The civil explosion device can be registered and put on record in a public security civil explosion management system before leaving a factory, the registration information comprises parameter information, a manufacturer, a date of leaving the factory and the like of the civil explosion device, the public security civil explosion management system can verify according to explosive identification information by comparing ex-warehouse information, logistics information or project declaration information and the like, and feeds explosive attribute information corresponding to the explosive identification information back to the cloud server 1, and the cloud server 1 sends the explosive attribute information to the exploder 2 according to the identification information of the exploder 2. The attribute information of the explosive at least comprises information such as the type of civil explosion device, the detonation mode, the explosive capacity, the resistance of an ignition head, the safety voltage and the like.
After the detonator 2 receives the attribute information of the blasting product, the attribute information of the blasting product uses codes to represent different information contents, such as unit codes 0 and 1 or multi-bit codes abc and bcd and the like, if the blasting attribute information is multiple, multiple groups of identification codes are used to respectively represent the information contents, so that the detonator 2 can conveniently carry out corresponding blasting operation after being identified, for example, the attribute code + the identification code 0 in the charging attribute of the charging blasting attribute information represents that the attribute code + the identification code 1 has a charging function, and the detonator 2 can identify whether the digital detonator has the charging function or not after being read.

Or after the exploder 2 identifies whether the digital detonators have the explosion energy charging function, the exploder identification information is sent to the corresponding explosion modules, and the explosion modules are independently stored, so that the explosion identification information is grouped, and the first identification information group is obtained.
The initiation module comprises an inner energy storage initiation module 4 and an outer energy storage initiation module 5, and the initiation module comprises the following components:
a. internal energy storage detonation module 4
The blasting bus connected with the internal energy storage blasting module 4 is connected with a digital detonator or an electronic detonator in series or in parallel, the digital detonator or the electronic detonator is not provided with an energy storage capacitor, and the blasting bus 2 is in bidirectional communication with the digital detonator and sends a control signal or a blasting signal to the digital detonator. The initiation mode is that the whole digital detonator network is directly initiated by using power electricity, a large-capacity capacitor 11 is required to be arranged at the 2 end of the initiator, the initiation energy is provided by utilizing the instantaneous discharge of the large-capacity capacitor 11 so as to initiate the digital detonator, the direct current provided by the power supply 20 is converted into alternating current by adopting an oscillating circuit, the capacitor is charged after the voltage is boosted and rectified, the circuit is switched on after the charging voltage reaches a rated value, and the capacitor discharges to initiate the digital detonator or the electronic detonator on the blasting bus.

The blasting bus connected with the external energy storage blasting module 5 is connected with a digital detonator with a small-capacity capacitor in parallel, and the blaster 2 is in two-way communication with the digital detonator through the blasting bus and sends a control signal, an energy storage signal or a blasting signal to the digital detonator. When the initiator 2 is in two-way communication with the digital detonator, low-voltage power supply (such as not more than 5V) is kept for the digital detonator, so that the intrinsic safety is ensured. An electronic ignition element is arranged in the digital detonator, the electronic ignition element is a sensitive ignition agent coated with a thin resistance wire welded between a positive electrode and a negative electrode, the thin resistance wire is made of constantan or nickel-chromium material, the diameter of the thin wire is less than or equal to 0.02mm, the resistance value of the constantan wire is 0.7-1.5 omega, the resistance value of the nickel-chromium wire is 2.0-3.5 omega, when the access current of the two electrodes of the electronic ignition element is more than 0.15A, and the voltage drop of the resistance wire is more than 1V, the sensitive ignition agent is heated by the resistance wire and ignited to ignite.
After the initiator 2 sends an energy storage signal, a power supply bus voltage smaller than 50V is kept for the digital detonator, the energy storage capacitor is charged, after the voltage of the energy storage capacitor reaches a rated voltage, the initiator 2 sends an initiation signal, the microprocessor of the digital detonator receives the initiation signal and then reads the signal, and after the signal reaches a specified time, the microprocessor controls the electronic ignition element to discharge and ignite, and the initiation is ignited. The energy storage capacitor of the digital detonator provides an electronic ignition element for discharging and igniting, is a miniaturized patch capacitor which can be arranged in a detonator shell (the inner diameter is 6mm), and has the capacitance of less than or equal to 10 muf and the withstand voltage of less than 50V.
After the initiator 2 is powered on, if the initiator 2 has no operation for a certain period of time (for example, within 60 seconds), it can be determined that the operation is currently idle, and the program is automatically closed. Before detonation, the detonator 2 acquires the voltage value of a large-capacity energy storage capacitor or a small-capacity energy storage capacitor, and can detect the voltage value of the detonation capacitor. If the voltage of the capacitor is lower than a set value (such as 20V), which indicates that the capacitor is not charged enough and the success of detonation cannot be ensured, the program is halted and error is reported, so that error data can be collected and analyzed for specific reasons of non-detonation, and meanwhile, the safety evaluation is facilitated when the non-detonation time is processed. When the timing detonation is carried out, the voltage of the detonation capacitor is detected in real time, when the voltage of the detonation capacitor exceeds the full-charge capacitor voltage (for example, 8V) at any moment within a certain time (for example, 8 seconds) before the countdown is finished, the situation that the detonation capacitor is abnormally charged is shown, the program is halted and error is reported, and the situation that the false detonation is caused by abnormal boosting under the external interference condition is ensured not to occur.
Before detonation, the internal energy storage detonation module 4 or the external energy storage detonation module 5 collects blasting article identification information of all digital detonators connected into a blasting bus, and a plurality of identification information groups corresponding to the detonation modules are formed after the blasting article identification information is collected, so that a second identification information group is formed. And each identification information group in the first identification information group and the second identification information group is provided with a group label corresponding to the detonation module, the second identification information group of the same group label is respectively compared with the first identification information group, if unmatched blasting identification information appears in the first identification information group or the second identification information group, the situation that unregistered digital detonators are mixed in the first identification information group or the second identification information group, or the situation that the digital detonators are missed occurs, the program is halted, and an alarm is given. The method can realize that the same initiator 2 can simultaneously initiate civil explosion devices of different types and initiation modes, can greatly reduce the initiation cost, and lays a foundation for the initiation of multiple types.
