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.
