摘要
针对磁力仪传感器,文中设计了以S3C2440微控制器为核心的数据采集与发送系统,实现了三维空间磁场数据的低功耗采集与实时显示。简要介绍磁力仪的原理与数据采集和发送系统电路结构,重点阐述数据采集与发送系统中硬件模块选型,分析系统软件设计思路和重要模块实现细节。通过实验验证,系统将数据采集后得到的磁场信号实时显示在液晶显示屏上,并通过网络模块将磁力仪进行联网,将采集到的数据通过网络发送给上位机处理。同时S3C2440微控制器通过蓝牙模块将采集数据发送给手机终端,用户能够在移动设备上观测磁场实时数据进行相应处理。
Aiming at the magnetometer sensor,a data acquisition and transmission system with S3C2440 microcontroller as the core is designed to realize the low-power acquisition and real-time display of 3D spatial magnetic field data.The principle of magnetometer and the data acquisition and transmitting system circuit structure is briefly introduced.The hardware module selection in the system is emphasized,and the software design ideas and important module implementation details are analyzed.Through the experiment,the system is able to get the magnetic signal from the data to be shown on the LCD screen in real time,and connects network the magnetometer through the network module to,and the data collected is sent to the superior machine via the network.At the same time,the S3C2440 microcontroller sends the collected data to the mobile phone terminal through Bluetooth module,and the user can observe the magnetic field real-time data on the mobile device for corresponding processing.
