Background
The electronic detonator uses the delay chip to replace chemical delay powder in the traditional detonator, and has the advantages of high delay precision, good safety, network detection and the like. When in use, the electronic detonator is required to be connected with a bus of the control equipment. The ID of each electronic detonator is stored in a chip of each electronic detonator, and in order to accurately control the corresponding detonator, the control equipment needs to acquire the ID of each electronic detonator through a bus.
