Description

Obviously, the described embodiments are some, but not all, of the embodiments of this solution.

In addition, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order.
[0043] The following will describe the implementation of the present disclosure in detail with reference to specific drawings:
[0044] Figure 1 FIG. is a schematic structural diagram of an automatic toll gate lifting control system provided by an embodiment of the present disclosure. Referring to Figure 1 FIG. Figure 1 , this automatic toll gate lifting control system includes:
[0045] a central control module 101, a roadside unit 102, a vehicle verification module 103, a first sensing unit 104, a second sensing unit 105, and a drive motor 106.
[0046] The first sensing unit 104 and the second sensing unit 105 are arranged on the first side of the traffic restriction rod. The first sensing unit 104 is arranged at the toll gate entrance, and the second sensing unit 105 is arranged between the first sensing unit 104 and the traffic restriction rod. Both the first sensing unit 104 and the second sensing unit 105 include induction coils.
[0047] The central control module 101 is respectively connected to the roadside unit 102, the vehicle verification module 103, and the drive motor 106. The roadside unit 102 is respectively connected to the vehicle verification module 103 and the first sensing unit 104. The second sensing unit 105 is connected to the vehicle verification module 103. The drive motor 106 is connected to the traffic restriction bar.
[0048] The roadside unit 102 is configured to identify vehicles. The vehicle verification module 103 is configured to verify vehicles.
[0049] The central control module 101 is configured to control the working state of the drive motor 106. The drive motor 106 is configured to control the raising and lowering of the traffic restriction bar.
[0050] In this embodiment, the roadside unit 102 is configured to identify vehicles, including:
[0051] The roadside unit 102 is configured to identify a vehicle when the first sensing unit 104 detects vehicle information.
[0052] The vehicle verification module 103 is configured to verify vehicles, including:
[0053] The vehicle verification module 103 is configured to verify a vehicle when the second sensing unit 105 detects vehicle information.
[0054] The central control module 101 is configured to control the working state of the drive motor 106, including:
[0055] The central control module 101 is configured to control the working state of the drive motor 106 according to the information of the roadside unit 102 and the information of the vehicle verification module 103, which the drive motor 106 is configured to be based on.
[0056] In this embodiment, when a vehicle enters the toll station, it first passes through the inductive loop of the first sensing unit 104. When the first sensing unit 104 detects vehicle information, the roadside unit 102 starts to identify the vehicle, such as obtaining the license plate information, vehicle type, etc. of the vehicle. The roadside unit 102 transmits the identified vehicle information to the vehicle verification module 103.
[0057] The vehicle continues to move. When the inductive loop of the second sensing unit 105 detects vehicle information, the vehicle verification module 103 identifies the vehicle and verifies the vehicle by interacting with the roadside unit 102 for relevant vehicle information, such as verifying the legality of the vehicle, the payment situation, and whether it is a queue-jumping vehicle, etc. The vehicle verification module 103 transmits the verification result to the central control module 101.
[0058] The central control module 101 controls the operating state of the drive motor 106 based on the vehicle identification information of the roadside unit 102 and the verification result of the vehicle verification module 103. If the vehicle verification is passed, the central control module 101 will control the drive motor 106 to lift the restricted line bar and allow the vehicle to pass. If the vehicle verification fails, the central control module 101 will control the drive motor 106 to keep the restricted line bar in the lowered state to prevent the vehicle from passing. The drive motor 106 is connected to the restricted line bar and controls the lifting and lowering actions of the restricted line bar according to the instructions of the central control module 101.
