Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, the dynamic auto measurement mechanism of a kind of vehicle contour dimension, this device comprises digital measurement light curtain 1, signal processing module 2, data acquisition system (DAS) 3 and computer software processing module 4.Computer software processing module 4 can connect display and printer.
Digital measurement light curtain is used for height measurement, width measure and linear measure longimetry; Height measurement, width measure are connected by the signal processing module corresponding with it 2, data acquisition system (DAS) 3 respectively with linear measure longimetry.As shown in Figure 2, linear measure longimetry comprises digital measurement light curtain 5 and the infrared positioning switch 6 of correlation, the transmitting terminal 7 of the infrared positioning switch 6 of correlation and receiving end 8 relative installations, and be arranged on by equidistant arrangement and detect the both sides, track, as shown in Figure 3, width measure comprises digital measurement light curtain 5, the vertical transmitting terminal 10 of the light curtain of digital measurement light curtain 5 and the vertical receiving end 11 relative installations of light curtain, and by the equidistant transversely arranged upper and lower side position of detecting the track that is arranged on, as shown in Figure 4, highly measure and comprise digital measurement light curtain 5, the horizontal transmitting terminal 13 of the light curtain of digital measurement light curtain 5 and the horizontal receiving end 14 relative installations of light curtain, and by the equidistant both sides that are arranged on the detection track of vertically arranging.
1, organizes the infrared positioning switch of correlation, digital measurement light curtain survey vehicle length more
As shown in Figure 2, digital measurement light curtain 5 is made up of light curtain line transmitting terminal and light curtain line receiving end and is lined up several digital measurement light curtain linear arrays respectively, lie in a horizontal plane in and detect the left and right sides, track, the linear array direction is parallel with vehicle heading, and the spacing between every digital measurement light curtain line is 0.5-2cm.As shown in Figure 6, transmitting and receiving by signal processor of digital measurement light curtain controlled, signal processor is built-in with timesharing scanning electron control system, at any time the section, emission and the reception of digital measurement light curtain have only a pair of connection, and this method of sampling can make measured value accurately navigate to 5-10mm.
As shown in Figure 2, the transmitting terminal 7 of organizing the infrared positioning switch of correlation district and receiving end 8 are placed in the left and right sides of detecting the track respectively and by equidistant arrangement setting more, and are an angle of 90 degrees with vehicle 15 travel directions.Consider the different maximum length marginal positions of different vehicle 15, the transmitting terminal 7 of the infrared positioning switch 6 of correlation is placed into different height respectively with receiving end 8, and infrared positioning switch 6 spacings of adjacent two groups of correlations are less than the measurement length range of digital measurement light curtain 5.Here to the length of measuring vehicle 15 without limits, lengthen measurement range if desired, the group quantity that only needs to increase the infrared positioning switch 6 of correlation gets final product.The length of vehicle 15 can satisfy the requirement of the countries concerned's standards to not influence of measuring accuracy.
Adopt digital measurement light curtain and the infrared positioning switch 6 of many group correlations to add that the logical operation of software is achieved measuring vehicle 15 length, this kind method is measured not only precision height of vehicle commander, and has saved hardware cost to greatest extent.
2, digital measurement light curtain is surveyed vehicle width and height.
Width measure as shown in Figure 3, in the end positions up and down that detects the track digital measurement light curtain 5 is installed, digital measurement light curtain 5 is made of with the vertical receiving end 11 of light curtain the vertical transmitting terminal 10 of light curtain in pairs many, be arranged into linear array and place respectively, the spacing between the vertical transmitting terminal 10 of per two light curtains is the 5-10 millimeter.Digital measurement light curtain 5 adopts timesharing scanning, sending method, and mobile vehicle 15 width are measured.,, multiply by digital measurement light curtain and measure spacing through calculating the quantity that digital measurement light curtain is blocked by detecting in the track at vehicle 15, calculate the width value of vehicle 15.
Highly as shown in Figure 4, same,, be arranged into linear array and arrange respectively by the equidistant digital measurement light curtain 5 of vertically installing in the end positions that detects the track, the spacing between the horizontal transmitting terminal 13 of per two light curtains or the horizontal receiving end 14 of light curtain is the 5-10 millimeter.Digital measurement light curtain 5 same timesharing scanning, the sending methods of adopting are highly measured mobile vehicle 15.When vehicle 15 passed through to detect the track, the quantity that is blocked through calculating digital measurement light curtain multiply by digital measurement light curtain measurement spacing, calculates the height value of vehicle 15.
3, measuring method
Adopt the infrared positioning switch of many group correlations, DATA REASONING light curtain survey vehicle length, width, highly, gate high integrity data
As shown in Figure 5, by computer control and management whole measuring system.When measuring beginning, selftest module is started working, after various inspections are errorless, software sends sense command to vehicle 15, the infrared positioning switch 6 of many group correlations judges whether vehicle 15 enters measurement range (as shown in Figure 2, the infrared positioning switch 6 of many group correlations can be judged the direct of travel of vehicle 15 by software), if enter, then start the infrared positioning switch 6 of many group correlations, the digital measurement light curtain of detection width, detect the digital measurement light curtain of length and the digital measurement light curtain of detection height and start working, collection vehicle 15 is long, wide, the dynamic real time data of height and gate height.When if vehicle 15 heads enter the measurement length range of the digital measurement light curtain 5 that detects length, determine vehicle 15 head in-positions by the infrared positioning switch 6 of many groups correlation, vehicle 15 is measured length work and is finished; If vehicle 15 afterbodys cross the digital measurement light curtain 5 that detects length, then surveying work finishes.By data acquisition system (DAS) the data that collect are sent to computing machine by data communication protocol, again by sampled signal control module, sampled images filtering module, image modification module, 3-D view analog module, database memory module, data disaply moudle, finally draw the gabarit 3-D view of vehicle 15 and length, width, highly, gate high integrity data, simultaneously the data of measuring are deposited in the database.When detecting some special car 15, as the cement tub tank car etc., have partly that the profile geometric figure is circular shape, the 3-D view simulation softward can call in system, on computer screen, vehicle 15 profile three-dimensional picture, front, side, vertical view are revised.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
