Design of Programming Electronic Delay Detonator

A design proposal for a kind of online programming electronic detonator is introduced in this paper. The safety and reliability of the design is analyzed, and then the methods for realizing the design proposal are exploited. The structure of the electronic detonator, the internal control circuit structure diagram, and part of the software flowchart, are presented. The time programmable increment step of 1 millisecond is arrived at, while the programmable delay time of this system ranging from 1 to 12000 milliseconds is obtained. Taking its safety and reliability, its accuracy in delay time, and its easy of use, into account, the online programming electronic delay detonator proposed in this paper will be extensively applicable to complicated blasting engineering in the future.
