Problems solved by technology

[0002] The traditional campus intelligent broadcasting system is connected in a wired way, which requires the laying of a dedicated audio line. This line transmits mostly analog signals, which are easily disturbed by noise, and the wired connection is very important for system maintenance and maintenance. Expansion is very inconvenient, and the function of the line cannot be changed through a simple upgrade of the management equipment

Abstract

The invention discloses a campus intelligence broadcasting system and a working method thereof based on a WLAN. The campus intelligence broadcasting system comprises a voice broadcasting station which is provided with a master control server and multiple campus broadcasting transmission nodes distributed in a campus, wherein the voice broadcasting station is used for collecting multiple campus everyday use analog audio signals, the master control server stores the multiple analog audio signals and converts the multiple analog audio signals to corresponding digital audio signals, and the digital audio signals are wirelessly sent through a WIFI module; each campus broadcasting transmission node comprises a WIFI wireless loudspeaker box, and the WIFI wireless loudspeaker box is applied to receiving the digital audio signals to conduct broadcasting. By means of the campus intelligence broadcasting system and the working method thereof based on the WLAN, a current situation that a traditional wired campus intelligence broadcasting system is still adopted by most of campuses is solved; meanwhile, the spread of the broadcasting information is changed to the spread of digital signals, the noise jamming in a communication process is effectively avoided, the wireless campus broadcasting is achieved, the working efficiency of the broadcasting system is improved, the electric energy can be saved, the consumption is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a campus intelligent broadcasting system, in particular to a WLAN-based campus intelligent broadcasting system and a working method thereof. Background technique [0002] The traditional campus intelligent broadcasting system is connected in a wired way, which requires the laying of a dedicated audio line. This line transmits mostly analog signals, which are easily disturbed by noise, and the wired connection is very important for system maintenance and maintenance. Expansion is very inconvenient, and the function of the line cannot be changed through a simple upgrade of the management equipment. With the development of wireless interconnection technology, the application field of WLAN technology is constantly expanding, and it is widely used in medical care, education, mobile office and other fields. The formation of carrier-level WLAN scale can provide WLAN services for various smart devices and mobile terminals. , Provide a...
