Study And Realization Of CAN-Ethernet Gateway Based On ARM7

With the combination of measurement, control technology and Internettechnology, The measurement and control technology must follow the trend ofInternet, which promotes the rapid growth of embedded network technology. Thedissertation analyses the whole data communication technology between CAN Buswith Ethernet and gives the realization plan between them by using the advancedARM7 embedded processor with rapid speed, high performance. By splitting andrecombining the frame this gateway scheme accomplish the frame conversionbetween the two networks and realizes the interconnection communication ofcomputer network based TCP/IP protocol with CAN bus field control networkbased CAN protocol ultimately.The dissertation revolves the design and the realization of CANbus-Ethernet gateway equipment. Here it concentrates on following some majorparts:1. The system structure designing of the interconnection2. Designing and realization of embed-TCP/IP protocol stack3 The hardcore protocol exchange model designing in this system4. The interconnection system application software designing andrealization5. CAN bus-Ethernet gateway software programming, debugging and test. Thetest result has confirmed this design accuracy.
