The inventions relate to the field of construction and operation of road networks, as well as to the means and methods of comprehensive diagnostics of operational indicators of road facilities and the organization of monitoring of their technical and operational status in real time.

The prior art method for monitoring a road network through a mobile road laboratory. According to this method, the technical and operational parameters of the road object are monitored by moving along the roadway a control and measuring system with a coordinate coordinate measuring means and with a functional complex based on at least one optoelectronic component. To do this, the aforementioned system is permanently installed on the base vehicle using a vibration-insulated base for mounting at least part of the functional means of the control and measuring system and switching output channels of its subsystems with an on-board computer complex, functionally a means of processing the recorded information and transmitting the results to a central computer in digital form in real time (RU, No. 2170298, C2, 2001).

The prior art functional complex of a mobile road laboratory for monitoring the road network. This complex includes an optoelectronic component intended for stationary installation on a base vehicle by means of a vibration-insulated base, at least one (which is an integral part of the control and measuring system of a mobile road laboratory). The output channels of this at least one optoelectronic component are functionally switched communication structures with an on-board computer complex, which is a means of processing the recorded information and transmitting the results to a central computer in digital form in real time (RU, No. 2170298, C2, 2001 )

The disadvantages of the data of technical solutions known from the prior art (both in relation to the object “method” and in relation to the object “device”) include limited operational capabilities, due to:

- limited measurement accuracy of the investigated parameter of the road object, due to the discreteness of the location of the functional elements of the optoelectronic component relative to the surface of the roadway and, as a result, measurement and recording of information from its individual (discrete) points;

- ensuring control and registration of only one technical and operational parameter of a road object;

- lack of control and registration of the state of the elements of the arrangement of the road facility, including overhead communications;

- a limited control zone, regulated by the gauge of the base vehicle.

The claimed technical solutions were based on the task of expanding the functionality of a mobile road laboratory for the implementation of the claimed method, by providing integrated monitoring and recording of a number of basic technical and operational parameters of pavement, as well as monitoring and recording the state of the arrangement of a road object (including overhead communications ) in real time, while increasing the accuracy and reliability of the measurement results, by linking the cut measurement measurements to the relative and absolute coordinate systems while increasing the productivity of the process of integrated monitoring of the street transport network as a whole by expanding the range of functional technological monitoring and registration tools that work simultaneously in the monitoring process.

- use (in each of the indicated subsystems) of three-dimensional volumetric scanning cameras as recording means, and laser rails as forming light-ranging devices (forming continuous volumetric scanning lines of a given length within the viewing angle of the lenses of three-dimensional scanning cameras);

- providing the possibility of forming a subsystem for measuring the longitudinal evenness of a road object based on a three-dimensional scanning camera and a laser rail (forming a solid line of volumetric scanning of a given length within the viewing angle of the lens of a three-dimensional scanning camera), i.e. exceptions to the structure of this subsystem of such functional means as acceleration sensors (accelerometers) of the optical platform.

In addition, another technical result (provided by the claimed technical solution) is the provision of the ability to operate with a given accuracy and resolution of such subsystems as subsystems for registering defects of the roadway and elements of the arrangement of the roadway (functionally a means of two-dimensional assessment of the mentioned defects of the road surface) and subsystem registering the state of arrangement of a road object (which is functionally a means of assessing the state of elements of the road tricity to the right, left, and above the trajectory of the base vehicle) in the conditions of illumination of the elements of the road object that do not meet the specified illumination parameters (regulated by the properties of the optoelectronic channels of the linear scanning cameras of the corresponding subsystem), due to the use of local illumination of the studied areas of the surfaces of the road elements in these subsystems object without deterioration of the conditions of daily regular operation of the road object by other transport redstvami (i.e. it excludes the possibility of creating emergencies at a road facility during monitoring).

The claimed method for monitoring the road network through a mobile road laboratory is implemented as follows.

