Description

Road sign

Technical Field

The application relates to a road sign field of instructing, particularly, relates to a road sign.

Background

With the rapid development stage of society, some remote rural areas have also come into the era of rapid development of economy. Meanwhile, with the development of economy in rural mountainous areas, the traffic flow of some rural mountainous areas is increased. However, the roads in mountainous areas in rural areas are relatively tortuous or winding. That is, there are many curves, and therefore, after the vehicle flow rate increases, the probability of a traffic accident occurring at the curve also increases. And because the curve road is narrower, when an accident occurs, the conditions such as blockage are often caused, and the traveling efficiency of people in rural mountainous areas is also influenced.

Through research on the reasons for the occurrence of traffic accidents, it is found that most traffic accidents are caused by the fact that the speed of vehicles is too fast. Since a mountain road is narrow and a vehicle does not know whether an opposite vehicle is coming at a curve, a collision with the opposite vehicle is likely to occur when the speed of the vehicle is excessively high. Meanwhile, the phenomenon of rollover of the vehicle and the like easily occurs due to the fact that the vehicle is too fast.

For these traffic accidents, it is adopted in the prior art to add a sign (road sign) at the curve to remind the driver of the vehicle coming and going to control the speed of the vehicle. However, when the environment is dark (at night or in the evening), the vehicles are often neglected to drop the road signs, and thus the traffic accidents at the curves in the mountainous area are reduced after the road signs are added, but the effect is remarkable. It can be seen how to reduce the probability of occurrence of traffic accidents in mountainous areas, which becomes an urgent problem to be solved.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a road sign 10 provided in an embodiment of the present application, and fig. 2 is a block structural diagram of the road sign 10 provided in the embodiment of the present application, where the road sign 10 includes: housing 50, display screen 130, battery 120, camera module 110, and processor 100. The processor 100 and the storage battery 120 are all accommodated in the shell 50, the display screen 130 and the camera module 110 are embedded on the shell 50, the display screen 130, the processor 100 and the camera module 110 are all connected with the storage battery 120, and the display screen 130 and the camera module 110 are connected with the processor 100. The camera module 110 is configured to acquire vehicle information of a road and send the vehicle information to the processor 100, and the processor 100 is configured to control the display screen 130 to display road sign information and/or warning information based on the vehicle information.

In some embodiments, the housing 50 of the road sign 10 may be made of plastic steel, which has a strong corrosion resistance and is suitable for a humid environment in a mountain area, so as to prolong the service life of the road sign 10. The storage battery 120 and the processor 100 are arranged in the shell 50, so that the storage battery 120 and the processor 100 can be better protected, and the phenomenon that the storage battery 120 and the processor 100 are exposed to the environment to affect the service life is avoided. Meanwhile, the place connected with the housing 50 through the display screen 130 can be treated with waterproof treatment, so as to prevent water from entering the housing 50 in heavy rainy weather, which affects the service life of the processor 100 and the storage battery 120. In the embodiment of the present application, the waterproof treatment may be to coat a layer of waterproof glue such as latex or silica gel on a joint where the display screen 130 is connected to the housing 50, so as to prevent moisture from entering the housing 50. Of course, in the specific embodiment, the water-proofing treatment may be performed in other manners, and is not limited in the embodiment of the present application as long as water outside the housing 50 can be prevented from entering the inside of the housing 50.

In some embodiments, the camera module 110 may be disposed at an upper portion of the housing 50, so that the road condition (whether vehicles pass through, the number of vehicles, etc.) can be better photographed due to the higher position of the camera module 110. Of course, the interface between the camera module 110 and the housing 50 may be waterproof, and the waterproof processing performed at the interface between the camera module 110 and the housing 50 may be the same as the waterproof processing performed at the interface between the display screen 130 and the housing 50. Therefore, the description thereof will not be repeated.

