摘要
为了解决煤矿监控网络与第三方设备兼容性差的问题,文章提出了一种嵌入式多总线通信协议转换器的设计方案,重点阐述了该方案软件部分的内容——μC/OS-Ⅱ实时操作系统在AT91M40800上的移植实现,指出了移植过程中应注意的问题及解决方法,并编写了测试代码。该软件已经移植在自行开发的电路板上,多任务运行效果表明,系统运行稳定、可靠。
In order to solve the problem of bad compatibility between monitoring and control network of coal mine and the third party equipments, the paper proposed a design scheme of embedded multi-bus communication protocol converter. It expounded contents of software part of the scheme emphatically, namely implementation of porting μC/OS-Ⅱ real-time operating system to AT91M40800, and pointed out the problems that should be paid attention to in the porting process as well as solution methods. At last it programmed testing codes. The software had been ported in the circuit board developed by our research group, the running application showed that the system is steady and reliable under multi-task environment.
