Abstract
The utility model belongs to a control circuit, and particularly relates to an ignition circuit with interlocking input and output. The ignition circuit comprises solid-state relays N1, N2, N3, N4, N5 and N6. The ignition circuit has the advantages that the ignition of an explosive device means that an output-end ignition bus is connected with an ignition output end through logic control, and then the explosive device can be ignited through voltage of the ignition bus. The output-end ignition bus is introduced into an input control end so as to realize interlocking of input and output; a loop of the input end is disconnected when the ignition bus has voltage so that the explosive device can not be ignited; and the explosive device can not be ignited by mistake even though any disturbing mode exists at the input end when the output-end ignition bus has no voltage.

Description of drawings
Fig. 1 is the firing circuit sketch map of a kind of input and output interlocking that the utility model provided.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
As shown in Figure 1, a kind of firing circuit of input and output interlocking comprises solid-state relay N1, N2, N3, N4, N5 and N6, wherein, and the solid-state relay JGW3023B that N1, N2 export for long closed contact; N3～N6 is the solid-state relay JGX36M of normally opened contact output; The IN+ of N1 and N2 is connected with a 3.3k Ω resistance respectively, and each 3.3k Ω resistance all is connected with the OUT+ of N3 and N5, and the IN-of N1 and N2 is connected with QF; The OUT+ of N1 and N2 is connected with the 5v power supply, and the OUT-of N1 and N2 is connected respectively with the IN+ of N3, N4, N5 and N6, and the IN-of N3 is connected with DH1_CPU; The OUT-of N3 is connected with the OUT+ of N4, and the IN-of N4 is connected with DH2_CPU, and the OUT-of N4 is connected with DH1+; The IN-of N5 is connected with DH1_CPU, and the OUT-of N5 is connected with the OUT+ of N6, and the OUT-of N5 is connected with the OUT+ of N6; The OUT-of N6 is connected with DH2+, and DH1+ is connected with DH2+.
QF takes off to plug with-B in separation and is connected, with bullet emission automatic disconnection; DH1_CPU and DH2_CPU be by 2803 control the GND_CPU signal, with 5V_CPU altogether; DH1, DH2 are the ignition signal of parallel connection; + B and 5V_CPU are independently.
The purpose of this circuit be take off touch QF and unplug before (i.e. bullet emission before), guarantee DH1, the output of DH2 no-voltage; After lift-off contact (QF) unplugs, connect GND_CPU successively, make+B connects with DH1, DH2, the realization purpose of lighting a fire through CPU control DH1CPU and DH2_CPU.
This circuit is a power amplification circuit, and with 5V input control+B output, the function and the characteristics of this circuit are following:
Can know by Fig. 1, realize that igniting needs two conditions: 1.+B is charged; 2. N3 and N5 have at least a relay closes and N4 and N6 to have a relay closes at least.This circuit makes this two condition interlockings through N1 and N2 relay, and whenever promptly do not meet accident the igniting situation:
Before taking off:
When+when B was charged, N1 and the work of N2 relay were broken off the input anode of N3～N6, even there are interfering signal in DH1_CPU or DH2_CPU, N3～N6 also can't be closed, and assurance+B and DH1, DH2 can't connect, and can't light a fire.When+when B is not charged, even there are interfering signal in DH1_CPU or DH2_CPU, the input conducting of N3～N6, DH1, DH2 and+B connects, but this moment+B is not charged, can't light a fire yet; In any case promptly, can not realize ignition function before taking off.
After taking off:
This circuit guarantees that the whichever relay output end with the short circuit or the mode failures even that opens circuit, relies on other relay work all can normally realize ignition function.
