Description

{Method for Providing IoT Sensor Network Platform For Collecting and Providing Road information}

Various embodiments of the present invention provide an IoT sensor network platform that collects and provides road information. In particular, it monitors road conditions and collects and shares information on disasters and accidents such as natural disasters or traffic accidents so that it can respond to them.

Real-time monitoring of road conditions is essential for safety and smooth vehicle operation. In particular, it is important to detect accidents occurring on the road or road icing and to provide information on it, in that it can prevent secondary accidents by inducing users to recognize the reason for delay and take appropriate measures accordingly. do.

However, most of the existing monitoring means used expensive equipment, and it was difficult to provide monitoring results and feedback in real time.

Recently, various sensor devices with stable and low prices have been produced and sold, and IoT technology capable of connecting various sensor terminals through a network has been developed and disseminated.

The Internet of Things (IoT) is also called the Internet of Things, and refers to a technology or environment in which data can be exchanged with a server in real time through a network by attaching sensors and communication modules to objects. The existing IoT was understood as a model controlled by a central server, but recently, an IoT system based on cloud computing has also been widely developed and provided.

Cloud service has been developing by providing optimized technology for data processing and storage in response to environmental changes that require miniaturization of devices such as smartphones and advancement of processing operations.

Accordingly, cloud service users were able to have a reasonable cost structure through a usage-based payment structure. However, problems such as server stability, security, and response speed still remain.

In particular, in industrial IoT, huge data that needs to be processed and stored often needs to maintain urgency, accuracy, and security. In this case, there is a limit to data processing only with the current cloud computing technology.

Accordingly, the concept of fog computing, which extends cloud computing and services to the edge of the network, was introduced, and the concept of using individual devices (Edge) rather than a centralized network system was introduced.

Edge computing enables data processing directly from IoT objects, so it has lower computing power compared to cloud computing, but has the advantage of fast response and no need for broadband communication. Edge computing means placing processors and data near the ends (endpoints) rather than sending them to the center (the cloud).

Edge computing is a technology that guarantees immediacy and stability compared to the cloud because it can immediately analyze data at the end (edge) where data is collected and apply it to the field.

Therefore, there is a need to develop a system capable of judging road conditions in real time and providing feedback by using these technologies.

In various embodiments, when the pattern of sensor data is an event occurrence pattern (eg, when the pattern of standing data has a pattern that appears when an event occurs), the computing device 100 determines that an event occurs within a predetermined area. can be judged as However, the present invention is not limited thereto, and various methods for determining whether an event has occurred may be applied.

In step S140 , when the occurrence of the event is detected through step S130 , the computing device 100 may determine the cause of the occurrence of the event.

In various embodiments, the computing device 100 uses temperature data sensed from the sensor 300 (eg, external temperature data sensed from an external temperature sensor and internal temperature data sensed from an internal temperature sensor) to freeze the road surface. can determine whether For example, when the sensor 300 includes an external temperature sensor disposed outside the housing and an internal temperature sensor disposed inside the housing, and the occurrence of an event is detected through step S130, the computing device 100 may Based on the change trend of the temperature data (external temperature data and internal temperature data) and two temperature data, it is possible to determine whether the road surface is frozen.

In various embodiments, the computing device 100 may extract one or more parameters from two temperature data and determine whether the road surface is frozen by using the extracted one or more parameters and a pre-trained learning model.

Here, the pre-learned learning model is the external temperature data detected from the external temperature sensor, the internal temperature data detected from the internal temperature sensor, and data on whether the road surface is frozen at the time when the external temperature data and the internal temperature data are detected. As training data, it may mean a trained model. However, the present invention is not limited thereto.

In various embodiments, the computing device 100 may determine whether an accident has occurred using lidar sensor data detected from the sensor data 300 . For example, when the sensor 300 includes a lidar sensor and the occurrence of an event is detected through step S130, the occurrence of an accident within a predetermined area is determined using lidar sensor data detected from the lidar sensor. It is possible to determine whether there is an accident and the location of the accident.

In various embodiments, the computing device 100 may analyze sensor data to determine the type and grade of a cause of the event. For example, the computing device 100 determines whether the road surface is icing based on the change trend of two temperature data (external temperature data and internal temperature data) and two temperature data measured from the sensor 300, Depending on the degree of icing, it is possible to set a class (eg, icing caution class, icing warning class, icing hazard class, etc.).

In step S150 , the computing device 100 may output a guide message including a cause of occurrence of the event determined in step S140 and guide information according to the cause of occurrence. For example, the computing device 100 includes a milestone display device 200 disposed in a predetermined area, a user terminal 20 positioned within a preset range based on a location where the occurrence of an event is detected, and an infotainment system of a vehicle. A guide message is provided to at least one so that the guide message is output on the display included in the signpost 200, the guide message is output on the display included in the user terminal 20, or included in the infotainment system of the vehicle A guide message may be output to a displayed display device (eg, navigation). However, the present invention is not limited thereto.

In various embodiments, the computing device 100 may output different guide messages according to the type of the occurrence cause of the event determined in step S140 .