The control of the technical and operational parameters of the road object is carried out by moving along the roadway 8 of the control and measuring system with the coordinate coordinate measuring means of the controlled parameters and with a functional complex based on at least one optoelectronic component. To do this, the aforementioned system is permanently installed on the base vehicle 1 (including the operator’s workstation 3) using a vibration-insulated base for mounting at least part of the functional means of the control and measuring system and switching output channels of its subsystems with the on-board computer complex 2 are switched. it is functionally a means of processing recorded information and transmitting results to a central computer in digital form in real time. As a vibration-insulated base, a frame 5 with an optical base 6 is installed permanently mounted above the vehicle. As part of the functional complex, one of the optoelectronic components is the subsystem for measuring the longitudinal evenness of the pavement coating surface, by means of which the microprofile of the mentioned surface is constructed in the longitudinal direction. Why this subsystem is structurally organized on the basis of at least one three-dimensional volumetric scanning camera 7 and at least one laser generator 9 of the volumetric scanning line, which is formed at least along one traffic lane. The volumetric scanning chamber 7 and the laser generator 9 of the volumetric scanning line are spatially arranged on the optical frame 6 with the possibility of scanning all three points along the base length of the generated laser line in each scanning frame by means of the three-dimensional camera 7. The speed of the vehicle 1 is correlated with the frame rate of the scan with the possibility of providing partial overlap of images formed in adjacent frames. In the process of scanning the generated laser line by means of a three-dimensional volumetric scanning chamber 7, direct construction of a profilogram of a longitudinal section of the surface of the road surface is performed by processing the scan results directly in the three-dimensional chamber 7.

It is optimal to measure the parameters of the longitudinal evenness of the surface of the road surface using a volumetric scanning chamber 7 with a resolution providing registration and construction of a microprofile of the surface of the road surface in the longitudinal direction with a pitch of at least 125 mm and an accuracy of 0.1 mm.

Currently, the longitudinal evenness of the roadway 8 is measured mainly by combining a laser rangefinder and an acceleration sensor.

The present invention proposes a fundamentally different optical scheme for measuring longitudinal evenness.

Longitudinal evenness is measured by directly constructing a longitudinal profile by means of at least one digital camera 7 for volumetric (three-dimensional) scanning and at least one laser generator 9 (in the form of a laser rail) of a light line that is formed along the roadway 8, those. along the direction of movement of the base vehicle 1.

When using the base vehicle 1 with a base of 4.1 m, the length of the laser rail (generator 9) can be up to 6 m, and when using the mentioned vehicle 1 with a base commensurate with the base of the bus, the length of the laser rail (generator 9) can be increased up to 20 m.

The physical principle of the method is that, through a three-dimensional volumetric scanning chamber 7 of the formed laser line, during the scanning process, not transverse, but longitudinal unevennesses of the roadbed 8 are measured and recorded.

The light (laser) line (depending on the layout of the optical system as a whole) can be formed as in the own track of the base vehicle 1 (the safest option from the point of view of road safety for participants in this movement, since the glare effect is completely eliminated, i.e. effects on the lens and retina of the eye, road users through laser radiation, for example, an invisible infrared laser beam), and in at least one adjacent rut. In the latter case, certain precautions are needed to prevent the aforementioned blinding effect. For example, the laser line should be formed on the side of the base vehicle 1 at a distance not exceeding the minimum permissible distance between the parallel streams of vehicles (for example, within the layout marking the width limits of the respective transport lanes of the roadbed 8, if any, or by using light to form laser radiation lines with a wavelength safe for the human eye).

A combined variant of the formation of a longitudinal laser line, i.e. both in the track of the base vehicle and in the ruts adjacent to it (lanes of the roadway).

As a digital camera 7 volumetric scanning can be used, for example, a camera company "SICK". A feature of volumetric (three-dimensional) scanning cameras is that simultaneously with scanning the studied area of the scanning object, profiles are processed directly onto the matrix, for which purpose special processing means are introduced into its structure, for example, in the form of transistors. As a result, during processing, the coordinate of the brightest pixel falls out of the camera. At the exit, we have a finished profile line of the scanned section of the surface of the roadway 8.

