When the explosive is detonated, detonation waves fuse a group of insulating target lines close to the detonator, the wound insulating target lines are instantly conducted, so that a common line and a target 1 line maintain an extreme time passage, and therefore a target 1 wiring terminal of the detonation velocity meter can detect high level output by a public end, and an internal timer of the detonation velocity meter is started; when detonation waves reach the second group of target lines, the winding copper wires are fused and instantly conducted, the wiring terminal of the target line 2 of the detonation velocity meter can also detect the high level output by the public end, the detonation velocity meter stops timing at the moment, a time t (unit s) is obtained, and finally the detonation velocity meter displays the detonation velocity calculation result, and the detonation velocity calculation formula is as follows: v=s/t, unit m/s.
When the actual detonation velocity is detected, the detonation velocity instrument is free from detonation velocity data output after detonation of the explosive often occurs due to the conditions of the detonation velocity instrument, the signal wire is damaged and the like, and an operator cannot conveniently and quickly detect the fault reason at low cost.
