Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of data processing technology, and in particular to a method, device and electronic equipment for longitudinally dividing vehicles. Background Art
[0002] At present, the mileage of open roads in my country is increasing year by year, but the road traffic safety situation is still not optimistic. Among them, the safety problems caused by overloaded freight vehicles are still prominent. The use of information technology to control overload has become the main way for my country to control overloaded freight. Among them, the highway section weighing mode has become a development hotspot. It breaks the convention that the original weighing equipment can only be used for weighing vehicles in a single lane. Multiple weighing equipment is used to automatically weigh vehicles passing through the highway section. Using this mode, there is no need to build a separate overload detection station, which can not only save construction costs and human resources, but also has outstanding results.
[0003] Narrow bar pressure sensors and coil sensors are commonly used sensors in highway section weighing systems. The two types of sensors work together to achieve dynamic weighing of vehicles. The narrow bar is installed on the highway roadbed in a fixed position, and the upper surface is flush with the road surface. When a vehicle passes over the narrow bar, it will cause the corresponding narrow bar to deform. The deformation can be used to infer the pressure on the narrow bar (also including the trigger position and the maximum pressure), and then the wheel weight can be inferred. The coil sensor is installed at the entrance and exit of the narrow bar weighing area. When a vehicle passes over the coil, the coil senses that there is a vehicle above and will give a trigger signal. When the vehicle leaves, the trigger signal disappears. The coil sensors at the entrance and exit are combined to determine the longitudinal position of the vehicle relative to the weighing area.
[0004] Following a vehicle is a challenging scenario commonly faced by multiple weighing devices in the existing highway section weighing mode. Under this condition, the reliability of the coil sensor used for longitudinal vehicle separation is reduced, which increases the difficulty of longitudinal vehicle separation.

[0052] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects described may be practiced without these specific details.
[0053] See also Figure 1 and Figure 2 , is a flow chart of a method for longitudinally dividing a vehicle provided by an embodiment of the present disclosure, such as Figure 1 As shown, the method mainly includes:
[0054] S101, obtaining all measurement objects corresponding to the target vehicle in a waiting-to-depart state.
[0055] The highway section weighing system mainly relies on coil sensors to perform longitudinal vehicle separation. When the area where the coil sensors are deployed is congested, the vehicle speed slows down, the longitudinal spacing decreases, etc., the front / rear coils will be frequently triggered and extinguished. Figure 2 , when the first vehicle (vehicle 1) has not completely left the weighing area, the second vehicle (vehicle 2) may have already pressed the first few rows of narrow sensors (measurement objects), which will bring great challenges to the on-site vehicle division logic, and may cause errors in vehicle division and axle number, leading to large weight deviations and affecting the accuracy of the highway section weighing system. For this reason, the distribution of measurement objects needs to be reset.
[0056] The measurement object can be Figure 2 The narrow strip sensor described in the figure may also be other similar sensing devices, and the specific style of the measured object is not limited here.
[0057] The waiting vehicle state is when the target vehicle has not yet left the sensing area (for example, Figure 2 The weighing area shown in the dotted box), when the rear coil is still not extinguished, another vehicle from the rear enters the sensing area and triggers the front coil. At this time, the vehicle in front enters the waiting state, that is, when the rear vehicle (for example, Figure 2 After the vehicle 2 in the measurement area (sensing area), the preceding vehicle (for example, Figure 2 The vehicle 1) in the measurement area changes to the waiting state; the vehicle changes to the departure state after leaving the measurement area. Figure 2 After vehicle 1 enters the waiting state, for the newly triggered narrow strip within the vehicle boundary, no vehicle is directly put in, but a new vehicle is reassembled. Since both vehicles are in the sensing area during this period, some of the narrow strip sensors in the newly assembled vehicle 2 belong to vehicle 1.
[0058] In order to distinguish whether the signal caused by the measurement object belongs to the target vehicle (e.g. Figure 2 1) or a following vehicle of the target vehicle (e.g., Figure 2 For vehicles 2), it is necessary to first obtain all measurement objects in the sensing area.