In some embodiments, the camera module 110 may be referred to as a camera, and the number of cameras may be chosen according to the location of the road sign 10. Such as: when the road sign 10 is located in a place where a curve is sharp, the number of the cameras can be set to be larger, and the condition of the road can be better acquired. Of course, when the road sign 10 is not in a sharp place, the number of cameras can be relatively small, so as to save cost. In the embodiment of the present application, the shooting direction and the number of the cameras are not limited, and only the camera module 110 can clearly obtain the situation of the road on both sides of the curve. Of course, the location of the road sign 10 is not limited to a curve, and in some embodiments, the road sign 10 may be located in an area where landslide or slippery occurs easily to remind the driver to drive carefully. The camera in the embodiment of the present application may adopt a camera with model number OV 7670.

In some embodiments, the display screen 130 is used for displaying road sign information and/or warning information, and the road sign information in the embodiments of the present application may refer to "information for reminding that a curve is ahead of the vehicle", "information for reminding that the vehicle is a slippery road section", "information for reminding that a collapsed road section is ahead of the vehicle", and the like. The warning information in the embodiment of the present application may refer to "information for reminding that the vehicle needs to decelerate", "information for reminding that the vehicle needs to stop", "information for reminding the vehicle of the highest speed", and the like. Furthermore, the people on the vehicle can drive the vehicle reasonably according to the road sign information and/or the warning information on the display screen 130, so as to avoid the occurrence of vehicle accidents. The display screen 130 in the embodiment of the present application may be an LED dot matrix screen, and the LED dot matrix screen is composed of LEDs (light emitting diodes), and displays characters, pictures, animations, videos, and the like by turning on and off the lamp beads. Meanwhile, the LED dot matrix screen has the characteristics of high brightness, good heat dissipation, good environmental performance (moisture resistance, cold and hot resistance and corrosion resistance), good antistatic property, large visual angle, high permeability and the like. Of course, in another embodiment, the display screen 130 may be selected reasonably according to actual situations, for example, the display screen 130 may also be a liquid crystal display screen 130. Referring to the circuit connection diagram of the LED dot matrix screen in fig. 5, it can be seen that the LED dot matrix screen has a chip model of MAX7219 CWG.

In some embodiments, when the road sign 10 is located at a curve, the road of the two sides of the curve may share one road sign 10, that is, two display screens 130 may be provided, so as to indicate and/or warn vehicles driving on the road of the two sides of the curve. Of course, the contents displayed on the two display screens 130 may be different, that is, the display screens 130 only need to perform reasonable display according to the actual situation.

In some embodiments, processor 100 may include one or more processing cores (e.g., a single-core processor (S) or a multi-core processor (S)). Merely by way of example, Processor 100 may include a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), an Application Specific Instruction Set Processor (ASIP), a Graphics Processing Unit (GPU), a Physical Processing Unit (PPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Device (PLD), a controller, a microcontroller Unit, a Reduced Instruction Set computer (Reduced Instruction Set computer), a microprocessor, or the like, or any combination thereof. The processor 100 as in the present embodiment may be a model of an Arduino Mega2560 single chip.

The following is an example of a specific application scenario of the landmark 10 to better understand the idea provided by the example of the present application. Such as: the road sign 10 is installed at a curve, and the camera module 110 is used to capture the road condition at both sides of the curve, that is, the camera module 110 can be used to capture the presence of vehicles on the road at both sides of the curve. If there is no vehicle on the road at both sides of the curve, the display screen 130 may be in a screen-off state to better save the power of the battery 120. If the camera module 110 obtains that a vehicle appears on one side of a curve, the camera module 110 can send information that the vehicle exists on the road to the processor 100, and at this time, the processor 100 can control the display screen 130 to display road sign information according with the curve condition according to the size of the pre-stored curve. That is, the landmark information displayed on the display screen 130 at this time may be landmark information of "please notice a curve ahead". In some embodiments, the camera module 110 may further obtain a speed of the vehicle, the camera module 110 sends the monitored speed information of the vehicle to the processor 100, and the processor 100 may further control the display screen 130 to display a warning message "for reminding the user of reducing the vehicle speed" if the speed of the vehicle is found to be too high. For another example, if the camera module 110 finds that there are vehicles on both sides of a curve, and when the camera module 110 sends the road conditions on both sides of the curve to the processor 100, the processor 100 may control the display 130 to display indication information of "please pay attention to the curve ahead" and "please pay attention to the vehicle ahead", and "remind the user to whistle", and the processor 100 may also control the display 130 to display warning information of "reminding the user to reduce the vehicle speed".

