Abstract:

According to the poor performance of the traditional data network resources sharing capability and data load ability, and combined with the increasing number of intelligent parts of construction machinery and the demand of data complexity, based on the high reliability of CAN and the good performance of the throughput capacity and resource sharing ability of industrial ethernet, a novel network construction was proposed herein, the basic idea was double nets shunt. Experiments demonstrate it can ensure the low packet loss,and well meet multi-unit and communication requirements needed in industrial scene.

Key words: CAN highway, Ethernet, double nets sharing, data network architecture

摘要：

针对已有工程机械设备数据网络在资源共享能力差、高负载率下丢包率高等问题，以及工程机械智能化程度日益增高、部件数量日益增多的应用需求，结合CAN总线可靠性高和工业以太网吞吐量大、资源共享能力强等优点，构建了一种用于工程机械设备数据传输的双网分流构架(DNSA)。实验证明，DNSA丢包率低，能很好地实现监控网络间的资源共享和利用。
