Abstract


Based on the atmospheric polarization mode bionic navigation is to develop the key technologies of the human ability to navigate in a complex natural environment . The atmospheric polarization mode contains important compass information , the the atmospheric polarization information detection device development work on the study of great significance . In this paper, advanced embedded technology , focusing on high - performance ARM9 processor AT91RM9200 designed and implemented a way to independently complete information detection , motion control , data acquisition and information processing tasks atmospheric polarization information detection device hardware system . The main contents are as follows : (1) analysis of the function and structure of the detection device , designed as the core of embedded ARM9 processor AT91RM9200 hardware system architecture , this article explains the composition and role of the two parts hardware body and the related software systems and hardware debugging . (2) According to the the polarization information detection principle , designed a new type of polarization information detection sensor , a detailed description of the structural characteristics of the sensor and circuit design , the focus of the structural advantages of the sensor , the additive error sources and circuit compensation method . (3) elaborate atmospheric the polarization information collection and control system of the hardware module circuit design , and discusses the main circuit board (PCB) design steps and skills to achieve a field environment, stand-alone acquisition , control, processing and communication capabilities . (4) summarized the hardware system debugging process debugging problems and solutions , and gives the results of hardware systems with the entire development of the detection device . Finally, the effective detection experiments to verify the detection principle, and preliminary evidence of the effectiveness of the system .
