【摘要】 本文以采用集中监控、分散控制多电机方案的国防某实验基地弹目空间交会模拟平台控制系统为基础,运用嵌入式系统方案设计了其主控制器,并通过设计的ZigBee无线协调器加入无线网络,最终实现了集中监控的功能要求。文章首先对弹目交会系统现状进行了研究,深入分析了运动控制系统相关技术和嵌入式系统发展现状。根据对总体方案的研究和主控制系统功能要求,提出了基于ARM的嵌入式Linux系统的主控制系统方案。然后分别设计了嵌入式主控制器和基于CC2430芯片的ZigBee无线协调器的硬件系统。接着,在硬件系统的基础上完成了嵌入式Linux系统的构建,其中包括Bootloader与Linux内核的定制和移植、LCD等设备驱动程序的设计和文件系统的建立。同时根据ZigBee无线网络协调器在整个系统中的功能特点,设计了基于Z-Stack协议栈的ZigBee无线网络协调器的软件系统,实现了ZigBee无线网络的协调功能以及与主控制器的通信接口。然后通过分析弹目空间交会模拟系统的特点,建立了弹目运动数学模型,并采用嵌入式图形用户界面开发工具Qt/Embedded完成了系统监控软件的设计。最后,通过对监控软件和ZigBee无线通信进行实验测试,检验了主控制系统方案的可行性,验证了监控软件和ZigBee通信的可靠性,证明系统达到了期望的功能要求。更多还原

【Abstract】 Based on Motion Control Scheme of Missile-Target Space Encounter Simulation System, the master controller of the system is designed by adopting embedded system. A ZigBee coordinator is applied to wireless network, both of which help meet the functioning requirements of centralized monitoring.At the beginning, a research on current situation of the Missile-Target Encounter experiment system and a thorough analysis of the present development of embedded system and technologies related with motion control system have been carried out. According to researches on general scheme and functioning requirements of master controller, the scheme of the master controller by using an embedded system of Linux based on Arm has been brought forward. Then the hardware system of master controller and Zigbee coordinator based on CC2430 is designed.During the following part, an embedded Linux system has been established which includes transplant and customization of Bootloader and Linux kernel, design of device driver such as LCD, construction of file system. Meanwhile, the coordinator’s software system according to functional characteristics of the ZigBee coordinator has been developed which realizes wireless communication between the master and motor controller. Afterwards based on mathematical model of Missile-Target motion, the monitoring application program has been developed by adopting Qt/Embedded.Finally, the feasibility of master controller as well as the reliability of monitoring software and ZigBee communication has been tested. The results prove that the system meets the expected functioning requirements.更多还原
