IP network sound post system

Abstract

The invention discloses an IP network sound post system. The IP network sound post system comprises a cloud platform, a plurality of secondary platforms and a plurality of sound posts, the plurality of secondary platforms are connected with the cloud platform through a network; the plurality of sound columns are connected with the secondary platform through network cables, each sound column comprises a control module and a loudspeaker, the control module comprises a TCP / IP protocol analysis and communication module, an MCU main control software decoding module, an audio data decoding module and a power amplification circuit module, and the TCP / IP protocol analysis and communication module is connected with a network cable interface; the MCU main control software decoding module is connected with the TCP / IP protocol analysis and communication module; the audio data decoding module is connected with the MCU main control software decoding module, and the audio data decoding module is alsoconnected with the audio interface; the power amplification circuit module is connected with the audio data decoding module; and the loudspeaker is connected with the power amplification circuit module. The system has the advantages that the transmission distance is long, signals are not distorted, and each sound post can be independently controlled.

Description

technical field [0001] The invention belongs to the technical field of sound columns, and in particular relates to an IP network sound column system. Background technique [0002] The existing broadcasting basically adopts analog transmission and manual management. The system is susceptible to environmental interference, and crosstalk is prone to occur during multi-channel broadcasting. Digital format (MP3) audio files cannot be directly played on the terminal, and cannot be connected to the IP network. The sound quality is poor, the function is single, the installation is complicated, the maintenance is inconvenient, the failure rate is high, and the manageability is poor. Playing equipment (tapes, records, CD players, etc.) and computers storing MP3 files are used as sound sources, and special personnel are required to manage broadcasting content in special locations. Therefore, modern technology cannot be used to effectively manage broadcasting sound sources, let alone re...

Problems solved by technology

[0002] The existing broadcasting basically adopts analog transmission and manual management. The system is susceptible to environmental interference, and crosstalk is prone to occur during multi-channel broadcasting.

Digital format (MP3) audio files cannot be directly played on the terminal, and cannot be connected to the IP network. The sound quality is poor, the function is single, the installation is complicated, the maintenance is inconvenient, the failure rate is high, and the manageability is poor. Playing equipment (tapes, records, CD players, etc.) and computers storing MP3 files are used as sound sources, and special personnel are required to manage broadcasting content in special locations. Therefore, modern technology cannot be used to effectively manage broadcasting sound sources, let alone remote playback control. Conducive to the flexible application of the broadcasting system, resulting in waste of resources
