基于4G通信的土壤信息采集终端研制与试验OA

To address challenges with traditional soil monitoring methods,such as complex wiring,poor real-time performance,and limited coverage,an intelligent soil information collection terminal based on 4G communication has been developed.Terminal uses an STM32 CPU and integrates multi-parameter soil sensors with a 4G communication module,enabling automatic and real-time collection of key soil parameters including temperature,moisture,electric conductivity,and pH.As a core node in a wireless sensor network,data collection terminal transmits data directly and stably to a remote cloud-based monitoring platform via 4G network,enabling long-term,continuous,and centralized monitoring of soil moisture conditions across wide areas.Test results have demonstrated that termin-al offers reliable data transmission and low power consumption.It effectively addresses monitoring challenges in remote farmlands or areas lacking network infrastructure.Terminal provides efficient and low-cost technical equipment for precision agriculture and environ-mental monitoring,significantly enhancing intelligence and informatization level of soil information collection.
