Dual Environmental Information Collection System Design And The Recognition Algorithm

Based on the study of the environment identify theory of the fuze safety system in the thesis, dual environment informations gathering and processing system based on MSP430F449 Single Chip Microcomputer is mainly designed. It consists of four parts, including the theory of environment information identify, the designing of the system circuit, the designing ofprogramm software and system test.At first the fuze safety system and its development are introduced in the thesis. The fuze environment information and the theory of fuze environment information identify are discussed through analyzing some kinds of means of the environment identify. The method of threshold value—time—gate and comparisom mothod are used in the environment information gathering and processing system.Then, according to the theory of the environment information identify, the software and hardware of the system in dual environment informations gathering and processing are designed, which based on MSP430F449 Single Chip Microcomputer. The acquisition, transmission and process of the acceleration and geomagnetism signal are realized based on the rich resources(FLASH, ADC, USART module, etc.)of the MSP430F449 Single Chip Microcomputer. At the same time, the miniaturization, low power consumption and anti-jamming capacity of the system are considered.Finally, the software, hardware and static state property of the system are tested. The test indicates that the system reachs the anticipated requirement.
