The input end of the reference voltage module of the initiating explosive device detection system is connected with a power supply end; the reference voltage module is used for providing reference voltage; the input end of a control signal input module is connected with a control signal input end to provide a detection signal; the input end of a switch module is connected with the reference voltage module and a control signal input module to control a detection circuit to be started and shut down; the input end of a load detection module is connected with the output end of the switch module; the load detection module is used for detecting the connection state of the load module; and the output end of an isolation module is connected with the load module for protecting the detection circuit. Through an online way, the real-time detection of a load resistor connection state is realized, a whole process does not need to change an equipment state and does not need artificial participation, and the problem of the real-time detection of the load resistor connection state in a whole initiatingexplosive device is effectively solved.

Description

technical field [0001] The invention relates to the field of pyrotechnics, in particular to a detection system and method for pyrotechnics. Background technique [0002] 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 generally used as ignition components of pyrotechnic devices. The activation of electric detonators is mainly by ignition. Determined by current and power, electric energy is converted into heat energy through a bridge wire with a certain resistance value, heating the ignition powder around the bridge wire and detonating the main charge, and the action is completed instantaneously. The load is an independent part in the ignition system, and the reliability of its connection with the discharge circuit directly determines whether the system works normally. Therefore, it is the key to ensure the reliability of the system t...

Problems solved by technology

However, after the pyrotechnic equipment enters the working state, it is impossible to manually detect the connection state. Therefore, how to quickly determine the connection state of the load has become an important problem to be solved.
