GPRS and CDMA Wireless LED Information Release System Based on WEB Platform

I. Overview

Since the information input of the conventional LED display can only be performed by directly connecting the data line to the computer, the conventional LED display cannot satisfy the need for real-time release of the remote information, and thus it cannot construct a large-scale networked LED screen information publication. system. The GPRS and CDMA wireless LED information release system developed by Xiamen Yueneng Technology Co., Ltd. based on the WEB platform can effectively solve the problem of remote networking of LED displays. The system is based on GPRS, CDMA wireless network technology and WEB information service technology, provides a common LED communication control interface, and realizes large-scale networking of LED display screens. Whether it is an ordinary text strip screen or a large screen graphic screen, as long as the LED wireless transmission terminal is connected, the limitation of the traditional LED display screen can be immediately broken, and it becomes a wireless LED display screen information display capable of large-scale networking. The wireless LED information display is a new type of information media. Once it is available, it is accepted by a wide range of social organizations. Its “mobile” display and networking information are more respected by the advertising industry and become a new type of advertising media. . Regardless of where the LED display is located and the number of LED displays, the main control center that logs into the system through the Internet can accurately and instantly publish information to one or more or all of the designated LED displays. 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 to release information, and it exerts great effects in expanding the application of LED display screens.

Second, the characteristics of wireless LED information release system

1. Large scale of networking: The contents of traditional LED display screens are sent by computers through serial data lines, and the number of display screens is limited on the scale. The wireless LED display information release system sends information through GPRS and CDMA wireless networks, using the TCP/IP network transmission protocol, and the number of terminal networks is not limited.

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, the information can only be updated through the computer. Wireless LED display can receive the information issued by the information center at any time.

3, no distance limit: the traditional electronic display can only be used within a short distance, generally only tens of meters, wireless LED display in the country, as long as the wireless GPRS, CDMA network coverage can be used anywhere, from the distance And location restrictions.

4. Easy installation and maintenance: Because there is no need to lay fiber optic cables or communication cables, the installation position of wireless LED display screens is easy to choose. The product adopts a modular design for easy maintenance and overhaul.

5, based on WEB's release management system, the release of information without the need to control the center, as long as the Internet login system can release information anytime, anywhere.

Third, wireless LED display information release system design principles

1. Advanced: Take advantage of advanced technologies such as computer internet, mobile wireless communication system, and LED display control, and design a domestic advanced wireless LED display information release system. The use of current advanced system software platforms and terminal equipment not only supports the need for wireless LED display information networking, but also supports the specific business needs of related industries.

2. Reliability: Due to the particularity of the use environment of the wireless LED display information release system, it must be ensured that the system work is 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 software platform such as the operating system, database, and the central service system; second, the reliability of the wireless LED display terminal. Sexuality mainly means that 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 of wireless network communication environment has its own characteristics of complexity, the system communication mechanism must ensure that the data transmission is efficient and reliable.

3. Extensibility: The system must have good scalability. When the number of terminals increases, the user area is expanded, and system functions increase, it can be upgraded smoothly and protect investment. At present, the wireless LED display information release system can support the existing various types of wireless communication access, GPRS communication system, CDMA communication system, and realizes the parallel operation of these systems. In the future, the corresponding communication interface protocol can be developed and installed. Enable access to other future communications systems.

4. Practicality: The operation of the entire system is based on convenience, simplicity, and high efficiency. It not only fully reflects the characteristics of rapid response, but also facilitates the handling and release of information by the operators, facilitating the management to understand the statistics in a timely manner.

5. Confidentiality: Strict rights management is applied to the management of the system. Only the keys with certain permissions can access, monitor and implement the corresponding management and control operations to ensure the system is safe and reliable.
