Open Field Smart Planting System of Family Farm

Abstract

In view of the current majority of family farm planting, especially open field planting, the information technology level is lower. Based on the Internet of Things(IoT) technology, an open field smart planting system is designed. STM32 microprocessor is used as the main control chip to design terminal nodes. Each node has the ability to sense the air temperature and humidity, soil humidity, light intensity and other planting environment parameters, and has on-off control function for irrigation and plastic film device. The number of terminal nodes can be increased or decreased to meet the needs of open field smart planting. The terminal node connects the NB-IoT base station through NB-IoT module, and then transmits the sensing data to the cloud server. We can monitor the plants, the planting environment and the working states of the device by the 5G wireless cameral. The user terminal is a smartphone. User can log in to the open field smart planting system through mobile APP, and then interact with the terminal device, monitor the sensing data in real time, watch videos of plant growth status and planting environment, and control the irrigation and plastic film devices remotely. It can also be set to automatic control mode to control the devices automatically. The system has the advantages of simple architecture, convenient deployment and use. The rented cloud server is used for data storage and data processing. Data is transmitted through services provided by operators. It is safe and reliable with low operation and maintenance cost, and is suitable for open field planting of family farm.
