Benefits of technology

This patented technology describes an improved way that allows users to adjust their lights based upon how much sunlight they receive during different times throughout each day or weekday. It simplifies its construction while still providing accurate results over time.

Problems solved by technology

This patented technical solution involves controlling how much solar radiation goes into each space by turning it up or down based upon factors like changes in elevation angles at different times throughout the year (day). By doing this, less power can be used while still providing good quality lighting without sacrificing too much electrical capacity needed.

Embodiment Construction

[0019] As shown in the figure, a natural lighting control system includes a human body sensor, an illuminance sensor, a controller, a curtain control module, and a lighting control module, and is characterized in that: the output terminals of the human body sensor and the illuminance sensor are connected to the controller, The output end of the controller is connected to the curtain control module and the lighting control module. The controller is a fuzzy controller, which mainly consists of three parts: fuzzification, fuzzy rules, fuzzy reasoning and clarity.

[0020] (1) Fuzzification

[0021] Fuzzification is the process of transforming the determined value of the input quantity of the fuzzy controller into the value of the corresponding fuzzy linguistic variable, and the corresponding linguistic variable is defined by the corresponding degree of membership.

[0022] If take deviation e as input, through fuzzification process, use fuzzy language variable E to describe devia...

Abstract

The invention relates to the technical field of illumination equipment, and in particular discloses a natural lighting control system. The output ends of a human body inductor and an illumination sensor are connected with a controller; the output end of the controller is connected with a curtain control module and an illumination control module; and the controller is a fuzzy controller and mainly comprises three parts which are fuzziness, fuzzy control rule and fuzzy reasoning, and certainty respectively. The natural lighting control system has the following advantages that: the system has a simple and clear structure; as solar gain has negative effect on summer needing cooling and is favorable to the reduction of heating power in winter, the system gives performance indexes for the working conditions in winter and in summer respectively, wherein an illumination index and a temperature index are focused in summer, while the illumination index and an air conditioner heating power index are focused in winter; models indicating relationships between the opening of a curtain and the illumination of a working surface, between the opening of the curtain and indoor temperature and between the opening of the curtain and the solar gain are established respectively; and a control part is simple and convenient to realize.
