Three-dimensional laser scanner is comprised of laser and ccd video camera, utilizes principle of triangulation to measure the three-D profile by lower vehicle.
Three-dimensional laser scanner is arranged on the both sides of under-vehicle, transfinite in measuring vehicle bottom, surveying high ccd video camera for one is arranged on car body top quite on a body side frame of height, and on the both sides, position a little more than camera, laser radar is installed, by Data fusion technique composite measurement middle part transfiniting and transfinite in top, by laser radar or measure light curtain and complete the end detection of transfiniting, by infrared tube, carried out the anticipation of transfiniting of Width.
The waveform that utilizes wheel cutting magnet steel to produce, start measuring system and make an uproar and finally by SCM program, calculate vehicle Negotiation speed by rectification, amplification, filter, utilization calculates lorry joint number to pipe, the meter joint speed measuring function of comprehensive number identification device, Comprehensive Control unit is given the object localization that transfinites, the floor light that utilizes HF lamp without electrodes to provide the pick up camera in the lower situation of equiluminous at night to measure, utilizes chequered with black and white background board to reduce the empty scape phenomenon of image measurement.
Vehicle operating ground safety detection device obtains vertical power and transverse force by two-dimentional plate type sensor, thereby obtain the derailment coefficients of lorry, obtaining gross vehicle weight in conjunction with shear force sensor, calculating overload of vehicle unbalance loading state in conjunction with car number identification system, utilize waveform analysis wheel flat situation.
The invention has the advantages that:
1. complete function.Each position of measuring vehicle transfinites comprehensively, can obtain again the security parameter of the ground detection such as the super unbalance loading of vehicle, flat scar, derailment coefficients, adopt three-dimensional laser scanner measurement bottom to transfinite, solve vehicle dead angle photogrammetric and that lidar measurement can not measure, make the present invention can measure whole positions of transfiniting.The safety detection part decapacitation of vehicle operating ground detects outside excess of export unbalance loading, simultaneously can be to the running state of vehicle is carried out to comprehensive evaluation.
2. precision is high, highly sensitive.Adopt mode measuring vehicle middle part and the bottom that image measurement is combined with laser radar to transfinite, data anastomosing algorithm takes into full account two kinds of mode merits and faultss, learn from other's strong points to offset one's weaknesses, take into account laser radar out of reach and high sensitivity that image measurement can reach, can measure the three-dimensional coordinate of the thing that transfinites again, thereby obtain the rank that transfinites that image measurement can not measure simultaneously.
3. energy-conservation.Intelligent light system, illumination is not enough and while sending a car, light just starts.Illuminating lamp adopts up-to-date green illumination---HF lamp without electrodes, and device illumination power consumption is down to 1320 watts from 5500 watts.
Accompanying drawing explanation
Fig. 1 is structure scheme of installation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1, when train is by magnet steel group (8), wheel cutting magnet steel produces electric signal, electric signal is received in Comprehensive Control unit (16), to power supply/electrical control subsystem (21), send each measuring system of signal enabling, when ambient light illumination is not enough, Comprehensive Control unit (16) sends signal enabling Lighting System, Comprehensive Control unit (16) calculate car joint according to meter joint to the signal of pipe (6) simultaneously, utilize same wheel to calculate the speed of a motor vehicle in the time difference of the magnet steel generation signal of permanent distance, finally export serial data and pass to industrial computer (18) and the workstation (19) in on-the-spot rack, by optical transmitter and receiver (20), pass to each microcomputer of Central Control Room simultaneously.The High Speed Serial capture card of workstation (19) and image pick-up card by laser radar (3), survey high pick up camera (2), the information acquisition of surveying wide pick up camera (4) is to computing machine, serial data in conjunction with Comprehensive Control unit (16), by corresponding Algorithm Analysis, parsing, calculating, finally draw the information that transfinites of vehicle.By two-dimentional plate type sensor (10), shear force sensor (11), weight sensor (14) obtains the axle weight of passing lorry, the analog signal of transverse force, send into data collecting instrument (17), through signal, amplify, filtering is processed and A/D obtain after changing lorry through after Wave data with interrupt mode, send into industrial computer (18), computing machine by the data analysis obtaining with resolve, obtain the gross weight of various vehicles, vehicle dry weight, quiet wheel load, clean axle weight, accumulative total is passed through gross weight, average axle weight, overload and unbalance loading trailing or leading bogie weight, trailing or leading bogie left and right weight difference, wheel flat, the results such as derailment coefficients, the vision signal that system obtains colourful CCD video camera (15) by optical transmitter and receiver (20) is imported video recording industrial computer (27) and screen test into through video distributor (28), import three-dimensional laser scanner (1) into bottom transfinite signal that industrial computer (26) and light curtain (7) obtain and import the end industrial computer (25) that transfinites into, the data that workstation (18) and industrial computer (19) are obtained are imported server (24) into, and industrial computer (26) transfinites in bottom, the end industrial computer (25) that transfinites imports the data after analyzing and processing into server (24), and last server is processed the data of obtaining are unified, show, print, upload.
