Description

Intelligent inductor

Technical field

The utility model relates to the electronic switch series products, specifically detect moving of people or object and control the switching of power supply, a kind of novel saves energy automatic switch, i.e. intelligent inductor, by the design of one wire system live wire power supply circuits, but load perception and resistive.

Background technology

At present, the toilet of office building, dwelling house, institutional settings and hotel guest-room, laboratory and other places adopt manual gas shut off control power supply, and some adopts sonic-opticalcon trolled switch and human induction switch in addition.Manual gas shut off is opened easily and is forgotten and close; Sonic-opticalcon trolled switch is to need sound source just to work, turn-on power, as the sound of thunder sound, honk and other high-decibels etc., and sonic-opticalcon trolled switch all can be worked, turn-on power; The detection of human induction switch is formed detection source by pyroelectricity probe and Fresnel lens, when detecting the mobile of people is signal source, switch is just worked, turn-on power, as everyone knows, Fresnel lens is made up of sensitive volume and blind area, moves in the blind area as the people, and switch is surveyed and can't be worked less than signal source.So above type of switch has been brought great inconvenience and waste electric energy to use.

Summary of the invention

In order to overcome the deficiency of existing switch, the utility model provides a kind of intelligent inductor, this intelligent inductor can detect the people and enter from the toilet or come out, thereby the signal source that detects makes automatic conducting of switch or powered-down automatically, brings great convenience to the user.

The technical scheme that its technical problem that solves the utility model adopts: form by power circuit, signal deteching circuit, counting circuit and output circuit.Power circuit is made up of capacitance-resistance, diode, voltage-stabiliser tube, and signal deteching circuit is made up of infrared emission and receiving tube, and counting circuit is made up of internal structure and the peripheral component of CPU, and output circuit is made up of triode and relay.After the signal source that infrared emission and receiving tube receive, be transported to CPU, CPU is interrupted, begin to calculate, the signal source that CPU receives according to infrared emission and receiving tube is successively judged moving of people, and whether indoor have a people, sends control signal by output circuit turn-on power or deenergization by CPU.

The characteristics of this intelligent inductor are the interference that can not be subjected to any signal, the toilet as long as someone enters or comes out, intelligent inductor just detects signal source, conducting or power cutoff, thereby produced the function that opens and closes automatically, so just bring great convenience, meet the requirement that China advocates energy-efficient society simultaneously to people.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

See also Fig. 1, the utility model is a kind of novel intelligent inductor, by power circuit, signal deteching circuit, counting circuit and output circuit are formed, power supply circuits: a route R1, C1, D1, D2, D3, D4, D5, D7, C2, C5, C6, C7 forms, R1, the C1 resistance-capacitance depressurization is through D1, D2, D3, after the D4 rectification, receive the positive pole of voltage-stabiliser tube D7 through C2 by D5, C5, C6, the power supply VCC that C7 filtering produces, another road is after relay is connected, and there is the pressure reduction of 6.8V at the D8 two ends through D1, D2, D3, receive the positive pole of voltage-stabiliser tube D7 through C2 by D5 after the D4 rectification, C5, C6, the power supply VCC that C7 filtering produces.Signal deteching circuit: penetrate pipe D9, D10 and infrared transmitting tube D13 and form and (perhaps directly adopt two reflective infrared switch D9, D10 and reflecting plate to form by two infrared connecing, as when adopting two reflective infrared switches and reflecting plate, remove D13, R6 gets final product), 2,3 of D9 meets power supply VCC, the output of 1 pin signal connects INT0 input 6 pin of single-chip microcomputer u1 through

resistance R

13,2, the 3 pin power supply VCC of D10, the output of 1 pin signal connects INT1 input 7 pin of single-chip microcomputer U1 through resistance R 4.One end of D13 infrared transmitting tube meets power supply VCC through resistance R 6, another termination UI output 11 pin.Counting circuit: by reset circuit, clock circuit and single-chip microcomputer U1 form, and C8, R9 form reset circuit, and crystal oscillator P1 and C9, C10 form clock circuit, and 10,20 pin of single-chip microcomputer U1 connect power supply, and output 9 pin connect output control and connect on the Q1 through R10.Output circuit: form by resistance R 4, R10 triode Q1, Q2, relay K 1, R10 is connected with the Q1 base stage, the collector electrode of Q1 is received VCC through R4, the collector electrode of Q1 is received on the base stage of Q2, the grounded emitter of Q1, Q2, the collector electrode of Q2 is received an end of relay coil, and the relay coil other end is received on the VCC.

The utility model is installed in the left side or the right side of door, when the people passes through the front of infrared emission and receiving tube, the detected signal source of intelligent switch, be transported to

input

6,7 pin of CPU, make the break sequence of CPU according to interrupt source signal, judge the direction of motion of people or object, calculate the quantity of turnover by CPU, when counting is zero, the 14 pin output control signal of CPU is given triode Q1 by R10, reaches the break-make of control relay, relay conducting energized when being output as 0, when being output as 1, relay disconnects and cuts off power supply.This circuit has the delay cut-off function, has reached power savings.
