摘　　要：惯性平台是导弹、航空飞机、运载火箭等飞行器中制导与控制系统中的核心部件,一旦出现平台失稳倒台、加速度计飞转,将会对惯性平台造成无法挽回的重大损失,是一种致命性的故障。本文介绍了惯性平台失稳倒台、陀螺摆式加速度计飞转的基本原理,由于可编程门阵列FPGA具有集成度高、处理能力强、运行速度快、灵活可重配置、实验风险小等优点,故将FPGA引入到保护电路设计中去。设计了基于FPGA防倒台、防飞转平台测试保护电路,给出了具体的设计过程,实验验证了保护电路的有效性。The inertial platform was the core component of missiles,aviation aircraft,launch vehicles＇ guidance and control systems.It＇s a fatal malfunction when the collapse of an inertial platform and accelerometer turning to fly were appeared,which would result in irreparable significant loss for the inertial platform.In this paper,the basic theory about the collapse of an inertial platform was depicted.The principle of a pendulous gyro accelerometer turning to fly was expatiated.FPGA was introduced into the design of the protection circuit because of FPGA with highly integrated,strong processing ability,runing fast,flexible reconfigurable and little experimental risk,etc.A protective circuit based on FPGA about preventing the collapse of the inertial platform and accelerometer turning to fly was designed,and the hardware circuit design process was given in detail.Experiments showed the validity of the circuit.
