[0036] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments.

[0037] In order to better describe the electric upper mounting control method, device, equipment and medium of a concrete mixer truck according to the embodiment of the present invention, an electric upper mounting system of a concrete mixer truck is proposed here. Figure 1The electric upper system of the concrete mixer truck includes a power battery 110, a control unit 120, and an electric drive assembly 130, a battery charging device 140, a battery management system 150, a power generation system 160, and a human-computer interaction unit 170, all of which are connected to the control unit 120. The electric drive assembly 130 is used to drive the mixing tank to rotate, the battery charging device 140 is used to charge the power battery 110, the power generation system 160 is used to provide a charging power source for the power battery 110, and the battery management system 150 is used to obtain battery status information of the power battery 110; the power battery 110 is used to provide power for the electric drive assembly 130; the control unit 120 is also used to connect to the engine of the concrete mixer truck, and the engine is used to provide a power source for the power generation system 160.

[0038] The above engine is the main engine of the mixer truck, and the main engine is used to drive the mixer truck to move.

[0039] The power generation system 160 may be a generator, which may utilize an engine as a power source to generate electricity when it is necessary to generate electricity.

[0040] The above-mentioned electric drive component 130 may include a motor driver and a drive motor. The power source of the drive motor is provided by the power battery 110. The control unit 120 controls the output state of the drive motor through the motor driver, and then drives the reducer to operate through the drive motor, thereby using the reducer to drive the mixing tank of the mixer truck to rotate.

[0041] The power battery 110 may be charged using electricity generated by the generator.

[0042] The battery charging device 140 can control the power battery 110 to perform charging operations, and the power source for charging the power battery 110 is provided by the generator.

[0043] The battery management system 150 may be a BMS system provided by the power battery 110 when it leaves the factory, and the battery management may be implemented through the battery management system 150. The control unit 120 may obtain battery status information by communicating with the BMS system.

[0044] The above-mentioned battery status information may include battery remaining power information, battery capacity information, battery charging and discharging status, charging and discharging time, etc.

For example, in addition to the conventional cab operating panel, operating panels can also be set on both sides of the parking space to facilitate operation during loading and unloading conditions.

[0049] See also Figure 2 As shown, Figure 2 1 is a flow chart of a method for controlling an electric upper part of a concrete mixer truck provided by an embodiment of the present application. The method for controlling an electric upper part of a concrete mixer truck comprises steps S110 to S140:

[0050] Step S110, obtaining the working conditions of the mixer truck in the previous stage, which include loading conditions, transporting conditions, waiting for unloading conditions, unloading conditions and return conditions;

[0051] Step S120, determining the working condition of the mixer truck in the current stage to be executed according to the working condition of the mixer truck in the previous stage, the driving state of the mixer truck and the weight information of the concrete in the mixing tank, wherein the unloading working condition is determined to be entered by the human-computer interaction unit 170;

[0052] Step S130, obtaining battery status information of the power battery 110;

[0053] Step S140 , adjusting the rotation state of the mixing tank and performing charging and discharging operations on the power battery 110 according to the working condition of the mixer truck and the battery status information of the current stage to be executed.

[0054] In the embodiment of the present application, by obtaining the working condition of the mixer truck in the previous stage, the weight information of the concrete in the mixing tank, and the working state of the engine, the working condition of the mixer truck can be automatically and quickly determined, and then the rotation control of the mixing tank and the charge and discharge control of the power battery 110 can be automatically realized on the basis of further obtaining the current battery status information. The embodiment of the present application improves the intelligence level of the electric upper part of the mixer truck by automatically determining the working condition of the mixer truck and automatically stirring the mixing tank and charging and discharging the power battery 110 under the corresponding working condition, thereby reducing the difficulty of operating the tank truck and reducing the requirements for the operator, and is suitable for industrial promotion.

[0055] Each of the above-mentioned mixer truck working conditions will be recorded after execution, so that when the mixer truck working condition of the current stage to be executed needs to be determined, the mixer truck working condition of the previous stage can be obtained. Among them, the sign of completion of each stage can be generated by manual confirmation, or it can be automatically judged according to the state of the mixer truck. For example, in the loading condition, the vehicle changes from a stationary state to a driving state, which can be determined to have completed the loading condition. In the material transporting condition, the vehicle changes from a driving state to a stationary state and lasts for a certain period of time, which can be determined to have exited the material transporting condition. In the unloading condition, it can be determined that the unloading condition has ended when the weight of the concrete in the mixing tank no longer changes. In the return condition, it can be determined that the return condition has been completed when the weight of the concrete in the mixing tank increases. In addition, all working conditions can be set to manual entry mode according to needs, so that when the model automatically recognizes errors, human intervention can be performed to avoid casualties and property losses.

