Reliability Design and Research of Launching Control Device on Catapulting

摘要:

主要从信号的输入,传输以及火工品方面考虑发控装置的可靠性;设计了有效的信号消抖方式和稳定的422通信链路,确保了发控信号的可靠输入;针对火工品点火,设计了安全可靠的点火控制电路,并加入了火工品保护、点火时序条件等防护和保障措施;该弹射发控装置能提供50ms以上约10A的火工品点火电流,目前已成功在某弹射靶场试验中使用,具有较高的安全可靠性和应用价值。

Abstract:

The reliability of launching control device was mainly considered from the input and transmission of signal, designs on pyrotechnics. It designs an effective way to disappear shakes of signal, a stable 422 communication circuit, ensured the reliable input of control signal. For pyrotechnics ignition, it designs a safe and reliable ignition control circuit, and joined pyrotechnics protection, ignition timing and other protective safeguards. This launching control device can provide pyrotechnic ignition current about 10A, more than 50ms. Now the device has been successfully used in a catapulting range test, having high safety and reliability and application value. 
