Detailed Description

Technical solutions in embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present disclosure without making any creative effort belong to the protection scope of the present disclosure.

Referring to fig. 1 to 3 together, an embodiment of the present disclosure provides a road safety monitoring device, which includes a detecting element 31, a control element 32, and a display element 35.

The detecting element 31 is arranged above the pedestrian crossing 13, the upper part refers to a position on the ground side back to the geocentric, and the specific position of the detecting element 31 above the pedestrian crossing 13 is not limited. The detecting member 31 may be supported by any supportable structure, and is not limited in particular. The height of the detecting member 31 relative to the ground may not be limited.

The display piece 35 is used for being arranged beside the roadway 11, the roadway 11 is used for the automobile 40 to run, the area beside the roadway 11 is an area which is located near the outside of the roadway 11 (for example, within 3m from the edge of the roadway 11), the display piece 35 is arranged beside the roadway 11, the normal running of the automobile 40 is not influenced, the distance from the roadway 11 is short, and the specific distance can be not limited, so that the driver can see the automobile 40 obviously when driving.

In the driving direction of the motor vehicle 40, the display element 35 and the detection element 31 are arranged in succession, the display element 35 having a first spacing distance S1 from the crosswalk 13. When the vehicle 40 travels from a distance toward the crosswalk 13, the vehicle 40 will travel to the vicinity of the display member 35 and then to the crosswalk 13, and the driver will see the display member 35 first. As shown in fig. 2, the first spacing distance S1 between the display 35 and the crosswalk 13 may be set as required, for example, the first spacing distance S1 may be 40m, 50m, 80m, 100m, and the like, and may not be limited specifically.

The control member 32 is electrically connected to the detecting member 31, and the control member 32 is also electrically connected to the display member 35. The control element 32 may be a local computer, a cloud server, or other types of devices, and the internal components of the control element 32 may include a processor, a memory, a communication interface, and the like, which are not limited specifically, and the control element 32 may be provided with a required circuit, such as an amplifying circuit, a filtering circuit, and the like, which are not limited specifically. The electrical connection between the control member 32 and the detecting member 31 and the display member 35 can be a wired connection or a wireless connection, and is not limited in particular.

In a preset time period at night, the detection piece 31 acquires the image information of the pedestrian crossing 13, and the control piece 32 determines whether the pedestrian crossing 13 is occupied or not according to the image information of the pedestrian crossing 13 provided by the detection piece 31.

Specifically, the preset time period at night can be set as required, taking longitude and latitude of the beijing, and the season as summer, for example, and the preset time period can be 20 at night of the beijing: 00-morning 5: 00. it should be understood that the preset time period may be set according to season, longitude and latitude of the place, time zone, etc. In general, the preset time period substantially covers a time period in which natural light is insufficient from the time when the sun falls on the first day to the time when the sun rises on the second day, and it is difficult for the driver to clearly see the situation at the crosswalk 13 in the distance.

Optionally, the preset time period at night can be adjusted through the control element 32, and the control element 32 can adjust the preset time period according to factors such as seasons and the like, so that the automation level of the device disclosed by the disclosure is improved. Optionally, the device of the present disclosure may further include an ambient light sensor electrically connected to the control element 32, where the ambient light sensor senses brightness information of ambient light, and the control element 32 may adjust the preset time period according to the brightness information of the ambient light, for example, when the brightness of the ambient light is lower than the preset brightness, the device of the present disclosure is activated, and when the brightness of the ambient light is higher than the preset brightness, the device of the present disclosure is not activated. Alternatively, the preset time period may be manually adjusted at night.

The detection member 31 acquires image information at the crosswalk 13, which may be a picture or a video, in real time, so as to analyze the real-time pedestrian situation at the crosswalk 13.

After the image information is acquired by the detecting element 31, the image information is transmitted to the control element 32 in a wired or wireless manner, and the control element 32 performs calculation analysis on the image information to obtain the judgment of whether a person is in the crosswalk 13. The control 32 may analyze the image information by a computer program including an algorithm, and the computer program of the algorithm may be implemented by any available technology, and the disclosure is not particularly limited, for example, the image information may be analyzed by a neural network algorithm, and the conclusion of whether a person is present at the crosswalk 13 may be accurately determined.

When the control 32 determines that there is a person in the crosswalk 13, the control 32 controls the display 35 to display a warning image.

