Agricultural Internet of Things (IoT) technology is a network of monitoring, monitoring, gathering and analyzing information of soil, water and fertilizer, air temperature and humidity in agricultural production environment through a variety of sensing devices such as information acquisition and transmission to realize automation, intelligence and remote control network technology. With the development of IoT technology in traditional agriculture, precise control over agricultural production has been achieved. Remote regulation has made traditional agriculture more "smart." First, the Internet of Things technology in smart agriculture in the key technologies 1.WiFi technology WiFi technology is the technology that allows electronic devices to connect to the LAN. Can support a lot of electronic products, wireless Internet access, the implementation of wireless network transmission. WiFi technology undertakes the task of information perception in intelligent agricultural applications. The environment and other information collected by the sensors in information sensing needs the support of WiFi technology, and the collected information needs to be exchanged and transmitted to the application analysis level WiFi technology makes it efficient and safe. It can be said that WiFi technology is the basis for the application of IOT technology in smart agriculture. Without the support of WiFi technology, IOT technology can not play its due role. 2.RFID technology RFID technology that radio frequency identification, is a kind of communication technology. Its main principle is to use the radio signal to perceive the monitoring target and record the data. It mainly consists of three major components: transponders, readers and application software systems. The operation process in the Internet of Things technology is: after the reader detects the signal, the radio frequency signal is emitted by the antenna at the corresponding frequency, and the application software system performs the information processing after receiving the frequency signal of the information, and the internal chip of the device stores the The information is transmitted out, the reader receives the frequency signal again to carry on the data analysis processing, transmits to the background operating system, carries on the control to the information data. 3 sensor network technology Sensing network technology is in the need for information collection and transmission of the region will be integrated sensors, data processing units and communication components of the random distribution, the formation of the network structure associated with each other, that is, sensing network. The number of nodes is relatively large, adaptable in a complex and ever-changing environment. Although its information transmission capability is relatively limited and there is a certain degree of interference between signals, the impact is small due to the small amount of data transmitted by individual node components. Because nodes are dense and distributed randomly, they need to have a certain degree of energy storage function. Sensing network technology can be said that the core of IoT technology plays an important role in the interconnection of things and information exchange and transmission. Second, the main application of Internet of Things technology in smart agriculture 1. IoT in agricultural production applications The application of Internet of Things technology in agricultural production has solved the problem of "getting a good species," and has been widely used in fields such as greenhouse cultivation, livestock and poultry aquaculture, and agricultural machinery networking. First, to monitor the changes in the environment to achieve intelligent management, through the wireless or wired sensor nodes, solar power systems, information acquisition equipment, transmission systems to obtain information on the growth of plant environment monitoring environment dynamic changes. Monitoring soil moisture, soil temperature, air temperature, air humidity, light intensity, plant nutrient content and other parameters. According to the above feedback of all kinds of parameters, the agricultural park will be automatically irrigated, cooled automatically, automatically rolled, automatic liquid fertilizer fertilization, automatic spraying and other automatic control. Commercial lighting originates from the birth of public commercial spaces, creating lighting systems for commercial use in order to serve the needs of commercial lighting.Application scenarios include entertainment venues, bars, cafes, museums, cinemas, stages, hotels, hotels, conference rooms, exhibitions Led Floodlight,Led Linear Light,Led High Bay,Commercial Led Light Guangzhou ZG Scaffolding.co.Ltd , https://www.zgscaffolding.com
