[0025] The following is an example of entering the fingerprint of the first user. [0026] Firstly, three short-circuit blocks are respectively inserted into the JP JP JP3 to set RB5 ' RB6, RB7 = 000, and the fingerprint can be entered at this time, and the user touches the fingerprint input unit through multiple times (such as 3 times). 2, the fingerprint input unit 20 inputs the fingerprint information input by the user three times and transmits it to the microcontroller U1, and the microcontroller ui processes the received three fingerprint information through an internal program to extract the combined features and generate The fingerprint template is stored in the storage crystal (4), and the fingerprint input of the first user is completed. The principle of entering the fingerprints of other users is the same as the principle of entering the fingerprints of the first user, and will not be described here. When the user touches the fingerprint input unit 2(), the fingerprint input unit enters the user's & texture information and transmits it to the micro control_, and the microcontroller U1 will receive the fingerprint information of the user. The fingerprint template stored in the old memory chip is compared and judged _ _, if not, the micro-control device U1's turn-out pin ΚΒ 2 · _ low-level signal, the diode LE1 is turned on red light Prompting the user to turn on the power window. For example, the micro-control l§Ul's turn-out pin outputs a high-level signal, and the base of the transistor Q1 receives the high-level signal to turn on the collector of the electro-crystal. A low level signal is output to the switch signal terminal PWR of the motherboard, so that the computer is turned on. After the computer is turned on, the output terminal RB3 of the microcontroller U1 outputs a low-level signal, and the light-emitting diode LE2 is turned on to emit green light to remind the user that the computer has been turned on. After the computer is turned on, the voltage source P5V0 is The system is powered and powered. At this time, the diode D1 is turned off and the battery B1 is no longer supplied with power. This can extend the service life of the battery B1. 0992026552-0 099114974 Form No. A0101 » 10 pages/Total 18 pages 201140376 [0028] The keyboard of the present invention also has a function of detecting the amount of power of the battery B1: [0029] When the battery B1 is low in power, then the resistors R1 and The node voltage is lower than a certain value, for example 5V 'microcontroller U1 detects that the voltage of the input terminal RA0 is less than a certain value, for example 5V 'the output terminal RC5 of the microcontroller U1 outputs a two-level signal, the transistor Q2 The base receives the high level signal and the buzzer Z1 is activated to sound a warning tone to remind the user that the battery B1 is low. It is also possible to set the pulse of the old output terminal RC5 of the microcontroller to the high and low level intervals according to actual needs, so that the buzzer Z1 intermittently emits a sound to remind the user that the battery B1 needs to be replaced. [0030] The keyboard of the present invention can realize the booting function of the computer by simply touching the fingerprint input unit 2 设置 set on the keyboard, thereby facilitating the user's machine.
