Abstract

The invention discloses an overturning control method, an overturning control apparatus, an overturning control system, and construction machinery. The overturning control method comprises: determining the current overturning determination line of the construction machinery, wherein the current overturning determination line comprises at least one of the overturning lines of the construction machinery, and the overturning lines are connection lines between various supporting points of the construction machinery; determining the current overturning coefficient of the construction machinery relative to the current overturning determination line; and by comparing the current overturning coefficient to an overturning pre-warning threshold, judging whether the construction machinery is in an overturning danger state. According to the present invention, the driver can be timely and effectively reminded to drive carefully so as to reduce the possibility of the occurrence of the overturning accident; the advantages of simple operation and reliable control are provided; and the driver can real-timely grasp the supporting state of the vehicle through the method, the apparatus and the system of the present invention so as to well perceive the vehicle, such that the vehicle can be well controlled, and the occurrence of the danger can be avoided.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a method, device, system and construction machinery for overturning control. Background technique [0002] As a kind of flexible and convenient construction machinery, truck-mounted cranes are widely used in stations, warehouses, docks, construction sites, field rescue and other places. [0003] When the truck-mounted crane is working, the outriggers and tires share the loading and hoisting load. There are many support points, and there is a problem of rigid-flexible joint support, and the total weight of the vehicle and the position of the center of gravity will change according to the loading status of the vehicle. , Therefore, it is difficult to obtain its specific rollover stability performance from the theoretical aspect. However, truck-mounted cranes usually need to carry out long-arm working conditions. When the hoisting weight is large, if the operator blindly lifts...
