Real Time Data Acquisition and Network Topology Research of Wireless Sensor Based on RFID

摘要

In order to improve the warehouse cargo flow and detect the temperature and humidity of storage, the characteristics of the topology of various wireless sensor networks were compared. The tree topology was used. The routing algorithms and routing methods were summarized. A brief description of the networking process was given. Then, the goods data of wireless sensor network and the data collection process of storage environment were designed. The various nodes and the workflow of the RFID system were described. Finally, the warehousing goods data and environmental data were collected and tested. The results showed that the system accurately identified the pallet tag and the cargo tag. At the same time, the storage temperature and the humidity data were monitored in real time. Therefore, the system meets the company's functional requirements for information collection and environmental monitoring of warehousing goods. The effect is good.
