Specific embodiment
For convenient for those skilled in the art understand that technical solution of the present invention, technical solution of the present invention is combined have below
Body embodiment is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of rotating part position identification device, rotating part 30 is provided with multiple
Switching part switches over multiple switching parts by the rotation realization of rotating part 30, the rotating part position identification device
Including mounting base 20, rotating part 30 and N number of optoelectronic switch 41, mounting base 20 makes energy between other components for connecting other components
Enough generate relative motion；N is the positive integer not less than 2；Since optoelectronic switch 41 only identifies and cannot identify two states, know
Not Biao Shi optoelectronic switch 41 detected object, cannot identify indicate optoelectronic switch 41 do not detect object；Therefore for multiple
The single optoelectronic switch 41 of switching part is not able to satisfy requirement；
The rotating part 30 is installed on mounting base 20 by rotary shaft 50, and rotating part 30 is enable to generate relative to rotary shaft 50
Rotary motion meets the requirement of 30 position of rotating part switching；The rotating part 30 is provided with M group transmittance section, institute along rotary shaft 50
It is different to state M group transmittance section, M group transmittance section respectively corresponds 30M turned position of rotating part, and M is just whole not less than 2
Number；N number of optoelectronic switch 41 is installed on mounting base 20, and N number of optoelectronic switch 41 identifies any one group of transmittance section jointly；M<

State identification puts in order；For example, identifying after N number of optoelectronic switch installs according to the first photoelectric switch state, the second light
The sequence of electric switch ... N photoelectric switch state identifies 30 position of rotating part；Also it can pass through the second optoelectronic switch, the first photoelectricity
Sequence identification 30 position of rotating part of switch, third optoelectronic switch ... N optoelectronic switch；
First optoelectronic switch identify/cannot identify, and the second optoelectronic switch identify/cannot identify ... and the identification of N optoelectronic switch/
It cannot identify, 2 Nth power kind state of N number of optoelectronic switch composition；M group transmittance section respectively correspondsIn kind state
Different M kind state；Guarantee that the M group transmittance section of setting can respectively correspond M state of N number of optoelectronic switch composition；For
Rotating part 30 needs the switching of multiple setting positions, to guarantee the M group light transmission for the information and setting that N number of optoelectronic switch 41 identifies
