Description

System and method for providing navigation service using edge cloud for transportation vulnerable {System and method for providing navigation service using edge cloud for the transportation vulnerable}

The present invention relates to a system and method for providing navigation services using an edge cloud for transportation vulnerable persons such as the disabled.

As people's awareness and social systems for the socially disadvantaged, such as the disabled, develop, consideration and interest in the socially disadvantaged are increasing, and various systems are being provided for the convenience of the socially disadvantaged.

Recently, as a transportation service, route guidance services (navigation services) are provided not only for vehicles but also for walking, and real-time traffic information using public transportation is also provided. Regarding these transportation services, various transportation services such as crosswalk control, traffic signal processing in the event of an accident, emergency rescue service, taxi service for the disabled, and provision of obstacle information are needed for the transportation vulnerable such as the disabled.

However, in order to provide such diverse transportation services, massive amounts of data must be collected, stored, and processed. Centralized and integrated management of frequently generated traffic-related data may cause problems such as service delays, errors, and failures due to load.

Navigation services are location-based services, and in particular, customized services should be provided to those with transportation disabilities by reflecting various situations, such as information on obstacles that occur in real time. If an error occurs, they may experience greater confusion than the general public and, furthermore, serious accidents may occur, so the stability of the system that provides transportation services must be a priority.

Figure 1 is a configuration diagram showing a system for providing navigation services using an edge cloud for transportation vulnerable persons according to an embodiment of the present invention, and Figure 2 is a navigation service using a plurality of edge cloud servers according to an embodiment of the present invention. It is a flowchart showing the provision process, and Figure 3 is an example diagram showing each sub-route from the starting point to the destination on the map according to an embodiment of the present invention.

Referring to FIG. 1, the entire system includes a mobile terminal 10, a plurality of edge cloud servers 30-1, ..., 30-n, hereinafter collectively referred to as 30, and a central server 50.

The mobility-disadvantaged terminal 10 is a terminal device provided by a mobility-disadvantaged person, and is used to receive navigation services by connecting to the central server 50 through a communication network. For example, it may be a mobile device such as a smartphone.

The edge cloud server 30 is intended to provide services at a closer distance from the transportation vulnerable terminal 10, and is distributed and built on a regional basis. Edge cloud technology is a technology to shorten the data processing time of the central cloud and ensure low-latency services. The edge cloud periodically or frequently transmits monitoring information to the central server 50, and the central server 50 remotely controls it. By using multiple edge cloud servers 30 distributed on a regional basis, it is possible to quickly collect and analyze a vast amount of traffic data to quickly respond to unexpected situations and prevent accidents.

The central server 50 provides a navigation service using one or more edge cloud servers 30 corresponding to the location of the transportation vulnerable terminal 10.

Referring to FIG. 2, the central server 50 receives a request for route guidance from the mobile terminal 10 through the user interface, searches for a route corresponding to the entered origin and destination information using a route search module, and establishes a temporary route. creates . Then, based on the regional information of the edge cloud servers 30, a plurality of edge cloud servers 30 corresponding to the temporary route are selected as route providing servers (S210).

The central server 50 provides information about the origin/destination to the edge cloud servers 30 selected as route providing servers (S220). At this time, information about the transportation vulnerable terminal 10 (including communication information such as IP, terminal model information, transportation vulnerable information (presence of disability, type of disability, etc.)) can be provided together.

The route providing servers that have received this information create each sub-route (S230) and sequentially provide the route guidance service (240).

Referring to FIG. 3 together, when two edge cloud servers 30 corresponding to a temporary route from the origin to the destination are selected as the route providing servers, the first route providing server and the second route providing server are each the first route providing server. A sub-route and a second sub-route are created, and a navigation service corresponding to the real-time location of the transportation vulnerable terminal 10 is sequentially provided accordingly.

here,. The route providing servers work together to predict each starting point and starting point according to the route service provision order, and create a sub-route by predicting the traffic environment at the starting point for the predicted starting point.

