But this kind of device must require the device to be detected to rotate at least one complete circle. In some application environments, if the device to be detected is only rotated 30 degrees, the magnet may not be able to touch the Hall proximity sensor, and it is impossible to judge. turn around

Embodiment Construction

[0108] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0109] Such as image 3 As shown, a rotation direction detection device includes a rotation direction detection device 300 and a processor 400 . The rotation direction detecting device 300 is used to be arranged on the detected component, detects the rotation data through several Hall sensors 14 , and submits it to the processor 400 . The processor 400 judges the rotation direction of the detected component by executing the program instruction set. Obviously, the processor 400 is connected to each Hall sensor 14 . The arrangement and structure of the Hall sensor 14 on the rotation direction detection device 300, refer to figure 1 .

[0110] Such as figure 1 As shown, the rotation direction detection device 300 includes a first panel 11 and a second panel 12 arranged parallel to each other. The first panel 11 is used to connect the detected component, an...

Abstract

The invention discloses a rotation direction judgment method and device and a rotation direction detection device. The rotation direction detection device comprises a processor and a rotation direction detection device. The rotation direction detection device comprises a first panel and a second panel which are arranged in parallel. The first panel can rotate around the center of the first panel and is provided with magnetic steel arranged in an arc shape. The second panel is provided with at least four Hall sensors which are arranged at equal intervals in the circular circumferential direction. The processor is connected with the Hall sensors, determines the rotation direction of the first panel through a rotation direction judgment method executed by a program instruction set, and then determines the rotation direction of a tested part connected with the first panel according to the rotation direction of the first panel. Compared with the prior art, the rotating direction of a smallangle can be detected, and the anti-interference capability is high.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a sensor for detecting rotation orientation. Background technique [0002] In the prior art, a three-axis gyroscope sensor is usually used as a sensor related to orientation detection. But when judging the rotation orientation, the three-axis gyro sensor is not suitable. Patent document JPH01124770A discloses a method and device for detecting rotation. In this patent document, two Hall proximity sensors are used to determine the order in which the magnets rotate to determine the direction of rotation. But this kind of device must require the device to be detected to rotate at least one complete circle. In some application environments, if the device to be detected is only rotated 30 degrees, the magnet may not be able to touch the Hall proximity sensor, and it is impossible to judge. turn around. Contents of the invention [0003] The problem to be solved by the present invention is t...
