Definitions

  • the invention relates to a sensor system comprising a calculation unit for a road paver for calculating material consumption. Further exemplary embodiments relate to a road finisher with a sensor system. The invention further relates to a corresponding method for calculating a material consumption.
  • the automatic and continuous determination of the amount of asphalt used by the road paver is an essential aid for the operating personnel, who, among other things, have the task of checking the amount of asphalt paved in accordance with the specifications from the contract for the construction project and making corrections if there is a significant deviation from the contractual specifications is to be determined.
  • the object of the present invention is to create a concept that enables the installation amount to be determined as early as possible.
  • the calculation unit of the sensor system is designed to ensure a continuous flow of material based on: to calculate a difference between a delivery quantity (e.g. the quantity supplied to the road paver by the one or more trucks) and a remaining filling quantity in the road paver, the difference being based on an applied area and / or an applied
  • Embodiments of the present invention are based on the knowledge that starting from a known delivery quantity (e.g. a tonnage) and determining the remaining filling quantity (the delivery quantity) in the paver, it can be determined how much material has already been applied by the paver in the relevant time window so that, based on this consideration, the amount applied can already be determined in terms of weight or volume. Knowing the distance covered, the volume of material applied per route can be determined. Alternatively, it would also be possible to relate the material volume to the applied surface, knowing the distance covered and the screed width used. In order to determine the remaining amount of asphalt in the paver as precisely as possible, various measuring measures are carried out in accordance with the exemplary embodiments. The asphalt residue in the paver is divided into three areas: "Bucket", “Tunnel” and "Area in front of or under the screed".
  • the volume of material in the tunnel is known based on the geometry of the tunnel.
  • further parameters such as the fill level and the screed width (a variable screed width in the case of Vario screeds) are calculated in addition to the geometry of this area.
  • the material volume in the bucket can be determined on the basis of the known geometry of the bucket and by determining the filling level in the bucket. With this approach, it is advantageous if the asphalt supplier typically communicates the delivery quantity with the asphalt so that a conclusion can be drawn about the material used by precisely determining the current fill level.
  • the material flow can be determined using quantities that can be reliably determined using measurement technology, with no special material flow sensors or the like being required.
  • the material volume in the area of the screed can also be determined based on the determined screed width, a determined layer thickness, according to exemplary embodiments and a known plank length can be calculated.
  • a height sensor for the screed is used for this purpose, for example.
  • the determination of the screed width in particular in the case of a variable screed width, also serves to determine, in combination with the determination of the distance, the area that has been covered since the start of the measurement.
  • the delivery quantity is determined on the basis of the supply of external information, e.g. B. by the supplier.
  • This supply can take place, for example, by means of a digital delivery note, by means of manual input or by means of a server query.
  • the continuous material consumption for. B. after the filling process, can be determined until the next filling process.
  • the distance covered in this time window is then relevant for this.
  • the material consumption can also be determined over the entire route, so that a majority (i.e. the sum) of the delivery quantities is included in the calculation.
  • the calculation of the material consumption during the filling process is calculated or interpolated on the basis of previous material consumption values.
  • the filling process can be easily recognized by the machine from the hopper cover (position of the hopper side walls).
  • the filling quantity can be verified as to whether the prognosis based on the interpolation is correct, in that the current remaining filling quantity is calculated and this is compared with the current measured values or calculations for the remaining quantity.
  • the calculation unit comprises an additional control unit which is designed, based on the determined continuous material consumption by comparison with a predetermined continuous target consumption, a control variable for controlling the construction machine, such as. B. to determine the screed of the construction machine.
  • the sensor system comprises at least one level sensor in the area of the screed or one level sensor in the area of the bucket, but preferably both level sensors, and the sensor system can also include a sensor for determining the width of the screed.
  • the fill level sensors are preferably implemented by means of 3D cameras, a laser scanner, a radar scanner or a simple ultrasonic sensor.
  • a cable pull sensor or the like can be used as the screed width sensor.
  • a distance sensor for example a laser distance sensor, with which a distance between the screed side parts (side plates) can be measured is also conceivable.
  • Another exemplary embodiment relates to a road finisher with a sensor system and preferably with a sensor system that includes a control device.
  • the method relates to the calculation of material consumption for a road paver, according to which a continuous material flow is calculated on the basis of a difference between the delivery quantity and the remaining filling quantity in the road paver, this difference being related to a distance covered and / or an area covered.
  • the remaining filling quantity can be calculated using the sum of "Material volume in the tunnel of the road paver, the material volume in the tunnel being calculated on the basis of the known geometry of the tunnel of the road paver”;”Volume of material in the area of the screed of the road paver, whereby the volume of material in the area of the screed is determined on the basis of a Screed width and a determined filling height is calculated ";and” Material volume in the paver bucket, the material volume in the bucket being calculated on the basis of a known bucket dimension and a determined fill level ".

