Positioning and navigation device, fire truck and method for working platform of fire truck on climbing platform

Abstract

The invention discloses a positioning and navigation device of a working platform of an elevating platform fire truck, the fire truck and a method. A display device and a boom detection device are electrically connected with a controller, the display device sends input target point information to the controller, the boom detection device sends acquired boom state information of the elevating platform fire truck to the controller in real time, and the controller computes navigation information of the working platform for moving to a target point in real time and sends the navigation information to the display device for displaying. According to the positioning and navigation device, the elevating platform fire truck and the method, path planning for the target point can be performed in real time according to current state of the boom, and the fire truck can arrive at the target point in an optimal manner; and moreover, an adopted navigation strategy only performs path guidance for an operator and does not intervene an actual operation process, so that dangerous working conditions that the boom touches a barrier during moving process and the like are effectively prevented, and the safe operation coefficient and the rescue efficiency of the elevating platform fire truck are improved.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to a positioning and navigation device for a working platform of an ascending platform fire truck, an ascending platform fire truck and a method. Background technique [0002] The climbing platform fire truck is equipped with a folding or folding and telescopic combined boom, a manned platform, a display turntable and a fire extinguishing device, and is used for extinguishing fires in high-rise buildings and rescue vehicles. The vehicle is equipped with a working platform and a fire water cannon (water cannon), which are special equipment for firefighters to climb up and fight fires in high-rise buildings and tall facilities, rescue trapped people, rescue valuables, and protect citizens' lives and properties. In view of its particularity and importance, the work efficiency of fire trucks on climbing platforms is particularly important in the rescue process, and th...

Problems solved by technology

However, this method has two defects. On the one hand, due to the uniqueness of its planned path, the jib may encounter obstacles such as utility poles and houses during operation, resulting in failure to reach the target point.

On the other hand, when the vehicle is close to the calculated target boom state, it will stop the current movement, but considering the stability, there will be a certain movement buffer, which will lead to the phenomenon of exceeding the theoretical boom state, and this method will not be based on the exceeding The value of the final boom state correction makes the system unable to accurately reach the target point, which affects the efficiency of emergency rescue and cannot have a high success rate in the actual rescue process.
