Description

Technical Field

[0001] The present invention relates to the field of computer technology, and particularly to a vehicle weighing method, device, mining truck and storage medium. Background Art

[0002] At present, transporting ore and rock by large-tonnage heavy trucks is one of the main forms of transportation in large open-pit mining areas. In order to improve transportation efficiency, it is particularly important to deploy an automatic weighing system on mining trucks.

[0003] When the existing mining trucks are weighed, the load weight is usually obtained by subtracting the empty vehicle weight of the actual vehicle from the full load weight. However, when determining the empty vehicle weight, the goods not completely emptied in the cargo box are not considered. Different degrees of sticking of the cargo box will cause great changes in the weighing error. Moreover, the weighing error of the same weighing system is different for different mining areas and different sources of goods. Secondly, after calibrating the empty vehicle weight, the corresponding weighing data of the existing weighing system will no longer be changed, resulting in a low accuracy of the weighing result.

[0043] In order to enable those skilled in the art to better understand the solutions of the present invention, the following clearly and completely describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above accompanying drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0045] Figure 1a The flowchart of a vehicle weighing method provided by an embodiment of the present invention. This embodiment is applicable to the situation where a mining truck calibrates its empty weight. This method can be executed by a vehicle weighing device, which can be implemented in the form of hardware and / or software, and can be configured in a mining truck. As Figure 1a shown, this method includes:

[0046] Step 110: After detecting that the vehicle triggers a lifting action, determine whether the vehicle is in an empty load state according to the currently reduced load weight of the vehicle.

[0047] In this embodiment, Figure 1b it can be a schematic structural diagram of a vehicle weighing system in a mining truck. As Figure 1b shown, it can be detected whether the vehicle triggers a lifting action through a lifting sensor 101. After the vehicle triggers a lifting action, a load system controller 102 can transmit a weighing command to a load sensor 103, and the load sensor 103 can weigh the current weight of the vehicle and determine the currently reduced weight of the vehicle according to the current weight and the original weight.

[0048] Specifically, if the currently reduced load weight of the vehicle meets a preset threshold, the load system controller 102 can determine that the vehicle is currently unloaded and in an empty load state, and then execute step 120. On the contrary, if the currently reduced load weight of the vehicle does not meet the preset threshold, the load system controller 102 can determine that the vehicle is not currently in an empty load state, and then continue to return to execute the operation of step 110.

[0049] Step 120: If the vehicle is in an empty load state, determine whether the vehicle meets the empty load calibration condition according to the power-on state, vehicle speed, and vehicle body inclination of the vehicle.

[0050] In this embodiment, if the vehicle is in an empty load state, the power-on state and vehicle speed corresponding to the vehicle can be obtained, and the vehicle body inclination can be determined through a gyroscope 104 of a vehicle control unit (VCU).

[0051] Specifically, when the vehicle electronic system is powered on, the vehicle speed is zero, and the inclination meets the preset threshold, the load system controller 102 can determine that the vehicle meets the empty load calibration condition and execute step 130. On the contrary, if the vehicle electronic system is not powered on, or the vehicle speed is not zero, or the inclination does not meet the preset threshold, it can be determined that the vehicle does not meet the empty load calibration condition, and then continue to return to execute the operation of step 120 until the vehicle meets the empty load calibration condition.

[0052] Step 130: If the vehicle meets the no-load calibration condition, calibrate the current weight of the vehicle as the no-load weight corresponding to the vehicle.

[0053] In this step, if the vehicle meets the no-load calibration condition, the load system controller 102 can send a weighing command to the load sensor 103 to enable the load sensor 103 to determine the current weight of the vehicle and calibrate the current weight of the vehicle as the no-load weight.

[0054] In this embodiment, by combining the power-on state, vehicle speed, and inclination of the vehicle to determine whether the vehicle meets the no-load calibration condition, weighing errors caused by unemptied goods in the vehicle can be avoided; secondly, after each lifting action of the vehicle, calibrating the no-load weight according to the no-load state of the vehicle can correct the inaccurate no-load weight, thereby improving the accuracy of the vehicle weighing result.

[0055] The technical solution provided by the embodiment of the present invention, after detecting that the vehicle triggers a lifting action, determines whether the vehicle is in a no-load state according to the currently reduced load of the vehicle. If so, determines whether the vehicle meets the no-load calibration condition according to the corresponding power-on state, vehicle speed, and overall vehicle inclination of the vehicle. If so, calibrates the current weight of the vehicle as the no-load weight corresponding to the vehicle, which can avoid weighing errors caused by unemptied goods in the vehicle and improve the accuracy of the vehicle weighing result.

[0056] Figure 2 It is a flowchart of another vehicle weighing method provided by the embodiment of the present invention, as Figure 2 shown, this method includes:

[0057] Step 210: After detecting that the vehicle triggers a lifting action, determine the proportion of the corresponding weight change of the vehicle according to the currently reduced load of the vehicle and the original total vehicle load of the vehicle.

[0058] In this step, the currently reduced load of the vehicle can be divided by the original total vehicle load to obtain the proportion of the corresponding weight change of the vehicle.

[0059] Step 220: If the proportion of the weight change is greater than a preset ratio, determine that the vehicle is in a no-load state.

[0060] In a specific embodiment, if the proportion of the weight change is greater than or equal to 70%, it can be determined that the vehicle is in a no-load state. Among them, the preset ratio can be adjusted according to the actual situation, and this embodiment does not limit this.

