煤矿井下排水系统是煤矿安全生产的重要环节,传统的基于单片机的系统稳定性、 可靠性较差。因此,将可靠性、实时性很高的嵌入式系统应用于煤矿井下排水系统中具有极强的现实意义。该系统实现了煤矿井下排水系统的基于嵌入式系统的网络接入,采用基于ARM处理器网络接口的硬件设计,以及μC/OS-II嵌入式实时操作系统,并阐述了网络芯片应用中的几个技术问题。 关键词:煤矿;排水系统;嵌入式;网络接口;μC/OS-II Abstract:The drainage system of underground coal mine is an important part of secure production. However, traditional system based on single chip is devoid of stability and dependability. Hence, it is quite necessary that embedded system be applied to drainage system of underground coal mine. This system realized the network accessing which was based on embedded system in drainage system of underground coal mine and adopted the design of network interface based on ARM processor and μC/OS-II operating system. Moreover, several technical problems in application were resolved. Key words: Coal mine; drainage system; embedded system; network interface; μC/OS-II