For example, when the first route providing server providing the first sub-route creates a route from the starting point to the first stopover, it provides related information to the second route providing server providing guidance on the second sub-route. Then, the second route providing server predicts (directly predicts or predicts to the first route providing server) the time when the transportation vulnerable terminal 10 will arrive at the first stop (starting point of the second sub-route) (second sub-path starting point). (prediction) to predict the traffic environment at the start of the second sub-route and generate the second sub-route. In this way, when all sub-paths to the destination point are completed, the mobile terminal 10 can confirm the final movement path as shown in Figure 3, which is the sum of each sub-path, and the corresponding location for each location according to actual movement. You will be provided with a route guidance service by a route providing server.

According to this embodiment, by dividing the route, it is possible to provide a more accurate and stable service due to guidance based on a route generated by predicting the traffic environment at different points in time by different edge cloud servers 30.

And, according to one example, if a failure occurs among the route providing servers or a server whose load increases beyond a threshold occurs, another route providing server that is neighboring in order to the relevant route providing server performs sub-route guidance on behalf of the route providing server. For example, if the load on the second route providing server in order increases dramatically, the first or third route providing server, whichever one has a smaller load, takes over and creates a sub-route.

And, according to one example, each route providing server generates a sub-route based on the information about the transportation vulnerable terminal 10 received from the central server 50 and the real-time moving speed of the transportation vulnerable terminal 10, or as necessary. It can be changed at time. For example, if the information set in the transportation vulnerable terminal 10 includes the information of [visually impaired] and the moving speed of 20 meters per minute (20m/m) as the route guidance history, this is used to determine the sub-route. is generated, and if the moving speed of the transportation vulnerable terminal 10 measured in real time is reduced to 15 m/m, the sub-route can be changed in real time accordingly.

According to one example, when one of the route providing servers recognizes that an obstacle has occurred on its sub-path, it can create and service the entire route first. In the case of obstacles, they can be a major limitation in movement for those with mobility impairments, and furthermore, safety accidents may occur, so the route providing server in charge of the sub-route where the obstacle was found creates the entire route and guides it.

Additionally, according to another example, if there is a sub-path whose travel time compared to the total is more than a critical ratio among the sub-paths of the route-providing servers, the corresponding route-providing server takes precedence and creates and guides the entire route. In other words, if the travel time for the entire route is 1 hour, but the travel time for a specific sub-route is 45 minutes (exceeding 70%), the route providing server guiding the sub-route takes priority and creates the entire route and provides service. By doing so, the remaining route providing servers serve other users.

If a route providing server that satisfies the specific independent guidance conditions described above exists, it can independently provide a navigation service.

Figure 4 is a flowchart showing a navigation service provision process using a single edge cloud server in a specific environment performed by the central server according to an embodiment of the present invention.

Referring to FIG. 4, when the central server 50 selects the edge cloud servers 30 corresponding to the generated temporary routes as route providing servers (S410), obstacle recognition and movement are performed on each sub-path created by the route providing servers. It is checked whether there is a route providing server that satisfies the single guidance conditions described above using the time required, etc. (S420).

As a result of the confirmation, if necessary, one route providing server is controlled to create and guide the entire route in priority (S430).

A computer program stored in a computer-readable medium may be provided to perform the method of providing a navigation service using an edge cloud for transportation vulnerable persons according to the present invention described above.

In addition, the above-described method of providing navigation services using an edge cloud for transportation vulnerable persons can be implemented as computer-readable code on a computer-readable recording medium. Computer-readable recording media include all types of recording media storing data that can be deciphered by a computer system. For example, there may be Read Only Memory (ROM), Random Access Memory (RAM), magnetic tape, magnetic disk, flash memory, optical data storage device, etc. Additionally, the computer-readable recording medium can be distributed to computer systems connected through a computer communication network, and stored and executed as code that can be read in a distributed manner.

In addition, although the present invention has been described above with reference to preferred embodiments, those skilled in the art will understand the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that it can be modified and changed in various ways.
