the input trigger circuit of flashing light described in the present invention is routine techniques, and its effect is when flashing light triggering work, exports a signal to CPU, informs that its flashing light is in triggering work state.
1) the specific works principle of the guide number of flashing light described in the present invention testing circuit is as follows:
when flashing light triggers and normally works time, its flashing light electric capacity meeting repid discharge, now flashing light shows as quick-flash.When flashing light does not have triggering signal, it does not work, flashing light capacitor fast charging, therefore by detecting the charge and discharge of flashing light electric capacity, can differentiate that whether flashing light is in sudden strain of a muscle, and recording flashing light guide number by CPU.
specifically: when flashing light does not have a triggering signal, by resistance R1, R2, diode D1, electric capacity C1 form charge circuit, electric current detects the input of optocoupler G1 without guide number, so guide number detects optocoupler G1 not conducting, exports high level signal to CPU;
when flashing light has a triggering signal, by resistance R1, R2, guide number detects optocoupler G1, electric capacity C1 forms discharge loop, and guide number detects optocoupler G1 conducting, and output low level signal is to CPU, when CPU receives and records flashing light capacitor discharge, guide number detects the quantity of the output low level signal of optocoupler G1, differentiates the guide number of flashing light with this.
2) the specific works principle of the fault of flashing light described in the present invention and temperature protection state detection circuit is as follows:
time flashing light does not dodge when triggering flashing light, the operating state of flashing light can be judged by the voltage detecting flashing light electric capacity two ends.
specifically: when no-voltage on flashing light electric capacity, so flashing light is in temperature protection state, now fault detect optocoupler G2 not conducting, output low level signal is to CPU;
when flashing light electric capacity there being voltage, so flashing light is in malfunction, now fault detect optocoupler G2 conducting, and exporting high level signal to CPU, CPU is whether have fault by the height of judgement as above-mentioned input signal if detecting flashing light.
advantage of the present invention is:
1. this gas flashing light state detection circuit provided by the invention, it can realize the function that flashing light guide number detects, and export flashing light guide number in time by serial port, convenient inquiry in time, guarantee when the flashing light flash of light life-span will use up with this, provide for a rainy day, carry out in time and more change jobs.
2. this gas flashing light state detection circuit provided by the invention; it has flashing light fault and temperature protection status detection function simultaneously; when having triggering signal when there being flashing light but do not dodge; people can be allowed to inquire the state of flashing light in time by serial communication, thus take corresponding strick precaution and maintenance measures immediately.
