摘　　要：设计研究了一种采用嵌入式Linux操作系统和PC/104嵌入式控制PC构建的通信管理装置。该装置具有8个独立的标准串行接口,1个CAN现场总线接口和1个以太网接口,可以灵活应用于计算机监控系统中的各个通信环节,实现异种网络间的通信协议转换和数据管理功能。针对不同子设备的通信规约需要进行二次开发的不足,该装置采用符合国际标准的梯形图作为开发语言,采用编译及解释执行的手段,最终实现为真正意义上的面向用户的通信管理装置。The design process of a communication management device adopting embedded Linux operating system and PC/104 embedded control PC is introduced.This device consisting of eight independent standard serial interfaces,one CAN field bus interface and an Ethernet interface,can be used in all communication links of computer monitoring system,realizes the communication protocol conversion and data management functions in different kinds of networks.Considering communication protocols of different sub-equipments need secondary development,the device uses the ladder diagram in line with international standards as the development language,takes compiler and explanation as means of implementation,and finally achieves the true sense of the direct use-oriented communication management device.
