Based on this, embodiments of the present application provide a power matching adaptive control method, apparatus, device, and storage medium, which are described below by way of embodiments.
An embodiment of the present application provides a power matching adaptive control method, and fig. 1 is a schematic flow diagram of the power matching adaptive control method provided in the embodiment of the present application, as shown in fig. 1, the power matching adaptive control method includes the following steps:
step S101: and acquiring target parameters acquired by a sensor, wherein the target parameters comprise water temperature, hydraulic oil temperature and actual rotating speed of the engine when the engine works under a calibrated power.
Specifically, the engine controller acquires water temperature parameters in real time through a water temperature sensor, acquires actual rotating speed parameters of the engine in real time through a rotating speed sensor, and transmits the water temperature parameters and the actual rotating speed parameters of the engine to the vehicle body controller in real time; the automobile body controller receives the water temperature parameter and the actual rotating speed parameter sent by the engine controller in real time, and acquires the hydraulic oil temperature parameter in real time through the hydraulic oil temperature sensor.
For example, the engine Controller collects water temperature parameters in real time through a water temperature sensor and sends the water temperature parameters to the vehicle body Controller in real time through CAN (Controller Area Network) communication; the engine controller acquires actual rotating speed parameters of the engine in real time through a rotating speed sensor and sends the actual rotating speed parameters to the vehicle body controller in real time through CAN communication; the vehicle body controller receives the hydraulic oil temperature parameters acquired by the hydraulic oil temperature sensor in real time through CAN communication.
Step S102: when a first fault signal which is sent by an engine controller and used for indicating engine faults is not received, the water temperature is within a first preset range, and the hydraulic oil temperature is within a second preset range, the change situation of a target difference value of the engine within a first preset time length is determined according to the target rotating speed and the actual rotating speed of the engine, wherein the target difference value is the difference value of the target rotating speed and the actual rotating speed.
Specifically, if the engine fails, the engine controller sends a first fault signal for indicating the engine failure to the vehicle body controller and the display screen, and the vehicle body controller stops the signal acquisition operation and the difference value change condition determination operation after receiving the first fault signal; the display screen displays the first fault signal so that a worker can maintain the engine in time; the water temperature is in a first preset range, which indicates that the water temperature is normal, and the hydraulic oil temperature is in a second preset range, which indicates that the hydraulic oil temperature is normal; if the engine has a fault, the water temperature is abnormal or the hydraulic oil temperature is abnormal, acquiring parameters and determining the difference value, and generating an error for identifying the abnormality or controlling the abnormality; the target rotating speed and the actual rotating speed are the target rotating speed and the actual rotating speed of the engine in a certain gear; the difference between the target rotational speed and the actual rotational speed is generally greater than zero, that is: the engine is decelerated; the change condition of the target difference value of the engine in the first preset time period is as follows: acquiring real-time actual engine rotating speed parameters, calculating a difference value between a target rotating speed and the real-time actual rotating speed to obtain a real-time difference value, acquiring all the difference values in a first preset time period, and obtaining the change condition of the difference values in the first preset time period, namely: a stall condition of an engine, the stall condition comprising: a stall value, a stall duration, and a stall frequency of the engine.
For example, the vehicle body controller sends the target rotating speed to the engine controller in real time through the CAN communication, so that the engine controller controls the actual rotating speed of the engine, and when the vehicle body controller does not receive the fault code sent by the engine controller through the CAN communication, the water temperature is 70-90 degrees centigrade, and the hydraulic oil temperature is 50-80 degrees centigrade, the real-time difference value between the real-time target rotating speed and the real-time actual rotating speed of the engine within 2 minutes is calculated, that is: and (4) real-time speed dropping amount.
Step S103: and judging whether the change condition meets a preset condition, wherein the preset condition is that the frequency of occurrence of a target condition included in the change condition is greater than a preset frequency, and the target condition is that the duration of a continuous target difference value which is greater than a preset value in the change condition exceeds a second preset duration.
Specifically, if the variation condition meets the preset condition, it indicates that the current engine performance does not meet the operating condition requirement of the engine.
For example, if the difference between the target rotation speed and the actual rotation speed of the engine is within 2 minutes, the difference is greater than 200 revolutions and lasts for more than 2 seconds for more than 3 times, the change situation of the difference meets the preset condition, and the current engine performance does not meet the operating condition requirement of the engine.
Step S104: and if the change condition meets the preset condition, reducing the power of the engine from the calibrated power to a target power, wherein the change condition of the difference value between the target rotating speed and the current rotating speed of the engine when the engine works under the target power does not meet the preset condition.
