In concrete application process, acquisition control circuit of the present utility model comprises conversion process and safety protective circuit, arranges constant-current source and provides constant current for circuit.Acquisition control circuit electrical schematic diagram is as shown in Figure 2.
Conversion process circuit is for being transformed to magnitude of voltage by the tested explosive parameter resistance value gated through variable connector card, and the A/D end for multifunction card gathers automatically；Safety protective circuit is for guaranteeing the safety in the automatic gatherer process of priming system parameter, and the most most crucial problem is to ensure that the electric current flowing through tested explosive resistance is less than the value required, in safety range.
Constant-current source of the present utility model is by the D/A control realization in multifunction card, and its circuit diagram is as shown in Figure 3.Its core is an amplifier, according to the operation principle of this amplifier, can provide the D/A magnitude of voltage of input and the relation between audion 5V3 output electric current I, be shown below:
(1+k)V+ - k·VDA=VC-I·R14
Wherein: k is amplifier amplification, it is not difficult to draw, k=1.2 in this utility model example；V+ is the input of amplifier forward, is 10V in this utility model example；VC is input power, is 20V in this example；R14=240Ω；VDA is D/A output voltage；I is that constant-current source exports electric current.
So, can show that the relation that in this utility model example, D/A output voltage VDA and constant-current source export is according to above formula:
I=[VC+k·VDA-(1+k)V+]/R14=5VDA-25/3(mA)
In this example, during in view of fire-working article test, it is desirable to the electric current flowing through tested explosive resistance is less than 10mA, to guarantee being perfectly safe of test process, the output of constant-current source is set as 8mA, then the D/A that can be calculated needs is output as:
