| Embedded graphical user interface is the communication interface between embedded devices and users, because it has a good man computer interaction, so it has been widely used in the embedded software system. With the development of embedded devices in people’s daily life more and more widely used, people’s requirements for high performance embedded graphical user interface is more and more urgent. Substation communication controller is a typical embedded system, it requires that the number of remote communication, telemetry, protection of automatic device information, and maintenance personnel through interaction, realize the normal operation of power system. Therefore, the substation controller, developed a set of intuitive and easy to control automatically control the interactive system, has important significance to improve the level of automation of substation.This paper first analyzes the embedded operating system and its graphical user interface (GUI) development status of technology, and analyzes the advantages and disadvantages of several embedded GUI system under the Linux. Through to the transformer substation communication controller GUI system needs analysis, to identify and design of S3C2410 based on the microprocessor chip ARM, using the Qt/Embedded platform for the development of the overall scheme of substation automatic control interaction system. Through the analysis of system structure and operation mechanism of Qt/Embedded, to achieve the establishment of transplantation and the transplantation of BootLoader file system, embedded Linux, completed the communication and graphic user interface of substation communication controller design work, the test results show that, the system realized the substation information, information query, interactive communication system the system configuration and communication functions, meet the design requirements of substation communication controller.The embedded interactive system implemented in this paper can not only meet the application requirements of substation automatic control, and can be carried out on the basis of the remote monitoring function expansion, laying the foundation for the subsequent substation intelligent unmanned development demand. |
