Embodiment Construction
[0017] As shown in Figure 1, an angle detection device has a reading disk 1, and ten reading scales 8 from 0 to 9 are arranged on the reading disk 1 at intervals of 36°, and the reading disk 1 is connected to the detection flow through a transmission device 5 6. Corresponding to the reading disk 1, there is also a detection disk 2. The reading disk 1 is provided with a signal mark 3, and the detection disk 2 is provided with a signal detection point 4. The signal detection point 4 on the reading disk 1 is detected. Combining different signal marks, the angular rotation position of the reading disk 1 is fed back to the control unit 7 .
[0018] The distribution of the signal marks 3 on the reading disk 1 and the distribution of the signal detection points 4 on the circumference of the detection disk 2 can be in the following three ways:
[0019] Method 1: As shown in Figure 2, four fan-shaped areas with central angles of 54°, 54°, 126°, and 126° are sequentially set on the circ...
