Fig. 2 is system works flow process figure of the present invention
Embodiment
As shown in Figure 1, by STC89C52 single-chip microcomputer [5] control total system, keyboard [10] can be used for time and the pattern that intelligent switch enters automatic mode is set as the man-machine interaction input equipment, the electrical work pattern of response opening and closing signal when particularly being in automatic mode.Clock chip [6] is used for the expansion single-chip microcomputer, can make things convenient for the system-computed intelligent switch to enter the time of duty and the time of hand switch pattern.The infrared ray of body surface emission sees through Fei Nier lens [2] and arrives infrared temperature sensor [1], infrared temperature sensor [1] receives infrared radiation, be converted into electric signal, because voltage signal is very faint, so need to realize that with the signal amplification circuit of amplifier [3] voltage signal amplifies, single-chip microcomputer can't Analog signals, need the sampling by analog to digital converter [4], quantize with process such as coding analog signal conversion to be become digital signal, sending into single-chip microcomputer [5] handles, if temperature is in the body temperature scope or descend and to reach predetermined value, trigger the infrared remote control key, infrarede emitting diode emissioning controling signal in the radiating circuit, phototriode in the receiving circuit on the electrical equipment receives infrared control signal, and carries out action through the effect formation pulse control executive circuit of amplifying circuit.Simultaneously, LCD [7] can be used for showing body temperature as the man-machine interaction output device, information such as work at present state
As shown in Figure 2, according to the function of each interface of single-chip microcomputer and the effect of each circuit, can determine the workflow diagram based on the intelligent switch of human body infrared temperature-test technology.Mentality of designing is initialize routine at first, will move clock during beginning shows and the liquid crystal display subroutine, the keyboard subroutine is regulated the time and date of clock chip [6] and the mode of operation of intelligent switch control apparatus response signal as interrupt service routine, simultaneously can import the time that enters automatic mode, when time value runs to the value of automatic mode setting, then start-up temperature is gathered subroutine, the body temperature numerical value that infrared temperature sensor [1] records is sent into amplifier and A/D converter processing, utilize the validity of judging the subroutine judgment data then, if Temperature numerical is in the body temperature scope, then single-chip microcomputer [5] is given control signal of output terminal, start infrared transmitter and send the electrical equipment start signal, be communicated to infrared remote receiver and open or enter specific mode of operation with control apparatus, record the temperature value that collects for the first time simultaneously, then utilize time delay subroutine, gathered every five minutes, amplify, the inversion temperature data once, and the difference of calculating real time temperature value and initial value, when temperature decline difference reaches 0.5 ℃, single-chip microcomputer [5] is given high level signal of output terminal, trigger the power key control remote appliance of infrared light telechiric device [8] and close or enter specific mode of operation, end temp is gathered subroutine simultaneously, when these instructions are carried out, do not influence the operation of clock subroutine and display subroutine.If the temperature data of gathering under the working method is not in the body temperature scope automatically, then system regards as invalid data, returns under the init state, reruns the temperature acquisition subroutine.So circulation is carried out, and can realize according to the actual requirements the automatic control to electrical equipment.
To be embodied as example the course of work of the present invention is described above, certainly, the present invention is not limited in above embodiment, according to above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the instructions, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
