基于 SN65HVD255的 CAN 无极性通讯技术及其在空调通讯系统的应用

摘要

This paper describes the system structure and design ideas of a SN65HVD255 and ISO7230M based non-polarity CAN com-munication technology, and its application in air-conditioning distributed control system. Featuring in low cost and high reliability, this technology can be wildly used in air-conditioning and other industrial control areas.%本文介绍了一种基于 SN65HVD255和 ISO7230M 芯片的 CAN 总线无极性通讯技术的工作原理和总体结构，及其在空调分布式控制系统的应用。该无极性通讯技术具有低成本、高可靠性等特点，可广泛应用于空调及其他工业控制领域。
