Embodiment Construction
[0019] The technical solutions and other beneficial effects of the present invention will be apparent through the detailed description of specific embodiments of the present invention below in conjunction with the accompanying drawings.
[0020] figure 1 It is a structural schematic diagram of the projection display device of the intelligent switch machine. It includes a projector body 110 , a detection unit 120 , a power control unit 130 and a mode setting unit 140 .
[0021] The projector body 110 performs projection and display.
[0022] The detection unit 120 detects whether there is a user in the environment where the projector body 110 is used, and transmits the detection result to the power control unit 130 .
[0023] Preferably, the detection unit 120 uses an infrared probe for detection. The infrared probe can judge whether there is a user in the use environment according to whether it detects the infrared rays released by the body temperature. When the infrared p...

The invention relates to a projection development device started or stopped intelligently, which comprises a projector body and also comprises a detection unit and a power supply control unit; the detection unit detects whether a user is in the use environment of the projector body or not, and transmits a detection result to the power supply control unit; and the power supply control unit receives the detection result detected by the detection unit and sets the use state of the projector body. The invention judges whether the projector body needs to be used or not by detecting whether the user is in the use environment or not, the projector body is managed and is automatically in a standby or stop state when at an unattended state, intelligent control is carried out on the projector body,manual operation is not needed, very large convenience is brought to the user, the wastage of energy resources, which is caused by the condition that the user forgets to stop the device, is avoided, and the energy resources are greatly saved.
Description
【Technical field】 [0001] The invention relates to a projection display device, in particular to a control method for standby, shutdown and start-up of the projection display device. 【Background technique】 [0002] At present, projectors are widely used in conferences, teaching and other fields. [0003] The projector consumes a lot of power when it is working. If you forget to turn it off after use, or turn it off automatically when you are ready to use it, it will cause a great waste of energy and bring great inconvenience to the operator. 【Content of invention】 [0004] In view of this, it is necessary to propose a projection and display device that can be switched on and off intelligently, aiming at the problems that the above-mentioned projector forgets to turn off the projector when it is not in use and that it is turned off when it is in use, causing a large amount of energy waste. [0005] In addition, it is necessary to propose a control method for a projection di...