[0056] The above-mentioned loading condition is the condition of adding concrete into the mixing tank of the mixer truck.

[0057] The above-mentioned material transportation condition is the condition in which a mixer truck transports concrete from a concrete production site to a use site.

[0058] The above-mentioned waiting unloading condition corresponds to the waiting condition after the mixer truck arrives at the place of use and before formal unloading.

[0059] The above-mentioned unloading working condition is the working condition of unloading the concrete in the mixing tank of the mixer truck.

[0060] The above-mentioned return condition is the condition in which the concrete in the mixing tank of the mixer truck is unloaded and returns to the production site.

[0061] The driving state of the above-mentioned mixer truck is used to reflect whether the mixer truck is in the driving process, and can be determined by factors such as the starting state of the mixer truck engine, the engagement state of the main clutch, and the change in the mileage of the mixer truck.

[0062] The weight information of the concrete in the mixing tank can be directly detected by a weight sensor installed on the mixing truck, or can be indirectly calculated by the change in current when the mixing tank is driven to rotate.

[0063] When the above-mentioned working condition of the mixer truck is determined, the driving status can be used to determine whether the vehicle is moving, and the specific working condition can be locked for the first time. The change in the weight of the concrete in the mixing tank can be used to determine whether the vehicle is unloaded and complete the second lock. Then, by confirming the working condition of the mixer truck in the previous stage, the automatic and accurate confirmation of the working condition of the mixer truck in the current stage to be executed can be achieved.

[0064] The battery status information may mainly utilize the remaining power information and the battery capacity information. The remaining power information may be used to indicate whether charging is to be performed, and the battery capacity information may indicate the frequency of the generator start-stop control.

[0065] The above-mentioned adjustment of the rotation state of the mixing tank and the charging and discharging operations on the power battery 110 according to the working condition of the mixer truck and the battery status information of the current execution stage mainly rely on the different mixing requirements of the mixing tank corresponding to each working condition to adjust the rotation speed of the mixing tank so as to achieve the purpose of non-solidification of concrete throughout the whole process. At the same time, it is necessary to combine the characteristics of the working conditions of the mixer truck in each stage, and under the premise of not affecting the main functions, to the greatest extent possible, increase the remaining power of the power battery 110 and improve the stability and reliability of the entire electric control process.

[0066] In some embodiments, the mixer truck operating condition of the current stage to be executed is determined according to the mixer truck operating condition of the previous stage, the driving state of the mixer truck, and the weight information of the concrete in the mixing tank, including:

[0067] When the mixer truck operating condition in the previous stage is the return condition, the mixer truck is in a non-driving state for a period exceeding the preset first waiting period, and the weight information of the concrete in the mixing tank indicates that the concrete has increased, it is determined that the mixer truck operating condition in the current stage to be executed is the loading condition;

[0068] When the mixer truck operating condition in the previous stage is the loading condition, the mixer truck is in the driving state, and the weight information of the concrete in the mixing tank does not increase within the preset second waiting time, it is determined that the mixer truck operating condition in the current stage to be executed is the transporting condition;

[0069] When the mixer truck operating condition in the previous stage is the material transporting condition, the mixer truck is in a non-driving state for a period exceeding the preset third waiting period, and the weight information of the concrete in the mixing tank indicates that the weight of the concrete has not changed, it is determined that the mixer truck operating condition in the current stage to be executed is the waiting unloading condition;

[0070] In response to the unloading confirmation operation executed on the human-machine interaction unit 170, determining that the mixer truck operating condition of the current stage to be executed is the unloading operating condition;

[0071] When the operating condition of the mixer truck in the previous stage is the unloading condition, the mixer truck is in the driving state, and the weight information of the concrete in the mixing tank indicates that the concrete weight is less than or equal to the preset empty weight, it is determined that the operating condition of the mixer truck in the current stage to be executed is the return condition.

[0072] In the above-mentioned loading operating scenario, the mixer truck must be in a stopped state. In order to avoid wrong judgment, a preset first waiting time is set. At the same time, during the loading stage, the weight of concrete will inevitably increase. The mixer truck operating condition in the previous stage is further used as the basis for judgment, so as to accurately determine whether the current condition is loading.

