Digital twin technology makes intelligent agriculture approach the public.

In recent years, with the accelerated emergence of new technologies such as the Internet, technologies such as the Internet of Things, cloud computing and big data have been applied to all aspects of agricultural production, and digital agriculture and smart agriculture have emerged. China's smart agriculture shows a good development momentum, but the penetration rate is still low. One of the reasons is the lack of visual data interaction methods that most farmers can intuitively understand and use.

Digital twinning refers to creating a digital simulation in the information platform by integrating the physical feedback data from various sensors (such as temperature and humidity sensors), supplemented by artificial intelligence, machine learning and software analysis, and this simulation will make corresponding changes according to the feedback.

Shanhai Whale Visualization combines the data obtained by IOT equipment with 3D space rendering through digital twinning technology, which can not only intuitively observe the commonly used index information in greenhouse planting, but also directly control IOT equipment through the switch in large-screen management to realize one-stop intelligent greenhouse management.

The whole intelligent vegetable greenhouse system is divided into four modules, namely, the general situation of the park, environmental monitoring, equipment maintenance and safety management. The data of each module can be connected with the greenhouse system through the built-in data source interface of Shanhai Whale and IOT protocol. The data source supports real-time refresh, and the module content supports customized modification and customized development.

The general situation of the park shows the overall position and status of several greenhouses in the form of a bird's eye view, while the surrounding charts show the types, distribution, yield analysis and output ratio of vegetables.

Day-night conversion

By clicking the switch button between day and night, you can switch the effects of day and night, and show the appearance of vegetable greenhouses at different times through dynamic light and shadow during the day and lighting at night.

Regional connection

Multiple points of interest can be dynamically configured in the 3D model, and specific details can be set for these points. In the exhibition, the specific location and information of different vegetable planting are displayed by clicking on the marking points.

Because the most important information of greenhouse planting in agricultural system is the overall environment and weather environment of greenhouse, the environmental information can present the current environmental state of greenhouse to managers in real time through the integration of thermal sensors and weather data, so as to decide whether it is necessary to adjust the environment by controlling the fill light and fans.

After observing the information in the environment module, managers can directly operate the fan and fill the light through the equipment management module. Fans and fill lights in different greenhouses can be controlled independently by their own buttons.

The security cameras of the whole park are monitored in real time, and the monitoring information is accessed in real time through ONVIF standard, and the specific positions of different monitoring points are displayed in the 3D model. It is very helpful for managers to better grasp the current real situation of the park.

Nowadays, science and technology have become an inseparable part of agriculture. Under the background that agricultural intelligence has become the new direction of modern agricultural development in China, smart agriculture is becoming an important path for rural revitalization and development. In this path, digital twin technology, as a key technology link to make smart agriculture approach the public, will have a brighter development prospect in the future.
