Bore Environmental Information Collection System Design And Its Recognition Algorithm

The safety and arming system is one of the important parts of the fuze, and is the key of the whole arm to go into the most effect .A environment information gather and process system is designed based on the theories of the fuze environments identify .in this thesis .The purpose of the design is to identify the launch environment, solve the difficult problem of the miniaturization and coherence of the fuze. It wants to be used in the safety and arming system of the fuze to insure the security and reliability of the fuze.The theories of the ballistic environment information identify is researched in thesis. Then some kinds of means of the environments identify are introduced, and the best way used in the system—threshold-time-gate, is chose through analysis. MEMS high g value sensor is also introduced in thesis ,and the suitable sensors are chose according to the request of the safety and arming system of the fuze ,which have been tested .Then sensitivity.of these sensors is demarcated. Based on MSP430F449 one-chip computer, combined with the MEMS sensor and the arithmetic of environment information identify, environment information and process system is designed, and the feasibility of gathering acceleration twice and the arithmetic are validated by simulation.
