Embodiment 1

[0013] a kind of like figure 1 , figure 2 The shown projector with automatic timing function includes a casing 1 and a lens 5 arranged in front of the casing 1, and also includes a display screen 3 and an LED light 2 arranged on the top surface of the casing 1; it is arranged above the lens 5 The photoelectric sensor 4 is arranged on the integrated circuit board in the housing 1, and the integrated circuit board is integrated with a signal processing circuit and a single-chip microcomputer;

[0014] The projector with automatic timing function can detect whether the projector lens is emitting light, and record the light emitting time of the lens. When the use time exceeds the set time, it will send a reminder message through the LED lamp, which has the function of protecting the projector light source , Avoid using the projector for a long time so that the service life of the projector will be affected.

Embodiment 2

[0016] Above-mentioned photoelectric sensor 4 is used for detecting whether the lens of projector is opened, and signal is sent to signal processing circuit; Said signal processing circuit is used for receiving the signal that photoelectric sensor 4 sends, and carries out digitization, then sends signal to single-chip microcomputer; The single-chip microcomputer is used to receive the signal sent by the signal processing circuit, then starts timing, and controls the display screen 3 to display the timing result, and controls the LED lamp 2 to send a reminder message; the above-mentioned projector with automatic timing function also includes a power supply circuit, and the The power circuit is connected in parallel with the power supply of the projector, and provides power for the photoelectric sensor 4, signal processing circuit, single-chip microcomputer, LED lamp 2 and display screen 3.

Abstract

The invention belongs to the technical field of electronic products, and particularly relates to a projector with an automatic timing function. The projector comprises a shell and a camera lens arranged on the front face of the shell, and further comprises a display screen and an LED lamp arranged on the top surface of the shell, a photoelectric sensor arranged above the camera lens and an integrated circuit plate arranged in the shell; a signal processing circuit and a single chip microcomputer are integrated on the integrated circuit plate. The projector with the automatic timing function can detect whether the camera lens of the projector is luminescent and record the luminescent time of the camera lens, when the usage time exceeds the preset time, reminding information can be sent by the LED lamp, a function of protecting a light source of the projector is achieved, and the fact that the service life of the projector is affected because the projector is used for a long time is avoided.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a projector with an automatic timing function. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. Existing projectors do not have a timing function and cannot record the usage time of the projectors, resulting in long-term use and affecting the service life of the projectors. Contents of the invention [0003] The purpose of the invention is to overcome the problem that the current projector cannot record the usage time. [0004] For this reason, the present invention provides a kind of projector with automatic timekeeping function, comprises housing and the lens that is arranged on the front of the housing, also includes the display scree...
