Background technology
Classroom lighting is controlled the detection that is mainly used in dynamic human body for the application of pyroelectric infrared sensor at present, the human body when motion can detect human body through out-of-date, when people's transfixion of sitting down can produce serious erroneous judgement, this is because transducer is to utilize extraneous infrared radiation change and cause Voltage-output, and infrared radiation not have the time of action output voltage to cancel out each other and no-output.
Some mechanical modification technology have been there are at present, installation of sensors is made on rotating mechanism transducer produce relative motion with respect to human body and carry out human body, can there be some good improvement, but due to classroom, the local environments such as library are complicated, static thermal source and the human body of motion interfere with each other, and simple dynamic judgement has been not enough to human body recognition function.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of classroom human body infrared comprehensive judgment means, make whether existence and thermal source that it can intelligent decision thermal source are a kind of infrared sensing devices of surveying static human of human body.
A kind of infrared sensing device of surveying static human of the present invention, it comprises:
A light-sensitive sensors, for judging outside photoenvironment, sends data to processor;
A processor, for receiving the data of light-sensitive sensors output and judging, the process of judgement is: judge that whether classroom illumination is enough, enough circular waits detect classroom illumination, if illumination not, starts pyroelectric infrared sensor Static Detection program, judge whether to exist the human body of motion, exist the processor output control signal of turning on light directly to turn on light to light controling signal module, do not exist the human body of motion to start pyroelectric infrared sensor detection of dynamic, by processor, send and rotate control signal to step motor control module, step motor control module drive stepping motor, stepping motor drives pyroelectric infrared sensor to rotate, whether scanning there is static thermal source, do not exist static thermal source to turn off the light, exist static thermal source to turn on light and drive pyroelectric infrared sensor to carry out static state to quasi-thermal source direction by stepping motor and monitor, if action occurs static Looking Out Time endogenous pyrogen, think and have human body to exist, otherwise think to disturb thermal source, turn off light and enter program beginning cycle detection,
Light controling signal module, turns on light or turns off the light for receiving the light controling signal control of described processor output;
Step motor control module, for receiving the rotation control signal of described processor output, stepping motor driver module Driving Stepping Motor;
A stepping motor, for receiving the rotation control signal of described step motor control module output and driving the pyroelectric infrared sensor in the rotating shaft that is arranged on stepping motor to rotate according to described rotation control signal;
A pyroelectric infrared sensor, for surveying thermal source signal, and sends to processor by the information of obtaining, and processor is controlled the output of light controling signal module and turned on light or close modulating signal.
Outstanding advantages of the present invention is: in this device, be provided with stepping motor, be used for rotating pyroelectric infrared sensor motion, result from the relative motion of thermal source, guarantee to detect the existence of thermal source, there is circuit for controlling motor to monitor so that sensor alignment detects the direction of thermal source, kind interference such as () human body or hot water cup radiators that detects thermal source, by the Based Intelligent Control of program, has the discrimination higher to the Code in Hazardous Special Locations human body in library, classroom.Because mechanism is by program control, the stepping motor angle of can regulating the speed, forward reversion, transducer rotates to control flexibly and easily realizes, and does not need complicated mechanical structure.
In this device, pyroelectric infrared sensor is arranged in the rotating shaft of stepping motor, under the control of processor, rotate pyroelectric infrared sensor, can identify static thermal source, intelligent decision through program, can identify thermal source is human body or interference, has improved greatly human body recognition correct rate.
