C1, C3, C4, C6 and C7 all adopt monolithic capacitors; c2 selecting high frequency ceramic capacitor; c5 and C8 both adopt aluminum electrolytic capacitors with the withstand voltage value of 16V.
VL1 selects SE303A or PH303 type infrared light emitting diode; VL2 was a green high brightness LED with a diameter of 5 tnm.

The infrared receiving counting circuit consists of an infrared receiving amplifying circuit, a monostable trigger circuit and a counter, when an electronic element product (a moving object) does not enter an infrared monitoring area, the infrared receiving circuit can receive a modulated infrared light signal emitted by VL1 and output a high level, and the counter does not count. When the product passes through the infrared monitoring area to block the infrared light emitted by VL1, the infrared receiving circuit outputs a symmetrical square wave signal. After the signal is inverted and amplified by V2, the monostable trigger circuit A is triggered and inverted, the steady state is changed into transient state, and the infrared receiving circuit outputs high level. After the delay of 4-5 s, the monostable trigger circuit is recovered to be in a steady state, the infrared receiving circuit is changed from a high level to a low level, the monostable trigger circuit is triggered to turn over, and the infrared receiving circuit outputs the high level. After a delay of 10ms, the infrared receiving circuit changes from high level to low level, and generates a positive pulse with a width of 10ms, so that the counter counts once and VL flashes once. The above process is repeated continuously, i.e. each time a product passes through the infrared light monitoring zone, the counter counts and the reading of the counter records the total amount of production on duty.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that the changes in the shape and principle of the present invention should be covered within the protection scope of the present invention.
