基于FPGA控制单片机接口的远程监测系统

Remote Monitor System Based on FPGA Controlling MCU Interface

介绍了基于FPGA控制单片机接口实现远程监测系统的设计。该系统采用双CPU结构,下位机负责采集现场数据,上位机控制和监测下位机,FPGA作为下位机接口的控制芯片实现现场数据采集、数据液晶显示等工作。通过RS485总线实现上下位机的远程数据通信。

The design of remote monitor system based on controlling MCU interface with FPGA was introduced. Two CPU was used in this system, The terminal CPU was used for local sampling data, and the local CPU was used for controlling and monitoring the terminal CPU, The FPGA as terminal controlling MCU interface was used for sampling and displaying local data etc. Via this way, it transmitted the data and instruction in long distance. RS-485 bus was used as the method of communication.
