[0047] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described clearly and completely in the following with reference to the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0048] The fuel consumption detection method of the present application will be described below. Figure 1 The fuel consumption detection method of the present application is executed by the hardware and / or software in the host computer of the working machine. As shown in Figure 1 , the fuel consumption detection method of the present application at least includes the following steps:

[0049] S101, obtaining the working time and the current working state of the working machine;

[0050] S102, determine the current oil consumption of the working machine based on one or more of a plurality of types of oil consumption data corresponding to the current working parameter data of the working machine, the working time length and the current working state, wherein the plurality of types of oil consumption data include historical average oil consumption, calibrated average oil consumption, average oil consumption of the last working, average oil consumption of the current working and current instantaneous oil consumption.

[0051] In the embodiment, the working parameter of the working machine can include a working mode and / or a working gear, and the current working parameter data of the working machine is the working mode and / or the working gear of the working machine at the current time. The working time length of the working machine can be the time length from the factory delivery time of the working machine to the current time, or the total time length during which the working machine is in the working state from the factory delivery time to the current time. The working time length of the working machine can effectively represent the equipment state of the working machine. The current working state of the working machine can be a preheating state or a preheating completion state, and the current working state of the working machine can be determined based on the current value of the state parameter of the working machine. The state parameter can include water temperature and / or hydraulic oil temperature. For example, if the water temperature and / or the hydraulic oil temperature is greater than or equal to the corresponding temperature threshold, it is determined that the current working state of the working machine is the preheating completion state, and if the water temperature and / or the hydraulic oil temperature is less than the corresponding temperature threshold, it is determined that the current working state of the working machine is the preheating state. The current value of the state parameter of the working machine can be sent from the lower machine of the working machine to the upper machine.

[0052] The historical average oil consumption corresponding to the current working parameter data can be the average value of the oil consumption corresponding to the current working parameter data of the working machine before the current working, which represents the average oil consumption level of the working machine under the current working parameter data. During the working process of the working machine, the upper machine of the working machine can obtain the instantaneous oil consumption of the working machine in real time, and store the instantaneous oil consumption according to the working parameter data corresponding to the instantaneous oil consumption. After the current working is completed, the average value of the instantaneous oil consumption of each historical time corresponding to the working parameter data is calculated and stored as the historical average oil consumption.

[0053] The calibrated average oil consumption corresponding to the current working parameter data is a preset value. The calibrated average oil consumption corresponding to different working parameter data can be tested before the working machine is delivered, for example, the average oil consumption corresponding to different working modes and / or working gears under standard working conditions can be tested after the preheating of the working machine is completed, and the average oil consumption is set as the corresponding calibrated average oil consumption in the upper machine of the working machine.

[0054] The average fuel consumption corresponding to the last work of the current work parameter data can be the average fuel consumption corresponding to the current work parameter data in the work closest to the current work using the current work parameter data. Considering that the working conditions of the adjacent two work processes are similar, in the process of determining the current fuel consumption of the working machine based on the average fuel consumption of the last work, the influence of the working condition on the determination result of the current fuel consumption can be fully considered, and the accuracy of the determination result of the current fuel consumption is effectively improved.

[0055] The average fuel consumption corresponding to the current work of the current work parameter data can be the average value of the instantaneous fuel consumption corresponding to each time of the current work parameter data in the current work, so that in the process of determining the current fuel consumption of the working machine based on the average fuel consumption of the current work, the influence of the operation habit of the operator on the determination result of the current fuel consumption can be fully considered, and the accuracy of the determination result of the current fuel consumption is effectively improved.

[0056] The current instantaneous fuel consumption can be the instantaneous fuel consumption corresponding to the current sampling time. The instantaneous fuel consumption of each time can be collected by the lower machine of the working machine and uploaded to the upper machine in real time. Among them, the lower machine of the working machine can collect the real-time fuel consumption of the engine through CAN communication, and sample the real-time fuel consumption according to different work parameter data, for example, sample the real-time fuel consumption in units of 10 minutes, and integrate the collected real-time fuel consumption in time to obtain the instantaneous fuel consumption. The lower machine can store and upload the instantaneous fuel consumption to the upper machine, so that the determination of the current fuel consumption can be completed by the lower machine and the upper machine. Since the upper machine has large data storage space and strong computing power, the accuracy of the determination result of the current fuel consumption of the working machine can be effectively improved based on the instantaneous fuel consumption sent by the lower machine.

