Description

technical field [0001] The invention relates to the technical field of pyrotechnics, in particular to a digital electronic detonator control chip that is convenient for safety supervision and has high delay accuracy and safety reliability. Background technique [0002] At present, world famous manufacturers and enterprises such as Orica Company of Australia, AEL Company and Sasol Company of South Africa, DynamitNobel Company of Sweden, Davey BickFord Company of France and Asahi Kasei Industry Company of Japan have all developed electronic time-delay detonators and their detonation systems. Among them, Orica's electronic delay detonator can realize all programming from 0 to 15000ms at intervals of 1ms, and the delay accuracy is within 0.2ms when the total delay time is less than 100ms, and the error is less than 0.1% when the total delay time is greater than 100ms; Asahi Kasei Industrial Co., Ltd. The electronic delay detonator can set the delay at intervals of 1 ms within th...

Problems solved by technology

The detonator coding system regulates the production, sales and use of detonators, but cannot prevent the illegal use of detonators

Once the detonator explodes, it will be broken into fragments, and its "code" will no longer exist. It is impossible to trace the source of the detonator, which is not conducive to standardizing the use of the detonator, and cannot prevent the detonator from being detonated by criminals or major accidents caused by the negligence of practitioners and illegal operations. The stability of the society, so when designing the digital electronic detonator control chip, consider its traceability, and design the detonator chip to have its own identification code
