Description

technical field

[0001] The invention relates to the design field of an engineering civil detonation system, in particular to a multi-channel pulse ignition laser detonation system. Background technique

[0002] At present, engineering civil detonating equipment and systems basically all use electric squibs as ignition devices. However, the wires used in the electric detonation tube and the electric detonation system have the possibility of coupling high-frequency electromagnetic pulses and triggering pyrotechnics by mistake, and the electronic devices used in the electric detonation system are complicated in manufacturing process, high in cost, and difficult to guarantee reliability. In view of the above-mentioned safety problems of the electric detonation system, the research and engineering of the laser detonation system, as a new detonation mode, has been paid more and more attention.

[0003] From the current use situation, it can be seen that the multi-channel pulse ig...
