" Agricultural Internet of Things " is the specific application of Internet of Things technology in agricultural production , operation, management and services. According to the technical framework of the Internet of Things , the agricultural Internet of Things still implements the application of agriculture through the "sense-transmit-application" approach. "Perception" is the use of various types of sensors , such as temperature and humidity sensors , light intensity sensors , pH sensors, CO2 sensors and other equipment, to collect real-time temperature in the environment of field planting, facility horticulture, livestock and poultry farming , aquaculture and agricultural product transportation. , Humidity, PH value, light intensity, soil nutrients, CO2 concentration and other physical quantity parameter information; "Transmission" is to establish data transmission and conversion methods, through local wireless networks, the Internet, mobile communication networks and other various communication networks to interactively transfer and achieve Effective transmission of agricultural production environmental information; "application" is the fusion and processing of a large amount of acquired agricultural information, enabling technicians to monitor and control and intelligently manage the environment of multiple greenhouses to ensure a good and suitable growth environment for crops To achieve the purpose of increasing production, improving quality, regulating the growth cycle, and improving economic benefits, and then achieve the goals of intensive agricultural production, high yield, high quality, high efficiency, ecology and safety.

Vegetable greenhouses and greenhouses are mainly used in seasons that are not suitable for vegetable growth. They simulate the natural conditions of vegetable growth and provide an environment where vegetables are suitable for growth. The realization of this environment cannot be based on feelings. It is necessary to introduce the agricultural Internet of Things greenhouse environmental monitoring technology to solve vegetable growth The controllability of the environment achieves the purpose of improving the benefits of vegetable production.

I. Construction of vegetable greenhouse control system :

A complete vegetable greenhouse automatic control system includes data collection, data transmission, data analysis, and production operating systems. Each part has different functions in vegetable production. These functions are combined to complete the entire process of vegetable production.

2. The automatic control system of the IoT environment of the vegetable greenhouse mainly includes the following sub-system parts:

1. Data acquisition system:

The data acquisition system consists of wireless sensors , power supplies, or batteries; the monitoring elements at the site include monitoring elements such as temperature and humidity , CO2 concentration, soil temperature and humidity, and soil nutrients. The data collection system is mainly responsible for the collection and control of data such as light, temperature, humidity, soil moisture content, and video inside the greenhouse.

2. Data transmission system:

The data transmission system consists of data acquisition sensors, including temperature sensors , humidity sensors , light intensity sensors, photosynthetically active radiation sensors, soil temperature and humidity sensors , CO2 sensors, and wind direction sensors. Transmission method: The external network is based on IP network technology and GPRS communication network for transmission; the internal network uses short-range, low-power ZigBee wireless communication technology. In the ZigBee-based wireless transmission mode, the data collected by the sensor is transmitted to the central node through the ZigBee transmission module. At the same time, the control instructions transmitted between the user terminal and the integrated controller are also transmitted to the central node. The sensor platform and control instructions are sent to the business platform of the host computer. The technicians can access the upper computer system business platform through the wired network / wireless network, monitor the sensor parameters of the greenhouse site in real time, and control the relevant equipment on the greenhouse site.

3. Data analysis system:

The data analysis and display part includes computers, software, wireless receiving modules, and alarm systems. Different control schemes are implemented according to different environments, crops, and growing seasons.

4. Field environment control system:

The sub-system includes an irrigation control system that can control drip irrigation and micro-spray systems to achieve remote automatic irrigation. The soil environment monitoring system uses soil moisture sensors and soil moisture sensors to obtain data such as soil moisture and humidity in real time for irrigation. The control system and temperature and humidity control system provide environmental information; the temperature and humidity monitoring system can use high-precision sensors to collect information on the growth environment of crops and set environmental index parameters. When the environmental index exceeds the parameter range, the fan cooling system and plumbing can be automatically started. Heating system, air circulation system, etc. to adjust the ambient temperature and humidity.

The use of the vegetable greenhouse built by the Internet of Things in the agricultural trade industry can provide advanced technologies for effectively controlling the growth environment of vegetables for greenhouse cultivation, so that the vegetables can obtain a suitable growing environment and increase the yield to achieve cross-season vegetable cultivation.
