Description
Technical field
The present invention relates to a kind of classroom demographics pick-up unit and detection method thereof based on infrared sensor of the human body, belong to the observation and control technology field, be fit to the public arena to statistics and the detection of certain area number, realize the monitoring relevant with number.
Background technology
Energy problem and environmental problem are the significant problems that human society is faced always, particularly to 21st century, the requirement that reduces the energy and protection of the environment have more been become the most important thing of national long-run development, and China also proposes the call of " energy-saving and emission-reduction ".And in numerous energy problems, the shortage of electric energy is one of important energy source problem of constraint economic development and people's lives.
It is reported, the energy resource consumption that is used for illumination accounts for the 20%-60% of whole office block energy resource consumption, the control effect that how much depends on to a great extent illumination of this part energy consumption.Deciding classroom bright light number by statistical number of person is an important aspect that classroom illumination is energy-conservation.
There is now kinds of schemes to can be used to calculating number of people in classroom: such as " a kind of automatically device of calculating number of people in classroom " (200920086234) of Ma Junwei etc., the mode of swiping the card with novel human-body emission receiving sensor and campus card counts on the class number, the method detects accurately, be conducive to the data centralization management, but can cause the classmate to form because swiping the card during the classroom in turnover blocks up, may cause and be late for class, card is lost and can not be entered the classroom or affect statistical accuracy if What is more, entering so swipe the card to be applicable to minority work office, and the public arena large for this flow of the people in classroom then can not be suitable for; The peace of School of Information Technology of university of name family of central authorities, " design of mobile personnel's number system and application---the design of classroom counter for number of people " of Yang Kaitao etc. (natural science newspaper, 2009.18(3)), it is to use photoelectric sensor, radio receiving transmitting module, Single Chip Microcomputer (SCM) system, serial ports transmission channel and PC VB interface form, by entrance and exit in each classroom photoelectric sensor is installed, each classroom is come number is added up by an AT89C51 Single Chip Microcomputer (SCM) system, be sent to PC by wireless transmit/receive units again, by the VB interface number of whole teaching building is shown online at last, be convenient to the management to whole teaching building, but photoelectric sensor be subject to many people when passing in and out simultaneously light stop and personnel in the entrance in classroom and exit the disturbing effect such as movable, cause personnel to pass in and out the detection statistics poor accuracy; Patent " based on number detection system and the method for video monitoring " (publication number CN200810118192.0) and for example, image based on the shooting of video monitoring camera, number in the real-time statistics video monitoring scene, system is each two field picture of receiver, video monitoring camera output successively, and image carried out analyzing and processing, finally by the computer statistics number, the method is very high for the resolution requirement of video monitor, also to constantly monitor the classroom simultaneously, so not only do not play energy-conservation effect, but also than originally having consumed a lot of electricity, some is lost more than gain more.
When above detection method is applied in the classroom demographics, therefore the problem such as exist to use that inconvenience, statistical accuracy are poor, system complex and energy-saving effect are poor is badly in need of a kind of easy to use, efficiently and more pick-up unit and the method for the classroom demographics of hommization now.
Summary of the invention
Use inconvenience, the statistical accuracy that the object of the invention is to overcome existing classroom turnover number detection method is poor, system complex and the poor deficiency of energy-saving effect, a kind of classroom demographics pick-up unit and method based on infrared sensor of the human body is provided, by the statistics to number in the classroom, and then in the control classroom bright light the small cup number, to reach energy-conservation effect.
The solution of the present invention is:
A kind of classroom demographics pick-up unit based on infrared sensor of the human body, comprise two infrared sensor of the human bodies, two casings and a wireless singlechip application system, two infrared sensor of the human bodies are installed in respectively in described two casings, the wireless singlechip application system is installed in one of them casing, two casings connect by wire, casing upper surface is provided with for the fixed orifice of installing, infrared sensor of the human body over against casing housing lower surface be provided with the crack.
