The invention can realize the priming of the fault detection of abnormal circuit resistance and display fault information.

Description

Technical field: [0001] The invention relates to a detonation device and method for pyrotechnic products, in particular to a multi-circuit electric detonator detonation method and device with a self-check function and a line fault detection function. Background technique: [0002] Since the advent of the electric detonator, it has been widely used in the military and civilian fields. However, due to the danger and non-repeatability of electric detonator initiation, very high requirements have been placed on the reliability of the detonator initiating device. Broadening and increasing complexity (such as multi-channel precise delay detonation technology) puts forward new and higher requirements on the electronic control technology of electric detonators. The rapid development of electronic technology, embedded microprocessor technology, fault diagnosis and detection technology, and information technology has greatly promoted the improvement of the degree of intelligence, automatio...
