Abstract:A kind of design and application for current and voltage transmitter based on CAN bus was introduced. The overall architecture of the transmitter was presented. Measurement principle of voltage and current was described, and to the transmitter, its hardware constitutes and software implement were narrated in detail. Upper computer communicates with transmitters by PCI5121 intelligent interface. It was indicated through experiment that the system is simple, reliable and cheap for its function. It should have a good application in the future.
Keywords:voltage/current transmitter  fieldbus  CAN bus  intelligent node
