[0032] Embodiment 1

[0033] Figure 1 A structural schematic diagram of a weighing system for a mining dump truck is provided for the first embodiment of the present invention. The system comprises: a main controller 110 and an engine controller 120 connected to the main controller 110 .

[0034] Optionally, the main controller 110 is used to obtain the driving information of the mining dump truck and the pressure data of the cargo box. When the driving information meets the preset conditions, the pressure data is converted into weight information, and the overload condition of the weight information is determined. When the overload condition is overload, the weight information is subdivided to generate a torque limit control message, and the torque limit control message is sent to the engine controller 120. When the overload condition is not overloaded, a torque limit cancellation message is generated, and the torque limit cancellation message is sent to the engine controller 120; the engine controller 120 is used to receive the torque limit control message and the torque limit cancellation message, and perform torque limitation according to the torque limit control message, and cancel the torque limitation according to the torque limit cancellation message.

[0035] Among them, the weighing system for a mining dump truck refers to a combination of equipment specifically used for mining dump trucks. Its main function is to measure the weight of the vehicle's cargo and take control measures when it is overloaded to ensure the safe operation of the vehicle and comply with transportation regulations. The main controller 110 is the core control unit of the entire system and can receive and process a variety of data. The driving information includes the gear position and speed of the vehicle, which is used to determine whether the vehicle is in a suitable state for weighing operations. The cargo box pressure data is obtained by a pressure sensor 130 installed at the bottom of the cargo box or on the supporting structure. The pressure sensor 130 can sense the pressure generated by the weight of the cargo in the cargo box on the cargo box. The weight information refers to the data representing the weight of the cargo in the cargo box obtained by converting the pressure data. The overload condition is the result obtained by comparing the calculated weight information with the maximum safe cargo weight designed for the vehicle. If the weight information exceeds the maximum safe cargo weight, it is determined to be overloaded. The torque limit control message refers to the information containing the engine torque limit instruction generated according to the weight information when the main controller 110 determines that the vehicle is overloaded. The torque limit control message will be sent to the engine controller 120 to control the power output of the engine. The engine controller 120 is a device that controls the working state of the engine. It can receive the torque limit control message sent by the main controller 110. According to the instructions in the message, it limits the torque output of the engine by changing the fuel injection amount, intake amount and other parameters of the engine, thereby controlling the power of the vehicle and avoiding safety hazards caused by overloading. When the overload condition is not overloaded, the main controller will also generate a torque limit cancellation message to cancel the torque limit of the engine controller, realize closed-loop control, and avoid engine errors.

[0036] Specifically, the main controller 110 can obtain the driving information of the mining dump truck, such as the vehicle speed, gear position, etc., and the pressure data of the cargo box through sensors and other equipment. When the driving information meets the preset conditions, it means that the vehicle is in a state suitable for weighing, such as the gear position is 0 and the vehicle speed is ≤2km / h. The main controller 110 can determine whether the vehicle is overloaded by comparing the calculated weight with the preset maximum safe load. When it is judged to be overloaded, the main controller 110 can generate a torque limit control message, which contains instruction information about limiting the engine torque.

[0037] Specifically, the engine controller 120 is connected to the main controller 110 and is responsible for receiving the torque limiting control message from the main controller 110. The engine controller 120 can limit the torque according to the torque limiting control message, thereby effectively ensuring the safe operation of the vehicle and the service life of the road.

[0038] Figure 2 A structural schematic diagram of a weighing system for a mining dump truck is provided for the first embodiment of the present invention. Figure 2The system further includes a pressure sensor 130 connected to the main controller 110. The main controller 110 specifically includes a signal conversion unit 111, a data processing unit 112 and a display unit 113.

[0039] Optionally, the system further includes: a pressure sensor 130 connected to the main controller 110 ; the pressure sensor 130 is used to detect pressure data of the cargo box of the mining dump truck and send the pressure data to the main controller 110 .

[0040] The pressure sensor 130 is used to detect the pressure data of the cargo box of the mining dump truck. When the cargo box is loaded with cargo, the weight of the cargo will act on the bottom of the cargo box and the supporting structure, thereby causing pressure on the pressure sensor 130. The pressure sensor 130 can continuously detect the pressure of the cargo box and send real-time pressure data to the main controller 110. The pressure sensor 130 provides the system with accurate pressure data, so that the main controller 110 can effectively calculate the weight and judge overload, thereby ensuring the safe operation of the mining dump truck.

