Description

Technical Field

[0001] The present invention relates to the field of ETC technology, and in particular to an anti-freeloading intelligent payment control method and device. Background Art

[0002] At present, ETC (Electronic Toll Collection) technology is an electronic non-stop toll collection system. It uses wireless communication and automatic identification technology to realize a convenient way to pay fees without stopping when passing through traffic toll stations. At present, the mainstream ETC system is mainly composed of vehicle automatic identification system, central management system and other auxiliary facilities. Among them, the vehicle automatic identification system mainly includes OBU (On board unit) and RSU (Road side unit). OBU stores relevant information of the vehicle and is generally installed on the front windshield of the vehicle. RSU is installed next to the toll station. The central management system stores a large amount of information on registered vehicles and owners. When a vehicle enters the toll station, RSU will communicate with the OBU on the vehicle, automatically identify the vehicle information through wireless radio frequency identification technology, and deduct the relevant traffic fees from the user's pre-set account. The owner can quickly pass through the toll station without stopping and paying manually, truly realizing a smooth journey.

[0003] However, the ETC system often has the problem of missed detection in actual application, which leads to the problem of "freeloading" (also known as toll evasion). The common way of freeloading is: the front car (without OBU installed) waits for an opportunity to move on the side of the lane. Once the ETC system identifies the rear car (with OBU installed), the front car suddenly starts or accelerates to "squeeze in" and enters the ETC lane, thereby entering / exiting the highway through the gate boom and evading tolls. There are currently two main ways to solve this "freeloading" problem: 1. Install a license plate recognition system at the gate lift bar, and only lift the lift bar when the license plate matches to avoid this type of car-scrambling problem: To avoid a few behaviors, every vehicle must undergo license plate recognition when passing through the gate, which will inevitably affect the vehicle traffic rate and reduce traffic efficiency; 2. Reduce the "squeeze-in" space, that is, shorten the distance between the roadside unit and the lift bar: Since the ETC system takes a certain amount of time from the roadside unit identifying the on-board unit to the gate lift bar lifting after the toll is successfully deducted, forcibly reducing the "squeeze-in" space causes vehicles to stop and wait, greatly affecting the travel experience of the installed vehicles. Summary of the invention

[0018] It is worth noting that the methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products, and their sources are not specifically limited unless otherwise specified.

