The application of IoT technology in greenhouses can achieve the purpose of improving product quality, regulating growth cycle and improving economic efficiency, especially for efficient and accurate greenhouse management. For large-scale greenhouse facilities, if labor is used to regulate environmental conditions in the greenhouse, a large amount of manpower and time is required, and there are inevitable manual errors. If IoT technology is applied, it can be done in the shortest time with a click of the mouse, and it is very rigorous. This is also an important reason why the industry is optimistic about the application of the Internet of Things in modern agriculture.
The Internet of Things is an information network that is established through sensing devices to realize information transmission and exchange between objects. Intelligent Greenhouse Xiaobian knows that the application of agricultural Internet of Things is mainly to realize the perception, transmission, processing and re-control of agricultural production environmental factors. Agricultural production environmental factors in the planting industry, including water, fertilizer, heat, gas, light, etc. With the development of cloud computing, Internet of Things and big data technology, advanced agricultural management methods have gradually become indispensable for the construction of Internet of Things agriculture. Part of it has formed a new set of agricultural development models. First, the quality can be traced throughout. The second is the analysis of the production planting process. The third is to simplify the complex supply chain, reduce logistics costs, and create conditions for farmers to increase income, agricultural growth and rural stability.
Should fruits and vegetables be watered? Fertilize and fight drugs, how to maintain precise concentration? Temperature, humidity, light, carbon dioxide concentration, how to achieve on-demand supply? Today, "Internet + in Shandong" national online media interviews Shouguang Vegetable Industry Group Modern Agricultural Industrial Park. The problem that this series of crops has been "fuzzified" in different growth cycles, in the Shouguang Vegetable Industry Group Modern Agricultural Industrial Park, has an information-based intelligent monitoring system for real-time quantitative "precise" checks, farmers only need to press a switch, As a choice, you can grow vegetables and raise flowers.
The technical breakthrough to achieve this "accurate" perception is the Internet of Things technology. The Agricultural Internet of Things is recognized by the world as the third wave of the world information industry after the computer, Internet and mobile communication networks. It is based on the premise of realizing the network of people, people and things, things and things. .
From "fuzzy" processing to "precise"
For a long time, in traditional agriculture, watering, fertilizing, and fighting drugs have made farmers rely on experience and experience. Nowadays, in the Shouguang Vegetable Industry Group Modern Agricultural Industrial Park, reporters experience the technology of the “intercepting†agriculture of the Internet of Things.
In this modern vegetable greenhouse, there are not only a variety of advanced equipment and facilities, but also remote control and intelligent management of the greenhouse through the communication network. The mystery lies in the "big house butler" intelligent agricultural management system. Experts told reporters that the temperature and humidity in the shed were collected by wireless sensors, and then aggregated to the remote control terminal. The terminal was transmitted to the service management platform through the mobile communication network. The service management platform summarized the data and then sent the data to the user. In the hands.
Through the “big house housekeeperâ€, farmers can monitor the operation of the vegetable greenhouse through mobile phones, adjust the temperature, humidity and illuminance in the greenhouse in time, and control the automatic roller blinds and automatic sprinklers in the greenhouse with the mobile phone, so that the crops are always at the same time. In the best growing environment.
During the interview, the technician Qin Ran suddenly received a text message on the mobile phone. "The temperature in your No. 8 shed is XX degrees. In order to avoid adverse effects on the growth of tomatoes, please take timely measures. At this time, the temperature outside the shed and the wind are appropriate. It is recommended that you open the skylight and the vent to cool down." After reading the text message, Qin Ran gently squatted on the phone, and the ventilator on the shed wall was automatically opened and ventilated just as she understood her instructions.
“With just one click on the phone, you can complete a series of operations such as watering and ventilation.†Technician Qin Ran told reporters that whether at home or in Shouguang or in the field, as long as they can send text messages, they can remotely control the entire shed. environment of.
Do not leave the shed to give a diagnosis opinion to the vegetable "thousands of eyes"
"Greenhouse butler" can not only remotely control the greenhouse, but also remotely treat vegetables. The application of Internet of Things technology has realized the diagnosis and treatment of greenhouse vegetables from "not leaving the house to leaving the house." In the vegetable greenhouse of Wang Jicheng in Sanyuan Zhucun, Sunji Street, Shouguang City, the reporter took a picture of a little yellowish tomato leaves in front of the "big house butler" camera. In less than a minute, the photo was taken and the photos were sent to the agricultural IoT platform.
About an hour later, Wang Jicheng received a diagnostic message on his mobile phone: "The tomato is suspected to be late blight or gray mold." In addition to the diagnostic information, the text message also gives advice on prevention and control. If the farmer has questions, he can call further for consultation.
"The original management of greenhouses, watering, fertilization all based on experience, now, should not be watered? Should not be fertilized? 'Greenhouse butler' will be reported to you." Wang Jicheng said in the second half of 2011 after the trial of "big house butler" The management of vegetable greenhouses is much easier. "Now it is convenient to treat vegetables with 'clairvoyance'." If there are pests and diseases in the vegetables in the shed, as long as you take photos with the leaves in front of the camera, you can invite agricultural experts from all over the country to give them diagnostic guidance.
The "Greenhouse Steward" intelligent agricultural management system is composed of wireless sensors, remote control terminals and information management platform. It realizes the deep integration of modern mobile communication technology with Internet of Things and Internet technology. The system collects data such as air temperature, humidity and wind speed in real time. At the same time, the user can issue early warning information in time, and when the user receives the warning information, the remote control of the equipment in the shed can be realized through the mobile phone. Farmers can also use remote control terminals to shoot crops that are suspected of being affected by pests and diseases. Experts use the system platform to remotely diagnose and treat and propose prevention and treatment.
Today let`s talk about touch screen laptop. Sometimes people take Yoga Laptop or 2 In 1 Laptop or 360 Laptop as foldable touch screen laptop. Cause the later ones usually with touch screen function.
