Embodiment Construction
[0052] The photoelectric sampling device of the meter proposed by the present invention includes a light emitter; and a light receiver, the light receiver is arranged opposite to the light emitter and forms a light-irradiating area between the two; and, by the meter The base of the watch drives a rotating turntable, and the turntable is provided with a light-shielding part and a light-transmitting part, and the rotating motion of the turntable makes the light-shielding part and the light-transmitting part alternately pass through the light incident area. Sampling through-beam optical signal sampling solves the problem that light is easily interfered by external light in reflective optical signal sampling, reduces the difficulty of sampling signal identification, and requires the production process and assembly requirements of product parts.
[0053] The technical solutions of the embodiments of the present invention will be explained and described below in conjunction with the ...
