The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
First, an application scenario to which the present application is applicable will be described. The method can be applied to a road vehicle weighing scene, but it should be understood that the road scene is only used as an example in the embodiment of the present application, but the application scenario of the vehicle weighing system of the present application is not limited thereto.
The technical scheme is mainly applied to weighing vehicles running on the highway, and is particularly suitable for scenes with high running speed of vehicles such as expressways and the like.
The traditional vehicle weighing system is mainly composed of a plurality of transversely arranged strip-shaped weighing sensors, and the weighing system has higher speed limit on vehicles. Meanwhile, due to the fact that a gap exists between the sensor and the edge of the road, abnormal conditions of missed vehicle weighing detection and large weighing deviation can occur when running modes which are not standard, such as cross-lane running, edge pressing running and seam pressing running, face to the vehicle.
In order to overcome at least one of the above defects, embodiments of the present application provide a vehicle weighing system, which can accurately weigh a vehicle traveling at a high speed without increasing the overall complexity of the system.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a vehicle weighing system according to an embodiment of the present disclosure. As shown in fig. 1, the vehicle weighing system provided by the embodiment of the present application includes a plurality of weighing components arranged in a weighing area 1, where the weighing area 1 refers to a range where the weighing components are mounted on a road surface for weighing a vehicle. The weighing area 1 comprises at least one driving lane, a weighing assembly is arranged in each driving lane, and each weighing assembly comprises a plurality of strip-shaped weighing sensors 4.
Here, the bar-type load cell 4 is used to measure the wheel load of the vehicle, and when the wheel is pressed against the bar-type load cell, the bar-type load cell generates and transmits the vehicle weight information to the outside. For example, the vehicle weight information detected by the bar-type load cell may refer to the wheel load of the vehicle.
For each driving lane, a plurality of strip-shaped weighing sensors 4 are arranged in a staggered manner in the driving lane along the driving direction to form a first sensing array and a second sensing array, and the first sensing array and the second sensing array are respectively used for measuring the wheel loads of wheels at two ends of one axle.
The first side of each strip-shaped weighing sensor 4 in the first sensor array coincides with the first side 2 of the driving lane and the second side of each strip-shaped weighing sensor 4 in the second sensor array coincides with the second side 3 of the driving lane. Here, the first side of the weighing bar-shaped sensor 4 and the second side of the weighing bar-shaped sensor 4 are opposite sides, the first side 2 of the driving lane and the second side 3 of the driving lane are opposite sides, and the first side 2 of the driving lane and the second side 3 of the driving lane may be shoulders on the left and right sides of a single-lane road or boundaries on the left and right sides of each lane of a multi-lane road.
Referring to fig. 2, fig. 2 is a second schematic structural diagram of a vehicle weighing system according to an embodiment of the present disclosure.
As shown in fig. 2, the second side of each weighing strip sensor 4 in the first sensing array is close to the center line 21 of the driving lane, and the first side of each weighing strip sensor 4 in the second sensing array is close to the center line 21 of the driving lane, where the center line 21 of the driving lane refers to a center line formed by a set of points of the driving lane with equal distance from the left and right side boundaries, and the center line is not a solid line in the lane, but is a virtual line for describing the arrangement of the weighing strip sensors 4.
It should be understood that the above-mentioned center line 21 close to the driving lane may mean that one side of the strip-shaped load cell 4 coincides with the center line 21 of the driving lane, or that the vertical distance between one side of the strip-shaped load cell 4 and the center line 21 of the driving lane is smaller than a set distance value, where the set distance value may be determined according to actual conditions, and the application is not limited thereto.
That is to say, every bar weighing sensor 4 in the first sensing array can cover a plurality of bar regions of the first side 2 of lane of traveling to the correspondence between the central line 21 on lane of traveling, every bar weighing sensor 4 in the second sensing array can cover a plurality of bar regions of the second side 3 of lane of traveling to the correspondence between the central line 21 on lane of traveling, and like this, can realize weighing sensor to the complete coverage on lane, when avoiding because of the vehicle carries out the running of blank pressing, line ball travel when the non-normative mode of traveling such as, the whole wheel load of the vehicle that weighing sensor can't gather, lead to the vehicle to weigh lou to examine, the big abnormal conditions of deviation.
