Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described here.

[0040] like Figure 1 As shown, the embodiment of the present invention relates to a method for weighing and calculating trucks in an open-pit coal mine, and the method includes the following steps S101 to S103:

[0041] Step S101: receiving a weighing request of an open-pit coal mine truck.

[0042] Specifically, in this step, the open-pit coal mine truck weighing request input by the user can be obtained through the keyboard, mouse and other input devices of the mobile terminal set on the open-pit coal mine truck. Alternatively, the keyboard, mouse and other input devices of the mobile terminal set at the place where weighing is required can be used to obtain the open-pit coal mine truck weighing request input by the user.

[0043] Step S102: Based on the weighing request, a weighing signal of the open-pit coal mine truck is obtained through a weighing sensor installed on the open-pit coal mine truck.

[0044] Specifically, in this embodiment, the weighing sensor can be installed on the rear axle of the vehicle under the truck bed. By stretching the pull rope after loading the cargo, the weight of the loaded cargo can be calculated, and the weight of the vehicle during transportation can be monitored in real time, which helps prevent vehicle overloading and unbalanced loads, and improves transportation safety and the service life of the vehicle.

[0045] Step S103: Calculate the weight of the coal loaded on the open-pit coal mine truck based on the weighing signal.

[0046] The weighing and calculating method for open-pit coal mine trucks of the embodiment of the present invention can accurately measure and calculate the weight of the coal transport truck by using a weighing sensor to measure the weight of the coal loaded on the open-pit coal mine truck, thereby improving work efficiency, ensuring safety, and optimizing resource utilization. In addition, even in a harsh working environment, the weighing and calculating method of the embodiment of the present invention can accurately and stably measure the weight of the coal loaded on the open-pit coal mine truck, thereby enhancing reliability.

[0047] In some possible embodiments, the weighing request carries the open-pit coal mine truck ID, the measurement timestamp and the location information of the open-pit coal mine truck. After obtaining the weight of the coal loaded by the open-pit coal mine truck, the method further includes:

[0048] The coal mine weight is associated with the open pit coal mine truck ID, a measurement timestamp, and location information of the open pit coal mine truck.

[0049] The open-pit coal mine truck weighing and calculation method of the embodiment of the present invention can accurately record the specific circumstances of each weighing, including which vehicle, when, and where the weighing was performed, by associating the truck ID, timestamp, and location information. Historical data can be easily queried and analyzed to help managers understand the transportation situation within a certain period of time and discover potential problems and trends. Combining data of multiple dimensions (such as truck ID, timestamp, and location information) can cross-verify the accuracy of the weighing results and reduce the errors caused by a single data source. Through location information and timestamps, real-time corrections can be made during the data processing stage, such as considering the impact of ground conditions at different locations on the weighing results. In addition, the specific location and load conditions of each vehicle can be known, so that transportation tasks can be arranged more reasonably, empty trips and repeated transportation can be avoided, and overall logistics efficiency can be improved. Combined with location information, the transportation route can be optimized, the best route can be selected, and transportation time and cost can be reduced.

[0050] In some possible embodiments, based on the weighing request, obtaining a weighing signal of the open-pit coal mine truck through a weighing sensor installed on the open-pit coal mine truck includes:

[0051] Based on the weighing request, an initial weighing signal and an ambient temperature signal of the open-pit coal mine truck are respectively obtained through a weighing sensor and a temperature sensor installed on the open-pit coal mine truck;

[0052] The initial weighing signal is temperature compensated based on the ambient temperature signal to obtain the final weighing signal.

[0053] It should be noted that there is no description on how to implement temperature compensation, for example, designing a temperature compensation algorithm based on the temperature characteristics of the sensor. Common methods include linear compensation, polynomial compensation, and table lookup. The collected temperature signal is input into the temperature compensation algorithm, the initial weighing signal is corrected, and the final weighing result is obtained.

[0054] The open-pit coal mine truck weighing and calculation method of the embodiment of the present invention can improve the weighing accuracy. Temperature changes will have a significant impact on the output signal of the sensor, especially the pressure sensor. Through temperature compensation, this impact can be eliminated or reduced, making the weighing result more accurate. Under different temperature conditions, the characteristics of the sensor may change. Temperature compensation can ensure that the weighing results remain consistent at different temperatures and avoid measurement errors caused by temperature fluctuations. In addition, the ambient temperature of the open-pit coal mine varies greatly, from the cold winter to the hot summer. Temperature compensation can enable the system to work normally under extreme temperature conditions. Through temperature compensation, the frequency of regular calibration can be reduced, and the maintenance cost and workload can be reduced. Temperature compensation can reduce the wear and aging of the sensor due to temperature changes and extend the service life of the sensor.

[0055] In some possible embodiments, after obtaining the weight of the coal loaded on the open-pit coal mine truck, the method further includes:

[0056] The coal mine weight is compared with the coal mine weight threshold level, the coal mine weight threshold level of the coal mine weight is determined according to the comparison result, and a corresponding alarm prompt signal is generated.

[0057] Specifically, in this embodiment, different coal mine weight threshold levels can be set according to the specific conditions and safety standards of the mine, such as light load, normal load, heavy load, overload, etc. The alarm logic is designed to generate a corresponding alarm prompt signal when the coal mine weight exceeds a certain threshold. For example, the alarm prompt signal is output through visual (such as indicator light, display screen) and auditory (such as buzzer) methods.

[0058] In the open-pit coal mine truck weighing and calculating method of the embodiment of the present invention, when the weight of the coal mine exceeds the set threshold, the system can immediately generate an alarm prompt signal to remind the operator to pay attention to the risk of overloading and take timely measures to avoid safety accidents caused by overloading. Through real-time monitoring and alarm, potential safety hazards, such as damage to the vehicle structure and tire wear, can be discovered in time, so as to take preventive measures to reduce the probability of accidents. In addition, according to the coal mine weight threshold level, transportation tasks can be more reasonably scheduled to avoid empty or overloaded, and transportation efficiency can be improved. By real-time monitoring of the load of each vehicle, resource allocation can be optimized, unnecessary transportation times can be reduced, and operating costs can be reduced.

[0059] In some possible embodiments, after obtaining the weight of the coal loaded on the open-pit coal mine truck, the method further includes: pushing the weight of the coal loaded on the open-pit coal mine truck to a mobile terminal.

[0060] In some possible embodiments, the weighing sensor is a plurality of pressure sensors distributed on the tires of the open pit coal mine truck;

[0061] The weighing signal of the open-pit coal mine truck is obtained by a weighing sensor installed on the open-pit coal mine truck, and the weight of the coal loaded on the open-pit coal mine truck is calculated based on the weighing signal, including: respectively obtaining the pressure signals detected by each of the pressure sensors; performing weighted averaging on the pressure signals detected by each of the pressure sensors to calculate an average pressure signal; and calculating the weight of the coal loaded on the open-pit coal mine truck based on the average pressure signal.
