A design proposal about a kind of electronic delay detonator based on AVR single chip was introduced in this paper. The realization method was explained, at the same time, the safety and reliability of the electronic delay detonator was analyzed. The structure of the electronic delay detonator, the intemal control circuit structure diagram and part of the software flowchart were given. The experiment showed that the range delay time of the electronic delay detonator is from 0 to 12 000 milliseconds, and the time programmable increment step can be set online according to the engineering need. With the safety and reliability, the accuracy in delay time and easy of use, the electronic delay detonator will be extensively applicable to complicated blasting engineering of high quality.
