Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
Any modification, equivalent and improvement made within spirit of the present utility model and principle etc., broadly falls into this utility model
The scope of protection.
Infrared light curtain is operated in scan mode, and one first transmitting tube sends light pulse and corresponding reception pipe is sought simultaneously
Look for this pulse, complete the scanning of a light path after finding, turn next to down a pair corresponding transmitting tube and reception pipe, until
All of scanning all completes.After the completion of a cycle scanning, which light path thang-kng is system record, and which light path is blocked, such as
Fruit testee dimensional accuracy is high, and the speed of object movement is fast, then need the scanning speed of light curtain quickly, such as in vehicle external profile
In detection process, if the movement velocity of automobile is 5.4km/h, accuracy of detection is 30mm, then need Measuring light screen light distance between axles
It is 7.5mm, below scanning speed every optical axis 40us, the detecting distance of light curtain is not less than 6 meters.
As shown in figure 1, being the system architecture diagram of an embodiment, the present embodiment at least includes a pair of light curtain, each pair light
Curtain includes transmitting group and reception group, and transmitting group includes multistage transmitting terminal and emission control module, reception group include multistage receiving terminal,
Receive control module, data acquisition module data processing module, multistage transmitting terminal connects emission control module, multistage receiving terminal
Connect and receive control module, receive control module and connect data acquisition module data processing module；Emission control module controls
The work of transmitting terminal, receives the work that control module controls receiving terminal, receives control module and connects data acquisition module data
Processing module, the signal transmission that receiving terminal is received is to data acquisition module data processing module；
Every section of transmitting terminal is made up of multiple infrared transmitting tubes, and every section of receiving terminal is made up of multiple infrared receiving tubes, sends out for every section
The quantity penetrating the infrared transmitting tube at end is identical, and the quantity of the infrared receiving tube of every section of receiving terminal is identical；Infrared transmitting tube and infrared
Reception pipe corresponds, and infrared receiving tube is a kind of diode of infrared ray triggering, and reception pipe triggers, and produces change in voltage, electricity
Road carries out data acquisition data process to reception pipe output signal, can realize the safety prison to detection zone using this principle
Survey and the mensure of dimension of object.
Connect I/O line synchro between emission control module and reception control module, make one-to-one transmitting tube and reception
Pipe opens and closes simultaneously；Because infrared light spot is larger, transmitting tube sends a pulse hot spot, may multiple reception pipes can be simultaneously received
Infrared signal, can cause to report by mistake, therefore adopt I/0 line synchro, when each transmitting tube sends infrared signal, only infrared with transmitting
The corresponding reception pipe of transmitting tube of signal just can be opened, and just can transfer data to data acquisition module data processing module；
As shown in Fig. 2 the scan mode figure of a pair of light curtain for an embodiment, the control multistage transmitting of emission control module
End 1 is scanned simultaneously, and the transmitting tube 3 in each section of independent transmitting terminal 1 is connected in turn in order, each transmitting tube
1 is launched in order, and corresponding receiving terminal 2 is received.A pair of transmit-receive tube completes then to go to down after transmitting receives
A pair, sequentially carry out, until last completes transmitting reception to transmit-receive tube then completes a wheel scan.Emission control module
When sending command request transmitting terminal 1 work, first infrared transmitting tube 1 at first paragraph infrared emission end 1 sends infrared ray, simultaneously
First infrared transmitting tube 1 at every section of infrared emission end 1 all can send infrared ray, the like it is possible to realize multistage infrared
Transmitting terminal 1 launches infrared ray simultaneously.Due to having I/O line synchro between emission control module and reception control module, therefore launch
Pipe 3 send ultrared simultaneously, reception pipe 4 corresponding with it is also at opening receiving infrared-ray, does not result in wrong report, can
To realize the multistage infrared emission end 1 in a pair of light curtain and multistage infrared receiver end 2 is scanned and received simultaneously.For detection motion
Object expand sweep limitss, save sweep time, scanning accuracy improves.
The scheme of further optimization, light curtain logarithm can extend, during more than or equal to two pairs, light curtain between connect I/O
Line synchro, makes multipair light curtain synchronous scanning, in actual applications, the limited length of a pair of infrared light curtain, specifically should can not meet
Used time, can in addition increase by a pair or some to light curtain, light curtain to and light curtain between be also reserved with I/O line synchro, light curtain to
Light curtain between I/O line synchro guarantee multipair light curtain between synchronous scanning.
The scheme of further optimization, transmitting tube and reception pipe correspond, and are equidistantly placed in both sides respectively, in
Between formed light curtain.
The scheme of further optimization, installs safety alarm module, Dynamic IR measurement grating device can in systems
To use as safe light curtain, once the infrared ray of any bar light path is blocked in measurement range, it is issued by safety alarm, remind
With the presence of unsafe factor, and the overall dimensions of unsafe factor can be measured.
Infrared survey grating operation state, the spacing simultaneously launching ultrared transmitting tube is more than the size of infrared light spot,
Although there being multiple reception pipes to receive infrared signal at the same time, the spacing of the reception pipe simultaneously opened is more than infrared light spot size, because
It does not interfere with each other between this reception pipe opened, wrong report phenomenon will not be formed.
A pair of light curtain is divided into multistage transmitting terminal and receiving terminal by one embodiment of this utility model, by a pair of emission control mould
Block and reception control module are controlled, and every section of length is 120-6500 millimeter, and the spacing between every section of internal tube is 7.5
～60 millimeters, the spacing between reception pipe is also 7.5～60 millimeters, and a pair of light curtain is divided into 1～16 section, with processor technology
Raising, segments can also improve, and such as can reach 96 using the processor segmentation number of 16 cores.Multistage transmitting terminal, reception
End scanning simultaneously is so that have two or more transmitting tubes and reception pipe being scanned, sweep time reduces, and sweeps simultaneously
Retouch speed to improve.For moving object measurement, it is greatly improved scanning accuracy.A pair of light curtain length is 120～6500 millimeters,
Coverage can not meet when needing, it is possible to use multipair light curtain, between multipair light curtain also using I/O line synchro connect it is ensured that
The synchronization of multipair light curtain, the quantity of multipair light curtain does not limit.Therefore, all of section（Section including different light curtain centerings）All protect
It is synchronous for having demonstrate,proved, it is to avoid the interfering of light.
