As shown in Figure 1, detonation velocity meter comprises pulse producer 1, pulse receiver 2 and calculation element 3.
Pulse producer 1 is launched a plurality of continuous electromagnetic impulses with certain frequency.As shown in Figure 2, a kind of cycle of launching for pulse producer 1 is the oscillogram of the square wave of T.A plurality of continuous impulses of pulse producer 1 emission comprise the first pulse P1 and the second pulse P2.The time interval between the second pulse P2 and the first pulse P1 is nT, and n is the integer more than or equal to 1.
Transmission line is axial arranged along explosive.One end of transmission line is embedded in the explosive column, and the other end links to each other with pulse producer 1, is used to propagate a plurality of continuous impulses of pulse producer 1 emission.Transmission line can adopt concentric cable, and for example, the concentric cable in 75 Europe etc. do not receive external interference with protection burst transmissions process.
In the process of explosive charge, be embedded in transmission line in the explosive column along with the blast of explosive gradually fusing shorten, the variation of length of transmission line is the length of explosive detonation.Through calculating transmission line length variations amount within a certain period of time, can obtain the average explosion velocity of explosive in this time period.When this time period enough in short-term, can be similar to and think that this average velocity is the real-time explosion velocity of explosive.
