基于物联网技术的林区浆果冷链运输智能监测系统

Intelligent Monitoring System of Forest Berry Cold Chain Transportation Based on Internet of Things Technology

以黑龙江省大小兴安岭林区野生浆果的运输过程为研究对象,针对林区野生浆果运输的特殊条件,对浆果运输过程中品质变化监测系统进行研究。采用ZigBee CC2530低功耗短距离射频通信技术,融合多种功能传感器,建立浆果运输状态监测感知节点和汇聚节点,对感知节点进行合理布局,实现对冷链运输车辆运行状态和浆果实时品质的实时监测。采用北斗定位通信卫星的短报文功能,实现车载运输状态数据感知后向后方企业管理平台的传输,以及后台管理人员管理指令向车载系统的传输,建立基于北斗通信的浆果运输过程智能监测管理系统。从而提高运输过程的管理水平,降低运输过程对浆果品质的影响,促进林区天然野生浆果的市场推广,推动林下经济的高质量发展。

Taking the transportation process of wild berries in the forest area of Xing’an Mountains in Heilongjiang as the research object, according to the special transportation conditions of wild berries in forest areas, the paper studied the berry quality change monitoring system during the transportation process. Using the ZigBee CC2530 low-power short-range radio frequency communication technology and integrating multiple functional sensors, it established the berry transportation status monitoring sensing node and aggregating node, and rationally planned the layout of the nodes to realize real-time monitoring of the operation status of the cold chain transportation vehicle and the quality of the berries. Besides, it adopted the short messaging function of the Beidou positioning communication satellite to relay the vehicle transportation status data to the backstage enterprise management platform, and management instructions of the backstage management personnel to the vehicle system and thus establish the intelligent monitoring management system for the berry transportation process based on the Beidou communication system, which could improve the management level of the transportation process, reduce the impact of the transportation process on the quality of the berries, expand market access for natural wild berries from forest areas and propel the high-quality development of the forest economy.
