The control circuit is composed of an intermittent infrared emitter which can automatically adjust horse power, an infrared receiver, a delaying amplitude inspecting circuit and a speaker device. An infrared transmitting apparatus is an orientating intermittent adjusting emitter which can automatically adjust horse power. An emitting head is arranged in an orientating metal tube base which is arranged at the head of a universal lifting device. The utility model achieves the controlling purpose by the amount of reflected infrared rays received by the receiver and whether the receiver receives reflected infrared ray. The monitoring device has the advantages of simplicity and reliability, and can be used for monitoring the existence and the distance of various objects.
Description
The utility model belongs to family expenses health care electrical installation, the particularly a kind of infrared ray sitting posture monitoring desk lamp that can remind the bad people's correcting sitting postures of sitting posture automatically.
The student learns anxiety at present, and workload is big, because the seat appearance is incorrect, causes most student eyesight to descend, and influence is work in the future; On the market a kind of infrared observation lighting device appears now, this device is received with infrared ray by the infrared ray emission to be formed, because of its infrared ray emission does not have automated power to regulate, when ambient light illumination changes, the detection distance changes, and is forbidden, and its infrared ray emission is not the directional transmissions at intermittence, the infrared light emission pipe is in running order always, and the service time of infrared emission tube is shorter; RF transmitter from the distance of monitoring object, highly, direction is all unadjustable, its precise control, reliability does not reach requirement, volume is big, uses inconvenience.
In view of this, how to design a kind of infrared monitor, direction, the height and distance of its infrared ray emission can be adjusted arbitrarily, the infrared ray transmitting power is adjusted in variation with ambient light illumination automatically, guarantee the reliability and the practicality of monitoring device, whole device lifetime is long, reliability height, the wound motivation place of grinding of the present utility model just.
Designer of the present invention and applicant on the basis of feasibility study repeatedly, get generation of the present invention by means of being engaged in the practical experience that electron controls technology is researched and produced for many years eventually.
At the deficiencies in the prior art; the purpose of this utility model is the directed monitoring device of a kind of infrared ray sitting posture of design; it possess distance, highly, direction can regulate arbitrarily; succinctly convenient and practical; be combined into infrared ray seat appearance monitoring desk lamp with lighting; it has automatic monitoring, reminds the function of correcting sitting postures, vision protection.
The purpose of this utility model is achieved in that the utility model is made of desk lamp, base, RF transmitter and infrared receiver, feature is that emitting head is installed on the universal adjusting device, universal adjusting device is installed on the base, and RF transmitter is connected by electric wire with emitting head; Universal adjusting device can be elevating lever or coiled pipe, and RF transmitter is provided with the power auto-adjusting circuit and the square-wave generator circuit constitutes, and infrared receiver is provided with and receives indicating circuit and time-delay amplitude limiter circuit.
The direction of the utility model emitting head, highly, the distance be adjustable; During work, the directional ir line at intermittence of emitting head emission is aimed at correct seat appearance people's head, and infrared ray is after the head reflection; receiver is received the reflected infrared ray signal; make control circuit not have control level output, the sound equipment alarm set does not ring, when people's sitting posture departs from the tram; the infrared emission signal reduces or does not have; after the integration time-delay, control circuit output control level makes the sound equipment alarm set send the sound; remind the people to rectify seat appearance, vision protection.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model schematic appearance;
Fig. 2 is the utility model embodiment circuit theory diagrams.
Referring to Fig. 1 and Fig. 2, the utility model is a kind of infrared monitor, is combined into infrared ray seat appearance monitoring desk lamp with lighting device, and it has lighting dimming desk lamp 1, universal adjusting device 2, ornament 3, emitting head 4 and control circuit to constitute.Its control circuit comprises RF transmitter and infrared remote receiver, but it is characterized by transmitter and be provided with a transmitting power auto-adjusting circuit and square-wave generator circuit, emitting head places in the directed base, base places the universal adjusting device head, base can have the material that intercepts the infrared ray effect to constitute by metal etc., makes the infrared ray directional transmissions.Modulate emission is made up of special use emission IC 1, transmitting tube D1, and power conditioning circuitry is made up of triode Q1, adjustable potentiometer W, capacitor C1, photo resistance R1.The square-wave generator circuit is made of amplifier A1, triode Q2, capacitor C2 and resistance R 2-R8; Receiver is made of infrared ray receiving integrate circuit IC3, and light emitting diode D3, resistance R 9 are formed the reception indicating circuit, and capacitor C3 and R10-R12 form the time-delay amplitude limiter circuit, and IC 4, loudspeaker DY form the sound equipment alarm set.
Integrated IC1 of transmitter adopts BA5104, amplifier integrated package to adopt LM358, receives an ic chip 3 usefulness RPM6938, audio manifold block IC4 CHB6612.
This circuit working process is as follows:
When square-wave generator A1 is output as low level, triode Q2 colelctor electrode output high level, this level control emission IC 1 is not worked, and transmitting tube is not launched infrared ray.When square wave is sent out device A1 main and is output as high level, triode Q2 colelctor electrode output low level, this level control IC 1 makes infrared emission tube send the infrared signal of modulation, this signal is owing to intermittently produce, infrared emission tube is not in duty always, can prolong its service life significantly; Infrared signal reflects by after receiving an IC3 receiving demodulation through correct seat appearance people's head, the 3 pin output low levels of IC3, and the luminous indication of light emitting diode D3 receives signal, diode D4 conducting, capacitor C3 level is zero.1 pin of prison width of cloth device A2 is output as low level, audio ic IC4 not electric and do not work, expression people seat appearance is proper.Incorrect when people's seat appearance, bow, torticollis, when leaving, receiving the infrared reflection signal that an IC3 receives will reduce or not have, 3 pin of IC3 are exported high level.Light emitting diode D3 does not work; diode D4 ends; power supply is through 3 chargings of 10 pairs of capacitor C of resistance R; the 1 pin output high level of prison width of cloth device when capacitor C 3 charging levels are higher than 2 pin level of prison width of cloth device; be added in and make its work on the audio ic IC4; loudspeaker DY sends the sound, reminds the people to rectify seat appearance, vision protection.The effect of photo resistance R1 is: cause when receiving change of sensitivity when ambient light illumination changes, can regulate the infrared ray transmitting power automatically, guarantee that circuit monitoring accurately and reliably.This monitoring device is simple, reliable, can be used on that various objects have or not, in the far and near monitoring.
In sum, basis is novel can utilize simple structural design, can effectively improve the reliability of service life and device work, and its practical effect is significantly improved.Obviously originally novel is the new design of a kind of novelty, progress and dark tool practicality.The above is this novel specific embodiment and the know-why of being used, the equivalence that the novel conception of Ruo Yiben is done changes, when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, all should be in this novel scope, explanation hereby.
