奶牛数字化精细养殖系统中读写器的设计

Design of Read/Write Organ in Digital Precision Feeding System for Cow

介绍了基于MFRC632读写芯片和ATmega128单片机的用于奶牛身份识别的RF10读写器的设计方法,给出了读写器主要模块的硬件电路图和软件工作流程。测试结果表明,读写器实现了快速准确识别奶牛个体信息的设计目的,其典型读写距离为52cm,标签在有效感应区域内连续读写出错率约为0.02%,可同时识别多个电子标签,通信稳定可靠,抗干扰能力强。

The design method of RF10 read/write organ,which was used to cow identification and based on MF RC632 read/write chip and AT-mega128 one-chip machine was introduced. The hardware circuit diagram and software working procedure of the main modules in read/write organ were provided. The testing results showed that the read/write organ realized the design aim of rapidly and accurately recognizing individual information of cow,its typical read/write distance was 52 cm and its error rate of continuously reading and writing labels in effective inducing field was about 0. 02%. The read/write organ could recognize multiple electronic labels simultaneously with stable and liable communication and strong anti-interference capacity.
