Abstract


Purpose to improve the hit accuracy or increase the range in order to achieve the implementation of the control of the missile body , real-time measurement of the missile body posture parameters , which is particularly important roll attitude parameters detection . For low-speed rotation of the guided shells , high muzzle velocity of the emission process , high overload , small size and other environmental conditions makes some attitude measurement system is difficult to be applied directly . This study geomagnetic induction coil combination of micro- mechanical gyroscopes detect Roll Attitude . First missile attitude measurement method , comparing a combination of measurements and the advantages and disadvantages of the commonly used methods . Geomagnetic induction coil in the installation of the bomb body derived algorithm the geomagnetic solver missile body roll attitude , determined orthogonal two-axis geomagnetic induction coil detection scheme , elaborated micromechanical gyroscope measures roll attitude the working principle of the the geomagnetic signal detection and identification , a specific roll attitude combined detection scheme . Designed in the design of hardware and software , based on TI's TMS320F2812 DSP minimum system the geomagnetic measurement unit , the micromechanical gyroscope measurement unit , power supply module , communication module , A / D acquisition , serial communication through the JTAG interface debugging functions , the development of embedded systems software , and roll attitude detection scheme , and to take the appropriate hardware and software anti-jamming measures , so as to improve the accuracy . Finally , the entire system is manual turntable experiments and wind tunnel experiments to verify the feasibility of the roll attitude detection devices .
