文中介绍了一种用于地下管井的远程终端监控系统。该系统是以ARM9为核心的AT91RM9200微处理器作CPU,通过A/D模块和Hart模块进行数据采集,经过处理后由GPRS模块发送至监控中心的系统。该系统的软件在Linux操作系统的虚拟机同ARM平台的交叉编译环境下编译实现,具有很好的稳定性和较低的功耗。文中从系统的整体设计,硬件设计,软件设计等方面介绍了该系统。
This paper introduces a remote terminal monitoring system for underground tube wells. The system is based on ARM9 AT91RM9200 microprocessor as CPU, through the A / D module and Hart module for data acquisition, after processing by the GPRS module sent to the monitoring center system. The software of this system is compiled and realized under the cross compilation environment of Linux operating system virtual machine and ARM platform, with good stability and low power consumption. This article introduces the system from the overall system design, hardware design, software design and so on.
