example 1

[0097] A1=35°, A2=358°;

[0098] N2 / N1=10, R=360°*(N1 / N2)=36°, M=[35° / 36°]*36°=0;

[0099] A0=0+358*(1 / 10)=35.8°, δ=35°-(35° / 36°)*36°=35°;

[0100] Since (δ-R / 2)*(A2-180) is greater than 0, A=A0=35.8°.

example 2

[0102] A1=35°, A2=358°;

[0103] N2 / N1=20, R=360°*(N1 / N2)=18°, M=[35° / 18°]*18°=18;

[0104] A0=18+358*(1 / 20)=35.9°, δ=35°-[35° / 18°]*18°=17°;

[0105] Since (δ-R / 2)*(A2-180) is greater than 0, A=A0=35.9°.

[0106] In this way, through the cooperation of the first angle detection unit 60 and the second angle detection unit 70, combined with the angle ruler measurement algorithm, the precise measurement of the angle can be realized.

Abstract

The invention discloses an angle ruler and an angle calculation method, the angle ruler comprises a first measuring arm and a second measuring arm, the first measuring arm is pivoted with the second measuring arm, the angle ruler further comprises a speed increasing device, wherein the speed increasing device is connected with the first measuring arm and is arranged at the pivoted part of the first measuring arm and the second measuring arm, and the speed increasing device can increase the speed of the rotation of the first measuring arm and output the speed of the rotation of the second measuring arm; a first angle detection unit which can detect the rotating angle of the first measuring arm relative to the second measuring arm and output a first signal; a second angle detection unit which can detect the rotation angle of the output end of the speed increasing device relative to the first measuring arm and output a second signal; and a data processing unit which is configured to process the first signal and the second signal and output a final result of angle measurement of the angle ruler. According to the angle ruler, the speed increasing device is arranged on the first measuring arm, the final angle value is determined by measuring the rotation angle value of the speed increasing device and the rotation angle value of the first measuring arm, and accurate measurement of the angle can be achieved.

Description

technical field [0001] The invention relates to the technical field of angle measurement, in particular to an angle ruler and an angle calculation method. Background technique [0002] The angle ruler is a tool for measuring angles. There are two measuring arms on the angle ruler, which are a fixed arm and a rotating arm. Fit the fixed arm to one side of the angle to be measured, and then rotate the rotating arm so that the rotating arm It is attached to the other side of the angle to be measured, and the sensor on the angle ruler detects the rotation angle of the rotating arm, and the angle value of the angle to be measured can be measured. The existing angle ruler only uses a group of sensors to detect the rotation angle of the rotating arm and measure the angle value, but the measurement result is not accurate enough and the measurement accuracy is not high. [0003] Therefore, it is necessary to propose an angle ruler with accurate measurement results and high measureme...
