Abstract
The utility model relates to an infrared ray intelligent counter which comprises an infrared transmitting circuit, and an infrared receiving circuit, wherein, the infrared receiving circuit is connected with a counting circuit; the output terminal of the counting circuit is connected with a display circuit; the counting circuit adopts a single chip computer; the infrared receiving circuit is connected with the input terminal of the single chip computer; besides connected with the display circuit, the output terminal of the single chip computer is also connected with a speech circuit through a relay; a normally open contact of the relay is connected between the power supply terminal and the triggering terminal of the speech circuit. The utility model has a wide counting range and can generate similar speech sounds, such as welcome, etc. The utility model can be used in occasions, such as markets, supermarkets, etc. for making statistics of the passenger flow volume. In addition, the utility model can also be used for making statistics of vehicles running on highways, counting pieces on production lines, etc.
Description
Technical field
The utility model relates to a kind of electronic counter, particularly relates to a kind of infrared counting device.
Technical background
Counter on the market generally all adopts the simulation counting circuit, and counting region is less, can not adapt to the counting work of occasions such as big flow through-current capacity such as market.In addition, existing counter all only has tally function, can not satisfy people's needs.
Summary of the invention
It is big and have an infrared counting device of phonetic function that the purpose of this utility model provides a kind of counting region.
For achieving the above object, the utility model adopts following technical scheme: a kind of infrared ray intelligent counter, comprise infrared transmitter and infrared radiation receiving circuit, infrared radiation receiving circuit is connected with counting circuit, the output terminal of counting circuit is connected with display circuit, counting circuit adopts single-chip microcomputer, infrared radiation receiving circuit is connected with the single-chip microcomputer input end, the single-chip microcomputer output terminal is except that being connected to display circuit, also be connected to sound circuit by relay, the normally opened contact of relay is connected between the power end and trigger end of sound circuit.
Described sound circuit is made up of speech chip, driving circuit and loudspeaker, and driving circuit is made up of resistance R 2, R3 and triode Q2, and the Music Clip output terminal connects triode Q2 base stage by resistance R 3, and triode Q2 collector meets loudspeaker SP.
Between single-chip microcomputer output terminal and relay, be connected to amplifying triode Q1.
The utility model is owing to adopt single-chip microcomputer as counting circuit, therefore the counting region of this counter can reach 0～99999, counting region is wide, and when the utility model is used to measure number, can send similar speech sounds such as " welcome ", can be used on occasions such as market, supermarket the passenger flow quantitative statistics.In addition, the utility model can also be used for reckoning by the piece etc. on the statistics, production streamline of dealing vehicle on the highway.
Description of drawings
Accompanying drawing is depicted as circuit theory diagrams of the present utility model.
Embodiment
The infrared transmitter EM and the infrared radiation receiving circuit REC of this infrared ray intelligent counter are prior art, no longer disclose its detailed circuit schematic diagram.The output terminal of infrared radiation receiving circuit REC meets single-chip microcomputer 89C2051.The clock circuit that crystal oscillator Y2, capacitor C 6, C7 constitute is connected with the input end of clock of single-chip microcomputer 89C2051, for single-chip microcomputer work provides clock signal.Resistance R 1 is formed interrupt circuit with diode D and is connected with single-chip microcomputer external interrupt int0.Power Vcc connects the single-chip microcomputer reset terminal by the reset circuit that resistance R 3, capacitor C 8 constitute, for single-chip microcomputer provides electrification reset.Single-chip microcomputer 89C2051 output terminal is succeeded electrical equipment J1 by the driving circuit of being made up of resistance R and triode Q1, and the normally opened contact of relay J 1 is connected between the power end Vcc and trigger end YING of speech chip T in the sound circuit.Sound circuit is made up of speech chip T, driving circuit and loudspeaker SP, and driving circuit is made up of resistance R 2, R3 and triode Q2, and the Music Clip output terminal connects triode Q2 base stage by resistance R 3, and triode Q2 collector meets loudspeaker SP.Sound circuit is used for producing such as similar voice such as " welcome ".Single-chip microcomputer 89C2051 output terminal XSK, RXD, TXD also are connected to display lcd, are sent here the counted data signal and are shown for people's record by single-chip microcomputer and check.
Its principle of work is: infrared transmitter and receiving circuit are in a straight line during use, and radiating circuit is in the ultrared state of emission always.When people or thing by the time, infrared ray is blocked, at this moment infrared radiation receiving circuit detects infrared ray and is blocked, and sends a request signal to single-chip microcomputer 89C2051.Single-chip microcomputer will add 1 automatically, and be presented on the display module.Relay J 1 action simultaneously, the normally opened contact closure couples together VCC and YING port, and speech chip T is connected, and makes loudspeaker SP send the sound of " welcome ".