The advantage of this option for measuring and registering longitudinal evenness is the possibility of excluding acceleration sensors from the optical registration and measuring system, which simplifies the processing of information obtained as a result of scanning and significantly increases the processing speed and accuracy (reliability) of information about the state of longitudinal evenness of the roadway 8.

When using one volume 7 scanning camera 7 in the considered optical system, simultaneous scanning of at least 1500 points of the generated laser line is ensured. A quantitative increase in the said chambers 7 in the considered optical registration system for the longitudinal evenness of the roadway 8 proportionally increases the number of simultaneously scanned points of the corresponding surface section of the roadway 8, which significantly increases the accuracy of measurements and the reliability of the final results of assessing the state of the roadway 8.

In addition, the real longitudinal irregularities of the roadway 8 with a wavelength of irregularities exceeding the measurement base of the used optical system can be calculated mathematically. This is explained by the fact that scanning is carried out with a certain frame rate in such a way that there are no spaces between successive frames in time, i.e. mutual overlapping / overlapping / adjacent frames is provided. For example, at a scanning frequency of 10 frames per second and a base vehicle moving speed of 30 km / h, the shift between consecutive frames (along the light / laser / line) will be 1 m, which is significantly less than the length of the scanning section regulated by the viewing angle (scan) of the lens three-dimensional camera 7. Therefore, the overlap size of adjacent scanning frames of the investigated surface can be regulated depending on the speed of movement, scanning frequency and the viewing angle of the lens Just the camera 7 surround scan.

The laser generator 9 of the volume scan line can be used (in order to increase the safety of the proposed method) in a pulsed mode, i.e. generate laser pulses with a frequency synchronized with the frame rate of the scan camera 7.

It is advisable to form a control and measuring system multidisciplinary, for which, as part of its functional complex, additional optoelectronic components are used, which are functionally:

- a subsystem for registering defects in the carriageway of a road object and elements of its arrangement, by means of which a two-dimensional assessment of the above-mentioned defects and elements of arrangement is carried out, for which this subsystem is constructively organized on the basis of a linear camera 10 of scanning;

- a subsystem for registering the state of arrangement of a road object, by which an assessment is made of the state of elements of arrangement on the right, left and above the path of the base vehicle, for which this subsystem is constructively organized on the basis of at least two linear cameras 12 and 13 of the side and top scanning .

These subsystems are spatially organized on an optical bed 6 with the possibility of visualizing in their field of view the aforementioned controlled elements of a road object. At least one of the mentioned subsystems of the functional complex of the control and measuring system is equipped with a means 20 for local illumination of the studied areas of the surfaces of the elements of the road object in conditions of their illumination that do not correspond to the specified illumination parameters, regulated by the properties of the optoelectronic channels of the linear cameras 10, 12 and 13 of the scanning of the corresponding subsystem. This local illumination device 20 is structurally and spatially arranged on an optical frame 6 with the possibility of forming in the field of view of the lenses of the said linear cameras 10, 12 and 13 scanning light flux with cross-section geometry in the form of a light strip with a given distribution of illumination along the length and width of this strip. At the same time, the width of the said lane is calculated from the condition of ensuring the exclusion of blinding of traffic participants at the moment of crossing the formed light strip in the process of regular road traffic with a legally permitted speed.

The linear camera 10 of the scanning subsystem of the registration of defects of the carriageway of a road object and its arrangement elements is placed mainly in the region of the front cantilever part of the optical frame 6. In this case, a camera 10 with technical characteristics is used, which makes it possible to register the aforementioned defects on the width of the road surface up to 12 m with an accuracy of transverse and longitudinal directions of 10 mm.

Linear cameras 12 and 13 of the side and top scanning subsystems for registering the state of arrangement of a road object, which is functionally a means of assessing the condition of objects of arrangement on the right, left and above the path of the base vehicle 1, are placed in the central part of the optical frame 6 on opposite sides of its longitudinal axis . And the structural elements of this tool are constructively and spatially organized with the possibility of registering the status of the respective controlled objects to the right, left and above the path of the base tool 1 at a distance of 6 m with an accuracy of 10 mm.

