基于压力传感器的风速风压测量与
无线数据传输
摘要
风速和风压的测量在很多领域都有很重要的作用, 对于航海、航空、渔业和
农业以及风力发电站等部门来说, 风压和风速则更为重要。在工业生产中,监测
和控制系统均离不开数据信息的传输,很多情况下,由于条件所限,采用普通有
线电缆引出信号是无法满足要求或者跟本无法实现的。
本文设计了用MCS-52系列单片机设计的监测风压风速的数据采集和处理系
统。该系统采用单片机技术,以AT89S52为核心, 把压力传感器安装在步进电机
上,使步进电机带动传感器转动来测量风压,由压力传感器采集数据,单片机接
收并处理数据, LED数码管显示测量风压值。在软件上采用的是由孙以材教授提
出的归十法的算法。来改进测量数据的准确性。描述了系统的硬件设计及软件实
现, 给出了程序编制的基本流程图, 从而降低了系统成本,提高了测量精度。
本文设计了具有无线数据传输功能的测压装置、包括硬件结构设计、软件系
统工作流程及实验结果,该装置以单片机为核心,利用发射器芯片、接收器芯片构
成的无线收发模块PTR8000,设计出数据采集与无线传输系统。该系统的无线数据
采集模块体积小、功耗低、电路构造简单,可以方便地嵌入被监测系统中,利用上
位机实现对被测数据的实时监测。

THE MEASUREMENT OF WIND PRESSURE AND
SPEED BASED ON THE PRESSURE SENSOR AND
WIRELESS DATA TRANSFER
ABSTRACT
The measurements of wind pressure and wind speed have a very important role
in many areas, They are more important in The maritime, aviation, agriculture and
fisheries sectors as well as wind power. In industrial production, monitoring and
control system can not be separated from all of the data transmission. In many cases,
the ordinary cable signal is unable to meet the requirements or can not be achieved
with the present.
This paper designs the data acquisition and processing system of air pressure
monitoring, based on MCS-52 single-puter. And single - puter
technology is adopted in the system. The control center of this system is AT89S52
single-puter. The pressure sensor is installed on the stepper motor, The
stepper motor makes sensor rotating to detect the pressure of wind on the
hardware .The data are collected by pressure sensor, and single chip processor
processes it. LED shows the wind pressure data. The software I propose the algorithm
which by Professor Sun Yicai turns over to Ten-Normalized Algorithm improves the
