Electronic detonators are the main initiation method currently used in the field of explosives engineering. However, they cannot be used in classroom or experimental teaching due to their high risk and special control requirements. It is urgent to develop a safe, reliable and reusable simulation device. Based on the STC15 microcontroller technology, a kind of analog electronic detonator for teaching was designed and tested. The simulated electronic detonators can be manufactured by 3D printing technology an they have been successfully applied to detonator detection and detonation network simulation experiments. The analog electronic detonator is mainly composed of power circuits, detonator simulation circuits, and PCB boards. A pair of leads protruding from one end of the detonator are connected to the power supply. Then, the microcontroller control chip, the drive circuit and the acousto-optic simulator are powered by the power supply circuit. After being powered on, the microcontroller control chip can drive the acous-to-optic simulator device according to the written program to simulate the operation of the electronic detonators. Thus, adjustable delay times have been implemented. In addition, the real blasting scene can be simulated, the internal structure can be visually observed, and series parallel stable operation can be realized. Through the experimental teaching, students can understand the structure and characteristics of electronic detonators, master the detonator performance detection method and detonation network connection method. The new analog electronic detonators can fully mobilize students' enthusiasm of learning the “blasting safety” course, give full play to the subjective initiative, and effectively improve their practical ability.
