Embodiment Construction

[0034] In the following, in conjunction with the accompanying drawings, a touch-type liquid crystal display is used as an example to further illustrate the display of keyboard key values ​​and the input function of key positions.

[0035] step 1.

[0036] Use the single-chip microcomputer to complete the initialization of the liquid crystal display, and display the key arrangement of the traditional number "0-9" keys on the display, as well as the three function keys "Start", "OK" and "Cancel", such as figure 1 . The function of the "start" key is to allow the internal digital analog circuit to produce a key value arrangement different from the traditional key value arrangement. The function of the "OK" key is to press the key to represent the end of an input after the user's input is completed and the input is confirmed to be correct. After receiving the instruction, the single-chip microcomputer completes the confirmation operation of the input password and rearranges the d...

Description

technical field [0001] The invention belongs to the field of computer equipment and relates to electronic technology, in particular to an intelligent security keyboard whose key value can be changed randomly. Background technique [0002] At present, the keyboard has become a kind of most important computer peripheral input device. It can not only complete normal character input, but also as a password input device, has been widely used in various fields of society, such as financial fields such as banks and stock markets. [0003] However, as a password input device, the existing keyboards have poor security. The main reason is that the key values ​​of each key on the keyboard are fixed.
