Description

Smart safety system based on IoT}

The present invention relates to a smart safety system based on the Internet of Things. In particular, it detects vehicles based on the Internet of Things at a distance away from crosswalks on general national highways, and uses the detected vehicle information, crosswalk signal information, and user information in combination. About an IoT-based smart safety system that provides safety information to crosswalk users and reduces accidents for users of general national highways by providing crosswalk user information to distant vehicles through a remote IoT warning device. will be.

A crosswalk is a road that is prepared above a lane by installing safety signs or road signs to allow people to cross horizontally.

Traffic safety systems installed at these crosswalks range from devices that simply provide pedestrian signals in conjunction with traffic lights, to informing pedestrians of waiting locations, detecting and warning vehicles around the crosswalk, informing of remaining pedestrian signals, or providing display devices. There are devices that combine various functions, such as guiding pedestrians.

However, the various traffic safety systems installed at crosswalks are capable of obtaining situational information near the crosswalk and providing information to crosswalk users or vehicles around the crosswalk to some extent, but they do not provide information about vehicles located far from the crosswalk. There is a disadvantage in that it is impossible to provide crosswalk and situation information to sidewalk users or to vehicles for long distances.

For example, unlike high-speed national highways or national highways in urban areas, general national highways do not have a lot of vehicle traffic, and the amount of pedestrian movement is relatively small, so fewer crosswalks are installed.

Therefore, drivers who drive on general national highways often have less attentiveness than when driving on high-speed national highways or urban national highways, and users who use crosswalks installed on general national highways also do not increase their attentiveness due to the relatively small number of vehicles driving. There are many cases where people cross the crosswalk without doing so. For this reason, accidents on regular national highways often result in more dangerous situations than on high-speed national highways or urban national highways.

Accordingly, technology is required to reduce vehicle accidents that occur on general national roads.

Meanwhile, safety systems previously proposed for the safety of crosswalk users are disclosed in <Patent Document 1> and <Patent Document 2> below.

The prior art disclosed in <Patent Document 1> includes a support pole installed at a waiting area for crossing a crosswalk, a support beam formed horizontally at the top of the support pillar, and a support beam installed on the support beam to enter the crosswalk. A detector for detecting vehicles and pedestrians crossing the crosswalk, a lighting device installed on the support beam and emitting light, a warning sign installed at a predetermined distance from the support beam, and the vehicle installed on the support pillar and measured by the detector. It may include a controller that transmits the speed and presence or absence of pedestrians to the warning sign. Through this configuration, a crosswalk safety system is provided to ensure the safety of pedestrians by increasing the speed reduction effect of vehicles approaching the crosswalk.

In addition, the prior art disclosed in <Patent Document 2> includes a radar sensor device that detects vehicles approaching a crosswalk and measures their speed, a device that detects pedestrians waiting at a crosswalk, and a device that provides speeding and pedestrian caution information. Safety information can be provided to both vehicles and pedestrians by detecting people waiting at the crosswalk, pedestrians, and approaching vehicles through front safety signs, providing information to pedestrians through sound, and providing information to vehicles through display devices. By using smart sensors to provide safety information to both pedestrians and vehicle drivers, we can not only reduce the incidence of traffic accidents for the vulnerable, such as children and the elderly, but also use data collected from smart radar sensors to prevent traffic accidents at crosswalks. Analyze or use it as evidence.

However, this prior art is a technology that provides pedestrian information to vehicles approaching the crosswalk and provides vehicle information to crosswalk users for vehicles approaching the crosswalk, thereby providing pedestrian safety support. It is applied to general national roads to provide pedestrian information to crosswalk users. There is a disadvantage in that it is difficult to transmit crosswalk user information to vehicles and provide information about vehicles moving toward the crosswalk from a distance to those waiting for the crosswalk.

In particular, there are limitations in promoting the safe operation of vehicles and the safety of pedestrians by applying the prior art to general national roads where there are relatively few vehicles or crosswalk users.

First, the smart safety device 200 installed on the crosswalk 1 of a national highway and the vehicle detection and warning device 100 installed on the roadside at a considerable distance (e.g., 500 m, 1 km, etc.) are installed on the road of a general national highway. Detects driving vehicles.

Here, the vehicle detection and warning device 100 is installed on the roadside of a general national highway, and in order to be mobile and freely change the installation location, it also supplies power on its own. The vehicle detection and warning device 100 may be equipped with a coupling means so that it can be easily coupled to signs, pillars, and street trees installed on the roadside of existing general national highways.

Power can be supplied using the built-in battery or by generating its own power using a solar module.

The vehicle detection unit 102 of the vehicle detection and warning device 100 provides the driver of a driving vehicle with pedestrian situation information on a crosswalk installed at a distance, thereby reducing crosswalk accidents on general national highways.

