Abstract:
In the warehouse management system, the environment inside the warehouse has a direct impact on the storage time and goods quality, therefore it is particularly important to obtain real-time and effective information of the warehouse environment. The traditional warehouse management system primarily depending on workforce in complex warehouse information collection can obtain information neither in real time nor at an affordable cost.
To address the problem, this paper proposes a warehouse environment monitoring system based on ZigBee and NB-IoT (Narrow Band Internet of Things), which can obtain real-time and accurate information inside the warehouse, effectively improve the efficiency of the warehouse management system, and save costs. The system applies the combination of ZigBee technology and NB-IoT technology on the warehouse management system, and adopts ZigBee technology to set up the wireless sensor network. ZigBee nodes are used as the terminal devices to collect information, while NB-IoT module is used as the gateway of the monitoring system to upload the monitoring data of the whole wireless sensor network. The system is designed with low power consumption, and has the function of monitoring node positioning, thereby monitoring the real-time environment information of multiple nodes inside the warehouse. In addition, the system introduces the anti-false alarm mechanism, and is featured with low cost, low power consumption, and high reliability.