[0057] The current fuel consumption of the working machine can be the average fuel consumption corresponding to the current sampling time. In actual application, the upper machine of the working machine can determine one or more fuel consumption data from the historical average fuel consumption corresponding to the current work parameter data of the working machine, the calibrated average fuel consumption, the average fuel consumption of the last work, the average fuel consumption of the current work and the current instantaneous fuel consumption based on the working time and the current working state of the working machine, and use the one or more fuel consumption data as target fuel consumption data to determine the current fuel consumption of the working machine according to the target fuel consumption data. In the process of determining the current fuel consumption of the working machine, the influence of the actual working condition of the working machine, the operation habit of the operator, the equipment state of the working machine and the current working state of the working machine on the current fuel consumption of the working machine can be considered comprehensively, and the accuracy of the determination result of the current fuel consumption of the working machine is effectively improved.

[0058] The embodiment can determine the current fuel consumption of the working machine by obtaining the working time and the current working state of the working machine, and determining the current fuel consumption of the working machine based on one or more of the historical average fuel consumption, the calibrated average fuel consumption, the average fuel consumption of the last working, the average fuel consumption of the current working, and the current instantaneous fuel consumption corresponding to the current working parameter data of the working machine, and the working time and the current working state, thereby comprehensively considering the influence of the actual working condition of the working machine, the operation habit of the operator, the equipment state of the working machine, and the current working state of the working machine on the current fuel consumption of the working machine, and effectively improving the accuracy of the determination result of the current fuel consumption of the working machine.

[0059] In the example embodiment, the determination of the current fuel consumption of the working machine based on one or more of the multiple types of fuel consumption data corresponding to the current working parameter data of the working machine, and the working time and the current working state, comprises:

[0060] If the working time is less than or equal to the preset time length, and the current working state meets the preset state, the current fuel consumption of the working machine is determined based on the calibrated average fuel consumption;

[0061] If the working time is less than or equal to the preset time length, and the current working state does not meet the preset state, the current fuel consumption of the working machine is determined based on the average of the current instantaneous fuel consumption and the calibrated average fuel consumption;

[0062] If the working time is greater than the preset time length, and the current working state meets the preset state, the current fuel consumption of the working machine is determined based on the average fuel consumption of the current working and the average fuel consumption of the last working;

[0063] If the working time is greater than the preset time length, and the current working state does not meet the preset state, the current fuel consumption of the working machine is determined based on the average fuel consumption of the last working and the historical average fuel consumption.

[0064] The preset time length can be determined according to the time length of the running-in period of the working machine. If the working time is less than or equal to the preset time length, it indicates that the working machine is a new device just out of the factory, i.e., the working machine is in the running-in period. If the working time is greater than the preset time length, it indicates that the working machine has been working for a period of time, i.e., the working machine has completed the running-in. In the process of determining the current fuel consumption of the working machine, by judging whether the working time of the working machine reaches the preset time length, the influence of the unstable fuel consumption of the working machine during the running-in process of the new vehicle on the accuracy of the determination result of the current fuel consumption can be effectively avoided.

[0065] The preset state can be a preheating completion state. In the process of determining the current fuel consumption of the working machine, by judging whether the current working state of the working machine meets the preset completion state, the influence of unstable fuel consumption in the preheating process on the accuracy of the determination result of the current fuel consumption can be effectively avoided.

[0066] In actual application, if the working duration of the working machine is less than or equal to the preset duration, and the current working state of the working machine meets the preset state, the current fuel consumption of the working machine can be determined based on the calibration average fuel consumption corresponding to the current working parameter data, so that the influence of unstable fuel consumption in the initial working stage of the working machine on the accuracy of the determination result of the current fuel consumption can be effectively avoided. For example, the calibration average fuel consumption of the working machine can be directly used as the current fuel consumption of the working machine, and the calibration average fuel consumption can also be corrected according to the current instantaneous fuel consumption, for example, a correction coefficient and / or a correction value can be determined based on the current instantaneous fuel consumption, and the calibration average fuel consumption is corrected based on the correction coefficient and / or the correction value. The correction coefficient and / or the correction value can be obtained by testing the working machine of the same model under the same equipment state and working state (for example, the working duration is less than or equal to the preset duration, and the working machine is in the preheating completion state).

