All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 schematically shows a flow diagram of a control method for a boom according to an embodiment of the application. As shown in fig. 1, in an embodiment of the present application, there is provided a control method for an arm support, including the following steps:
And 101, detecting the ambient wind speed of the arm support in real time.
And 102, comparing the ambient wind speed with a preset wind speed to determine an allowable maximum length threshold corresponding to the ambient wind speed.
Step 103, obtaining the arm support length of the arm support.
And 104, reducing the length of the arm support under the condition that the length of the arm support is larger than the allowable maximum length threshold value, so that the ambient wind speed is smaller than or equal to the allowable maximum wind speed corresponding to the adjusted length of the arm support.
The arm support is controlled, and the processor can detect the ambient wind speed of the arm support in real time. The arm support can refer to an arm support of a manned elevating fire truck or other high-altitude operation machinery. After the ambient wind speed of the arm support is obtained, the processor can compare the ambient wind speed with a preset wind speed to determine an allowable maximum length threshold corresponding to the ambient wind speed. The preset wind speed may include a plurality of wind speeds. The processor may compare the ambient wind speed to a plurality of preset wind speeds to determine an allowable maximum length threshold corresponding to the ambient wind speed. The ambient wind speed may be divided into a plurality of gear steps, and each ambient wind speed gear step may correspond to an allowable maximum length threshold. The gear of the environmental wind speed division can be customized according to actual conditions, and accordingly, the allowable maximum length threshold can be respectively set according to the grade of the environmental wind speed division. For example, if the ambient wind speed is divided into four gears, then a corresponding maximum allowable length threshold may be set for each of the four ambient wind speed gears. Under the condition that the allowable maximum length threshold is determined, the processor can acquire the boom length of the boom. The processor may then determine whether the boom length is greater than the maximum allowed length threshold. If the length of the arm support is greater than the allowable maximum length threshold, the processor may reduce the length of the arm support so that the ambient wind speed is less than or equal to the allowable maximum wind speed corresponding to the adjusted length of the arm support.
According to the technical scheme, the length of the arm support is controlled in a grading manner based on the ambient wind speed, so that the performance advantage of the arm support is exerted to a greater extent, the arm support can be suitable for working conditions under different wind speeds, the arm support is controlled more flexibly, and the application scene is wider.
In one embodiment, the preset wind speed includes a first wind speed, and comparing the ambient wind speed with the preset wind speed to determine the allowable maximum length threshold corresponding to the ambient wind speed includes: and under the condition that the ambient wind speed is smaller than or equal to the first wind speed, determining the allowable maximum length threshold corresponding to the ambient wind speed as the first length threshold.
In this embodiment, the preset wind speed may include a first wind speed. The ambient wind speed may be represented by V and the first wind speed may be represented by V1. The first length threshold may be represented by L1. In the case that the ambient wind speed is less than or equal to the first wind speed, the processor may determine that the maximum allowable length threshold corresponding to the ambient wind speed is the first length threshold. That is, in the case where V.ltoreq.V1, the processor may determine the allowable maximum length threshold corresponding to the ambient wind speed as L1.
In one embodiment, the preset wind speed includes a second wind speed, and comparing the ambient wind speed with the preset wind speed to determine the allowable maximum length threshold corresponding to the ambient wind speed includes: under the condition that the ambient wind speed is less than or equal to the second wind speed, determining that the maximum allowable length threshold corresponding to the ambient wind speed is the second length threshold; wherein the first wind speed is greater than the second wind speed and the first length threshold is less than the second length threshold.
In this embodiment, the preset wind speed may include a second wind speed. The ambient wind speed may be represented by V and the second wind speed may be represented by V2. The second length threshold may be represented by L2 and the first length threshold may be less than the second length threshold. In the case that the ambient wind speed is less than or equal to the second wind speed, the processor may determine that the allowable maximum length threshold corresponding to the ambient wind speed is the second length threshold. That is, in the case where V.ltoreq.V2, the processor may determine the allowable maximum length threshold corresponding to the ambient wind speed as L2.
In one embodiment, the preset wind speed includes a third wind speed, and comparing the ambient wind speed with the preset wind speed to determine the allowable maximum length threshold corresponding to the ambient wind speed includes: under the condition that the ambient wind speed is smaller than or equal to the third wind speed, determining that the maximum allowable length threshold corresponding to the ambient wind speed is the third length threshold; wherein the second wind speed is greater than the third wind speed and the second length threshold is less than the third length threshold.
In this embodiment, the preset wind speed may include a third wind speed. The ambient wind speed may be denoted by V and the third wind speed may be denoted by V3. The third length threshold may be represented by L3 and the second length threshold may be less than the third length threshold. In the case that the ambient wind speed is less than or equal to the third wind speed, the processor may determine that the allowable maximum length threshold corresponding to the ambient wind speed is the third length threshold. That is, in the case where V.ltoreq.V3, the processor may determine the allowable maximum length threshold corresponding to the ambient wind speed as L3.
It should be noted that the preset wind speed may include a first wind speed, a second wind speed, and a third wind speed. Wherein, there may be a certain relationship among the first wind speed, the second wind speed, and the third wind speed. That is, V1 > V2 > V3. In addition, the allowable maximum length threshold may include a first length threshold, a second length threshold, and a third length threshold. Wherein, there may be a certain relationship among the first length threshold, the second length threshold, and the third length threshold. That is, L1 < L2 < L3 can be expressed.
In one embodiment, further comprising: acquiring the boom tipping direction of the boom and the ambient wind direction of the boom in real time; under the condition that the tipping direction of the arm support is consistent with the wind direction of the ambient wind direction, the direction of the arm support is adjusted so that the tipping direction of the arm support is opposite to the wind direction of the ambient wind direction.
