Electronic vehicle license system

Abstract

The invention provides an electronic vehicle license system. The electronic vehicle license system adopts a single chip microcomputer as a processing core, is used with a metal vehicle license together to overcome multiple disadvantages of an ordinary vehicle license and provides a novel electronic vehicle license with functions of theftproofness, forgery prevention, emergency call, remote control and the like. The electronic vehicle license system is realized by the technical schemes that: the whole system consists of an electronic vehicle license and handhold equipment. A PC transfers a cipher text after encryption into a corresponding radiofrequency storage module through a radiofrequency module, the radiofrequency module needs to modulate information and launches the information in a mode of electromagnetic wave signals, the handhold equipment receives the signals and coverts the signals to the original information through demodulation, and a handhold MCU decryption LCD displays vehicle information. An electronic vehicle license display consists of a lattice type display, a drive circuit and a control chip, and the information is encrypted in an electronic vehicle license controller and is decrypted and displayed in the electronic vehicle license display. The electronic vehicle license has a theftproof function. If a vehicle license is stolen, the control chip of the electronic vehicle license display enables a main chip in the electronic vehicle license display to be burnt.

Description

technical field [0001] This electronic license plate system is used for identification of urban vehicles, mainly to combat all kinds of stolen cars, cars with fake license plates, and over-limit cars. Background technique [0002] In recent years, due to the sharp increase in the number of motor vehicles, smuggled cars, stolen cars, and over-limited cars driving on the road have brought many difficulties to the traffic control department. In order to strengthen management and improve efficiency, electronic license plates have emerged as the times require. [0003] In order to ensure the uniqueness of the license plate, many license plates use infrared communication, radio frequency communication or Bluetooth technology. These means of communication are either too short in communication distance, the practical application range is limited, or the price is high, which is not easy to promote. And in terms of the license plate itself, it is easy to lose and damage. Once it is...
