Description

Technical Field

[0001] The present invention belongs to but is not limited to the technical field of height restrictions, and in particular relates to a device and method for preventing a car from colliding with a height-restricted object. Background Art

[0002] During driving, cars often need to pass through facilities such as overpasses, tunnels or height limit poles. However, due to driver fatigue or negligence, and the vehicle height exceeds the limit, accidents are prone to occur, especially for trucks whose vehicle height is not fixed as the load changes.

[0003] Existing technologies often adopt the following technical means:

[0004] 1.CN12030813B: A collision-proof height-limiting pole

[0005] The invention discloses an anti-collision height limit pole, comprising: a table, a height limit pole, an overheight detection device and a deceleration braking device; the overheight detection device, an LED display screen and an alarm are arranged on the top of the height limit pole; when the overheight detection device detects that a vehicle is overheight, the LED display screen displays overheight reminder subtitles, and the alarm emits an overheight warning prompt sound, so as to remind the driver to decelerate and brake in time to avoid collision accidents; when it is detected that an overheight vehicle is about to hit the height limit pole due to untimely braking, a deceleration braking signal is immediately sent to a control device of the deceleration braking device, and the control device automatically hooks the hook of the brake hook to the front axle beam of the chassis of the automobile, and the automobile drives the hook forward under the action of inertia force, and the buffer brake performs buffer braking on the hook through a brake pull rope, so that the automobile is decelerated and buffer braked, so as to avoid physical harm to the driver of the automobile due to sudden braking.

[0006] 2. CN106251632A: A vehicle height detection and overheight alarm device and method

[0007] The present invention discloses a vehicle height detection and overheight alarm device and method. The device comprises a bracket, a power module, a main control module, a detection module, a trigger module and a display alarm module, wherein the trigger module, the detection module, the main control module and the display alarm module are connected in sequence, wherein the bracket provides an installation platform for the power module, the main control module and the detection module. The method is as follows: when a vehicle approaches the device, the trigger module triggers the device to work; when the vehicle passes through the device, the main control module obtains the vehicle height value of the vehicle by fusing the measurement values ​​returned by multiple laser ranging modules and performs the first vehicle overheight detection; after the vehicle passes through the device, the main control module performs a second overheight detection on the vehicle according to the switch signal of the photoelectric switch sensor, and transmits the vehicle height value and the two overheight detection results to the display alarm module. The present invention can realize non-contact measurement of vehicle height, with high accuracy, low cost, sensitive response and good real-time performance.

[0008] 3. Planar ultra-high laser radar technology

[0009] With the increasing busyness of transportation, the safety issues of railway-spanning public overpasses and height-limited protective frames have become increasingly prominent. In order to ensure the safe passage of bridges and roads and prevent safety accidents caused by collisions with super-high vehicles, the plane super-high laser radar technology plays an important role in the collision alarm system. The plane super-high laser radar uses laser ranging technology to measure the distance between the target and the radar by emitting a laser beam and receiving its reflected signal. At the same time, combined with the radar's rotation scanning function, it can achieve all-round monitoring of the surrounding environment. When an ultra-high object is detected approaching, the radar will immediately send out an alarm signal so that timely countermeasures can be taken.

[0010] 4. CN109143262A: Automatic control device and control method for unmanned vehicle

[0011] The present invention discloses an automatic control device for an unmanned vehicle, comprising: a vehicle speed sensor, an acceleration sensor, a vehicle-mounted laser radar, an embedded controller, a brake device and a steering gear. The embedded controller processes the data collected by the vehicle-mounted laser radar and calculates the steering amount of the steering gear. The brake device and the steering gear use a pull line to control the brake pedal. The information collected by the vehicle-mounted laser radar is the displacement, relative speed and relative acceleration of the vehicle and objects within a fixed range around the unmanned vehicle. It is suitable for vehicles with higher speeds, and can detect whether the vehicle will encounter surrounding objects within a certain range, and then use the embedded controller to process data to control the brake device to brake, thereby reducing the safety problems caused by unmanned vehicles when facing complex road conditions in reality.

[0012] Although there are many solutions to the problem of collision between cars and height-restricted objects in the existing technology, there are still the following main disadvantages:

[0013] Lack of targeting:

[0014] Concentration on height limit poles: The aforementioned CN12030813B, CN106251632A and planar ultra-high laser radar technologies all focus on the detection and alarm of height limit poles. Although they are effective in specific scenarios, these technologies cannot work in the absence of height limit poles, such as encountering temporary height limit objects or bridges during driving.

[0015] Complexity and cost:

[0016] The equipment is complex and expensive: For example, the integration of multiple laser ranging modules and complex photoelectric switch sensors involved in CN106251632A increases the complexity and cost of the equipment, and is difficult to install and maintain.