Optionally, the display element 35 is preset with a reminding image, the control element 32 determines that there is a person in the pedestrian crossing 13, transmits a control signal to the display element 35 in a wired or wireless manner, and the display element 35 displays the reminding image.

Optionally, the display element 35 has no preset image, and the control element 32 may send a video signal of the reminding image to the display element 35 for displaying.

The reminding image can be a picture, a character, a video, an animation and the like, and is not limited specifically. As shown in fig. 4, in an example, the reminder image may be specifically in the word "person", and other examples of the reminder image are not illustrated. It should be appreciated that the reminder image should be eye-catching and distinct, and have a strong visual stimulus to the driver of the automobile 40, ensuring that the driver of the automobile 40 can see it so that the driver can take timely action to avoid an accident. The reminding image is similar to the function of a yellow light in a traffic light, and reminds a driver to pay attention to pedestrians in the pedestrian crossing 13 in front and pay attention to slow down.

When control 32 determines that crosswalk 13 is unoccupied, there may be multiple ways of handling. For example, one way is that the control member 32 does not act, i.e., the control member 32 does not control the display member 35 to display any image, which avoids unnecessary interference with the driver and saves energy. Alternatively, the control unit 32 may also control the display unit 35 to display a security image, which may be a picture, a text, a video, an animation, etc., without limitation. For example in the form of "unmanned". The safety image is similar to the function of a green light in a traffic light, informs a driver that no pedestrian exists in the pedestrian crossing 13 in front of the driver, and can normally pass without slowing down and crawling.

It should be understood that the road safety monitoring device disclosed by the invention is mainly suitable for roads in remote areas such as suburbs or rural areas, and under the condition of few pedestrians, in a preset time period at night, if the road safety monitoring device disclosed by the invention determines that a pedestrian exists at the crosswalk 13, the device can remind the driver of the automobile 40 of slowing down and crawling, so that accidents caused by the pedestrian hitting the crosswalk 13 are avoided, if no pedestrian exists, the driver of the automobile 40 can drive at ease without slowing down, and the safety and the driving efficiency are both considered.

For roads in the central area of the city, there are many pedestrians on the roads, and it is possible that frequent pedestrians walk across the pedestrian crossing 13, the road safety monitoring device of the present disclosure is also applicable, but has limitations, on one hand, lights on the roads at night in the central area of the city are usually sufficient, light conditions are good, the driver of the automobile 40 can basically see the situation at the pedestrian crossing 13 at a distance, on the other hand, the driver of the automobile 40 is also required to decelerate and crawl across the pedestrian crossing 13 in the urban traffic management regulations.

On the road in current remote area, when light condition is not good at night, the driver sees the condition in distance clearly, it has the pedestrian to go to just can see on the cross walk 13 when very near to cross walk 13 easily, step on the brake again in an urgent need, often can take place to stop and can't hit the pedestrian's the condition, or even brake, but driver and passenger in the car 40 can topple over forward because of inertia, driver's driving safety sense is poor, passenger's experience by bus is poor.

In the disclosure, since the reminding image displayed by the display part 35 informs the driver that a pedestrian exists at the pedestrian crossing 13 in advance, the driver can receive the reminding in advance and take measures to slow down and walk slowly in time, so that the situation that the driver steps on the brake suddenly after the driver is very close to the pedestrian crossing 13 is avoided, the automobile 40 is prevented from colliding with the pedestrian, the driving safety of the driver can be improved, and the riding feeling of passengers is improved.

In a word, in this disclosure, in the preset time period at night, when the light condition is not good, the image information of the pedestrian crossing 13 is obtained by the detection piece 31, and after the control piece 32 analyzes and processes the image information, whether a person is at the pedestrian crossing 13 can be determined, if a person is at the pedestrian crossing 13, the display piece 35 can be controlled to display a reminding image, and the reminding image plays a role in reminding the driver of the automobile 40, so that the driver can take measures to slow down and walk in advance, and accidents caused by the fact that the pedestrian is collided at the pedestrian crossing 13 are avoided.

Optionally, the detecting element 31 may be any one of a visible light camera, an infrared camera, a thermal imager, and a radar.

Specifically, when there is a bright street light in the crosswalk 13, the visible light camera can take a clear picture, which can be used as image information for the control unit 32 to analyze and process, and obtain a conclusion as to whether there is a person in the crosswalk 13.