[0067] If the working duration of the working machine is less than or equal to the preset duration, and the current working state of the working machine does not meet the preset state, the current fuel consumption of the working machine can be determined based on the average of the current instantaneous fuel consumption and the calibration average fuel consumption corresponding to the current working parameter data, so that the influence of unstable fuel consumption in the initial working stage of the working machine and in the preheating process on the accuracy of the determination result of the current fuel consumption can be effectively avoided. Among them, the current fuel consumption of the working machine can be directly obtained by averaging the current instantaneous fuel consumption and the calibration average fuel consumption; the first weight coefficient corresponding to the current instantaneous fuel consumption can also be determined based on the first correspondence relationship between the current instantaneous fuel consumption and the first weight coefficient, and the current instantaneous fuel consumption and the calibration average fuel consumption are weighted and summed based on the first weight coefficient, so as to obtain the average of the current instantaneous fuel consumption and the calibration average fuel consumption, and the average is used as the current fuel consumption of the working machine.

[0068] If the working time of the working machine is greater than the preset time length, and the current working state of the working machine meets the preset state, the current fuel consumption of the working machine can be determined based on the average fuel consumption of the current working and the average fuel consumption of the last working corresponding to the current working parameter data. For example, the current fuel consumption of the working machine can be determined based on the difference between the average fuel consumption of the current working and the average fuel consumption of the last working, and the average fuel consumption of the current working and / or the average fuel consumption of the last working. The average of the average fuel consumption of the current working and the average fuel consumption of the last working can also be used as the current fuel consumption of the working machine. Thus, after the working machine works stably, the influence of the working condition of the working machine on the determination result of the current fuel consumption can be effectively reduced, and the accuracy of the determination result of the current fuel consumption is effectively improved.

[0069] If the working time of the working machine is greater than the preset time length, and the current working state of the working machine does not meet the preset state, the current fuel consumption of the working machine can be determined based on the average fuel consumption of the last working and the historical average fuel consumption corresponding to the current working parameter data. For example, the current fuel consumption of the working machine can be determined based on the difference between the average fuel consumption of the last working and the historical average fuel consumption, and the average fuel consumption of the last working and / or the historical average fuel consumption. The average of the average fuel consumption of the last working and the historical average fuel consumption can also be used as the current fuel consumption of the working machine. Thus, the influence of the unstable fuel consumption of the working machine during the warming-up process on the determination result of the current fuel consumption can be effectively reduced. The current fuel consumption of the working machine is determined based on the average fuel consumption of the last working and the historical average fuel consumption, which can fully consider the influence of the working condition and the average fuel consumption level of the working machine on the determination result of the current fuel consumption, and effectively improve the accuracy of the determination result of the current fuel consumption.

[0070] In an example embodiment, the current fuel consumption of the working machine is determined based on the average fuel consumption of the current working and the average fuel consumption of the last working, including:

[0071] If the difference between the average fuel consumption of the current working and the average fuel consumption of the last working is greater than a first preset difference, the current fuel consumption of the working machine is determined based on the average fuel consumption of the current working. If not, the current fuel consumption of the working machine is determined based on the average of the average fuel consumption of the current working and the average fuel consumption of the last working.

[0072] The first preset difference can be set according to actual needs, for example, it can be 10% of the average fuel consumption of the last working.

[0073] When the difference between the average fuel consumption of the current work and the average fuel consumption of the previous work is greater than the first preset difference value, it is indicated that the working condition of the current work is greatly different from the working condition of the previous work, and the average fuel consumption of the current work can be taken as the current fuel consumption of the working machine, so that the influence of the operation habit of the operator on the determination result of the current fuel consumption is fully considered, and the accuracy of the determination result of the current fuel consumption is effectively improved.