Alternatively, the straight-line distance from the second side of each strip-shaped load cell 4 in the first sensor line 2 to the first side of each strip-shaped load cell 4 in the adjacent second sensor line 3 is equal, and here, the straight-line distance may be as shown in fig. 2, which should be understood as the arrangement pitch 31 between two strip-shaped load cells 4 adjacent in the front-rear direction in the longitudinal direction in the vehicle traveling direction. Like this, the time interval at which the adjacent bar-shaped weighing sensors 4 send out the vehicle weight information is equal, and the dispersion of the vehicle weight information sent out by the plurality of bar-shaped weighing sensors 4 can be reduced.
That is, the bar-shaped load cells 4 in each sensing column may be arranged at equal intervals, and the bar-shaped load cells 4 in two adjacent sensing columns are also arranged at equal intervals.
Further, the linear distance between the strip-shaped weighing sensors 4 and the number of the strip-shaped weighing sensors contained in each sensing column can be adjusted according to actual conditions. The existing weighing system has high speed limit on vehicles, and the vehicles are mostly required to greatly reduce the speed when entering a weighing area, so that traffic jam can be caused. For the situation, in the lane with higher speed limit of the road, the linear distance between the strip-shaped sensors can be correspondingly increased, or the number of the strip-shaped weighing sensors contained in each row is increased, so that the effective weighing area is increased. Meanwhile, by increasing the distance between the sensors, the triggering interval of the symmetrical retransmission sensors of the left wheel and the right wheel of the same axle can be increased, the subsequent calculation pressure when a vehicle weighing result is generated is reduced, and the calculation accuracy is improved.
Optionally, each strip-shaped weighing sensor 4 in the first sensing row of any one of the driving lanes is arranged in a staggered manner with each strip-shaped weighing sensor 4 in the second sensing row of the driving lane adjacent to the any driving lane.
Therefore, when the vehicle runs in the middle of two adjacent lanes, namely when the vehicle runs across lanes, the second sensor array of the left lane and the first sensor array of the right lane can measure the wheel loads of the wheels on two sides of the vehicle, and then the vehicle running across lanes is weighed.
Referring to fig. 3, fig. 3 is a third schematic structural diagram of a vehicle weighing system according to an embodiment of the present disclosure. As shown in fig. 3, the vehicle weighing system further includes a first induction coil 5 and a second induction coil 6, the first induction coil 5 is disposed at a vehicle-entering position of the weighing area 1, and the second induction coil 6 is disposed at a vehicle-leaving position of the weighing area, where the induction coils emit an induction signal outward for judging a position when the vehicle enters and leaves the weighing area when the vehicle passes over the induction coils. A coil set is formed by a first induction coil 5 and a second induction coil 6, at least one coil set being arranged in each lane. And positioning the driving route of the vehicle through the coil group in the lane.
Further, a first coil group and a second coil group may be further arranged within each travel lane, the first induction coil 5 in the first coil group being arranged at a vehicle-entering position corresponding to the first train of the travel lane, the second induction coil 6 in the first coil group being arranged at a vehicle-leaving position corresponding to the first train of the travel lane, the first induction coil 5 in the second coil group being arranged at a vehicle-entering position corresponding to the second train of the travel lane, the second induction coil 6 in the second coil group being arranged at a vehicle-leaving position corresponding to the second train of the travel lane, for each travel lane. Therefore, when the vehicle runs across lanes as described above, the second coil group and the first coil group of the adjacent lane can send out induction signals to the outside, so that the condition that the vehicle passes through a weighing area in a special running mode of running across lanes is judged, and the weighing accuracy is improved by combining the vehicle weight information of the strip-shaped weighing sensor on the vehicle running route.
Optionally, a plurality of grooves are provided on each driving lane, and each induction coil and each strip-shaped weighing sensor are arranged in the corresponding groove. Like this, set up induction coil and bar weighing sensor's main part in the recess, can reduce and even eliminate the difference in height of sensor and road surface to reduce jolting of vehicle when weighing, make the vehicle keep original speed of a motor vehicle when weighing, improve weighing efficiency.
