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
This electronic vehicle license plate system is to be used for the city vehicle identification, mainly hits various robbers and robs car, fake-licensed car, wagon loaded with out-of-gouge goods.
Background technology
In recent years, because motor vehicle number increases sharply, walk private car, steal and rob car, wagon loaded with out-of-gouge goods and set out on a journey to travel and bring a lot of difficulties for traffic control department.Raise the efficiency for strengthening management, electronic license plate also just arises at the historic moment.
In order to guarantee the uniqueness of car plate, a lot of car plates all adopt infrared communication, radio communication or Bluetooth technology.These means of communication or communication distance are too near, and practical ranges is restricted, or price is higher, are not easy to promote.And car plate own aspect, lose easily, damage.In case lose or damage and can only just can make up by miscellaneous formality, perhaps when traffic accident occurring, if the troublemaker uses false car plate, the masses just can't correctly report on every side.The electronic license plate that has is to use charactron to show license plate number.The numerical portion of this car plate is variable, but Chinese character part is fixed.Commonality is relatively poor.In addition, existing electronic vehicle license plate system is to use powered battery basically, and the battery access times are limited, and also has memory, uses inconvenient.
Summary of the invention
The electronic license plate control system is power resources with the button cell, and its function system is made up of electronic license plate main control module, electronic license plate display module, hand-held read module three parts.
It is core that main control module is selected intelligent High Accuracy Control chip micro controller system for use, coordinates other each modules and works normally.
The electronic license plate main control module comprises: MCU module, LED display module, memory module, Receiver Module, program download interface.
The effect of MCU module is that functions such as the demonstration of control electronic license plate, storage, radiofrequency signal processing are the cores of system; MCU accesses the information that is stored in the memory device come according to the instruction of the radiofrequency signal that receives, demonstrates on the LED display module, and the inspector can go up the information that the information that shows and metal car plate show according to LED and compare, and differentiates the identity of vehicle; MCU adopts the MSP430 micro controller system of low-power consumption, at ordinary times LED is in dormant state, wakes LED up and show when needs show.MCU adopts and blows the safety fuse cutout technology, and program Solidification can not be read in MCU inside, and the program of preventing is read, and the MCU device adopts the tamper technology, in case dismantle direct defective chip.
The LED display module comprises: LED dot matrix, driving circuit; By MCU control led module content displayed.
Memory module: mainly be the essential information that is used for registration of vehicle, as model color of the number-plate number, vehicle etc.
Receiver Module: adopt the master control of NRF905, receive the information of outside handheld device by NRF905 as the transmitting-receiving radio-frequency information,
Program download interface: adopt JTAG or SBL mode.
Accompanying drawing 1 is the writing station scheme drawing
Accompanying drawing 2 is hand-held reading device scheme drawing
Embodiment
1. the msp430f1612 micro controller system in the electronic license plate is connected with computer by RS232 or download line, and the computer expert crosses software programming number information is write license board information in the mode of encrypting to micro controller system, and MSP430f1612 is made as low-power consumption mode, wake-up waiting.
When traffic control personnel procuratorial work when the activator button of portable equipment is pressed, signal is sent to the master controller msp430f1612 of electronic license plate with NRF905 and the common radio-frequency communication module that constitutes of antenna, the MSP430f1612 that activates wherein makes it enter activity pattern rapidly, light a matrix LED and allow the time remaining 20S that shows, car plate also sends to portable equipment with license board information simultaneously.
3. radio-frequency module carries out certain processing to this information, operation wherein is exactly the modulation to this information, information is modulated into certain electromagnetic wave signal and launches, hand-held radio-frequency communication module receives this electromagnetic wave signal, through demodulation process, electromagnetic wave signal is gone back to into original () signal and passes to msp430169, and msp430169 passes to liquid crystal LCD128645zk again and demonstrates information of vehicles through deciphering.
4. portable equipment is presented at the information that receives from electronic license plate on the liquid crystal LCD128645zk after deciphering, by the number-plate number of relatively LED dot matrix demonstration and the number of metal car plate, determine the true and false of metal car plate or electronic license plate with the number-plate number that shows on the Liquid Crystal Display (LCD) and the metal car plate similarities and differences, portable equipment allows its demonstration " false license plates " to electronic license plate transmission information if comparative result is inconsistent.
5. running into criminal hijack in emergency circumstances, it is that the interruption that MCU enters the priority maximum allows electronic license plate show help information that the car owner can press the flash appeal button, reports to the police in the forces around the prompting.