  • the asphalt material stored in the bucket 10k is conveyed through the tunnel 10t into the area 12b of the screed 10b.
  • a screw 12s for example, is used for this purpose.
  • this can be designed in two parts, namely by a first partial area between the screed 10b and the auger 10s, which is arranged at the end of the tunnel 10t at the level of the chassis 10f. This area is marked with the reference symbol 12b1.
  • the second part of the area 12b which is marked with the reference number 12b2, is located under the screed, i.e. H. that is, between the area 12b1 and the path trigger point 12w.

  • the respective remaining quantities can be determined with the help of machine parameters and measured values that are generated by appropriate measuring systems.
  • the path trigger point 12w is the point at which a current calculation of the amount of asphalt used is carried out. This is also the reason why the area of the screed 12b is subdivided into the two sub-areas 12b1 and 12b2.
  • a typical distance between the path trigger points is 1 m and can vary (be reduced or increased) depending on the application.

  • Volume values are calculated with the measurement data obtained in this way.
  • the density of the asphalt is used to determine the asphalt tonnage or the remaining quantity in tons.
  • the consideration in relation to the volume has the background that the remaining amount can preferably be calculated as a volume value.
  • this residual amount can of course also be converted into a weight value, so that the above formula is also valid for weight values.
  • the density parameter can be verified and / or readjusted via further optional calculation steps to determine the tonnage applied.
  • a value that describes the distance covered from the start of paving or from the start of calculation is used. This value corresponds to the distance covered from the reset. Alternatively, of course, the value can also be determined differently by measurement, e.g. B. by evaluating position information.
  • the width of the built-in road is also used as an additional calculation parameter.
  • the width of the paved road corresponds to the plank width, so that this value can be used.

  • all sensors 24a to 24d as well as the screed width sensor can occur in combination in a preferred embodiment, wherein the measuring system can also be implemented with only individual or only one of these sensors mentioned. All sensors 24a to 24d and the screed width sensor (not shown) deliver its sensor signal to the evaluation unit 22, which then determines the remaining amount as referring to Figure 1b explained, calculated.
  • the device 22 can either calculate the remaining amount in relation to the volume or also convert it into the weight.
  • the volume density of the built-in material is then used for this. At this point it should be noted that this can initially be assumed and can be determined more and more precisely during installation.
  • the built-in spatial density is determined by the system. The following is a detailed description of the calculation of the remaining amount with reference to the Figures 3a to 3c received.
  • the remaining amount in the tunnel 10t can be determined according to a variant as follows:
  • the tunnel has fixed geometric dimensions, so that by measuring the fill level, it is possible to calculate the amount of material in the tunnel 10t.
  • the transport speed of the material does not have to be taken into account in this measurement.
  • Fig. 3a shows a screed 10b in a side view, with material 11 being conveyed out of the tunnel (not shown) in the area in front of the screed 12b1 by means of the screw 10s.
  • the screed smooths this material 11 from the area 12b1 into the area 12b2. The result is that a material layer 11s remains with a layer thickness 11d.
  • Figure 3b illustrates on the one hand how the filling level can be determined by means of the sensor 24c in the area 12b.
  • the sensor 24c is attached in front of the screed 10b, ie in the area 12b1.

