摘要
介绍了一种基于CAN总线技术在电流、电压变送器中的设计和应用。给出了变送器的整体结构,阐述了电流、电压的测量原理,论述了变送器的硬件组成和软件实现方法,上位机采用PCI5121适配卡与变送器进行通信。实验表明,该系统具有结构简单、可靠性高、性价比高等特点,有广阔的应用前景。
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.
