Design of the high-speed parallel telemetry data to RS422 long-term transmission

文中主要介绍了一种基于FPGA的将高速并行遥测数据(BMK)转为RS422传输协议进行长线传输的设计。在半实物仿真测试中,要求数据采集系统能够实时且准确的采集数据,将BMK转化为RS422协议传输后可以在保证其精度与速度的同时能够大大延长其传输距离。实际应用表明,此设计具有简捷经济、测试准确的特点,具有很好的实用价值。

This paper mainly introduces a design of the high-speed parallel telemetry data （BMK） to RS422 long-term transmission based on FPGA. In the semi-physical simulation test, it requests that the system of data acquisition can collect data timely and accurately. After the transformation from BMK to RS422 it can extend the distance of transmission and ensure real-time and accuracy. According to practical application, the design has feature of economic and accuracy, has favorable practical value.
