Compared with the prior art, the utility model discloses can show more more useful vehicle information, and occupation space is few, space utilization is high, the reliability is high, has certain fault -tolerance (the part still can normally read) after damaging, can show different information as required, there are storage and inquiry function, can save and inquire historical detection record of vehicle and dynamic information (for example detection number of times, detect information such as data, vehicle technical state ) at every turn.
Description
Technical field
This utility model belongs to information of vehicles identification field, it particularly relates to compile to a kind of based on QRcode
The information of vehicles identification car-mounted device of code.
Background technology
At present, combination property of motor vehicle measuring station employs information of vehicles identification card and carries out vehicle during detection
The identification of information, this technology is administration section's management to vehicle for convenience, the most also improves motor vehicles comprehensive
The detection efficiency of performance measuring station, is the embodiment of digital management.But, the identification card of actually detected middle use
The information stored is single, only the essential information of vehicle, and amount of storage is little, can not store history detection note
Information in more more useful information, and identification card such as record is one-time write, can not revise, and damages
Afterwards, should not repair, can only change, recycling rate of waterused is low, and this is a kind of non-dynamic management, it is impossible to timely
Solve the multidate information (such as detect number of times, detect the information such as data, vehicle technology state every time) of vehicle.
Therefore, in order to solve the above-mentioned deficiency of prior art, it is badly in need of wanting the most advanced more effective information of vehicles of one
Identify car-mounted device.
Utility model content
For solving the problems referred to above, this utility model provides a kind of information of vehicles identification based on QRcode coding
Car-mounted device, including the display screen being all connected with Embedded Computer On Modules, information of vehicles memory module, entity
Button and supply module；
Described physical button is connected with Embedded Computer On Modules, is used for inputting various operational order and transmitting to embedding
Enter formula computer module；
Described information of vehicles memory module is connected with Embedded Computer On Modules, for storing relevant all kinds of of vehicle
Information, reads and writes for Embedded Computer On Modules；
Described display screen is connected with Embedded Computer On Modules, for showing what Embedded Computer On Modules transmitted
QRcode coding information and the information of other needs displays；
Described supply module is for powering to display screen, Embedded Computer On Modules, information of vehicles memory module；
Described Embedded Computer On Modules, for reading the data in information of vehicles memory module, carries out QRcode
Encode and verify errorless after, by coding information transmit to display screen, simultaneously drive display screen and show that this coding is believed
Breath.
Further, described device is typically placed at shield glass position, it is simple to code reader is scanned.
Further, described information of vehicles memory module uses FLASH memory module.
Compared with prior art, the present invention can show more more useful information of vehicles (can display digit, character,
And the mixed content such as Chinese text), and occupy little space, space availability ratio is high；Reliability is high, has certain
Fault-tolerance (still can normally read after partial destruction)；Easily repair, reusable, can show not as required
Same information；Have storage and query function, can store with enquiring vehicle history detection record and multidate information (such as
Detection number of times, detect the information such as data, vehicle technology state) every time.

Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following example are descriptive
, it not determinate, it is impossible to limit protection domain of the present utility model with this.
As it is shown in figure 1, this utility model provide a kind of based on QRcode coding information of vehicles identification vehicle-mounted
Device, including the display screen being all connected with Embedded Computer On Modules, information of vehicles memory module, physical button
And supply module；
Described physical button is connected with Embedded Computer On Modules, is used for inputting various operational order and transmitting to embedding
Enter formula computer module, such as show, edit, store, the operational order such as deletion；
Described information of vehicles memory module is connected with Embedded Computer On Modules, for storing relevant all kinds of of vehicle
Information, including vehicle essential information, the detection static state such as data, vehicle-state and multidate information, for embedded meter
Calculation machine module is read and write；
Described display screen is connected with Embedded Computer On Modules, for showing what Embedded Computer On Modules transmitted
QRcode coding information and the information of other needs displays；
Described supply module is for powering to display screen, Embedded Computer On Modules, information of vehicles memory module；
Described Embedded Computer On Modules, for reading the data in information of vehicles memory module, carries out QRcode volume
Code and verify errorless after, by coding information transmit to display screen, simultaneously drive display screen and show this coding information.
Described device is typically placed at shield glass position, it is simple to code reader is scanned.
The coding that the coding of described embedded computer system generation and display screen show is QRcode code.Institute
Stating main control chip in Embedded Computer On Modules and use ARM9 series, model is AT91SAM9G35.Described display
Screen uses LCD color LCD screen, and model is JLX500-011-BN；Or employing touch screen, collects input and output
Being integrated, model is DMT48320M035_06WT (Mini DGUS).Described information of vehicles memory module uses
FLASH memory module, model is NandFlash K9F1G08U0D (1G Bit).
Operation principle and the information of vehicles identification process of this device are as follows: first, press physical button or touch screen
In function key, embedded computer system after the instruction of " display information of vehicles identification code ", is adjusted receiving
This car information of storage in an information storage module of picking up the car (includes the letters such as license plate number, Motor Number, vehicle VIN
Breath), through data encoding and verify errorless after, by coding information transmit to display screen, simultaneously drive display
Screen shows this coding information, for evaluator identification information of vehicles.
Compared with prior art, the present invention can show more more useful information of vehicles (can display digit, character,
And the mixed content such as Chinese text), and occupy little space, space availability ratio is high；Reliability is high, has certain
Fault-tolerance (still can normally read after partial destruction)；Easily repair, reusable, can show not as required
Same information；Have storage and query function, can store with enquiring vehicle history detection record and multidate information (such as
