Abstract
The utility model relates to an electric energy-saving automatic control apparatus for a classroom, wherein the apparatus comprises human body induction sensors, a phase discriminator, a light sensor and a PLC. The phase discriminator carries out phase comparison on signals from the two human body induction sensors so as to identify whether a motion is one entering a classroom or leaving the classroom; if the motion is one of entering the classroom, the total number of people in the classroom is increased by 1; otherwise, the total number of people in the classroom is reduced by 1. The light sensor detects the situation of ambient lights. According to the number and the information from the light sensor, the PLC executes a program output instruction to control the number of fans and lamps for working. Therefore, an energy-saving objective is achieved.
Description
Affiliated technical field
The utility model relates to a kind of classroom electricity consumption energy-saving automatic control device, especially can control automatically the work of classroom consumer, to realize purpose of energy saving.
Background technology
At present, the Kai Heguan of known classroom consumer such as daylight lamp, fan is that the people manually controls, find in the reality people from classroom seldom or the no one or daytime available light sufficient, fan and lamp are but all opened, and have caused the waste of the energy.
Summary of the invention
In order to remedy the problem that there is waste in existing classroom electricity consumption, the utility model provides a kind of electricity consumption energy-saving automatic control device, can reach purpose of energy saving according to the quantity that what and natural light situation of classroom number are controlled consumer work automatically.
The utility model solves the scheme that its technical matters adopted: adopt the classroom electricity consumption energy-saving automatic control device of being made up of human body sensor, phase detector, light sensor and PLC.Phase detector carries out the phase bit comparison to the signal from two human body sensors, is to get into the classroom or leave the classroom with identification, if get into the classroom then the classroom total number of persons add 1, otherwise subtract 1; The situation of light sensor ambient light, PLC realizes purpose of energy saving according to the quantity of the sharp light sensor executive routine of number output order control fan and lamp work.
The beneficial effect of the utility model is, and is simple in structure, easy to install, reliable operation, and cost is low, favorable expandability, energy-saving effect is obvious.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the structural map of an embodiment of the utility model.
Embodiment
In the accompanying drawings, at correct position several light sensors are installed, two human body sensors are installed before and after each doorway, the front and back certain distance that staggers according to the structure in classroom and area.The input interface of each sensor and PLC is connected, fan, daylight lamp is connect the output terminal of PLC.
In an embodiment shown in the drawings, during use, press the PLC starting switch, classroom electricity consumption energy-saving automatic control device is started working.If at this moment the people is arranged successively successively through two human body sensors; Then there is the leading or hysteresis on the phase place in the signal of two human body sensor generations; Phase detector compares to identify to this signal and gets into the classroom or leave the classroom; If get into the classroom then the counter among the PLC make the classroom total number of persons add 1, otherwise subtract 1; Light sensor also constantly inputs to PLC with detection signal, PLC according to number what with the detection signal of light sensor, execution PLC program realizes the automatic control to daylight lamp and electric fan working quantity.
Claims (1)
1. a classroom electricity consumption energy-saving automatic control device is characterized in that: be made up of human body sensor, phase detector, light sensor and PLC.
