电压采集系统是在工业自动化应用中常见的一种数据采集系统,被广泛应用在工业自动化控制和无线广播发射机控制等领域。基于FPGA设计的含有多路通信串口的电压采集系统是以FPGA为核心器件,通过控制模数转换芯片对模拟电压进行采样,将采样结果通过多路串口传输到多个上位机的一种数据采集系统。该系统通过在FPGA内部复用功能模块的方式,在一个系统中提供多达八个通信串口资源,解决了在需要多个串口同时上传数据的情况下,有些电压采集系统通信串口数量不足的问题。
Voltage acquisition system is a common data acquisition system used in industrial automation applications, is widely used in industrial automation control and radio broadcast transmitter control and other fields. FPGA-based design of multi-channel communication with the serial voltage acquisition system is based on FPGA as the core device, by controlling the analog-digital conversion chip analog voltage sampling, the sampling results through the multi-channel serial transmission to a host of data acquisition system. The system by multiplexing functional modules within the FPGA way, in a system to provide up to eight communication serial port resources to solve the need to connect multiple serial ports at the same time the case of data, some of the voltage acquisition system communication serial number of insufficient .
