One is connected to the signal output end of each channel of the channel switching circuit, the signal input end of each channel of the channel switching circuit is connected to the signal output end of the constant current source, and the controlled end of the channel switching circuit is connected to the On the drive signal output terminal of the single chip microcomputer.

Description

technical field [0001] The invention relates to a detection device for resistance and insulation state of pyrotechnics. Background technique [0002] Before the rocket is launched, the resistance and insulation status of the circuit in the rocket's ignition device should be tested. The general term for disposable components and devices that are filled with gunpowder or explosives, burn or explode after being stimulated by the outside world to ignite gunpowder, detonate explosives, or perform mechanical work is called pyrotechnics, so it is also called "pyrotechnics". "Detection. Since the number of endpoints that need to detect resistance and insulation status in actual work is very large, and pyrotechnics are the most sensitive part of the system, their safety and reliability directly affect the safety and reliability of the weapon system. The amount of detection tasks is very large, and manual testing is prone to misoperation, so a device is needed to automatically compl...
