Full-automatic road one of the pen machine major function that tracks is exactly that scientific and reasonable old line sprays again.Traffic mark passes through Situations such as exposing to the weather, general wear, will appear smudgy problem, needs to carry out old line at this time and sprays again.It needs to carry out old line The problems such as section of spraying, some will appear road surface portion concave, subgrade settlement, kerb is damaged.The present invention walks straight at this time Mode is based on the observation of the first camera 60.It is sprayed to more accurately control the starting spraying of spraying lineation device with stopping It applies, positioning device further includes second camera 70, is installed on 20 bottom of car body, and in 60 rear side of the first camera, be configured to Initial position and the stop position of old traffic mark are detected, so that the starting of control control spraying lineation device sprays and stops Spraying.Second camera 70 is preferably TSL1401 line array CCD camera, OV7620 digital camera head etc..In the front of vehicle bottom TSL1401 camera is installed, the position and end position start to old line is detected in real time, and is installed in Vehicular body front The first camera 60 determine walk histogram formula, compared to the form of construction work that traditional old line sprays again, construction efficiency of the present invention is more Height, the new line of spraying and the registration of old line are higher, and construction quality is substantially improved.
The present invention, which has, independently to track, carries out the ability that traffic mark spray is drawn, and reduces constructor's to the greatest extent The amount of labour alleviates the daily operating pressure of construction personnel, improves construction efficiency;Histogram formula is walked using laser ranging, is kept away Exempt from many and diverse traditional artificial form of construction work (first to carry out traffic mark range measurement, then draw and determine traffic mark, finally push Pen machine carries out spray and draws a traffic mark), improve construction precision as far as possible, abbreviation work progress improves construction effect Rate reduces the use of the amount of labour.Old line sprays the registration that ensure that new line Yu old line again.That is, it is of the invention it is complete from Dynamic road tracks pen machine with higher construction precision, faster speed of application, lower labor intensity.
In some embodiments of the invention, the height of first camera 60 is 38 to 42cm, preferably 40cm;It bows Angle is spent for 28 to 32, and preferably 30 degree;Camera visual angle is spent for 80 to 100, and preferably 90 °;So that first camera Apart from being 60 to 80cm, lateral observed length is 150 to 170cm for examination before longitudinal, and it is preferably 70cm that distance is tried before longitudinal, is laterally seen Surveying length is preferably 160cm.The lateral resolution of first camera 60 can be 320, can be calculated the error essence of each pixel Degree is 0.5cm, therefore car body has the coincidence error of 0.5cm or so relative to old markings, and construction requirement is missed no more than 1cm Difference, therefore this programme meets construction requirement.
In some embodiments of the invention, the present invention detects graticule by second camera 70 and begins to stop, and process control makes The every 20ms of the second camera acquires an image and image procossing, then control device according to the processing result of image data come The start and stop of control spraying lineation device, for example, spraying lineation device just carries out air brushing work when detecting original white line Industry, when can't detect original white line, spraying lineation device just stops working.Because spraying lineation device is opened, is closed Close delay be about 0.5s, that is to say, that since module detect original white line to spraying lineation device really air brushing work when It waits, the time delay of 0.5s+20ms=520ms or so is had during this, calculated by speed 5.04km/h, when this section of air brushing postpones The interior air brushing error in length missed is 5.04km/h*520ms=0.7cm or so, and construction requirement is no more than 1cm error, because This this programme meets construction requirement.
In some preferred embodiments of the invention, full-automatic road track pen machine further include coating quality detection dress It sets and warning device.Coating quality detection device is third camera 80, car body 20 is installed on, to shoot on road surface and road surface The partial sector of traffic mark that draws of spraying lineation device 40, and then make control device 30 according to road surface and part area The quality for the traffic mark that section judgement spraying lineation device 40 is drawn.Warning device may include amber light and alarm.Further Ground, third camera 80 can be TSL1401 line array CCD camera, i.e. OV7620 digital camera.
