Description

Technical Field

[0001] This invention relates to the field of unmanned mining truck technology, and in particular to an unmanned electric mining truck and its control system. Background Technology

[0002] Current mining truck control systems are all centered around a vehicle control unit (VCU). The VCU connects to the vehicle's power system, steering system, braking system, status information, and other devices via several CAN buses. The VCU typically uses a microcontroller, which has limited computing power and can only perform simple data processing and control. To achieve autonomous driving, a high-performance autonomous driving system controller is required. This controller then communicates with the VCU via the CAN bus to obtain vehicle information or control the vehicle through the VCU.

[0003] In the current system, the autonomous driving system needs to control the vehicle or obtain vehicle information through the VCU, which has problems such as large communication latency, large communication data volume, the autonomous driving system not being able to obtain all vehicle information, information redundancy between the VCU and the autonomous driving system, and duplicate and inconsistent control strategies. This results in long vehicle debugging time and poor operational stability. The cargo box of the current autonomous electric mining truck is shaped like a "√", which reduces the cargo capacity. If a traditional cargo box is used, the baffle on the cargo box needs to be fixed when transporting minerals, and when the autonomous electric mining truck moves to the destination, the baffle needs to be opened manually by the staff, which is very troublesome.

[0036] Example 1

[0037] Reference Figure 1-11 An unmanned electric mining truck and its control system are provided, including a loading mechanism 100, which includes a cargo box 101, a control device 102 disposed at the front of the cargo box 101, and a drive unit 103 disposed on the cargo box 101.

[0038] Furthermore, the drive unit 103 includes a slot 103a and a wire groove 103b disposed on the cargo box 101, a fixing box 103c disposed on the cargo box 101, a drive member 103d disposed inside the fixing box 103c, and a flipping member 103e disposed on the cargo box 101.

[0039] The slot 103a and the wire trough 103b are interconnected, the wire 103b and the fixing box 103c are interconnected, the fixing box 103c is installed on both sides of the cargo box 101, and the fixing box 103c is close to the rear of the cargo box 101.

[0040] Furthermore, the driving component 103d includes a motor 103d-1 disposed on the fixed box 103c, a power cord 103d-2 disposed on the motor 103d-1, and a winding reel 103d-3 disposed on the motor 103d-1.

[0041] The motor 103d-1 is located inside the fixed box 103c. The other end of the power cord 103d-2, away from the motor 103d-1, extends to the outside of the fixed box 103c and connects to the control device 102. The winding reel 103d-3 is connected to the output end of the motor 103d-1.

[0042] Furthermore, the flipping component 103e includes a baffle 103e-1 disposed on the cargo box 101, an insert block 103e-2 disposed on the baffle 103e-1, a wire block 103e-3 disposed on the insert block 103e-2, an insertion port 103e-4 disposed on the insert block 103e-2, and a limiting plate 103e-5 disposed on the baffle 103e-1.

[0043] The baffle 103e-1 is connected to the cargo box 101 via a hinge. The baffle 103e-1 is located at the bottom of the cargo box 101. The insert block 103e-2 is located on the side adjacent to the cargo box. The insert block 103e-3 is installed on the side of the insert block 103e-2 away from the baffle 103e-1. The limiting plate 103e-5 is located on the side away from the insert block 103e-2. The setting of the limiting plate 103e-5 ensures that when the baffle 103e-1 is flipped down around the hinge, the baffle 103e-1 can only be flipped to the bottom horizontal position of the cargo box 101.

[0044] Operation process: Connect one end of the rope to the line block 103e-3, and the other end of the rope to the winding reel 103d-3 via the line groove 103b and slot 103a. Control the motor 103d-1 to start via the control device 102. The motor 103d-1 drives the winding reel 103d-3 to rotate, which in turn winds up the rope. During the winding process, the rope pulls the line block 103e-3, which in turn drives the insert block 103e-2. The insert block 103e-2 drives the baffle 103e-1 to rotate around the hinge. The baffle 103e-1 drives the limit plate 103e-5, which finally inserts the insert block 103e-2 into the slot 103a. At this point, stop the motor 103d-1.

[0045] Example 2

[0046] Reference Figure 1-11 The difference between this embodiment and the first embodiment is that the latching mechanism 200 includes a first chamber 201 disposed on the cargo box 101 and a latching part 202 disposed inside the first chamber 201.

[0047] Furthermore, the snap-fit ​​portion 202 includes a first spring 202a disposed inside the first chamber 201, a plug 202b disposed on the first spring 202a, and a fixing rod 202c disposed on the plug 202b.

[0048] The first chamber 201 is located on the side adjacent to the fixed box 103c, and one end of the first spring 202a is connected to the inner wall of the first chamber 201.

[0049] Furthermore, the connector 202b includes a short rod 202b-1 disposed on the first spring 202a, a first inclined cut surface 202b-2 disposed on the short rod 202b-1, a linear groove 202b-3 disposed on the short rod 202b-1, and a second inclined cut surface 202b-4 disposed on the insert block 103e-2.

