Abstract
A distributed in-vehicle noise grading detection and prompt device consists of a distributed signal acquisition module, a data processing module, a display and alarm module and a wireless transceiving module. The numbers of voice operated switches and single chips at a passenger zone are determined according to the specific type of an automobile. Each single chip is connected with three voice operated switches; and threshold values of different levels are set for the three voice operated switches so as to realize grading detection for signals. Wireless transmitters connected with the single chips at the passenger zone do not interfere with one another; and the single chip at a driving zone is connected with a wireless receiver for receiving the wireless signals of the passenger zone. The display and alarm module performs real-time prompt and alarm according to different noise conditions. The distributed in-vehicle noise grading detection and prompt device can help a driver to monitor and know the noise conditions of each zone in the vehicle in real time so as to effectively reduce the in-vehicle noise pollution, improve the riding comfort of a carriage, and protect the physical and psychological health of drivers and passengers and the safety performance of the carriage in running.
