Problems solved by technology

There are many technical ways to realize the sequential detonation explosion network, such as the sequential detonation explosion network with multi-detonator structure, which realizes sequential detonation by controlling the detonation time interval between detonators. The control time accuracy of this sequential detonation method is poor, generally greater than 10 microseconds; the sequential detonation explosion network of the multi-blade detonator structure can also achieve sequential detonation by controlling the detonation time interval between the detonators. This sequential detonation method has good time control accuracy, up to 100ns level, but The cost of the shock plate detonator is high, and it is difficult to be widely used in engineering; another is to use the explosive network structure of the explosive charge line, and control the length of the explosive charge line to control the detonation wave output time interval, so as to realize the multi-point output detonation wave Sequential detonation, the design cost of this kind of sequential detonation network is low, and the control accuracy can range from 100 ns to tens of microseconds, but this kind of detonation network occupies a large space and requires a relatively large area of ​​the detonator
It can be seen that there is currently no high-precision, low-cost, small-area sequential detonation explosion network