[0074] When the difference between the average fuel consumption of the current work and the average fuel consumption of the previous work is less than or equal to the first preset difference value, it is indicated that the working condition of the current work is similar to the working condition of the previous work, and the average of the average fuel consumption of the current work and the average fuel consumption of the previous work can be taken as the current fuel consumption of the working machine, so that the influence of the working condition and the operation habit of the operator on the determination result of the current fuel consumption is fully considered, and the accuracy of the determination result of the current fuel consumption is effectively improved. The second weight coefficient corresponding to the average fuel consumption of the current work can be determined based on the first difference between the average fuel consumption of the current work and the average fuel consumption of the previous work and a second correspondence relationship between the first difference and the second weight coefficient, and the average fuel consumption of the current work and the average fuel consumption of the previous work are weighted and summed based on the second weight coefficient to obtain the average of the average fuel consumption of the current work and the average fuel consumption of the previous work.

[0075] In an example embodiment, the determination of the current fuel consumption of the working machine based on the average fuel consumption of the previous work and the historical average fuel consumption comprises:

[0076] If the difference between the average fuel consumption of the previous work and the historical average fuel consumption is greater than a second preset difference value, the current fuel consumption of the working machine is determined based on the average fuel consumption of the previous work; otherwise, the current fuel consumption of the working machine is determined based on the average of the average fuel consumption of the previous work and the historical average fuel consumption.

[0077] The second preset difference value can be set according to actual needs, for example, it can be 10% of the historical average fuel consumption.

[0078] When the difference between the average fuel consumption of the previous work and the historical average fuel consumption is greater than the second preset difference value, it is indicated that the average fuel consumption of the previous work is greatly different from the historical average fuel consumption of the working machine, and the average fuel consumption of the previous work can be taken as the current fuel consumption of the working machine, so that the influence of the working condition difference on the determination result of the current fuel consumption is avoided, and the accuracy of the determination result of the current fuel consumption is effectively improved.

[0079] When the difference between the average fuel consumption of the last work and the historical average fuel consumption is less than or equal to the second preset difference, it is indicated that the average fuel consumption of the last work is close to the historical average fuel consumption of the working machine, and the average of the average fuel consumption of the last work and the historical average fuel consumption can be taken as the current fuel consumption of the working machine, so that the influence of the working condition and the historical average fuel consumption of the working machine on the accuracy of the determination result of the current fuel consumption can be fully considered, and the accuracy of the determination result of the current fuel consumption is effectively improved. Among them, the third weight coefficient corresponding to the average fuel consumption of the last work can be determined based on the second difference between the average fuel consumption of the last work and the historical average fuel consumption and the third corresponding relationship between the second difference and the third weight coefficient, and the average fuel consumption of the last work and the historical average fuel consumption are weighted and summed based on the third weight coefficient to obtain the average of the average fuel consumption of the last work and the historical average fuel consumption.

[0080] The application will be described below in conjunction with Figure 2 The remaining work duration detection method of the application is described. The remaining work duration detection method of the application is executed by hardware and / or software in the lower machine of the working machine. As shown in the Figure 2 The remaining work duration detection method of the application at least includes the following steps:

[0081] S201, obtaining the current fuel level of the working machine and the current fuel consumption of the working machine; wherein the current fuel consumption of the working machine is obtained based on the fuel consumption detection method described in any of the above embodiments, or the current fuel consumption of the working machine is determined based on the current instantaneous fuel consumption of the working machine;

[0082] S202, filtering the current fuel level, and determining the remaining fuel quantity of the working machine based on the filtering result of the current fuel level;

[0083] S203, determining the current remaining work duration of the working machine based on the remaining fuel quantity and the current fuel consumption.

[0084] In this embodiment, the current fuel level of the working machine is the liquid level height or the liquid level height ratio (the ratio of the liquid level height to the total height of the fuel tank) of the working machine at the current time, which can be collected by a liquid level sensor.

