1. Industry background
As a large agricultural country, China has developed agricultural technology rapidly in recent decades, and there are many greenhouses in the country. The plants planted in the greenhouse usually have more stringent requirements on the growth environment: temperature, humidity, carbon dioxide concentration and other indicators need to be maintained within a stable range. In the early greenhouses, the temperature, soil humidity, and light intensity were observed through manual observation and recording. The monitoring mainly relied on personnel to stay behind, and the land drought relied on artificial watering. With the increasing number of greenhouses, it becomes more and more difficult to rely on manual management.
In recent years, the rapid development of the Internet of Things technology and the level of agricultural automation. The intelligent greenhouse automatic monitoring system based on "Internet +" can realize real-time adjustment of greenhouse temperature and irrigation time according to environmental data. It has the characteristics of high control accuracy, stable and reliable work , Reducing the labor cost of the greenhouse. The IoT and intelligentization of greenhouses will become the future development trend of agriculture.
Second, the solution
In view of the development needs of intensive, high-yield, efficient, ecological, and safe agricultural greenhouses, based on the networking experience accumulated in the field of Internet of Things for many years, some people have proposed online collection of soil and environmental parameters, intelligent networking, wireless transmission, data processing, and early warning Agricultural greenhouse IoT solution with integrated functions of information release, decision support, and automatic control. Growers can grasp the planting environment information in real time through mobile phones, PDAs, computers and other information terminals, obtain abnormal alarm information and environmental warning information in time, and adjust the control equipment in real time according to the environmental monitoring results to achieve scientific planting and management of agricultural greenhouses. Achieve the goals of energy saving and consumption reduction, green environmental protection, and increase production and income.
Three, program advantages
1. LoRa wireless networking
The wireless connection between the gateway and various sensors is through LoRa technology. On the one hand, it can solve the wiring problem. On the other hand, the use of LoRa low power consumption technology can greatly reduce the power consumption of the sensor node. A dry battery can be used for 2 to 3 years.
2. Configuration display
The platform can display real-time air temperature, air humidity, carbon dioxide concentration, light intensity, soil temperature, soil humidity, soil conductivity and other data in the greenhouse, and comprehensively and intuitively present the agricultural data and changes of each monitoring station.
3. Reverse control
According to the collected temperature and humidity, light intensity, carbon dioxide concentration and other parameter thresholds, reverse control of fans, water curtains, solenoid valves and other equipment in agricultural greenhouses through network communication equipment and IO control equipment completes the closed-loop control of smart agriculture.
4. Security and intelligent alarm
The platform sets alarm rules, and can perform data alarm according to the set alarm value. Once the parameters such as temperature, humidity and CO2 concentration in the greenhouse exceed the set threshold, the alarm information can be pushed to the mobile phone through the cloud.
The platform also supports video monitoring functions, which can view the monitoring pictures in the greenhouse and surrounding area in real time.
4. Industry Application
At present, China is in a critical period of transition from traditional agriculture to smart agriculture. The intelligent greenhouse under the thinking of the Internet of Things, as a bursting point in modern agriculture, can drive the development of rural agriculture, promote the comprehensive and deep integration of information technology and agricultural and rural areas, and develop wisdom agriculture. Therefore, through science and technology demonstration, vigorously promoting and applying the Internet of Things technology such as the greenhouse monitoring system is of great significance for the early realization of agricultural modernization. This solution will facilitate the intelligent management of greenhouses such as vegetable cultivation, strawberry cultivation, and flower cultivation.