Of course, in an embodiment, the processor 100 may also control the display screen 130 to display the maximum speed at which the vehicle can travel and the current speed of the vehicle according to the road condition, so as to avoid the situation that the driver of the vehicle has an overspeed in a curve, and further reduce the probability of an accident.

In summary, in the embodiment of the present application, the camera module 110 obtains the vehicle information on the road, and sends the vehicle information to the processor 100, so that the processor 100 controls the display screen 130 to display information for reminding the driver of the vehicle of the need to drive cautiously, at the same time, the camera module 110 can also obtain the speed of the vehicle, and the processor 100 can also control the display screen 130 to display the highest driving speed of the road and the current speed of the vehicle, so as to more comprehensively remind the driver of the operation that needs to be executed currently, but only can remind the user of a dangerous road segment in front in the prior art, therefore, it can be seen that the road sign 10 provided in the embodiment of the present application has more comprehensive display information, can better avoid the occurrence of accidents, and compared with the conventional road sign 10, can play a good role in indicating or warning at night and in places with poor light because the display is performed through the display screen 130, therefore, the practicability is higher.

Referring to fig. 3 and 4 in combination, in some embodiments, the road sign 10 may include: and a solar power generation module 190, wherein the solar power generation module 190 is connected with the storage battery 120. That is, by providing the solar power generation module 190, it is possible to convert solar energy into electric energy and store the electric energy in the storage battery 120. Further, the trouble of frequently replacing the storage battery 120 or periodically charging the storage battery 120 can be avoided. That is, the utility of the road sign 10 provided by the embodiment of the present application is made higher.

In some embodiments, the road sign 10 may further include: and the wind power generation module 200 is connected with the storage battery 120.

Since the road sign 10 in the embodiment of the present application is mainly directed to remote mountainous areas, the sunlight may be insufficient at some locations where the road sign 10 is installed, that is, if only the solar power generation module 190 is used to charge the battery 120 at this time, the battery 120 may be insufficient in power. That is, at this time, the storage battery 120 may be charged by the wind power generation module 200, so that the wind power is generally high in a mountainous area, and further, the wind power generation module 200 may be used to convert the wind power into electric energy and store the electric energy in the storage battery 120. Therefore, it can be seen that the cruising ability of the storage battery 120 of the road sign 10 provided in the embodiment of the present application can be further enhanced by providing the wind power generation module 200 in the embodiment of the present application.

In some embodiments, the road sign 10 further comprises: temperature and humidity sensor 140, temperature and humidity sensor 140 with processor 100 is connected, temperature and humidity sensor 140 is used for acquireing the temperature and the humidity of environment.

