The rapid development of the intelligent industry has brought new opportunities for the development of modern agriculture. Modern agriculture relies heavily on the greenhouse environment, which is an independent facility that creates an environment for crop growth. Due to the cultivation of crops, temperature, humidity The requirements for parameters such as CO2 concentration are very high, so greenhouse management needs to introduce more advanced automation control systems. Applying automation control systems to greenhouses can make the collection of atmospheric, soil, light, CO2 concentration, wind direction, wind speed and other parameters in the greenhouse more accurate, thereby simulating the most suitable environment for plant growth in the greenhouse. After analyzing the data through the control system, some controllers can be used for automation control to adjust to an environment suitable for crop growth. Using technological means to reduce labor intensity and improve productivity is the most effective way to solve rural population aging, alleviate rural labor shortage, and promote modern agricultural construction.

The overall goal is to establish a system that integrates comprehensive visualization, automated control, functional area control, soil moisture monitoring, automatic warning rule execution, product traceability, expert remote guidance, and other related content, based on equipment linkage, 5G communication transmission system as guarantee, computer network system as support, and decision support system as core, using advanced data collection, transmission, and processing methods. The system will guide large-scale and standardized greenhouse production, achieve increased production and efficiency in intelligent greenhouses.

1、 Software system

The system implements functional layout according to the agricultural production stage, with a systematic management concept and customized software system according to customer needs. Through intelligent management such as agricultural visualization remote diagnosis and control, disaster warning, etc., agricultural production automation and intelligence have been achieved. Being able to establish standardization for agricultural production, so that agriculture can be produced in a standardized manner like industry.

The system is divided into two ends: computer and mobile. The computer end has rich functions, while the mobile end is easy to operate. The main functional modules include farm management, equipment management, planting and production, data analysis, expert guidance, product traceability, pest and disease database, warehouse management, and other modules. We can also customize modules such as OA system, smart agricultural machinery, crop image library, etc.

Functional modules can be customized according to customer needs.

2、 Equipment control

According to the various data rules set for smart devices, sensors automatically collect data within the area. The sensors can sense the measured information and convert it into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. The device itself has analytical capabilities, executes rules locally, and feeds back information to the cloud server after execution. The server analyzes feedback information to determine and then sends commands to other smart devices.

3、 Intelligent monitoring

1. Soil monitoring

Multiple sensors are used to monitor the soil layer by layer, with a monitoring depth of 1-2 meters. The monitoring data includes pH, ESP value, total nitrogen, total phosphorus, total potassium, organic matter, humus, etc. The project conducts soil testing and formula fertilization throughout the entire area to improve product quality and yield, and reduce resource waste.

2. Environmental monitoring

Using a 16 element outdoor monitoring station, analyze real-time important environmental information such as gas, radiation, and integration. Monitoring data includes: atmospheric temperature, humidity, wind speed, wind direction, carbon dioxide, light intensity, sunshine hours, evaporation, rainfall, etc., which are uploaded to the system platform in real-time and permanently saved.

3. Insect monitoring

By utilizing various systems such as light, electricity, numerical control technology, Internet of Things systems, and meteorological systems, the far-infrared automatic processing of insect bodies can be achieved. Without human supervision, the system can automatically complete tasks such as insect attraction, pest control, collection, packaging, and drainage.

4. Water quality monitoring

Monitoring is carried out through an automatic water quality monitor, which is equipped with pH value sensors, ESP value sensors, pressure water level sensors, water temperature sensors, etc. It supports multiple network communication, uploads data every 10 minutes, permanently saves it, and when the preset online time is reached, the system will issue an alarm and immediately issue drainage instructions, achieving the purpose of real-time monitoring.

4、 Intelligent greenhouse water and fertilizer integration

Integrated water and fertilizer technology utilizes a pressure irrigation system to mix soluble solid or liquid fertilizers into a fertilizer solution with irrigation water. The water is then supplied through a controllable pipeline system, allowing the water to form droplets that evenly, regularly, and quantitatively infiltrate the root development area of crops. This ensures that the soil in the main root zone remains loose and in a suitable moisture state. At the same time, based on the fertilizer requirements of different crops, soil environmental conditions, and water requirements during different growth stages, the entire growth period demand design is developed, and water and nutrients are directly supplied to crops in a timely, quantitative, and proportional manner. Compared to traditional irrigation, the water-saving effect is very significant; The organic combination of water and fertilizer saves fertilizer, water, and labor, ensuring the water and fertilizer needs of crops and significantly reducing costs and increasing efficiency; And it can significantly reduce pests, diseases, and weeds, reduce pesticide use, which is the technical core of standardized production and significantly improves quality.

5、 Expert remote guidance visualization

Experts can analyze and judge the data uploaded to the system platform through indoor monitoring equipment and high-definition images from remote cameras. Quickly develop facility pest and disease warning plans, and obtain technical guidance and services from agricultural experts without leaving home.

6、 Command Center

The overall command center is the core hub of the entire project area, commanding and scheduling the operation of all equipment within the project area. The command center is planned to build a main control cabinet, chief control valve, LES large screen, etc. The system realizes the collection of front-end video, audio, and multimedia information resources that need to be monitored in the project area through network and communication transmission to the comprehensive control platform of the monitoring command center, achieving resource sharing and unified processing of information.