[0059] Exemplarily, when a car drives into the toll station, it first passes through the inductive loop of the first sensing unit 104. The inductive loop can sense the magnetic field change caused by the passing of the vehicle, and then determine that a vehicle has entered. The first sensing unit 104 transmits the detected signal to the roadside unit 102, triggering the roadside unit 102 to identify the vehicle. At this time, the ETC device (usually including an on-vehicle unit and an ETC card) on the vehicle will be activated by the microwave signal emitted by the roadside unit 102. The roadside unit 102 sends an interrogation signal to the on-vehicle unit. After receiving the signal, the on-vehicle unit encrypts the vehicle information (such as vehicle license plate, vehicle type, user information, etc.) stored in the ETC card and the relevant transaction data. The on-vehicle unit sends the encrypted information back to the roadside unit 102, and the roadside unit 102 then uploads this information to the back-end system of the toll station. The back-end system verifies and processes the received information to confirm the legality of the vehicle, the balance of the ETC card, the account status, or the payment situation, etc. If the verification is passed, the back-end system sends an instruction to allow passage to the roadside unit 102. After receiving the instruction, the roadside unit 102 sends a signal to lift the bar and release the vehicle to the on-vehicle unit.
[0060] Then, when the vehicle travels to the second sensing unit 105, the vehicle verification module 103 identifies the vehicle information and matches and verifies it with the vehicle information identified by the roadside unit 102 to determine that it is the same vehicle. At the same time, it queries the payment situation of the vehicle according to the license plate information and confirms that the payment has been made. The vehicle verification module 103 sends the information that the verification is passed to the central control module 101, and the central control module 101 immediately controls the drive motor 106 to lift the restricted line bar, and the car passes through the toll station smoothly.
[0061] Exemplarily, when a vehicle attempts to cut in line, the roadside unit 102 and the vehicle verification module 103 can verify whether the vehicle in front and behind is the same vehicle through the vehicle information they respectively identify. The vehicle verification module 103 can also judge whether it is a vehicle cutting in line based on information such as the driving trajectory and time of the vehicle in the second sensing area. If it is a vehicle cutting in line, the vehicle verification module 103 feeds back the situation to the central control module 101, and the central control module 101 controls the drive motor 106 to prevent the vehicle from passing and issues an alarm to maintain the order of the toll station.
[0062] Through the collaborative work of multiple sensing units, roadside unit 102, and vehicle verification module 103, this embodiment can quickly and accurately complete the identification and verification of vehicles, reduce the residence time of vehicles at the toll station, and thus significantly improve the passing efficiency of vehicles. It avoids vehicle congestion caused by manual operation or cumbersome processes at traditional toll stations.
[0063] Specifically, the first sensing unit 104 is set at the entrance of the toll station and can sense the arrival of vehicles in advance, preparing for subsequent identification and verification work. The second sensing unit 105 is between the first sensing unit 104 and the traffic restriction bar, further refining the position detection of the vehicle, enabling the system to more precisely control the lifting timing of the traffic restriction bar and optimizing the passing process of the vehicle.
[0064] In addition, the roadside unit 102 identifies the vehicle, the vehicle verification module 103 conducts verification, and the central control module 101 controls the driving motor 106 to work according to the verification result, ensuring that only legal and compliant vehicles that have completed verification can pass through the traffic restriction bar, effectively avoiding illegal acts such as toll evasion and ensuring the accuracy of toll collection and the safety of road operation.
[0065] As Figure 2 shown, in an embodiment of the present disclosure, the vehicle verification module 103 includes a first verification unit 107 and a second verification unit 108.
[0066] The first verification unit 107 is respectively connected to the central control module 101, the roadside unit 102, and the second sensing unit 105. The second verification unit 108 is respectively connected to the central control module 101 and the first verification unit 107.
[0067] The first verification unit 107 is set in the area where the second sensing unit 105 is located.
[0068] The first verification unit 107 and the second verification unit 108 are configured to verify the vehicle.