In the embodiment of the application, the temperature and humidity sensor 140 sends the acquired temperature and humidity of the environment to the processor 100, and then the processor 100 can reasonably display the highest speed of the current road according to the current temperature and humidity condition, for example, when the temperature and humidity of the environment are higher, it is represented that the road is likely to slide at the moment, and then the highest speed of the vehicle at the moment on the road at the section can be reduced by a little; of course, when the temperature and humidity of the environment are low, the maximum speed of the vehicle on the road can be increased a little bit. It can be seen that in the embodiment of the present application, through monitoring the ambient temperature, the processor 100 can more reasonably control the display screen 130 to display the highest speed of the road, so as to further reduce the probability of the vehicle failing in this section. Meanwhile, compared with the prior art that the road sign 10 can only indicate one recommended speed, the road sign 10 provided by the application can reasonably display the highest speed (recommended speed) according to the temperature and humidity conditions of the environment, and therefore the road sign 10 provided by the embodiment of the application is more reasonable and more intelligent. The model of the temperature and humidity sensor 140 in the embodiment of the present application may be the DHT11 digital temperature and humidity sensor 140. Referring to the circuit diagram of the moderate temperature and humidity sensor 140 in fig. 6, it can be seen that the chip type adopted by the temperature and humidity sensor may be DHT11, wherein a pull-down resistor with a resistance value of 4.7K Ω is connected to the VCC port and the DATA port of the DHT11 chip to perform a protection function.

In some embodiments, the road sign 10 further comprises: and a raindrop sensor 150, wherein the raindrop sensor 150 is connected to the processor 100, and the raindrop sensor 150 is used for acquiring the rainfall condition of the environment.

In this embodiment, when the raindrop sensor 150 acquires that it is raining, information may be sent to the processor 100, and the processor 100 may reasonably acquire the highest speed of the road segment according to the rainfall condition sent by the raindrop sensor 150. Such as: when the amount of rain is large, the maximum speed of the road section can be controlled to be slightly lower due to the obstructed view of the driver of the vehicle. The higher the rainfall, the lower the maximum speed of the road section can be made. By the method, the recommended speed can be provided for the vehicle-mounted staffs more reasonably, so that the probability of traffic accidents of the vehicle on the road section can be reduced. Of course, when determining the maximum speed of the road segment, the processor 100 may combine the greenhouse condition and the rainfall condition of the environment, so that the determined maximum speed of the road segment is more accurate, and the more accurate maximum speed may not only reduce the probability of traffic accidents occurring on the road segment by the vehicle, but also may make the traveling efficiency of the vehicle higher. Such as: in the cold winter, the road surface is easy to crystallize to cause the sliding of the vehicle when the rainfall is small, so the speed is lower; in summer, when the rainfall is small, water is not easy to accumulate on the road surface, and the traveling of the vehicle is not greatly influenced. Therefore, it can be seen that the determined maximum speed is more accurate when the rainfall condition and the greenhouse condition of the environment are comprehensively considered, such as: when only the rainfall situation is considered, the determined maximum speed is 30km/h (summer), whereas the rainfall situation and the greenhouse situation of the environment are considered in combination, the determined maximum speed may be 35km/h (summer). That is, the traveling efficiency of the vehicle can be improved.

Referring to fig. 7, fig. 6 is a circuit diagram of the raindrop sensor 150 in the embodiment of the present application, and it can be seen that the raindrop sensor 150 uses a chip model LM 393. Where K1 is the probe interface of raindrop sensor 150, and the specific connections of the other interfaces of chip LM393 can be seen in fig. 7.

In some embodiments, the road sign 10 further comprises: a photoelectric sensor 160, the photoelectric sensor 160 being connected to the processor 100, the photoelectric sensor 160 being configured to sense an intensity of ambient light.

In the present embodiment, when the ambient light is strong, the stronger the current signal delivered to the processor 100 by the photosensor 160. That is, in some embodiments, the intensity of the ambient light may be detected by the photoelectric sensor 160, and when the illumination intensity is strong, the processor 100 may control the display brightness of the display screen 130 to be slightly darker, so as to save electric energy and increase the cruising ability of the battery 120. When the illumination intensity of the environment is low, the processor 100 may control the display brightness of the display screen 130 to be slightly higher, so that the content displayed on the display screen 130 can be seen by the driver. And a schematic diagram of the inside of the photosensor in the embodiment of the present application may be as shown in fig. 8.

In some embodiments, the road sign 10 further comprises: a searchlight 170, the searchlight 170 fixedly connected with the housing 50, the searchlight 170 connected with the processor 100 and the processor 100.

