摘　　要：为实现不同设备接口不同通信协议的数据融合和系统的网络化监控及管理,提出了一种分布式高速多总线通信系统的软硬件设计方法。软件采用"查询-响应"模式,高速总线节点根据接收到的数据包中节点代码执行不同的功能且返回不同的值,实现对不同设备的控制和管理。实验结果表明,该系统具有较强的通用性,可实现RS-232、RS-485、USB等通信协议的转换,且传输速率高达10 Mbit/s。In order to achieve data fusion in different device interface with different communication protocols and system network monitoring and management, a design method of distributed high-speed multi-bus communication system is proposed. ＂Query -response＂ mode is used to complete control and management on different devices in the software design, which means that the bus node performs different functions based on the node code in the received packet and then returns different values. Experiment results show that this system can realize the conversion between RS-232, RS- 485 and USB. The data transfer rate is up to 10 Mbit/s.