[0019] Example 1 See also Figure 1 , 2, when a first vehicle equipped with a vehicle-mounted unit passes through a first position, first measurement information is obtained; the roadside unit identifies the vehicle-mounted unit to obtain vehicle information, and the charging unit outputs a charging signal according to the vehicle information; the first measurement information includes a first moment, which is the moment when the first vehicle passes through the first position; preferably, to facilitate subsequent calculations, the first vehicle passing through the first position is when the front of the first vehicle passes through the first position along the driving direction; Preferably, the first measurement information can be obtained through roadside video equipment, which includes high-definition cameras, gun-type cameras, panoramic cameras, and video radar integrated devices, etc. In addition to obtaining the first moment, it can also be used to wake up the roadside unit; the second measurement information is obtained when the vehicle passes the second position; the second measurement information includes the second moment, and the second moment is the moment when the vehicle passes the second position; the vehicles corresponding to the second measurement information are all vehicles passing the second position including the first vehicle; when all vehicles are driving normally, each first vehicle equipped with a vehicle-mounted unit passes the first position first and then the second position; the distance between the second position and the landing pole is smaller than the distance between the first position and the landing pole; preferably, to facilitate subsequent calculations, the vehicle passing the second position means that the front of the vehicle passes the second position along the driving direction; Similar to the first measurement information, preferably, the second measurement information can also be obtained through a roadside video device, and the roadside video device used to obtain the second measurement information does not need to have a function of waking up the roadside unit; Obtaining a preset distance and a first preset time; obtaining a third moment according to the second moment and the first preset time; Obtaining a calculated distance at a third moment according to the first moment, the second moment, the preset distance and the first preset time; the calculated distance is the distance from the landing gear to the first vehicle; See also Figure 7 , the preset distance includes a first preset distance D a and the second preset distance D b ; The first preset distance D a is the distance from the landing rod to the first position, and the second preset distance D b is the distance from the first position to the second position; The steps to obtain the calculated distance are: Acquire a first preset distance and a second preset distance; The preceding travel time is obtained according to the first moment and the second moment; that is, when the vehicles corresponding to the first moment and the second moment are both the first vehicle, the preceding travel time is the time taken by the first vehicle to travel from the first position to the second position on the lane along the travel direction, that is, the first vehicle; through the second preset distance D b time; The average speed of the first vehicle is obtained according to the second preset distance and the previous driving time, that is, the average speed is calculated by distance and time; when the first vehicle passes through the roadside unit, that is, the first position, in order to ensure that the roadside unit recognizes the vehicle-mounted unit, the vehicle speed is generally required to be about 20 km / h. Due to different driving habits, the acceleration and deceleration conditions of each vehicle before passing the lift bar are different, and the vehicle speed is not uniform; The latter driving distance is obtained according to the average speed and the first preset time. Taking into account objective factors such as network and data transmission lag, the vehicle is buffered for the first preset time after passing the second position, that is, the measured distance and the calculated distance are obtained at the third moment to ensure the reliability of the data. The first preset time is 1 to 5 seconds, preferably 3 seconds. After the second position, the distance traveled by the vehicle at the average speed within the first preset time is the latter driving distance. The latter driving distance is: The calculated distance is obtained according to the first preset distance, the second preset distance and the latter driving distance, and the calculated distance is: Where D a is the first preset distance, D b is the second preset distance, D3 is the latter driving distance, t a is the first preset time, t1 is the first moment, and t2 is the second moment.

[0020] In addition, obtaining the calculated distance can also be achieved by speed measurement. Specifically, the second measurement information can also include a second speed, that is, the second speed is the speed at which the vehicle passes the second position, and the latter driving distance within the first preset time is obtained by the second speed, thereby obtaining the calculated distance; Obtaining the measured distance at the third moment, where the measured distance is the distance from the landing boom to a vehicle near the boom, where the vehicle near the boom is a vehicle that has not passed through the landing boom and is closest to the landing boom; preferably, a distance sensor is arranged in the middle of the landing boom, and the distance from the landing boom to the vehicle near the boom is measured at the third moment by the distance sensor; Get the distance criterion; the distance criterion is: |D1-D2|<D0; Wherein, D1 is the measured distance, D2 is the calculated distance, and D0 is the third preset distance; When the first vehicle is driving normally, the measured distance and the calculated distance are theoretically equal. However, since the calculated distance is obtained by the average speed, there is a calculation error in the acquisition process, and there is an execution error when obtaining the measured distance. The difference between the two will also have an error. Therefore, in order to eliminate this error, a third preset distance is set. Usually, the third preset distance is 2m to 3m. Determine whether the distance criterion is established based on the measured distance and calculated distance and obtain the first judgment: When the first judgment is that the distance judgment is established, that is, the vehicle near the pole is the first vehicle, the vehicle identification is correct, and the vehicle-mounted unit is judged according to the deduction signal whether the deduction is normal and a second judgment is obtained; When the first judgment is that the distance criterion does not hold: Obtaining first license plate information; the first license plate information is the license plate information of the vehicle near the pole; Performing a first comparison between the first license plate information and the vehicle information and obtaining a third judgment; When the third judgment is that the first license plate information matches the vehicle information, the on-board unit is judged whether the deduction is normal according to the deduction signal and the second judgment is obtained; since the deduction signal is obtained after the vehicle information is obtained at the first position, the deduction signal is whether the normal deduction can be achieved instead of the real-time deduction, and there is enough execution time, and the final deduction can be carried out after passing, which is the existing technology and will not be repeated here; When the second judgment is that the vehicle-mounted unit deducts the fee normally, a lever-lifting signal is obtained according to the second judgment; The lifting lever is controlled according to the lifting lever signal to perform the lifting lever action.