Equipping the above subsystems with means 20 for local illumination of the scanned section of the roadway allows you to obtain information about the state of the surface of the investigated elements of the road object both in low light conditions and in conditions of excessive (solar) illumination. In the latter case, the tool 20 is functionally a means of reducing contrast under conditions of excessive (solar) illumination at a certain location of the sun relative to the surface under study of the corresponding element of the road object.

Used to implement the above method for monitoring a road network, the local illumination means 20 includes: a light source 24; a hollow body 25 with a window for the exit of the light flux 21 generated by the light source 24 located in the cavity of the body 25; at least one means of transforming the geometry of the light flux generated by the source 24.

Said light source 24 is made of an electronic type, and it must contain at least one high-pressure discharge lamp 27 equipped with a burner 28 mounted on current leads 29 welded into the leg 31 of the outer bulb 30. At least half of the inner surface area the flask 30 is covered with a reflective mirror layer 33 so that the plane passing through the extreme sections of this layer 33 is oriented along the longitudinal axis 34 of the burner 28. The shape of the formed reflective part of the layer 33 of the outer bulb 30 is selected so second that for any cross-sectional ratio r ₀ of the distance from the axis 34 of the burner 28 to the reflective layer 33 in the longitudinal plane of symmetry of the corresponding distance r _φ plane (rotated around the axis 34 of the burner 28 by an angle φ) varies continuously with the change in the angle φ lies mainly in the range of 0.7-1.1.

At least one means of transforming the geometry of the light flux 21 generated by the source is made in the form of a slotted collimator 35 of the generated light flux 21, which (i.e. the collimator 35) is placed across the last (light flux 21) so that the light flux 21 generated by the source 24 can overlap and is made in the form of a set of 36 parallel plates 37 mounted with gaps between their mutually inverted surfaces 38 (reflecting or absorbing, i.e., blackened).

In this case, the housing 25 of the local illumination means 20 is equipped with instrument dampers 39 (mainly rubber), which are functionally suspension elements of the local illumination means 20 on the frame for mounting the functional means of the optical component of the registration and measuring system (or on the optical frame) with the possibility of providing illumination of the studied surface areas elements of the road object.

The geometry of the slit collimator 35 is calculated from the condition of ensuring the formation of a light strip 23 of such a width that eliminates the manifestation of the glare effect of traffic participants at the moment of crossing the formed light strip 23 in the process of regular road traffic with a legally permitted speed.

Suspension of the housing 25 means 20 on the instrument dampers 39 allows you to cut off high-frequency vibrations (generated by vehicle 1). And this increases the service life of the high-pressure lamps 27 used in the lamp, which are located horizontally relative to the roadway, and the own weight of the bulb 30 of the lamp 27, when perceiving high-frequency vibrations, can provoke its destruction (kink) in the connection zone between the bulb 30 and the cap 32 of the lamp 27.

The plates 37 in the set 36 of the slit collimator 35 can be made with either mirrored (reflective) surfaces 38 or blackened (absorbing) surfaces 38. In the first case, the energy parameters of the light flux generated by the collimator 35 are increased 21, however, from the point of view of technology the manufacture of plates 37 the manufacturing process of polished surfaces 38 is more time consuming. The manufacturing technology of the blackened surfaces 38 of the plates 37 does not present any difficulties from a technological point of view, however, in this case, the effect of reducing the energy parameters of the light flux 21 formed by the collimator 35 (which is compensated by using the high-pressure lamp means 20 in the above construction , i.e. with a mirror reflective layer 33 on the inner surface of the bulb 30 of the lamp 27). In addition, the use in the means 20 of the local illumination of lamps 27 of this design allows you to exclude from the design of the means 20 additional reflectors (reflectors) with high overall dimensions.

It can also be noted that the use in the design of the means 20 for local illumination of plate-shaped collimators 35 increases the safety of the monitoring process in the conditions of regular road traffic on the highway, since in the case of an emergency chip 30 bulb 27 from the cap 32, the bulb breaks on the plates of the collimator 35 and gets on the roadway in the form of a small placer without causing an emergency.

