摘要:

在嵌入式操作系统VxWorks中,直接使用WindML设计人机界面是一件耗时耗力且非常困难的事情,更不用说设计出带有动画效果的人机界面了。第三方界面设计软件Tilcon的出现改善了这种状况,使用它可以开发出内容丰富且漂亮的人机界面。通过对Tilcon的结构、特点的简要描述,结合实际开发的动画实例,给出了使用Tilcon进行动画设计的具体实现,并对实现过程中所涉及到的技术细节进行了探讨和详细说明。以实际工作程序中的部分重点函数说明了使用Tilcon进行动画设计的简单方便性。

A software design of communication server based on embedded RTOS(Real- Time Operating System) VxWorks is proposed to satisfy requirements of electric power dispatch automation system for high reliability and real- time performance. The hardware is designed based on embedded microprocessor ATglRM9200,and the software realizes protocol conversion and data transfer. The software system adopts double- layer client/server structure. To downstream channels,the communication server acts as a client,requesting data of protection units and supporting protocol IEC- 60870- 103. To upstream channel,the communication server acts as a server,responding the data request of dispatch master station and supporting protocol CDT(Cyclic Digital Transmission), IEC - 60870 - 101 and IEC - 60870 - 104. The software architecture consists of models of system initialization,system confignration,data request and processing of downstream channels,data processing of upstream channel and database management. The data stream and the muhitask division of communication server based on H.GEMMA rule are analyzed. Task priority is determined and it can be changed by calling taskPrioritySet function. The communication server uses semaphore and message queue as communication modes to guarantee the real-time performance of system. The main program flow of communication server is given.
