The invention discloses an interaction system and method for car honking information. The system comprises a honking indication module, a speaker drive module, an ultrasonic transmitting unit and an ultrasonic receiving unit, wherein the honking indication module is connected with the speaker drive module, the ultrasonic transmitting unit and the ultrasonic receiving unit. As information to be sent is combined with car honking, in the car honking process, besides making a honking sound which can be recognized by human ears, the system further transmits car information or driver information in an ultrasonic mode, the sound information will not change the original honking sound or be perceived by the human ears, and a specific receiving device can perceive an ultrasonic signal carrying the car information and explain the information; in this way, the environment will not be polluted. The interaction system and method can be used for short-distance information interaction between cars, car information acquisition in public places and the like, and especially applicable to RFID areas, video monitoring limited areas and areas where radio waves are interfered and shielded.
Description
technical field [0001] The invention relates to an automobile information transmission device, in particular to an automobile whistle information interaction system and an interaction method. Background technique [0002] As the main means of transportation for people's daily travel, automobiles play an important role in people's lives. With the advent of the Internet of Everything era, in addition to being a means of transportation, cars also act as carriers of information, delivering information to users and public traffic management departments. [0003] At present, the ways for vehicles to transmit information are mainly based on radio frequency identification technology (RFID), video surveillance technology and radio communication technology. RFID technology is mainly used for the entry and exit of vehicles in public places, communities, and factories, and records, etc., and the dedicated RFID reader reads the RFID tags in the car to obtain car information. Its curren...