The use of electronic voltage frequency converters in the design of the light source 24 makes it possible to abandon electric transformers having high overall dimensions and necessary for the operation of the lamps 27 of the construction in question from a voltage source of 220 V.

The width of the light strip 23 (formed by the collimator 35) along the roadway 8, as a rule, is 0.5-0.6 m, which allows passing along the oncoming and oncoming traffic flows this zone of possible blinding for hundredths of a second, which eliminates the creation of an emergency on the road.

Means 20 local backlight operates as follows.

A ray of light leaving the center of the burner 28 in the direction of the mirror reflecting part (mirror layer 33) of the outer bulb 30 falls on the mirror layer 33. Since the ratio r ₀ / r _φ constantly changes with φ, the normal to the mirror surface of the layer 33 in the point of incidence of the beam will not be directed to the longitudinal axis 34 of the burner, but past it. Due to this, the beam reflected from the mirror surface of the layer 33 passes outside the zone of the burner 28 and is not attenuated therein (i.e., it leaves the bulb 30 of the lamp 27 with a minimum loss of the light energy generated by the source 24). The rays of light leaving the burner 28 in the direction of the exit window 26 exit the bulb 30 of the lamp 27 without reflection, i.e. also practically without loss generated by the light source 24. Thus, the luminous efficiency of such a lamp 27 is higher than the luminous efficiency of a lamp with a round-symmetrical bulb. In addition, by forming lamps 27 with different profile geometry of the mirror layer 33 (i.e., with different ratios of the dependence r ₀ / r _φ = f _(φ) ), it is possible to obtain light sources 24 with different light distribution over the cross section of the generated light flux 21.

If the ratio r ₀ / r _φ = f _(φ) takes values either more or less than unity, and as the absolute value of the angle φ increases and decreases, the geometry of the profile of the reflecting surface of the mirror layer 33 has, as a rule, convex-concave shape (see Fig.6). If the mentioned ratio constantly decreases with increasing modulus of the angle φ, then the profile geometry of the reflecting surface of the mirror layer 33 has an exclusively convex shape (see Fig. 7). Angle modulus increase

| φ _max |> 90 ° expands technological capabilities when creating lamps 27 with different light distribution. However, at | φ _max |> 115 °, the fraction of radiation coming out after repeated reflections substantially increases, as a result of which the energy return of the light source 24 (electron gas discharge lamp 27) decreases.

In particular, the lamp 27 used in the present invention with a burner from a 100 W DNaT lamp, a profile of the reflecting surface of the mirror layer 33 of the outer bulb 30 corresponding to FIG. 7 (r ₀ / r _φmax = 0.82), and a coverage angle | φ _max | = 105 ° has a luminous efficiency (luminous efficiency) of 75.3 lm / W, while a similar lamp with a round-symmetrical bulb and | φ _max | = 105 ° has a luminous efficiency (luminous efficiency) of 69.8 lm / W.

It is advisable in the process of monitoring the road network to carry out three-dimensional construction of the microprofile of the surface of the road surface in the transverse direction, for which purpose the structure of the functional complex as an additional optoelectronic component also includes a subsystem for measuring the transverse evenness of the surface of the road surface, which is installed on the optical frame 6 and is structurally organized based on at least one laser generator 14 or 15 of the volumetric scan line and camera 16 volumetric th scanning.

It is optimal that the subsystem for measuring the transverse evenness of the pavement coating surface is structurally organized on the basis of two laser generators 14 and 15 of the volume scan line, which are installed, for example, in the front of the console of the optical frame 6 with the possibility of forming a volume scan line in front of the base vehicle 1, and the volumetric scan chamber 16 of this means is placed on said bed 6 with the possibility of arranging the volumetric scan line in the region of the field angle z eniya its lens. At the same time, the structural elements of this subsystem are structurally and spatially organized with the possibility of registration and construction of the microprofile of the pavement in the transverse direction up to a width of 12 m with an accuracy of 2 mm.

