| Abstract: | In order to meet the requirements of whole ship network technology and satisfy the communication demand between fieldbus and Ethernet as well as other type bus, double-redundant hyterotypic network bridge specific for CAN fieldbus and Ethernet is developed, which can improve the reliability of communication. ADμC812 PLC compatible with 8051 is taken as CPU, which is cooperated with SJA1000 CAN fieldbus controller and RTL8019 Ethernet controller. Test results show that this device, featuring with redundant capability, can realize the communication among nodes in the fieldbus and transmit fieldbus signal to Ethernet. |
