Example 1
Fig. 1 is a flowchart of a lifting control method of an excavator, which is provided according to a first embodiment of the present invention, and the present embodiment may be suitable for controlling a smooth lifting of the excavator, where the method may be performed by a lifting control device of the excavator, and the lifting control device of the excavator may be implemented in a hardware and/or software form, and the lifting control device of the excavator may be configured in an electronic device such as a computer, a server, or a tablet computer. Specifically, referring to fig. 1, the method specifically includes the following steps:
step 110, responding to a change instruction of an electronic accelerator pedal signal of a target excavator, and acquiring the current rotating speed and the current pump current parameter of an engine of the target excavator.
The target excavator can be any mechanical transmission wheel type excavator, can carry out lifting operation, and can be widely applied to working conditions such as municipal construction, forestry wood grabbing, agricultural lifting and the like.
In an optional implementation manner of this embodiment, when the controller in the excavator receives a change instruction of the electronic accelerator pedal signal, that is, when it is detected that the lifting mode of the excavator is turned on, the lifting mode control system is activated, the current rotation speed and the current pump current parameter of the engine of the target excavator may be further obtained.
Optionally, in this embodiment, the response to the change instruction of the electronic accelerator pedal signal of the target excavator may include: determining whether the target excavator starts a lifting mode; and under the condition that the lifting mode is determined to be started, determining whether the electronic accelerator pedal signal changes or not.
It CAN be appreciated that in this embodiment, the on state of the swing pattern may be transferred to the controller via a CAN bus or a local area network; the set rotating speed and the pump current parameters under the lifting mode of the vehicle can be set on the instrument interface, and the rotating speed information is fed back through a rotating speed sensor arranged at the flywheel of the engine. The control panel can set an initial throttle gear, and control the power output of the electric control pump corresponding to the engine speed and the pump current parameters of each gear. In the lifting operation, the initial value of the rotation speed of the mechanical driving wheel when the vehicle starts to walk is the value of the initial accelerator gear, which is called the current rotation speed in the embodiment because of the operation characteristic of manual gear shifting.
In an alternative implementation of this embodiment, whether the target excavator is in the lifting mode may be determined by the controller of the target excavator, for example, whether the target excavator is in the lifting mode may be determined by the result displayed on the display; the method can also determine whether the target excavator starts the lifting mode or not according to the lifting mode signal by detecting the lifting mode signal (0 or 1); further, under the condition that the opening lifting mode of the target excavator is determined, whether the electronic accelerator pedal signal changes can be further determined.
It should be noted that, if the target excavator is detected not to be started in the hoisting mode, the current rotation speed of the engine of the target excavator and the current pump current parameter do not need to be acquired even if the electronic accelerator pedal signal is determined to be changed.
And 120, when the current rotating speed and the set rotating speed of the engine meet the preset relation, adjusting the current rotating speed to the set rotating speed, and adjusting the current pump current parameter to the set pump current parameter.
In this embodiment, the preset relationship may be that the absolute value of the difference between the current rotation speed and the set rotation speed is less than or equal to a set rotation speed threshold, where the set rotation speed threshold is 100r/min, or may be 120r/min or 90r/min, or the like, which is not limited in this embodiment. The set rotation speed may be 1000r/min, or 2000r/min, which is related to user setting, and the specific numerical value is not limited in this embodiment; the pump current parameter may be set to any value, and is not limited in this embodiment.
In an optional implementation manner of this embodiment, after obtaining the current rotation speed and the current pump current parameter of the engine of the target excavator, it may be further determined whether the obtained current rotation speed and the set rotation speed of the engine satisfy a preset relationship; for example, it may be determined whether the obtained difference between the current rotation speed and the set rotation speed limit is less than or equal to 100r/min; if yes, determining that the current rotating speed and the set rotating speed of the engine meet a preset relation; further, the current rotational speed of the engine may be adjusted to a set rotational speed, and the current pump current parameter may be adjusted to a set pump current parameter.
In a specific example of the present embodiment, if the obtained current rotation speed of the engine is 2100r/min, the rotation speed is set to 2000r/min; the current pump current parameter is 3A, and the pump current parameter is set to be 2.5A; the difference value of the current rotating speed minus the set rotating speed is 100r/min (equal to the set rotating speed threshold value), then the current rotating speed and the set rotating speed of the engine can be determined to meet the preset relation; the current rotational speed may be adjusted to 2000r/min; the current pump current parameter is adjusted to 2.5A.
And 130, when the current rotating speed and the set rotating speed of the engine are determined not to meet the preset relation, and the current rotating speed is smaller than the set rotating speed, increasing the current rotating speed to the set rotating speed at a set speed, and increasing the current pump current parameter to be a set pump current parameter at the set speed.
In an optional implementation manner of this embodiment, after obtaining the current rotation speed and the current pump current parameter of the engine of the target excavator, it may be further determined whether the obtained current rotation speed and the set rotation speed of the engine satisfy a preset relationship; for example, it may be determined whether the obtained current rotation speed and the set rotation speed limit difference is greater than 100r/min; if yes, determining that the current rotating speed and the set rotating speed of the engine do not meet a preset relation; further, if it is simultaneously determined that the current rotational speed is less than the set rotational speed, the current rotational speed may be increased to the set rotational speed at a set rate, and the current pump current parameter may be increased to the set pump current parameter at the set rate.