[0050] The first chamber 201 is connected to the slot 103a. One end of the short rod 202b-1 is connected to the first spring 202a. The first inclined section 202b-2 is located on the side away from the wire groove 103b. The linear groove 202b-3 is located on the side away from the first chamber 201. The first inclined section 202b-2 and the linear groove 202b-3 are connected. The rope is located inside the linear groove 202b-3. When the insert 103e-2 moves into the slot 103a, the second inclined section 202b-4 comes into contact with the first inclined section 202b-2. Under normal circumstances, there is a certain gap between the short rod 202b-1 and the inside of the slot 103a. The distance of the gap is greater than the size of the wire block 103e-3, just enough for the wire block 103e-3 to pass through.

[0051] Operation process: Driven by motor 103d-1, the rope drives line block 103e-3, which in turn drives insertion block 103e-2. Insertion block 103e-2 then drives baffle 103e-1 to rise. When insertion block 103e-2 moves into slot 103a, the second inclined cut surface 202b-4 contacts the first inclined cut surface 202b-2. At this time, line block 103e-3 is located between short rod 202b-1 and the inner wall of slot 103a. The rope continues to pull line block 103e-3, causing the first inclined cut surface 202b-2 and the second inclined cut surface 202b-4 to gradually separate, and the insertion... Block 103e-2 presses against short rod 202b-1, causing short rod 202b-1 to retract the spring. Short rod 202b-1 then moves fixed rod 202c into the fixed box 103c. When the second inclined cut surface 202b-4 separates from the first inclined cut surface 202b-2, the side wall of the insert block 103e-2 contacts the linear groove 202b-3. The insert block 103e-2 continues to move, causing short rod 202b-1 to move to the insertion port 103e-4. At this time, the first spring 202a resumes its function, causing short rod 202b-1 to insert into the insertion port 103e-4 and limit the position of the insert block 103e-2.

[0052] Example 3

[0053] Reference Figure 1-11 The difference between this embodiment and the above embodiments is that the reset mechanism 300 includes an extension rod 301 disposed on the drive part 103, a turntable 302 disposed on the extension rod 301, a reset part 303 disposed on the turntable 302, and an engagement part 304 disposed on the snap-fit ​​part 202.

[0054] Furthermore, the reset part 303 includes an annular groove 303a disposed on the turntable 302, a flipping block 303b disposed inside the annular groove 303a, a spring-loaded member 303c disposed on the flipping block 303b, and a pop-out member 303d disposed on the cargo box 101.

[0055] The annular groove 303a is located in the middle of the turntable 302, and the flipping block 303b is installed inside the annular groove 303a via a rotating shaft.

[0056] Furthermore, the engagement part 304 includes a movable block disposed on the fixed rod 202c, an elongated hole 304b disposed on the movable block, a rack 304c disposed on the movable block, a limiting rod 304d disposed on the fixed box 103c, and an auxiliary block 304e disposed on the fixed rod 202c.

[0057] Among them, the end of the fixed rod 202c away from the short rod 202b-1 is connected to the moving block, the elongated hole 304b is located on the side away from the fixed rod 202c, the end of the limiting rod 304d away from the fixed box 103c is located inside the elongated hole 304b, the auxiliary block 304e is movably sleeved on the side wall of the fixed rod 202c, and the auxiliary block 304e is installed on the top of the fixed box 103c, and the rack 304c is located at the bottom of the moving block.

[0058] Furthermore, the spring-loaded component 303c includes a second spring 303c-1 disposed on the flip block 303b, and a pull rope 303c-2 disposed on the flip block 303b.

[0059] Wherein, one end of the second spring 303c-1 is connected to the bottom surface inside the annular groove 303a, the other end of the second spring 303c-1 is connected to the bottom plate of the flipping block 303b, the second spring 303c-1 is sleeved on the outside of the pull rope 303c-2, one end of the pull rope 303c-2 is connected to the bottom of the flipping block 303b, and the other end of the pull rope 303c-2 is connected to the bottom surface inside the annular groove 303a;

[0060] Under normal circumstances, the flipping block 303b is in an inclined state. When the moving block moves into the fixed box 103c, the moving block drives the rack 304c to squeeze the flipping block 303b. The flipping block 303b drives the second spring 303c-1 to contract, so that the flipping block 303b can slide into the next tooth groove, preventing the turntable 302 from rotating.

[0061] Furthermore, the ejector 303d includes a second chamber 303d-1 disposed on the cargo box 101, a third spring 303d-2 disposed inside the second chamber 303d-1, and an ejector block 303d-3 disposed on the third spring 303d-2.

[0062] There are two second chambers 303d-1, located above and below the wire groove 103b respectively. The second chambers 303d-1 are interconnected with the slot 103a. One end of the third spring 303d-2 is connected to the inner wall of the second chamber 303d-1, and the other end of the third spring 303d-2 is connected to the ejector block 303d-3.

[0063] When the insert block 103e-2 is inside the slot 103a, the insert block 103e-2 presses the ejector block 303d-3, causing the ejector block 303d-3 to drive the third spring 303d-2 to remain in a contracted state.

