0060] Optionally, the ground device includes a transverse movement device, which is used to adjust the travel route or travel direction of the transport vehicle 1.

[0061] In this embodiment, the transverse movement device can load the transport vehicle 1 and drive the transport vehicle 1 to move transversely, so that the transport vehicle 1 can leave the current driving road and realize horizontal conversion; the transverse movement device can be controlled by a pre-built transverse movement control system, and access the communication network through wired or wireless communication, thereby realizing information interaction between the transverse movement device and the upper computer server;

[0062] Optionally, the controller is further configured to:

[0063] If the first control signal is obtained, the power taking device 3 is controlled to obtain electric energy from the power supply device 2 and transmit the obtained electric energy to the transport vehicle 1; if the second control signal is obtained, the power storage device 4 is controlled to provide electric energy for the transport vehicle 1; if the third control signal is obtained, the power taking device is controlled to charge the power storage device.

[0064] In this embodiment, when the transport vehicle 1 is traveling on a road section where the power taking device 3 can be used for power supply, a first control signal will be triggered. At this time, the controller can obtain the first control signal, and the power taking device 3 will be used to power the transport vehicle 1. When the transport vehicle 1 is traveling on a road section where the power taking device 3 cannot be used for power supply, a second control signal will be triggered. At this time, the controller can obtain the second control signal, and the power storage device 4 will be used to power the transport vehicle 1. The transport vehicle 1 can transport goods on any road section, thereby improving the efficiency of transportation. Of course, the power taking device 3 and the power storage device 4 can also be controlled to power the transport vehicle 1 at the same time. When the third control signal is obtained, it means that the power storage device is insufficient and needs to be charged, so the power taking device can be controlled to charge the power storage device so that the power storage device can be charged.

[0065] Optionally, the controller is further configured to:

[0066] The speed and position of the transport vehicle 1 are obtained; if the speed is less than a preset speed threshold and the position is not a preset target position, the transport vehicle 1 is controlled to travel to the target position.

[0067] Figure 2 is a schematic diagram of the structure of another transportation system provided by an embodiment of the present invention, such as Figure 2As shown, the transport system also includes a navigation system 6, and the transport vehicle 1 is provided with a power management system 7, a motion system 8, a sensor system (not shown in the figure), a communication system (not shown in the figure) and a main control system (not shown in the figure). The power management system 7 is used to manage the power supply of the electrical equipment on the transport vehicle 1, the motion system 8 is used to drive the transport vehicle 1 to move, the sensor system is used to collect obstacle information, location information, material information, working status information and speed information of the transport vehicle 1, the communication system is used to realize information interaction between the transport vehicle 1 and the upper computer server by wireless communication, and the main control system is used to manage the motion system, the sensor system and the communication system, and is the control core of the transport vehicle 1.

[0068] The sensor system includes an obstacle detection element, a material detection element and a position detection element arranged on the transport vehicle 1. The obstacle detection element is used to collect obstacle information, the material detection element is used to collect material information, and the position detection unit is used to collect position information of the transport vehicle 1.

[0069] In this embodiment, the transportation system 100 also includes a service layer, a network layer and an execution layer. The host computer server is arranged in the service layer, and the host computer server includes a scheduling server, a client and a PLC system. The scheduling server is used to generate subsequent material transportation scheduling tasks based on the received upstream process material information; the client communicates with the scheduling server to realize human-computer interaction; the PLC system is used to execute the scheduling tasks generated by the scheduling server, and is also used to feed back the operating status of the transport vehicle 1 to the scheduling server in real time.

[0070] Figure 3 is a schematic diagram of a transport vehicle structure provided by an embodiment of the present invention, such as Figure 3 As shown, the transport vehicle 1 comprises rail running wheels 11 , and the rails 5 comprise road running wheels 51 .

[0071] In this embodiment, the controller can also set an IP address number for the transport vehicle 1 through the scheduling server, create a list of transport vehicles 1 in the order of the IP address number, and send the operating status and location information, step sequence and material information on the transport vehicle 1 to the scheduling server in real time, so that the scheduling server can update the information of each transport vehicle 1 in the transport vehicle 1 list.

[0072] In this embodiment, the scheduling server will send the generated scheduling task to the controller. The controller is also used to determine the driving information of the transport vehicle 1 according to the scheduling task, and control the turntable device, the lifting device and the transverse device according to the driving information to adjust the driving direction, the running track height and the driving route of the transport vehicle 1, so that the transport vehicle 1 can transport the material to the corresponding unloading position, and then the unloading device will unload the material from the transport vehicle 1. When the transport vehicle 1 completes the feeding task, the controller will generate a return driving route for the transport vehicle 1, and the transport vehicle 1 will return to the corresponding receiving position according to the return route and start to execute the next feeding task.