The set rate may be a smaller rate, for example, 10 r/min, 20r/min, or 0.1A/min, which is not limited in this embodiment.
In a specific example of the present embodiment, if the obtained current rotation speed of the engine is 1820r/min, the rotation speed is set to 2000r/min; the current pump current parameter is 2A, and the pump current parameter is set to be 2.5A; the absolute value of the current rotating speed minus the set rotating speed is 180r/min, then the current rotating speed and the set rotating speed of the engine can be determined to not meet the preset relation, and the current rotating speed 1820r/min is smaller than the set rotating speed 2000r/min; the current rotational speed may be increased to 2000r/min at a rate of 20r per minute; the current pump current parameter increases to 2.5A at a rate of 0.2A per minute.
In another alternative implementation manner of the present embodiment, in a case where it is determined that the current rotation speed and the set rotation speed of the engine do not satisfy a preset relationship, if it is determined that the current rotation speed is greater than the set rotation speed, the current rotation speed and the current pump current parameter may be kept unchanged.
According to the technical scheme, the current rotating speed and the current pump current parameters of an engine of a target excavator are obtained by responding to a change instruction of an electronic accelerator pedal signal of the target excavator; when the current rotating speed and the set rotating speed of the engine meet the preset relation, adjusting the current rotating speed to the set rotating speed, and adjusting the current pump current parameter to a set pump current parameter; when the current rotating speed and the set rotating speed of the engine are determined not to meet the preset relation, and the current rotating speed is smaller than the set rotating speed, the current rotating speed is increased to the set rotating speed at a set speed, and the current pump current parameter is increased to the set pump current parameter at the set speed, so that stable lifting of the excavator in lifting operation and safety in lifting process can be guaranteed.
Example two
Fig. 2 is a flowchart of a lifting control method of an excavator according to a second embodiment of the present invention, where the present embodiment is further elaborated on the above technical solutions, and the technical solutions in the present embodiment may be combined with each of the alternatives in one or more embodiments. As shown in fig. 2, the swing control method of the excavator may include the steps of:
step 210, responding to a change instruction of an electronic accelerator pedal signal of a target excavator, and acquiring the current rotating speed and the current pump current parameter of an engine of the target excavator.
Step 220, when it is determined that the current rotation speed and the set rotation speed of the engine meet a preset relationship, adjusting the current rotation speed to the set rotation speed, and adjusting the current pump current parameter to a set pump current parameter.
Step 230, when it is determined that the current rotation speed and the set rotation speed of the engine do not satisfy the preset relationship and the current rotation speed is smaller than the set rotation speed, increasing the current rotation speed to the set rotation speed at a set rate, and increasing the current pump current parameter to the set pump current parameter at the set rate.
Step 240, determining whether the target excavator exits the swing mode or not in response to a brake command of the target excavator; if it is determined that the target excavator does not exit the swing mode, the current rotation speed and the current pump current parameters are kept unchanged.
In an optional implementation manner of this embodiment, when the controller of the target excavator receives the braking instruction, it may further determine whether the target excavator exits the lifting mode; if the target excavator is determined not to exit the lifting mode, the current rotating speed and the current pump current parameter are kept unchanged, the target excavator is ensured to run at the original rotating speed and the original pump current parameter, and the phenomenon of shaking of the target excavator in the running process is avoided.
In another optional implementation manner of this embodiment, if it is determined that the target excavator exits the lifting mode, the current rotation speed is adjusted to an initial rotation speed, and the current pump current parameter is adjusted to a set pump current parameter, so that the target excavator can be guaranteed to return to the initial running state quickly, and the excavator can be prevented from running too fast or too slow under the condition of exiting the lifting mode as much as possible, so that the working efficiency of the excavator is affected.
In a specific example of this embodiment, when the controller detects that the lifting mode of the excavator is on, the lifting mode control system is activated, and if the controller detects a change in the signal of the electronic accelerator pedal, that is, the driver acts on the accelerator pedal, the controller detects the rotation speed (current rotation speed) of the initial gear and the pump current parameter, and the current rotation speed is compared with the set rotation speed; if the absolute value of the difference between the current rotating speed and the set rotating speed is smaller than or equal to 100r/min, the rotating speed of the engine is immediately changed to the set rotating speed, and the pump current parameter is changed to a set value; if the absolute value of the difference between the current rotating speed and the set rotating speed is greater than 100r/min, if the current rotating speed is lower than the set rotating speed, the rotating speed of the engine is changed to the set rotating speed at a steady and slow speed, the speed can be adjusted by a program, and the pump current parameter is changed to a set value along with the rotating speed; if the current rotation speed is higher than the set rotation speed, the rotation speed of the engine is kept at the current rotation speed, and the pump current is kept at the initial gear value.
Further, when a driver steps on the brake, the controller detects a brake signal, and at the moment, the controller judges whether to exit the hoisting mode, and if the hoisting mode is still in the hoisting mode, the engine speed and the pump current parameters keep the current values; if the hoisting mode is exited, the engine speed and the pump current parameters are slowly changed to the set values.