[0064] Operation process: When the baffle 103e-1 needs to be lowered, the motor 103d-1 is started, causing the motor 103d-1 to rotate in reverse. When the motor 103d-1 rotates in reverse, the rope wound on the take-up reel 103d-3 will be lowered first. At the same time, the top of the flipping block 303b contacts the rack 304c, and the motor 103d-1 drives the extension rod 301 to rotate. The extension rod 301 drives the turntable 302 to rotate. At this time, the flipping block 303b pulls the pull rope 303c-2, making the pull rope 303c-2 taut. The flipping block 303b drives the moving block to move away from the fixed rod 202c, so that the moving block... The block slides on the limiting rod 304d, the moving plate 304a drives the fixed rod 202c to move, the fixed rod 202c moves on the auxiliary block 304e, the fixed rod 202c drives the short rod 202b-1 to move into the first chamber 201, the short rod 202b-1 drives the first spring 202a to contract, so that the short rod 202b-1 disengages from the inside of the insertion port 103e-4. At this time, the third spring 303d-2 recovers and drives the ejector block 303d-3 to push the insertion block 103e-2 out of the inside of the slot 103a, so that the baffle 103e-1 gradually falls down to be horizontal with the bottom of the cargo box 101, which facilitates the unloading of the mining truck.

[0065] Example 4

[0066] Reference Figure 12 This embodiment differs from the previous embodiments in that it is a control system comprising: an information processing module for collecting operating data of various devices; a control module for controlling the normal operation of various devices; and an output module for outputting according to the operation instructions transmitted by the control module.

[0067] Furthermore, the information processing module includes an information network, an indicator light electrically connected to the information network, an air conditioner electrically connected to the information network, and a wheel status information database electrically connected to the information network.

[0068] The indicator lights, air conditioning, and vehicle status information modules are connected to an information network and then to the central controller. The information network uses the CAN bus protocol. There is bidirectional data exchange between the central controller and the indicator lights, air conditioning, and vehicle status information modules; that is, the central controller sends control commands, and the indicator lights, air conditioning, and vehicle status information modules upload execution status and information.

[0069] Furthermore, the control module includes a main controller electrically connected to an information network, an autonomous driving controller electrically connected to the main controller, a battery system electrically connected to the main controller, and a protection controller electrically connected to the main controller.

[0070] The battery system involves a large amount of communication data. It connects to the main controller via a dedicated battery system network using the CAN bus protocol, with the communication rate adjustable to high-speed mode. Data exchange between the battery system and the main controller is bidirectional.

[0071] The main controller employs a high-performance processor to meet the needs of vehicle control and autonomous driving system operation. Generally, a multi-core processor or a heterogeneous processor can be used.

[0072] The main controller and the protection controller are connected via a serial interface, and the protection controller is connected to the critical control network. The main controller sends heartbeat detection data packets to the protection controller at regular intervals, and the protection controller sends a data packet back to the main controller upon receiving the heartbeat detection data packet. When the protection controller normally receives the heartbeat detection data packet from the main controller, the communication interface between the protection controller and the critical control network is closed.

[0073] Furthermore, the output module includes a key control network electrically connected to the main controller, a main power supply electrically connected to the main controller, a power system electrically connected to the main controller, a steering system electrically connected to the main controller, and a braking system electrically connected to the main controller.

[0074] The main power supply, power system, braking system, and steering system are connected to the key control network and then to the main controller. The key control network uses the CAN bus protocol. There is bidirectional data exchange between the main controller and the main power supply, power system, braking system, and steering system; that is, the main controller issues control commands, and the main power supply, power system, braking system, and steering system upload execution status and position information.

[0075] If the protection controller does not receive a heartbeat detection data packet from the main controller within the set time interval, it will open the communication interface between the protection controller and the critical control network and send a series of emergency stop commands to the critical control network to shut down the vehicle's power system, activate the braking system, and shut down the main power supply to achieve a safe stop of the vehicle. At the same time, it will receive corresponding feedback data. If it does not receive the correct feedback data, the protection controller will continue to send a series of emergency stop commands.

[0076] If the main controller sends a heartbeat detection data packet to the protection controller and does not receive feedback data from the protection controller within the set time interval, the main controller sends a series of emergency stop instructions to the critical control network to shut down the vehicle's power system, activate the braking system, and shut down the main power supply to achieve a safe stop of the vehicle. At the same time, it receives corresponding feedback data. If it does not receive the correct feedback data, the main controller continues to send a series of emergency stop instructions.

[0077] Working principle;

[0078] It integrates the autonomous driving controller and VCU, and realizes vehicle control and autonomous driving functions through a high-performance master controller;

[0079] The control network is divided into three networks: a key control network, a battery system network, and an information network.

[0080] It is configured with a protection controller that, when the main controller malfunctions, shuts down the vehicle's power system, engages the braking system, and shuts down the main power supply through the critical control network, thereby ensuring the vehicle stops safely.
