A kind of pyrotechnics detonation control system and test method thereof

Abstract

The invention discloses an explosive detonation control system, which realizes the control of the explosive initiation through three-level control. The control system includes a control circuit and a protection and measurement system, wherein the control circuit includes a first relay, a second relay, and a third relay for controlling the on-off of the circuit, a current-limiting resistor connected in series with the relay, and a case ground for leakage. The discharge resistor for discharging static electricity; and the protection and measurement system includes multiple star meter sockets. By inserting the protection plug or the launch plug in the star meter socket, the on-off of the pyrotechnics control circuit can be controlled, and it can be used multiple times at any stage. Measure the detonation circuit, detonation sequence and bridge wire resistance of pyrotechnics.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an explosive detonation control system and a testing method thereof. Background technique [0002] The pyrotechnic device is a sailboard deployment separation detonation device commonly used on spacecraft. After the spacecraft enters orbit, it first needs to detonate the sailboard pyrotechnic device to realize the unlocking of the mechanism, the deployment of the solar panel, and supply energy for the spacecraft. [0003] Usually, before the launch of the spacecraft, a large-scale sail panel deployment test will be carried out to verify the correctness of the design of the explosive detonation circuit. Therefore, the design of pyrotechnics access is a key link in the safe and reliable design of spacecraft. Whether the design of pyrotechnics is reasonable and whether the verification is sufficient will directly affect the success or failure of the launch mission. [0004] The ...

AI Technical Summary

Problems solved by technology

[0004] The existing pyrotechnic detonation control system is limited by the test safety and test site, and it is difficult to carry out large-scale double-wing sailboard deployment operation, and the single wings need to be deployed separately. Therefore, it is necessary to improve the reliability and safety of pyrotechnics; in addition, aerospace It is generally difficult to carry out the final measurement before launching the arrow into the launch tower, which makes the test of pyrotechnics insufficient
