摘要
基于嵌入式系统方案,采用μCLinux操作系统和LPC2200系列开发板等来设计用于同时测量电路中的两路电压参数的装置。采用10位A/D转换精度,采用容量小的μCLinux内核。采用内核模块的方式加载驱动程序,使得内核精简,应用程序的运行速度更快,其整体优越性远超过以前使用的单片机系统。首先,建立系统交叉编译开发环境,编译并移植μCLinux内核和文件系统到LPC2200开发板上。然后,以内核模块的方式安装A/D设备驱动程序连接所使用的底层硬件和上层应用程序。最后编写应用程序读取两路电压参数,编译并拷贝到开发板运行。测量结果准确、实时、有效。
This paper is committed to making a device for simultaneous measurement of two-way circuit voltage parameters. Based on embedded systems, using the uCLinux operating system and LPC2200 series development boards complete the function of this device. Using 10-bit A/D conversion precision, and the system uses the small capacity of the μCLinux kernel. Moreover, the way of kernel module is used to install a A/D device, it makes the kernel more condensed and makes applications run faster. The whole superiority exceeds the original SCM. First, compiled and transplanted μCLinux kernel and file system to the LPC2200 development board.Second, install a A/D device drivers by way of kernel module to connect underlying hardwares and the upper applications. The last, write applications program to read two-way voltage parameters, compile and copy to the development board to run. Obtained measurement results are accurate, real-time, effective.
