[0036] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the implementation manners and the accompanying drawings. Herein, the illustrative implementation manners of the present utility model and their descriptions are used to explain the present utility model, but do not limit the present utility model.

[0037] Herein, it should also be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.

[0039] Herein, it should also be noted that if not otherwise specified, the term "connection" in this article can not only refer to direct connection, but also represent indirect connection with an intermediate.

[0040] In the following, embodiments of the present utility model will be described with reference to the drawings. In the drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0041] To solve the technical problem in the prior art that it is difficult to monitor the impact on the height-limiting gantry and trace the vehicle causing the accident, the present utility model proposes a monitoring device for monitoring the impact on the height-limiting gantry and a height-limiting gantry safety monitoring system, which can monitor in real time whether the height-limiting gantry is impacted, capture photos of the vehicle causing the accident, and hold the vehicle causing the accident accountable based on information such as the license plate of the vehicle causing the accident and the damage degree of the height-limiting gantry.

[0042] On the one hand, an embodiment of the present utility model provides a monitoring device for monitoring the impact on the height-limiting gantry. Referring to Figure 1 the structural schematic diagram of the monitoring device, the height-limiting gantry includes a column 1 and a cross beam 2. The monitoring device includes a vehicle information acquisition component, an impact detection component, and an information transmission component. Among them, the vehicle information acquisition component includes a first image collector 4. The first image collector 4 is installed on the height-limiting gantry or on a support component 9 located in front of the height-limiting gantry. The first image collector 4 is used to collect images of vehicles passing by the height-limiting gantry. The impact detection component is installed on the cross beam 2 or the column 1 of the height-limiting gantry. The impact detection component includes a micro-core pile 5. The micro-core pile 5 includes an inclination sensor 51, an acceleration sensor 52, and a vibration sensor 53, which are respectively used to monitor the inclination information, acceleration information, and vibration information of the height-limiting gantry. The information transmission component is communicatively connected to the vehicle information acquisition component and the impact detection component, and is used to transmit the vehicle information and the inclination information, acceleration information, and vibration information of the height-limiting gantry to a remote server.

[0043] In this embodiment, the first image collector 4 can be arranged on the height-limiting gantry or the support component, and both can collect images of vehicles.

[0044] In a specific implementation manner, when the first image collector 4 is installed on the height-limiting gantry, the collision position between the vehicle and the height-limiting gantry can be accurately captured. However, after the height-limiting gantry is impacted or even knocked down by the vehicle, it is easy to cause the reliability of the first image collector to decrease, fail, or be damaged. Moreover, generally, the height-limiting gantry is a beam structure and does not have a structure for installing other components, so the installation of the first image collector requires targeted design.

[0045] In another specific embodiment, the first image collector 4 is installed on the support assembly 9. The first image collector 4 will not shake or be damaged due to the impact of the overhead guard, ensuring the safety of the first image collector 4, especially suitable for serious accidents after the overhead guard is knocked down. When the overhead guard is knocked down or a serious accident occurs, the safety of the first image collector is guaranteed, which is crucial for image recording and evidence collection at the accident scene. This setting method can ensure that the image collector can continue to operate, providing necessary support for accident investigation and liability determination. The first image collector 4 or other information collection components are installed on the support assembly 9, and the position and angle can also be adjusted more flexibly to maximize the effect of image collection. The first image collector or other components on the support assembly can be assembled, accessed, and maintained more easily. In other embodiments, the first image collector 4 can also be installed on another support assembly located behind the overhead guard, where the "rear" mentioned here refers to the vehicle departure direction, and the "front" refers to the vehicle approaching direction.

