Crops grown in greenhouses are popular in agriculture because they have good thermal insulation and allow people to eat out-of-season food at any time. However, greenhouse planting also has many constraints, such as:
1. Salt accumulation and soil geological change:The use of a large number of chemical fertilizers has caused geological changes in the soil, restricting the growth of crops. At the same time, it also affects the root development of greenhouse crops, reduces the absorption capacity of water and fertilizer, resulting in the lack of nutrition of crops and death; Soil salinization is too high, resulting in crop leaf wither and aging; Poison gases from the soil can also affect crop growth;
2, the problem of drug damage, application time is not allowed:The danger of drug harm is very big, sometimes the symptoms of crops are obvious, sometimes it is invisible, it is difficult to remedy the disease. The timing of pesticide application is not accurate, but also lead to crop deformation, or even death;
3, environmental problems, temperature and humidity environmental hazards:If the temperature and humidity in the greenhouse are not controlled accurately and in time, the optimal planting time of crops will be delayed, and the growth rate will be restricted. At the same time, it will also bring some difficulties to fertilization and drug application.
So, how should we correctly use the greenhouse technology, so that the weak traditional agriculture has become a high-efficiency modern industry? Follow the Xiaobian to understand how the “intelligent greenhouse” is operated!
(a) intelligent greenhouse: intelligent automation
In view of the above three problems, “intelligent greenhouse” has its own way to deal with:
Climate monitoring in greenhouses:By temperature and humidity sensors, environmental monitoring, intelligent hardware devices, such as carbon dioxide monitor within the greenhouses on air temperature and humidity, soil temperature and humidity, and light intensity and so on carries on the collection and monitoring, implement real-time monitor inside the greenhouse environment, improve the response capacity of agricultural production risk of the natural environment, guarantee a healthy, efficient, inside the greenhouse crop growth.
Soil moisture monitoring:Through the soil pH monitor and other equipment, 24/7 uninterrupted monitoring of soil moisture. Field remote monitoring equipment automatically collects real-time soil moisture data, and uses GPRS, 4G, Ethernet and other wireless networks to realize remote data transmission, linkage irrigation and water and fertilizer system, to ensure the stability of soil moisture.
Intelligent greenhouse:Through the detection of temperature, humidity, wind speed, wind direction, PM2.5, carbon dioxide concentration in the greenhouse, with automatic irrigation system, external shading control system and ventilation curtain control system to achieve automatic facility control, intelligent greenhouse system.
(2) the technology behind the intelligent greenhouse
In addition to the above functions, the intelligent greenhouse has automatic irrigation, crop growth, geographic mapping and so on. Behind these intelligent functions are two technologies: LPWAN technology and sensor technology.
Based on LPWA technology and sensor technology, Doodle Smart flexibly matches more than 50 sensor control devices, providing ultra-long distance networking of 3km, ultra-low power consumption of 5MW and 7*24 hours monitoring and warning.
1)LPWA, Low Power Wide Area Technology, is the fastest growing technology solution in the IoT industry, with a CAGR of 90% and a projected market size of US $24.46 billion by 2024. Its advantages are also very prominent:
Low power consumption: the battery life of the equipment can reach 5-10 years;
Low bandwidth: No cellular network deployment and minimal bandwidth usage;
No-dead-corner information transmission: the vast open distance is 3 ~ 5Km. For the greenhouse with complex content structure, no dead-corner information transmission can be realized through the deployment of patent network.
Large processing capacity: requires less base stations, a base station can access tens of thousands of devices at the same time;
Easy to install: Easy to deploy and low cost, scalable and rapid deployment
2) Agricultural Internet of Things Intelligent Hardware:Based on Powered by Tuya intelligent hardware equipment SKUS, intelligent hardware including soil pH monitor, water fertilizer machine, irrigation controller, plant growth lamp, environment monitor, carbon dioxide monitor and so on can be provided for intelligent greenhouse scene. The detailed list is as follows:
(3) Greenhouse Zhilian, one App is enough
Based on more than 310,000 types of Powered by TUYA equipment SKUS, it provides services in more than 220 countries and regions, radiating over 100,000 online and offline sales channels around the world, helping customers in the greenhouse industry to make breakthroughs in the core technologies of greenhouses. Greenhouses “machines to replace human”, “computer replace the human brain” transformation, improve the level of intelligence and business network of agricultural production, speed up the information service, reduce the cost of application for farmers to use, affordable, with good personalized information service, greatly improve the efficiency of greenhouse production, efficiency and benefit.
At the same time, the multi-terminal SDK of Android, iOS and small program provided by Doodle, as well as SDK of each category expansion and function expansion, can help customers in greenhouse industry to quickly realize farmland management APP and small program development. You can also quickly build your own SaaS applications for the greenhouse industry based on the Open API and industry capability components of the cloud development platform, coupled with the Powered by Tuya smart hardware ecosystem.
Intelligent hardware + management background + APP, realize the greenhouse intelligent and linkage control.
