基于RFID与ZigBee的羊场养殖信息管理系统

为了选育性状优良的羊进入核心种群,将RFID射频识别、ZigBee无线通信与ARM嵌入式技术相结合,研制了一套羊场养殖信息管理手持终端。手持终端包括基于S3C6410处理器的ARM核心板、125 kHz RFID阅读器、基于CC2530芯片的ZigBee无线通信模块以及多功能底板。软件开发过程中,构建了包含设备驱动的Linux系统环境,利用Qt/Embedded的信号/槽机制实时接收RFID数据,基于OSAL操作系统的ZigBee2007协议栈实现ARM与ZigBee网络之间的通信,在Qt中设计触摸屏图形界面以及串口通信、通信指令、软键盘、蜂鸣器、中文显示等后台程序,具有日常管理、育种管理及疫病管理等模块功能。现场测试结果表明,手持终端能够实时采集、录入、存储、拷贝、查询养殖信息并通过ZigBee无线网络与上位机通信,可满足羊场信息化管理的需要。

Development of Handheld Terminal for Sheep Breeding Information Management Based on RFID and ZigBee

In order to select the sheep with better characters than others into the core group, a handheld terminal, used for sheep breeding information management, was developed by combining RFID, ZigBee wireless communication and ARM. The handheld terminal was mainly designed with ARM core board based on S3C6410 processor, 125kHz RFID reader, ZigBee wireless communication module based on CC2530 chip and multi-functional baseboard. In the process of software development, the embedded Linux system environment with the hardware device drivers mentioned above were established. ARM was used to receive real-time RFID reader data by using Qt/Embedded signal/slot. Through running ZigBee2007 protocol stack under the OSAL operating system, the communication was realized between ARM and ZigBee network. Some background application programs, such as the touch screen interface and serial communication, communication instruction, soft keyboard, buzzer, Chinese display etc., were designed based on Qt, which had functions of daily management, breeding management and disease management. Field test results showed that the handheld terminal could collect, enter, store, copy and query sheep breeding information in real-time, and communicate with the host computer through ZigBee wireless network. It was proved that the developed system could meet the needs of sheep information management.
