摘要
为了实现同一套环境监测系统能应用于不同的污染源,使环境监测更方便、快捷,提出一种远程环境监测系统设计方案,该方案采用嵌入式系统和无线远程通信技术相结合的设计思想。与传统环境监测系统相比,该系统设计是以ARM7系列单片机LPC2214为核心,采用模块化设计,可接入多种传感器,通过μC/OS-Ⅱ调度和管理任务,实现环境参数数据的采集与处理,并经过DTU无线模块把数据发送至上位机,由上位机接收、存储并显示各个参数指标,从而实现了使用同一套环境监测系统,可同时实时监测与远程控制多个污染源。
In order to achieve the same environmental monitoring system in different pollution sources, and make the environmental monitoring more convenient and faster, this paper proposed a remote environmental monitoring system design, which used embedded systems and wireless remote communication technology. Compared with the traditional environmental monitoring system, the system design uses LPC2214 ARM7 MCU as core and modular design, can access a variety of sensors. The system design achieves environmental parameter data acquisition and processing through μC/OS-Ⅱ scheduling and management tasks, and then through the DTU wireless module, sends data to host computer, and host computer receives, storages and displays the various parameter indicators. The system design achieves the real-time monitor and remote control at the same time to many environment monitoring substations using a same environmental monitoring system.