In some embodiments of the invention, the full-automatic road pen machine that tracks further includes multiple ultrasonic distance measurements sensing Device is set to car body 20, and is distributed along the circumferential direction of car body 20;Multiple ultrasonic distance-measuring sensors and 30 phase of control device Even, to detect whether that object enters within the scope of the safe distance of car body 20, so that in the peace for thering is object to enter car body 20 When within the scope of full distance, so that control device 30 is controlled car body 20 and stop movement.
In traditional road traffic mark form of construction work, manual operation pen machine is needed to construct.However it is traditional Road line machine do not have traffic sign line mass (interruption, change width etc. whether occur) detection function, need human eye into Row observation, identification is low, and subjectivity is strong, and can not carry out parametrization detection to the quality of traffic mark.Construction personnel into When row construction, need constantly to pay attention to the environment of surrounding.When being in an emergency or constructor is when overworked and absent-minded, easily It causes danger.Spray head rear is mountable in the present invention TSL1401 camera, traffic mark whether can occurs to traffic mark The problems such as will line interruption, change width, is measured in real time.Traffic mark and road surface color contrast between spraying is obvious, can To detect spraying effect with third camera 80.When there is the problems such as incomplete interruption in the traffic mark of discovery spraying, this hair Bright emergency braking at once, amber light is lighted on control panel, and is sounded an alarm.The present invention is equipped with ultrasonic wave around vehicle body simultaneously Range finder module can carry out real-time monitoring to ambient enviroment.In construction, before being strayed into boundary of works area or the present invention if there is pedestrian When there is barrier in side, the present invention can carry out emergency braking and sound an alarm, and remind staff to come to handle, remind construction with this Emergency occurs for personnel.When traffic mark is drawn in present invention spray, it is possible that painting quilt in spray head or the blocking of paint road, paint case The case where being finished, if there is above situation, the present invention also capable of emitting alarm.Therefore completely new road walks direct-injection and applies lineation device 40 It is more intelligent, it constructs safer.Compared to present artificial judgment, the present invention judges more accurate, free of discontinuities, efficiency It is high.During construction, reduce the participation of constructor, be greatly saved it is artificial, and with traditional new form of construction work of mark Entirely different, construction efficiency greatly increases.
In order to make 20 smooth ride of car body, the especially smooth-ride in turn section, full-automatic road tracks pen machine, It is characterized in that, car body 20 includes speed detector and segmentation differential turning system.Speed detector is configured to detection car body 20 travel speed, so that control device 30 controls car body using incremental timestamp algorithm according to the travel speed detected 20 travel speed.
Pen machine on the market or without the ability advanced automatically now, that is, need construction personnel to push advance, Spraying lineation device 40 is only simply drive to advance.The present invention at work, can be automatically according to the angle of Nose Wheel Steering Degree to carry out differential driving to rear-wheel, keeps the quality for spraying traffic mark of the lineation device 40 in detour scribing line higher, and And keep the car body 20 when excessively curved of car body 20 more stable, prevent the generation for toppling over accident.
