Abstract

The invention provides a train broadcasting system. The train broadcasting system comprises a microphone, multiple loudspeakers, multiple noise detection devices and a controller. The microphone is arranged in a cab. The loudspeakers are correspondingly arranged in multiple passenger compartments. The noise detection devices are correspondingly arranged in the passenger compartments, and each noise detection device is used for detecting the volume of background noise in the corresponding passenger compartment. The controller is connected with the microphone, the loudspeakers and the noise detection devices. When broadcasting is needed, the controller controls the output volume of the corresponding loudspeaker to be higher than a first preset value of the volume of the background noise in the corresponding passenger compartment and lower than a second preset value according to the volume, detected by each noise detection device, of the background noise in the corresponding passenger chamber. According to the train broadcasting system, the output volume during broadcasting can be controlled according to the background noise in the passenger compartments.

Description

technical field [0001] The invention relates to a train broadcasting system. Background technique [0002] In the related art, trains such as trains and subways are equipped with control systems. The train control system includes a broadcasting system and an information display system. In the existing broadcasting system, train drivers or flight attendants can only adjust the volume of the broadcasting system based on experience. If the compartment is relatively quiet and the volume is adjusted very high, the passengers will have a bad feeling; if the compartment is noisy and the volume is adjusted very low, the passengers will not be able to hear the content of the broadcast. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, an object of the present invention is to propose a train broadcasting system, when broadcasting is required, the output vo...
