Embodiment
Below in conjunction with accompanying drawing 1-6 embodiment of the present utility model is made a detailed explanation.
The dynamic auto measuring system of vehicle contour dimension as shown in Figure 1 comprises distance measuring sensor group 1, signal processing module 2, computer data acquisition system 3, computer software processing module 4.Distance measuring sensor group 1 comprises height survey sensor, width measure sensor and length measuring sensor.Height survey sensor, width measure sensor and length measuring sensor are respectively by being connected with its corresponding signal processing module 2, computer data acquisition system 3.The software processing module 4 that computer data acquisition system 3 connects on the computing machine.Length measuring sensor adopts infrared light curtain sensor 5 and the infrared positioning switch 7 of many group one lines.The width measure sensor can adopt laser scanning system 8.The height survey sensor can adopt laser scanning system 8 or infrared light curtain sensor 5.
1, organizes the infrared positioning switch 7 of a line, infrared light curtain sensor 5 survey vehicles 6 length more
(1) as shown in Figure 2, infrared light curtain sensor 5 is made up of infrared transmitting tube and receiving tube and is lined up several linear arrays respectively, lies in a horizontal plane in to detect the left and right sides, track, and the linear array direction is parallel with vehicle heading.The infrared transmitting tube of each linear array or the tube pitch of receiving tube are 0.5-2cm.As shown in Figure 5, transmitting and receiving by single-chip microcomputer of infrared light curtain sensor 5 controlled, single-chip microcomputer is built-in with timesharing scanning electron control system, at any time the section, the emission of infrared light curtain sensor 5 and reception have only a pair of connection, this method of sampling can make measured value accurately navigate to 10mm, even littler.
As shown in Figure 2, organize the transmitting terminal of the infrared positioning switch 7 of a line and receiving end more and be placed in the left and right sides of detecting the track respectively and place, and be an angle of 90 degrees with vehicle 6 travel directions by equidistant, equidistant arrangement.Consider the different maximum length marginal positions of different vehicle 6, the transmitting terminal of the infrared positioning switch 7 of a line is placed into different height respectively with receiving end, and infrared positioning switch 7 spacings of adjacent two group of one line are less than the measurement length range of infrared light curtain sensor 5.Here without limits to the length of measuring vehicle 6, the measurement range that extends if desired, the quantity that only needs to increase by 7 groups of the infrared positioning switches of a line gets final product.The length of vehicle 6 can satisfy the requirement of the countries concerned's standards to not influence of measuring accuracy.
Vehicle 6 is in the process of advancing, the headstock partial occlusion is lived infrared light curtain sensor 5, when the tailstock enters the measurement length range of the infrared positioning switch group 7 of a line simultaneously, computer calculates by headstock shield portions infrared light curtain sensor 5 power valves and the paired quantity of receiving tube, multiply by the spacing of infrared tube, add distance between infrared positioning switch 7 of a line that certain group is blocked by the tailstock and the infrared light curtain sensor 5, finally calculate the length value of vehicle 6.In addition, infrared light curtain sensor 5 also has the function of judging vehicle 6 travel directions.
Adopt infrared light curtain sensor 5 and the infrared positioning switch 7 of many group one lines to add that the logical operation of software is achieved measuring vehicle 6 length, this kind method is measured not only precision height of vehicle commander, and has saved hardware cost to greatest extent.
2, the composite measurement of laser scanning system 8 pairs of vehicle 6 width, height and gate height
Adopt laser scanning system 8 realize vehicle 6 width, highly, the composite measurement of gate height.Laser scanning system 8 is installed in the top 4-6 rice height (as shown in Figure 3) overhead that detects the left and right sides, track, and scanning angle 9 is the 60-100 degree.In vehicle 6 advanced process, 2 laser scanning systems 8 were controlled by computing machine.The width of 8 pairs of vehicles 6 of laser scanning system, highly, the high degree in container hurdle carries out two-dimentional kinetic measurement.Vehicle 6 gabarits that laser scanning system 8 at first successively scans are to the relative distance of laser scanning system 8, by computer software calculate the width of vehicle 6 two dimensions, highly, the instantaneous dimensional data of gate height, adopt the timesharing method for scanning again, obtain width, height and the gate height value of each cutting branch aspect when vehicle 6 moved, combination is to vehicle 6 measurement of lengths simultaneously, by software processing, simulation and output vehicle 6 gabarit three-dimensional picture and dimensional datas.
The measurement of high-resolution laser scanning system 8 pairs of vehicle 6 width, height and gate height, this kind method is by the dynamic image treatment technology, depict the contour images on vehicle 6 surfaces, carry out data processing again, remove the influence of the factor such as Position indication lamp, rearview mirror of vehicle 6 to greatest extent, draw vehicle 6 real width, height and gate height dimension value.
3, measuring method
The infrared positioning switch 7 of many group one lines, infrared light curtain sensor 5 and laser scanning system 8 survey vehicles 6 length, width, highly, gate high integrity data
As shown in Figure 4, by PC computer control and management whole measuring system.When measuring beginning, the sensor selftest module is started working, after various sensors inspections are errorless, software sends sense command to vehicle 6, the infrared positioning switch 7 of many group one lines judges whether vehicle 6 enters measurement range (as shown in Figure 2, the infrared positioning switch 7 of many group one lines can be judged the direct of travel of vehicle 6 by software), if enter, then the infrared positioning switch 7 of startup many groups one lines, laser scanning system 8 are started working the dynamic real time data of collection vehicle 6 lengths and gate height.When if vehicle 6 heads enter the measurement length range of infrared light curtain sensor 5, determine vehicle 6 head in-positions by the many groups one infrared positioning switches 7 of line, vehicle 6 is measured length work and is finished; If vehicle 6 afterbodys cross laser scanning system 8, then surveying work finishes.By computer data acquisition system the data that collect are sent to PC by 100,000,000 netting twines, again by sampled signal control module, sampled images filtering module, image modification module, 3-D view analog module, database storing module, data disaply moudle, finally draw the gabarit 3-D view of vehicle 6 and length, width, highly, gate high integrity data, simultaneously the data of measuring are deposited in the database.When detecting some special car 6, 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 6 profile three-dimensional picture, front, side, vertical view is revised.
