Definitions
- the present invention relates to an ironing device for longitudinal road markings comprising a vehicle, at least one first set of guns to spray ironing materials on a longitudinal road marking, this set of pistols being secured to the lower part of the vehicle and directed towards the road.
- Such a device also includes control means opening and closing of the gun assembly, as well as a near vision, associated with a local control unit and comprising a local optical sensor, placed near the gun assembly and intended for locally view the marking to be ironed.
- This local optical sensor is associated with signal processing means and calculation means for determine the position of the theoretical longitudinal axis of the marking to iron.
- the device further comprises means for positioning the gun set.
- theoretical longitudinal axis of the marking the axis determined locally precisely, while the axis longitudinal “approximate” is the global axis of the marking, for example such as the sees the driver of the vehicle.
- the guns can be rotate around a vertical axis and around a horizontal axis.
- This known device has several drawbacks. Indeed, from share, and although it is partially automated, the ironing speed it allows is limited since the near vision system must locally identify the contours of each element of road markings, analyze the data and transmit, each time, the command to open and closing of the guns and the control for adjusting their position.
- this device requires a sustained attention from the driver of the vehicle, who must constantly take care to generally keep the vehicle in line with the marking at iron. This also limits the speed of ironing.
- the pistols having a defined opening angle must be placed at a specific height above the road so that the projection width of the materials of ironing corresponds to the width of the markings to be ironed.
- these pistols must be precisely positioned on the axis of the marking and their opening / closing sequence must be such that, depending on the speed of the vehicle, they are open for a time necessary to iron the lines constituting the marking to be ironed, and closed on the intervals between these traits.
- the device known from document EP-A-0129 551 is not suitable for the simultaneous ironing of two longitudinal road markings, respectively placed on the axis and on the bank of the road.
- the invention aims to remedy these drawbacks by proposing a Longitudinal road marking ironing device which allows increased ironing speed and improves ironing accuracy.
- the means for positioning the gun assembly comprise first means of vertical displacement of the first pistol assembly, first means of horizontal displacement of the first set of pistols, intended to move said set horizontally, in a direction transverse to the direction of movement of the vehicle, and of the first means for adjusting the first set of pistols.
- the device further comprises a main means servo system comprising a far vision system associated with a main control unit, said far vision system comprising a global optical sensor to visualize the width, the module and the position of the longitudinal axis of the first iron-on marking, associated with means signal processing and calculation means to determine the width, the module and the position of the approximate longitudinal axis of the first marking to be ironed, said main control unit being intended to control the first means of vertical displacement of the first set to pistols, so as to match the projection width of the ironing materials with the width of the first marking to be ironed, order the first means of horizontal movement of the first pistol assembly, so as to place said assembly above the axis longitudinal approach to the first marking to be ironed, and to order the first means for controlling the opening and closing of the first set of pistols, so as to match the sequences of projection of ironing materials with the module of the first marking at iron.
- a main means servo system comprising a far vision system associated with a main control unit, said far vision system comprising
- the first near vision system and the first unit of local control are part of a first secondary means servo control, said first local control unit being intended for controlling said first adjustment means of the first set to pistols, so as to correct the controls of the control unit main.
- the means for adjusting the first gun assembly may include horizontal adjustment means of the latter, which the local control unit commands to correct the position of this first set of pistols and make it coincide with the axis theoretical longitudinal of the marking to be ironed.
- These adjustment means can also include means vertical adjustment of the first set of guns, controlled by the unit local control to obtain a projection width equal to that of the marking and thus refining the control of the main control unit.
- They may also include means for adjusting the opening and closing of the guns.
- the invention allows tolerances of deviations from the larger vehicle path.
- the speed of ironing can be increased.
- the far vision system associated with the control unit main, used to globally configure the guns. Determining the marking module is particularly important, since it allows calculate the opening and closing sequences of the guns. So, when the vehicle is moving at constant speed over a section on which the marking module remains unchanged, opening and closing of pistols do not require any additional transmission. However, when the far vision system detects a modification of the module, the sequence opening and closing of the guns is modified.
- the main means of control determines, using the system far vision, the ironing marking module. He can then, in depending on the vehicle speed, calculate the opening and closing times gun closure, depending on which he commands directly opening and closing.
- the secondary control means can intervene by means of adjustment, to take into account possible local variations in the marking module or variations momentary vehicle speed.
- the main means of control determines that the duration of the opening of the pistols, the secondary means control then giving the command to open the guns, these being automatically closed, after the time prescribed by the unit main control.
- control unit main preposition the pistols by controlling the means of horizontal and vertical displacement, so that the secondary means has only to readjust their position if the need arises locally feel.
