Accompanying drawing explanation
Fig. 1 is light veil type vehicle external profile size detecting device schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Fig. 1 is light veil type vehicle external profile size detecting device schematic diagram, including TCH test channel F, portal frame H, wheelbase measuring unit, survey high measurement unit, the wide measuring unit of survey, described portal frame H is arranged in the middle part of TCH test channel F, described wheelbase measuring unit includes many group wheelbase infrared tubes, wheelbase infrared tube is arranged on respectively at equal intervals slightly above TCH test channel ground both sides C1 and C2, is connected with wheelbase panel；Described survey high measurement unit includes many groups and surveys high IR to pipe, surveys high IR and is arranged on portal frame two heel post B1 and B2 respectively at equal intervals to pipe, is connected with surveying high panel；Described width measuring unit of surveying includes many wide infrared tubes of group survey, and the wide infrared tube of survey is arranged on the light curtain hookup wire A2 on portal frame crossbeam A1 and the TCH test channel parallel with portal frame crossbeam respectively at equal intervals, is connected with surveying width panel；Wheelbase panel, survey high panel and be connected with master controller with survey width panel.
Including wheelbase data processing unit on master controller, altimetry data process ing unit, width data processing unit and profile set up unit, and the photoelectric characteristic utilizing infrared photocell is: receiving head and sense the infrared ray that transmitting tube sends, it is output as low level；As Infrared is blocked, then output becomes high level.In vehicular motion to be measured, during the different photoelectricity of occlusion, receive pipe level and change, survey wide panel and be connected；Wheelbase panel just can obtain the moment corresponding when level changes with surveying high panel, the system positional information according to temporal information and different photocells, so that it may calculate vehicle average speed in whole surveying range and relative position.nullWheelbase data processing unit according to wheelbase panel collect not different wheelbase infrared tubes in the same time by the data of occlusion to be measured calculates and records vehicle to be measured traveling speed and not wheelbase in the same time，The data of pipe are calculated and record not height of car in the same time according to the high IR of surveying surveying high panel and collecting not the extreme higher position that is blocked on portal frame in the same time by altimetry data process ing unit，Survey wide data processing unit and calculate and record not vehicle width in the same time according to the data surveying wide infrared tube of position surveying wide panel and collecting not the widest both sides being blocked on portal frame in the same time，Profile set up unit according to collect to be tested measure advance speed、Not wheelbase in the same time、Not height of car in the same time and not vehicle width in the same time treat the outline of measuring car and be modeled，Calculate the contour dimension obtaining vehicle to be measured.
Owing to this detecting device is provided with multiple infrared tube, and in order to improve its measuring accuracy, to tube pitch from close to, therefore it is easy to occur the mistake of phase adjacency pair pipe generation error detection or judgement, in order to improve the accuracy of test further, wheelbase infrared tube, survey wide infrared tube and survey the high IR transmitting infrared light to the transmitting tube of the infrared tube on pipe all with different coding numerals, the data processing circuit of corresponding infrared receiving tube is designed with decoder module, receiving terminal only receives the infrared signal of the coding numeral being consistent with this infrared receiving tube, just confirm this to infrared tube not by occlusion to be measured.
Above disclosed it is only an embodiment of the present invention, certainly the interest field of basis can not be limited with this, one of ordinary skill in the art will appreciate that all or part of flow process realizing above-described embodiment, and according to the equivalent variations that the claims in the present invention are made, still fall within the scope that the present invention contains.