It is reasonable in the process of monitoring the road network to coordinate the measurement results of the controlled parameters obtained during operation of all the above subsystems to carry out the relative and absolute coordinate systems. For this, the control and measuring system includes subsystems of relative and absolute positioning, the first of which is functionally a means of linearly linking the measurement results to a relative coordinate system, which is constructively organized on the basis of an encoder, and the second is a means of linking the measurement results to an absolute coordinate system, which constructively organized on the basis of satellite navigation system 19.

It is optimal to:

- the structural elements of the means of linearly linking the measurement results obtained during operation of all of the above subsystems to a relative coordinate system, including an encoder (not shown conventionally in graphic materials), would be structurally and spatially organized with the possibility of providing linear linking of the measurement results to the relative system coordinates with an accuracy of at least 0.15%, that is, 1.5 m per 1 km of the route;

- the structural elements of the means of linking the control results obtained during operation of all the above subsystems to the absolute coordinate system, including the satellite navigation system 19 (for example, GPS), would be structurally and spatially organized with the possibility of linking the measurement results to the absolute coordinate system with legal accuracy.

It is advisable that at least part of the structural elements of the optoelectronic components of the functional complex of the control and measuring system is vibration-insulated relative to the optical frame 6 by means of individual vibration mounts.

It is permissible to additionally include at least a two-level GPR sensing subsystem in the control and measuring system.

One of the levels of this subsystem is functionally a means of assessing the dielectric constant of structural layers of pavement and underlying soils to record the thickness of structural layers. The design of this level is equipped with at least one GPR 17 short-wave range sensing.

Another level of this subsystem is functionally a means of registering engineering networks crossing the roadway of a road object, as well as various heterogeneities in the ground. The construction of this level is equipped with at least one GPR 18 of the long-wave range of sounding.

Optimal:

- the structure of the means of assessing the dielectric constant of the structural layers of pavement and underlying soils include two georadars 17 with a linear sensing range of 0.05-1.0 m, which are placed in front of the frame 5 of the base vehicle 1 across its longitudinal axis, while the structural elements of this tool are structurally and spatially organized with the possibility of registering the thickness of the structural layers with an accuracy of 1 cm at a depth of 0.5 m and with an accuracy of 3 cm at a depth of 0.5 m to 1 m;

- the composition of the registration means of engineering networks crossing the roadway of a road object, as well as various heterogeneities, also include two GPR18 with a linear sensing range of 0.5-10.0 m, which are placed in the rear of the frame 5 of the base vehicle 1 across its longitudinal axis while the structural elements of this tool are structurally and spatially organized with the possibility of registration of utility networks crossing the roadway with a depth of up to 10 m from the surface of the road surface And various irregularities up to 0.5 m.

From a physical point of view, the operation of the registration and measuring system of the ADS-MADI complex, in particular its optical component, is organized on the basis of the above optical structures and subsystems (well known from the “prior art”, that is, laser generators, linear and volumetric scanning cameras basis of photosensitive rulers), based on the principles and laws of geometric optics, as well as optoelectronics and, therefore, does not require additional explanations.

The advantages of the scanning method used in the claimed technical solution by means of digital optical cameras based on photosensitive lines (relative to television cameras used for similar purposes) are as follows:

- the absence in the on-board computer memory of unnecessary information about the surface of the scan object being examined, because each point of the scanned surface is registered in the storage device only once;

- automatic combination of the beginning of the next frame with the end of the previous one during the shooting process without any overlapping frames one on top of the other;

- the ability to use a system of automated pattern recognition in the process of processing and researching the captured visual information about the studied object in connection with minimizing the amount of visual information about the object necessary for its qualitative assessment according to the standard point system and corresponding quality parameters;

- a significant increase in the speed of processing and data transmission over a distance in connection with a multiple decrease in the amount of information flow necessary to obtain the final information about the object (in particular, its visualization with a given resolution);

- objectivity in assessing the quality parameters of scanned objects of research in view of the possibility of multiple visual assessments of information obtained about the object by independent experts and the prompt resolution of disputes by re-joint analysis of information with the participation of third parties (specialists);

