For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] The existing height limit system usually uses a single height limit device to limit the height, which has certain limitations. For example, the traditional height limit device uses a steel frame directly fixed to the bridge head. This setting method uniformly limits the vehicles. Since fire trucks or special transport vehicles are relatively tall, these vehicles cannot pass in an emergency.

[0035] For another example, some existing height limiting devices use multiple height limiting structures fixed on the crossbeam. On the one hand, the height adjustment range of the height limiting structure is limited by the height of the crossbeam; on the other hand, the height limiting structure of each lane is adjusted without taking the width of the vehicle into consideration. If only the height of the height limiting structure of the lane where the vehicle is located is adjusted, the vehicle cannot pass normally and the height limiting structure is easily damaged.

[0036] Therefore, whether a unified height limit device is set up or a single height limit structure is set up in each lane, it is impossible to fully or partially limit the height according to the different conditions of the vehicles on the lane to adapt to the traffic needs of different vehicles.

[0037] Based on this, in a first aspect, a first embodiment of the present disclosure provides a height-limiting system for passing, Figure 1 It is a structural schematic diagram of a traffic height restriction system disclosed in Embodiment 1 of the present disclosure.

[0038] like Figure 1As shown, the height restriction system 100 includes a height restriction unit 110, a collection unit 120 and a control unit 130. The height restriction unit 110 may include a first height restriction unit 111 and a second height restriction unit 112. The collection unit 120 may include a first collection unit 121, a second collection unit 122 and a third collection unit 123.

[0039] The first height limiting unit 111 may include a height limiting column and a height limiting beam, and the height limiting beam is connected to the height limiting column through a first lifting mechanism, wherein the first lifting mechanism is used to adjust the height of the height limiting beam to limit the height of all lanes. The second height limiting unit 112 may be arranged on the height limiting beam, and include at least one height limiting display screen, each height limiting display screen corresponds to a lane, and the height limiting display screen is connected to the height limiting beam through a second lifting mechanism, wherein the second lifting mechanism is used to adjust the height of the height limiting display screen to limit the height of the lane corresponding to the height limiting display screen.

[0040] For example, Figure 2 As shown, the height limit unit may include a height limit column 1, a height limit beam 5 and a height limit display screen 7. The two ends of the height limit beam 5 are respectively connected to the height limit column 1 through a screw slider mechanism. By controlling the screw slider mechanism at both ends of the height limit beam 5, the height of the height limit beam can be adjusted to limit the height of all lanes. The height limit display screen 7 is arranged on the height limit beam 5, each height limit display screen 7 corresponds to a lane, and a protective cover 6 is also installed on each height limit display screen 7. The height limit display screen 7 is connected to the height limit beam 5 through a screw slider mechanism. By controlling the screw slider mechanism on the back of the height limit display screen, the height of the height limit display screen 7 can be adjusted to limit the height of the lane corresponding to the height limit display screen.

[0041] In addition, a mounting box 2 is provided on each height limiting column 1, and each mounting box can be used to install a solar panel 3 and an axial fan 4 for supplying power to the first height limiting unit and the second height limiting unit.

[0042] The acquisition unit 120 may be disposed at a preset distance from the height limiting unit 110 , and is used to acquire vehicle image data and send the vehicle image data to the control unit 130 , wherein the vehicle image data includes image data of a vehicle in each lane.

[0043] In some embodiments, the preset distance may be a first distance S1, a second distance S2, and a third distance S3. The first acquisition unit 121, the second acquisition unit 122, and the third acquisition unit 123 may be respectively located at a first distance S1, a second distance S2, and a third distance S3 from the height limiting unit, wherein the first distance is greater than the second distance and the second distance is greater than the third distance, that is, S1>S2>S3.

[0044] In some embodiments, each acquisition unit may include at least one camera mechanism, wherein the camera mechanism is used to acquire image data of vehicles in each lane. For example, the camera mechanism may be a camera, that is, at least one camera is provided at a preset distance to capture images of vehicles in each lane.

