Key points of purchase of two-dimensional bar code scanning gun in DMV

Release Time:2018-03-07

The key points of purchasing the two-dimensional bar code scanning gun of the DMV, which scanning gun is more suitable for scanning the bar code on the motor vehicle certificate, while the bar code scanning gun used by the DMV is generally dedicated, and the ordinary scanning gun cannot be scanned. Because there are many brands and models of bar code scanning guns, users who do not know enough about the performance of the scanning guns will easily choose the wrong scanning guns. Before choosing the right barcode scanning gun, we need to understand the following questions:

1

1. What is the code system on the motor vehicle certificate of DMV?

2. What interface does the special barcode scanning gun for DMV need to use?

3. How far is the barcode scanning gun from the barcode of the motor vehicle certificate to be scanned? Is this distance convenient for us to read quickly?

4. Is there any requirement for the working temperature, storage temperature and humidity parameters of the scanning gun in the DMV industry environment?

In addition to the above problems, are there any other requirements for the scanning gun in the DMV industry environment?

Only by understanding the above problems can we accurately select the barcode scanning gun suitable for use by the vehicle tube. Now let's take a look at the hardware setting requirements of the DMV for the barcode scanning gun, which are sorted out as follows:

Support code system: QR code (must support),Data Matrix code, PDF417,Maxicode code, RSS code and general one-dimensional bar code

Support interface: must include TTL level RS232 (including USB or other interface analog conversion serial port)

Scan angle: offset angle: ± 40 ° or less; tilt angle: ± 40 ° or less

Shake resistance: 10 cm/s or higher

Noise immunity: 10-100kHz maximum 100mV or higher between two peaks

Operating temperature: 0 ℃ to 50 ℃ or wider range

Storage temperature:-40 ℃ -70 ℃ or wider range

Humidity: 0-95% or wider without condensation

Ambient light: 100,000 Lux or higher

Other requirements: 15mil resolution QR code recognition distance of up to 100mm or more; Different code systems should be automatically recognized without manual intervention; Additional power supply should not be required when connecting with the computer.

DMV dedicated two-dimensional bar code scanning gun recommend:

Honeywell Honeywell 1900 barcode scanning gun is a special scanning gun for DMV certificate. As Honeywell's most advanced two-dimensional image barcode scanner, it strengthens the color imaging function. Its biggest feature is the use of Honeywell ColorFusion™technology and custom sensors optimized for barcode scanning. recommend reasons are as follows:

1. Support a variety of interfaces: including USB, keyboard port, RS232,IBM 46XX(RS485 interface), cable and existing HONEYWELL products 1900 series common.

2. Can read 1D,2D, postal code, OCR characters (supported by specific models), also supports Chinese letter code and DPM barcode. Support image acquisition and image editing function

3. Ergonomic design is better: the compact shape design is suitable for any hand type, the grip is comfortable, and the fatigue of the operator is eliminated.

4. Good durability: IP41 grade, normal use after 1.8 meters vertical drop to the cement ground 50 times, greatly reduce the failure rate by reducing the internal line connection of the equipment, long warranty period, and can disinfect the shell (specific model) and other advantages.

5. Advanced software configuration: TotalFreedom 2.0 can be selected for secondary development, and a variety of software can be directly integrated into the scanner. MasterMind remote management software; Image processing software is used to generate high-quality digital images.
