Method for rapidly inputting license plate numbers to PDA (personal digital assistant) equipment through virtual keyboard

Abstract

A method for rapidly inputting license plate numbers to PDA (personal digital assistant) equipment through a virtual keyboard includes: setting virtual keyboard programs in a system application layer of the PDA equipment, and dynamically binding edit box programs for inputting the license plate numbers to the PDA equipment with the virtual keyboard programs. The virtual keyboard comprises a display interface and an input interface, the display interface is used for displaying inputted characters, the input interface is provided with commonly used license plate Chinese character keys, uncommonly used Chinese character keys, letter keys and digit keys for correspondingly calling commonly used license plate Chinese character keyboard programs, uncommonly used Chinese character keyboard programs, letter keyboard programs and digit keyboard programs, the keys are selected for inputting by users, the virtual keyboard is turned off after inputting, and character data on the display interface are copied to the edit box programs, so that the license plate numbers are inputted. The virtual keyboard programs are set in the application layer, modification of a primary PDA operating system is omitted, Chinese and English input methods of the operating system are not involved, and the license plate numbers are rapidly inputted by the full-screen virtual keyboard.

Description

[0001] technical field [0002] The invention belongs to the technical field of intelligent equipment, and relates to a method for quickly inputting a license plate number of a PDA equipment through a virtual keyboard. Background technique [0003] In many fields such as parking management and traffic law enforcement, the entry of vehicle license plate numbers is often involved. In the entry of license plates, it involves the entry of various forms such as Chinese characters, English letters, numbers, etc., so it is relatively cumbersome. Under the embedded system screen, there are few buttons and it is inconvenient to switch input methods. Therefore, this problem is particularly prominent in occasions such as traffic law enforcement and parking management that require hand-held PDAs to input license plate information. At present, the method of inputting the license plate on the PDA generally mainly includes the following methods: [0004] 1) Through the physical keyboa...

Problems solved by technology

[0013] Application No. 200810249710.2 "A Method for Quickly Inputting License Plate Numbers Using the Keyboard of a Tax-controlled Cash Register" proposes a method of using hard keyboard input and modifying the input method to achieve rapid license plate entry. The disadvantages are: (1) This technology requires Modify the input method, or implement a new input method; (2) If the system does not support the QWERTY keyboard in the automatic Chinese character reminder or English character entry proposed in this technology, the problem of repeated codes cannot be solved

The disadvantage of this method is that there are actually many Chinese characters that can be used for license plate input, so the size of the physical keyboard will be large, which brings great difficulties to actual operation and carrying.
