摘要:为了实现水质污染情况的远程监控,在以嵌入式微处理器S3C2440为核心的硬件平台上,进行了Qtopia库的移植,并利用Qtopia技术开发了远程污水数据终端专用软件。远程污水数据终端专用软件通过RS485总线与采集仪器连接,获取当前污水化学含氧量(COD)值和流量值,并进行了数据的分析和显示,同时通过SIM300E模块接入通用分组无线业务(GPRS)网络,并与中心监控程序建立了网络连接,实现了污水COD值和流量值的显示和远程传输。试验结果表明,该嵌入式远程污水数据终端对污水状态数据的传输快速、准确。

Abstract: Aiming at realizing the remote monitoring of water pollution, the Qtopia library was transplanted to the hardware platform which has an embedded microprocessor S3C2440 core. And using Qtopia technology, a dedicated software of remote sewage data terminal was developed. Through the dedicated software of remote sewage data terminal, the RS485 bus was connected with the acquisition instruments, the current value of the chemical oxygen demand (COD) and the flow was gotten, at the same time through the SIM300E module access to general packet radio service (GPRS) network, and a network connection with the center monitoring program was established. The display and remote transmission of the current value of the COD and the flow were realized. The test results indicate that the system transports the sewage state data rapidly and accuratly.
Key words: wastewater monitoring; general packet radio service (GPRS); Qtopia; embedded system; chemical oxygen demand(COD)
