Precision crop irrigation system for agricultural paddy field based on NB-loT
To address the issue of uneven irrigation during the irrigation process of agricultural paddy crops,a precision irrigation system for agricultural paddy crops based on the NB-IoT Internet of Things is designed.Set up several monitoring points consisting of environmental monitoring modules and soil monitoring modules composed of multiple sensors in the agricultural paddy field crop area,and use each monitoring point to monitor the growth environment and soil information of paddy field crops.Transmit monitoring data to the processing layer through the NB-IoT module on the network layer.The processing layer uses MCU processing module to receive and process monitoring data,construct an optimal irrigation model for agricultural paddy crops,obtain the minimum irrigation amount that meets the growth needs of crops,and then output control instructions through the fuzzy control algorithm in the microcontroller,set the minimum irrigation amount threshold,and transmit the instructions to the application layer.The application layer irrigation equipment controls the switch of the irrigation equipment according to instructions,achieving precise irrigation of agricultural paddy crops.The experimental results indicate that the designed system can accurately irrigate agricultural paddy crops.