[0017] The threshold of driverless technology: CN109143262A is an automatic control device for driverless cars. Although the technology is advanced, its application scope is limited to driverless cars and cannot solve the height limit problem of traditional driving vehicles. Moreover, driverless technology has not yet been fully popularized, and the height limit problem of a large number of traditional vehicles needs to be solved before it can be popularized.

[0018] Lack of real-time performance and sensitivity:

[0019] Reaction lag: Some technologies, such as the mechanical brake device of CN12030813B, need to detect that the vehicle is about to hit the height limit pole before controlling the brake hook. There is a problem of reaction lag, which may easily lead to failure to provide timely warning and the risk of collision.

[0020] Limitations of non-contact measurement: Although planar ultra-high laser radar can perform non-contact measurement, its accuracy and stability are affected under complex road conditions and environmental changes.

[0021] Scope of application:

[0022] Dependence on autonomous driving: The solution of CN109143262A relies on autonomous driving technology, which is of no help to traditional cars that are still driven by humans. At present, the vast majority of vehicles are still traditional cars, so a universal solution is needed. Summary of the invention

[0048] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0049] First, for traditional vehicles:

[0050] Strong universality: The invention is specially designed for traditional driving cars and is applicable to most existing vehicles, not just driverless cars. Therefore, it can be widely used in traditional vehicles and drivers to solve the ubiquitous height restriction collision problem.

[0051] Easy installation and low transformation cost:

This technological innovation enables the system to accurately calculate the maximum pass height and compare it with the height of the car, so as to intelligently determine whether there is a collision risk.

[0067] Finally, the present invention wirelessly connects the mobile phone APP to the monitoring device, realizing the real-time sending and receiving of warning information. Once the risk of collision is determined, the driver can immediately receive the warning information and take corresponding safety measures. This technological advancement not only improves driving safety, but also effectively avoids vehicle damage and traffic accidents caused by collision with height-limited objects.

[0068] In summary, the technical solution of the present invention solves the problem of insufficient early warning of the risk of collision between a car and a height-restricted object in the prior art, and has achieved significant technical progress, including comprehensive perception and real-time acquisition of key information, accurate calculation of the maximum passing height and car height, and real-time sending and receiving of warning information.

[0073] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0074] like Figure 1 As shown, an embodiment of the present invention provides a device for preventing a car from colliding with a height-limited object, the device comprising: a monitoring device 1 and a mobile phone APP 2;

[0075] The monitoring device 1 is installed horizontally on the roof;

[0076] The mobile phone APP2 is installed on the driver's mobile phone, and a wireless connection (Bluetooth, Zigbee, WiFi, etc.) is established with the monitoring device through the APP.

[0077] Furthermore, the monitoring device 1 comprises the following components:

[0078] Two cameras 3: a front binocular camera, facing forward, used to observe roads, height-restricted objects, height-restricted signs, etc.; a rear monocular camera, facing upward and backward, used to observe the outline of the car;

[0079] Video analysis alarm unit 4: For the video stream of the front camera, the image processing and analysis algorithm is used to analyze the content of the height limit sign and the distance between the height limit object and the road surface, and the maximum passing height is obtained in combination with the height of the monitoring device (set by mobile phone APP); for the rear camera, the outline of the car is analyzed, and the height of the car is calculated in combination with the height of the monitoring device (set by mobile phone APP); the maximum passing height and the height of the car are used to determine whether there is a risk of collision; if it is determined that there is a risk of collision, the monitoring device will send an alarm message to the driver's mobile phone through the mobile phone APP to remind the driver to take corresponding safety measures.

Combined with the height information set by the monitoring device in the mobile phone APP, the system can accurately calculate the maximum pass height of the current road.

[0083] Furthermore, the video analysis and warning unit also conducts a detailed analysis of the car's outline image captured by the rear camera. By combining it with the height information of the monitoring device, the system can accurately calculate the actual height of the car. This data is crucial for subsequent judgment of whether there is a risk of collision.

[0084] Finally, the system intelligently determines whether the car faces a collision risk by comparing the maximum pass height with the car height. Once a risk is determined, the monitoring device will immediately send an alarm message to the driver's mobile phone through the mobile phone APP. In this way, the driver can receive a timely reminder and take corresponding safety measures to effectively avoid collisions with height-restricted objects.

[0090] (1) The binocular camera system imitates the working principle of human eyes, captures two perspective images of the same scene, and uses the parallax effect to calculate the distance of objects;

[0091] (2) Apply deep learning models (such as YOLO, SSD, etc.) to perform object detection on the captured images;

[0092] (3) The distance between the height-restricted object and the road surface is estimated by combining the known camera installation height and the position of the object in the image with geometric calculations (such as triangulation).

[0093] Furthermore, the mobile phone APP can set the installation height of the monitoring device.
