In addition, the aerial work platform control method provided by the application is not only suitable for the application scene shown in fig. 1, but also suitable for any device with aerial work platform control requirements.
In order to facilitate understanding of the aerial work platform control method provided by the embodiment of the present application, the aerial work platform control method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings:
as shown in fig. 2, an overall flowchart of a method for controlling an aerial work platform according to an embodiment of the present application is provided, where:
in step 201: determining a difference between the actual height and the limit height;
in step 202: if the difference value is smaller than the first preset value, a reminding alarm is sent to remind a user to reduce the lifting speed;
in step 203: if the operation of reducing the lifting speed by the user is detected, reducing the lifting speed according to the operation;
in step 204: if the operation of lowering the lifting speed by the user is not detected, the lifting speed is lowered, and the lifting speed is lowered to zero before the actual height is equal to the limit height.
For the convenience of understanding, the above steps are described in detail below, and in the embodiment of the present application, in order to accurately determine the height of the current aerial work platform with potential safety hazard according to the current road surface state and the current extending length of the telescopic arm, the steps shown in fig. 3 may be implemented before determining the difference between the actual height and the limit height:
in step 301: receiving a first angle, a second angle and the extending length of the telescopic arm;
as shown in fig. 4, a first angle 2 represents an angle between the aerial work platform and the telescopic boom, and a second angle 1 represents an angle between the telescopic boom and the ground; when the ground is uneven, the current appropriate height can be determined by adjusting the second angle 2 to avoid the potential safety hazard.
In some embodiments, as shown in fig. 5, an angle sensor and a position sensor are installed at the position 1 and an angle feedback sensor and a position feedback sensor are installed at the position 2 in the aerial work platform; in the embodiment of the present application, the first angle and the second angle may be determined by the above-mentioned sensors, and the current extending length of the telescopic arm may be determined by the position sensor and the position feedback sensor.
In step 302: determining a limit height according to the first angle;
in the embodiment of the present application, in order to accurately determine the limit height, formula 1 is empirically derived by those skilled in the art:
h ═ k × a, (formula 1)
Wherein: h is the limit height, k is the second preset value, and a is the first angle. The second preset value is an empirical value experimentally measured by a person skilled in the art. Through the formula 1, the accuracy of the limit height calculation is improved, and the potential safety hazard is further reduced.
In step 303: the actual height is determined based on the second angle and the length of the protrusion.
In the embodiment of the present application, in order to accurately determine the actual height, formula 2 is empirically derived by those skilled in the art:
h ═ i × L × b, (equation 2)
Wherein: h is the actual height, i is a third preset value, L is the length of the telescopic arm, and b is a second angle. i is an empirical value determined experimentally by a person skilled in the art. Through the formula 2, the accuracy of the limit height calculation is improved, and the potential safety hazard is further reduced.
In this application embodiment, when the difference between the actual height and the limit height is less than the first preset value, a warning alert is sent out, and in this application, the warning alert may include but is not limited to: instrument fault flashing, buzzer alarming, and screen displaying reminding popup windows; after the user receives the warning, the lifting speed should be reduced, but when the user reduces the lifting speed, the user may have a slow speed reduction process, so that when the actual height is equal to the limit height, the lifting speed is not reduced to 0, and then the aerial work platform can be continuously raised, so that the actual height is greater than the limit height, and further potential safety hazards are generated. Therefore, in the embodiment of the present application, when the actual height is equal to the limit height, the lifting speed is not zero, and the lifting speed is reduced to zero by the control of the aerial cage or the server.
The first preset value may be set as follows in the embodiment of the present application: the first preset value is 5% H, that is, the first preset value is in a positive correlation with the limit height, and when the limit height is higher, the first preset value is larger, for example: when the limit height is 100 meters, the first preset value is 5 meters, and when the actual height is equal to 95 meters, a reminding alarm is sent out to remind a user to reduce the lifting speed; when the limit height is 200 meters, the first preset value is 10 meters, and when the actual height is 190 meters, a reminding alarm is sent out to remind a user of reducing the speed. Since the higher the height, the more potential safety hazards are likely to occur, and therefore the earlier the lifting speed needs to be reduced, the lifting speed is set to have a positive correlation with the limit height in the present application. The first preset value is flexibly set, so that potential safety hazards are further avoided.
In the embodiment of the present application, the operation of lowering the lifting speed by the user is not detected, and when lowering the lifting speed, the following method may be adopted to lower the speed:
1. lowering the lifting speed according to a specified acceleration
Firstly, determining the distance between the current position and the limit height, and then determining the current lifting speed; and determining the acceleration according to the current lifting speed and the distance between the current position and the limit height, and then reducing the lifting speed according to the acceleration.
2. Lowering the lifting speed according to the distance
Firstly, determining the distance between the current position and the limit height, and then reducing the lifting speed by adopting different accelerations according to the distance between the current position and the limit height from the current position, for example: and when the distance between the lifting speed and the limit height is 5 meters, the lifting speed is reduced by adopting an acceleration of-1 meter/second, and when the distance between the lifting speed and the limit height is 4 meters, the lifting speed is reduced by adopting an acceleration of-2 meters/second.
In the method provided by the embodiment of the application, the aerial work platform truck adopts the respective control advantages of hydraulic pressure and an engine when reducing the lifting speed, and the safety of the aerial work platform truck can be ensured even if an operator does not realize that the working height reaches the safety limit value. By the method, when the difference value is smaller than the first preset value, the lifting speed of the aerial work platform is limited by the aerial work vehicle through automatically controlling the displacement of the lifting pump and the running speed of the engine, when the limit height is reached, the lifting speed is reduced to 0, and meanwhile, the engine is in idle speed, so that the operation safety is improved.
For convenience of understanding, the following describes an overall flow of the aerial work platform control method provided in the embodiment of the present application, as shown in fig. 6:
in step 601: receiving a first angle, a second angle and the extending length of the telescopic arm;
in step 602: determining a limit height according to the first angle, and determining an actual height according to the second angle and the protruding length;
in step 603: determining a difference between the actual height and the limit height;
in step 604: judging whether the first difference value is smaller than a first preset value, if so, entering a step 605, otherwise, entering a step 602;
in step 605: judging whether the user reduces the lifting speed, if so, entering a step 606, otherwise, entering a step 607;
in step 606: when the actual height is equal to the limit height, whether the lifting speed is equal to 0 is determined, if so, the step 602 is executed, otherwise, the step 608 is executed;
in step 607: reducing the lifting speed to zero before the actual height is equal to the limit height;
in step 608: the lift speed is reduced to zero.