Illustratively, in actual use, the first sensing column and the second sensing column each include three strip load cells to cope with most usage scenarios.
Referring to fig. 4, a brief description is provided below of a working flow of the vehicle weighing system with reference to fig. 4, and fig. 4 is a fourth schematic structural diagram of the vehicle weighing system according to the embodiment of the present application. As shown in fig. 4, the weighing area of the vehicle weighing system covers two adjacent driving lanes, wherein the lane corresponding to the first magnetic induction coil A, B and the second magnetic induction coil C, D of the weighing assembly on the left side in the figure is lane X. The first sensor column and the second sensor column of the weighing assembly located in the lane X each contain three strip-shaped weighing sensors 4. The lane corresponding to the first magnetic induction coil E, F and the second magnetic induction coil G, H of the weighing assembly on the right side in the figure is a lane Y, and the first sensing column and the second sensing column of the weighing assembly located in the lane Y respectively comprise three strip-shaped weighing sensors 4.
When the vehicle normally runs through the lane X, the coil assembly formed by the first magnetic induction coil A and the second magnetic induction coil C induces that the left part of the vehicle runs through, and the coil assembly formed by the first magnetic induction coil B and the second magnetic induction coil D induces that the right part of the vehicle runs through, so that the vehicle route is identified. Specifically, when the vehicle enters the weighing area from the lane X in the traveling direction, the first magnetic induction coil A, B senses that the vehicle passes through and sends out a vehicle entering sensing signal; when the vehicle runs out of the weighing area along the driving direction from the lane X, the second magnetic induction coil C, D induces the vehicle to pass through, and sends out a vehicle-out induction signal, so that the system can judge that the vehicle runs along the path from the magnetic induction coil A, B to the magnetic induction coil C, D, and further obtain that the vehicle runs normally along the lane X, and further select to read the vehicle weight information sent by the strip-shaped weighing sensors 4 in the corresponding sensing columns, and obtain the wheel load of each wheel. And adding the wheel loads of wheels at two ends of one axle to obtain the axle weight of the axle, and adding the axle weights of all the axles of one vehicle to obtain a final vehicle weight measurement result.
When the vehicle runs across the X, Y lane, the combination of the first magnetic induction coil B and the second magnetic induction coil D induces the left part of the vehicle to run through, and the combination of the first magnetic induction coil E and the second magnetic induction coil G induces the right part of the vehicle to run through, so that the vehicle route is recognized. Specifically, when the vehicle travels across lanes and enters the weighing area between the X lane and the Y lane, the first magnetic induction coil B, E senses that the vehicle passes through and sends out a vehicle entering sensing signal; when the vehicle crosses the lane and passes through the X lane and the Y lane to exit the weighing area, the second magnetic induction coil D, G senses the passing of the vehicle and sends an exit sensing signal outwards, so that the system can judge that the vehicle runs along the path from the magnetic induction coil B, E to the magnetic induction coil D, G, namely, the crossing lane X, Y is abnormally driven. Therefore, the vehicle weight information sent by the bar-shaped weighing sensors 4 in the corresponding sensing columns is selected to be read, and a vehicle weight result is obtained.
Therefore, the weighing accuracy and stability of the vehicle weighing system are further improved by the combined arrangement mode of the weighing sensor and the coil group.
Optionally, the vehicle weighing system further comprises a processing device connected to each of the strip load cells and to each of the induction coils to receive the collected vehicle weight information from each of the strip load cells and to receive the induction signal generated by the vehicle passing by from each of the induction coils.
In practical use, when multi-channel millisecond-level transmission signals generated by a vehicle running at a high speed are processed, the single-core processing device has the probability that full-load work or even overload work occurs, so that the conditions of shaft loss, abnormal weight and the like of the vehicle are caused, and the dispersion of weighing data is larger. In order to solve the above-mentioned defects, an embodiment of the present application provides a processing apparatus. Referring to fig. 5, fig. 5 is a schematic structural diagram of a processing device according to an embodiment of the present disclosure.
