The principle of work of this radiation overproof prompts instrument:
Before pocket multi-functional radiation overproof prompts instrument is placed on equipment under test.
1, high-frequency signal analog to digital converter HF (high frequency, 10MHZ-3GHZ) antenna receives after the signal (75 decibels more than the microvolt) that exceeds standard, at first signal is decayed by resistance R I, promptly when outer signals is 75 decibels of microvolts herein signal intensity should be 50 decibels because the thresholding of IC1 is 50 decibels of microvolts.Enter 1 pin of IC1 integrated package through isolation capacitance C3 (1N) through the signal of overdamping.Export from 5 pin through inner amplification and frequency conversion (reducing by 256 times) back, through 12,13 pin of C6 (1000N) coupling back to ic chip 4, in IC4, amplify, from the output of 8 pin, through D5 detection and C24 filtering through shaping, become DC control voltage, send 19 pin of IC10 to, 10,12,13 human hair combing wastes by IC10 go out instruction then, and loudspeaker is sounded, corresponding pilot lamp is luminous, the warning lamp flicker.Finish the prompt facility that the high-frequency signal radiation exceeds standard.
2, low frequency signal analog to digital converter LF (low frequency, after 1HZ-10MHZ) magnetic antenna (100 millihenry) receives the radiation signal (75 decibels of microvolts) that exceeds standard, improve gain by magnetic antenna and enter 2 pin (1 millivolt of thresholding) that C10 (1000N) is coupled to IC2 again, export from 1 pin through the inner back of amplifying, be sent to 1 of ic chip 4 through D 61,2 pin amplify through inner shaping, export by 6 pin, by the detection of D6 and the filtering of C24, become DC control voltage, send 19 pin of IC10 to, it is luminous to send the corresponding pilot lamp of instruction by IC10 then, and loudspeaker is sounded, the prompt facility that the low frequency signal radiation exceeds standard is finished in the warning lamp flicker.
3, ultrasonic receiver US (20---80KHZ, ultrasound wave receive head) is when extraneous ultrasound wave is above standard (more than 60 decibels), and receiving signal that head just has, to make input signal intensity in the time of 60 decibels through the dividing potential drop of C27 and C28 be 1 millivolt.The signal that is attenuated is coupled to 2 pin of ic chip 3, export by 1 pin through inner amplification, to the detection of D66 and the filtering of C62, become DC control voltage, send 12,13 of IC6 to, export to 20 pin of IC10 again from 8 pin, IC10 sends instruction, and it is luminous to send the corresponding pilot lamp of instruction by IC10 then, and loudspeaker is sounded, the prompt facility that the ultrasound wave radiation exceeds standard is finished in the warning lamp flicker.
4, infrared detector UV (infrared ray, receiving tube) receives (more than the 3500 lumens) infrared ray that exceeds standard as UV, UV receiving tube resistance value will reduce, will reduce the parameter that changes R5 with the junction voltage of R5 this moment makes input at 3500 Lhr.s, voltage is 3v herein, 1 of IC6,2 pin voltages are lower than 3V, 3 pin of IC6 will be exported noble potential, and the filtering of the detection C26 of process D8 becomes DC control voltage, send 21 pin of IC10 to, it is luminous to send the corresponding pilot lamp of instruction by IC10 then, and loudspeaker is sounded, the warning lamp flicker.Finish the prompt facility that infrared radiation exceeds standard.
5, power source charges portion C HARGER: when the 9V power supply adaptor with after this machine is connected, by the stable 6V direct current of 7806 three-terminal voltage-stabilizings output, pass through C47 again, after the filtering of C48, becoming does not have the 6V of clutter power supply stably.The battery electric quantity deficiency of this moment is lower than 3V at the variable-resistance middle point voltage of VR2, and it is continuous with 1,2 pin of IC7, when 1, when 2 pin voltages are lower than 3V, the high point of 3,4,5 pin output position, this moment is by 3, R7 is delivered in the height point position of 4,5 pin output, D3, and the luminous expression of D3 is charged.Another road of 3,4,5 pin outputs to 4 pin of IC8 simultaneously, just begins after 4 pin of IC8 obtain noble potential by 3 pin output pulse current.This pulse current enters the base stage of Q1NPN triode after the R9 current limliting, the Q1 conducting, and Q2PNP triode conducting is simultaneously exported pulse constant current to battery charge by the collector of Q2.The C22 that links to each other with IC8, D2, VR1, R6 are the original papers of decision IC8 oscillation frequency.The resistance value that changes VR1 can change the size of charging current.Battery is full of when the charging voltage of battery two ends reaches 5.8V.1, the 2 pin voltage that feeds back to IC7 has surpassed 3V, and this moment, 3,4,5 pin of IC7 became the low spot position, and 4 pin of IC8 become behind the low spot position will the failure of oscillations, 3 pin no-outputs, and charging is finished.The IC7 of this moment is because 3,4,5 pin have become the low spot position, and 6 pin have just become high position, and the noble potential of 6 pin is by R8, and D4 is to ground, and the luminous expression charging of D4 is finished.At this moment charging indicator light, D3 be because of 3,4, the low spot position of 5 pin and extinguishing.