When the street lamp at the crosswalk 13 is dim or no street lamp exists, the infrared camera can shoot the picture of near infrared light close to visible light, the thermal imager can obtain the picture of far infrared light, and the picture of near infrared light or far infrared light can be provided for the control part 32 to analyze and process, and the conclusion that whether people exist on the crosswalk 13 is obtained. It can be appreciated that thermal imagers are superior to infrared cameras in fog.

The radar can acquire a radar image at the crosswalk 13 by transmitting and receiving electromagnetic waves, and the radar image can be used as image information for the control unit 32 to analyze and process and obtain a conclusion whether a person is on the crosswalk 13. The radar may be millimeter wave radar, and may be used in foggy weather.

It is understood that the detecting member 31 may be of other types, and is not particularly limited.

The types of the detecting members 31 may be selected as needed in a specific situation. For example, a bright street lamp is arranged on the pedestrian crossing 13, and a visible light camera can be selected for a road without fog all the year round, so that the cost is low. The infrared camera can be selected for the road with dim street lamps or without street lamps at the crosswalk 13 and basically without foggy days all the year round, and compared with a thermal imager or a radar, the cost is low. The street lamps at the pedestrian crossing 13 are dim or have no street lamps, and the thermal imager or the radar with higher cost can be selected for the roads with more foggy days all the year round, so that the detection reliability is ensured.

Therefore, the purpose of acquiring the image information of the pedestrian crossing 13 can be achieved by setting the detection piece 31 to be any one of a visible light camera, an infrared camera, a thermal imager and a radar, and the types are mature products in the market, are easy to obtain and do not need development cost.

Specifically, the first supporting portion 211 and the second supporting portion 212 are both substantially rod-shaped, and the first direction is, for example, a vertical direction, and the extension in the circumferential direction is reduced as much as possible, so as to reduce the occupied space and avoid affecting the running of the automobile 40 or the walking of pedestrians. The second direction is, for example, a horizontal direction, or has an inclined angle with the horizontal direction, and the angle between the first direction and the second direction is greater than or equal to 90 °, such as 90 °, 120 °, 135 °, and the like. The end of the second support portion 212 may be connected to the end of the first support portion 211, the end of the second support portion 212 may be connected to the middle upper portion of the first support portion 211 instead of the end, or the position of the first support portion 211 near the end may be connected to the end or the middle upper portion of the second support portion 212, without limitation. The first supporting portion 211 and the second supporting portion 212 may be detachable structures that are connected and fixed by a screw connection, a snap connection, or the like, or may be non-detachable structures that are welded or integrally formed.

By providing the first support portion 211 and the second support portion 212, the purpose of supporting the detecting member 31 can be achieved with a simpler structure, and at the same time, the influence on the running of the automobile 40 or the walking of a pedestrian can be reduced.

By arranging the host 30 to integrate the control member 32 and the detecting member 31, the structure is compact, and the host 30 is provided with an opening, so that the detecting member 31 can conveniently acquire the image information of the pedestrian crossing 13.

Alternatively, referring to fig. 1, the roadway 11 includes a forward lane 111 and an opposite lane 112, the crosswalk 13 spans the forward lane 111 and the opposite lane 112, the forward lane 111 and the opposite lane 112 are separated by a partition 113, and the display member 35 is disposed on a side of the forward lane 111 facing away from the opposite lane 112 in the traveling direction of the automobile 40, or the display member 35 is disposed on the partition 113.

As shown in fig. 1, if the automobile 40 travels in the right lane shown in fig. 1, the right lane is the forward lane 111, and the left lane is the opposite lane 112, according to the traveling direction of the automobile 40; when the automobile 40 travels in the left lane shown in fig. 1, the left lane is the forward lane 111, and the right lane is the opposite lane 112. The car 40 is traveling in the forward direction 111, as in fig. 1, the car 40 is traveling in the direction indicated by the arrow in the right lane, the car 40 in the opposite lane 112 is also traveling in the direction indicated by the arrow in that lane, and the directions of the forms of the cars 40 in the two lanes are opposite. It is understood that the arrangement of the lanes varies throughout the world due to different traffic laws. In summary, regardless of how the lanes are arranged, the positions where the display 35 is arranged need to satisfy: the vehicle 40 travels to the position of the display 35 and then to the crosswalk 13.