[0021] See also Figure 8 When the measured distance is close to the calculated distance, that is, the distance criterion is established, there is no "cut-in" vehicle between the first vehicle and the lift pole, and the vehicle identification is correct; the vehicle can pass without stopping based on normal toll deduction; See also Fig. 9 (a) When the first vehicle has not passed the first position and the "freeloading" vehicle "cuts in" between the first position and the second position, the first vehicle can stop moving forward; See also Fig. 9 (b) The first vehicle has not passed the second position, and when the "freeloading" vehicle "cuts in" between the second position and the lift pole, the first vehicle stops moving forward. Since there is no second measurement information, the subsequent calculation and judgment cannot be completed. Therefore, the vehicle cannot pass due to incorrect identification, which can avoid the "cutting in" between the second position and the lift pole. At this time, after the "freeloading" vehicle exits the driving lane, the subsequent calculation and judgment are completed. It is worth noting that at this time, since the first vehicle has experienced a stop and restart, the first judgment may fail to establish the distance criterion. Passage can be achieved through license plate matching detection and toll deduction, that is, the third judgment and the second judgment; See also Fig. 9 (c) The first vehicle passes the second position smoothly. When the measured distance is not close to the calculated distance, that is, the distance criterion is not established, there is a vehicle "cutting in" between the first vehicle and the landing gear or there is a detection error. It is necessary to add a license plate matching detection, that is, a third judgment, to prevent freeloading. At this time, after the freeloading vehicle exits the driving lane, it can pass through the third judgment and the second judgment.

[0022] It can be seen that the present invention realizes the identification of the first vehicle and the "jamming" vehicle by adding a distance criterion without shortening the distance between the roadside unit and the lift pole, and further confirms the "jamming" vehicle through license plate matching and avoids identification errors, which can prevent most "jamming" vehicles from roaming around. At the same time, the toll signal acquisition process and the vehicle identification process effectively utilize the execution time to achieve non-stop passage, and the passage efficiency is high.

[0023] See also Figure 2 , the anti-freeloading intelligent payment control method also includes: Obtaining a time criterion and a second preset time; According to the first moment and the second moment, it is judged whether the time criterion is established and the fourth judgment is obtained: When the fourth judgment is that the time criterion is established, the preset distance is obtained to perform subsequent distance judgment, normal toll deduction and lifting of the barrier to achieve passage; The time criterion is that the first moment is earlier than the second moment, and the time interval between the second moment and the first moment is greater than the second preset time, that is, the time criterion is: In the formula, t1 is the first moment, t2 is the second moment, and t b It is the second preset time.

[0024] The vehicle passes the second preset distance D at a specified speed (about 20 km / h) b The time at which the first and second vehicles meet is the theoretical driving time t*, which is determined by the length of the second preset distance. Under the premise of ensuring "lane-in safety", the hitchhiking vehicle needs to squeeze in when the distance between the first vehicle and the second position is at least one vehicle length (the length of the squeezing vehicle). The second preset time is determined by the second preset distance and the distance of the safe squeezing vehicle, i.e., the lane-changing distance; the second preset time is: In the formula, D* is the lane change distance, usually 3 to 5 m, and v* is the specified vehicle speed, usually less than 30 km / h; The acquisition time of the second moment should be later than the second preset time of the first moment. If this condition is not met, it may be a "jamming" vehicle, and further judgment can be made; when the fourth judgment is that the time criterion is not established, the first license plate information is obtained, and the vehicle is identified through the third judgment; Still see Fig. 9 (a) When the first vehicle has not passed the first position and the "freeloading" vehicle "cuts in" between the first position and the second position, the second moment is earlier than the first moment, and the time criterion is not met; Still see Fig. 9(a) When the first vehicle has passed the first position and the "freeloading" vehicle "cuts in" between the first position and the second position, although the second moment is later than the first moment, the time interval between the two is too short to exceed the second preset time, and the time criterion is not met.