  • the sensor 24d (for example an ultrasonic sensor or comparable) is attached to the screed in such a way that it determines the distance from the applied layer 11s.
  • Figure 3c illustrates the screed 10b in the longitudinal view in combination with a screed width sensor 24e. This can determine the variable screed width, which is used to pave roads of different widths, for example via a cable pull or a distance sensor (laser distance sensor) or similar.
  • the calculation of the amount of material in the plank area 12b is based on measurements of the plank width (cf. Figure 3c ), the layer thickness 11d (see FIG. 2b) and the material height in front of the screed 10b (see FIG. 2b).
  • the distribution of the material in the cross section can be irregular, at least in the area 12b1, as in FIG Figures 3a and 3b is illustrated.
  • Fig. 3d illustrates a bucket 10k with a material 11.
  • the bucket 10k adjoins the tunnel 10t so that the material in the lower region of the bucket 10k can flow into the tunnel 10t or can be conveyed in the same by weight.
  • the bucket 10k has a maximum filling quantity which is defined by the geometry.
  • the amount of material 11 in the bucket 10k can be determined via the geometric parameters, such as diameter or base area x filling level, the filling level being able to be determined by means of the sensor 24a. This can be, for example, an ultrasonic sensor that is directed at the surface 11o of the material 11.
  • the bucket 10k can generally be closed by means of a lid 10kd, the bucket being open during the filling process.
  • the material filling level in the bucket 10k is preferably only determined while the bucket is closed by means of the cover 10kd.
  • this variant describes the filling process in general, although the following deviation can be made for the first filling process:
  • the current asphalt consumption cannot yet be determined based on the remaining amount in the paver and the amount of asphalt delivered. This applies in particular when approaching the construction site at the start of work.
  • the installed tonnage must be determined via the volume and the delivered material density (bulk density).
  • the bulk density is assumed to be known.
  • the volume in turn is calculated using the built-in distance, the plank width and the layer thickness.
  • a transition function can be used to switch to the tonnage calculation using the remaining quantity.
  • the current consumption can be calculated as follows.
  • ET1 T1 - R1 / s, where T1 is the filling quantity of filling 1, R1 the remaining quantity prevailing at time T and s the distance covered since the restart.
  • the calculation illustrated here continues over the entire distance or all fillings and intermediate windows.
  • the built-in area is obtained relatively easily by measuring the distance using GPS or distance information from the paver and a width measurement system that is installed directly on the screed.
  • the table shows the percentage error for the total installed tonnage with different assumed residual quantity errors that arise due to system-related inaccuracies for the residual quantity determination. It can be clearly seen that the total error in the tonnage decreases significantly as the number of trucks increases. This is simply explained by the fact that ultimately the truck loads measured with calibrated scales are added up in the system. The respective residual quantity error for the total installed asphalt tonnage (total of the truck loads since the start of work) then no longer relates to the respective truck that hands over its asphalt tonnage to the paver, but to the total of the installed tonnage.
  • Fig. 5 shows the consumption ET is integrated over the path s, which is compared with the target consumption ET setpoint.
  • the diagram also shows the actual consumption in kilograms per meter and the actual consumption in kilograms per square meter. Both curves are essentially parallel, although they are only approximately constant. What is based on the comparison ET is recognizable with the two illustrated consumption per meter and per square meter, varying the instantaneous consumption resulting from temporarily varying Isttexs Western ET. From a mathematical point of view, the instantaneous consumption is the derivation of the consumption ET is according to the distance covered or the area applied.
  • the system comprises a central computer 22 which is connected to an optional control panel (generally user interface) 23 via a CAN bus, for example.
  • the central computer 22 receives as input values a screed width value from the screed width sensor 24e, a layer thickness value from the layer thickness sensor 24d, fill level information from the fill level sensor in the area of the screed (see sensor 24c) and the fill level in the tunnel from sensor 24b and the fill level in the bucket from sensor 24a.
  • parameters of the paver such as B. a current screed position or the like can be used (cf. input parameter 25a). Since, as explained above, the filling level in the bucket is preferably only determined when the bucket is not being filled, information about "bucket open” or "bucket closed” can be obtained from the bucket lid (see reference number 25b).
  • the asphalt spatial density obtained in this way can now be used in a feedback branch for more precise determination of the remaining quantity. This means that you have a self-optimizing system for determining the remaining quantity and ultimately also the spatial density.
  • This uplink branch is in Figure 8a illustrated.
  • the amount applied can be determined based on the distance covered (GNSS + driving signal) or the width of the screed.
