Design principles of handheld charging machines
1. Ease of use
(1) Ease of use: some comparisons Shortcut keys are set in commonly used places. For example, the handset adopts the authorization mode of swiping the card to read the operator. After the correct authorization, you can press “F2” to re-enter the shortcut without turning off the machine, and there is no need to authorize again.
(2) Automatically connect to the GPRS server when it is turned on, and transmit consumption data in real time (with GPRS function).
(3) Flexible printing of receipts: Various functions of printing receipts are provided, and multiple printings are supported, which can prevent unpredictable situations such as unclear printing.
(4) Friendly operation interface: it conforms to people’s usage habits, the function description is clear, and there are no complicated operation steps.
2. Applicability
(1) Multi-function: You can pre-set consumption amount consumption, input amount consumption, limit consumption 7 consumption modes including secondary consumption can also realize mixed consumption mode.
(2) Flexible use: set parameters to generate parameter files, which can be transferred, copied and other operations; when the hardware needs to be upgraded, our company provides upgrade files for customers to upgrade, and customers only need a U disk to achieve the upgrade hardware.
3. Innovation
(1) Parameter setting and downloading: realize parameter file management; the file is small, and the maximum parameter file is only about 20KB, which makes the The parameter download is simple and convenient, and the parameters can be transmitted through the Internet or copied with a mobile device; the function is powerful, and the parameter setting can realize independent use or mixed use of various consumption methods.
(2) Handheld hardware upgrade: Get rid of the traditional upgrade method of connecting to the computer to burn the CPU, and the upgrade file in the form of a file makes the upgrade more convenient and flexible. Therefore, the hardware can be easily upgraded as long as there is the latest CPU upgrade or the customer needs some special functional modifications.
4. Scalability
The design of the company’s handhelds is designed from the perspective of a card, and has the ability to be compatible and extended to catering, Water control, attendance and other systems.
5. Normative
(1) GB/T18239-2000 General Specification for Integrated Circuit (IC) Card Readers and Writeers.
(2) GB9254-1998 “Information Technology Equipment Radio Disturbance Limits and Measurement Methods” Standard Class A requirements.
(3) GB/T17618-1998 “Information Technology Equipment Immunity Limits and Measurement Methods”.
(4) CJ/T166-2006 “Application Technology of IC Card in Construction Industry”.
(5) CJ/T243-2007 “Construction Industry Integrated Circuit (IC) Card Product Inspection” and other standards are implemented.
6. Aesthetics
The streamlined design style, beautiful appearance, atmosphere, in line with people’s aesthetic point of view; elegant and delicate 24-key keyboard The layout is delicate and delicate like a curve; the whole machine is small, light, sturdy and durable, the buttons are beautiful and sensitive, and it is easy to operate, which is very suitable for use in public transportation and movable places; the LCD display is clear, the whole machine feels good and adopts a non-slip design.