[0061] The advantage of such a setting is that it can accurately identify the no-load state of the vehicle and improve the effectiveness of the vehicle weighing result.

[0062] Step 230: If the vehicle is in an unloaded state, the ignition switch corresponding to the vehicle is in the on state, the vehicle speed is zero, and the overall vehicle inclination is less than a preset inclination, it is determined that the vehicle meets the unloaded calibration condition.

[0063] In this step, specifically, if the vehicle is in an unloaded state, the ignition switch is on, the vehicle speed is zero, and the overall vehicle inclination is less than 1 degree, it can be determined that the vehicle meets the unloaded calibration condition. Among them, the preset inclination can be adjusted according to the actual situation, and this embodiment does not limit this.

[0064] Step 240: Calibrate the current weight of the vehicle as the unloaded weight corresponding to the vehicle.

[0065] Step 250: Store the mapping relationship between the unloaded weight corresponding to the vehicle and the current time in the database.

[0066] In this embodiment, after calibrating the unloaded weight of the vehicle, the unloaded weight and the current time can be stored in the database for subsequent use.

[0067] The technical solution provided by the embodiment of the present invention, after detecting that the vehicle triggers a lifting action, determines the proportion of weight change according to the current reduced load of the vehicle and the original overall vehicle load. If the proportion of weight change is greater than a preset proportion, it is determined that the vehicle is in an unloaded state. If the vehicle is in an unloaded state, the ignition switch is in the on state, the vehicle speed is zero, and the overall vehicle inclination is less than the preset inclination, it is determined that the vehicle meets the unloaded calibration condition, calibrate the current weight of the vehicle as the unloaded weight, and store the mapping relationship between the unloaded weight and the current time in the database. This technical means can avoid weighing errors caused by unemptied goods in the vehicle and improve the accuracy of the vehicle weighing result.

[0068] Figure 3 It is a flowchart of another vehicle weighing method provided by the embodiment of the present invention. As Figure 3 shown, this method includes:

[0069] Step 310: Determine the reference thresholds corresponding to different mining area types and different source types of goods; the reference thresholds include a threshold for the proportion of weight change and a threshold for inclination.

[0070] In practical applications, the weighing errors of the same weighing system for different mining areas and different sources of goods are different. To solve this problem, this embodiment proposes a method of pre-determining the corresponding reference thresholds according to different mining area types and source types of goods before vehicle weighing.

[0071] Step 320: Establish a mapping relationship between different mining area types and different source types of goods and their corresponding reference thresholds.

[0072] For example, assume that the mining area types include Mining Area A and Mining Area B, and the source types of goods include Source C and Source D. The reference thresholds corresponding to different mining area types and different source types of goods can be seen in Table 1.

[0073] Table 1

[0074] Mine area type Source type Threshold of weight change percentage Gradient threshold A C 70％ 0.5 A D 75％ 1 B C 80％ 1.5 B D 85％ 2

[0075] Step 330: After detecting that the vehicle triggers a lifting action, determine the proportion of weight change corresponding to the vehicle according to the current reduced load weight of the vehicle and the original full vehicle load weight of the vehicle.

[0076] Step 340: Obtain the current mining area type and the current source type of goods corresponding to the vehicle, and determine the target proportion threshold according to the current mining area type, the current source type of goods, and the mapping relationship.

[0077] In this step, specifically, assume that the current mining area type corresponding to the vehicle is B and the current source type of goods is C, then the target proportion threshold can be determined to be 80%.

[0078] Step 350: If the proportion of weight change is greater than the target proportion threshold, determine that the vehicle is in an empty load state.

[0079] Step 360: Obtain the current mining area type and the current source type of goods corresponding to the vehicle, and determine the target inclination threshold according to the current mining area type, the current source type of goods, and the mapping relationship.

[0080] In this step, specifically, assume that the current mining area type corresponding to the vehicle is B and the current source type of goods is C, then the target inclination threshold can be determined to be 1.5 degrees.

[0081] The advantage of such a setting is that by setting the reference thresholds corresponding to different mining area types and different source types of goods respectively, the current empty load state of the vehicle can be accurately judged, avoiding different weighing errors of the same weighing system for different mining areas and different sources of goods, thereby improving the effectiveness of the vehicle weighing result.

[0082] Step 370: If the ignition switch corresponding to the vehicle is in the on state, the vehicle speed is zero, and the overall vehicle inclination is less than the target inclination threshold, determine that the vehicle meets the empty load calibration condition.

[0083] Step 380: Calibrate the current weight of the vehicle as the empty load weight corresponding to the vehicle.

[0084] The technical solution provided by the embodiment of the present invention determines the reference thresholds corresponding to different mining area types and different source types of goods respectively. After detecting that the vehicle triggers a lifting action, it determines the proportion of weight change according to the current reduced load of the vehicle and the original full vehicle load. According to the current mining area type, the current source type of goods and the mapping relationship, it determines the target proportion threshold. If the proportion of weight change is greater than the target proportion threshold, it determines that the vehicle is in an empty load state. According to the current mining area type, the current source type of goods and the mapping relationship, it determines the target inclination threshold. If the ignition switch corresponding to the vehicle is in the on state, the vehicle speed is zero, and the overall vehicle inclination is less than the target inclination threshold, it determines that the vehicle meets the empty load calibration condition, and calibrates the current weight of the vehicle as the empty load weight. This technical means can avoid weighing errors caused by unemptied goods in the vehicle and improve the accuracy of the vehicle weighing result.
