摘要
分布式监测系统长时间的连续监测,累计的数据量非常可观,为了数据实时传输及节省传输成本,对监测的数据现场预处理,采取一定的方法压缩数据量非常必要。目前,针对状态数据传输过程中的数据压缩与传输效率的研究还很少,一般采用黑匣子功能模型或白匣子功能模型,虽然具有减少数据冗余的作用,但是没有考虑数据流本身冗余特性,提出基于数据压缩的分布式监测系统功能模型,提高了通信速度和可靠性,满足了实时传输的要求。
A mass of monitoring condition data is produced in distrubuted monitoring system for a long time.It is necessary that the data is compressed in some methods to transmit continuously and economize for data input stream before transmission.Presently,the investigation of data compression and transmitting efficiency in course of transmission is little.Although the manner of black-box function model and white-box function model perform a funcition for reducing the data redundancy,the redundancy of data stream by oneself don＇t been considerd.The function model of distributed monitoring system based on data compression is put forward in the article that improve the communicating speed and reliability,satisfying the transmitting require of real-time.
