Description

Technical Field

[0001] The invention relates to a key detection device and a method thereof, belonging to the technical field of key detection. Background Art

[0002] A smart terminal device with physical functions and numeric keyboard keys needs to undergo consistency testing during mass production, i.e., key validity testing. Conventional keyboard key testing methods are to open the corresponding application interface (such as WORD, Notepad, etc.) in the WINDOW window interface, press the corresponding function and numeric keyboard keys, that is, display the corresponding function on the interface or view the corresponding key content, indicating that the corresponding physical function and numeric keyboard keys are valid. For example, to detect the validity of the numeric key "1": open Notepad or this counter on the display interface, enter "1", and the corresponding interface displays the number "1", which verifies that the device keyboard key "1" is valid; to detect the validity of the function key "Delete": open Notepad on the application interface, enter the number "X", move the cursor to the front of the character "X", and press the "Delete" key. At this time, the character "X" is deleted, which verifies that the device keyboard key "Delete" is valid; and so on, enumerate all the numeric keys one by one: 0~9, dot; and all the function keys: up, down, left, right, zoom in +, zoom out -, menu, backspace, delete, and confirm.

[0003] It can be seen that different function keyboard keys and numeric keyboard keys require opening the corresponding function interface or application software to verify the validity of the key. In the mass production process of intelligent control terminal devices with physical functions and numeric keyboard keys, the time cost difference of the validity detection of physical keyboard keys is closely related to the time cost difference of the actual function interface or application software corresponding to the keyboard key. Conventional testing methods are inefficient and prone to missed detection and false detection. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a key detection device and method thereof. The content of the present invention application is to design a keyboard key test tool according to the corresponding physical keyboard key value table. Use the programming tool VS2010 to write a program and make a display interface corresponding to the keyboard. By capturing the key value generated when pressing the key and performing key value data matching analysis on the key value, the validity of the keyboard key is determined. By enumerating all the keyboard keys one by one, it is tested whether all the keyboard keys are valid.

If so, it is determined that all key icons are lit or all key icons are detected and passed.

[0007] Preferably, the processor is used to determine whether to scan and traverse the key-value table. If the processor determines that the key-value table is not scanned and traversed, this step is repeated.

[0008] Prioritize, start the key detection procedure; Determine whether a key in the function key area or the numeric key area is pressed, and if so, enter the interrupt processing step.

[0009] Preferably, it is determined whether a key in the function key area or the number key area is pressed, and if not, it is cyclically detected whether a key in the function key area or the number key area is pressed.

[0023] Combine the following Figures 1 to 7 The present invention application is further described.

[0024] 1. Smart terminal devices mainly consist of three hardware components, namely processor, display screen and digital / function key area, such as Figure 1 The signal is generated by the digital / function key area of ​​the human-machine interface and transmitted to the central processor, and the signal is sent to the display screen for display after being processed. Figure 6 The number keys include 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, . , OK, Figure 7 The function keys include 3G, 3D, Menu, Backspace, Delete, OK, Zoom In +, Zoom Out -.

[0025] According to the function key area and the number key area on the panel of the intelligent terminal device, the corresponding function key values ​​and number key values ​​are used to establish a corresponding keyboard key value table. Figure 3 As shown, the interface of all keyboard keys to be tested is displayed on the display screen of the intelligent terminal device, which includes three areas, namely, the function key area, the number key area and the test log area.

[0026] 2. Based on Figure 1 Based on the hardware architecture, a test software tool is developed. The test software consists of two parts: the main program - key cycle detection program and the interrupt response program. The test software process is as follows Figure 2 As shown in the figure, after the program is started, it first enters the main program - key cycle detection program, and enters the interrupt response program through continuous cycle monitoring and scanning. After all interrupt response programs are completed, the interrupt response program is exited and returned to the main program - key cycle detection program to end the detection.

[0027] The following will explain in detail the software testing program operation process.

[0028] 3. When the smart terminal device is turned on normally, start the keyboard key test program and initialize the test environment. Start to detect whether there are any keyboard keys pressed in a loop. Compare the keys on the physical keyboard of the smart terminal, type the function keys and number keys respectively, and enter an interrupt when a key signal is detected. The interrupt starts, reads the key value signal and starts to look up the table. like Figure 4As shown, the interface on the display screen lights up the corresponding function button icons and number button icons respectively, and continues to search for the remaining untested button values ​​against the key value table, and displays feedback in the test log area.

[0029] like Figure 5 As shown, when all the keyboard keys are tested, that is, after the test program traverses all the key value tables, the icons corresponding to the function key area and the number key area of ​​the display interface are all lit up, and the log area displays a prompt that the test is completed. Exit the interrupt program.

[0030] 4. The keyboard key test is completed.
