When the lighting facilities need to be turned off due to uncertain factors, the key for turning off all the facilities can be clicked to turn off all the lighting facilities in the classroom.
The application process of the automatic closing device for the classroom lighting facilities provided by the invention is as follows:
(1) when the device is used for the first time, all timers are set to zero; after the lighting facilities in a certain area of the classroom are automatically turned off, the corresponding timer is set to zero and enters a standby state;
(2) the lighting facilities in a certain area of the classroom are powered on and are in a working state, the camera collects images in the classroom once every a period of time (working day and holiday are respectively every a minute and b minutes), and the control unit determines whether people exist in each area of the classroom according to the images provided by the image processing unit;
(3) if no person is detected in a certain area in the classroom, a timer corresponding to the area starts to time; if the existence of the personnel is detected in a certain area in the classroom, the timing unit corresponding to the area maintains the original state;
(4) under the condition that no person exists in a certain area in a classroom, judging whether a person appears in x minutes or not; if people appear in x minutes, the timing unit is set to zero and enters a standby state; if no personnel appear in the area until x minutes, the control unit sends a closing control signal to the switch unit so as to close the lighting facilities in the corresponding area, and meanwhile, the timing unit is immediately set to zero and stands by;
(5) and (4) returning to the step (2).
The invention provides an automatic closing device and a method for classroom lighting facilities, which have the main advantages that (1) the lighting device is closed only when no person exists in a certain area within a set time threshold, and the area with the person is not influenced; (2) even if no personnel exist in a certain area, the lighting facilities are not immediately turned off, but are turned off after waiting for a set time threshold, so that frequent switching of the lighting facilities can be avoided, and the service life of the facilities is prolonged. The automatic closing of the lighting facilities in the classroom is realized by reasonably arranging the image acquisition unit, the image processing unit, the control unit, the switch unit and the timing unit, whether the lighting facilities need to be automatically closed or not can be determined according to the actual situation in the classroom, and the intelligent lighting facility closing function is realized; meanwhile, the device can also enable managers to carry out overall management on all lighting facilities on the operation unit, and the lighting facilities in the classroom can be managed more conveniently. Compared with the existing device for automatically turning off the light, the intelligent degree of the system is improved, the better energy-saving and emission-reducing effects are obtained, and the device has practical application and popularization values.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The method disclosed by the embodiment corresponds to the system disclosed by the embodiment, so that the description is simple, and the relevant points can be referred to the system part for description.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
