Description
Technical field
The present invention relates to the data processing method of human body infrared temperature sensor, belong to the sensing data process field.
Background technology
Device as human body sensing, pyroelectric infrared sensor, microwave Doppler sensor are the standard configurations of carrying out lighting energy saving control and building energy saving control now, but these two kinds of sensors all are the human bodies that can only detect in the motion, do not have power of test for actionless human body, so its service behaviour and range of application are very restricted all.
In order to address this problem, there is producer to release the human body infrared temperature sensor that can detect static human.This sensor is that the infra-red radiation in the surveyed area is imaged on the corresponding pixel, and temperature is more high, and the output data are more big.From data matrix, extract temperature data, if these data are mated with human body temperature then can be judged that the someone exists.But the human body infrared temperature sensor adopts pixel matrix structure, the part of the corresponding surveyed area of each pixel.If human body has just in time occupied a complete pixel, then this pixel is exported human body temperature value accurately; But work as the centre position that human body is in the region unit of a plurality of pixel correspondences, perhaps owing to the distance reason, the projection of human body only accounts for the part position of pixel, therefore exports the temperature value that data do not reach human body, brings difficulty to human detection.
Summary of the invention
The objective of the invention is in order to address the above problem, adopt energy conservation theory, to carry out the data reduction above the pixel data of ambient temperature by data analysis technique, and calculate to cause the object area size of this variations in temperature, thereby judge whether that human body exists.

Implementing good effect of the present invention is: can judge 1, whether static state or dynamic human body exist; 2, under the complex environment of reality, can in " hidden " data message, extract the temperature data of human body, realize the detection of human body.
Description of drawings
Fig. 1 is the sketch map of human body infrared temperature sensor;
Fig. 2 is the flow chart of data processing method.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1-2, the data processing method of human body infrared temperature sensor, the lens 1 of optical focus are carried out in the setting of described human body infrared temperature sensor, and infrared energy is converted to the pel array 2 of the signal of telecommunication and the electrical signal conversion of described picture element matrix output is become the go forward side by side electronic processing circuit of line output of digital signal.Described lens 1 focus on the infra-red radiation that the object in the surveyed area sends, and project on the described picture element matrix 2; Described picture element matrix 2 converts the infrared energy of input to the signal of telecommunication and output, and the described signal of telecommunication is analogue signal, and its amplitude size is directly proportional with the infrared energy of input; Described electronic processing circuit amplifies the analogue signal of described picture element matrix 2 outputs, and converts the digital signal line output of going forward side by side to.
