基于FPGA的多点温度无线采集系统

为了对国防、天文和工业领域内特殊场合进行多点实时温度监控,设计了基于可编程逻辑门阵列FPGA(field programmable gate array,FPGA)的多端口并行温度无线实时监控系统.该系统以FPGA为核心,包括温度信号采集、数据存储、数据传输、实时温度值的动态显示4个部分.系统采用多个智能温度传感器对多个测试点进行并行温度的采集,并将采集到的温度信号进行模数转换,同时缓存到FIFO(first in first out)中,FIFO里的数据在FPGA的控制下通过蓝牙模块传输到PC端.PC端完成对实时温度的显示和过温报警.各测试点的温度实时显示在PC界面上,工作人员不仅不用亲临现场就可以实时对各个监测点的温度进行监控,还可以通过记录的历史数据,进行数据分析.

Temperature wireless acquisition system based on FPGA

Temperature wireless monitoring system for multi testing point based on FPGA was designed to achieve the goal of the real time monitoring in the field of nation defense,astronomy and industry.This system was constructed with base of FPGA(filed programmable gate array),including acquisition of temperature signal,storage of data,transmission of data and displaying of data.The temperature analog signal is converted into digital one which is stored into FIFO(first in first out) in the smart sensor.The data in FIFO is transferred with Bluetooth protocol to PC.Finally PC is in the charge of displaying of data.With the support of this system the personnel not only can monitor the real time temperature without checking by themselves,but also can analyze the data recorded.
