With the development of rural economy and society, information plays an increasingly important role in the agricultural economy, and its status is increasingly important. TV has spread to millions of households and computer networks are gradually entering the farm. However, many farmers do not know how to obtain information on the use of agricultural wealth in the vast ocean of information. Meteorological and agricultural multimedia display screens pass useful information that has been screened to farmers, allowing more farmers to gain access to useful agricultural information, and inspire and guide farmers to actively seek out more valuable information. Therefore, the author constructed a meteorological and agricultural multimedia display system in order to provide farmers with a way to obtain agricultural information and popular science knowledge.
Meteorological and agricultural multimedia display systems consist of management servers, file servers, live video servers, weather data servers, small weather stations, user computers, Internet networks, and multimedia displays. The meteorological and agricultural multimedia display system is the result of scientific and technological progress, thanks to the popularity of the Internet and the increase of network bandwidth. The management server is based on the B/S architecture. Staff (system administrators, provincial meteorological bureau staff, county weather bureau staff, and township information personnel) enter the URL, user name, and password of the management server on any networked computer. You can log in to the server and perform various operations. Such as adding and deleting users, adding and deleting meteorological multimedia displays, uploading video files, reviewing video files, modifying parameters of meteorological multimedia displays, sending text messages, video files, selecting live channels, etc. to designated meteorological multimedia displays. After uploading, the user-uploaded video is stored in the file server. The meteorological multimedia display downloads the required video and pictures from the file server according to the program list issued by the management server. The video broadcast server distributes the self-operated or retransmitted video programs to the corresponding multimedia display screens according to the settings of the control server. The management server regularly obtains weather forecast, warning information, and data of each six-element weather station from the weather data server, and then distributes it to the corresponding meteorological multimedia display screen. The multimedia display screen is beautifully displayed and has rich content. It can effectively improve the delivery surface of meteorological and agricultural information, and is suitable for occasions where people's traffic is arranged in government agencies and enterprises. The meteorological and agricultural multimedia display shall display the real-time meteorological information collected by six nearby meteorological stations; display weather forecast, meteorological warning information, and other government agencies’ early warning information, notices, etc.; broadcast home-made broadcast weather channels, agricultural channels, central government, etc. TV show. The user can operate on any computer that can access the Internet without the need to install special software in advance, as long as there is a computer that can access the Internet, the client zero maintenance. And the expansion of the system is very easy, as long as the Internet, and then the system administrator can assign a user name and password. The programming language of the server can use Java. The advantages of the server using Java are high execution efficiency, low consumption of resources, stable performance, and easy expansion. Database can choose SQLserver, SQL is an open source database management software, stable, less loopholes, you can customize. The server adopts WindowsServer2008, a 64-bit operating system, with stable performance and high speed. The live video server connects to the live broadcast server through P2P. The live broadcast server is placed on the intranet and is isolated from the external network through the firewall. This ensures the security of the live broadcast server and avoids attacks. The live broadcast server converts the television signal into streaming media through video live streaming software and distributes it to the multimedia display. The file server uses the FTP protocol. FTP is the most widely used file transfer protocol. It is safe and reliable. Web server uses IIS system. Through the server software, you can add and delete modified terminals, send text messages to the terminal, modify weather forecast information, upload videos, modify live channels, and other functions. You can also remotely close, open, and restart the terminal.
With the development of rural economy and the improvement of the living standards of farmers, the demand for meteorological information, especially severe weather information, has increased dramatically in agriculture, rural areas, and farmers. However, the meteorological information dissemination methods for rural areas and farmers have remained single, and to a large extent The development of rural meteorological disaster prevention and reduction work, as well as the application of artificial climate room. The construction and installation of a meteorological and agricultural multimedia display system is an important way to strengthen regional meteorological disaster prevention and reduction infrastructure construction, effectively improve meteorological disaster early warning capabilities, and help farmers acquire agricultural information and agricultural science knowledge. The meteorological and agricultural multimedia display system is an important part of completely solving the problem of sending meteorological and agricultural information to farmers, and together with the smart wireless broadcasting system, it can completely solve the “last kilometer problem†of meteorology, policy, and agricultural knowledge issued to rural areas. To improve the farmers' ability to prevent and mitigate disasters, bring about huge agricultural economic and social benefits.
