Engineering vehicle automatic height and speed limiting safety control system and control method thereof

Abstract

The invention discloses an engineering vehicle automatic height and speed limiting control method, which comprises the following steps of: firstly, setting height reference values H1, H2 and H3 of a movable portal frame, wherein H1< H2 <H3 , taking 105% H1-95% H2 as a safe operation height interval, and then collecting current vehicle operation state information parameters; judging whether the current vehicle operation state information parameters have the height H of the movable portal frame or not; when H is in the safe operation height interval, judging that the vehicle operates normally; otherwise, judging that the vehicle enters a limited operation state, collecting H in real time in the process, and carrying out the next cycle operation. The invention further provides an engineeringvehicle automatic height and speed limiting safety control system, and through automatic control of the vehicle controller, the ascending or descending speed of the movable portal frame is limited, and the running speed of the vehicle is limited. According to the control method, the operation height of the portal frame can be detected in real time, and the safety and comfort of the vehicle in theworking process can be effectively improved.

Description

technical field [0001] The invention belongs to the field of mechanical control, and in particular relates to an automatic height-limiting and speed-limiting safety control system for engineering vehicles and a control method thereof. Background technique [0002] Construction vehicles with fixed masts mainly include forklifts and empty container stackers, both of which belong to the handling construction machinery. The picking and stacking in the handling operation is mainly through the front fork (or attachment) of the vehicle. and gantry structure, the existing two types of engineering vehicles mentioned above are not equipped with operating height detection and corresponding safety monitoring, and basically do not have the functions of operating height limit alarm and vehicle speed limit protection. In actual work, if When the driver does not have a good safety awareness and the operation is not standardized enough, there are certain safety risks. [0003] For example: ...

Problems solved by technology

[0002] Construction vehicles with fixed masts mainly include forklifts and empty container stackers, both of which belong to the handling construction machinery. The picking and stacking in the handling operation is mainly through the front fork (or attachment) of the vehicle. and gantry structure, the existing two types of engineering vehicles mentioned above are not equipped with operating height detection and corresponding safety monitoring, and basically do not have the functions of operating height limit alarm and vehicle speed limit protection. In actual work, if When the driver does not have good safety awareness and the operation is not standardized enough, there is a certain safety risk

[0003] For example: when the mast is carrying goods up and running at a high position, the driver’s sight will be blocked due to the obstruction of the front goods, resulting in an accidental collision accident; in addition, when the mast is continuously at a high position and the vehicle is running at high speed with load Due to the forward movement of the vehicle's center of gravity, emergency braking may cause serious accidents such as accidental rollover of construction vehicles