- Regular 100% (and not selective) monitoring of motorways and other objects of road facilities for the purpose of their qualitative assessment and identification of priority areas requiring repair, which dramatically increases road safety, especially on busy urban highways of megacities;

- the ability to determine the wear rate (aging) of the investigated objects by overlaying the full subsequent picture of the object to the previous one in automatic mode (that is, the ability to assess the dynamics of the destruction of the studied objects in time in order to form a predicted schedule for ensuring planned repair and construction works);

- the sampling time of the sampling frames is carried out by the encoder (located on the fifth wheel of the base vehicle or in the gearbox) with reference to the mileage of the road (i.e., the distance traveled by the vehicle carrying the scanning device) and not to time, which eliminates duplication of one the same information;

- synchronous comprehensive (in several respects) assessment of road surfaces and other elements of road construction in relation to the mileage of the road through a satellite navigation system (for example, GPS system), i.e. reference to the absolute coordinate system.

Comprehensive registration of technical and operational indicators of the studied objects, in particular, includes:

- two-dimensional scanning;

- three-dimensional scanning;

- sounding by georadars;

- measurements of the upper dimensions of systems and elements of the arrangement of roads;

- measurements of distances and dimensions of the arrangement elements on the sides,

- linking the scan results to the mileage of the road.

In the broad sense, linking means linking the scan results to the corners of houses, kilometer posts, road signs, essential elements of the arrangement of roads, such as overpasses (beginning of the bridge - end of the bridge), to the lighting.

If the exact length of the brand of the machine is known, then from the image obtained by means of the side scanner, it is possible to determine (by recounting) its speed due to the effect of “shortening its length” during the scanning time period (the longer the image of the machine, the lower its relative speed).

This effect smoothes the effect of closing the roadway 8 with an oncoming traffic stream, and at a low speed of the autolaboratory (about 30 km / h), the associated flow.

If you select the ADS-MADI base accordingly and place two scanning subsystems identical in functionality at the beginning of the ADS-MADI base vehicle and at its end, then getting the same car simultaneously on two scanners is practically impossible.

These two effects make it possible to see the road almost “empty” when scanning, that is, as if there were no oncoming and passing vehicle flows during the scanning process.

The increase in the number of axles of the base vehicle ADS-MADI reduces the frequency characteristics of vibration and thereby improves the quality of shooting.

The functional complex of the mobile road laboratory for monitoring the road network includes, for stationary installation on the base vehicle 1 by means of a vibration-insulated base, at least one optoelectronic component (which is an integral part of the control and measuring system of the mobile road laboratory). The output channels of this at least one component are functionally structures of communication with the on-board computer complex 2. The latter is a means of processing the recorded information and transmitting the results to a central computer in digital form in real time.

As at least one of the optoelectronic components, a subsystem for measuring the longitudinal evenness of the pavement coating surface is used, which is functionally a means of constructing the microprofile of the said surface in the longitudinal direction. The design of this tool is equipped with at least one three-dimensional volumetric scanning chamber 7 and at least one volumetric scanning line laser 9 made in the form of a laser bar. In this case, the volumetric scanning chamber 7 and the volumetric scanning line laser are mounted on an optical bed 6 (which is functionally a vibro-insulated base) and spatially organized with the possibility of scanning through said chamber 7 all points along a base length formed along at least one strip at the same time laser line movements in each scan frame. In this case, camera 7 is used as a volume scan camera 7 with a scan frame rate such that it can overlap the images of the scanned object generated in adjacent frames in relation to a given speed of movement of the base vehicle 1, and the structural design of the volume scan camera 7 is arranged to provide in the process of scanning the formed laser line for the direct construction of profilograms of the longitudinal section of the road surface th coating by processing scan results directly in the chamber 7.

It is optimal to use a camera 7 with a resolution 7 as a volume scanning camera 7, which ensures registration and construction of a microprofile of the road surface coating in a longitudinal direction with a pitch of at least 125 mm and an accuracy of 0.1 mm.
