中文摘要:
      针对人工完成的班级考勤任务存在劳动量大、效率低、实时性差和管理粗放等问题,设计了一种基于ZigBee和GPRS网络的班级考勤系统,由RFID读写器和ZigBee通信模块组成的终端节点对以nRF24LE1为核心的电子标签进行读写,电子标签信息由ZigBee GPRS网关传输至GPRS网络,再经Internet网络上传至监控中心,实现班级考勤任务的远程监测和管理。介绍了系统的总体结构,给出了WSN网络各功能节点的软硬件设计及上位机软件设计。系统测试表明,该系统能够对电子标签进行远程识别,且电子标签信号发射距离为15~65 m,满足系统设计要求,具有良好的应用前景。
英文摘要:
      Traditional class attendance task is completed manually, which appears many problems such as large amount of tasks, low efficiency, poor real time performance, system is designed based on ZigBee and GPRS network. The terminal nodes composed of RFID reading writing device and ZigBee communication module can control reading and writing of electronic tag whose core is nRF24LE1. Information of electronic tag is transferred from ZigBee GPRS gateway to GPRS network, and then is uploaded to the monitoring center according to the Internet network to come true remote monitoring and management of the class attendance task. The overall structure of system is introduced, and the WSN’s software and hardware design of each function nodes and the upper machine are given in this paper. The test of system shows that it can identify the information of electronic tag remotely, and signal launch distance of electronic tag is about from 15 to 65 meters, which is met requirement of system showing a good application prospect.
