Abstract

The invention relates to the technical field of observation and control and discloses a discharge curve customizable circuitry for detonating an initiating explosive device through a large-capacity capacitor. The discharge curve customizable circuitry comprises an input voltage control module, a feedback control module, a capacitor discharge output module and a current signal amplification module. The capacitor discharge output module comprises an integral control module, and the large-capacity discharge capacitor, an output resistor and a power switch pipe which are in series connection on the same circuit. The input voltage control module is connected with the input end of the feedback control module and the output end of the current signal amplification module. The input end of the integral control module is connected with the output end of the feedback control module, and the output end of the integral control module is connected with the power switch pipe. The current signal amplification module and the output resistor are in parallel connection and then in series connection with the capacitor discharge output module.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a large-capacity capacitor detonation pyrotechnic discharge curve customizable circuit system. Background technique [0002] At present, pyrotechnics are important action execution devices, which are widely used in civil and military fields, especially in the aerospace field. In practical applications, electric detonators are commonly used as ignition elements of pyrotechnic devices. The activation of the electric detonator is mainly determined by the ignition current and power. The electric energy is converted into heat energy through the bridge wire with a certain resistance value, which heats the ignition powder around the bridge wire and detonates the main charge, and the action is completed instantaneously. Electric detonators require a large ignition current and instantaneous power to achieve normal detonation. The traditional pyrotechnic ignition circuit ...
