2, conventional addressing electronic switch is excited by processor addressing, and mode of excitation is changed to Ignition Logic and excited by the present invention,
Safety more stable than conventional addressing electronic switch, while mechanically and electrically the two-in-one design of sub switch makes its letter from inside to outside
The structure and layout of perforation gun joint are changed；
If 3, a detonation module attempts detonating capsule but do not succeed, although he still has, it can be defined as
" unhealthy " switch, signal can be conducting to that above him " health switch " and continue task at this time, once it detects last
One " health " switchs, and the detonation route in switch can be closed, and excitation (is preset as 2 in voltage input to coupled detonator
Second/detonator), switching system meeting suspend mode after excitation, once inputting negative voltage again, above procedure can be repeated until whole
Detonator is excited.
