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.
The utility model provide a kind of can compatible various modes level the circuit design of (for example TTL signal, 100V are used for pulse signal, 2000V that explosion triggers and are used for pulse signal that the high-power switchgear pipe triggers or the like) output.This design both can compatiblely trigger multiple systems, can also isolate by light isolation and electricity and realize the separate of different system and prime is controlled protection partly.
The signal of telecommunication of prime is carried out gating earlier, utilize electrooptic conversion module to convert a certain road light signal to, trigger corresponding output circuit by this light signal again, this method adopts the light isolation to isolate with electricity and has realized the separate of each output circuit, has also realized the optional of various modes output.
Fig. 1 need to select the level of output by the human-computer interactive control module, the MCU controller is judged this selection, analyze the module which uses, by the control multi-channel gating device, the triggering signal of outside input is connected to the electrooptic conversion module generation light signal of this road correspondence, this light signal is converted to the level signal of 15V again via Optical Fiber Transmission and electrooptical device, trigger the output module on this road, obtains the correspondent voltage waveform at output port.Multi-channel gating device is example with AD7501, by controlling the level of 3 logic input pins, 1 input signal can be connected to one of 8 passages, just can realize the selection of 8 kinds of patterns,, then the AD7501 cascade be used to get final product if the model number that needs surpasses 8, use multi-channel gating device in addition, can respond the burst pulse input signal (such as peak value 20V, the pulse signal of pulsewidth 1 μ s) of higher level, this be common MCU can not respond.By designing different output modules, realized that just the multi-mode of output is optional.That designs in each output module has an electric isolating circuit, can prevent each interchannel phase mutual interference, has both realized the compatibility to multiple systems, has also made things convenient for the dilatation of system.Electrooptic conversion module HFBR-14XX is connected the device data that adopts Agilent company with peripheral circuit and the light path of photoelectric conversion module HFBR-24X2.Also can select other electrooptic conversion module and photoelectric conversion module during design, what unique needs were followed is that the light signal that two kinds of modules are transmitted must mate.For example use HFBR-1412 and HFBR-2412 respectively, they all are to use the light of 820nm wavelength, at this moment will select the monomode fiber of 820nm just can realize that the signal of light path transmits.In addition,, the power supply VCC of HFBR-24X2 is designed to 15V DC power supply (the highest 18V) for the strengthening system antijamming capability, its 6 pin output be the 15V level signal.
Fig. 2 is output module design circuit figure, described output module comprises that the photoelectric conversion module output is connected with switching tube (Q1) base stage, second voltage stabilizing didoe in parallel (D2) between the base stage of switching tube and emitter, first resistance (R1), first voltage stabilizing didoe (D1) negative electrode, the switching tube collector electrode, electric capacity (C1) is connected with DC power supply (V+), electric capacity (C1) other end, second resistance (R2), the 3rd voltage stabilizing didoe (D3) is linked in sequence, the circuit that transformer (T1) input and second resistance (R2) and the 3rd voltage stabilizing didoe D3 form is connected in parallel, second resistance R 2 is connected with the 3rd voltage stabilizing didoe D3 anode, transformer T1 output is connected with the 4th voltage stabilizing didoe D4, the first voltage stabilizing didoe D1 anode, the second voltage stabilizing didoe D2, first resistance R 1, switching tube Q1 emitter, the 3rd voltage stabilizing didoe D3 negative electrode, the transformer input altogether.DC power supply V+ from the 15V level signal trigger switch pipe Q1 that photoelectric conversion module converts, makes capacitor C 1 pulse transformer T1 discharge to capacitor C 1 charging, is exported by the 4th voltage stabilizing didoe D4 through after the voltage transitions.The first voltage stabilizing didoe D1 plays the voltage protective effect to C1 among the figure; the second voltage stabilizing didoe D2, R1 shield to Q1; the common second voltage stabilizing didoe D2 is the voltage stabilizing didoe of a 15V, and second resistance R 2, the 3rd voltage stabilizing didoe D3 pulse transformer T1 play afterflow.The level magnitude of output has been determined in the design of DC power supply V+ and pulse transformer T1, for example requiring the module output level is 2000V, the no-load voltage ratio that can design V+ and be 400V, pulse transformer T1 is 1: 5 (other a compound mode also can), and other device is selected according to correspondent voltage parameter in the circuit.In this circuit, pulse transformer T1 realizes the undersuing upset is positive pulse, has also constituted electric isolating circuit together with the 4th voltage stabilizing didoe D4.
Multi-channel gating device is realized the selection of MCU controller to passage, and make to use up to isolate and combine the separate of each passage of realization with the electricity isolation, convenient to the compatible of multiple systems and the dilatation of self, MCU controller control multi-channel gating device is realized the multiselect one of passage, each passage all will be received on the output port by electric isolation module separately at last together through the process of electrical-optical-electricity.