[0069] In this embodiment, when the vehicle enters the area where the second sensing unit 105 is located, the second sensing unit 105 transmits the detection information to the first verification unit 107, activating the first verification unit 107 to identify the vehicle driving into the corresponding area. At the same time, the first verification unit 107 obtains the vehicle information identified and recorded by the first sensing unit 104 from the roadside unit 102, and determines whether the two are the same vehicle to identify illegal queue-jumping behavior. Further, a preliminary verification of the vehicle can be carried out, such as verifying the basic information of the vehicle, whether there are abnormalities, etc. The first verification unit 107 sends the preliminary verification result to the second verification unit 108, and the second verification unit 108 further conducts an in-depth verification of the vehicle, such as verifying the payment status of the vehicle, whether it complies with the traffic regulations, etc. Finally, the second verification unit 108 transmits the comprehensive verification result to the central control module 101, and the central control module 101 controls the working state of the drive motor 106 according to the result, thereby determining the raising or lowering of the traffic restriction rod.
[0070] Exemplarily, at a highway toll station, when a vehicle drives into the area of the second sensing unit 105, the first verification unit 107 obtains the vehicle information and preliminarily verifies whether the vehicle is a registered vehicle, whether it is equipped with an ETC, or whether it is a queue-jumping vehicle. Then, the second verification unit 108 verifies whether the vehicle has paid the toll. If the vehicle is normal, the central control module 101 controls the drive motor 106 to raise the traffic restriction rod, and the vehicle passes. If the vehicle has not paid the toll, the traffic restriction rod remains lowered to prohibit the vehicle from passing. For example, when a certain vehicle enters this area, the first verification unit 107 confirms that the vehicle information is correct, and the second verification unit 108 finds that the vehicle has not paid the toll. Then the central control module 101 controls the traffic restriction rod to prevent the vehicle from passing until it pays the toll and is released.
[0071] The vehicle verification module 103 of this embodiment effectively improves the accuracy and security of vehicle verification through a dual-verification mechanism. First, the first verification unit 107 preliminarily screens out illegal vehicles, and then the second verification unit 108 conducts an in-depth inspection to ensure that each vehicle meets the traffic conditions. This design not only avoids illegal queue-jumping behavior but also improves the traffic efficiency and reduces the risk of congestion and accidents caused by incorrect vehicle verification.
[0072] As Figure 2 shown, in an embodiment of the present disclosure, a toll station automatic traffic restriction rod control system further includes:
[0073] A third sensing unit 109. The third sensing unit 109 is arranged on the second side of the traffic restriction rod.
[0074] The third sensing unit 109 is connected to the second verification unit 108, and the second verification unit 108 is arranged in the area where the third sensing unit 109 is located.
[0075] In this embodiment, when the vehicle passes through the traffic restriction bar and reaches the second side of the traffic restriction bar, the third sensing unit 109 will detect the vehicle information and transmit this information to the second verification unit 108. Based on the received information, the second verification unit 108 can determine whether the vehicle has paid the toll and whether it has completely passed through the toll station. For example, it can confirm whether the vehicle has abnormal behaviors such as reversing or staying. The second verification unit 108 can also perform data interaction with the first verification unit 107. If the verification result of the first verification unit 107 is that the vehicle is a violation vehicle, the second verification unit 108 will further identify the violation behavior of the vehicle. If the verification result of the first verification unit 107 is that the vehicle is a normal vehicle, the re-verification by the second verification unit 108 can ensure the accuracy of the verification result in case the first verification unit 107 malfunctions or makes a verification error.
[0076] Exemplarily, when the vehicle passes through the traffic restriction bar, the third sensing unit 109 detects the passing signal of the vehicle and sends it to the second verification unit 108. If the vehicle passes normally and leaves the toll station area, there will be no special reaction. However, if the vehicle reverses or stays for a long time after passing, the second verification unit 108 will identify the abnormality and notify the central control module 101 to take corresponding measures, such as issuing an alarm to prompt the staff to handle it, or controlling the driving motor 106 to lower the traffic restriction bar to prevent possible problems. For example, a certain vehicle suddenly reverses after passing, and the second verification unit 108 detects this abnormal behavior and promptly notifies the staff to intervene to ensure the normal order and safety of the toll station.