- Gun sets are generally made up of three pistols, the first projecting paint, mixed before being deposited on the road to microbeads of reflective glass projected by the second, and the third projecting a layer of glass microbeads used to improve the thinking and increasing the life of road markings.
- the device according to the invention can be used with a single set with guns for ironing with a single marking or with two sets of pistols, for example, in axis and in edge, for the ironing of two axis and shore markings respectively.
- the far vision system therefore views the road ahead of the vehicle, possibly over a width sufficient to encompass the axis and shore markings.
- the invention comprises one or two secondary means of control according to the number of sets with pistols.
- a secondary means servo associated with a set of pistols In case the device of the invention comprises two sets of pistols, both associated control means operate in such a way independent of each other.
- the operation of the second means secondary control being analogous to that of the first means secondary control, described above.
- a set of pistols or the two gun assemblies can be integral with one or two trolleys, themselves secured to the lower part of the vehicle.
- This or these carriages are connected to the vehicle by a vertical displacement member, allowing, during the transfer of the vehicle to raise the carts and authorize normal speed.
- These carts are fitted with wheels which are placed at the road surface contact, through the body of vertical movement of the carriage, with a view to ironing the markings.
- the device also comprises a member for horizontal displacement of carriage, in a direction transverse to the direction of travel of the vehicle. This horizontal carriage movement member can be part aforementioned means for horizontal movement of the gun assembly.
- the gun assemblies preferably being placed halfway transverse by their horizontal adjustment means, to pre-position said assemblies substantially above the approximate axis of the marking to iron.
- the horizontal adjustment and transverse pistol assemblies will be at most a setting relative, of limited amplitude.
- the means of vertical displacement of pistol assemblies, as well as their possible means of adjustment vertical move said assemblies relative to the carriages, more precisely, relative to a part of the carriages kept at a distance substantially constant from the road surface thanks to the wheels of these carts, to determine the projection width of the materials of ironing.
- the carriages are advantageously provided with a suspension by through which they are connected to the vehicle.
- This suspension allows the vertical movements of the vehicle to be decoupled from those of the carts to keep them connected to the road.
- the sensor (s) local optics are advantageously mounted on these carriages.
- the assemblies to pistols are mounted on supporting structures such as chassis, secured to the vehicle by vertical displacement members and, possibly horizontal displacement members, while the one or more near vision systems are equipped with distance sensors. These latter measure the distance between the supporting structures and the road surface. If this measured distance deviates from the target height at which one wishes maintain the supporting structures, the secondary means or means servo control the vertical displacement members for correct the discrepancy. These provisions make it possible to maintain the pistols at the desired height, even if the road has local reliefs.
- the distance sensors are for example constituted by ultrasonic systems or, more generally, by measurement systems without contact.
- the vertical displacement members of the supporting structures can then play the role of means of vertical displacement of the assemblies to pistols. In this case they are generally controlled by the unit of main control and are, if necessary, readjusted by the control unit corresponding secondary.
- the vertical displacement means and the adjustment means vertical of a set of pistols can consist of the same organ, generally controlled by the main control unit, and regulated precisely by the corresponding local control unit.
- a local optical sensor can visualize approximately 50 cm in width road.
- the near vision system includes means to process the image viewed line by line from an edge of the region viewed.
- each line processed corresponds to 1 cm of road width.
- This near vision system includes also a memory functioning like First In / First Out batteries, which stores at most 15 consecutive values each of which corresponds to a line processed. This makes it possible to determine, to the nearest centimeter, the width of the lines constituting the iron-on marking and the position of the side edges of these traits. The following calculations effectively determine the theoretical axis of the marking by eliminating the sources of error, so as to wedge the guns on this axis.
- the global optical sensor is advantageously secured to the vehicle and placed on its front part, preferably at a height sufficient for its field of vision is adapted to the simultaneous viewing of axis and shore markings.
- the various main and local control units, as well as the calculation means and the signal processing means are advantageously on board the vehicle.
- the main control unit controls the connection and disconnection of the secondary control means (s). More specifically, in case the far vision system spots a marking non-longitudinal, for example a transverse stop marking or a middle marking with zebras, the main control unit disconnects the secondary control means and controls the closing of the gun assembly (s). In case the markings not longitudinal make way for longitudinal markings, the unit of main control reconnects the secondary control means. When two markings are ironed and in the case where only one of them becomes non-longitudinal, disconnection only affects the pistol assembly concerned.
- the main control unit controls the means of command to open and close gun assemblies in operation the ironing markings module and the vehicle speed.
- the optical sensors, global and premises are constituted by cameras and the processing means of the signal are image processing means. It goes without saying that these means signal processing or image processing may consist of a single calculation system, connected to the various optical sensors.
