LED advertising information remote renting publishing system and method based on GSM

Abstract

The invention discloses an LED advertising information remote renting publishing system and method based on a GSM. The system comprises a single chip microcomputer master control module, a GSM communication module, an LED driving circuit, an LED dot matrix display screen and a word stock storage chip. The GSM communication module, the LED driving circuit and the word stock storage chip are connected with the single chip microcomputer master control module respectively, and the LED dot matrix display screen is connected with the LED driving circuit. According to the method, after a notice of the GSM communication module is received by the single chip microcomputer master control module, original data of a short message are read, the data are analyzed, advertising text is extracted, the word stock storage chip is searched for character dot matrix information corresponding to the advertising text, the character dot matrix information is sent to the LED driving circuit, and the LED dot matrix display screen is controlled to display the advertising text in a rolling mode. According to the system, the GSM communication module is adopted for achieving remote advertising renting applications, great convenience is brought to advertising requirements of users, multiple pieces of advertising information of the multiple users can be managed, and response is given to the advertising applications of the multiple users at the same time.

Description

technical field [0001] The invention relates to a system for long-distance lease and release of LED advertisement information, in particular to a system and method for remote lease and release of LED advertisement information based on GSM. It belongs to the field of LED advertising information release. Background technique [0002] SMS (Short Message Service) is an application service for sending and receiving text messages between GSM terminals (mobile phones) provided in the GSM (Global System for Mobile Communication) system through the Service Center. The center completes the storage and forwarding functions of information. As a basic service of GSM network, short message service has been paid more and more attention by system operators and system developers, and various applications based on this service are also flourishing. With the GSM network as the wireless data transmission network, a variety of applications with extremely optimistic prospects can be developed, ...

Problems solved by technology

[0007] At present, many companies have launched related products related to LED information release. Related technologies include LED screen refresh and information receiving technology. For example, Taian New Vision has developed a control LED display based on the ARM9 processor S3C2410X and CPLD chips. The application system of the screen, the LED display screen with wireless remote control can receive text information through GSM text messages, but these existing technologies have disadvantages such as high cost, slow screen refresh speed, and single release target

[0008] In addition, similar GSM advertising release products on the market such as figure 1 As shown, most of them do not have the function of responding to multiple advertisements for remote release at the same time, but only release them sequentially through a release center. Users must wait for other mobile phone advertisements to be used up when publishing GSM advertisements. This only achieves the function of remotely releasing updates, and there is no user at the same time. The function of management, the SMS receiving method is as follows: figure 2 As shown, after the MCU responds to the interruption of SMS reception, it immediately reads the content of the SMS according to the index of the SMS, but it takes a lot of processing time to read the content of the SMS. During this period, it will affect the response to the interruption of the SMS advertisement application again Therefore, this kind of GSM advertising release product will have the problem of system resource conflict
