The Wireless Data Acquisition System Based On Arm_linux

Microprocessor technology, sensor technology and wireless communications technology, promote wireless data acquisition system of production and development. Data collection techniques are widely used in radar, communications, remote sensing remote sensing and other fields. Access to information in all, the high-speed data acquisition for a wide range of needs. Measurement and Control Technology With the development of intelligent data acquisition system and network level to a higher demand. And as a result of the rapid development of communication networks, mobile communications and the practical application of the combination of GPRS-based network enables wireless data transmission system has become the most remote areas of wireless communications applications. This issue will be widely used in embedded controllers into the design of data acquisition system, combined with excellent GPRS network characteristics, the realization of a low-power, intelligence, networking, hardware and software tasks can be measured in accordance with an appropriate reduction of the specific wireless high-speed data acquisition platform.The design uses 32-bit ARM processor S3C2410 as the core devices, with FPGA + DDR SDRAM high-speed data acquisition module, GPRS data communication module, embedded in the Linux operating system and application software support, to achieve high-speed digital acquisition, digital wireless on-site data network data acquisition system. The platform of the field data collected for a variety of main sensor analog output voltage. Data acquisition front-end FPGA module of high-speed AD converter to control the input of the analog signal acquisition, the DDR SDRAM memory constituted by the large-capacity cache, embedded systems go through. In a variety of microcontrollers and then the results will be stored in the SDRAM memory ARM systems, the final module in the ARM system GPRS expansion module, the data will be collected through the GPRS network to send out.Because of its open-source Linux as well as powerful features such as network functions, in many embedded network devices have broad applications, and other embedded operating systems, it has more advantages. Therefore this issue as the hardware platform operating system. ARM-based embedded data acquisition and processing system structure clear, common good, scalability, and a variety of embedded applications for the provision of a complete set of hardware and software solutions in the field of industrial measurement and control with more extensive application prospects.
