摘要（英）：

The invention provides an initiating explosive device resistance measurement circuit capable of automatically calibrating a multipath initiating explosive device circuit. The multiple initiating explosive device circuit comprises multiple initiating explosive device working branches connected in parallel, and each initiating explosive device working branch is provided with an initiating explosive device resistor and an initiating explosive device working switch. The initiating explosive device resistance measurement circuit comprises a constant current source, a digital signal processor, a calibration circuit, a resistor measurement circuit, a resistor measurement parallel circuit and the like. The constant current source is used for providing current for initiating explosive device resistance measurement. The calibration circuit is used for determining errors of the resistor measurement circuit. The resistor measurement circuit and the resistor measurement parallel circuit are used for determining measurement of the initiating explosive device resistor of each initiating explosive device working branch. The digital signal processor is used for recording and determining the true value of a to-be-tested initiating explosive device resistor. The initiating explosive device resistance measurement circuit achieves independent measurement of multipath initiating explosive device resistance in order, and is high in precision and safety.
