Abstract

The invention relates to a detection method for activating lock of a computer screen, which comprises the following steps that an ultrasonic ranging module is used for detecting whether a target exists in a detection range; if the target exists in the detection range and the distance of the target does not change in a plurality of seconds, the target is judged to be not a human body, the ultrasonic ranging module transmits a signal to the computer, and the computer automatically locks the screen; if the target exists in the detection range and the distance of the target changes in several seconds, the target is judged to be a human body, and the computer screen is normally used; if no target exists in the detection range, the ultrasonic ranging module transmits a signal to the computer, and the computer automatically locks the screen. According to the detection method for activating the lock screen of the computer screen, delay processing and judgment of various conditions can be carried out according to the signal of the ultrasonic ranging module, and the functions of direct judgment, static judgment and delayed lock screen are achieved.

Description

technical field [0001] The invention relates to the technical field of computer lock screens, in particular to a detection method for activating computer screen lock screens. Background technique [0002] Sensitive information exists inside the computers of many units or individuals, even on the screens, and cannot be freely obtained by irrelevant personnel. Therefore, whether it is Windows, Macos or Android, the computer system provides a lock screen button to lock the screen when the owner leaves to prevent information leakage; for computer lock screen, the user manually operates the mouse or manually combines "WIN" through the keyboard shortcut key + "L" or wait for the computer to turn on the automatic sleep mode (the computer will automatically lock the screen after detecting no operation for a preset period of time) can be realized. But sometimes, there are still situations where computer users are negligent, and they do not lock the screen in time when they leave, wh...
