中文摘要：

嵌入式系统的设计内部采用CAN总线通信，与外界通信则通过网络连接的体系结构，这种通信机制提高了系统的可靠性与灵活性．将此体系结构应用于基于分布的微生物总量检测系统中，取得了较好成效，具有广阔的应用前景．

英文摘要：

The design uses embedded system structure which communicates with external by using TCP/IP protocol and communicates with internal by using CAN bus. In this way, the flexibility and the reliability are improved effectively. The structure has been used to develop animalcule gross detect system, and tackes good effect. The result is fairly promising.
