Description

Intelligent broadcasting system of scene Technical Field The invention belongs to the technical field of intelligent broadcasting, and particularly relates to a scene intelligent broadcasting system. Background With the development of the age, more people use free time for travel. The explanation of tour guide can be better let the visitor know history culture, in the tourism explanation scene, common wireless data transmission mode includes technical scheme such as radio broadcast, bluetooth or wiFi, can correspond the selection according to the scene in the practical application, for example the audio transmission of point-to-point selects bluetooth, the data transmission of high bandwidth demand selects wiFi, intercom or select with the mode of radio broadcast. In the occasion that tourists scatter and need fixed-point explanation (tourists at tourist exhibition hall scenic spots), the project party broadcasts the point location through radio beacons, the tourists wear earphone receivers, and when the tourists approach a certain beacon, the audio files pre-stored in the receivers are triggered to be played. The method has the problems of triggering playing due to mutual crosstalk and dislocation among beacons, complexity in content management built in a receiver, large workload for realizing battery management on a plurality of beacons and a larger number of receivers and the like. Meanwhile, when workers or tourists of the tour guide group are led to walk and watch and talk, the tour guide sound is generally transmitted to the earphone of each tourist in a one-to-many Bluetooth or radio broadcasting mode.
