Problems solved by technology

[0004] The technical problem to be solved by the present invention is: under the condition of no lights at night, the visual effect created by the light emitted by the computer screen alone is not good, which is harmful to the eyes; if you turn on the computer by feeling, it is easy to touch the legs of the table. Sharp places such as computer hardware can cause injury; induction lights are installed on the computer to prevent misoperation during the day; the invention provides a computer with the function of detecting human body infrared rays that solves the above problems

Embodiment 1

[0023] Such as Figure 1 to Figure 5 As shown, the computer with the function of detecting human infrared rays includes a single-chip microcomputer 1, an infrared pyroelectric sensor 2, a power supply module 3, a lighting module 4, and an illumination detection module 5; The input terminal is connected, the infrared pyroelectric control terminal of the single-chip microcomputer 1 is connected with the output terminal of the infrared pyroelectric sensor 2, the lighting control terminal of the single-chip microcomputer 1 is connected with the control terminal of the lighting module 4; The electrical sensor 2 receives the infrared radiation from the human body and converts it into an electrical signal and sends it to the single-chip microcomputer 1. The illumination detection module 5 detects the current brightness in real time and then converts it into an electrical signal and sends it to the single-chip microcomputer 1. The single-chip microcomputer 1 processes the signal throug...

Embodiment 2

[0028] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the power supply module 3 is an LM7805 integrated voltage regulator, and the 7V power supply is rectified and filtered and sent to the LM7805 for voltage stabilization, and then output to a 47UF and 0.1UF capacitor for further filtering. In addition to the ripple, a 5V regulated power supply is obtained to supply power to the microcontroller.

[0029] Among them, capacitor C1 and capacitor C4 are used to bypass the high-order harmonics in the power supply. These high-order harmonics cannot be filtered out when the capacitor is decomposed, because its own latent inductance is very large, which will hinder high-frequency The passage of ingredients.

Embodiment 3

[0031] Such as Figure 1 to Figure 7 The difference between this embodiment and Embodiment 1 to Embodiment 3 is that the operational amplifier A1, operational amplifier A2, operational amplifier A3, and operational amplifier A4 are all LM324 chips.

Abstract

The invention discloses a computer with the function of detecting infrared rays of a human body, which solves the problem that the visual effect created by the illumination emitted by the computer screen alone is poor under the condition of no light at night, and has certain harm to the eyes; with the feeling to open the computer, the user is easy to bump against the foot of the desk, computer hardware or other sharp places, causing harm. The computer of the invention comprises a single chip microcomputer, an infrared pyroelectric sensor, a power supply module, a lighting module and an illumination detection module. The invention has the advantages of lighting the lamp when a person comes close, turning off the lamp when the person leaves, saving energy, creating a good visual atmosphere,protecting eyes and the like.

Description

technical field [0001] The invention relates to a computer accessory, in particular to a computer with the function of detecting infrared rays of a human body. Background technique [0002] Computers are widely used in daily life. For many office workers, they need to use computers when they go to work during the day, and they also need to use computers when they go home at night, and they use computers until late at night. [0003] There is plenty of light during the day, but at night without lights, if you turn on the computer by feeling, it is easy to touch sharp places such as table legs and computer hardware, causing damage, which is very inconvenient; after turning on the computer at night, compared with daytime, The visual effect created by the light emitted by the computer screen alone is not good, and it is harmful to the eyes; if a human sensor light is installed on the computer, the problem derived is that the sensor light is misoperated during the day and wastes ...
