基于422串口的无损数字通讯方法

Precise digital communication method based on 422 serial port

在很多实际工程应用和半实物仿真环境中,需要在一些实物或设备之间建立实时的数字通讯通道,通道负责将一些高精度的数据从一个实物或设备传送到另一个实物或设备。纵观现有的工程实现方法,它们在保证了上述通道实时性要求的同时,往往损失了所传输的数据的精度。提出了一种新的数字通讯方法,不仅具有快速性的特点,而且可以确保所传送的数据没有任何的精度损失,保证了数据的完整性。

Real time digital communication channel, used for transferring data from one hardware or equipment to another hardware or equipment, always needs to be established in many actual applications and hardware-in-the-loop experiments. Although many exist methods were suitable for the demand of critical time, but they always also lost data precision at the same time. A new method of digital communication was put forward. Not only the speed of transferring data is guaranteed, but also there is no longer precision losing in the method.
