摘要
为提升导引系统的路径搜索效率,研究贝叶斯算法在导引功能中的推理过程,采用嵌入式方案,基于REAL210开发板和STM32F407处理器对导引系统的硬件进行了设计,并针对系统的初始化、中断等控制流程进行了软件设计。导引系统采用超声波测距方式,通过四阶带通滤波电路提升了抗干扰能力。
In order to improve the path search effi ciency of guidance system, the Bayesian network learning and reasoning process is analyzed. With the embedded scheme, the hardware is designed based on REAL210 plate and STM32F407 processor, and the software is designed according to the process of system initialization, interrupt control. Ultrasonic ranging method is used in the system, and the antiinterference ability is improved through the fourthorder bandpass fi lter circuit.
