Abstract

The invention provides an angle measuring device which comprises a sensing turntable, N sensing units and a controller, wherein N annular regions are formed on the sensing turntable, 2<N-1> metal strips are arranged on each annular region at equal intervals in the clearance of 2<N-1> units, and each metal strip covers one unit; each sensing unit corresponds to one annular region to scan the metal strip on the annular region; the controller calculates the rotation direction and rotation angle of the sensing turntable according to the detection of the N sensing units to the metal strips on the corresponding annular regions; and M and N are integers greater than or equal 1. The angle measuring device provided by the embodiment of the invention is simple in hardware, low in cost and convenient for installation. Furthermore, the angle measuring device can be realized just by using a simple sensor, such as a proximity switch, therefore, the shielding property, reliability and maintainability are higher and the harsh working condition at the construction time of engineering machinery can be met.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an angle measuring device, a measuring method and a pump truck with the angle measuring device. Background technique [0002] With the continuous improvement of sensing technology, the requirements for automation and intelligence of many mechanical equipment are also increasing. However, automation and intelligence are inseparable from sensors, so it is particularly important to choose the right sensor. In many equipment, the angle value is a very important parameter, especially in equipment with mechanical arms, such as concrete pump trucks, cranes, etc., the rotation orientation of the turret directly affects the position of the center of gravity of the equipment, so the detection rotation The angle of rotation of the tower is significant. In modern mechatronic systems, encoders or special motors, such as resolvers and inductive synchros, are generally used f...
