I. Overview
Since the information input of traditional LED display screens can only be carried out by directly connecting to the computer through a data cable, traditional LED display screens cannot meet the needs of remote information real-time release, and thus cannot build a large-scale networked LED screen information release system.
The LED information release system developed by Xiamen Lingqi Communication Co., Ltd. can effectively solve the problem of remote networking of LED display screens. The system is based on GPRS wireless network technology, provides a universal LED communication control interface, and realizes large-scale networking of LED display screens.
Whether it is an ordinary text bar screen or a large-screen graphic screen, as long as it is connected to the LED wireless transmission terminal, it can immediately break the limitations of traditional LED display screens and become a wireless LED display screen information display screen that can be networked on a large scale.
Wireless LED information display screen is a new information media. Once it is launched, it will be accepted by a wide range of social groups. Its "mobile" display and networked information release features are more respected by the advertising industry and become a new advertising media.
No matter where the LED display screen is placed or how many LED display screens there are, the system's main control center can accurately and instantly release information to a specified one, multiple or all LED display screens.
The wireless LED display information release system can greatly enhance the flexibility and real-time performance of the LED display as an information display carrier, and play a great role in expanding the application of LED display.
II. Features of the wireless LED display information release system:
(1) Large network scale: The content of the traditional LED display is sent by the computer through the serial port data cable, and the number of display screens is limited in scale. The wireless LED display information release system sends information through the GPRS wireless network and adopts the TCP/IP network transmission protocol. The number of terminals connected to the network is unlimited.
(2) Real-time information release: The traditional LED display can only display the information stored in the controller in a fixed manner. If new information needs to be released, it can only be updated through the computer online. The wireless LED display can receive information sent by the information center at any time.
(3) Not limited by distance: Traditional electronic display screens can only be used within a short distance, generally only tens of meters. Wireless LED display screens can be used throughout the country as long as the wireless GPRS network is covered, without being restricted by distance and location.
(4) Convenient installation and maintenance: Since there is no need to lay optical cables or communication cables, the installation location of the wireless LED display screen is easy to choose. The product adopts a modular design, which is easy to maintain and repair.
III. Design principles of wireless LED display information release system
1. Advancedness: Make full use of advanced technologies such as computer Internet, mobile wireless communication system, LED display control, etc. to design a domestically advanced wireless LED display information release system. The current advanced system software platform and terminal equipment can not only support the needs of wireless LED display information networking release, but also support the specific business needs of various related industries.
2. Reliability: Due to the particularity of the use environment of the wireless LED display information release system, the system must be relatively stable and reliable. The reliability of this system is mainly reflected in three aspects: First, the reliability of the central system, including the reliability of the hardware system, the reliability of the operating system, database, central service system and other software platforms; second, the reliability of the wireless LED display terminal, which mainly refers to the wireless LED display terminal can work stably and reliably, and the hardware failure rate is low. Third, the communication mechanism is reliable, because the use environment of wireless network communication has its own complex characteristics, and the system communication mechanism must ensure efficient and reliable data transmission.
3. Scalability: The system must have good scalability. When the number of terminals increases, the user range expands, and the system functions increase, it can be upgraded smoothly to protect the investment. At present, the wireless LED display information release system can support various existing wireless communication access, GSM communication system, GPRS communication system, CDMA communication system, and realize the grid connection operation of these systems. In the future, the access of other future communication systems can be realized by developing and installing the corresponding communication interface protocol.
4. Practicality: The operation of the entire system is convenient, simple and efficient. It not only fully reflects the characteristics of rapid response, but also facilitates operators to process and release information, and facilitates the management to understand various statistical information in a timely manner.
5. Confidentiality: Strict authority management is implemented for the management of the system. Only keys with certain authority can access, monitor, and implement corresponding management and control operations to ensure the safety and reliability of the system.
IV. Main functions of the wireless LED display information release system:
1. The system supports a maximum of more than 10,000 wireless LED display screens;
2. Communication system support: GPRS communication mode, short message communication mode;
3. The system software adopts B/S structure;
4. Support LED display device information management function;
5. Support real-time and scheduled sending of text messages;
6. Add, delete and edit functions of published information;
7. Define different operation users with different operation permissions to achieve hierarchical user management;
V. Application of wireless LED display information release system
As a new information release carrier, the wireless LED display information release system has a broad market and use, and can be widely used in government, commerce, transportation, catering, construction, tourism, sports, transportation and other industries and departments.
Residential buildings: Install wireless LED display screens at the entrances of residential areas, buildings, and courtyards as community information bulletin boards, which are convenient for property and residents to publish property notices, public welfare information, community announcements, meteorological information, safety knowledge, traffic tips, community information, etc., which is conducive to the integration and dissemination of community information, purify the community environment, and enhance the community image;
Government departments: Install wireless LED display screens in the service halls of government departments as government notice boards to publish government policies, public notices, public opinion surveys, emergency notices, warning tips, meteorological information, and legal publicity; wireless LED display screens can become standard terminals for information release and warning systems in meteorological, safety, transportation, water conservancy, fire protection, civil affairs, public security, urban management and other industry departments.
Stores and supermarkets: Install wireless LED displays at store entrances, supermarket entrances, halls, and shelves to publish shopping guides, supply and demand information, price trends, promotions and discounts, new product introductions, merchant recommendations, customer greetings, etc.
It is a window for merchants to guide customers through media and information dissemination, which helps to attract consumers and promote the dissemination of merchant information.
Transportation stations: Install wireless LED displays in station waiting rooms, toll booths, and platforms as electronic bulletin boards to publish bus information, weather forecasts, various advertisements, instant news, traffic conditions, ticketing conditions, temporary notices, etc.;
