一种扭矩传感器的无线数据采集系统
摘要
在一些测量领域,人们需要一种能够进行无线数据传送让使用者能够方便观察的仪表系统,例如当
传感器安装在转动或运动部件上时,如何将传感器测得的信号传输到固定的显示仪表或工作站中将成为
人们不得不去解决的难题。
为了适应这些要求,我们在课题中介绍了一种扭矩传感器无线数据传输的设计方法,并给出了利用
单片机进行无线数据传输显示的实例,提出了电路设计中需要注意的问题,给出了程序流程图。该系统
利用编解码技术和软件容错技术,传输可靠,非常适合于无法进行有线传输而需要利用无线数据传输的
区域。
文章分析了该课题的研究内容和意义;介绍了目前无线数据传输国内、外研究概况、水平和发展趋
势,介绍了目前流行的无线数据传输的各种技术标准;文章还分析了现有的各种无线收发模块,对系统
做出了整体设计,系统主要由数据采集、数据处理、无线发射和接收三部分组成。系统的原理设计是扭
矩传感器将扭矩信号转换成电信号,电信号经过调理后送 A/D 转换电路 ICL7135 变换成数字信号再送
入单片机 AT89C51,单片机再控制无线发射电路将数字信号调制高频信号经天线发射出去;接收端对
接收到的高频信号解调后送入数据处理电路,用以显示正确的扭矩数据。

A wireless data transmission system for twisting moment sensor
ABSTRACT
In some realm of measurement, People need a kind of gauge system, which helps the users
observe the measurement conveniently by using of wireless data transmission. For example,
when the sensors are installed in some parts of a device that are turning to moving, The difficult
problem that people have to solve is how to deliver the signal to stationary gauge or working
station.
For adapting to these request, in this programmer we introduced a design of wireless data
transmission and display for twisting moment sensors and give an example using single chip
microprocessor .We also put forward some questions that should be paid attention to circuit
design,We give the program flow chart .The system is reliable as we use encode and decode
technique as well as software fault allowing technique. It is very suitable for the area where wire
transmission cannot be available in that case, we had better to use wireless data transmission.
The article analyzes the research contents and meaning of the programmer; it introduces the
trends of the wireless data transmission of the current situation and the level and development at
room and abroad. It introduces the popu
