文章设计了一种以ARM单片机为核心、采用GPRS作为无线传输方式的数据采集传输仪,此设备通过串口与传感器进行通信实现采集数据,然后通过GPRS模块把传感器数据发送到控制中心。文章首先介绍了ARM处理器的优点和GPRS无线传输的特点,然后重点介绍了数据采集传输仪的硬件系统,并对设计重点做了详细分析,最后对此数据采集仪的技术优势和潜在应用做了分析和展望。
This paper designs a kind of data acquisition and transmission instrument based on ARM microcontroller with GPRS as the wireless transmission mode. This equipment communicates with the sensor through the serial port to collect data, and then sends the sensor data to the control center through the GPRS module. The article first introduces the advantages of ARM processor and GPRS wireless transmission characteristics, and then introduces the hardware system of data acquisition and transmission instrument, and makes a detailed analysis of the design priorities. Finally, the technical advantages and potential applications of this data acquisition instrument Analysis and Outlook.
