| 摘 要： | 当前,工业控制设备都朝向复杂化、多元化发展,其中以主板卡拖载多块子板卡最为流行。主板卡与子板卡之间的通信协议多种多样,如TCP/IP等,然而这类协议复杂,移植困难,就板级通信来说,属于短距离通信,信道不易受干扰,从而寻求一种简单、可靠的板级通信协议成为一种必要。本文就上述各种需求,研究出一套易于移植、并可扩充的基于485总线的通信标准协议,便于在单片机上实现。

| Abstract: | Nowadays, industry control equipment becomes increasingly complex. The most popular one is using one main board to drive multiple sub-boards. There are many kinds of communication protocols working between the main board and sub-boards,such as TCP/IP. However, these kinds of protocols are so complex that they are hard to port from one system to another. And communication between boards is a short distance communication that is hard to be disturbed. So a simple and credible protocol is necessary for such equipment. This article designs an easily-portable, flexibly-expandable communication protocol, which is based on Bus 485. |
