Data splitting and compounding technology for a data real-time transmission system
Li Maotang, Yonglin Xue, Jang Jingshan, Mingfeng Li · 2002
A very useful airborne-ground disaster surveying system (AGDSS) is being developed. The sensors of the surveying system consisted of a GPS receiver and some remote sensing instruments. The processed and compressed data are transmitted to ground receiving stations directly. The AGDSS includes an optical sensor that is of large swath width, high resolution and produces a huge quantity of data. So it is very difficult to assemble the sensors, sample, compress and deal with the output data of the sensors in real-time. However, data splitting and compounding technology has been developed and it can solve the thorny problem. The distinguish feature of the data splitting and compounding technology is the multi-CPU parallel working method adopted. There are some advantages for the data splitting and compounding technology, so it is important to the real-time transmission system for huge amounts of data.