[0046] In this embodiment, when the overhead guard is impacted, the overhead guard itself will generate changes in inclination angle, acceleration, or vibration. The inclination sensor 51, acceleration sensor 52, and vibration sensor 53 in the micro-pile 5 can collect the change information and convert it into electrical signals, which are transmitted to the remote server through the information transmission component. The remote server can control the first image collector 4 to capture the vehicle involved in the accident, obtaining information such as the vehicle license plate, facilitating the supervision personnel to trace the vehicle. Alternatively, the first image collector 4 records the vehicles passing through the overhead guard in real time. When the impact occurs, the remote server retrieves the video information before and after the impact time point for the investigation by the supervision personnel. This monitoring device can obtain the information that the overhead guard is impacted in a timely manner and record the information of the vehicle involved in the accident, facilitating the supervision personnel to trace.

[0047] The micro-pile in this embodiment is a professional, integrated, and intelligent dynamics monitor. It can utilize the sensitivity and difference of different static-dynamic indexes in different instability evolution stages to realize the integration of the health state diagnosis of the monitored object and the early warning of instability. The built-in inclination sensor, acceleration sensor, and vibration sensor in the micro-pile can real-time monitor the inclination angle, acceleration change, and vibration condition of the overhead guard. This high-sensitivity monitoring ability enables the micro-pile to quickly and accurately sense whether the overhead guard has been impacted or affected by other external forces. Since the sensors in the micro-pile can collect data in real-time and transmit it to the remote server through the information transmission component, the real-time monitoring of the state of the overhead guard can be achieved. The micro-pile integrates an inclination sensor, an acceleration sensor, and a vibration sensor. Using multi-sensor fusion technology can improve the accuracy and reliability of the data. The data interaction and complementarity between different sensors enable the micro-pile to more comprehensively evaluate the state of the overhead guard, including but not limited to whether an impact has occurred and the specific situation of the impact. The micro-pile can be designed as a low-power device, which can operate stably for a long time without the need to frequently replace the battery or perform maintenance. This low-power design is crucial for long-term monitoring and real-time transmission, especially in the case where the device needs to be kept online and running. The micro-pile can be relatively easily installed on the crossbeam or column of the overhead guard without the need for large-scale modification of the overhead guard structure. This deployment flexibility makes the micro-pile applicable to various types and shapes of overhead guards, thereby improving the application scope and coverage rate of the monitoring system.

[0048] In some embodiments, the monitoring device further includes a support assembly 9. Refer to Figure 2 the structural schematic diagram of the support assembly. The support assembly 9 is located above or on one side of the road where the overhead guard is located. The support assembly 9 is used to install the first image collector 4. For example, the support assembly 9 can be set 30 - 50 meters in front of the road where the overhead guard is located. The support assembly 9 will not be impacted by over-height vehicles. Multiple first image collectors 4 can be set on the support assembly 9, respectively aligned with the overhead guard, the vehicle head, and the vehicle tail, and can take multi-angle photos of the overhead guard and the vehicle, facilitating the comprehensive collection of vehicle information and the photographing of the damaged condition of the overhead guard.

[0049] In some embodiments, the support assembly 9 includes any one of a vertical pole, a gantry, and a triangular bracket.

[0050] In some embodiments, the monitoring device further includes a vehicle height monitoring component. The vehicle height monitoring component is set on the support assembly 9. The vehicle height monitoring component includes any one of a first optoelectronic module 10, a second optoelectronic module 11, an acoustic ranging module 12, and a second image collector 13. The vehicle height monitoring component can monitor the height of the vehicle, obtain the vehicle height information, and different sensor modules can be used to monitor the vehicle height information.

[0051] Reference Figure 3 Schematic diagram of the structure of the first optoelectronic module in an embodiment. When the vehicle height monitoring component includes the first optoelectronic module 10, the first optoelectronic module 10 is arranged on the support component 9. The support component 9 is located on one side of the road where the overhead clearance gate is located. The installation height of the first optoelectronic module 10 is the same as the height of the crossbeam 2 of the overhead clearance gate. The first optoelectronic module 10 is used to horizontally transmit and receive the first optoelectronic signal to detect over-height vehicles. The direction of the first optoelectronic signal is configured to be parallel or inclined to the length direction of the overhead clearance gate.

