Design of Soil and Water Conservation Monitoring System Based on NB-IoT

Aiming at the problems of soil and water loss and low efficiency of soil and water conservation system in China, a soil and water conservation monitoring system based on NB-IOT is designed and implemented according to the new cellular narrowband Internet of things technology. The system consists of multiple sensor data acquisition nodes, remote monitoring cloud platform and local redundant data storage system; The sensor data acquisition node uses STM32 as the microcontroller, which is responsible for collecting geographic information, temperature and humidity information parameters. The collected information is sent to the local server and the cloud server respectively, and the information collected by the terminal can be obtained in real time by logging in to the cloud server. The actual test results show that the NB module adopts power-saving technology and the current consumption is as low as 3uA, which is in line with the characteristics of low power consumption; At the same time, the one-day packet loss rate is tested, and the total packet loss rate is less than 0.15%, which ensures the accuracy of the data. The difference between the data display time of the test cloud platform and the actual data collection time is within 30ms, which conforms to the real-time characteristics;
