Abstract

The invention belongs to the technical field of teaching equipment, and discloses a projector with a video recording function. The projector comprises a projector main body and a photography machine;and auxiliary lamps are arranged on the two sides of the projector main body. Two fans in the projector correspond to two exhaust fans, so that the heat dissipation is guaranteed while the internal air is stably flowing, and the service life of the projector is prolonged; the auxiliary lamps are arranged outside the projector, and the projection position of the projection image is controlled, andthe projection image is prevented from falling out of video canvas; the projector is combined with a freely telescopic and rotating camera, capable of adjusting the recording angle manually, and is more convenient to use; the camera is remotely controlled to collect video signals, and the video signals are converted into digital signals through an A / D converter, then the digital signals enter a wireless video server through code pressing, and the wireless video server has storage and transmission functions, so that the direct video transmission to external equipment is carried out, the structural weight of the camera is reduced, the storage space of the videos is not limited, and therefore, the projector is more convenient to use and apply.

Description

technical field [0001] The invention specifically relates to a projector with video recording function, which belongs to the technical field of teaching equipment. Background technique [0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, and can also be used to measure the surface shape of a non-through hole and observe the surface of a part with reflected light. The projector is a tool that is needed for multimedia teaching now. The existing projectors are generally fixed on the top of the classroom, so the heat dissipation effect is poor. meet the needs of teaching. Contents of the invention [0003] The technical problem to be solved by the present invention overcomes the existing defects and provides a projector with video recording function, which can effectively solve the problems in the background technology. [00...