[0045] For example, Figure 3 As shown, height limit columns 1 are respectively arranged on both sides of the lane, height limit beams 5 span the lanes to limit the height of all lanes, height limit display screens 7 are arranged on the height limit beams to limit the height of a single lane, and cameras 10, 9 and 8 are respectively arranged at positions S1, S2 and S3 for capturing vehicle images.

[0046] The control unit 130 is used to receive vehicle image data, generate a height limit control instruction according to the vehicle image data, and send the height limit control instruction to the height limit unit to perform height limit for passage.

[0047] In some embodiments, the system may further include a power supply unit, the power supply unit including at least one solar panel and at least one axial wind turbine, Figure 2 As shown, the solar panel 3 and the axial fan 4 are fixed on the top of the height-limiting column 1 through the mounting box 2.

[0048] The height limit system provided in the embodiment of the present disclosure can generate height limit control instructions based on vehicle image data through the coordinated work of the height limit unit, the acquisition unit and the control unit, thereby achieving full or partial height limit for vehicles on the lane to meet the passage needs of different vehicles, thereby improving road use efficiency and safety.

[0049] Figure 4 FIG. 1 is a flow chart of a method for generating a height limit control instruction according to vehicle image data disclosed in the first embodiment of the present disclosure. In a feasible implementation manner, Figure 4 As shown, generating a height limit control instruction according to the vehicle image data and sending the height limit control instruction to the height limit unit to perform the height limit for passing may include steps S401 to S402.

[0050] Step S401: Determine the height, width and license plate number of the vehicle in each lane according to the vehicle image data.

[0051] Step S402: When the vehicles in at least one lane do not meet the height limit conditions, a height limit control instruction is generated according to whether the license plate number of the vehicles in each lane meets the passage conditions, and the height limit control instruction is sent to the first height limit unit or the second height limit unit to perform the height limit.

[0052] It should be noted that if the height of the vehicle is greater than the height limit threshold, it is considered that the vehicle does not meet the height limit conditions; if the height of the vehicle is less than or equal to the height limit threshold, it is considered that the vehicle meets the height limit conditions.

[0053] The height limit threshold is the initial height of the height limit display screen. It can be understood that the height limit beam is set across, that is, the height of the height limit beam can uniformly limit the maximum pass height of all lanes. In the initial state, the center position of the height limit display screen is set on the height limit beam. Since the height limit display screen itself has a certain height, the lower end of the height limit display screen can individually limit the minimum pass height of each lane. Since the height limit display screen is set on the height limit beam, it can be adjusted up and down relative to the height limit beam. Therefore, if the height of the vehicle is greater than the minimum pass height (generally, the height of the vehicle will not be greater than the maximum pass height), the height of the height limit display screen can be individually adjusted to make the minimum pass height greater than the height of the vehicle. Therefore, the height of the height limit display screen is used as the height limit threshold.

[0054] The disclosed embodiment pre-determines whether the vehicle height meets the height limit requirements and intelligently generates height limit control instructions, thereby achieving precise management of vehicle traffic, improving road traffic efficiency, ensuring driving safety, and at the same time adapting to the traffic needs of different vehicles and optimizing traffic flow.

[0055] Figure 5 1 is a flow chart of a method for generating a height limit control instruction according to whether the license plate number of the vehicle in each lane meets the traffic conditions disclosed in the first embodiment of the present disclosure. In a feasible implementation manner, Figure 5 As shown, the above step S402 may include steps S501 to S503.

[0056] It should be noted that if the vehicle's license plate number corresponds to a successful request for passage, the vehicle is considered to meet the passage conditions; if the vehicle's license plate number does not correspond to a successful request for passage, the vehicle is considered to not meet the passage conditions.

[0057] Step S501: If the vehicles in all lanes meet the traffic conditions, a first height limit control instruction is generated and sent to a first height limit unit.

