Description

A detonation signal checking apparatus, and a system including the same The present invention relates to a detonation signal inspection device and a system including the same, and more specifically, to a detonation signal inspection device capable of generating a first lamp driving signal in a delayed state and being electrically isolated from the input terminal of the detonation signal based on a detonation signal input in a detonation signal inspection mode, and generating a second lamp driving signal according to power supplied from a power supply unit in a self-inspection mode, and a system including the same. There are detonators for performing various missions. Since detonators are single-use devices that cannot be reused, there are limitations to using the actual detonator to determine whether the signal applied to the detonator is normal. Therefore, there is a need to develop an inspection method and device that can determine whether a detonation signal is normally applied without using an actual detonation device.
