Design of Hand-held Terminal for Orchard Management Based on RFID

A hand-held terminal for orchard information collection is designed, which can identify and realize individual plant precision management based on RFID technology. The equipment adopt RS-485 serial bus and MODBUS communication protocol as the general interface for different sensors, to achieve data acquisition requirements including the fruit tree image, air temperature and humidity, soil moisture etc. Meanwhile, build the cloud database that use SIM900A wireless communication module for real-time upload of data, and it can generate nephogram and data analysis report through GPS positioning. Field test results showed that the terminal has high detection accuracy with worked stably and simple operation. Finally, it realized the sharing of sensor information and automatic data acquisition in orchard, with great application and promotion value.
