The general application of the agricultural Internet of Things is to form a large number of sensor nodes into a monitoring network, and collect information through various sensors to help farmers find problems in a timely manner and accurately determine the location of problems. The production mode of isolated machinery shifted to the production mode centered on information and software, thus making extensive use of various automated, intelligent, remotely controlled production equipment.
In the greenhouse control system, the temperature sensor , humidity sensor , pH sensor, light sensor, CO2 sensor and other equipment of the Internet of Things system are used to detect the temperature, relative humidity, pH value, light intensity, soil nutrients, CO2 concentration, etc. in the environment The physical quantity parameters are displayed in real time by various instruments or participated in the automatic control as a parameter of automatic control to ensure that the crops have a good and suitable growing environment. The realization of remote control enables technicians to monitor and control the environment of multiple greenhouses in the office. Using wireless networks to measure and obtain the conditions for crop growth can provide a scientific basis for precise greenhouse regulation, and achieve the goals of increasing yield, improving quality, regulating the growth cycle, and increasing economic benefits.
(3) Automatic and intelligent management of agricultural production
For large-scale greenhouse planting, manual management requires a lot of manpower, is labor-consuming and time-consuming, and there are unavoidable manual errors. The Internet of Things system can compare the environmental parameters such as air temperature and humidity , soil moisture, and soil temperature in the greenhouse with preset values, and start relevant equipment to adjust the greenhouse environment when there are significant differences.
The application of the Internet of Things technology has truly realized agricultural production automation and intelligent management, making greenhouse greenhouse planting management intelligent temperature adjustment and fine fertilization, so as to increase production, improve quality, save manpower, reduce manual errors, and improve economic benefits. Objective To achieve efficient and precise management of greenhouse planting.
Collecting soil temperature, humidity, and nutrient content through sensing equipment such as radio frequency identification (RFID), infrared sensors, laser scanners, etc. of the Internet of Things system, and using intelligent analysis and optimization technology to quickly make optimal decisions to meet the crop's Growth needs. When the environmental conditions reach the pre-defined conditions, the automatic control system is turned on to achieve water saving, power saving, labor saving, and more peace of mind.
2. Agricultural video surveillance system
Remotely view the growth of crops, the operating status of various horticultural equipment, and the production situation anytime, anywhere. With this "Clairvoyance", managers can easily monitor and manage job production remotely, which greatly reduces the workload.
3.Mobile remote management system
Mobile phone remote control is another convenient control method for the agricultural Internet of Things control system. Through the mobile phone client, you can remotely view facility environmental data and equipment operation, and analyze data for convenient and flexible management.
After using a mobile phone or computer to log in to the system, farmers can query real-time environmental parameters, historical temperature and humidity curves, historical electromechanical equipment operation records, historical photos and other information in the greenhouse (greenhouse); after logging in the system, they can also query local agricultural policies , Market information, supply and demand information, expert announcements, etc., to achieve targeted comprehensive information services.
The alarm system needs to set the upper and lower limits suitable for the conditions in advance, and the set values can be modified according to the changes in the type of crops, growth cycle and season. When a certain data exceeds the limit, the system immediately sends a warning message to the corresponding farmer, prompting the farmer to take measures in a timely manner.
(Three) highlights- quality traceability system of agricultural products
To solve food safety problems, it is necessary to record the agricultural growth environment, spraying and fertilizing conditions, and pest and disease conditions of agricultural products from various stages. Many people may doubt it, but this is the highlight of the Internet of Things.
Use local network or Internet and other communication technologies to connect sensors, controllers, machines, people and things in new ways to form people-to-things, things-to-things, and realize informationization, remote management control and intelligent The internet. During the storage, transportation, and sales stages, two-dimensional code or RFID radio frequency technology is used to record data at each stage. Through smart tags, people can obtain extended information contained in the object, such as the amount of money on the smart card, and the information contained in the two-dimensional code. URL and name query product status. By tracing the results of the commodities and the inquiry and tracking of the production, sales and other links of the enterprises involved, the supervision department can achieve effective supervision of the safety of agricultural products and related agricultural enterprises, and consumers can rest assured to choose food.