In some embodiments of the invention, the first camera 60 is being carried out in use, by the first camera 60 Timing diagram it is found that the data that can be realized by the triggering interrupt processing to low and high level real-time acquisition, realize highway on The determination of existing traffic sign line position.In process control, letter is interrupted by the row that 16,19 pins to GPIOA carry out image Number HERF, field interrupt signal VSYN acquisition, 8 pins for passing through GPIOD carry out the pixel interrupt signal PLCK acquisition of image.Every touching Acquisition signal of sending out row primary, the channel of DMA is enabled primary, and the first camera 60 reads a line image data, row acquisition counter mark Will ROW_Count is primary from adding, and as ROW_Count=240, illustrates that piece image acquisition finishes, row acquisition flag bit Is_ SendPhoto closes the enabled closing in channel of DMA, guarantees the complete transmission of image.When interrupt signal triggers on the spot, row acquisition mark Will position is opened, row is counted and reset, and starts to resurvey lower piece image, such circle collection.First camera 60 is acquired Image information, we can not directly use, it is also necessary to binary conversion treatment be carried out to it by the method for software, after facilitating Continuous control calculates.The binary number that one Pixel Information is 8, so according to the light intensity of the pixel, the first camera 60 It can be translated into the digital quantity of 0-255, light intensity is bigger, and the numerical value is higher, because of the black of the white line in road and its background Pitch contrast is obvious, so the two can be distinguished using suitable threshold value.By to equipped with data information Two-dimensional array is handled, we can calculate the right boundary of white line, and then finds out the position center of acquired white line, Then it is made the difference with the theoretical intermediate value MIDDLE of vehicle body, finds out the deviation centerERR of each row data in image.According to different power Again to deviation carry out it is cumulative sum and handle to obtain sum, the size description of sum car body 20 deviates the angle of white line, then leads to Suitable differential, course changing control are crossed, being overlapped and carry out old line and spraying work again for vehicle body and old line may be implemented.It is sprayed again in old line In the process, counting one of difficult point is exactly to determine that the beginning off-position of spraying is set.In some optional embodiments, using color sensor come It identifies traffic mark start and stop, but because it is not comprehensive using complicated and detection, abandons this kind of scheme, then using the The identification that two cameras 70, i.e. tsl1401 linear array ccd carry out white line is worked well with controlling the switch of spray head.Linear array ccd energy The image data for enough scanning a line generates final image in conjunction with process control according to light reflected intensity.It is adopted in white line detection With two linear array ccd, i.e. second camera 70 and third camera 80.Ccd before spray head carries out the work of traffic sign ray examination, The switch of spray head is controlled by it;The ccd at spray head rear carries out coating quality and detects work, when the spray head detects the spraying of white line When quality is problematic, it can immediately stop spraying, stop and alarm, construction personnel is reminded to check reason.
In order to enable car body 20 smoothly along road running, need to measure the speed of car body 20 in real time, therefore, we Case obtains the travel speed of car body 20 by speed measuring module (i.e. speed detector), it is compared with given speed, structure At closed loop feedback system, the control to 20 speed of car body is realized.It is controlled by the duty ratio of pwm signal in control motor driven The average voltage at direct current generator both ends, and then regulation speed.If without speed measuring module, under opened loop control state, motor speed It will receive several factors influence, such as the frictional force of motor drive, road friction power, cell voltage, front wheel steering angle.These because Element can all cause 20 fluctuation of service of car body.After speed measuring module, the closed loop feedback control to speed may be implemented, so that it may It eliminates above-mentioned factor and adverse effect is run to intelligent vehicle, keep car body 20 more stable when running.Digital IIR filters are calculated Method includes position model and increment type PID, in order to avoid in historical data error it is cumulative, the design uses increment type PID.Increment Type algorithm has lot of advantages:What incremental algorithm calculated every time is to export the increment of control amount, and control amount is to need to add The output quantity of last time, the probability for generating malfunction in this way substantially reduce;Incremental algorithm does not need to do cumulative, and the determination of increment is only And deviation sampled value is related several times recently, and computational accuracy is smaller on the calculating of control amount influence, and position type algorithm will be used The accumulated value for going deviation is easy to produce big add up error;Using incremental algorithm, it is easy to accomplish manually to automatically without impact Switching.Control programming is according to (by taking revolver as an example):
SpeedL=(s16) (last_moto_speedL+sp* (speedE1L-speedE2L)+si*speedE1L)
Wherein:SpeedL is that n-th exports control amount;Last_moto_speedL is (n-1)th output control amount; SpeedE1L is n-th deviation;SpeedE2L is (n-1)th deviation;Sp is proportional gain factor;Si is integration gain factor.
Further, there are many kinds of the methods to test the speed, i.e., speed detector can there are many, such as with speed-testing engine, Reflecting light electro-detection, transmission type photoelectric detection etc..This using transmission type photoelectric encoder, inside be photoelectric tube Grating encoder is added to constitute, structure is simple, and stability is high.The rotary shaft of decoder internal is connected with the rotation axis of motor, by revolving Shaft drives rotating disk to be rotated, and the light that light source issues is received through the slot in rotating disk by light receiving element, thus Export pulse number.Pulse number by calculating photoelectric encoder output per second can calculate the revolving speed of motor.
