基于FPGA的多通道串口数据采集与传输设计

Designing the Data Collection and Transmission System of Multi-Serial ports Based on FPGA

摘要:

针对多通道串口数据的采集与传输现实需要，提出了一种基于FPGA的多通道串口数据采集方案。通过对多路串口数据的同时采集、缓冲及打包的数据流处理思想，采用FPAG+多串口+USB的硬件框架及总线不同速率的传输算法，实现了多路串口数据的采集与传输。为了验证设计的有效性，设计了6路串口同时传输的试验方案，最终通过试验满足预期要求，达到多路串口同时采集及传输的目的。

Abstract:

Multi-channels serial data transmission is a new requirement for modern industrial control transmission, and the traditional industrial controller due to the limited number of interfaces, often difficult to meet the requirements. For multi-channel serial ports data collection and transmission of real needs, a data acquisition program based on FPGA for multi-channel serial ports was presented in this paper. The idea of simultaneous acquisition, buffering and packet data processing for multi-channels serial data, and the structure of hardware frame based on FPAG + multi-serials port + USB and bus different rate transmission software processing algorithm was introduced to achieve a multi-channel serial data collection and transmission, In order to verify the effectiveness of the design, a software radio platform as the experimental object was taken to design a 6-way serial transmission system in this paper. And finally through the transmission of the source data and the received data comparison found that the two consistent. The results show that the scheme was effective and the test meets the expected requirements, and achieved the purpose of multi-channel serial acquisition and transmission.
