Embodiment

[0016] refer to Figure 1-2 , a special projector for an open classroom, comprising a projector body 1, an alarm 2 is installed on the front side of the projector body 1, a wireless transceiver device 4 is installed on the top of the projector body 1, and both sides of the projector body 1 are equipped with There is a heat dissipation port 5, a timer 6 is installed on one side of the heat dissipation port 5, a temperature sensor 10 is installed on the inner wall of the projector body 1, a main control board 3 and a rotating motor 9 are arranged in the projector body 1, and the main control board 3 A storage module and a control module are arranged on the top, a support rod 7 is provided at the bottom end of the projector body 1, and one end of the support rod 7 extends into the projector body 1, and the support rod 7 is connected with the output shaft of the rotating motor 9, and the support rod The bottom end of 7 is provided with telescopic rod 8, and support rod 7 is cavity...

example 1

[0018] Example 1: When working, the timer 6 counts and the temperature sensor 10 monitors the temperature in the projector body 1 in real time. When the temperature in the projector body 1 reaches a certain set value, the control module controls the cooling motor to drive the fan blades to rotate at a high speed. The internal heat is discharged outside the projector body 1 in time to improve the service life of the projector; at the same time, the monitoring device 12 collects the situation in the classroom at different angles regularly, and sends it to the management terminal through the wireless transceiver device 4. When the module observes an emergency fault, the processing module at the management end transmits the signal to the control module, and the control module controls the alarm 2 to send out an alarm. The degree of automation is high, ensuring the safety and quality of the open classroom.

Abstract

The invention discloses a special-purpose projector of an open classroom. The special-purpose projector includes a projector main body. The front side of the projector main body is provided with an alarm device. The top end of the projector main body is provided with a radio transmit-receive apparatus. The two sides of the projector main body are both provided with heat radiation openings. One side of the heat radiation openings is provided with a timer. The internal wall of the projector main body is provided with a temperature sensor. The projector main body is provided with a main control board and a rotation motor. The main control board is provided with a storage module and a control module thereon. The bottom end of the projector main body is provided with a supporting rod. The bottom end of the supporting rod is provided with a telescopic rod which is sleeved inside the supporting rod. The supporting rod is provided with a telescopic motor therein. According to the invention, the projector uses the alarm to sound an alarm when maloperation occurs, acquires conditions in the open classroom at different angles, removes inside temperature outside the projector main body in time, increases service life of the projector, has high automation level, and guarantees safety and quality of the open classroom.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a special projector for an open classroom. 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 the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. Judging from the future development form of the industry, education is still the pillar area for the future development of the industry. As for the projectors dedicated to open classrooms, the structure and performance of the current teaching projectors are single. Due to the large number of students and too many uncontrollable factors of personnel, the equipment and teaching environment...