[0058] The first height limit control instruction is used to control the first lifting mechanism to raise the height of the height limit beam to allow vehicles in all lanes to pass.

[0059] Step S502: If the vehicles in some lanes meet the traffic conditions, and the vehicles in each lane that meet the traffic conditions meet the width limit conditions, a second height limit control instruction is generated and sent to the second height limit unit.

[0060] The second height limit control instruction is used to control the second lifting mechanism to raise the height of the height limit display screen in the lane where the vehicles meeting the traffic conditions are located so as to allow vehicles in some lanes to pass.

[0061] Step S503: If the vehicles in some lanes meet the traffic conditions, and the vehicles in at least one lane that meets the traffic conditions do not meet the width limit conditions, a third height limit control instruction is generated and sent to the second height limit unit.

[0062] The third height limit control instruction is used to control the second lifting mechanism to raise the height of the height limit display screen in the lane and adjacent lane where vehicles that meet the traffic conditions and do not meet the height limit conditions are located, and to raise the height of the height limit display screen in the lane where vehicles that meet the traffic conditions and meet the width limit conditions are located to allow vehicles in some lanes to pass.

[0063] For example, suppose there are 4 lanes, and vehicles in 3 lanes do not meet the height limit conditions. If the vehicles in the 3 lanes meet the pass conditions, the height of the height limit beam is raised so that the height of the height limit display screen is greater than the maximum height of all vehicles to allow all vehicles to pass. If the vehicles in one lane meet the pass conditions, but the vehicles in the other two lanes do not meet the pass conditions, and the width of the vehicle is less than the lane width, the height limit display screen corresponding to the lane where the vehicle that meets the pass conditions is located is raised separately, so that the vehicle can pass.

[0064] The disclosed embodiment intelligently determines whether a vehicle meets the conditions for passage and width limitation, flexibly generates and sends corresponding height limit control instructions to the lifting mechanism, thereby realizing precise adjustment of the height of the lane height limit display screen to meet the passage requirements of vehicles in different lanes, optimizing traffic flow management, improving road use efficiency, and ensuring driving safety. Especially in a multi-lane environment, personalized height limit adjustment can be made according to actual conditions, so that vehicles that meet the conditions can pass smoothly, and vehicles that do not meet the conditions are effectively restricted, thereby realizing refined traffic control.

[0065] In the first aspect, based on the first embodiment, the second embodiment of the present disclosure provides a height-limiting system. Figure 6 It is a structural schematic diagram of a traffic height restriction system disclosed in Embodiment 2 of the present disclosure.

[0066] like Figure 6As shown, the height-limiting system 100 includes a height-limiting unit 110, a collection unit 120, and a control unit 130. The height-limiting unit 110 may include a first height-limiting unit 111 and a second height-limiting unit 112. The collection unit 120 may include a first collection unit 121, a second collection unit 122, and a third collection unit 123. An early warning unit 140 may also be included, and the early warning unit 140 may include a first early warning unit 141, a second early warning unit 142, and a third early warning unit 143.

[0067] In some embodiments, the preset distance may be a first distance S1, a second distance S2, and a third distance S3. The first warning unit 141, the second warning unit 142, and the third warning unit 143 may be respectively arranged at the first distance S1, the second distance S2, and the third distance S3 of the height limiting unit, wherein the first distance is greater than the second distance and the second distance is greater than the third distance, that is, S1>S2>S3.

[0068] In some embodiments, the first warning unit 141 includes at least one sound broadcasting mechanism, and the second warning unit 142 and the third warning unit 143 respectively include at least one sound broadcasting mechanism and at least one road deceleration mechanism, and each road deceleration mechanism corresponds to a lane. The sound broadcasting mechanism is used to broadcast the warning information of the vehicle, and the road deceleration mechanism is used to reduce the vehicle speed.