Specifically, if the change condition does not meet the preset condition, the operation of reducing power is not performed, and the engine operates under the original calibration power; an engine operating at a target power has a performance that meets the operating condition requirements of the engine.
In one possible embodiment, the step of reducing the power of the engine from the calibration power to the target power comprises: and gradually reducing the power of the engine according to a preset proportion by taking the calibration power as a start until the power of the engine is equal to the target power.
Specifically, a fixed proportion is set, the calibration power is reduced according to the fixed proportion to obtain the reduced engine power, if the engine power is not equal to the target power, the engine power is continuously reduced according to the fixed proportion, and the operation is repeated until the reduced engine power is equal to the target power.
For example, if the power is 100 and the fixed ratio is 3%, the engine power after the first reduction is 97, if 97 is not equal to the target power, the engine power after the second reduction is 67.9, and if the power with the value of 67.9 is equal to the target power, the engine power is not reduced.
In a possible embodiment, after the power of the engine is reduced gradually according to a preset ratio, the power matching adaptive control method further includes the following operations:
after the power of the engine is reduced each time, and the water temperature is within the first preset range, and the hydraulic oil temperature is within the second preset range, whether the first fault signal sent by the engine controller is received, and whether the change situation of the current difference value meets the preset condition are judged.
If the above conditions are simultaneously satisfied, the operation of successively reducing the power of the engine according to the preset ratio is continued.
Specifically, after power is reduced each time, whether the water temperature of the engine is within a first preset range or not and whether the hydraulic oil temperature of the engine is within a second preset range or not are required to be judged, if the water temperature and the hydraulic oil temperature are within the ranges, whether a first fault signal is received or not is judged, if the fault signal is not received, the fact that the engine is not abnormal is indicated, whether the change condition of the rotating speed difference value of the engine working under the current power meets a preset condition or not is detected, if the preset condition is met, power reduction operation is continued, and if the preset condition is not met, power reduction operation is stopped; if one of the three conditions is not satisfied, the power-down operation is stopped.
In a possible embodiment, the power matching adaptive control method further includes, during the step of reducing the power of the engine by a preset ratio, the following operations:
and when the power of the engine generated after each reduction operation is smaller than a preset power, sending a second fault signal for indicating that the power of the engine generated after each reduction operation is smaller than the preset power to a display, wherein the preset power is a preset percentage of the calibration power.
Specifically, the preset power is the lowest power of the engine which is set in advance and normally runs, and if the power of the engine is smaller than the preset power, which indicates that the engineering machinery has a fault, a signal indicating the fault is sent to a display to display and alarm, so that a worker can maintain the engineering machinery in time.
For example, the preset power is set to be 30% of the engine calibration power, and when the reduced engine power is smaller than the preset power, the vehicle body controller sends a signal for displaying the engineering machinery fault to the display for displaying through the CAN communication, so as to prompt a worker to perform maintenance work in time.
In a possible embodiment, the power matching adaptive control method further includes using the target power instead of the calibration power so that the engine operates at the target power after each start.
Specifically, the nominal power value of the engine operation stored in the memory of the control system is changed to the target power value, that is: solidifying the target power so that the engine can directly work at the target power when starting to run each time; and transmitting the parameter value of the target power to a display for displaying while solidifying the target power so as to enable a worker to clearly determine the current working power of the engine.
In a possible implementation, fig. 2 is a schematic flowchart of a method for setting power through a display screen according to an embodiment of the present application, and as shown in fig. 2, the power matching adaptive control method further includes the following steps:
step S201: and acquiring power set by a user, wherein the power set by the user can be set on a display screen of the host computer or can be set by adjusting the maximum swash plate angle of the main pump.
Specifically, the power set by the user is the power of the engine at a certain gear, and the power corresponding to different gears set by the user through a display screen or set by adjusting the maximum swash plate angle of the main pump is obtained.
Step S202: and replacing the calibration power with the user set power so that the engine operates at the user set power after each start.
For example, the priority of the power set by the user is higher than the priority of the adaptive matching target power, that is: and after the power set by the user is used for replacing the calibration power, any operation from parameter acquisition to power reduction for matching is not performed.
In a possible implementation, fig. 3 is a schematic flowchart of a method for resetting power by clicking an initialization key according to an embodiment of the present application, where as shown in fig. 3, a power parameter includes the target power or the power set by the user, and after the power parameter is used to replace the calibration power, the power matching adaptive control method further includes the following steps:
step S301: and acquiring an initialization instruction generated by clicking an initialization key on the host display screen by the user.
Step S302: and restoring the power parameter to the calibration power according to the initialization command.
Specifically, different gears correspond to different powers, and the powers corresponding to the different gears can be selected for initialization.