[0041] Optionally, the pressure sensor 130 is also used to perform a self-test when the power is turned on. When the self-test result is normal, it starts to detect the pressure data of the cargo box of the mining dump truck. When the self-test result is abnormal, it generates a prompt message and sends the prompt message to the main controller 110.

[0042] Among them, through self-checking, the pressure sensor 130 can promptly discover possible faults or problems in itself, avoid erroneous pressure data measurement due to sensor failure, and thus ensure the accuracy of the weighing results and the safety of the system.

[0043] Specifically, the self-test includes hardware testing and software testing. When performing hardware testing, the pressure sensor 130 can check whether its own circuit connection is normal. For example, check whether the power supply line is stably powered and whether the signal transmission line is unobstructed. If the power supply line has problems such as open circuit, short circuit or unstable voltage, or there is interference or disconnection in the signal transmission line, it will affect the normal operation of the sensor. When performing software testing, the pressure sensor 130 can check whether the software function is normal through the built-in self-test program. For example, check whether the calibration data of the sensor is correct, whether the algorithm of the sensor is running normally, etc. At the same time, the communication protocol of the sensor can also be checked to ensure that the sensor can communicate normally with the main controller 110. If there is an error in the communication protocol, the sensor will not be able to accurately send the pressure data to the main controller 110.

[0044] Further, when the self-test result is normal, the pressure sensor 130 can start to detect the pressure data of the cargo box of the mining dump truck. At this time, the sensor will continuously send the detected pressure data to the main controller 110 according to the preset sampling frequency and accuracy. After receiving the pressure data, the main controller 110 will further process and analyze it to determine the weight information of the goods in the cargo box. When the self-test result is abnormal, the pressure sensor 130 will generate a prompt message. The prompt message can be a specific error code or alarm signal, which is used to inform the main controller 110 that there is a problem with the pressure sensor 130. The pressure sensor 130 will send the generated prompt message to the main controller 110. After receiving the prompt message, the main controller 110 can take corresponding measures, such as issuing an alarm, notifying the operator to check and repair, etc. At the same time, the main controller 110 can also make corresponding adjustments to the system as needed, such as suspending the weighing function, to avoid wrong judgments and decisions due to wrong pressure data.

[0045] Optionally, the main controller 110 specifically includes: a signal conversion unit 111 and a data processing unit 112; the signal conversion unit 111 is used to convert pressure data into an electrical signal, and amplify and filter the electrical signal to generate a processed electrical signal, and send the processed electrical signal to the data processing unit 112; the data processing unit 112 is used to calculate the processed electrical signal to generate weight information, and determine the overload condition of the weight information. When the overload condition is overload, determine the target weight interval corresponding to the weight information, and generate a torque limit control message according to the target weight interval.

[0046] Among them, the main controller 110 is composed of a signal conversion unit 111 and a data processing unit 112. The cargo box pressure data detected by the pressure sensor 130 is usually a physical quantity, such as a pressure value. The signal conversion unit 111 can convert the pressure data into an electrical signal. The converted electrical signal is often relatively weak and needs to be amplified. The amplifier circuit can use devices such as operational amplifiers to enhance the electrical signal according to the size and characteristics of the input electrical signal according to a preset amplification factor. In addition, in actual environments, electrical signals may be subject to various interferences, such as electromagnetic interference, noise, etc. The purpose of filtering is to remove these interference signals and retain useful signal components. The processed electrical signal will be sent to the data processing unit 112.

