应用GPS/GSM对洲滩观测和同步监控的研究

目的利用全球定位系统(GPS)和全球无线移动通讯技术(GSM)相结合的方法,对洲滩进行精确定位、测量其面积,并实现同步报告、实时监控。方法在鄱阳湖区内选择一个退田还湖地区(无螺区),一块赣江边的洲滩(有螺区),利用手持GPS设备在现场进行航点、航迹的采集,将定位数据包以短消息的形式发回GPS监控服务中心内的GPS服务器,在控制中心数据库的支持下,实时检索短消息服务,并将检索到的以短消息形式存在的定位数据包转发给控制服务中心。控制服务中心解释获得的定位数据包中的信息,在强大的GIS地图上显示被监控终端设备的位置,实现实时监测。结果手持GPS设备可以对现场行走的路线进行准确定位(自动保存为“航迹”),同时可以手动采集每个航点的经纬度。控制中心能够及时接收到GPS发回的短信息,在强大的GIS地图上显示被监控终端设备的每一个精确地理位置,实现了实时监控。结论通过GPS和GSM两种系统的有效结合,实现了通过短信方式进行位置信息传递与收集。中心控制系统同时接收终端信息,实现全面监控。将该系统应用于血防工作,不但能够及时将血吸虫病疫情发生的地点迅速上报给上级组织,而且能够通过该型GPS具备的移动通话功能指导现场采取处理措施。该系统将为血吸虫病防治工作创造一种具有技术含量高、预报速度快

STUDY ON THE INTEGRATING GPS/GSM TECHNOLOGIES FOR MEASURING AND SUPERVISING MARSHLAND SIMULTANEOUSLY

Objective Integrating the GPS/GSM not only recorded the geographic position of the marshland and measured the area,but also reported to the operations center and supervised the spots simultaneously. Methods Choosing a spot which was returned of agriculture to land(no snails), and another spot which was a marshland along the Kan River(snail habitats). The GPS was used to record the information of each dot position and the route which was transported to the operations center in short message by the GSM. The operations center received the messages and displayed them in the screen with the digital map(GIS). Accordingly, the operations center could grasp the information of the spot in time and supervise the work of the investigators . Results GPS could record and save the route which the investigators walked in the spot, the longitude and latitude of each dot position could be collected consciously at the same time. The operations center received the short message and displayed each exact position of the supervised terminal in the screen. Conclusion Integration of the GPS and GSM technologies can exchange the position information by the short message. Operations center can receive the data at the same time and carry out the real-time tracking. Application of the kind of GPS in the schistosomiasis control is convenient for reporting the emergency .With its mobile communication, the operations center can command investigators to execute some measures. The integration will offer a new supervising method which is high-tech, fast and accurate for schistosomiasis.
