Types and Functions of Data Acquisition Terminals

Data acquisition terminals come in various types, including sensors, drones, and smart devices. These terminals can collect different types of data, such as soil moisture, temperature, light intensity, crop growth status, and livestock health status. At the same time, they can achieve real-time data transmission and remote monitoring, allowing farmers to grasp farmland conditions and crop growth status anytime.

Sensors are the most basic and common devices among data acquisition terminals. They monitor various environmental parameters in real-time by detecting physical quantities and converting them into measurable and processable signals.

In agriculture, sensors can be installed in fields to monitor environmental parameters such as soil moisture, temperature, and light intensity. These parameters are crucial for crop growth, and the data collected by sensors can help farmers better understand the farmland environment, leading to more accurate decisions.

Drones are increasingly used as data acquisition terminals in agriculture. They can carry various sensors and imaging devices to monitor farmland from the air. By collecting images of farmland, drones can identify crop growth conditions and pest occurrences.

Drones can also carry smart devices, such as spraying equipment, to achieve precise fertilization and pesticide application. This not only improves agricultural production efficiency but also reduces the use of pesticides and fertilizers, lowering environmental pollution.

Smart devices are another major category of data acquisition terminals. They integrate components such as sensors, controllers, and actuators to achieve real-time monitoring and control of farmland conditions. For example, smart irrigation systems can automatically adjust irrigation amounts based on soil moisture and crop water needs, ensuring crops receive adequate moisture;

Smart greenhouses can automatically adjust indoor environmental conditions based on light intensity, temperature, and other parameters to provide the best growing environment for crops. The application of these smart devices not only enhances the automation level of agricultural production but also significantly improves crop yield and quality.

In addition to these three main types of data acquisition terminals, there are other types, such as handheld data acquisition terminals and fixed data acquisition terminals. These terminals typically feature portability, ease of use, and high precision, making them suitable for data collection tasks in various complex environments.

How New Farmers Use Data Acquisition Terminals to Develop Agriculture

Soil Monitoring

New farmers utilize data acquisition terminals to monitor soil moisture, temperature, pH, and nutrients in real-time. By monitoring soil moisture, they can reasonably adjust irrigation systems to ensure crops receive sufficient water at different growth stages. At the same time, based on soil nutrient content, they can apply precise fertilization to improve fertilizer utilization and reduce resource waste. For example, when planting vegetables, soil moisture sensors monitor soil moisture in real-time, automatically activating the irrigation system when soil moisture falls below a set value, while adjusting fertilization amounts based on soil nutrient content to ensure the necessary nutrients for vegetable growth.

Crop Growth Monitoring

Data acquisition terminals can monitor crop growth conditions, such as plant height, leaf area, and fruit size. By analyzing this data, they can detect abnormalities in the crop growth process and take corresponding measures to adjust. For example, by monitoring plant height and leaf area, they can determine whether crops are growing normally; if yellowing leaves or slow growth are detected, they can analyze the causes and adjust planting strategies in a timely manner.

Environmental Monitoring

Data acquisition terminals can monitor agricultural environmental factors such as air quality, temperature, humidity, and light. By monitoring these environmental factors, they can provide favorable conditions for crop growth. For instance, in a greenhouse, they can adjust ventilation, shading, and heating equipment based on the monitored temperature, humidity, and light to ensure crops grow in suitable conditions.

Production Process Records

Data acquisition terminals record the entire process of agricultural products from planting, processing to sales, including planting processes, fertilization, pesticide use, harvesting, and processing. This information can be stored and transmitted in the form of QR codes or labels, allowing consumers to scan the QR code to obtain detailed information about the agricultural products.

Quality Testing

Data acquisition terminals can perform quality testing on agricultural products, including testing for nutritional components, pesticide residues, and heavy metal content. By analyzing these testing data, they ensure that agricultural product quality meets standards. For example, during the processing of agricultural products, they can test for nutritional components and pesticide residues to ensure the safety of agricultural product quality.

Traceability System Establishment

By establishing an agricultural product quality traceability system, consumers can learn about the origin, production process, and quality testing of agricultural products. This not only increases consumer trust in agricultural products but also helps new farmers enhance quality control and improve the competitiveness of agricultural products. For instance, consumers can scan QR codes to obtain detailed information about agricultural products, including production processes and quality testing.
