    J. Electromagnetic Analysis & Applications, 2009, 1: 245-248 245 doi:10.4236/jemaa.2009.14037 Published Online December 2009 (http://www.SciRP.org/journal/jemaa) Monitor System for Protection Device Based on Embedded RTOS Yang WANG, Xianggen YIN, Zhe ZHANG Electric Power Security and High Efficiency Lab, Huazhong University of Science and Technology, Wuhan, China. Email: [email protected] Received September 8th, 2009; revised September 26th, 2009; accepted September 29th, 2009. ABSTRACT For the purpose of the monitor system in digital protection, the embedded real-time operating system (RTOS) and the embedded GUI (Graphical User Interface) is introduced to design the monitor system. Combining the necessity and the application value of the operation system, the choice of embedded Linux and Qt/Embedded is completely viable for the monitor system in digital protection for generator-transformer sets. The design with embedded Linux and embedded GUI enriches system information, increases developing efficiency and improve the generality. Keywords: Real-Time, Operating System, Embedded Linux, Protection, Monitor System 1. Introduction gineering at present. Restricted by factors like cost, en- ergy consumption and chip size, embedded systems are After the development of digital protection for over 20 closely linked with their application and market. It is years in our country, The rapid development of DSP critical to design and develop embedded system products (Digital Signal Processor) and high performance embed- with the proper cost, function and performance. ded microprocessor not only make the digital protection Embedded system is used in power system for a long function more perfect and reliable, but also can gather time, including data collection, automatic equipment, and deal with more abundant data [1,2].