The processor can acquire the boom tipping direction of the boom and the ambient wind direction of the boom in real time. The environmental wind direction of the arm support can be determined through a wind direction sensor. The tilting direction of the arm support can be determined according to the amplitude variation angle detected by the inclination angle sensor and the rotation angle detected by the rotation encoder. Under the condition that the boom tipping direction of the boom and the environmental wind direction of the boom are obtained, if the boom tipping direction is consistent with the wind direction of the environmental wind direction, the processor can adjust the direction of the boom so that the boom tipping direction is opposite to the wind direction of the environmental wind direction, and therefore the safety and stability of boom operation are guaranteed.
In one embodiment, further comprising: and under the condition that the tipping direction of the arm support is opposite to the wind direction of the ambient wind direction, the arm support is allowed to normally act.
Under the condition that the tipping direction of the arm support is opposite to the wind direction of the ambient wind direction, the processor can allow the arm support to normally act. Allowing normal motion of the boom may refer to allowing the boom to perform actions such as luffing, telescoping, and slewing.
In one embodiment, further comprising: and under the condition that the length of the arm support is greater than the allowable maximum length threshold, sending an alarm instruction to an alarm device so as to start an alarm prompt through the alarm device.
In this embodiment, the alarm device may refer to an audible and visual alarm device. When the alarm prompt is started by the alarm device, the alarm prompt can comprise a voice broadcast prompt, an alarm lamp flashing prompt, a text display prompt and the like. Specifically, the voice broadcasting prompt and/or the text prompt can be a prompt such as 'over wind speed, only arm support retraction allowed', and the like. And under the condition that the length of the arm support is greater than the allowable maximum length threshold, the processor can send an alarm instruction to the alarm device so as to start an alarm prompt through the alarm device. For example, after detecting the ambient wind speed of the boom, the processor compares the ambient wind speed with a preset wind speed to determine that the maximum allowable length threshold corresponding to the ambient wind speed is the first length threshold. Then, after the processor obtains the arm support length of the arm support, if the arm support length is determined to be greater than the first length threshold, that is, if the arm support length is not less than or equal to the first length threshold, the processor may send an alarm instruction to the alarm device, so as to start an alarm prompt through the alarm device.
In one embodiment, further comprising: and allowing the arm support to normally act under the condition that the length of the arm support is smaller than or equal to the allowable maximum length threshold.
And under the condition that the length of the arm support is smaller than or equal to the allowable maximum length threshold, the processor can allow the arm support to normally act. For example, after detecting the ambient wind speed of the boom, the processor may compare the ambient wind speed with a preset wind speed to determine that the maximum allowable length threshold corresponding to the ambient wind speed is the first length threshold. Then, after the processor obtains the length of the arm support, if the length of the arm support is less than or equal to the first length threshold, the processor can allow the arm support to normally act.
In one embodiment, as shown in fig. 2, a flow diagram of a control method for the boom is also provided. The processor can detect the arm support length L and the ambient wind speed V in real time. The processor may then determine the relationship between the ambient wind speed V and the wind speed setpoints V1, V2, and V3. Wherein V1 may refer to a first wind speed, V2 may refer to a second wind speed, and V3 may refer to a third wind speed. The relationship between the ambient wind speed V and the wind speed set values V1, V2 and V3 can be V.ltoreq.V1, V.ltoreq.V2 and V.ltoreq.V3.
If V is less than or equal to V1, whether the length L of the arm support is less than or equal to L1 can be continuously judged, and L1 can be expressed as a first length threshold corresponding to the ambient wind speed. Wherein the first length threshold may be determined if the ambient wind speed is less than or equal to the first wind speed. At this time, if the boom length L is determined to be less than or equal to the first length threshold L1, the processor may allow the boom to normally operate. If the boom length L is not less than or equal to the first length threshold L1, that is, if the boom length L is greater than the first length threshold L1, the processor may send out an audible and visual alarm and/or a screen prompt. The content of the screen prompt can be 'over wind speed, only allowing the arm support to retract'.
If V is less than or equal to V2, whether the length L of the arm support is less than or equal to L2 can be continuously judged, and L2 can be expressed as a second length threshold corresponding to the ambient wind speed. Wherein the second length threshold may be determined if the ambient wind speed is less than or equal to the second wind speed. At this time, if the boom length L is determined to be less than or equal to the second length threshold L2, the processor may allow the boom to normally operate. If the boom length L is not less than or equal to the second length threshold L2, that is, if the boom length L is greater than the second length threshold L2, the processor may send an audible and visual alarm and/or a screen prompt. The content of the screen prompt can be 'over wind speed, only allowing the arm support to retract'.
If V is less than or equal to V3, whether the length L of the arm support is less than or equal to L3 can be continuously judged, and L3 can be expressed as a third length threshold corresponding to the ambient wind speed. Wherein the third length threshold may be determined if the ambient wind speed is less than or equal to the third wind speed. At this time, if the boom length L is determined to be less than or equal to the third length threshold L3, the processor may allow the boom to normally operate. If the boom length L is not less than or equal to the third length threshold L3, that is, if the boom length L is greater than the third length threshold L3, the processor may send an audible and visual alarm and/or a screen prompt. The content of the screen prompt can be 'over wind speed, only allowing the arm support to retract'.
According to the technical scheme, the length of the arm support is controlled in a grading mode based on the ambient wind speed, and the arm support is not limited to execute normal actions such as amplitude variation, expansion and rotation under the condition that the ambient wind speed is at a certain preset threshold value. But the normal action of the arm support is limited under the condition that the length of the arm support exceeds the allowable maximum length threshold, so that the performance advantage of the arm support is exerted to a greater extent, the arm support can be suitable for working conditions under different wind speeds, the control of the arm support is more flexible, and the application scene is wider.
