Directional sound advertisement system based on network control and network control method

Abstract

The invention discloses a directional sound advertisement system based on network control, comprising a directional sound working unit, a network access module and a server; each directional sound working unit is connected with the internet by the network access module, and fixed IP address is obtained; the server is accessed to the internet, and network control of the directional sound working unit is realized, the system is further improved, the system adopts a multi-level server framework, the server at the lower layer is connected with the server at the upper layer by a switchboard and iscontrolled by the server at the upper layer, the server at the lowest layer is accessed to the internet and is connected to a plurality of the directional sound working units; in the invention, network control technology is fully utilized, the control range is large, the controlled working units are more, so as to effectively overcome the disadvantages that the control coverage range is small, controllable playing devices are less, the function is single and the content switching speed is slow in the traditional mode; in addition, the invention further discloses a network control method of the directional sound advertisement system.

Description

technical field [0001] The invention relates to sound directional communication technology, in particular to a network-based directional sound advertisement system and a network control method for the directional sound advertisement system. Background technique [0002] The existing outdoor advertising audio playback systems all adopt an omnidirectional audio playback method. In practice, there are the following problems: [0003] 1. The directivity of the sound is poor. Some advertising systems are prone to noise disturbance due to improper control, disturbing the normal life of nearby residents, not only failing to achieve the purpose of advertising, but also causing disgust from the audience; [0004] 2. The controllability of the network is not strong. Usually such advertisements are played through one control device to operate several audio playback devices. The control coverage is small, the controllable playback devices are few, the function is single, and the content...