[0069] In a feasible implementation manner, the control unit is further used to generate a warning control instruction based on the vehicle image data, and send the warning control instruction to the warning unit and / or the height limit display screen for warning prompts.

[0070] The embodiment of the present disclosure adds an early warning unit, which effectively improves driving safety and traffic management efficiency.

[0071] Figure 7 FIG. 1 is a flow chart of a method for generating early warning control instructions according to vehicle image data disclosed in the first embodiment of the present disclosure. Figure 7 As shown, generating a warning control instruction according to the vehicle image data, and sending the warning control instruction to the warning unit and / or the height limit display screen for warning prompting may include steps S701 to S702.

[0072] Step S701: Determine the height, license plate number and speed of the vehicle in each lane based on the vehicle image data.

[0073] Step S702: When the vehicles in at least one lane do not meet the height limit conditions and the traffic conditions, a warning control instruction is generated according to the current position of the vehicles in each lane and the speed of the vehicles, and the warning control instruction is sent to the warning unit and / or the height limit display screen for warning prompts.

[0074] If the height of the vehicle is greater than the height limit threshold and the vehicle's license plate number has no corresponding successful passage request or the vehicle's license plate number has a failed passage request, the vehicle is considered to meet neither the height limit condition nor the passage condition.

[0075] The disclosed embodiment analyzes vehicle image data to accurately determine the height, license plate number and speed of the vehicle, and when it detects that the vehicle does not meet the height limit or passage conditions, it intelligently generates early warning control instructions based on the vehicle's position and speed, and promptly sends early warning prompts to the early warning unit and height limit display screen, effectively alerting the driver and guiding him to take corresponding measures, thereby improving road safety, reducing illegal passage incidents, and ensuring smooth traffic and vehicle safety.

[0076] Figure 8 is a flow chart of a method for generating a warning control instruction according to the current position and speed of a vehicle in each lane disclosed in the first embodiment of the present disclosure. In a feasible implementation manner, Figure 8 As shown, the above step S702 may include steps S801 to S803.

[0077] Step S801: If the vehicle is at a first distance and the vehicle speed is greater than a first speed threshold, a first warning control instruction is generated and sent to a first warning unit and a height limit display screen.

[0078] The first early warning control instruction is used to activate a sound broadcasting mechanism located at a first distance from the height limit display screen in the lane where the vehicle is located.

[0079] Step S802: If the vehicle is at a second distance and the vehicle speed is greater than a second speed threshold, a second warning control instruction is generated and sent to a second warning unit.

[0080] The second early warning control instruction is used to activate the sound broadcasting mechanism located at the second distance and the road deceleration mechanism of the lane where the vehicle is located.

[0081] Step S803: If the vehicle is at a third distance and the vehicle speed is greater than a third speed threshold, a third warning control instruction is generated and sent to a third warning unit.

[0082] The third warning control instruction is used to activate the sound broadcasting mechanism located at the third distance and the road deceleration mechanism of the lane where the vehicle is located.

[0083] In the embodiment of the present disclosure, the first speed threshold is greater than the second speed threshold, and the second speed threshold is greater than the third speed threshold.

[0084] For example, when the vehicle does not meet the height limit conditions or the traffic conditions, if the vehicle is in the S1 position and the speed is greater than 60km / h, the vehicle will be warned by sound and electronic display screen; if the vehicle is in the S2 position and the speed is greater than 45km / h, the vehicle will be warned by sound and electronic display screen, and the deceleration device will be used to decelerate the vehicle once; when the vehicle is in the S1 position and the speed is greater than 25km / h, the vehicle will be warned by sound and electronic display screen, and the deceleration device will be used to decelerate the vehicle for a second time, and the traffic system will be reported for alarm processing.

[0085] The disclosed embodiment sets speed thresholds at different preset distances and intelligently generates corresponding warning control instructions according to the actual speed of the vehicle, thereby providing graded warning prompts for vehicles that do not meet the height limit conditions and the traffic conditions.