[0073] The above-mentioned stop state can be determined by judging whether the engine is turned off, whether the mileage changes, whether the main clutch is engaged, etc.

[0074] In the above-mentioned material transport operating scenario, the mixer truck must be in a driving state. At the same time, the weight of the concrete will not change during the transportation stage. In order to avoid wrong judgment, a preset second waiting time is set, that is, there is no weight increase for at least the preset second waiting time, and then the mixer truck operating condition in the previous stage is further used as the basis for judgment, so as to accurately determine whether the current condition is material transport.

[0075] Whether the above-mentioned mixer truck is in a driving state can be confirmed by directly determining whether the mileage changes, and the judgment can be completed by combining the operating state of the engine and whether the main clutch controlling the travel is engaged. There are many specific ways to determine whether it is in a driving state, which are not specifically limited in this embodiment.

[0076] In the above-mentioned waiting for unloading operating condition scenario, the mixer truck must be in a stopped state. In order to avoid wrong judgment, a preset third waiting time is set. At the same time, during the waiting for unloading stage, the weight of the concrete will not change significantly. The mixer truck operating condition in the previous stage is further used as the basis for judgment, so as to accurately determine whether the current condition is unloading.

[0077] The above-mentioned unloading condition involves material unloading. In order to improve safety, manual operation is selected in the implementation mode of the present application.

[0078] In the above-mentioned return operating scenario, the mixer truck must be in a driving state. At the same time, during the return stage, the weight of the concrete in the mixing tank should not be higher than the preset empty weight. The mixer truck operating condition in the previous stage is further used as the basis for judgment, so as to accurately determine whether the current condition is unloading.

[0079] The above-mentioned preset empty-load weight varies according to the sizes of different concrete mixer trucks, and the specific size can be adaptively adjusted according to different models of concrete mixer trucks before leaving the factory.

[0080] In some embodiments, according to the working condition of the mixer truck and the battery status information of the current stage to be executed, the rotation state of the mixing tank is adjusted, and the charging and discharging operations are performed on the power battery 110, including:

[0081] When the current execution phase is the loading condition, the loading control strategy is executed;

[0082] Charge control strategies, including:

[0083] When the battery status information indicates that the remaining power of the power battery 110 is greater than a preset startup safety threshold, the mixing tank is controlled to rotate so that the concrete in the mixing tank does not solidify;

[0084] When the battery status information indicates that the remaining power of the power battery 110 is less than a preset forced charging safety threshold, the power generation system 160 is started, and the power generation system 160 is used to charge the power battery 110; wherein the preset start-up safety threshold is greater than the preset forced charging safety threshold;

[0085] Control the auxiliary electrical equipment in the mixer truck to shut down.

[0086] In this embodiment, considering that the mixer truck adopts an electric loading system, it is necessary to better control the charge and discharge of the power battery 110 so that the power battery 110 can be in a high power state as much as possible; and in order to avoid the situation where the truck starts even when the power is low, a preset startup safety threshold is set to avoid high power consumption during the startup phase, which may lead to a decrease in the performance of the power battery 110. At the same time, in order to save power consumption, all auxiliary power-consuming equipment is turned off during the loading phase.

[0087] The above-mentioned auxiliary electrical equipment may include air conditioners, lighting fixtures, etc.

[0088] The above-mentioned preset startup safety threshold can be 40% of the remaining power, and the specific size can be adaptively adjusted according to the actual situation.

[0089] The above preset forced charging safety threshold is 15% of the remaining power, and the specific value is adaptively adjusted according to the actual situation.

[0090] During the above-mentioned loading process, the power battery 110 can execute the charging logic all the time after starting, or set a preset high threshold of power. When the remaining power of the power battery 110 is full, the charging is stopped, and when the power is lower than the preset high threshold, the charging is continued without waiting until the power battery 110 reaches the preset forced charging safety threshold.

[0091] During the above-mentioned loading process, the stirring tank can be controlled to rotate at 1.5 rpm to 2 rpm, and the specific rotation speed can be adjusted according to actual conditions.

[0096] Control the rotation of the mixing tank so that the concrete in the mixing tank does not solidify.

