摘要
工情信息已是实现防汛抗洪决策的重要根据,是有效解决江河流域及水库洪水预报、防洪调度及水资源合理利用的先进手段,本文通过单片机以及嵌入式软硬件开发技术,并利用GPRS无线通信技术,设计并实现了对工情信息的采集和传输显示。
工情监测系统有下面几部分组成:移动终端的软硬件开发、中心服务器的软件开发以及开度的视频的及时反映。工情监测端负责将所采集到的数据和现场图片发送到中心服务器。中心站服务端接收各个测站传送过来的数据和图片,做进一步处理后储存到中心站数据库中,供移动终端随时查询。
移动终端是整个系统设计的重点,采集分两部分:采用51单片机把传感器采集的开度参数信息(数字信息)进行处理,并发送终端进行动态显示并记录数据库。采用基于S3C2410的ARM开发板和嵌入式Linux作为系统平台,采集的视频图象通过扩展串口GPRS模块来实现与中心服务器的无线数据传输,把采集的视频信息发送到中心服务器上,并写入数据库,本过程中结合了OV551的网络摄象头监测。

Abstract
The labor sentiment information already realizes the flood prevention flood-fighting decision-making important basis, was the effective addressing Pacific basin and the reservoir flood forecasting, the flood prevention dispatch and the water resources reasonable use advanced method, this article as well as inserts the type software and hardware development technology through the monolithic integrated circuit, and using the GPRS munication, designed and has realized to labor sentiment information gathering and the transmission demonstration.
Under the labor sentiment monitor system has several parts positions: The mobile termination software and hardware development, the central server software development as well as opens video frequency the prompt reflection. The labor sentiment monitor end is responsible for the data and the scene picture which will gather transmits to the central server. The central station service end receives the data and the picture which each survey station transmits, after do further processes stores up to the central station database in, inquires as necessary for the mobile termination.
The mobile termination is the overall system design key point, gathering divides two parts: Uses 51 monolithic integrated circuits together the sensor opens the parameter information (numerical information) to carry on processing, concurrently
