[0029] Figure 1 The flowchart of a method for determining the pumpable volume of an electric pumping device according to an embodiment of the present application is schematically shown. Figure 1 As shown, the embodiment of the present application provides a method for determining the pumpable volume of an electric pumping device, which is described by taking the application of the method and a processor as an example. The method may include the following steps:

[0030] Step S102, obtaining the current remaining power, current pumping pressure, historical average volumetric power consumption and historical average pumping pressure of the electric pumping equipment.

[0031] Step S104, determining a pumping pressure weighting coefficient according to the current pumping pressure and the historical average pumping pressure.

[0033] Step S108, determining the pumpable volume of the electric pumping equipment according to the current remaining power and the current volume power consumption.

[0034] It can be understood that the electric pumping equipment may include, for example, an electric pump truck, etc. The current remaining power of the electric pumping equipment is the current available power of the electric pumping equipment, which can be directly obtained through the battery management system, or calculated through relevant data such as current and voltage collected in real time by the data acquisition module. The current pumping pressure of the electric pumping equipment is the pumping pressure of the electric pumping equipment under the current pumping construction condition, for example, it can be the working pressure of a hydraulic pump or an electric pump, which can be obtained in real time through the data acquisition module. The historical average volume power consumption of the electric pumping equipment is the average value of the historical pumping volume power consumption of the electric pumping equipment, which can be the average value of the historical pumping volume power consumption in the past period of time, or the average value of the historical pumping volume power consumption of multiple pumping constructions in the past. It can be obtained by direct input by the user, or it can be calculated and stored by the processor in advance based on the historical pumping volume data and historical power consumption data. The historical average pumping pressure is the average value of the historical pumping pressure of the electric pumping equipment. It can be the average value of the historical pumping pressure in the past period of time, or the average value of the historical pumping pressure of multiple pumping constructions in the past. It can be obtained by direct input by the user, or it can be calculated and stored by the processor in advance based on the historical pumping pressure data. The pumping pressure weighting coefficient is a coefficient that characterizes the influence of the pumping pressure on the volume power consumption. The current volume power consumption is the pumping volume power consumption corresponding to the current pumping construction condition, that is, the amount of electricity consumed for each pumping volume under the current pumping construction condition. The pumpable volume of the electric pumping equipment is the remaining pumping volume of the electric pumping equipment.

[0035] Specifically, the processor can obtain the current remaining power, current pumping pressure, historical average volume power consumption and historical average pumping pressure of the electric pumping equipment, and then determine the pumping pressure weighting coefficient according to the current pumping pressure and the historical average pumping pressure, so that the historical average volume power consumption can be corrected according to the pumping pressure weighting coefficient to obtain the current volume power consumption, and the pumpable volume of the electric pumping equipment can be determined according to the current remaining power and the current volume power consumption. For example, after obtaining the current remaining power, current pumping pressure, historical average volume power consumption and historical average pumping pressure of the electric pumping equipment, the processor can determine the ratio of the historical average pumping pressure to the current pumping pressure to obtain the pumping pressure weighting coefficient, and then determine the ratio of the historical average volume power consumption to the pumping pressure weighting coefficient to correct the historical average volume power consumption to obtain the current volume power consumption corresponding to the current pumping construction condition, and then determine the ratio of the current remaining power to the current volume power consumption to obtain the pumpable volume of the electric pumping equipment.

The above technical scheme takes into account the influence of the pumping pressure on the volume power consumption of the current pumping construction condition, determines the pumping pressure weighting coefficient based on the current pumping pressure and the historical average pumping pressure, and then corrects the historical average volume power consumption according to the pumping pressure weighting coefficient to obtain the current volume power consumption corresponding to the current pumping condition, thereby improving the accuracy of the volume power consumption, thereby accurately determining the pumpable volume of the electric pumping equipment, and also improving the applicability of the electric pumping equipment to different pumping construction conditions, avoiding the inability to construct due to power exhaustion.

[0037] In one embodiment, determining the pumping pressure weighting coefficient according to the current pumping pressure and the historical average pumping pressure includes: determining the ratio of the current pumping pressure to the historical average pumping pressure to obtain the pumping pressure weighting coefficient.

[0038] Specifically, the processor may determine a ratio of the current pumping pressure to the historical average pumping pressure to obtain a pumping pressure weighting coefficient.

