【正文】 ect. the whole system has the features of high reliability and strong expand ability． the main topic of this paper is the design of TCP/IP munication module which is being introduced around each independent module of coal mine data collection substation. the power and reset module. CAN munication module. LCD display module. rework and storage for parameter module are introduced as well. On the foundation of the hardware design, the software design based on operation system μC/OSⅡ is processed. The software design contains two parts. One is hardware driver program, another is system task. Driver program contains the realization process of each module. and the realization process of TCP/IP munication is mainly introduced. According to the practical function of each module of the substation, the PRI of tasks is assigned and the design flows of coalmine data collection substation’s tasks are introduced in the system task part． III KEYWORDS: munication substation， ARM， μC/OSⅡ ,TCP/IP I 目錄 摘要 (中文 ) ..................................................................................................................................
