A Vehicle Internet of Things System Using a New Generation of Acoustic Communication Technology

Abstract

The invention provides a vehicle Internet of things system applying new-generation sound wave communication technology, which comprises a vehicle and a management system. The management system comprises a vehicle management device and a vehicle limiting device. Communication information is modulated in vehicle sound waves, when the vehicle sound waves are detected by a monitoring device, the sound waves are demodulated through a demodulation module, the communication information sent by the vehicle can be acquired, the communication information is processed through a preset step, whether to meet a preset condition is judged according to a processing result, and if the preset condition is met, the vehicle management device let the vehicle go or stops the vehicle through control on the vehicle limiting device. Through the above mode, by using sound wave communication between a vehicle horn and the vehicle management device, the vehicle is managed.

Description

technical field [0001] The invention relates to the field of new generation information technology, in particular to sound wave communication technology, Internet of Things technology and vehicle management technology. Background technique [0002] Existing vehicle management systems, such as parking lot vehicle management systems, usually pass when entering the field, the car owner presses the buttons on the gates and landing bars to get the IC card, and the gates and landing bars are opened to let the vehicle enter the field. , The management personnel swipe the IC card to check the parking fee. After collecting the parking fee, the management personnel open the gate and the landing bar, and let the vehicle leave. [0003] In a more advanced management system, Bluetooth sensors are installed at the entrance and exit of the parking lot, and corresponding Bluetooth devices are also installed on the vehicle. Through the Bluetooth protocol, the vehicle information is sent to t...

AI Technical Summary

Problems solved by technology

[0006] 1. The IC card access method is inefficient for vehicle management, and the IC card is easy to lose;

[0007] 2. The management system adopts the bluetooth induction method, and the vehicle needs to be specially equipped with a bluetooth device, and the vehicle that is not equipped with a bluetooth device or the bluetooth device is lost cannot be managed;

[0008] 3. Camera shooting and image recognition are used to manage vehicles, and there is a problem that the accuracy of recognition needs to be improved
