Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Global design: the Transistor-Transistor Logic level signal that this adapter requirement can be converted to standard with the signal of telecommunication and the light signal of relative broad range, and built in light electric isolating circuit, and can be effectively complete electrical isolation be carried out in the front and back end of triggering the loop, solve the problem of triggering system because of ' ' false triggering of crosstalking.As shown in Figure 1, many level adapted device is made up of signal condition module, electrooptic conversion module and photoelectric conversion module.The signal condition module functions is through overdamping, amplitude limit, current limliting and pulse shaping the conditioning of the signal of telecommunication more than the 5V to be the Transistor-Transistor Logic level signal; Electrooptic conversion module is made up of light emitting head and peripheral protective circuit, and major function is to be light signal with electrical signal conversion; Photoelectric conversion module is made up of light-receiving head and peripheral protective circuit, and major function is that light signal is reduced to the signal of telecommunication;
The electric triggering signal of input is sent into the signal condition module through connector, adjusted signal is sent into electro-optical conversion circuit conversion, light signal after the conversion is directly exported or is sent into the opto-electronic conversion loop with the light triggering signal of input and change, after signal connector output.
Physical circuit design: as shown in Figure 2, the signal condition module comprises: R0 is that build-out resistor, R1 position first divider resistance, R2 are that second divider resistance, the 3rd resistance R 3, diode D1 and first capacitor C 1 constitute amplitude limiter circuit; D2 is a voltage stabilizing didoe; The 4th resistance R 4 is swung protective resistance for weakening; The 5th resistance R 5, second capacitor C 2 and chip U1 form pulse former.Resistance R 0 is the build-out resistor of 50 Ω.First resistance R 1 and second resistance R 2 are divider resistance (being the potentiometer of 10k Ω), for preventing that interference signal from causing false triggering, voltage ratio is regulated according to input signal, R1 increases along with the increase of input signal, the second divider resistance R2 reduces along with the increase of input signal, wherein the build-out resistor R0 and the first divider resistance R1, the circuit parallel connection that the second divider resistance R2 forms, the input signal and the first divider resistance R1, the parallel circuits input that build-out resistor R0 forms connects, the 3rd resistance R 3 in the amplitude limiter circuit, diode D1 output, first capacitor C 1 is connected with voltage stabilizing didoe D2 output four end nodes, voltage stabilizing didoe D2 input, first capacitor C, 1 other end ground connection, the 3rd resistance R 3 other ends, chip U1 the 16 pin, the 5th resistance R 5 one ends connect+the 5V power supply simultaneously, the 5th resistance R 5 other ends are connected with second capacitor C 2, second capacitor C 2 is connected with U1 the 14 pin, diode D1 input, the first divider resistance R1 and the second divider resistance R2 tie point, the 4th resistance R 4 three end nodes connect, the 4th resistance R 4 other ends are connected with chip U1 first pin, the 5th resistance R 5 is connected with U1 the 15 pin with second capacitor C, 2 links, U1 the tenth three-prong is as system's output, build-out resistor R0 and second divider resistance R2 output head grounding in parallel.
