Background
The digital detonator has the advantages of controllable use area, delay accuracy, blasting networking flexibility and controllable blasting quality, and is widely popularized and applied in blasting construction of industrial and mining enterprises in recent years; however, in the practical application process of the digital detonator, the security loophole of process management control still exists: when the initiator is lost accidentally, illegal blasting can be carried out in a defined use area by illegal personnel by using the lost initiator; secondly, in the blasting operation field, after all the operators are required to leave the operation surface and evacuate to a safety zone by the operation safety specification, the digital detonator can be subjected to detection, delay setting, delay modification, delay releasing and blasting operation by the aid of the detonator; but the situation of irregular operation still exists under certain special conditions, when the operator does not leave the operation surface and leaves the safety zone, the digital detonator is detected, set in a time-delay way, modified in a time-delay way, given down in a time-delay way and detonated by the detonator, so that life safety threat is brought to the operator; therefore, how to solve the problems radically through the improvement of the technology becomes a problem to be solved for the popularization and application of the digital detonator.

In order to realize the purpose, the invention adopts the following technical scheme: an encrypted digital detonator initiator system and a safe operation control method are provided, wherein the encrypted digital detonator initiator system comprises an initiator, an encryption operation device and a secret Key, the encryption operation device is a computer with an encryption module arranged inside, and the secret Key is a USB-Key; the detonator is provided with a fingerprint acquisition device; the detonator comprises an authorization mode, a work preparation mode, a work mode and a detonation mode; when the detonator works, the modes are sequentially carried out, namely the next mode can be entered after the previous mode is finished; when the detonator works, the detonator firstly enters an authorization mode after being electrified, and under the authorization mode, the detonator is electrically connected with the encryption operation device, the encryption operation device is electrically connected with the secret key, and the detonator, the encryption operation device and the secret key work cooperatively to complete authorization operation on the detonator; before the authorization mode is completed, the operations of the work preparation mode, the work mode and the detonation mode are all in a shielding state, and the operations are invalid, so that unauthorized illegal persons can be prevented from operating the detonator; in the working preparation mode, the working mode and the detonation mode, the detonator works independently, namely the detonator can be separated from the encryption operation device and the secret key after finishing the authorization operation and is carried independently to enter the field for operation, and the detonator, the encryption operation device and the secret key are in a separated state, so that the condition that the detonator, the secret operation device and the secret key are lost together in the using process of the detonator is prevented; if the initiator is lost in the field use process, illegal personnel cannot use the initiator because authorized people in the initiator cannot be modified; in the detonation mode, the detonation instruction can be sent only after all the workers participating in the detonation are confirmed, so that management flaws in the detonation operation process are blocked by technical means, and all the workers leave the operation surface and are evacuated to a safety zone when the detonation operation is carried out, so that the problem of life safety threat to the workers due to irregular operation is fundamentally solved.
Further, the initiator performs an authorization operation in an authorization mode; when the initiator carries out authorization operation, the initiator is electrically connected with the encryption operation device, the encryption operation device is electrically connected with the secret key, the encryption operation device controls the initiator to input the fingerprint of an authorized person through the fingerprint acquisition device, namely, after the initiator completes the authorization mode operation, only the authorized person can start the initiator through the fingerprint; and after the fingerprint recording of the authorized person is completed, the initiator enters a work preparation mode.

Furthermore, after the construction of the blasting network is completed, in a working mode, an authorized person starts the detonator by fingerprints, and only after the fingerprints of all blasting operation personnel are authenticated, the detonator can be operated to carry out the operations of detecting, delaying setting, delaying modification and delaying release of the digital detonator, so that the situation that all the blasting operation personnel leave the working surface when the detonator carries out the operations of detecting, delaying setting, delaying modification and delaying release of the digital detonator is technically ensured; after the delayed discharging operation is finished, the detonator automatically enters a detonation mode.
Furthermore, in the detonation mode, an authorized person starts the detonator through the fingerprint, and can send the detonation instruction only after the fingerprint of all the blasting operation personnel is authenticated, so that the detonation instruction is technically ensured that all the blasting operation personnel leave the operation surface when the detonator sends the detonation instruction, and the life safety of the blasting operation personnel is ensured.
Furthermore, after the detonation operation is finished, the fingerprint of an authorized person in the detonator automatically fails, and the detonator automatically restores to the authorization mode, namely, the authorized person cannot start the detonator again through the fingerprint, so that the problem of misuse of the detonator possibly caused by the fact that the authorized person has the use authority of the detonator for a long time is prevented; after the initiator completes one work cycle from the authorization mode, the work preparation mode, the working mode and the initiation mode, the initiator automatically generates an initiator operation record report inside the initiator, the initiator operation record report is inquired and read through the encryption operation device, and when a blasting accident happens accidentally, the initiator is used for analyzing the accident reason.
Furthermore, in the work preparation mode and the work mode, after an authorized person starts the detonator through the fingerprint, the detonator automatically returns to the non-starting state when no effective operation is performed within one minute, and illegal operation of the initiator by the non-authorized person when the initiator is in the starting state for a long time after being started is prevented; and when the detonator does not have any effective operation within twenty-four hours, the detonator automatically restores to the authorization mode, so that possible management leaks of the detonator under the authorized state for a long time are prevented.
Further, in the detonation mode, after an authorized person starts the detonator through the fingerprint, the detonator automatically returns to the non-started state when no effective operation is performed within one minute; after fingerprint authentication of all blasting operators, when no detonation instruction is sent within ten seconds, the detonator automatically restores to a non-starting state; and when the detonator does not have any effective operation within twenty-four hours, the detonator automatically restores to the authorization mode, so that possible management leaks of the detonator under the authorized state for a long time are prevented.
