Intelligent control method and system of cantilever type rescue fire truck in narrow and small region

Abstract

The invention discloses an intelligent control method and system of a cantilever type rescue fire truck in a narrow and small region. According to the intelligent control method, through demarcating of the position needing rescue and sensing of the space around the rescue fire truck, the stretching path of a cantilever is made, and the spreading range of support legs is rapidly determined; if theexisting space around a chassis cannot meet rescue requirements, an appropriate parking position is marked out, and an operator is assisted in conducting corresponding correction according to the marked parking position. The intelligent control method greatly saves the rescue time of the cantilever type rescue vehicle, avoids the situation that due to limitation of chassis space, the spreading ranges of the left and right support legs or the position of the chassis are frequently changed, greatly shortens the rescue preparing time and improves efficiency and avoids personal and property loss.The intelligent control method and system are suitable for cantilever type rescue fire trucks in the narrow and small regions.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to an intelligent control method and system for a boom-type rescue fire truck in a narrow area. Background technique [0002] Boom-type construction machinery needs to open the outriggers when the boom is deployed. The opening range of the outriggers will limit the range of motion of the boom to prevent the center of gravity of the vehicle from shifting and causing the vehicle to tip over. Different combinations of outrigger reach will have a direct impact on boom reach. For areas with dense population, narrow roads, and lack of basic fire protection facilities, such as shantytowns and urban-rural junctions, the particularity of the operating area has a strong limit on the extension range of its outriggers. [0003] The existing control technology generally limits the movement range, angle or trajectory of the boom by detecting the extension range of the ...

AI Technical Summary

Problems solved by technology

[0004] Disadvantages of the existing technology: none of the existing control methods and systems can pre-plan the parking area of ​​the chassis of the boom-type construction machinery. When the space around the chassis is narrow, it will directly limit the extension range of the outriggers, which in turn will limit the boom. If the space planning is not carried out in advance, it will be impossible or unable to deploy the boom as soon as possible to carry out rescue, resulting in greater personal or property losses
