摘　　要：详细介绍了一种多通信接口的M_bus数据集中器的硬件设计。使用嵌入式主控芯片LPC2387,实现了数据集中和处理,集成在系统中的Profibus总线接口、RS232异步串行口、CAN总线接口、以太网接口使得数据可以在多种总线上进行传输。测试结果表明,该系统的通用性强,稳定性好,数据传输的可靠性高。The hardware design of a data concentrator of multi-communication interfaces based on M_BUS is introduced in detail. Collecting and processing of data is implemented using of LPC2387. The interface of Profibus, the RS232 asynchronous serial ports, the interface of CAN bus and the interface of Ethemet integrated in the system allow data to be transmitted in a variety of bus. The practice indicates the system with the characteristics of multiple versatility,good stability and high reliability of data transmission.
