Description

Technical Field

[0002] In recent years, with the continuous development of the economy, the demand for explosives in fields such as mining and infrastructure construction is relatively large, and the country is also constantly promoting the development of the industry. During use, industrial detonators (fire detonators, electric detonators, and explosive detonators) are gradually being eliminated by the country due to their high risk factors. At the same time, electronic detonators must be vigorously developed, and electronic detonators need to be connected to the detonating device before detonation so that the detonation can be controlled by the detonating device.

[0003] Before using the detonator, it is also necessary to perform status detection on its internal components (such as the micro switch for safety protection and the detonating wire for transmitting the explosion signal) to ensure the safety of the use process. However, the current detection method is to use the red and black test leads of a multimeter to touch the pins to directly measure whether there is a short circuit between the pins to determine whether the micro switch or detonating wire inside the detonator is in good condition and effective.
