Design and application of digitally-programmable delay-time microchip in detonating system

A novel digitally-programmable delay-time microchip is introduced in this paper, which is based on detonating system. In order to make the detonating system more safety and reliability, C-MBUS is proposed in this paper. The programmable delay-time detonator can get power and data from Logger simultaneously. As a conclusion, the programmable delay time of this microchip ranges from 1 millisecond to 10000 milliseconds using the dedicated programming device, and the time programmable increment step can reach 1 millisecond. With its safety and reliability, its accuracy in delay time and its easy use, it will be extensively applicable to complicated blasting engineering of high quality.
