The smart farmland solution integrates technologies such as sensors, automated control, Internet of Things, and mobile internet to continuously monitor environmental factors such as soil, moisture, light, and heat that are closely related to the observation of crop growth and its phenology, and to monitor field irrigation electromagnetic fields. The valve performs remote intelligent automatic control and realizes remote timing and quantitative irrigation, so as to provide new scientific and technological means for agricultural production, increase yield, risk prevention and control, and disaster prediction. Equipped with a high-definition video surveillance system, users can directly view the growth of crops remotely, effectively reducing maintenance costs and labor costs.
1.Smart farmland management system is composed of four modules: farmland environmental data monitoring system, automatic irrigation system, video image acquisition and monitoring, remote data display and control management platform.
2.Farmland environmental data monitoring system: the farmland environmental monitoring system uses various sensors to collect soil pH value, soil electrical conduction, wind speed, wind direction, light, rainfall, photosynthetically active radiation, air pressure, air temperature and humidity and other environmental indicators, and uploads data to the cloud database through Lora / Nb IOT gateway for remote data display and control management platform.
3.Automatic irrigation system: the automatic irrigation system consists of IOT wireless irrigation automatic controller, IOT wireless control node, IOT wireless control node and corresponding control software. Through the above controllers and control nodes, the water pump and solenoid valve are controlled to realize the remote automatic control of outdoor farmland irrigation. Combined with the monitoring data of soil moisture by the farmland environmental data monitoring system, the irrigation controller can not only carry out remote irrigation operation on farmland, but also realize fixed area, fixed time and quantitative irrigation on demand through user settings, which greatly saves the input of water and fertilizer, reduces the labor cost, improves the utilization rate of water and fertilizer, and reduces the production input cost.
4.Video image acquisition and monitoring: high definition cameras are deployed in the field crop planting area to remotely transmit real-time video information or regular photos to the remote management center through Internet / 2G / 3G / 4G / GPRS and other networks. Production managers can timely understand the situation of agricultural production site through video and picture information, and timely release production guidance and pest warning information, so as to ensure safe and efficient production To improve the level of information management of agricultural production.
Remote data display and control management platform: the remote data display and control management platform can process and graphically display the data collected and uploaded by the farmland environmental data monitoring system, and users can view and control the outdoor field planting environment data anytime and anywhere through mobile phones, iPad, PC and other terminal devices. Combined with the online monitoring data and the irrigation threshold designed by users, the remote management center can intelligently control the irrigation solenoid valve or water pump to keep the best soil moisture content. The user can set the alarm threshold of each index parameter. When the crop planting environment and irrigation water are abnormal, the management center will timely inform the user to take measures through SMS alarm mode, and timely grasp the relevant meteorological information, so as to reduce the economic loss caused by the abnormal environment.
