摘要：针对智能控制布点间的通讯必须要有统一的协议标准的问题，研究了一种应用于“基于Linux嵌入式系统智能控制节点”的通讯应用协议，进而形成一定的标准，以满足不同用户接入控制节点的需求。此协议主要借鉴网络通讯协议的分层方式对节点间的交互消息进行了分层处理，分层协议栈主要包括：应用层、网络层和数据链路层。实践结果证明，该应用协议可靠、灵活性好、可扩展性强、易于实现和维护。

Abstract: Aiming at the necessity of unified agreement standard in communication among intelligent control nodes, a kind of communicationapplication protocol of intelligent control nodes based on Linux embedded system was introduced. A standard was formed to satisfy the needs of different users access to control nodes. The interactive information was sliced between the nodes by using the layered mode of network protocol as a reference. The application layer, network layer and data link layer were included in the layered protocol stack. The practical application results show that the protocol is reliable, flexible, expandable and easy to achieve and maintain.