For example, the vehicle detection unit 102 of the vehicle detection and warning device 100 detects the vehicle using a geomagnetic sensor using a 3-axis anisotropic magnetoresistance (AMR), an Internet of Things (IoT) sensor. And the vehicle detection information is transmitted to the control unit 103. Here, vehicle detection information may include vehicle detection presence information and vehicle speed information.

When vehicle detection information is received, the control unit 103 transmits the vehicle detection information to the remotely located smart safety device 200 through the communication module 104. The communication module 104 transmits vehicle detection information to the smart safety device 200 using various wireless communication methods, such as LoRa communication, CDMA communication, LTE communication, and 5G communication. In the present invention, transmitting vehicle detection information to the smart safety device 200 using LoRa communication, which enables low-power, long-distance communication, is explained as an example.

Here, the vehicle detection and warning device 100 can be installed in the upward and downward lanes of a general national highway, respectively, and the vehicle detection and warning device installed in the direction in which the vehicle is traveling is a smart safety device installed in the crosswalk in the direction of vehicle travel. Send detection information.

The smart safety device 200 generates safety information for safety using vehicle information transmitted through the vehicle detection and warning device 100 and user detection information of the crosswalk, and uses the generated safety information to crosswalk. It generates an alert to sidewalk users and drivers of vehicles on public highways in the distance, reducing accidents on public roads.

Here, the smart safety device 200 is installed close to a crosswalk on a general national highway and provides safety information for safety using the vehicle information transmitted through the vehicle detection and warning device 100 and the user detection information of the crosswalk. A master sign pole (210) that generates an alert to crosswalk users and drivers of vehicles on public highways at a distance using the generated safety information, and is subordinate to the master sign pole (210) to provide pedestrian caution warnings and vehicle approaches to pedestrians. It consists of a slave sign pole (220) that warns.

The LoRa gateway 211 provided in the master sign pole 210 receives vehicle detection information transmitted from the vehicle detection and warning device 100 and transmits it to the master integrated controller 216.

In addition, the pedestrian detection camera 213 provided in the master sign pole 210 photographs pedestrians walking on the waiting line or crosswalk and transmits the captured image information to the deep learning detector 215.

In addition, the pedestrian traffic light detection camera 214 photographs the pedestrian traffic light and transmits the captured pedestrian traffic light image to the deep learning detector 215.

The deep learning detector 215 analyzes the video signals of the pedestrian detection camera 213 and the pedestrian traffic light detection camera 214 using a deep learning learning algorithm to determine whether there are pedestrians waiting at the crosswalk waiting line. Determine whether there are pedestrians walking in. The deep learning algorithm that detects pedestrians from captured video signals can use deep learning algorithms already known in the video field. For example, RCNNs, SSD, and YOLOs algorithms, which are object detection algorithms that detect objects through intelligent image analysis from captured images, can be used. When an object (pedestrian, person waiting to walk) is detected through a deep learning learning algorithm, the object detection information is transmitted to the master integrated controller 216. In addition, the pedestrian traffic light is analyzed to extract information such as the color of the current pedestrian traffic light or the remaining pedestrian signal and transmits it to the master integrated controller 216.

The master integrated controller 216 uses vehicle detection information received through the LoRa gateway 211, information on the presence or absence of people waiting at the crosswalk and pedestrians on the crosswalk, and pedestrian traffic light information from the deep learning detector 215 to ensure safety. It generates safety information for and uses the generated safety information to reduce accidents by warning crosswalk users and general road vehicle drivers.

For example, when a vehicle is detected through vehicle detection information, warning information about vehicle approach caution is generated as safety information, a warning voice warning broadcast about vehicle approach is generated as safety information, and crosswalk warning lights are generated as safety information. It generates safety information to operate a floor-embedded warning device. In addition, pedestrian caution warning information is generated as safety information to notify vehicles approaching the crosswalk that there are pedestrians on the crosswalk. In addition, in order to warn of vehicle approach through gobo lighting, a warning message and vehicle approach speed message are generated as safety information when a vehicle approaches.

Among the safety information generated in this way, safety information including pedestrian caution warning information to be careful because there are pedestrians on the crosswalk or waiting line is transmitted to the vehicle detection and warning device 100 through the LoRa gateway 211.

The communication module 104 of the vehicle detection and warning device 100 displays pedestrian caution warning information transmitted from the smart safety device 200 through the warning display unit 105. As a result, drivers driving vehicles on general national roads can recognize the situation information of the crosswalk before approaching the crosswalk, and if a pedestrian is walking on the crosswalk or a crosswalk user is waiting in the waiting line, By recognizing this and driving safely, such as reducing vehicle speed, accidents that may occur at crosswalks located at actual distances are prevented. Here, pedestrian caution warning information can be displayed by flashing or lighting up in color using light-emitting diodes, and can be displayed using text messages.

