The Research And Development Of Handy Terminal For Cow's Information Collection Based On RFID And WSN

With the rapid development of dairy cow breeding industry, many large-scale cow farms used management system software to manage breeding datas. This way greatly improve the modernization level of dairy cow management, but the data collection method compared to traditional manual records still not much improvement and have many issues. For examle the efficiency is very low, may result in loss of data recording and storage updates lagged behind. In this papaer, we studies and designs one kind of portable handy terminal device used for cow identification, data collection and transmisson.The main research content and the conclusion are as follows.(1) According to application conditions, we propose to combine embedded technical, RFID technology and WSN technology as the basis of handy terminal development and take embedded design methods and modular design approach to design the system scheme; the design contents include bottom module, RFID module, Zigbee module and keyboard module.(2) The development of hardware need to complete power circuit design, reset circuit design, USB interface circuit design, LCD interface circuit design, JTAG interface circuit design, Keypad interface circuit design, RFID interface circuit design and CC2430 application circuit design, finishes the making, welding and test of the circuit at last.(3) The development of software require to complete the transplantation of u-boot, construction of Linux kernel and Yaffs file system, program Keypad hardware drivers, RFID communication program, Zigbee wireless communication program, QT interface communication procedures and data acquisition software.(4) After design and implementation of handy terminal, we need to perform a systematical test in laboratory and cow farms. The content includes: RFID read and write test, data collection test, data transmission test and wholly performance test. The results show that the system features could meet the design requirements; the overall performance of the device is expected to achieve the design objectives.
