The Research Of Industrial Embedded Control Platform Based On UC/OS-Ⅱ

Embedded system is a comprehensive technique course, which is the combination of computer technique, the semi-conductor technique and the electronics technique and all kind of applied realizations. In the thesis, it is discussed comprehensively that the designing process on the embedded industrial control platform based on uC/OS-II and ARM9 embedded processor. As one kind of verification of this embedded industrial control platform, this paper accomplished a long-distance Data Acquisition Terminal.The paper presented the basic framework of the platform based on ARM9 embedded microprocessor and real-time operating system uC/OS-II, it mainly completed the following work:(1) The operating system replanting and modification. Firstly, this text replanted the real-time operating system uC/OS-II on S3C2410 which was a Samsung ARM920 chip. Then it modified the operating system's data structure,task ready list and interrelated functions, made it stand by the same priority scheduling, brought forward the project about how to resolve the problem of the priority reversion. Added the usable task's number to 256 and meet the industrial control's need in the future. In the end, it completed the design of double kernel under the time-sharing and real time scheduling.(2) The research of the embedded system's periphery components. According to the system's hardware unit and the operating system uC/OS-II, it brought forward the project of how to realize the embedded component. The whole component modules includes some typical modules in industrial control such as the LED video module, memory module, serial communication module, LCD module and touch screen interface module and some other peripheral equipment.(3) The design of the file system based on FAT16. Refer to the FAT16 file system, with the industrial control system's terminal, this paper designed FAT8 file system based on the operating system uC/OS-II and the embedded flash storage media, it realized the modification of the kernel and the transfer of basal API.(4) Combining the operating system uC/OS-II with the TCP/IP module, the paper realized the network function and replanted the TCP/IP protocol stack LWIP on...
