Abstract
The invention discloses a kind of air conditioning control method, it can be by the way that the center position of human body heat source region in adjacent twice sweep be compared, to judge whether sleeper stands up behavior, when sleeper stands up behavior, air-conditioning reduces design temperature, sleeper is comfortably slept.
Description
Technical field
The present invention relates to a kind of air conditioning control method, more particularly to a kind of it can detect whether sleeper is constantly standing up
Air conditioning control method.
Background technology
Air-conditioning is opened at night during sleep, and human body enters after sleep state, if air-conditioning design temperature is too high, it will so that
Temperature is too high in room, it will so that human body is uncomfortable, people can constantly be stood up, it will the sleep quality of influence people.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of air conditioning control method, and it can constantly enter in sleeper
Air-conditioning design temperature is adjusted when row is stood up, to cause human body sensory comfortable.
In order to solve the above technical problems, the air conditioning control method that the present invention is provided, comprises the following steps：
(1), by the whole room of infrared sensor array timing scan on air-conditioning, each infrared sensor array scanning
When obtain the temperature data in whole room；
(2), temperature data is transferred to processor in real time and handled by infrared sensor array, constantly forms array of heat sources
Image；
(3), in the array of heat sources image that any single pass of infrared sensor array is formed, Studies of Human Body Heat is identified
Source region, then in the adjacent twice sweep of infrared sensor array, judges human body heat source region in array of heat sources image
Center position whether be moved, in this way, then judge sleeper stand up once, if not, showing that sleeper does not turn over
Body；
(4) if, sleeper stands up number of times more than X times in predetermined time period A, judge sleeper turned over constantly
Body, now reduces air-conditioning design temperature Y degree；
The method of identification human body heat source region is as follows in described step (3)：
When infrared sensor array is scanned every time, the present image for scanning formed is compared with background image,
The temperature difference is more than or equal to the regional determination behaviour body heat source region that 3 degree of array point is constituted, and the temperature difference is more than 1 degree of battle array less than 3 degree
The constituted regional determination of row point is alternative area, if the central point of alternative area is moved in the time span of Z minutes
It is dynamic, then judge alternative area behaviour body heat source region；
The establishing method of above-mentioned background image is as follows：
In infrared sensor array first scan, the temperature value of each array point in formed present image will be scanned
, should if the current temperature value of array point is more than the mean temperature of present image compared with the mean temperature of present image
The ambient temperature value value of array point is the mean temperature of present image, if the current temperature value of array point is less than or equal to currently
The average temperature value of image, then the ambient temperature value value of the array point is the current temperature value of the array point, sets each successively
The ambient temperature value of individual array point, to constitute background image；
In the non-first scan of infrared sensor array, the temperature of each array point in formed present image will be scanned
The temperature value of value array point corresponding with the image that preceding single pass is formed is compared, if the Current Temperatures of array point
Value is more than the ambient temperature value value of the temperature value, then the array point of corresponding array point in the image that preceding single pass is formed
The temperature value of corresponding array point in the image formed by preceding single pass, if the current temperature value of array point is less than or equal to
The temperature value of corresponding array point in the image that preceding single pass is formed, then the ambient temperature value value of the array point is the battle array
The current temperature value of point is arranged, the ambient temperature value of each array point is set successively, to constitute background image.
After above method, the present invention compared with prior art, has the following advantages that：
The present invention can be by the way that the center position of human body heat source region in adjacent twice sweep be compared, to sentence
Whether disconnected sleeper stands up behavior, when sleeper is constantly stood up, then shows that temperature is too high in room, allows sleeper
Feel hotter, now air-conditioning reduces design temperature, so that sleeper is comfortable on, sleeper is comfortably slept.