If the vehicle 40 is traveling in the right lane, which is the forward lane 111, as shown in fig. 1, the display 35 is disposed on the side of the right lane facing away from the left lane in fig. 1, on the side of the forward lane 111 facing away from the opposite lane 112.

The isolation belt 113 may be a physically isolated structure, such as a green belt, a railing, a tree, etc., or a structure without physical isolation, such as a solid line drawn on the ground, etc.

The display member 35 is disposed on the side of the forward lane 111 opposite to the opposite lane 112 or the isolation belt 113, so that the driver can easily see the display member to play a role of reminding.

Optionally, referring to fig. 1, fig. 2 and fig. 4, the display 35 includes a support rod 351 and a display screen 352, one end of the support rod 351 is fixed on the ground, the other end opposite to the support rod is provided with the display screen 352, and the display screen 352 is electrically connected to the control member 32 for displaying the reminding image.

The support rod 351 is substantially rod-shaped, and may also extend substantially along the first direction, and the support rod 351 has a certain length, so that the display screen 352 may have a certain height, such as 1m, 1.5m, and the like, for the driver to see. The display 352 may be a liquid crystal display, a Light-Emitting Diode (LED) display, an Organic Light-Emitting Diode (OLED) display, or the like, and is not limited in particular.

By providing the display member 35 including the support rod 351 and the display screen 352, the display screen 352 can be made to have a certain height for the driver to see.

Alternatively, referring to fig. 1 and 2, the display members 35 are multiple, and two adjacent display members 35 are spaced apart by a second spacing distance S2 along the driving direction of the automobile 40. As shown in fig. 1 and 2, the number of the display members 35 is 2. The first spacing distance S1 between the display element 35 and the crosswalk 13 is the distance between the one display element 35 closest to the crosswalk 13 and the crosswalk 13 in this embodiment. In this embodiment, the second spacing distance S2 may be equal to or different from the first spacing distance S1. In this embodiment, the second spacing distance S2 between the plurality of display elements 35 and the first spacing distance S1 may be set according to the speed of the road, and when the speed of the road is high, the first spacing distance S1 and the second spacing distance S2 may be set to be farther, whereas when the speed of the road is low, the second spacing distance S2 and the second spacing distance S2 may be set to be closer.

In the driving process of the automobile 40, if the pedestrian passes through the pedestrian crossing 13, because both have speeds, the number of the display pieces 35 is too much to set, generally speaking, the display pieces 35 are 2-4, otherwise, the driver of the automobile 40 receives the prompt to decelerate at a distance far away from the pedestrian crossing 13, however, when the automobile 40 drives to the pedestrian crossing 13, the pedestrian already passes through the pedestrian crossing 13, and thus, the driving efficiency is not improved. As shown in fig. 1 and 2, in a specific example, the number of the display members 35 is 2, the first spacing distance S1 and the second spacing distance S2 are both 50m, when the automobile 40 is running, the warning image of the first display member 35 is seen at a distance of about 100m from the crosswalk 13, deceleration is started, the warning image of the second display member 35 is seen at a distance of about 50m from the crosswalk 13, and deceleration is continued, and at the same time, the pedestrian passes through the crosswalk 13 from one side to the other side of the roadway 11, when the automobile 40 is running to the crosswalk 13, the speed of the automobile 40 is already low, the driver may have sufficient reaction time, if the pedestrian is still on the crosswalk 13, the driver may stop the automobile 40, and if the pedestrian has completely passed, the driver may not stop the automobile 40 but pass through the automobile 40.

In one embodiment, referring to fig. 1 to 4, a sidewalk 12 is disposed beside the roadway 11, the pedestrian crossing 13 is connected to the sidewalk 12, the detecting element 31 is further configured to obtain image information of at least a portion of the sidewalk 12 beside the pedestrian crossing 13, the control element 32 is further configured to determine whether the sidewalk 12 is occupied according to the image information of the sidewalk 12 provided by the detecting element 31, and when the control element 32 determines that the sidewalk 12 is occupied, the control element 32 controls the display element 35 to display a warning image.

In this embodiment, basically the same as the previous embodiment, except that this embodiment has a certain predictability that pedestrians on the sidewalk 12 near the pedestrian crossing 13 may pass through the pedestrian crossing 13, therefore, the detecting element 31 is further configured to acquire image information of the sidewalk 12 near the pedestrian crossing 13, and after analyzing and processing the image information, the control element 32 can determine whether there is a person, and if there is a person, the display element 35 displays a reminding image.
