Vehicle reminding information transmission method based on sound waves

Abstract

The invention discloses a vehicle reminding information transmission method based on sound waves. The method comprises the steps that a transmitting device transmits reminding information; a receivingdevice receives the reminding information; wherein the method that the transmitting device transmits reminding information includes steps of numbering all the reminding information, selecting reminding information through the controller, an information encoder screening out the serial number of the selected reminding information; the modulator performing data conversion and modulates the data into a carrier wave to form a modulated wave; and releasing the modulated wave through the horn to form a horn sound. The method that receiving device receives the reminding information comprises that asound collector collects horn sound; the filter carries out filtering processing on the horn sound; the amplifier amplifies the horn sound subjected to filtering processing, and carrier waves and modulated coded data are separated out through the demodulator; and the information decoder is used for decoding and automatically finding out corresponding reminding information to remind a reminded person. The existing vehicle whistling mode and effect are not affected, operation is easy, and transmitted information is accurate and comprehensive.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a method for transmitting reminder information for vehicles based on sound waves. Background technique [0002] On busy roads, cars go back and forth. There are often some information interactions between vehicles, vehicles and pedestrians or non-motorized vehicles on the road. At present, the most commonly used methods are through the whistle and lights of the vehicle. However, the information that can be conveyed by vehicle horns and lights is very limited and vague. It may represent different meanings in different situations, and it is often misunderstood, ignored or passed to the wrong object. For example, you can use the whistle to inform the vehicle ahead that it is about to overtake, and pay attention to avoiding it, but it cannot deliver more complicated messages such as "your fuel tank cap is not closed", "green light and time to go". While waiting for the traffic ligh...

However, the information that can be conveyed by vehicle horns and lights is very limited and vague. It may represent different meanings in different situations, and it is often misunderstood, ignored or passed to the wrong object.

For example, the horn can be used to inform the vehicle in front that it is about to overtake, and pay attention to avoiding it, but it cannot convey more complicated information such as "your fuel tank cap is not closed", "it's time to go when the green light is on", etc.

When waiting for a traffic light, it is easy to ignore the siren warning of other vehicles if the driver is looking at his phone or paying attention to other things

Various reasons have led to the continuous honking of vehicles on the road, causing serious noise pollution, which will also affect the mood of vehicle drivers, and more patients with "road rage" will appear
