Embodiment Construction

[0068] The present invention will be further described below with reference to the accompanying drawings.

[0069] Such as figure 1 figure 2 As shown, a four-point automatic leveling system based on a six-axis combined sensor is composed of an actuator 1, a controller 3, a six-axis combined sensor 4, a landing detection switch 6 and a laser ranging sensor 7;

[0070] The executive mechanism 1 is four electric cylinders, and the four electric cylinders are respectively arranged on the four corners below the adjusted platform 2 in a rectangular arrangement;

[0071] The six-axis combination sensor 4 adopts the six-axis acceleration gyroscope combination sensor developed by Kionix Company, whose model is KXG07 or KXG0708. At the intersection point, it is used to detect the current attitude of the adjusted platform 2 and send attitude information;

[0072] The ground detection switch 6 is installed on the end of the extension rod 5 of the electric cylinder, and each electric c...

Abstract

The present invention discloses a four-point automatic leveling system based on a six-axis combination sensor and a working method thereof. The system comprises a six-axis combination sensor, an execution mechanism, a landing detection switch, a laser rang finding sensor and a controller. The six-axis combination sensor is employed to obtain current attitude data in an Euler angle mode, and the coordinate transformation method is employed to calculate the expansion amount of the electric cylinder extension bar of the execution mechanism so as to simplify the expression method of leveling system attitude and an expansion amount calculation formula, reduce the system design difficulty and improve the system work efficiency.

Description

technical field [0001] The invention belongs to the technical field of attitude automatic leveling of a workbench. technical background [0002] At present, in order to improve the safety of construction and the reliability of operation, it is necessary to control the leveling of construction devices under specific working conditions, such as leveling of heavy vehicles, machine tool processing, anti-aircraft artillery control, offshore drilling platforms, parallel mechanisms, etc. [0003] The existing leveling methods mainly include three-point leveling, four-point leveling, and six-point leveling methods, etc. Among them, the three-point leveling method is simple and easy to implement, but it is very easy to overturn when subjected to external forces. However, the six-point leveling method has complex algorithms and variable leveling conditions, making it difficult to effectively control the leveling system. Therefore, the existing leveling methods generally use the four-p...