In the embodiment of the present application, when the ambient light is detected to be weak, that is, in a night environment, the environment may be present. At this time, in order to further improve the driving safety of the road segment and the accuracy of the camera module 110 detecting the road segment, the processor 100 may be configured to operate the searchlight 170 to illuminate the road segment. Further, when the driver of the vehicle drives the road section, the condition of the road section and the contents displayed on the road sign 10 can be clearly observed. Meanwhile, when the operation of vehicle passing is required, the traffic accidents caused by the vehicle passing can be reduced by clearly obtaining the conditions of the road sections.

In some embodiments, to reduce the loss of electrical power, the camera of the camera module 110 may be supplemented with an infrared module to put the searchlight 170 in operation to illuminate the road only when a vehicle or a pedestrian, etc. is present on the road.

In some embodiments, the road sign 10 further comprises: and the telescopic rod 80 is detachably connected with the shell 50.

In the embodiment, since the road sign 10 is installed on a mountain road, the telescopic rod 80 is used to support the housing 50, that is, to display the display screen 130 at a proper position. However, in order to allow the driver of the vehicle to better view the road marking 10 on the road, the conditions of different road sections are different, and thus the heights of the road marking 10 disposed at different curves or roads are different. The telescopic rod 80 has a certain telescopic power, and thus, the height of the road sign 10 can be adjusted. The prior art signposts 10 are supported by support rods that do not have the ability to telescope, thus possibly making some signposts 10 out of position.

Further, the occupied volume of the telescopic rod 80 in the transportation process is small, and the transportation is convenient compared with the traditional supporting rod.

It can be seen that, in the embodiment of the present application, by setting up the telescopic rod 80, on the one hand, the road sign 10 can be set up in a reasonable position, which is more convenient for the driver to watch, and on the other hand, the transportation can be facilitated. And through setting up telescopic link 80 for road sign 10 can directly descend road sign 10 through telescopic link 80 when needing to overhaul or need to change battery 120, rises it after the maintenance is accomplished, has promoted the efficiency of overhauing.

In some embodiments, the road sign 10 further comprises: and the power amplifier module 210, wherein the power amplifier module 210 is connected with the storage battery 120 and the processor 100.

The power amplifier module 210 in the embodiment of the present application may refer to a speaker, and when the vehicle speed of the vehicle exceeds the maximum speed, the power amplifier module 210 may work to remind the driver of the vehicle to pay attention to control the vehicle speed.

In some embodiments, the processor 100 may further include a timing module, where the timing module is configured to time a vehicle entering the camera shooting range of the camera shooting module 110, and when the vehicle has not left the camera shooting range of the camera shooting module 110 or has not entered the camera shooting range of the next camera from the camera shooting range of the current camera for a preset time, the processor 100 controls the power amplifier module 210 to operate, so as to remind the driver of not staying there. Of course, if the vehicle does not enter the camera shooting range of the next camera from the camera shooting range of the current camera, then it is also possible that the vehicle has a falling phenomenon, if the vehicle falls into the ditch, then the power amplifier module 210 works at this moment to remind the drivers of the rest of vehicles passing through the road section to timely deploy and rescue the vehicle with the problem (the vehicle falling into the ditch).

The power amplifier module 210 in the embodiment of the present application may be one or more microphones, one or more speakers, and an audio circuit.

In some embodiments, the road sign 10 further comprises: a wireless transmission module 180, wherein the wireless transmission module 180 is connected with the processor 100.

The wireless transmission module 180 in the embodiment of the present application may upload the current position information of the landmark 10 and the image information acquired by the camera module 110 to the terminal device. Such as: the current position information of the road sign 10 and the image information acquired by the camera module 110 can be uploaded to a monitoring room, the monitoring room can monitor the road in real time, and when the condition that rescue is needed occurs, a rescue vehicle can be arranged in time to carry out rescue on the road.
