Fuze Logic Control Circuit Design And Algorithm Research

The Safety Logic Control Circuit of MEMS Fuze is designed in this thesis. The state is controlled by the hardware controller CPLD and the software controller ARM. The algorithm of environment information identify is analysed, which improves security and reliability of Fuze.Two environment informations acquired can be processed in two ways by hardware controller CPLD and software controlled ARM. Then the first arming control signal is the first environment information's and the second arming control signal is the second environment information's.The two arming control signal can be obtained by the CPLD and ARM processed result. The final arming control signal can be send when the two arming control signals' time sequence satisfies the request. The fuze can be armed the moment the final arming control signal is detected.This thesis first analyse Environment information and research the domestic and foreign application of microprocessor in the fuze, propose the scheme of The Safety Logic Control Circuit of MEMS Fuze which consists of the power circuit, signal conditioning circuit, AD transforming circuit, system clock circuit, control circuit based on CPLD and ARM, reset circuit, the Serial Communication Circuit. The core components of the system are composed of CPLD and ARM. The implementation of the A/D control logic, DEBUG logic, algorithm logic, communication logic to ARM is based on CPLD; Data Storage, algorithm and serial communication with PC are implemented by ARM. The feasibility and stability of system has been proved by the experiment.