[0097] In this embodiment, considering that the mixer truck adopts an electric upper loading system, it is necessary to better control the charge and discharge of the power battery 110 so that the power battery 110 can be in a high power state as much as possible. At the same time, considering that the primary task of the transportation stage is to transport concrete, the time slot brought by active speed reduction operations such as braking can be used for supplementary charging. Moreover, because the speed reduction operation is performed, the engine power is used to drive the power generation system 160 to generate electricity, which can not only ensure the speed reduction effect, but also realize kinetic energy recovery and avoid energy waste.

[0098] The above-mentioned preset high threshold of power can be 95% of the remaining power, and the specific size is adaptively adjusted according to the actual situation.

[0099] During the above-mentioned material transport process, the stirring tank can be controlled to rotate at 0.8rpm to 1.2rpm, and the specific rotation speed can be adjusted according to actual conditions.

[0100] In some embodiments, according to the working condition of the mixer truck and the battery status information of the current stage to be executed, the rotation state of the mixing tank is adjusted, and the charging and discharging operations are performed on the power battery 110, including:

[0101] When the current execution stage is the waiting unloading condition, the waiting unloading control strategy is executed;

[0105] Control the auxiliary electrical equipment in the mixer truck to shut down.

[0106] In this embodiment, considering that the mixer truck adopts an electric loading system, it is necessary to better control the charge and discharge of the power battery 110 so that the power battery 110 can be in a high power state as much as possible; and in order to avoid frequent start and stop of the power generation system 160 during the waiting process, charging is considered only when it is lower than the preset mandatory charging safety threshold. At the same time, in order to save power consumption, all auxiliary power equipment is turned off during the loading stage.

[0107] The above-mentioned auxiliary electrical equipment may include air conditioners, lighting fixtures, etc.

[0108] The above preset forced charging safety threshold is 15% of the remaining power, and the specific value is adaptively adjusted according to the actual situation.

[0109] During the above-mentioned waiting for unloading condition, the stirring tank can be controlled to rotate at 0.8rpm to 1.2rpm, and the specific rotation speed can be adjusted according to the actual situation.

[0116] In this embodiment, considering that the mixer truck adopts an electric loading system, it is necessary to better control the charge and discharge of the power battery 110 so that the power battery 110 can be in a high power state as much as possible. At the same time, considering that the primary task of the unloading stage is to complete the unloading of concrete, charging is considered only when it is lower than the preset mandatory charging safety threshold.

[0125] In this embodiment, considering that the mixer truck adopts an electric upper loading system, it is necessary to better control the charge and discharge of the power battery 110 so that the power battery 110 can be in a high power state as much as possible. At the same time, considering that the primary task in the return stage is to consider the driving of the vehicle, it is necessary to use the time slot brought by the active deceleration operation such as braking for timely charging, and because the deceleration operation is performed, the engine power is used to drive the power generation system 160 to generate electricity, which can not only ensure the deceleration effect, but also realize kinetic energy recovery and avoid energy waste.

[0126] The above-mentioned preset high threshold of power can be 95% of the remaining power, and the specific size is adaptively adjusted according to the actual situation.

[0127] In some embodiments, the electric upper part control method of a concrete mixer truck further includes:

[0128] Obtaining the real-time speed of the engine, the real-time speed of the mixing tank, the mileage of the mixing truck, and the battery capacity of the power battery 110;

[0129] The real-time speed of the engine, the real-time speed of the mixing tank, the mileage of the mixer truck, and the battery capacity of the power battery 110 are input into a pre-built fuel consumption confirmation model corresponding to the current execution phase to obtain the current fuel consumption index; wherein each mixer truck working condition corresponds to a different fuel consumption confirmation model;

[0130] Obtain the last fuel consumption index corresponding to the mixer truck working condition of the current execution stage;

[0131] When the last fuel consumption index is better than the current fuel consumption index, the engine speed and the mixing tank speed are adjusted to the engine speed and the mixing tank speed corresponding to the last fuel consumption index;

[0132] When the current fuel consumption index is better than the previous fuel consumption index, the engine speed and the mixing tank speed corresponding to the current fuel consumption index are maintained, and the fuel consumption confirmation model is updated.

[0133] In this implementation, the current fuel consumption index is compared with the previous fuel consumption index to determine whether the currently executed engine speed control and mixing tank speed control are in a more optimal state. Then, when they are in a more optimal state, the control can be completed with the engine speed and mixing tank speed corresponding to the current fuel consumption index, and the fuel consumption confirmation model can be optimized. At the same time, when they are not in a more optimal state, the engine speed and mixing tank speed corresponding to the previous fuel consumption index are still used for control to reduce the overall fuel consumption of the mixer truck as much as possible.