[0059] S102: Determine a plurality of coordinate points of the measurement object in a two-dimensional coordinate system based on trigger information generated by the target vehicle and the following vehicle for the measurement object.
[0060] In order to distinguish whether the trigger signal generated by the measurement object is caused by the target vehicle or the following vehicle, a two-dimensional coordinate system related to the measurement object can be constructed. Specifically, the time sequence of the target vehicle and the following vehicle passing the measurement object can be obtained, so as to form a first sequence based on the time sequence. For example, the first time to pass the measurement object can be set to the number 1 in the first sequence, and the second time to pass the measurement object can be set to the number 2 in the first sequence, and so on, to form a first sequence. For example, if the target vehicle and the following vehicle trigger the measurement object 8 times in total, the sequence {0,1,2,3,4,5,6,7,8} can be set as the first sequence.
[0061] At the same time, the row numbers of all the measurement objects on the narrow strip layout can be obtained to form a second sequence. The row number can be obtained by mapping the number of the measurement object through a certain rule. Finally, the two-dimensional coordinate system is formed with the first sequence as the horizontal coordinate and the second sequence as the vertical coordinate. By constructing a two-dimensional coordinate system, the trigger signal of the measurement object can be effectively described based on time and the row number of the measurement object.
[0062] After the two-dimensional coordinate system is established, the time sequence value when the target vehicle or the following vehicle passes the measurement object and the number value of the measurement object can be further obtained; based on the time sequence value and the number value, the coordinate value of the measurement object in the two-dimensional coordinate system is determined, so as to form a coordinate point based on the coordinate value, forming a Figure 3 The schematic diagram of the car division is shown.
[0063] S103, performing a linear regression operation on the plurality of coordinate points to obtain a linear regression line.
[0064] After obtaining multiple coordinate points on the two-dimensional coordinate system, linear regression operations can be performed on the multiple coordinate points. For example, linear regression can be performed using the least squares method. The least squares method is actually called the least square method, which is an optimization technology for data fitting. In essence, it uses the square of the minimum error to find the best matching function for the data. In this patent, specifically, a straight line is found so that the total deviation from all points in the two-dimensional image to the straight line is minimized. In the two-dimensional plane, the least squares formula is as follows, see Figure 3 , x, y are the horizontal and vertical coordinates, a and b are the slope and intercept of the line in the plane. The regression line can be calculated by the following formula:
[0065]
[0066]
[0067] S104: Allocate the measurement object to the target vehicle or a following vehicle adjacent to the target vehicle based on the linear regression line.
[0068] After obtaining the regression line, the measurement objects can be assigned to the target vehicle or the following vehicle based on the regression line. Figure 3 In the example, the first coordinate set contained above the regression line can be obtained; the measurement object set corresponding to the first coordinate set can be confirmed as the measurement object corresponding to the target vehicle. The second coordinate set contained below the regression line can be obtained; the measurement object set corresponding to the second coordinate set can be confirmed as the measurement object corresponding to the following vehicle.
[0069] By adopting the method in this embodiment, the triggering order and row number of the narrow strip sensors are converted into two-dimensional coordinates, and the least square method is used to fit the straight line for dividing the vehicles, so that the vehicle division operation can be performed quickly and accurately.
[0070] According to a specific implementation method of an embodiment of the present disclosure, obtaining all measurement objects corresponding to the target vehicle after it is in the waiting-to-depart state includes: obtaining the measurement objects experienced by the target vehicle in a preset measurement area within a time range from entering the waiting-to-depart state to the departing state, so as to obtain all measurement objects corresponding to the target vehicle after it is in the waiting-to-depart state.

[0073] S402, forming a second sequence based on the location attributes of all the measurement objects;
[0074] The position attribute may be the row numbers formed when the measurement objects are arranged in rows or columns, and the second sequence is formed by the sequence numbers of these row numbers.
