2.设计方案的总体结构
无人飞行器温度巡检装置的结构框图如图1所示。
无人飞行器温度巡检装置的结构框图
本设计采用FPGA作为核心芯片,电源电路供电后,信号调理电路通过铂电阻传感器PT100将采集的电压信号通过放大器放大后送给A/D采样电路,A/D采样电路通过采样把模拟信号转换为数字信号后送给FPGA进行处理,处理数据后FPGA自动把处理结果送出,通过液晶显示并且与键盘电路设定的值进行比对,如果超出设定值范围,FPGA送出信号,使得蜂鸣器电路报警,继电器电路响应,启动加热装置,图1给出了系统的整体框图。
3.硬件电路设计及实现
按照系统的功能要求,装置的硬件电路依据其功能划分为信号调理模块、A/D采样模块、FPGA小系统模块等部分。
3.1 信号调理模块
系统采用惠斯通电桥接入铂电阻传感器PT100信号,如图2所示。
信号调理模块电路
图2中INA、INB之差与PT100阻值变化呈线性关系,通过将INA、INB变化值采样再对应铂电阻传感器P100刻度表即可换算得到实测温度。考虑到铂电阻传感器PT100探头产生的信号非常微弱,很容易受到噪声干扰,所以放大电路选择单运放构成的仪表放大器。仪表放大器拥有差分式结构,对共模噪声有很强的抑制作用,同时拥有较高的输入阻抗和较小的输出阻抗,非常适合对微弱信号的放大。图2中R3,R4,R5,R6,R7,R8均采用低温漂的精密电阻,R2为多圈精密可调电阻。通过电路可以计算出:
由式(1)可看出,通过增减R8的阻值即可改变增益,得到理想的放大倍数。A/D采样模块
系统选用AD7476作为采样芯片。该芯片是12位低功耗逐次逼近型ADC,采用单电源工作,电源电压为2.35V至5.25V,高吞吐速率可达1MSPS,完全满足本系统的采样精度和速度的要求。该芯片内置一个低噪声、宽带宽采样保持放大器,可处理6MHz以上的输入频率。
AD转换过程和数据采集过程通过CS和串行时钟SCLK进行控制,从而为器件与FPGA接口创造了条件。输入信号在CS的下降沿进行采样,而转换同时在此处启动,转换速率取决于SCLK的时钟频率。图3为AD7476的典型接线电路。

4.软件设计
温度巡检装置的软件以VHDL语言为基础,采样模块化的设计思路编程,分为液晶显示模块、AD采样模块、键盘输入模块、报警模块和PWM控制模块模块。图4给出了各模块之间的关系图。