[0134] The above fuel consumption confirmation model is independently set for each mixer truck operating condition, so that each operating condition can be better optimized, and the impact of differences between operating conditions on the fuel consumption evaluation results can be avoided.

[0135] In some implementations, each fuel consumption validation model is constrained by the following formula:

[0136] ;

[0137] In the formula, is the fuel consumption indicator, is the real-time engine speed, is the real-time speed of the mixing tank, is the mileage of the mixer truck, is the battery capacity of the power battery 110, is the first weight coefficient corresponding to the real-time speed of the engine, is the second weight coefficient corresponding to the real-time speed of the mixing tank, is the third weight coefficient corresponding to the mileage of the mixer truck, is a fourth weight coefficient corresponding to the battery capacity of the power battery 110; the sum of the first weight coefficient, the second weight coefficient, the third weight coefficient and the fourth weight coefficient is 1; wherein the third weight coefficient and the fourth weight coefficient are both preset constants;

[0138] Updated fuel consumption confirmation model, including:

[0139] Determining a first fuel consumption change influencing parameter according to the real-time speed of the engine corresponding to the current fuel consumption index and the real-time speed of the engine corresponding to the previous fuel consumption index;

[0140] Determine a second fuel consumption change influencing parameter according to the real-time speed of the mixing tank corresponding to the current fuel consumption index and the real-time speed of the mixing tank corresponding to the previous fuel consumption index;

[0141] The first weight coefficient and the second weight coefficient are updated according to the first fuel consumption change influencing parameter and the second fuel consumption change influencing parameter, and the current fuel consumption index is updated using the first weight coefficient and the second weight coefficient.

[0142] In this embodiment, considering that the change in fuel consumption is mainly affected by the engine speed and the mixing tank speed of the mixer truck, the weight coefficients corresponding to the battery capacity and the mileage are constantized, thereby simplifying the amount of calculation in the model optimization process. In addition, because the real-time speed of the engine, the real-time speed of the mixing tank, the battery capacity and the mileage are comprehensively considered during the model construction stage, it can be ensured that in the subsequent optimization process, the influence of the battery capacity and the mileage in the optimized model can still be guaranteed, so that the entire fuel consumption confirmation model can be better adapted to the mixer truck with an electric upper system.

[0143] The real-time speed of the above-mentioned engine and the real-time speed of the mixing tank have opposite changing trends, that is, the speed of the mixing tank decreases as the engine speed increases, so that the overall fuel consumption can be better controlled. In addition, there are different minimum requirements for the speed of the mixing tank at different stages, and it is necessary to avoid the speed of the mixing tank from decreasing below the preset minimum speed.

[0144] The above-mentioned corresponding relationship between the real-time speed and fuel consumption of the mixing tank can be obtained through a pre-constructed corresponding relationship curve between fuel consumption and the real-time speed of the mixing tank, such as Figure 3 shown. Figure 3 The different curves are relationship curves under different loads (the figure shows 25% load, 50% load and 100% load). For the same model of concrete mixer truck, the load weight usually corresponds to a fixed curve. The setting of multiple curves can make the constructed model applicable to more models. Figure 3 , Figure 4 The horizontal axis is the speed and the vertical axis is the fuel consumption.

[0145] The above-mentioned corresponding relationship between the real-time speed of the engine and the fuel consumption can be obtained through a pre-constructed corresponding relationship curve between the fuel consumption and the real-time speed of the engine, such as Figure 4 shown. Figure 4The different curves are relationship curves under different loads (the figure shows 25% load, 50% load and 100% load). For the same model of concrete mixer truck, the load weight usually corresponds to a fixed curve. The setting of multiple curves can make the constructed model applicable to more models.

[0146] Therefore, in this embodiment, after determining the current real-time speed of the engine and the real-time speed of the mixing tank, the influence of the current real-time speed of the engine and the real-time speed of the mixing tank on the fuel consumption change can be determined, thereby determining the first fuel consumption change influencing parameter and the second fuel consumption change influencing parameter. Finally, the first fuel consumption change influencing parameter and the second fuel consumption change influencing parameter can be used to determine the change in the weight coefficients corresponding to the real-time speed of the engine and the real-time speed of the mixing tank, so as to update the first weight coefficient and the second weight coefficient, and use the updated first weight coefficient and the second weight coefficient to recalculate the fuel consumption index for use in subsequent fuel consumption evaluation.