[0073] In this embodiment, the position detection element can be a proximity switch, and the stopper and RFID tag (Radio Frequency Identification, electronic tag) of the proximity switch are arranged at the target position. An RFID reader is arranged on the transport vehicle 1. When the transport vehicle 1 travels to the target position, the RFID reader will read the position information in the RFID tag. Therefore, when the speed of the transport vehicle 1 is less than the preset speed threshold, and the RFID reader just reads the position information in the RFID tag, it means that the transport vehicle 1 is accurately stopped at the target position. Among them, the speed threshold is 0.

[0074] If the vehicle speed is 0, the RFID card reader will not read the location information in the RFID tag, indicating that the transport vehicle 1 has not reached the target location. At this time, the controller will calculate the distance L1 between the current position and the target position, and control the transport vehicle 1 to continue to drive forward for a distance of L1, so that the transport vehicle 1 reaches the target location. If the vehicle speed is before 0, the RFID card reader will read the location information in the RFID tag, indicating that the transport vehicle 1 has exceeded the target location. At this time, the controller will calculate the distance L2 between the current position and the target position, and control the transport vehicle 1 to drive backward for a distance of L2, so that the transport vehicle 1 reaches the target location.

[0075] Optionally, the controller is further configured to:

[0076] The position of the transport vehicle 1 is obtained; if the position is a preset deceleration position, the transport vehicle 1 is controlled to decelerate.

[0077] In this embodiment, a deceleration position may be set, and the identification method of the deceleration position is the same as the identification method of the target position. When the transport vehicle 1 reaches the deceleration position, the transport vehicle 1 is controlled to decelerate so that the vehicle speed of the transport vehicle 1 can be 0 when it reaches the target position.

[0078] If the vehicle speed is 0 and the transport vehicle 1 has not reached the target position, the distance between the current position of the transport vehicle 1 and the target position is L3, L3=L0 (the distance between the deceleration position and the target position)-L4 (the distance between the deceleration position and the current position), and then the transport vehicle 1 is controlled to continue to move forward at a low speed for a distance of L1 and then stop; if the transport vehicle 1 has passed the target position before the vehicle speed is 0, the controller calculates the distance L5 between the current position and the target position, L3=L4 (the distance between the deceleration position and the current position)-L0 (the distance between the deceleration position and the target positioning position), and then controls the transport vehicle 1 to move backward at a low speed for a distance of L4 and then stop.

[0079] Optionally, the controller is further configured to:

[0080] Obtain the number of transport vehicles 1 whose distance from the turntable device is less than a preset distance threshold; if the number is greater than the preset number threshold, obtain the vehicle density and vehicle priority on each track 5; determine the passage order of the transport vehicles 1 through the turntable device based on the vehicle density and vehicle priority.

[0081] In this embodiment, when multiple transport vehicles 1 pass through a turntable device at the same time, the controller controls the dispatch server to determine the passing order of the transport vehicles 1 according to the priority of the transport vehicles 1 and the vehicle density on each track 5 at this time. The transport vehicle 1 with a higher priority or the transport vehicle 1 on the track 5 with a greater vehicle density will pass first.

[0082] Among them, the priority can be determined according to the urgency of the transportation task.

[0083] In this embodiment, the controller will also adjust the maximum vehicle density of the transport vehicles 1 on each track 5 according to the vehicle density on each track 5 and the operation status of the transport vehicles 1.

[0084] In addition, the execution layer of the transport system 100 also includes execution equipment such as a slapping machine, a weighing device, a baler, a number spraying machine, and an overhead crane. These execution equipment are connected to the communication network to exchange information with the host computer server. The controller controls the dispatch server to comprehensively arrange the work of each execution equipment according to the dispatch task to achieve process docking with the transport vehicle 1. The controller also controls the dispatch server to send the material information and the target storage location number to the PLC system, and the PLC system sends the material information and the target storage location number to the corresponding transport vehicle 1. The transport vehicle 1 will complete the tasks of baling, checking, slapping, number spraying, weighing, etc. of the material under the coordination of the PLC system, and transport the material to the corresponding storage location according to the storage location number, and then the unloading device will put the material into storage.
