The invention belongs to blasting supply producing technology field, which relates to a modification to electron detonator controller. It includes disturbance resisting circuit, voltage adjusting circuit, communication interface, energy storing capacitance, electron switch, firing device, control unit, clock circuit. Its character lies in: it has a decoding circuit working under control of the control unit; the electron ID code of the detonator is stored in the electron ID 251 of the decoding circuit. The invention makes the production, use, and management convenient, restrains the illogically use and illegal use of detonator, thus it solves the safety problem of detonator loss.
