Description
Technical field
The utility model relates to screening machine technical fields, especially for the screening machine for requiring accurate counting, specifically one
The device of the kind infrared double light barrier accurate countings of screening machine.
Background technique
Safety check machine equipment is generally positioned at station, scenic spot, conference and exhibition center et al. traffic-intensive and needs the public affairs of stringent safety check
Place altogether, to find dangerous goods in advance and exclude hidden danger.The feature that existing screening machine usually utilizes X-ray penetrability strong,
Emit X-ray by point light source, X-ray is limited in angle as 80 degree of a covering of the fan by collimator, after transparent objects, is declined
X-ray after subtracting is received by L-type detector array, and signal is amplified through amplifying circuit, digital signal is then converted into, finally shows
Show system over the display.
In normal packet excessively, the luggage parcel for encountering certain shapes counts existing safety check machine equipment more there are counting loss,
The shortcomings that.Cause some scenes for needing accurate counting such as scenic spot, express delivery site often can not accurately calculate packet quantity, causes
It manages not in place.
Utility model content
It is not allowed the technical problem to be solved by the utility model is to overcoming and being counted present in the existing package counting of screening machine
True problem provides a kind of method of energy accurate counting.
A kind of device of infrared double light barrier accurate countings of screening machine is provided, includes single chip control module and infrared light barrier
Module, the one-chip computer module and the infrared light barrier module are separately connected.
Whether infrared light barrier module has package on belt in the process of running for detecting screening machine, when package block it is infrared
When connection between light barrier transmitting terminal and receiving end, this connected state for organizing infrared light barrier is cut off；
Single chip control module is used to receive the signal of infrared light barrier module transmitting, judges the connected state of infrared light barrier,
And it controls package and counts.
Further, the infrared light barrier module includes transmitting terminal and receiving end, and the transmitting terminal is mounted on correspondence
The opposite side of receiving end；
Further, at least two groups of the infrared light barrier module, the first infrared light barrier module transmitting terminal and second red
Outer light barrier module transmitting terminal intersects installation, is located at screening machine inner wall opposite side, and the first infrared light barrier module transmitting terminal and the
The installation position of two infrared light barrier module transmitting terminals is equipped with certain vertical range.
The purpose that two groups of infrared light barriers of height are arranged is to prevent the package seldom with belt contacts face from causing to leak when passing through
It counts and wraps up and belt contacts face discontinuously leads to count more.
Further, the receiving end of the infrared light barrier module is connect with the single chip control module by conducting wire, will
The signal received passes to single chip control module.
Further, when the single chip control module detects that two groups of light barrier modules are no less than one group and are not in connected state
It when state, is judged as having new package on roller, counts and add one.
The transmitting terminal of the light barrier module is connected to power supply board, is powered by power supply board.
The utility model is beneficial in that cost is few, and structure is simple, and can effectively solve package of different shapes causes
Counting loss or the problem of counting, provide the user with reliable statistical data more.
Detailed description of the invention
Fig. 1 is the scheme of installation of a preferred embodiment of the utility model.
Specific embodiment
Below in conjunction with attached drawing and specific embodiment, the technical solution of the utility model is further described in detail:
A kind of device of infrared double light barrier accurate countings of screening machine is provided, includes single chip control module and infrared light barrier
Module, one-chip computer module are separately connected with infrared light barrier module.
Intersect two groups of infrared light barrier modules of installation in screening machine entrance, first group infrared light barrier transmitting terminal 10 is mounted on
The upper end of screening machine inner left wall, second group infrared light barrier transmitting terminal 20 are mounted on the lower end of inner wall on the right side of screening machine, and first group
Vertical range between infrared light barrier transmitting terminal and second group infrared light barrier transmitting terminal is 50 centimetres；First infrared light barrier receiving end
30 with the second infrared light barrier receiving end 40 be separately mounted to corresponding infrared light barrier transmitting terminal to side position.
Infrared light barrier receiving end is connected on the I/O pin of single chip control module 50 by conducting wire, the signal that will be received
Pass to single chip control module.
When screening machine works, the signal received is passed to single chip control module, works as list by the starting of infrared light barrier module
When piece machine examination measures two groups of infrared light barriers and is no less than one group and is not in connected state, it is judged as having new package on roller, counts
Number plus one.
Particularly, infrared light barrier module is connected to power supply board, is powered by power supply board 60.
Above embodiments are only used for the explanation to the utility model, and the creation of the utility model is not limited in this implementation
Example, without prejudice under the utility model creative spirit, those skilled in the art can also make many same modifications
Or replacement, these same variation or replacement are all contained in the rights protection scope of the utility model.
