Aerial work platform navigation method, device and equipment and aerial work platform

Abstract

The invention relates to the field of work platform control, and provides an aerial work platform navigation method, device and equipment and an aerial work platform. The aerial work platform navigation method comprises the following steps: acquiring a target point selected by a user in a work scene image; extracting a continuous characteristic value of the target point from the working scene image; constructing the continuous characteristic values into a target function of the target point; responsive to a navigation starting instruction, acquiring an image including the target point at the visual angle of the work platform; recognizing the target function from the acquired image to obtain a relative position of the target point and the work platform; and generating an action execution instruction according to the relative position, wherein the action execution instruction is used for controlling each supporting component of the work platform to enable the work platform to approach or reach the target point. According to the implementation mode provided by the invention, the intelligence of operation platform control is improved.

Description

technical field [0001] The invention relates to the field of work platform control, in particular to a navigation method for a high-altitude work platform, a navigation device for a high-altitude work platform, a navigation device for a high-altitude work platform, and a high-altitude work platform. Background technique [0002] Aerial work equipment is a kind of special equipment that lifts staff and machinery to a designated position in the sky for installation, maintenance, rescue and other operations, such as climbing fire trucks, straight arm aerial work platforms, and articulating arm aerial work platforms , scissor-type aerial work platform, aerial work vehicle (vehicle-mounted aerial work platform), etc. In the process of installation, maintenance, rescue and other operations of aerial work equipment, the operator needs to be sent to the designated position through the working platform. At present, it mainly depends on the operator to achieve. The specific operator f...

AI Technical Summary

Problems solved by technology

In the process of installation, maintenance, rescue and other operations of aerial work equipment, the operator needs to be sent to the designated position through the working platform. At present, it mainly depends on the operator. Each movable joint gradually approaches the target point, and finally reaches the designated position. This method mainly relies on the experience of the operator. For unskilled operators, the positioning time is long and may be inaccurate, and for complex positioning, it is necessary to operate multiple joints. Inconvenient, seriously affecting work efficiency

[0003] Chinese patent CN201310581218.6 discloses a positioning and navigation device, a fire truck and a method for a fire truck working platform on a climbing platform, but the patent does not disclose how to obtain target point information, but directly inputs target point information. Target point information acquisition in technology usually includes ultrasonic positioning technology, infrared positioning technology, ultra-wideband positioning technology, radio frequency positioning technology, laser positioning technology and visible light positioning technology, etc. These technologies have a common feature that they need to use electronic tags or similar devices for positioning Target point, this type of technology is usually applied to occasions where the place is relatively fixed (such as indoors) or the target is relatively fixed (the electronic tag is attached to the positioning object), and the cost is relatively high. The aerial work vehicle needs to work in an open outdoor environment, and the target point Frequent changes and difficult installation of electronic tags are not suitable for the above-mentioned spatial positioning technology

The position information of the target is only solved once, and the beam generator will also shift during the movement, resulting in low positioning accuracy; in the process of target positioning, the operator is required to assist, and if there is an abnormal situation Manual participation is required to cut off the control, and there is no safety protection
