Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described here according to the figures are only for explaining the present invention, and are not intended to limit the present invention.
[0015] Such as figure 1 As shown, the present invention includes a temperature detection module, a CPU, an intelligent focusing module, and a focusing motor.
[0016] Among them, the temperature detection module monitors the temperature in the casing in real time. When the temperature in the casing reaches a certain temperature value in the set temperature value list, the temperature detection module will send the temperature value to the CPU; The received temperature value generates a control instruction and outputs it to the intelligent focusing module; the intell...

The invention aims to provide an intelligent focusing system capable of avoiding lens blur of a projector caused by a long-term operation of the projector, and the intelligent focusing system can ensure a long-term stable operation and a clear projection image of the projector. The intelligent focusing system comprises a temperature detection module, a CPU, an intelligent focusing module, and a focusing motor, wherein the temperature detection module is used for monitoring the temperature in the projector shell in real time; when the temperature in the projector shell reaches a certain temperature value in a temperature value list, the temperature detection module sends the temperature value to the CPU; the input end of the CPU is connected with the temperature detection module; the CPU generates a control instruction according to the received temperature value, and outputs the control instruction to the intelligent focusing module; the input end of the intelligent focusing module is connected with the CPU; the intelligent focusing module generates a regulating signal to the focusing motor according to the received control instruction; the input end of the focusing motor is connected with the intelligent focusing module; and the focusing motor regulates the position of a lens group according to the regulating signal so as to realize the focusing function of the projector.
Description
technical field [0001] The invention relates to the field of projection, in particular to an intelligent focusing system for avoiding lens blurring of a projector. Background technique [0002] With the continuous development of science and technology, people have higher and higher requirements for the screen display of projectors. Projectors have become an indispensable office product in life and an irreplaceable large-screen audio-visual machine in life. After the projector works for a long time, the light bulb, CPU and other components will dissipate a lot of heat, and the temperature inside the projector will gradually rise, causing the lens group of the projector to expand due to heat and cause the projected picture to blur. Contents of the invention [0003] The object of the present invention is to provide an intelligent focusing system that avoids blurring of the lens caused by long-time operation of the projector, and can ensure that the projector works stably for...