[0025] Supplementing the time criterion can further identify vehicles cutting in and avoid a wider range of vehicles being hitched. The time criterion can be used as a preliminary judgment before the distance criterion, or as a supplementary judgment to the distance criterion, greatly increasing the accuracy of vehicle identification. In addition, when the fourth judgment is that the time criterion is established, the distance criterion can be omitted and the deduction signal can be used to directly determine whether the on-board unit is deducting fees normally and obtain the second judgment. When the second judgment is that the on-board unit is deducting fees normally, the lifting bar signal is obtained based on the second judgment.

[0026] Furthermore, when the first judgment is that the distance criterion does not hold: Determine whether a rod drop signal is received and obtain a sixth judgment; When the sixth judgment is that the pole drop signal is received, it is judged according to the deduction signal whether the on-board unit deducts the fee normally and obtains the second judgment.

[0027] When the vehicle in front of the first vehicle that is also equipped with an on-board unit has not passed the lift barrier, the distance judgment criterion will not be met. In this case, it is necessary to wait for the vehicle in front to pass before passing. At this time, it is necessary to combine the payment control of the previous vehicle. If the vehicle in front is a jam-cutting vehicle, it will not receive the lift barrier signal and will need to pass through the license plate matching detection.

[0028] Further, obtaining a fourth moment, the fourth moment being the moment of obtaining the second judgment; When the second judgment is that the vehicle-mounted unit deducts the fee normally: Obtain pressure criteria; Acquiring a first pressure signal at a third position from a fourth moment, the third position being located at a position passing through the landing rod and at a fourth preset distance from the landing rod, which may be achieved by adding a pressure sensor at the fourth preset distance after passing through the landing rod; When the front vehicle passes normally, the first pressure signal is also used to obtain the pole drop signal of the front vehicle; when the front vehicle passes abnormally or there is an abnormality at the third position, in order to ensure the safety of the first vehicle, it is necessary to judge the pressure situation at the third position to ensure that there is no vehicle at the third position before the first vehicle passes; judging whether the pressure criterion is established according to the first pressure signal and obtaining a seventh judgment; When the seventh judgment is that the pressure criterion is established, a lever lifting signal is obtained according to the seventh judgment.

[0029] See also Figure 1 , 3, 11. When the first vehicle passes through a third position, obtaining a second pressure signal; Performing a third comparison between the second pressure signal and the vehicle information and obtaining an eighth judgment; When the eighth judgment is that the second pressure signal matches the vehicle information, a rod drop signal is obtained; The lifting and lowering rod is controlled to drop the rod according to the rod drop signal.

[0030] Preferably, the vehicle information includes first vehicle information and second vehicle information, wherein the second vehicle information is used for processing by the deduction unit, the first vehicle information is used to compare the second pressure signal, and the second vehicle information is for the roadside unit to identify the first vehicle and obtain the first vehicle information (such as vehicle ID, vehicle model, etc.) and payment information associated with a bank account, etc. It is a conventional ETC identification process. In the second vehicle information, the vehicle model information is extracted as the first vehicle information for obtaining the drop bar signal, and the payment information similar to that associated with a bank account only participates in the acquisition of the deduction signal but does not participate in the process of vehicle identification and obtaining the drop bar signal; in the process of the first vehicle passing through the pressure sensor, the second pressure signal is obtained by the wheel rolling pressure sensor. When the number of wheel rolling times matches the vehicle model, it indicates that the first vehicle has passed the third position, and the drop bar can be controlled to drop the bar to complete the passage.

[0031] In addition, other methods can be used to determine whether the first vehicle has completely passed the landing gear position, such as installing laser sensors on both sides of the lane at the landing gear, the laser sensor includes a transmitting end and a receiving end, one side of which is installed with the transmitting end and the other side is installed with the receiving end, and recording from the first time the body of the first vehicle blocks the receiving end until there is no obstruction indicates that the first vehicle has completely passed the landing gear position. This is a prior art and will not be described in detail here.
