基于嵌入式Linux的移动图像监测定位仪

在环境监测中,为了获得监测位置信息的同时还采集现场真实图像信息,研制了移动图像监测定位仪。采用图像解码和数字图像压缩、全球定位系统接收机,运用通用分组无线业务移动网络将获得的监测图像和定位信息通过因特网传输给远程接收中心的服务器。仪器采用了MCF5272微理器和μC linux,并使用加密编码保证检测图像和定位信息的安全性。接收中心服务器端将获得的图像和定位信息解密并储存显示。将制作的仪器样机进行实验,在现场实验条件下,该仪器能够达到在接收服务器上获得监测图像的间隔为8~10 s。实验结果表明:研制基于通用分组无线业务移动网络的图像化定位监测仪器切实可行。

Mobile image-positioning instrument Based on embedded linux

In order to sample real images of monitoring target with obtaining the global positioning information(GPS) in environment monitor,the mobile image-positioning instrument is developed.Using images encoded and digital signals compressed,GPS system receiver,the information is transmitted to the center server that is linked to Internet through general packet radio service mobile network.The MCF5272 microprocessor and μClinux operation system are used in the instrument.The cryptogram is used as safety manner of the images and GPS information.It is decrypted,saved and shown in the server when the images and positioning information are received.The sample instrument is made.The gap for remote server to receive images is 8~10 s at present experimental condition.The result shows that the instrument based on general packet radio service mobile network is feasible to obtain positioning and images.
