Embodiment Construction

[0015] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited.

[0016] Such as figure 1 As shown, the lighting control system includes a power supply module, a light sensing module, a microwave sensing module and a data processing module, among which

[0017] The power supply module includes an AC transformer, a rectifier circuit and a voltage stabilizing circuit. In this embodiment, the circuit adopts a 220V / 15V AC transformer to generate a voltage. After the rectification circuit, the voltage stabilizing circuit generates a 12V voltage stabilizing source. After the three-terminal voltage stabilizing integrated circuit, a 5V voltage source is generated to provide power for the light sensing module, the microwave sensing module and the data processing module.

[0018] The light sensing module includes a photoresistor, a comparator circuit, a triode, a relay and an ...

Abstract

The invention discloses an illumination control system, which comprises a power supply module, a light sensing module, a microwave sensing module and a data processing module, wherein the microwave sensor is used for collecting a somebody signal or a nobody signal, so that the large-range spatial sensing control of classrooms and roads can be realized, the lightening and the duration of a lamp can be intelligently controlled through a single chip microprocessor, and the problem for saving and reasonably utilizing the electric energy can be effectively solved. The illumination control system has the characteristics of wide sensing range, sensitivity in reaction, precision in automatic control, energy conservation and environmental friendliness and is particularly applicable to public places such as the classrooms, the roads and offices.

Description

technical field [0001] The invention relates to a sensing system, in particular to a lighting control system for controlling a wide range of spaces such as roads and classrooms. Background technique [0002] In today's energy shortage, energy saving has become a goal that people are constantly pursuing. However, there are still unreasonable situations where the lights are still on when there is no one in the classroom or on the road; and it is unreasonable that the lights are not turned on when it is suddenly cloudy, windy and rainy. With the advancement of science and technology and the increasing proportion of lighting electricity consumption in the total electricity consumption, people strive to realize the development of lighting fixtures along the direction of low cost, energy saving, environmental protection, and intelligent control. The existing various induction lamps have basically realized the automatic control function, but there are still some deficiencies. For...
