Control System Based On Embedded Technology Equipment

In this dissertation, an Embedded Application System based on ARM920T (AT91RM9200) is applied in instrument contol, which include hardware and software. This system is developed based on high performance, low cost and many controllers inside of the embedded processor, and enlarged GPIO for the plat of the hardware and, software.This system is already applied in radar test instrument which designed by SINE LTD. It can work under military temperature. It's composed of EL-LCD and non-coding key board to be the man-machine interface, GPIB interface to work in conjunction with other test instrument, the minimum system which base on at91rm9200 to be the master control kernel. The system Work with the other internal model, like the frequency synthesizer, the decay model and frequency measuring model, to generate the 5cm microwave signal, measure the frequencies of 5cm and 10cm microwave, and provide man-machine interface in Chinese. Also, some parameters which need to keep secret is processed.This master control kernel is base on the embedded processor AT91RM9200-CI, ATMEL, which support to operate in military temperature. The software platform is an open source RTOS,μC/OS-Ⅱ. In the dissertation, the demand of the control system is analyzed according to the customized function. The scheme planning is described detailed. In the dissertation, the master control module and the interface circuit of sub-module is described as the hardware part. The transplant ofμC/OS-Ⅱand communication protocol between the control module and sub-module is described as the software port. In the end, the dubuging process and touchstone is introduced in detail.
