IOT News

The smart greenhouse IoT system can monitor in real time the air temperature and humidity, soil moisture and temperature, carbon dioxide concentration, light intensity, and video images inside the greenhouse, and remotely control the status of greenhouse equipment such as wet curtain fans, spray irrigation, internal and external shading, top windows and side windows, and heating and supplemental lighting. It can also implement autonomous alarms to form an intelligent greenhouse management method, ensuring a suitable environment inside the greenhouse and the safe growth of crops, and promoting more high-yield and efficient agricultural production.

System Structure

The on-site control node consists of sensors (temperature and humidity sensors, soil moisture sensors, light sensors, carbon dioxide sensors, etc.), environmental control equipment (internal shading, external shading, fans, wet curtain water pumps, solenoid valves), and PLC control cabinets. The PLC receives the environmental parameters output by the sensors and outputs control signals to the environmental control equipment to achieve automated control, effectively reducing labor costs and workload.

The data communication terminal is centered on the industrial intelligent gateway, which can connect to PLCs, sensors, cameras, and other equipment in the greenhouse, perform protocol parsing and data acquisition, and connect air temperature and humidity, soil moisture, soil pH value, light intensity, carbon dioxide concentration, and the operating status of each environmental control device to the greenhouse management platform through 5G/4G/WIFI/Ethernet and other methods.

The greenhouse management platform can display the status parameters of each greenhouse in the form of visualized 2D/3D configuration. Management personnel can remotely monitor the environmental parameter reports and equipment operation dashboards of each greenhouse through mobile phones and computers, and receive alarm notifications, so as to quickly locate abnormal faults and take measures, manage and control in a timely manner to ensure environmental safety and agricultural production safety, and achieve refined management of agricultural production.

Functional Features

The gateway implements multi-center data transmission and can achieve centralized monitoring and display of greenhouses on mobile phones, computers, and on-site large screens, allowing users to understand information such as location distribution, operating parameters, and alarm frequency anytime and anywhere.

Display the monitoring parameters of each greenhouse in real time, display data such as air temperature and humidity, soil moisture, soil pH value, light intensity, and carbon dioxide concentration in the form of real-time curves, and support retri and filtering.

Establish an equipment dashboard to display in list form the operating status, working mode, switch time, and alarm information of each device in the greenhouse, and support remote control operations such as starting and stopping valves and turning water pumps on and off.

Flexibly configure alarm rules to set reasonable alarm management modes for different greenhouses. When abnormalities occur, alarms are automatically sent through WeChat, SMS, email, and other methods, enabling rapid location, diagnosis, and measures.
