彩信图像监测技术在河道冰-水情远程无人监测中的应用

针对黄河中上游冰凌灾害预报系统的建设,设计研制了黄河河道冰、水情图像远程无人自动监测系统.该系统基于GPRS移动通信中彩信图像数据传输技术,利用单片机控制摄像探头采集和压缩黄河河道现场冰情图像信息,通过GPRS网络以彩信格式发送到用户手机,实现了对黄河河道冰情图像的无线远程实时监测.该系统可以使冰情检测人员在移动过程中随时获取河道实时冰情图像信息,更加适合野外环境下冰凌灾害预防的监测与预报,具有较大的工程应用价值.

The Application of MMS Image Monitoning Technology in the Field of Remote Mnmanned Monitoring Ice-water Condition of River

Based on the new research results in the detection of ice-water obtained by the Institute of Measurement and Control Technology in Taiyuan University of Technology,remote automatic monitoring system for the ice-water of the Yellow river was developed according to the field test according to the the construction of the ice disaster prediction system for the upper reaches in the Yellow River.For the limitations of the the special environment of the channel,the mobile communication technology GPRS was used in research of the system to get the remote real-time image of the ice in the Yellow River ice flood season.By using the single chip computer technology,the GPRS wireless communication module with MMS agreement and the image acquisition and image compression function modules,the single-chip computer can control the serial camera to achieve the image processing and image compression and then the collecting image will be sented to the mobile phone user through the MMS forma, in order to realize the wireless remote monitoring of the ice thickness and ice image.Selecting the appropriate monitoring points is to achieve the remote monitoring to get the information of river regime,which can achieve the automatic monitoring and and emergency monitoring of the forming process of the Yellow River ice.The system has the advantages of regular monitoring,stable performance and low power consumption.