In various embodiments, when the cause of the occurrence of the event determined in step S140 is icing on the road surface, the computing device 100 provides a guide message for guiding slow driving of the vehicle according to whether the road surface is icing and whether the road surface is icing. output (eg, FIG. 8(a)).

In various embodiments, when the cause of the occurrence of the event determined in step S140 is an accident, the computing device 100 provides a guide message for guiding slow driving of the vehicle or guiding a change of lane according to whether or not an accident has occurred and the occurrence of the accident can be output (eg, FIG. 8(b)).

In various embodiments, the computing device 100 may determine an output method of the guide message according to the type of the cause of the event. For example, the computing device 100 may set different colors of the guide message text output according to the type of cause of the event (eg, accident occurrence and icing on the road surface) to be different from each other (eg, icing on the road surface). You can set the guidance message according to the accident to blue and the guidance message according to the accident to red).

In various embodiments, the computing device 100 may determine an output method of the guide message according to the class of the cause of the event. For example, when the icing information on the road surface is the icing caution grade, the computing device 100 may output only a guide message guiding whether the road surface is icy and slow driving of the vehicle. In addition, when the icing information on the road surface is an icing warning grade, the computing device 100 increases the size of an area in which a guidance message guiding whether the road surface is icing and slow driving of the vehicle is output, and the output guidance message is You can make it blink. Also, when the icing information on the road surface is an icing risk grade, the computing device 100 may output a sound and a guide message for guiding whether the road surface is icy and slow driving of the vehicle. However, the present invention is not limited thereto.

In various embodiments, the computing device 100 outputs a guide message including a cause of occurrence of an event and guide information according to the cause of the occurrence on the display of the milestone device 200 disposed in a predetermined area, but previously output It is possible to change the information on the signpost currently being processed into a guide message and print it out. At this time, the computing device 100 may maintain the output state of the guide message until no event is detected within a predetermined area, and when the event is not detected, the guide message being output may be changed to signpost information and output. have.

In an embodiment, the computing device 100 outputs a guide message including a cause of occurrence of an event and guide information according to the cause on the display of the milestone indicator device 200 disposed in a predetermined area, but previously output It is possible to adjust the output format of the guide message according to the information on the signpost being made.

For example, as shown in FIG. 5, when it is desired to display information such as “freeze delay deceleration” as shown in FIG. 8 at a position where the milestone information of “124.6” should be displayed, while the information is displayed There may be a problem that it is difficult to check the milestones at the location.

In particular, in the case of a vehicle equipped with an autonomous driving system or an image analysis-based driving guidance system, the vehicle's location can be determined by recognizing a milestone while driving. It is necessary to set the display method so that the milestone information can be recognized at the same time in addition to the event information.

However, when the event information and the milestone information are simply displayed at the same time, the readability of the information may be deteriorated, and a display having a high resolution may be required to increase the readability.

In one embodiment, the display method of the milestone information is a method of displaying the initial three-digit number (eg, 124) according to the position, and then sequentially displaying the number of the unit below the decimal point (eg, 124.2, 124.4, 124.6, 124.8) ) can be applied. In this case, the number of characters in which event information is displayed may be adjusted according to the number of decimal places of the milestone information displayed at each position.

For example, "Freeze" for position 124.2. In the case of position 124.4, "icing deceleration", in position 124.6 "icing delay deceleration", in the case of position 124.8 "icing delay deceleration caution", etc., the same information is conveyed, but by changing the number of displayed characters, the driver or Automated systems can help locate the vehicle.

In another embodiment, as described above, the milestone information may consist of 4 numbers, but is not limited thereto. For convenience of explanation, when a case consisting of four numbers is described, the computing device 100 adds a general caution phrase such as "caution" or "warning" when the displayed event information is less than 4 characters to provide event information You can correct the number of characters to 4 or more.

Through this, the number of characters of the displayed event information becomes 4 or more, and the computing device 100 may express the number through the ji (-) or in (ㅣ) component of the vowel included in the displayed 4 characters. If a letter contains both the ji (ㅡ) and the in (ㅣ) components, a number can be expressed using a longer component.

For example, the computing device 100 may express a number by turning off the number of LEDs as many as the number to be expressed with respect to a component for which the number is to be expressed.

For example, in the case of "freeze delay", a number can be expressed by using the phosphorus (ㅣ) component of all four letters, and in the case of 124.6, an LED that displays the phosphorus (ㅣ) component of "grain" Turn off one of the LEDs, turn off two of the LEDs representing the in (l) component of "Bing", turn off 4 of the LEDs representing the in (l) component of "Ji", and turn off "Yeon" A number can be expressed by turning off 6 of the LEDs displaying the in (ㅣ) component of the , but is not limited thereto.

In various embodiments, the computing device 100 may provide the user terminal 20 with a UI for visualizing and outputting analysis result data generated by analyzing sensor data as big data. For example, as shown in FIGS. 9 and 10 , event occurrence detection data and event occurrence cause analysis data generated by analyzing sensor data and sensor data for a predetermined region are visualized, and various visualized data are combined into one. By configuring and providing a screen, there is an advantage in that a UI that enables a user to effectively monitor a road condition for a predetermined area can be provided.
