刨煤机组CAN网络数据缩减技术研究

Research on Data-Reduction Strategy for Automatic Plough Group CAN Network

针对刨煤机组CAN网络数据日渐增多而CAN带宽资源有限的问题,引入用于减少网络传输数据的数据压缩算法,提出了基于标识符的数据压缩方法MDR,介绍了MDR算法的数据压缩与解压缩原理,压缩算法可以显著降低总线负载,改善信息的实时性。

As functionality of automatic plough group （APG） increases in complexity, the data on the CAN network increases as well. Maximum bus utilization often becomes the communication bottleneck. To solve these problems, a mended data reduction （MDR） algorithm to reduce the amount of data to be transferred on CAN bus is introduced. The principle of data encoding and decoding algorithm is given, this new algorithm method will enhance message latency and bus utilization.
