Detonating control system for initiating explosive device and test method thereof

Abstract

The invention discloses a detonating control system for an initiating explosive device, thereby realizing controlling of detonating of an initiating explosive device by three-level control. The control system comprises a control circuit and a protection and measurement system. The control circuit comprises a first relay, a second relay, a third relay, a current-limiting resistor, a casing ground,a bleeder resistor for discharging static electricity, and a protection and measurement system; the first relay protection and measurement system, the second relay and the third relay are used for controlling on-off of a circuit; the current-limiting resistor is connected with the relays in series; and the protection and measurement system comprises a plurality of star catalogue sockets. The connection and disconnection of an initiating explosive device control circuit can be controlled by plugging protection plugs or emission plugs into the star catalogue sockets, and an initiating explosivedevice detonating loop, a detonating time sequence and a bridge wire resistance value can be measured for many times at any stage.

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
