Digital electric detonator ignition system based on biometric identification technology

Abstract

The invention discloses an electronic digital detonator based on the biological identification technology and an initiation system, comprising a detonator initiation system and a group of electronic digital detonators controlled by the detonator initiation system for blasting. The lead (a bus for both power-supply and communication) of each electronic digital detonator is connected in parallel with a control output terminal of the initiation system; the detonator initiation system is provided with a key device and a multiple biological identification unit simultaneously; the ID code authorized for initiating the detonator is arranged in the detonator initiation system; an integrated circuit system and an energy-storage capacitor are respectively arranged in each electronic digital detonator; a unique authorized ID code is stored in the integrated circuit system of the detonator; and only if the two ID codes are identical mutually the initiation can be carried out correctly. The control output terminal of the detonator initiation system is connected with each electronic digital detonator through the lead for both power-supply and communication.

Description

technical field [0001] The invention relates to an electronic digital detonator detonation system based on biological identification technology. Background technique [0002] The biometric identification system (Biometric Identification Technology) samples the biological characteristics, extracts its unique features and converts them into digital codes, and forms these codes into feature templates. When people interact with the identification system for identity authentication, the identification system obtains its features and It is compared with the profile template in the database to determine whether there is a match, so as to accept or reject the person. [0003] Biometric identification technology is currently the most convenient and safe identification technology. It does not need to remember complex passwords, nor does it need to carry keys, smart cards and the like. Biometric technology identifies the person himself, which is the safest and most convenient.