[0077] In this embodiment, by adding the linkage between the third sensing unit 109 and the second verification unit 108, the system can accurately identify the toll payment and passing status of the vehicle, timely identify abnormal behaviors such as reversing and staying, ensure the smoothness and safety of the toll collection process, and at the same time cooperate with the first verification unit 107 to enhance the verification accuracy, avoid misjudgment, and improve the management efficiency and service quality of the toll station.
[0078] As Figure 2 shown, in an embodiment of the present disclosure, an automatic traffic restriction bar lifting control system for a toll station further includes:
[0079] A camera module 110.
[0080] The camera module 110 includes a first camera unit and a second camera unit. Both the first camera unit and the second camera unit are connected to the central control module 101. The first camera unit is arranged in the area where the second sensing unit 105 is located, and the second camera unit is arranged in the area where the third sensing unit 109 is located.
[0081] The first camera unit is configured to collect image information of the area where the second sensing unit 105 is located.
[0082] The second camera unit is configured to collect image information of the area where the third sensing unit 109 is located.
[0083] In this embodiment, when the first verification unit 107 or the second verification unit 108 detects a violation of a vehicle, the first camera unit and the second camera unit may be activated to track and photograph the vehicle.
[0084] For example, the camera module 110 may be a high-definition camera with good image acquisition capability. The first camera unit and the second camera unit are connected to the central control module 101 by wire or wireless means to ensure stable transmission of image information.
[0085] In a toll station, when a vehicle enters the area where the second sensing unit 105 is located, if the first verification unit 107 detects that the vehicle has cut in line, or the vehicle has no ETC but uses the ETC express lane, it will notify the central control module 101 to activate the camera module 110. The first camera unit tracks and photographs the vehicle that cuts in line, records its violation process, and tracks the vehicle's license plate information. After the vehicle passes the restriction pole, if the second verification unit 108 finds that the vehicle has reversed or stayed in the area where the third sensing unit 109 is located, the second camera unit will also be activated to take pictures. These captured image information can be used as evidence for subsequent processing and punishment to maintain the normal order of the toll station.
[0086] In this embodiment, when a vehicle is detected to have violated a regulation, the first camera unit is activated to take pictures. At this time, the vehicle is close to the camera, and since the entire process occurs in a short time, it is difficult for the first camera unit to collect comprehensive vehicle information. At this time, the second camera unit is activated to take pictures from a farther position to capture the full picture of the vehicle and the surrounding environment, which is convenient for identifying the on-site situation.
[0087] This embodiment adds a camera module 110, which significantly improves the monitoring and evidence collection capabilities of illegal behaviors. When illegal behaviors are detected, the first and second camera units can respectively shoot at close range and long distance, comprehensively record the illegal process, ensure the accuracy and completeness of the image information, provide strong evidence for subsequent processing, and effectively maintain the order and safety of the toll station.
[0088] like Figure 2 As shown, in one embodiment of the present disclosure, a toll station automatic lifting control system further includes:
[0089] Vehicle monitoring module 111. The central control module 101 is connected to the vehicle monitoring module 111. The vehicle monitoring module 111 is configured to collect vehicle position information and vehicle speed information.
[0090] The central control module 101 is further configured to control the lifting speed of the limit rod according to the vehicle position information and the vehicle speed information.
[0091] In this embodiment, the vehicle monitoring module 111 collects the position information and speed information of the vehicle in real time and transmits this information to the central control module 101. The central control module 101 judges the distance between the vehicle and the traffic restriction bar and the driving speed of the vehicle according to the received vehicle position and speed information, so as to calculate an appropriate lifting speed of the traffic restriction bar. By controlling the lifting speed of the traffic restriction bar, it is possible to ensure that the vehicle passes through the toll station safely and smoothly, while improving the passing efficiency of the toll station.
