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