[0052] The first optoelectronic module 10 can select a pair of optoelectronic sensors, which include an optoelectronic signal transmitter and an optoelectronic signal receiver.

[0053] In a specific embodiment, the two are symmetrically arranged horizontally on both sides of the road. The optoelectronic signal transmitter transmits the optoelectronic signal in real time, and the optoelectronic signal receiver receives the optoelectronic signal in real time. When the first optoelectronic signal is blocked, if the optoelectronic signal receiver cannot receive the signal, it is determined that the vehicle is over-height. This setting method is simple and reliable. The first optoelectronic signal emitted by the optoelectronic signal transmitter is in a horizontal form, and the height of the first optoelectronic signal is the same as the height restricted by the overhead clearance gate. When an over-height vehicle passes through the first optoelectronic signal, the first optoelectronic signal is blocked so that the optoelectronic signal receiver cannot receive it, and thus it can be judged that the vehicle exceeds the restricted height.

[0054] In another specific embodiment, the optoelectronic signal transmitter and the optoelectronic signal receiver are arranged on the same side of the road. When the signal emitted by the optoelectronic signal transmitter touches the top of the over-height vehicle, it is reflected and collected by the optoelectronic signal receiver. When the optoelectronic signal receiver collects the first optoelectronic signal, it is determined that the vehicle is over-height. In this way, the optoelectronic signal receiver does not need to receive the signal in real time, and the power consumption is low.

[0055] Reference Figure 4 Schematic diagram of the structure of the second optoelectronic module and the acoustic ranging module. When the vehicle height monitoring component includes the second optoelectronic module 11, the second optoelectronic module 11 is arranged on the support component 9. The support component 9 is located above the road where the overhead clearance gate is located. The installation height of the second optoelectronic module 11 is higher than the height of the crossbeam 2 of the overhead clearance gate. The second optoelectronic module 11 is used to vertically transmit and receive optoelectronic signals to detect the distance between the top of the vehicle passing through the support component 9 and the support component 9, so as to obtain the height information of the vehicle; the second optoelectronic module 11 can select a lidar system. The second optoelectronic module 11 emits a second optoelectronic signal. The second optoelectronic signal is reflected to the optoelectronic signal receiver after passing through the top of the vehicle, so as to obtain the distance between the top of the vehicle and the support component 9. Subtracting the distance between the top of the vehicle and the support component 9 from the height of the second optoelectronic module 11 is the height of the vehicle.

[0056] Reference Figure 4Schematic diagram of the structure of the second optoelectronic module and the acoustic ranging module. When the vehicle height monitoring component includes the acoustic ranging module 12, the acoustic ranging module 12 is arranged on the support component 9, and the support component 9 is located on one side of the road where the overhead clearance gate is located. The installation height of the acoustic ranging module 12 is the same as the height of the crossbeam 2 of the overhead clearance gate. The acoustic ranging module 12 is used to horizontally transmit and receive acoustic signals to detect over-height vehicles. The direction of the acoustic signal is configured to be parallel or inclined to the length direction of the overhead clearance gate; the acoustic ranging module 12 can emit horizontal acoustic signals. When the acoustic signal is blocked, it can be determined that the height of the vehicle exceeds the height of the overhead clearance gate.

[0057] Similarly, when the vehicle height monitoring component includes the acoustic ranging module 12, the support component 9 is located above the road where the overhead clearance gate is located. The installation height of the acoustic ranging module 12 is higher than the height of the crossbeam 2 of the overhead clearance gate. The acoustic ranging module 12 is used to vertically transmit and receive acoustic signals to detect the distance between the top of the vehicle passing through the support component 9 and the support component 9, so as to obtain the height information of the vehicle; the acoustic ranging module 12 emits an acoustic signal. After the acoustic signal hits the top of the vehicle and rebounds, the acoustic receiving device can calculate the distance between the vehicle roof and the acoustic ranging module 12 after receiving the acoustic signal. Then, subtracting the distance between the vehicle roof and the acoustic ranging module 12 from the height of the acoustic ranging module 12 is the vehicle height.