[0092] Exemplarily, the vehicle monitoring module 111 may adopt devices such as sensors and radars to collect the vehicle position information and speed information. These devices communicate with the central control module 101 and transmit the data to the central control module 101 in real time. The central control module 101 analyzes and processes the vehicle position and speed information according to the preset algorithms and logics, calculates the lifting speed of the traffic restriction bar, and sends corresponding control instructions to the driving motor 106. Control the operating power, rotation speed and rotation direction of the driving motor 106 to control the lifting speed of the traffic restriction bar.
[0093] Exemplarily, when the vehicle approaches the toll station, the vehicle monitoring module 111 detects the position and speed of the vehicle. If the vehicle speed is relatively fast and the distance from the traffic restriction bar is relatively close, the central control module 101 will control the driving motor 106 to increase the lifting speed of the traffic restriction bar to ensure that the vehicle can pass in time and avoid collisions. For example, when a car drives towards the toll station at a relatively fast speed, the vehicle monitoring module 111 feeds back the vehicle information in real time. After judging according to this information, the central control module 101 quickly increases the lifting speed of the traffic restriction bar, enabling the car to pass smoothly. On the contrary, if the vehicle speed is relatively slow, the central control module 101 will appropriately slow down the lifting speed of the traffic restriction bar to ensure the smoothness of the operation.
[0094] In this embodiment, the vehicle monitoring module 111 is further configured to collect vehicle attribute information.
[0095] The central control module 101 is further configured to control the lifting height of the traffic restriction bar according to the vehicle attribute information. The vehicle attribute information includes vehicle shape data, such as vehicle height, length and width.
[0096] The central control module 101 controls the lifting height of the traffic restriction bar according to the vehicle attribute information, especially the vehicle height. For example, for a relatively high vehicle, the central control module 101 will correspondingly increase the lifting height of the traffic restriction bar to ensure that the vehicle can pass safely, while for a relatively low vehicle, the lifting height of the traffic restriction bar can be appropriately reduced to save the time of lifting and lowering the bar, reduce the vehicle waiting time, and improve the vehicle passing efficiency of the toll station.
[0097] Exemplarily, at a toll station, when a large truck enters, the vehicle monitoring module 111 collects that the height of the vehicle is greater than the first threshold, and the length and width are also large. After receiving this information, the central control module 101 controls the driving motor 106 to raise the traffic restriction bar to a relatively high height to ensure that the truck can pass smoothly without colliding with the traffic restriction bar. When a small car enters, due to its relatively low vehicle height, the central control module 101 will control the traffic restriction bar to be raised to a relatively low height, which can not only meet the passing requirements of the car but also improve the passing efficiency. Such a design can flexibly adjust the raising height of the traffic restriction bar according to the attributes of different vehicles to ensure the safety and smoothness of the toll station.
[0098] As Figure 2 shown, in an embodiment of the present disclosure, an automatic traffic restriction bar lifting control system for a toll station further includes:
[0099] A traffic restriction bar position monitoring module 112. The traffic restriction bar position monitoring module 112 is connected to the central control module 101.
[0100] The traffic restriction bar position monitoring module 112 includes a laser distance sensor. The laser distance sensor is arranged at the end of the traffic restriction bar and is configured to measure the distance between the end of the traffic restriction bar and the ground.
[0101] In this embodiment, the laser distance sensor in the traffic restriction bar position monitoring module 112 is arranged at the end of the traffic restriction bar. It emits laser to the ground and receives the reflected laser signal. By measuring the propagation time of the laser, the sensor can calculate the distance between the end of the traffic restriction bar and the ground and transmit this distance information to the central control module 101 in real time. The central control module 101 can accurately understand the position state of the traffic restriction bar according to the received distance information.
