摘要: 随着工作环境的日益复杂,现代通信对于可靠性的要求越来越高。现在存在的一些串行通信协议比如RS-232和RS-485等内容简单,方便实现,但是在传输规范方面没有做很详细的规定,因此传输的可靠性不能得到很好的保证。为了提高串行通信的可靠性,在RS-232协议的基础上提出了一种全新的串行通信协议,定义了完备的帧格式,引入CRC校验、超时重发等一系列查错容错机制,通过仿真验证,证明了该通信协议的可靠性。

关键词: 循环校验码, 串行通信, 帧格式, 通信协议

Abstract: With the increasing complexity of the working environment, the reliability of modern communication needs higher and higher requirements.Some serial communication protocol such as RS-232 and RS-485 which have simple content are easy to realize,but transmission reliability can not get a good guarantee due to the simple transmission specification. In order to improve the reliability of serial communication, a new protocol with complete frame format, CRC, retransmission and a series of error tolerant mechanism,which is based on RS-232 protocol is proposed in this paper. The reliability of the protocol is verified by the simulation in this paper.

Key words: CRC, serial communication, frame format, communication protocol
