提出了一种计算机和多单片机系统传输速率高、可靠性强的串行通信的新方法。基于32位Windows环境，采用多线程技术实现串行通信的实时性，有效地解决了传统串行通信中的迟滞性和不可靠性，提出多线程技术下上位机和196系列多单片机系统通过RS-485总线实时远程通信的新手段，给出完整规范的通信协议及相应的软硬件实现。
A new method of serial communication with high transmission rate and high reliability of computer and multi-MCU systems is proposed. Based on the 32-bit Windows environment, using multithreading technology to achieve the real-time serial communication, effectively solve the hysteresis and unreliability in the traditional serial communication, proposed multithreaded technology under the host computer and 196 series of single-chip microcomputer system through the RS -485 bus, a new means of real-time remote communication, given a complete specification of the communication protocol and the corresponding hardware and software implementation.
