摘要
为了实现电爆管火工品的高安全高可靠引爆,设计了一套高安全航空电爆管驱动及控制系统,包括传感器接口、硬件接口、软件接口和数据接口。硬件接口采用基于反时限保护的功率输出,实现功率电路的自恢复和高安全输出。软件接口采用分级接口的故障检测方式,实现电爆管断线、输出异常等故障诊断和隔离。数据接口采用指令有效性确认,实现指令、状态和BIT数据的综合处理。实验结果表明,电爆管驱动和控制电路安全可靠,对提升飞机系统安全具备重要意义。
In order to achieve high safety and reliability in the initiation of squibs,this paper designs a high safety aviation squib drive and control system,which mainly includes sensor interfaces,hardware interfaces,software interfaces,and data interfaces.The hardware interface adopts a power output drive method based on inverse time protection to achieve self recovery and high safety output.The software interface adopts a hierarchical interface fault detection method to identify faults such as electric detonator breakage,positive and negative terminal output abnormality,achieving accurate isolation and rapid positioning of faults.The data interface uses instruction validity validation to achieve comprehensive processing of instruction data,status data,and BIT data.The experimental results show that the drive and control system has high safety and reliability,which has important practical significance for improving the safety of aircraft systems.