[0085] The current fuel consumption of the working machine can be the average fuel consumption corresponding to the current sampling time. The current fuel consumption of the working machine can be obtained based on the fuel consumption detection method according to any one of the above embodiments. For example, the host computer of the working machine can send the average fuel consumption corresponding to each sampling time to the lower computer in real time, so that the lower computer determines the remaining working time. Since the host computer has large data storage space and strong computing power, the determination of the current fuel consumption by the host computer can effectively improve the accuracy of the determination result of the current fuel consumption. The current fuel consumption of the working machine can also be determined based on the current instantaneous fuel consumption of the working machine, so that the real-time detection of the remaining working time of the working machine can still be realized when the communication between the host computer and the lower computer is abnormal. The lower computer can collect the real-time fuel consumption of the engine through CAN communication, and sample the real-time fuel consumption according to different working parameter data, for example, sample the real-time fuel consumption in units of 10 minutes, and integrate the collected real-time fuel consumption in time to obtain the instantaneous fuel consumption. The instantaneous fuel consumption is stored and uploaded to the host computer. As an optional implementation, the lower computer can monitor the communication state with the host computer. If the communication state is normal, the current fuel consumption sent by the host computer is received. If the communication state is abnormal, the current instantaneous fuel consumption is used as the current fuel consumption.

[0086] When the current fuel level of the working machine is obtained, the current fuel level can be filtered, and the remaining fuel quantity of the working machine is determined based on the result of the filtering of the current fuel level. For example, the remaining fuel quantity of the working machine can be determined based on the result of the filtering of the current fuel level and the size of the fuel tank of the working machine. The specific way of filtering the fuel level can be set according to actual needs. For example, the collected current fuel level can be filtered by a pre-set filter to avoid the influence of various interference factors in the data collection process on the accuracy of the collected result of the current fuel level. The collected current fuel level can also be filtered based on a pre-set range corresponding to the change amount of the liquid level to avoid the influence of the liquid level fluctuation during the working process of the working machine on the accuracy of the collected result of the current fuel level.

[0087] The current remaining working time is the working time at the current time. The ratio of the remaining fuel quantity to the current fuel consumption can be used as the current remaining working time of the working machine. After determining the current remaining working time, the lower computer can upload the current remaining working time to the host computer in real time. The current fuel consumption and the current remaining working time can also be displayed through the display device of the working machine, so that the user can view the current fuel consumption and the current remaining working time of the working machine in real time.

[0088] The existing remaining working time detection method is usually used in the traditional automobile or electric industry and cannot be applied to working machines with complex working conditions. The embodiment obtains the current fuel consumption of the working machine determined by the upper computer, and obtains the current fuel level of the working machine. The remaining fuel amount of the working machine is determined based on the filtering processing result of the current fuel level. The current remaining working time of the working machine is determined based on the remaining fuel amount and the current fuel consumption, which can effectively ensure the accuracy of the determination result of the remaining working time of the working machine. At the same time, when the current fuel consumption sent by the upper computer cannot be obtained, the current fuel consumption of the working machine can also be determined based on the current instantaneous fuel consumption of the working machine, so that the real-time detection of the remaining working time of the working machine can be realized.

[0089] In the example embodiment, the filtering processing on the current fuel level comprises:

[0090] Based on the comparison result of the first liquid level change amount corresponding to the current fuel level and the preset range, it is determined whether to trigger the filtering timing;

[0091] If the filtering timing is triggered, the comparison result of the second liquid level change amount corresponding to the fuel level at the filtering timing arrival time and the preset range is used to determine the filtering processing result of the current fuel level;

[0092] If the filtering timing is not triggered, the filtering processing result of the current fuel level is determined based on the current fuel level.

[0093] In the embodiment, the first liquid level change amount corresponding to the current fuel level can be the absolute value of the difference between the current fuel level and the fuel level collected at the last time. The second liquid level change amount corresponding to the fuel level at the filtering timing arrival time can be the absolute value of the difference between the fuel level at the filtering timing arrival time and the current fuel level. The preset range can be a threshold range corresponding to the liquid level change amount, which can include a lower threshold and an upper threshold.

[0094] When filtering the current fuel level, the comparison result of the first liquid level change amount corresponding to the current fuel level and the preset range can be used to determine whether to trigger the filtering timing.

