The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of strong infrared of cost-effective, expansibility
Array demographic method.
The purpose of the present invention is achieved through the following technical solutions：Infrared array demographic method, it is included just
Beginning demographics step and number of people entering statistic procedure, described demographics step include following sub-step：
S11：The number in each room is united by the infrared sensor array being arranged on the roof in multiple rooms
Meter, including following sub-step：
S111:The region for gathering image is divided into 8*8 64 zonules by infrared sensor array；
S112：To each zonule measurement temperature；
S113：The number in region is judged according to the temperature change in zonule；
S12：The number that each room counts on is collected, sent by concentrator to Surveillance center, including it is following
Sub-step：
S121：The initial demographics data counted on are sent into concentrator by each room；
S122：Initial demographics data are sent into Surveillance center by concentrator；
S123：Surveillance center receives the initial demographics data in each room, and is added to obtain total initial number；
Described number of people entering statistic procedure includes following sub-step：
S21：By the infrared sensor array being arranged on the door in multiple rooms, gather through door temperature change stream and
Its direction, and the statistics entered and left to the number of each：When someone passes in and out room, infrared array sensing
Device can detect temperature change stream in monitored area：
（1）If the direction of temperature change stream is in door, having counted on a people outdoors and entered room；
（2）If the direction of temperature change stream is to be withdrawn from a room out of door to outdoors, having counted on a people；
S22：The number for the inlet/outlet that each room is counted on is collected, and is sent by concentrator to Surveillance center,
Including following sub-step：
S221：The demographics data of the disengaging door counted on are sent into concentrator by each room；
S222：The demographics data for passing in and out door are sent into Surveillance center by concentrator；
S223：Surveillance center receives the demographics data in the disengaging room in each room, is obtained according to step S123
The initial demographics data in each room carry out corresponding data manipulation.
Described step S112 includes following sub-step：
S1121：Image acquisition units gather image；
S1122：The image collected feeding amplifier is amplified operation；
S1123：Data after amplification are sent into Analog-digital Converter module, carry out AD operations；
S1124：Data signal feeding high speed image APU is entered to the measurement of trip temperature.
Described concentrator is RS485 concentrators.
The beneficial effects of the invention are as follows：（1）Infrared sensor array can capture 64 width two-dimensional pixel pictures at once, significantly simple
Change integrated thermal imaging system, so that by price maintenance in high-volume, the acceptable scope of inexpensive application field, cost performance
It is high；（2）Initial demographics data and disengaging door demographics data are separated, reduce the infrared battle array being arranged in room
The data acquisition density of sensor, adds service life；（3）Suitable for the situation of a variety of demographics, including indoor people
Situations such as number statistics, operation demographics and cubicle demographics of commercial building, there is the advantages of expansibility is strong.
Brief description of the drawings
Fig. 1 is the inventive method flow chart；
Fig. 2 is schematic diagram of the embodiment of the present invention.
Embodiment
Technical scheme is described in further detail below in conjunction with the accompanying drawings：As shown in figure 1, the present embodiment includes six
The roof of one big room of six cubicles of cubicle and connection, six cubicles and a big room is provided with infrared array
Sensor, infrared sensor array is provided with six six doors between cubicle and big room, is set on the gate of big room
It is equipped with infrared sensor array.
Collection for primary data, seven infrared sensor arrays for being arranged at roof are carried out to the number in each room
Collection, Surveillance center is output to by concentrator and is monitored and collects.Data acquisition for passing in and out door, on each door
Infrared sensor array is acquired to temperature change stream：
（1）If someone goes to big room from cubicle 1, the infrared sensor array on cubicle 1 can be collected from door
Temperature change stream outdoors is inside moved to, then the number for counting cubicle 1 subtracts 1, and the number of big room adds 1, and total number of persons is constant；
（2）If someone goes to cubicle 5 from big room, the infrared sensor array on cubicle 5 can be collected from door
The outer temperature change stream being moved in door, the then number for counting cubicle 5 add 1, and the number of big room subtracts 1, and total number of persons is constant；
（3）If someone leaves big room from gate, the infrared sensor array on the gate of big room can collect from
Temperature change stream outdoors is moved in door, then the number for counting big room subtracts 1, and total number of persons subtracts 1.
If only with the infrared sensor array for being arranged at roof, when the people in room does not go out room i.e. not to demographics
Change, but infrared sensor array can carry out repeated acquisition from start to finish to data, data acquisition amount is high.And pass through
The infrared sensor array being arranged on door, due to data acquisition variation be only when there are personnel's access door,
Other situation data acquisitions are essentially identical, greatly reduce the amount of Data acquisition and issuance.
