Embodiment Construction

[0028]The problem to be solved by the present invention is achieved through the following scheme: the number signal is subdivided into two aspects, including the total number of people in the classroom and the number of people in each area of ​​the classroom. According to the partition control scheme, the system first determines the number of groups to turn on the lights according to the total number of people in the classroom. Then, according to the signal of the number of people in each area of ​​the classroom, the priority of turning on the lights is determined. After the lights in a certain area are turned on, check the number of people in the area again to meet the needs of further energy saving. Add the non-responsive number of people and delay action logic to the sorting control logic to enhance the accuracy and stability of the system. Add hysteresis comparison logic to the logic of deciding how many groups of lights to turn on, so that the system can work stably when ...

Abstract

The invention relates to an intelligent energy-saving control system for classroom lighting and fans. The intelligent energy-saving control system comprises a main control single chip microcomputer (SCM), a drive circuit, a display module, a people counting module, a clock module, an ambient luminous intensity detecting module and a power module. The modules provide four fundamental logical judgment bases of time, overall number of people in a classroom, number of people in an area and luminous intensity. According to the intelligent energy-saving control system for classroom lighting and the fans, area control for lights in the classroom can be achieved, and the SCM determines whether lights in each area are required to be opened according to a plurality of logical conditions; and additionally, the working stability of software is fully considered, and hysteretic compare logic and delay logic are arranged in a plurality of links.

Description

technical field [0001] The invention relates to an intelligent energy-saving control system for classroom lighting and fans, which belongs to the technical field of lighting control and is mainly used for detecting and controlling classroom lighting and temperature to realize intelligent and energy-saving classroom lighting. Background technique [0002] Now university classrooms mainly use switches to control lighting. This switch generally includes two types: one is the timing switch combined with manual mode, which controls the switch in combination with the school's work and rest time and the lighting needs of indoor personnel to control classroom lighting. This kind of extensive control method largely depends on people's consciousness. Even if the management is strict, it is inevitable to forget to turn off the lights, especially in the daytime, which will cause a lot of traffic accidents. Energy waste. The other is to use the illuminance sensor switch to automatically...
