Based on above high-voltage signal detection alarm circuit and the Intelligent bracelet with this circuit, utility model works principle is described in detail;
A kind of high-voltage signal detection alarm circuit that the utility model embodiment proposes and have the Intelligent bracelet of this circuit, effectively can carry out alarm for high voltage to the high-tension apparatus in default sensing range or electric wire, Keep Clear-High Voltage in prompting, prevents electric shock accidents from occurring.
To divide into described bistable multivibrator for edge D flip-flop, described first switching tube Q1 is MOS semiconductor field, second switch pipe Q2 adopts NPN type triode, 3rd switching tube Q3 is PNP type triode, 4th switching tube Q4 is NPN type triode, described 4th resistance R4, described 5th resistance R5 and described 9th resistance R9 is current-limiting resistance, presetting and detecting high-voltage signal is 220V, 50Hz signal, when being within 0.5 meter in the default sensing range of default detection, the principle of work with the Intelligent bracelet of high-voltage signal detection alarm circuit is as follows:
220V is had near the Intelligent bracelet with high-voltage signal detection alarm circuit, 50Hz high-tension electricity, and distance is when being 0.5 meter, antenna ANT will receive 220V, the mains frequency signal of 50Hz, this signal is through described first resistance R1, first electric capacity C1, second resistance R2, 3rd resistance R3, after 3rd electric capacity C3 and the second electric capacity C2 frequency-selecting, add to the grid of the first switching tube Q1, after the amplification of the first switching tube Q1 and second switch pipe Q2, make the 3rd switching tube Q3 saturation conduction, now, the clock pins CP of edge D flip-flop and data pins D becomes high level from low level, edge D flip-flop triggers, described edge D flip-flop pin Q exports high level, described 4th switching tube Q4 conducting, warning device (can think loudspeaker) BL starts working, point out high-tension electricity dangerous.
When there being high-voltage signal near described Intelligent bracelet is not felt, described 3rd switching tube Q3 not conducting, the clock pins CP of described edge D flip-flop and data pins D is low level, described edge D flip-flop does not work, described edge D flip-flop pin Q output low level, described 4th switching tube Q4 not conducting, loudspeaker BL does not sound.
It should be noted that, in described Intelligent bracelet, also include circuit debugging calibrated section; This debugging calibrated section can arrange sensing range by regulating slide rheostat R6, namely, second switch pipe Q2 emitter voltage V1 can be made to be set in by regulating slide rheostat R6 to make Intelligent bracelet near the live wire (phase line) about 0.5 meter of 220V or far away apart from 10,000 V hi-line 2 meters time, protection against electric shock Intelligent bracelet sends alarm sound.
The utility model forms the testing circuit to 200V, 50Hz high-voltage signal by low cost edge D flip-flop and antenna and frequency selection network, and simply, cost is lower in technology realization; Wherein, judge and report to the police to be completed by digital circuit edge D flip-flop due to final signal, the high-tension electricity testing circuit controlled relative to existing central processing unit and simulation judge that it is highly sensitive for high-tension electricity circuit, and it is fast that signal triggers reaction velocity; And allow to trigger at CP to add input signal in a flash before coming due to described edge D flip-flop, like this, the time that input end is disturbed shortens greatly, the possibility being disturbed wrong report just greatly reduces, so the circuit anti-interference of edge D flip-flop formation is stronger thus, work in actual working environment more stable, reliable; Also because the circuit of the utility model design is devices at full hardware circuit, do not use programmable central processing unit to control, its cost is lower, and makes Intelligent bracelet be provided with the function detecting high-voltage signal fast.
The foregoing is only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., be all included in protection domain of the present utility model.