[0039] In one embodiment, the historical average volume power consumption is corrected according to the pumping pressure weighting coefficient to obtain the current volume power consumption, including: determining the product value of the pumping pressure weighting coefficient and the historical average volume power consumption to obtain the current volume power consumption.

[0040] Specifically, when the pumping pressure weighting coefficient is the ratio of the current pumping pressure to the historical average pumping pressure, the processor may determine the product of the pumping pressure weighting coefficient and the historical average volume power consumption to obtain the current volume power consumption.

[0041] In one embodiment, the pumpable volume of the electric pumping device is determined based on the current remaining power and the current volume power consumption, including: determining the ratio of the current remaining power to the current volume power consumption to obtain the pumpable volume of the electric pumping device.

[0043] In one embodiment, obtaining the historical average volume power consumption includes: obtaining the historical volume power consumption corresponding to each historical pumping volume of the electric pumping equipment during the pumping operation, wherein the number of historical pumping volumes is a preset pumping volume number; averaging multiple historical volume power consumptions to obtain the historical average volume power consumption.

[0044] It can be understood that the historical volume power consumption corresponding to each historical pumping volume is the power consumed for each pumping volume in the past, which can be obtained from the power data stored in the battery management system. The preset pumping volume quantity is the preset number of pumping volumes, such as 100 or 80.

[0045] Specifically, the processor can obtain the historical volume power consumption corresponding to each historical pumping volume when the electric pumping equipment is performing a pumping operation, and average the historical volume power consumption of a preset number of pumping volumes to obtain the historical average volume power consumption.

[0046] In one embodiment, obtaining the historical average volume power consumption includes: obtaining the total historical pumping volume and total historical power consumption of the electric pumping equipment when performing pumping operations; determining the ratio of the total historical power consumption to the total historical pumping volume to obtain the historical average volume power consumption.

[0047] It can be understood that the total historical pumping volume is the total volume pumped by the electric pumping device in the past when performing pumping operations, which can be stored in advance. The total historical power consumption is the total power consumed by the electric pumping device in the past when performing pumping operations, which can be obtained from the data stored in the battery management system.

[0048] Specifically, the processor can obtain the total historical pumping volume and the total historical power consumption of the electric pumping equipment when performing pumping operations, and determine the ratio of the total historical power consumption to the total historical pumping volume to obtain the historical average volume power consumption.

[0049] In one embodiment, obtaining the historical average pumping pressure includes: obtaining the historical pumping pressure corresponding to each historical pumping volume of the electric pumping equipment when performing a pumping operation, wherein the number of historical pumping volumes is a preset number of pumping volumes; averaging multiple historical pumping pressures to obtain the historical average pumping pressure.

[0050] It can be understood that the historical pumping pressure corresponding to each historical pumping volume is the pumping pressure corresponding to each pumping volume in the past, for example, which can be obtained from the historical pressure data collected by the data acquisition module. The preset pumping volume quantity is the preset number of pumping volumes, such as 100 or 80.

[0051] Specifically, the processor can obtain the historical pumping pressure corresponding to each historical pumping volume when the electric pumping equipment performs a pumping operation, and average the historical pumping pressures corresponding to a preset number of historical pumping volumes to obtain a historical average pumping pressure.

[0052] In a specific embodiment, the electric pumping equipment is taken as an electric pump truck for example. Since the pure electric pump truck is used for construction at different construction sites each time and the construction site has different requirements for concrete grades, the volume of electricity consumption varies greatly. The deviation between the calculated remaining pumping volume and the actual pumpable volume will be very large, which will mislead the operator's judgment on the current remaining pumping volume of the electric pump truck and affect the construction progress of the construction site.

[0053] Figure 2 The following schematically shows a block diagram of a power system of an electric pump truck according to an embodiment of the present application. Figure 2 As shown, the power system of the electric pump truck mainly includes a power battery, a high-voltage distribution box, a superstructure motor system and a chassis drive motor system.