[0102] Exemplarily, in the actual scenario of the toll station, the central control module 101 can obtain the minimum lifting height of the traffic restriction bar to ensure the smooth passing of the vehicle by calculating the height information and position information of the vehicle. When the traffic restriction bar is lifted or lowered, the laser distance sensor will monitor the distance between the end of the traffic restriction bar and the ground in real time. When the height is reached, it will timely feedback to the central control module 101, and the central control module 101 controls the driving motor 106 to stop raising the traffic restriction bar. For example, during normal lifting of the traffic restriction bar, the sensor ensures that the traffic restriction bar is lifted to the specified height to ensure that the vehicle can pass smoothly. In this way, the traffic restriction bar position monitoring module 112 can effectively improve the safety and reliability of the automatic traffic restriction bar lifting control system for the toll station.
[0103] In the toll station automatic lifting control system of this embodiment, the laser distance sensor in the restricted line pole position monitoring module 112 is used to monitor the distance between the end of the restricted line pole and the ground in real time, ensuring that the restricted line pole can accurately reach the predetermined height when lifting or lowering, thereby improving the safety and reliability of the system and ensuring the smooth passage of vehicles. At the same time, according to different vehicle conditions, the lifting height of the restricted line pole can be flexibly controlled, which can improve the vehicle passing efficiency.
[0104] As Figure 2 shown, in an embodiment of the present disclosure, a toll station automatic lifting control system further includes:
[0105] A traffic flow monitoring module 113. The traffic flow monitoring module 113 is connected to the central control module 101.
[0106] The traffic flow monitoring module 113 is configured to monitor the traffic flow of the toll station lane. The central control module 101 is further configured to control the working states of the drive motor 106 and the restricted line pole position monitoring module 112 according to the traffic flow.
[0107] In this embodiment, the traffic flow monitoring module 113 includes: a road monitoring camera and an image recognition unit.
[0108] The image recognition unit is respectively connected to the road monitoring camera and the central control module 101.
[0109] The road monitoring camera is configured to collect traffic images of the toll station lane.
[0110] The image recognition unit is configured to calculate the traffic flow according to the traffic images of the toll station lane.
[0111] In this embodiment, when the traffic flow is small, the restricted line pole position monitoring module 112 remains closed. The central control module 101 does not calculate the lifting height of the restricted line pole. When the traffic flow is large, the central control module 101 activates the restricted line pole position monitoring module 112, and the central control module 101 controls the lifting height of the restricted line pole according to the vehicle information.
[0112] Exemplarily, when the traffic flow at the toll station is small, such as at night or during off-peak hours, the images collected by the road monitoring camera show few vehicles on the lane. The image recognition unit calculates that the traffic flow is small, and the central control module 101 then keeps the restricted line pole position monitoring module 112 in a closed state and does not calculate the lifting height of the restricted line pole. During peak hours, the traffic flow increases, the number of vehicles in the images collected by the camera increases, the image recognition unit calculates that the traffic flow is large, the central control module 101 activates the restricted line pole position monitoring module 112, and according to the attribute information of the vehicles, such as the heights of large trucks, buses, cars, etc., controls the restricted line pole to lift the corresponding height, enabling the vehicles to pass through the toll station smoothly while improving the passing efficiency.
[0113] As Figure 2 shown, in an embodiment of the present disclosure, an automatic toll gate lifting control system further includes:
[0114] A plurality of indicator lights 114 and an alarm 115.
[0115] The plurality of indicator lights 114 are arranged on the traffic restriction bar.
[0116] The plurality of indicator lights 114 and the alarm 115 are both connected to the central control module 101.
[0117] Exemplarily, the plurality of indicator lights 114 are arranged on the traffic restriction bar, and the alarm 115 is connected to the central control module 101. The central control module 101 sends control signals to the indicator lights and the alarm 115 according to the operating state of the automatic toll gate lifting control system. For example, when the vehicle verification is passed and the central control module 101 controls the driving motor 106 to lift the traffic restriction bar, it will simultaneously control the indicator lights to display green, indicating that passage is allowed. When the vehicle verification fails or a system fault occurs, the central control module 101 will control the indicator lights to display red and activate the alarm 115 to emit an alarm sound to remind the staff to handle it.
