Description

A Classroom Lighting Energy Saving Controller

technical field

The invention belongs to the field of lighting energy saving, in particular to a classroom lighting energy saving controller.

Background technique

In today's increasingly tense energy environment, energy conservation and emission reduction are particularly urgent. With the development of China's education and the expansion of classrooms, the demand for classroom lighting in colleges and universities is also increasing, and the electricity load of classrooms is increasing. However, the management and control methods of classroom lighting systems are backward, and the phenomenon of waste of electricity for classroom lighting is relatively large. serious. In order to solve the phenomenon of electricity waste in classrooms in colleges and universities and improve the efficiency of electricity consumption, the present invention adopts the strategy of monitoring the classroom lighting in different areas, combines the sensor to collect the measured environmental signals in real time, and through the analysis and processing of the control unit, it can accurately control the switch on and off of the lights. The number of lights and the area where the lights are turned on can realize the reasonable control of classroom lighting and other resources, so as to achieve the intelligent energy-saving control management and optimization of the existing classroom lighting system in colleges and universities.

It has significant technical effects: improve the intelligence of classroom lighting management, liberate human resources, improve the efficiency of electric energy use, realize intelligent and precise measurement and control of college classrooms, especially self-study rooms, and realize the technical update of classroom lighting management. At the same time, the design structure Simple, economical, reliable and easy to popularize and use.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only These are some embodiments of the present invention.

Detailed ways

The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawing 1, the following embodiments are explanations of the present invention and the present invention is not limited to the following embodiments.

Example 1:

As shown in Figure 1, the present invention can realize effective intelligent control of classroom lighting. Its input parameters are mainly information such as classroom light intensity, number of people and its location. Choose from the manual mode, the manual mode is the normal classroom working mode; in the automatic mode, when a certain light intensity is met and there are people, the lighting can be automatically turned on, and at the same time combined with the pyroelectric infrared sensor to determine the area where the personnel are distributed, Realize the precise lighting of the lighting lamps in specific zones, and at the same time, the display circuit can display the number of people in the classroom in real time. When it is impossible to determine the position of people in the classroom through the pyroelectric infrared sensor, all the lights will be turned on; Automatic delay cut off the power, saving energy.

In addition, it should be noted that the specific embodiments described in this specification may be different in terms of parts, shapes and names of components. All equivalent or simple changes made according to the structure, features and principles described in the patent concept of the present invention are included in the protection scope of the patent of the present invention.
