Degree.For example, as shown in Figure 3 includes the 1st group and the 2nd group of inductive detection module, judged using rising edge threshold value, and
When T1 is less than T2, the impulse waveform of inductive signal as shown in Figure 4, then it represents that the rotary switch is rotation counterclockwise.And
If T1 is greater than T2, then it represents that the rotary switch is to rotate clockwise.Equally, if being sentenced using failing edge threshold value
Disconnected, then when the inductance L1 for collecting the 1st group is equal to the failing edge threshold value, the time recorded at this time is T3；When collecting
When 2nd group of inductance L2 is equal to the failing edge threshold value, the time recorded at this time is T4.When T3 is less than T4, the 1st group is indicated
Inductance reach the failing edge threshold value first, then as shown in connection with fig. 3 include the 1st group and the 2nd group of inductive detection module,
The rotary switch is to rotate clockwise, if opposite T3 is greater than T4, indicates that the 2nd group of inductance reaches the failing edge first
Threshold value, the rotary switch are rotation counterclockwise.
