战术导弹控制系统BIT设计方法

Built-in-Test Design Method for a Tactical Missile Control System

摘要:

战术导弹控制系统测试是其研制、生产和交付使用阶段的重要环节，为了快速便捷地完成对控制系统功能性能指标测试，及时检测和隔离故障，保证导弹安全、准时发射，根据新一代导弹控制系统设计特点，重点针对导弹交付后使用阶段测试需求，提出一种分布式与集中式相结合的机内测试（BIT）方案，详细给出了单机分布式BIT和系统集中式BIT的设计方法，该方法在无外部设备辅助测试的条件下可覆盖控制系统所有硬件资源，实现控制系统工作状态和工作性能的快速评估，为导弹或运载火箭控制系统测试性设计提供参考。

Abstract:

Control system testing is a key link of design, production and usage of tactical missile . In order to quickly obtain the performance indicator of control system and detect faulty equipment, a method of new hybrid built in test (BIT) based on distributed-centralized architecture is proposed. A typical hybrid BIT design scheme which combines hardware and testing methods is provided. This scheme was mainly applied in force using stage. The test can verify and cover all the hardware of control system without the additional equipment. The design method proposed in this paper can be used to improve the testability of missile weapons and launch vehicle.