[0058] Refer to Figure 5 Schematic diagram of the structure of the second image collector. When the vehicle height monitoring component includes the second image collector 13, the second image collector 13 is arranged on the support component 9, and the support component 9 is located on one side of the road where the overhead clearance gate is located. The second image collector 13 is used to collect vehicle images passing through the support component 9, so as to obtain the height information of the vehicle. The second image collector 13 can perform visual recognition on the vehicle and directly calculate the height of the vehicle through computer algorithms, which is very convenient.

[0059] In some embodiments, the monitoring device further includes a risk warning component. The risk warning component is arranged on the overhead clearance gate and is used to prompt the vehicle driver when the vehicle height monitoring component detects that the vehicle is over-height. When the vehicle height monitored by the vehicle height monitoring component is less than the height of the overhead clearance gate, the risk warning component does not act. When the vehicle height monitored by the vehicle height monitoring component is greater than or equal to the height of the overhead clearance gate, the risk warning component acts to prompt the vehicle driver of the over-height information, so that the driver can change lanes or stop to prevent the over-height vehicle from hitting the overhead clearance gate.

[0060] In some embodiments, the risk warning component includes any one or more of a display screen 14, a warning light 15, and an alarm 16 arranged on the height limit frame. The display screen 14 can display text information of the vehicle and text information of the vehicle overheight warning to remind the driver, the warning light 15 can be in a flashing form to attract the driver's attention and let the driver observe the content on the display screen 14, and the alarm 16 can issue a voice or warning sound alarm to remind the driver that the vehicle is overheight.

[0061] In some embodiments, a third image collector 18 is provided on the support assembly 9, and the third image collector 18 is arranged toward the height limit frame, and is used to collect image information of the height limit frame after being hit and image information of the vehicle causing the accident. The third image collector 18 can collect images of the height limit frame in real time, monitor whether a collision occurs and the severity level of the collision, and send the damaged image of the height limit frame to the remote server for easy viewing by monitoring personnel. It can also take a photo of the license plate at the rear of the vehicle, and after sending it to the remote server, use image recognition technology or manually extract the license plate number of the vehicle causing the accident and evaluate the damage level of the height limit frame, so as to facilitate tracing the vehicle causing the accident.

[0062] In some embodiments, a fill light 17 is provided on the height limit frame or the support assembly 9, and the fill light 17 is used to illuminate vehicles passing through the height limit frame when the lighting conditions are insufficient, such as at night, on snowy days, or on foggy days. A plurality of fill lights 17 can be arranged side by side, mainly used to illuminate the vehicle license plate area, so that the first image collector 4 can take pictures.

[0063] Another aspect of the utility model embodiment provides a height-limited frame safety monitoring system, referring to Figure 7 The system diagram of the height limit frame safety monitoring system includes a monitoring device for monitoring the impact of the height limit frame, and also includes a remote server, an alarm device and a display device; the remote server is communicatively connected to the alarm device and the display device respectively, the remote server is used to receive the inclination information, acceleration information and vibration information of the height limit frame, the remote server is used to receive the vehicle image information collected by the first image collector 4, the remote server is used to send an alarm signal to the alarm device, and the remote server is used to send the vehicle image information to the display device.

[0064] In this embodiment, the micro-core pile 5 collects information about the height limit frame being hit, and sends the information to the remote server through the information transmission component. The remote server controls the first image collector 4 to capture the image of the vehicle involved in the accident. The first image collector 4 sends the image of the vehicle involved in the accident to the remote server. The remote server displays the image of the vehicle involved in the accident through the display device, and at the same time sends an alarm through the alarm device to alert the supervisor.

[0065] In some embodiments, the information transmission component includes a switch 7 , and the switch 7 is used for communication between the remote server and the first image collector 4 and the micro-core pile 5 .
