Technical field
The present invention relates to a kind of light veil type passenger flow counting device, be meant intelligentized light veil type passenger flow counting device that directly can sense data especially.
Background technology
At present, at public transit vehicle, some public places such as supermarket, need add up turnover personnel's quantity, under the relatively backward situation of initial science and technology, just by manually adding up, its workload is very large, and, time one is long, produce visual fatigue and also can make mistakes easily, make that last data of adding up are unreliable, afterwards along with scientifically constantly progress, video camera arises, people take turnover personnel's situation by video camera and note, and are last, again the result who notes according to shot by camera, come out by complicate statistics, this mode, though compared with statistical at first improvement has definitely been arranged,, still need personnel to add up at last, still very inconvenient.Along with scientific-technical progress, the infrared passenger flow counting device of correlation begins to come into operation, because there is the technology limitation in this passenger flow counting device, can't detect the situation that many people pass in and out simultaneously, can't use under the current places with dense environment of personnel.
Summary of the invention
Purpose of the present invention: in order to overcome the defective of existing infrared passenger flow counting device technology, the invention provides a kind of can count automatically personnel into and out of quantity and overcome correlation mode infrared counting device and can't add up the novel light veil type passenger flow counting device that many people pass in and out defective simultaneously.
Technical scheme of the present invention: a kind of light veil type passenger flow counting device, it is characterized in that: include at least two group signal detection systems and passenger flow algorithm central processing unit system, the group of described signal detection system with the group between become adjacent setting, described every group of signal detection system includes the detecting signal unit that two row are set up in parallel, described detecting signal unit includes the infrared signal transmitter module, infrared signal receiver module and passage scan process module, detecting signal unit in the described signal detection system is worked successively, described passenger flow algorithm central processing unit system is used to handle the signal that is produced by described signal detection system, unify to handle according to the information of many groups signal feedback, described passenger flow algorithm central processing unit system comprises communication module, the passenger flow APU, output module, passenger flow data memory I/O load module.
Adopt technique scheme, advance as personnel, when going out, personnel are in passing light veil type passenger flow counting device process, personnel must be by the infrared signal sensing range of described a certain group of detecting unit, when having personnel to exist in the sensing range of detecting signal unit, just can produce and destroy original infrared signal intensity, the infrared signal intensity that two receiver modules arranged side by side can receive successively changes, receiver module is given described passenger flow algorithm central processing unit system by the I/O outputs level signals, passenger flow algorithm central processing unit system can calculate the information that produces the current direction of personnel according to the mistiming and the level amount of the level signal generation of two receiver modules, passage rate and personnel's elevation information, after personnel pass through light veil type passenger flow counting device fully, described two signal receiving modules collect original signal successively, compare processing by described passenger flow algorithm central processing unit system by organizing detecting units with other, produce volume of the flow of passengers data at last, if both direction information is identical, described central processing module can obtain personnel according to directional information and advance, the direction that goes out, if both direction information difference, think that then these personnel do not finish into, go out action, do not count.The technology that adopts detecting signal unit to work successively in addition so can the phase mutual interference between each detecting signal unit.
Further technical scheme of the present invention is: the processing module in described every group of signal detection system includes initialize signal register, signal receiving register, passage scanning communication interface and is used for the comparison initialize signal and the signal comparator of received signal power; The described detecting signal unit of respectively organizing in the signal detection system connects successively by scan interface, constitute the scanning communication loop, the detecting signal unit in every group of signal detection system starts the detecting signal unit work in next group signal detection system after hours automatically; Described detecting signal unit is aggregated into passenger flow algorithm central processing unit system according to the detected level information of current state, carry out the unified processing of dot matrix algorithm by passenger flow algorithm central processing unit system, bear results and carry out data transmission by communication module and third party device.
Adopt above-mentioned further scheme, make whole arrangement of this product rationally count better effects if.
Below in conjunction with accompanying drawing the present invention is described further.
