The invention provides an angle detecting device, method and system. The angle detecting device comprises a first sliding ring, a second sliding ring, a rotary shaft, a first sliding sheet and a second sliding sheet, wherein the first sliding ring and the second sliding ring are arranged at an interval in the axial direction of the rotary shaft, the projection of the first sliding ring in the radial plane of the rotary shaft is provided with a first central angle, the projection of the second sliding ring in the radial plane of the rotary shaft is provided with a second central angle, the sum of the first central angle and the second central angle is larger than or equal to 360 degrees, and an opening of the first sliding ring and an opening of the second sliding ring are opposite in direction. The first end of the first sliding sheet is connected with the rotary shaft, the second end of the first sliding sheet is electrically connected with the first sliding ring in a slideable mode, the first end of the second sliding sheet is connected with the rotary shaft, and the second end of the second sliding sheet is electrically connected with the second sliding ring in a slideable mode. According to the angle detecting device, method and system, 360-degree continuous detection can be achieved, namely the defect that in the prior art, angles of dead zone positions can not be detected is overcome, the detection continuity and the detection integrity are achieved, and the angle detecting device has the advantages of being simple in structure and low in cost.
Description
technical field [0001] The present invention relates to the field of angle detection, and more particularly, to an angle detection device, method and system. Background technique [0002] In the high-end field of industrial equipment, many mechanical equipment need to achieve 360° unlimited continuous rotation to complete the corresponding actions. Therefore, the detection and control of the rotation angle of the equipment is very important. [0003] At present, there are mainly two ways to realize the detection of the rotation angle: (1) use a rotary encoder to complete; (2) use a single slip ring rotary potentiometer to complete. Among them, the rotary encoder is relatively expensive and easily damaged, so it will increase the cost of the equipment. [0004] Combine below figure 1 , the working principle of the single slip ring rotary potentiometer detecting angle in the prior art will be described in detail. Such as figure 1 As shown, the two ends of the slip ring 10...