[0047] Specifically, after receiving the processed electrical signal, the data processing unit 112 converts the electrical signal into weight information according to the preset algorithm and calibration parameters. For example, if it is known that there is a linear relationship between pressure and weight, the corresponding weight value can be calculated by measuring the electrical signal strength and the known proportionality coefficient. The data processing unit 112 can compare the calculated weight information with the preset safe load to determine whether the vehicle is overloaded. If the weight information exceeds the safe load, it is determined to be an overload situation; otherwise, it is not an overload situation. When the overload situation is determined to be an overload, the data processing unit 112 further determines the target weight interval corresponding to the weight information. This can be achieved by dividing different weight ranges into multiple intervals. Each interval can correspond to different degrees of overload and corresponding torque limiting control strategies. For example, when G≥Gmax*125%, the main controller sends a torque limit request to the engine controller 120 to limit the torque by 25%; when G≥Gmax*150%, the torque limit is 50%; when G≥Gmax*175%, the torque limit is 75%; wherein G is the real-time monitoring weight information uploaded by the weighing system, and Gmax is the safe load. Finally, according to the target weight range, the data processing unit 112 can generate a torque limit control message to instruct the engine controller 120 to limit the torque to a corresponding degree. For example, for a lighter degree of overload, only a smaller torque limit may be required; while for a severe overload, a larger torque limit is required.

[0048] Optionally, the main controller 110 also includes: a display unit 113; the main controller 110 is also used to unlock the display unit 113 when the driving information meets the preset conditions, and lock the display unit 113 when the driving information does not meet the preset conditions, wherein the driving information includes the gear position and the vehicle speed.

[0049] The display unit 113 can provide key information to the driver or operator, such as the load condition of the vehicle, whether it is overloaded, and the weight information after the cargo box pressure data is converted. The preset condition is set according to the normal working state and safety requirements of the vehicle. For example, the preset condition may be that the vehicle is in a certain gear range (such as 0 gear) and the vehicle speed is less than a certain value (such as less than 2km / h). When the vehicle is in a suitable gear and at a lower speed, the system can more stably acquire and process data.

[0050] Specifically, when the driving information meets the preset conditions, the main controller 110 will release the lock state of the display unit 113 through the internal control circuit and software logic. For example, the power control circuit of the display unit 113 can be controlled so that the display unit 113 can be powered normally, or the display function of the display unit 113 can be activated through software instructions. When the driving information of the vehicle does not meet the preset conditions, for example, when the vehicle is in a driving state, the information displayed by the display unit 113 may change frequently due to the unstable state of the vehicle, resulting in distraction of the driver's attention. Therefore, the main controller 110 will lock the display unit 113. Specifically, the display unit 113 can be put into a dormant or standby state by cutting off the power supply of the display unit 113 or sending a lock signal to the display unit 113 to prevent it from displaying information in an inappropriate vehicle state.

[0051] The technical solution of the embodiment of the present invention obtains driving information and cargo box pressure data through the main controller, and performs precise conversion and calculation to obtain more accurate weight information, and limits the engine torque through the torque limit control message when overloaded, thereby reducing the risk of vehicle operation and ensuring safety during mine transportation. When the driving information meets the conditions, weight conversion and overload judgment are immediately performed, and real-time monitoring is realized. Overload conditions can be discovered in time and measures can be taken quickly, effectively avoiding errors in traditional weighing methods. Vehicle damage and increased maintenance costs caused by overloading are avoided, while the service life of the vehicle is increased and the overall operating cost of the mine is reduced.

[0052] Embodiment 2

[0053] Figure 3 A structural schematic diagram of a weighing system for a mining dump truck is provided for the first embodiment of the present invention. Figure 3 On the basis of the first embodiment, a cargo box tilt sensor 140 is added.

[0054] Optionally, the system further includes: a cargo box inclination sensor 140 connected to the main controller 110 ; the cargo box inclination sensor 140 is used to detect the inclination angle of the cargo box of the mining dump truck and send the inclination angle to the main controller 110 .

[0055] The cargo box tilt sensor 140 can detect the tilt angle of the cargo box in real time, providing key data for accurately calculating the cargo weight and ensuring the safe operation of the vehicle. When the cargo box tilts, the sensitive elements inside the cargo box tilt sensor 140 will sense the change in the direction of gravity, thereby generating a corresponding electrical signal or digital signal output.

[0056] Specifically, the cargo box tilt sensor 140 can continuously detect the tilt angle of the cargo box and send the real-time tilt angle to the main controller 110 .

[0057] Optionally, the main controller 110 is also used to determine whether the tilt angle is 0 when the overload condition is not overloaded, and if so, generate a loading operation instruction, otherwise, generate an unloading operation instruction.

