【Abstract】 Process data is a rich information resource. The main purposes of process data compression are to reduce storage memory of process data, to facilitate in data processing, and to decrease the traffic in process data transmission. A general description of process data compression is given in this paper. Several algorithms of process data compression are introduced in detail, such as box car, backward slope, SDT, PLOT and vector quantization. Furthermore, several practical problems of process data compression are pointed out. This paper will be helpful for theoretical research and application of process data compression.更多还原