In addition, the vehicle warning provision unit (approaching vehicle warning control unit) 218 of the master sign pole 210 installed close to the crosswalk displays pedestrian caution warning information based on the safety information output from the master integrated controller 216. This is provided to drivers of public highway vehicles approaching the crosswalk. Therefore, even the driver of a general national road vehicle who is not aware of the pedestrian situation on the crosswalk through the vehicle detection and warning device 100 is advised to pay attention to pedestrians on the crosswalk through the smart sign pole 210 from a distance before approaching the crosswalk. Through warnings, you can recognize the pedestrian situation at the crosswalk and drive safely, such as reducing vehicle speed, to prevent accidents. Here, a warning to be careful of pedestrians on the crosswalk can be provided in the form of a color or message using light-emitting diodes (LEDs).

In addition, based on the safety information output from the master integrated controller 216, the pedestrian warning provision unit 217 provides a warning about approaching vehicles, a crosswalk warning through lighting, a voice alarm that transmits a warning broadcast as a voice, and a crosswalk warning. Accidents on general national highway crosswalks are prevented by providing audio and visual warnings to pedestrians about approaching vehicles through crosswalk floor warnings embedded in the ground.

Here, the pedestrian (user) warning control unit 217 can display a warning message and the speed of the approaching vehicle when a vehicle approaches using gobo lighting. Therefore, pedestrians or those waiting to walk can recognize the speed of an approaching vehicle and estimate the time it will take to reach the current location, or quickly finish walking because speeding is dangerous, or wait at the safety line to avoid a crosswalk accident. prevent.

Meanwhile, the smart sign pole 210 uses the weather sensor 219 to detect weather information such as air temperature, humidity, wind direction, and wind speed, and the master integrated controller 216 includes the generated safety information and weather information. Crosswalk traffic information is generated and transmitted to the control server 300 through the center communication equipment 212.

The control server 300 stores the received crosswalk traffic information in a database and can be used as data to identify the cause of an accident when an accident occurs, or can be used in traffic policies to reduce accidents that occur at crosswalks on general national highways.

In addition, the above-described general national road safety information can be used for safety services for pedestrians on branch lines, and can also be used for safety services for workers in construction zones.

Figures 4 to 9 show that through vehicle detection on general national highways and situational information detection on crosswalks, drivers of general national road vehicles are provided with situational information on crosswalks from a distance before approaching the crosswalk to promote safe driving, This is an example of a scenario where pedestrians on a crosswalk are provided with information about vehicles approaching the crosswalk from a distance to prevent crosswalk accidents by paying attention to vehicle approaches.

Figure 4 is a first embodiment of a scenario for preventing accidents on general national roads. When a vehicle approach is detected from a distance, if the crosswalk pedestrian signal is green, a caution/warning about vehicle approach is issued through the user alert control unit, and the approaching vehicle is alerted. The warning control unit notifies you that you are crossing a street, so you can drive safely. If the crosswalk pedestrian signal is red, it indicates that crossing is not possible, preventing accidents caused by walking on the crosswalk when approaching a vehicle.

Figure 5 is a second example of a scenario for preventing accidents on general national roads. When the pedestrian signal is red and jaywalking is detected, the user warning control unit that jaywalking is detected and the approaching vehicle warning control unit perform the warning, respectively, to warn pedestrians and vehicle drivers. Make sure people pay attention to each other, and when the crosswalk pedestrian signal is red, it warns that crossing is not possible if there are no jaywalking pedestrians. This prevents jaywalking in advance and prevents crosswalk accidents.

Figure 6 is a third embodiment of a scenario for preventing accidents on general national roads. When a speeding vehicle is detected, information about a speeding vehicle approaching and information about the impossibility of a crosswalk are displayed through the user warning control unit, and the front crosswalk is blocked through the approaching vehicle warning control unit. If it exists and you are walking on a crosswalk, it warns you that you are walking on a crosswalk and encourages you to drive safely or be careful, thereby preventing crosswalk accidents on general national highways.

Figure 7 is a fourth embodiment of a scenario for preventing accidents on general national roads, and is an example of a scenario in which the presence or absence of a vehicle approaching is detected by a vehicle detection and warning device installed at a distance.

Figure 8 is a fifth embodiment of a scenario for preventing accidents on general national roads, which is a scenario for preventing accidents when road construction is in progress on general national roads. A vehicle detection and warning device 100 is installed on the labacone, etc., and information on roadside construction ahead is provided using the labacone, etc. In addition, the approaching vehicle warning control unit of the smart sign pole also displays construction information on the road ahead, so that drivers of vehicles passing through the crosswalk are aware of construction on the road ahead, thereby promoting safe driving according to the construction.

Figure 9 is a sixth embodiment of a scenario for preventing accidents on general national roads, in which weather information near a crosswalk is collected using a weather sensor, and the collected weather information is transmitted to a remotely located control server. to be aware of the weather conditions at the crosswalk.

It is self-evident to those who have it.