[0095] If the first liquid level change amount exceeds the preset range, for example, the first liquid level change amount is greater than the upper threshold or less than the lower threshold, it indicates that there is liquid level shaking and the current fuel level is at risk of inaccuracy. The filtering timing can be triggered, and the comparison result of the second liquid level change amount corresponding to the fuel level at the filtering timing arrival time and the preset range is used to determine the filtering processing result of the current fuel level.

[0096] If the first liquid level change amount does not exceed the preset range, for example, the first liquid level change amount is less than or equal to the upper threshold and greater than or equal to the lower threshold, it indicates that the accuracy of the current fuel level meets the requirements, and the collected current fuel level can be directly used as the result of the filtering processing of the current fuel level.

[0097] Due to the large shaking during the working process of the working machine, the filtering processing of the current fuel level by the method of the embodiment can effectively reduce the influence of the liquid level shaking on the accuracy of the current fuel level during the working process of the working machine, and further improve the accuracy of the determination result of the current remaining working time.

[0098] In an example embodiment, the comparison result of the second liquid level change amount corresponding to the fuel level at the filtering timing arrival time and the preset range is used to determine the result of the filtering processing of the current fuel level, including:

[0099] If the second liquid level change amount meets the preset range, the current fuel level is used as the result of the filtering processing of the current fuel level; if not, the result of the filtering processing of the fuel level at the last time is used as the result of the filtering processing of the current fuel level.

[0100] In the embodiment, if the second liquid level change amount corresponding to the fuel level at the filtering timing arrival time meets the preset range, it indicates that there is no obvious fluctuation of the liquid level within the filtering time, and the accuracy of the current fuel level meets the requirements, and the collected current fuel level can be used as the result of the filtering processing of the current fuel level.

[0101] If the second liquid level change amount corresponding to the fuel level at the filtering timing arrival time cannot meet the preset range, it indicates that the accuracy of the current fuel level cannot meet the requirements, or the fuel level is still in the state of shaking, and the result of the filtering processing of the fuel level at the last time can be used as the result of the filtering processing of the current fuel level. It should be noted that the last time here refers to the time of the current fuel level, so as to effectively reduce the influence of the liquid level shaking on the accuracy of the current fuel level during the working process of the working machine, and further improve the accuracy of the determination result of the current remaining working time.

[0102] In an example embodiment, the determination of the remaining fuel amount of the working machine based on the result of the filtering processing of the current fuel level includes:

[0103] The current inclination angle of the fuel tank of the working machine is obtained.

[0104] The remaining fuel amount of the working machine is determined based on the result of the filtering processing of the current fuel level, the current inclination angle, and the size information of the fuel tank.

[0105] In this embodiment, the current inclination angle of the fuel tank of the working machine can be acquired by the inclination sensor.

[0106] In the process of determining the remaining fuel amount of the working machine, the remaining fuel amount of the working machine can be determined based on the filtered result of the current fuel level, the current inclination angle and the size information of the fuel tank. For example, the actual fuel level of the working machine can be determined based on the filtered result of the current fuel level, the current inclination angle and the size information of the fuel tank, and the remaining fuel amount of the working machine can be determined based on the actual fuel level and the size information of the fuel tank, so that the influence of the accuracy of the determination result of the remaining fuel amount when the working machine is located on the slope can be effectively avoided, and the accuracy of the determination result of the current remaining working time is improved.

[0107] Among them, the actual fuel level of the working machine can be determined by the method of the triangle theorem based on the filtered result of the current fuel level, the current inclination angle and the size information of the fuel tank.

[0108] For example, as shown in Figure 3 , the length of the fuel tank is a, the height is h, the distance from the liquid level sensor to one end of the length direction of the fuel tank is c, the current inclination angle is θ, and the filtered result of the current fuel level is P 滤波 , then when ctanθ 滤波 -ctanθ+atanθ 实际 < h, the actual fuel level P 滤波 = P 滤波 -ctanθ+a / 2tanθ; when ctanθ 滤波 -ctanθ+atanθ, or h 实际 ≤ P 滤波 -ctanθ+atanθ.