[0054] It is understandable that the electric pump truck can use a motor to drive the hydraulic pump during operation. The calculation formula of the operating power of the electric pump truck can be shown as follows (1):

[0055]

[0056] Among them, P 泵送 is the pumping power, P 电池 is the battery discharge power, η 电池 is the battery discharge efficiency, η 电机系统 is the motor system efficiency, p is the hydraulic pump delivery pressure, V is the hydraulic pump displacement, n is the hydraulic pump speed, η mis the total efficiency of the hydraulic pump. The displacement V and speed n are controlled by the operator's remote control in real time, and the hydraulic pump's pumping pressure p is mainly affected by the concrete grade and pumping conditions of different construction sites. According to the actual test results, the pumping pressure has a greater impact on the power consumption of the square meter, that is, the greater the hydraulic pump's pumping pressure p, the higher the pumping power P. 泵送 The larger the value, the greater the actual cubic meter power consumption corresponding to the current pumping condition.

[0057] Figure 3 The following schematically shows a block diagram of a pumpable volume management system for an electric pump truck according to an embodiment of the present application. Figure 3 As shown, the pumpable volume management system of the electric pump truck includes a body data acquisition module, a body controller, a battery management system, a body operation information display module and a chassis controller. The chassis controller can transfer battery-related information to the body controller. The body data acquisition module can obtain in real time the hydraulic pump working pressure, battery output power, battery remaining power, pump truck current working volume, and pump truck current working time during the electric pump truck body operation. The battery management system can be used to feedback the real-time remaining battery power to the body controller. The body controller can be used to calculate the current remaining pumping volume, historical volume power consumption, and historical average pumping pressure. The body operation information display module can be used to display the current remaining pumping volume.

[0058] Figure 4 A schematic diagram of a flow chart of another method for determining the pumpable volume of an electric pumping device according to an embodiment of the present application is shown schematically.

[0066] T i =t i+1 -t i (5)

[0067] When calculating q1, that is, c2-c1=1, the time difference T1=t2-t1 corresponding to the square difference of 1 collected by the upper data acquisition module, that is, t2 is the time when the upper controller records c2=1, and t1 is the time when the upper controller records c1=0. Substituting into formula (4), q1 can be calculated. According to the above method, the upper controller calculates q2 to q in real time. 100 And save it in the upper controller, so as to calculate q ave , and update q in real time according to the continuous progress of the upper pumping operation ave .

[0068] λ is the pumping pressure weighting coefficient:

[0069]

[0070] Where p is the current pumping pressure, which is collected in real time by the upper data acquisition module. ave It is the average pumping pressure of 100 cubic meters before the current construction.

[0071]

[0072] When calculating q1 using equation (4), substitute c1, c2, and T1 into equation (8) and calculate p1 synchronously. According to the above method, the upper controller calculates p2 to p1 in real time. 100 And save it in the upper controller, so as to calculate p ave , and update p in real time according to the continuous progress of the upper pumping operation ave .

[0073] According to the above calculation, p ave ,q ave and real-time collected p and Q, C can be calculated according to formula (2): end .

[0074] At this time, the loading operation information display module can display "C end square".

[0075] The above technical scheme, through the collaboration of various modules, calculates and analyzes the data collected from the battery and the upper installation operation information in real time; introduces the pumping pressure weighting coefficient to calculate the current remaining pumping volume, which can effectively improve the calculation accuracy; collects the current operation information of the battery and the upper installation and the historical data saved by the upper installation controller in real time through the upper installation data acquisition module for continuous calculation and update, and calculates the volume power consumption, pumping pressure, average volume power consumption per 100 cubic meters, average pumping pressure per 100 cubic meters and pumping pressure weighting coefficient in real time, and displays the calculation results on the display module, so that the operator can know the current remaining pumpable volume of the equipment.

[0076] This solution collects real-time information such as the battery current, voltage, power, pumping volume, and pumping pressure of the pure electric pump truck, calculates the power consumption and pumping pressure for each cubic meter pumped, and accumulates the average power consumption and pumping pressure for every 100 cubic meters worked and updates them in real time over time, reflecting the actual working conditions of the pump truck during long-term operation; a pumping pressure weighting coefficient is proposed to respond to the actual pumping conditions of different construction sites, and the remaining pumping volume is evaluated with higher accuracy through the comprehensive evaluation of the pumping pressure coefficient and the average power consumption; this solution calculates the remaining battery power, the average power consumption per 100 cubic meters, and the weighted coefficient of the pumping pressure, and displays the remaining pumpable volume to the operator in real time through the remaining pumping volume management system.
