The electric mortise lock, the display screen, the pressure sensors, the fingerprint acquisition module and the confirmation key are respectively and electrically connected with a control circuit board arranged in the outer panel or the inner panel.
When a fingerprint password is input through the fingerprint password input module, an index finger, a middle finger, a ring finger and a little finger are respectively and correspondingly pressed on four fingerprint acquisition modules which are arranged along the left and right directions of an outer handle, each finger presses each fingerprint acquisition module according to the password sequence to enable the pressure on a pressure sensor at a corresponding position to reach a preset value, the pressure value on the pressure sensor is displayed on a display screen in real time, 4 lines of two-digit numbers are displayed on the display screen in real time, 4 lines of numbers respectively correspond to the pressure values of the four pressure sensors which are arranged from left to right, and when the pressure value on the pressure sensor at the corresponding position is zero, a corresponding line on the display screen dynamically displays a pseudo-random number; when the pressure sensor at each position presses a preset value, the confirmation key is pressed down by a thumb, after the confirmation key is pressed down, the control circuit board extracts fingerprint information acquired by the fingerprint acquisition module at the corresponding position to form four fingerprint sequences which are arranged in sequence and have different pressure values, the control circuit board compares the fingerprint sequences with fingerprint sequence information set by a user independently, if the fingerprint sequence information is consistent, the password input is judged to be correct, the control circuit board controls the electric mortise lock to execute an unlocking step, if the fingerprint sequence information is inconsistent, the password input is judged to be wrong, and the user is prompted to input the password again through the display screen.
The real-time pressure value displayed on the display screen has the precision of 0.1 newton, and is converted into an integer by multiplying by 10 to be displayed, and if the pressure value is 0.2 newton, 2 is displayed on the display screen (hereinafter, the value displayed on the display screen is referred to as the pressing force).
The preset value of the pressure is a fixed value, and when the pressure sensor is pressed, and the difference value between the real-time pressure value and the set fixed value is less than 0.2 Newton, the real-time pressure value is considered to be equal to the preset value; the accuracy of the real-time pressure value displayed on the display screen is 0.1 newton.
In order to more directly understand the key of the fingerprint password input module, the following examples further illustrate: for example, the index finger, the middle finger, the ring finger and the little finger correspond to 1, 2, 3 and 4 respectively, if the password is set to 2143 and the pressing force is set to 8765 (the selectable pressure value is 1-8), the middle finger is pressed down in sequence, the confirmation key is pressed down when the second column on the display screen is displayed within the range of 6 to 10, the confirmation key is pressed down when the index finger is pressed down and the first column on the display screen is displayed within the range of 5 to 9, the little finger is pressed down, the confirmation key is pressed down when the fourth column on the display screen is displayed within the range of 4 to 8, and the confirmation key is pressed down when the ring finger is pressed down finally and the third column on the display screen is displayed within the range of 3 to 7.
