The Design And Research Of A Embedded Communication Management Device

Along with the progress of the embedded technology more sophisticated, more and more intelligent control equipment penetrates into all walks of life and people's life. The application of the embedded technology greatly improves the management performance of hydropower station automation computer monitoring system and offers the high stability, low cost solutions. This paper studies the actual application requirements of communication between the hydropower computer monitoring system with the field of intelligent control equipment and distant scheduling, designs the embedded communication management device realized the related requirements.Firstly, this paper discusses the situation at home and abroad of the development of power system communication, expounds the significance of the development of embedded communication management device, analyzes the function of the device be provided according to the scene of the hydropower. Then, according to the deficiencies existed in the related field studies, upgrades the software and hardware of the first generation communication management machine and gives the construction scheme of embedded communication management device based on Intel XScale kernel processor the reduced instruction set (RISC) and embedded Linux operating system as the platform. In subsequent chapters, hardware part introduces the selection of function modules of the chip and the measures of improving system performance, and makes a detailed analysis and explanation of the circuit principle of each module. Software platform part introduces the characteristics of embedded Linux system and independent construction of the platform. Software part detailed introduces the realization of special ladder diagram, communication protocols and script compiler, and finally achieves cross-platform software applications of communication management device using ladder diagram accord with international standard as development language.
