Description
Technical Field

Background
The principle of the digital detonator, which is also called a digital electronic detonator, an electronic detonator or an industrial digital electronic detonator, is that an electronic control module is adopted to control the detonation process, and the detonation of the detonator is realized by adopting a control integrated module and driving an ignition head through the module. Compared with the traditional mode of adopting time delay ignition powder to detonate the detonator, the detonation timing precision of the digital detonator is incomparable to that of the traditional detonator, the ignition powder of the digital detonator is attached to the ignition bridge wire, and the control integration module controls the ignition bridge wire to heat so as to detonate the ignition powder, and then detonates the detonator. Whether the digital detonator is normally detonated or not and whether the ignition bridge wire is in fault or not play a decisive role, and the efficiency and the quality of detonator production are also concerned when the digital detonator is subjected to the detection of the ignition bridge wire fault during delivery.
The whole working process from networking to initiation of the digital detonator is controlled by an electronic module in the detonator, and the initiation of the detonator is finally realized by discharging through an ignition capacitor carried by a digital detonator board to drive an ignition bridge wire to heat, so that ignition powder attached to the ignition bridge wire is ignited, and then the detonator is ignited. If the bridge wire resistance of the ignition bridge wire of the digital detonator is too large, the ignition bridge wire cannot be heated to the ignition point of the ignition powder by depending on the energy of the ignition capacitor, so that the detonator fails to explode. How to identify whether the ignition bridge wire of the digital detonator is in fault is an important research direction for improving the qualification rate of the digital detonator. In the field of digital detonators, how to detect faults of ignition bridge wires of the digital detonators is not a safe and reliable method.
