基于ZigBee技术的数据汇聚终端设计及应用

摘要

For the dififculties of measured data acquisition and convergence in smart city construction, data convergence terminal equipment based on ZigBee technology is designed. With the low power consumption characteristic of ZigBee, two kinds of data convergence terminal-selection-modes(basic and enhanced)are provided and three kinds of power source handling solutions are planned, so as to collect the measured data wirelessly and upload them to the information platform. The large amounts of data are converged to the terminal equipment and then applied in smart cold-chain logistics transport to test the temperature control performance. The experimental results show its effectiveness and stability of the real time data acquisition and convergence.%针对智慧城市建设中涉及的实测数据采集困难和汇聚复杂等问题，设计了基于ZigBee技术的数据汇聚系列智能终端设备，利用ZigBee的低功耗特点，提供了基本型和增强型两种数据采集终端选择模式，规划了三种电源处理方案，实现了实测数据无线采集汇聚上传平台等功能。将大量数据汇聚终端设备应用于智慧冷链物流运输进行温控测试，验证了该终端设备实时数据采集和汇聚的稳定性和有效性。