[0058] After the controller determines that the overload situation is not overloaded, it will further determine the tilt angle of the cargo box. By determining the tilt angle of the cargo box, the vehicle can be guided to perform correct loading or unloading operations, ensuring that the vehicle operates in a reasonable state, improving work efficiency while ensuring safety.

[0059] Specifically, when the main controller 110 determines that the vehicle is not overloaded, it starts to pay attention to the tilt angle of the cargo box. If the tilt angle is 0, it indicates that the cargo box is in a horizontal state. At this time, the main controller 110 will think that the vehicle is in a state suitable for loading operations. The main controller 110 can make a judgment by receiving real-time data from the cargo box tilt sensor 140. If the angle value fed back by the tilt sensor is within a very small range (close to 0), it can be considered that the cargo box is basically horizontal. For example, if an allowable error range is set, such as ±0.5 degrees, when the tilt angle is within this range, the main controller 110 determines that the tilt angle is 0. When the tilt angle is 0, it means that the vehicle cargo box is in a stable horizontal state. At this time, loading operations can ensure that the goods are evenly distributed in the cargo box, avoiding uneven stacking of goods or shifting of the center of gravity of the vehicle due to the tilt of the cargo box.

[0060] Specifically, when the main controller 110 determines that the tilt angle is not 0, it means that the cargo box is in a tilted state. At this time, loading operations may cause uneven distribution of cargo, increasing the safety risk during vehicle driving. At this time, the main controller 110 generates an unloading operation instruction. The main controller 110 generates corresponding loading operation instructions or unloading operation instructions through comprehensive judgment of the overload situation and the tilt angle of the cargo box, which can effectively guide the operation process of the mining dump truck and improve operation efficiency and safety.

[0061] The technical solution of the embodiment of the present invention can accurately determine the loading or unloading status of the vehicle by detecting the tilt angle of the cargo box, and generate corresponding instructions to make the operation process more standardized and efficient. It can timely determine the status of the cargo box and give correct instructions to avoid safety hazards such as material spillage or vehicle imbalance caused by abnormal tilt of the cargo box. By accurately judging the loading and unloading conditions, it is helpful to reasonably control the loading and unloading of materials and reduce unnecessary loss and waste of materials. The operation can be adjusted in time according to the tilt angle of the cargo box, the waiting and invalid operation time can be reduced, and the efficiency of the entire mine transportation operation can be improved.

[0064] S310. Acquire the driving information of the mining dump truck and the pressure data of the cargo box through the main controller. When the driving information meets the preset conditions, convert the pressure data into weight information, and determine the overload condition of the weight information. When the overload condition is overload, subdivide the weight information to generate a torque limit control message, and send the torque limit control message to the engine controller. When the overload condition is not overloaded, generate a torque limit cancellation message, and send the torque limit cancellation message to the engine controller.

[0065] Specifically, the main controller can obtain the driving information of the mining dump truck, such as vehicle speed, gear position, etc., as well as the pressure data of the cargo box through sensors and other equipment. When the driving information meets the preset conditions, it means that the vehicle is in a state suitable for weighing, such as the gear position is 0 and the speed is ≤2km / h. The main controller can determine whether the vehicle is overloaded by comparing the calculated weight with the preset maximum safe load. When it is judged to be overloaded, the main controller can generate a torque limit control message, which contains instruction information about limiting the engine torque.

The engine controller can limit the torque according to the torque limit control message, thereby effectively ensuring the safe operation of the vehicle and the service life of the road.

[0068] The technical solution of the embodiment of the present invention obtains driving information and cargo box pressure data through the main controller, and performs precise conversion and calculation to obtain more accurate weight information, and limits the engine torque through the torque limit control message when overloaded, thereby reducing the risk of vehicle operation and ensuring safety during mine transportation. When the driving information meets the conditions, weight conversion and overload judgment are immediately performed, and real-time monitoring is realized. Overload conditions can be discovered in time and measures can be taken quickly, effectively avoiding errors in traditional weighing methods. Vehicle damage and increased maintenance costs caused by overloading are avoided, while the service life of the vehicle is increased and the overall operating cost of the mine is reduced.
