Embodiment one：
Fig. 2 shows a kind of simple statistics based on photoelectric sensor that a kind of embodiment of the utility model provides
The circuit block diagram of device, illustrate only and the relevant part of the utility model embodiment for convenience of description.
The light that pulse generation module described in the present embodiment is mainly made of pipe D1, D3 and D2, D4 two pairs of infrared receiving/transmissions
Electric transducer is realized.Each pair infrared receiving/transmission includes an optical transmitting set and an optical receiver to pipe.Counting module circuit is mainly by can
Inverse decade counter 74LS192 is cascaded to form.Display module is mainly completed to statistical value using eight segment numeral pipes
Display.It by north to south is " into " direction to define in Fig. 2, is " going out " direction by Nan Zhibei.Output terminal out1, out2 are during beginning
Low level.If count target is moved from " into " direction, when it blocks the infrared light of originator D1, output terminal out1 rises to height
Level, with the movement of count target, when it blocks the infrared light of originator D2, output terminal out2 rises to high level.Directly
The sensitive zones of D1 and D3 are left to count target, output terminal out1 recovers low level when receiving end D3 receives infrared light again；
Similarly, when receiving end D4 receives infrared light again, output terminal out2 recovers low level.Count module control logic circuit in the block
The time difference of the low and high level change produced by the use of two output terminals generates pulse signal CP1 counting up as 74LS192
Pulse input.Conversely, if count target is moved from " going out " direction, output terminal out2 first produces level change and output terminal out1 is first
Level change is produced, pulse signal CP2 subtracting as 74LS192 is generated also with the time difference of the two level changes
Count pulse input.So that count target " into " hour counter adds 1, " going out " hour counter subtracts 1, meets the plus-minus counting in two directions
