According to the present invention, when the user terminal transmits the starting point and end point information of the vehicle's movement route to the navigation servo, the weather information on the movement route, which is transmitted to the user terminal by combining the arrival time point of each section and the arrival time point information of the section on the movement route. It is about a provision method.
Hereinafter, a method for providing weather information on a movement route according to the present invention will be described in detail with reference to the accompanying drawings.
1 shows a flow chart of a method for providing weather information on a movement route according to the present invention, and FIG. 2 shows a user terminal, a navigation server, and a weather forecast in the method for providing weather information on a movement route according to the present invention. A block diagram illustrating the relationship between servers is shown.
As shown in FIG. 1, the method of providing weather information on a movement route according to the present invention includes the steps of: (a) transmitting, by a user terminal, information on a movement route to a navigation server; (b) the navigation server receiving the time / end information and searching for a movement path; (c) measuring, by the navigation server, each time point of arrival (hereinafter, referred to as “segment time”) when the vehicle is driven on the movement path, and requesting weather information for each time point from the weather forecast server; ; (d) collecting, by the weather forecast server, the weather information for each section time point and transmitting it to the navigation server; (e) the navigation server combining the movement route information and the weather information for each section time point and transmitting the combined route information to the user terminal; Characterized in that it comprises a.
In the method for providing weather information on the movement route, including the steps (a) to (e), the user terminal, the navigation server, and the weather forecast server exchange information as shown in FIG. 2. First, the user terminal first transmits the start point and the end point information in the moving path of the vehicle to the navigation server. The navigation server receives the starting point and end point information, measures the time point of the section on the movement route, requests the weather information from the weather forecast server, receives the weather information from the weather forecast server, a combination of the movement route information and the weather information for each section time point, and the user terminal. It is responsible for transmitting the combination information to the furnace. Meanwhile, the weather forecast server is responsible for receiving the weather information collection request for each section time, collecting weather information for each section time, and transmitting the collection information to the navigation server.
Hereinafter, each step of the method for providing weather information on the movement route according to the present invention will be described in detail.
1.step (a)
In this step, the user terminal transmits the start point and the end point information to the navigation server in the vehicle's movement path.
In the present invention, the user terminal is used to collectively mean any device capable of exchanging information with the navigation server through wired or wireless communication. That is, everything from desktop PCs and notebook PCs to smartphones, tablet PCs, and car navigation devices.
In order to exchange information between the user terminal and the navigation server, it is also possible to connect via web browsing, and the user terminal may exchange information with each other while being synchronized with an application program provided by the navigation server. In the case of recent smartphones, tablet PCs, etc., when the web browsing method is used, the connection through the mobile web will be preferable in consideration of the efficiency of information exchange, and the synchronization by the application program will be easier. On the other hand, in the case of navigation installed in a vehicle, it is generally synchronized with a program provided by the navigation server.
The user connects to the navigation server through a web browsing method or an application program execution method through his / her user terminal via a wired or wireless connection, and transmits the start point and the end point information of the moving route which is to be operated by the vehicle to the navigation server. For example, if you are going to operate from Seoul to Busan, you can enter Busan as the end point in Seoul, and you can also enter details by city or town. On the other hand, as an input method, direct text input may be possible according to the environment of a web page or an application program, and automatic input method through a map or a place name search may be possible. Since weather forecasts are currently being made in detail up to a regional range of about 5㎢, the point and end information should be as detailed as the county, town, or district.
2. Step (b)
In this step, the navigation server receives the time / end point information and searches for a movement route.
This is done according to a method performed in a typical navigation information service such as general vehicle navigation or pathfinding service in various portal sites. Based on the time / end point information received from the user terminal, the shortest route search or the shortest route search in consideration of traffic conditions may be possible.
In order to search for an efficient movement route, the navigation server may be linked with a real-time traffic information system operated by a local government or a road traffic corporation.
3. Step (c)
This step is a step in which the navigation server measures the interval time point when driving the vehicle on the movement route, and requests the weather information for each interval time point to the weather forecast server.
The navigation server divides the sections on the movement route after searching for the movement route in step (b), and measures the point of time of the section, that is, the time of arrival of the sections, when the vehicle is running. The measurement of the point of time of the section is for deriving guide information for the movement route, and also for determining what weather information is needed for each section of the movement route.
As a method for measuring the point of time of the navigation server, first, there is a method of collecting real-time traffic information on a moving route, calculating an average moving speed for each section, and measuring the average moving speed for each section. Since this method uses the current information, it can reflect the current road situation well. However, since the traffic volume at the time when the user passes the corresponding section may be different, an error due to the difference between the measurement point and the passage point is inevitable.
In addition, the navigation server collects traffic information for a specific period by the navigation server to measure the time point of the section, constructs an average moving speed database for each day, time zone, and section, and then extracts the day, time, and interval from the database. There is also a method for measuring based on average moving speed information. This is a way to predict the present pattern by analyzing the past pattern. This measures the interval time based on the past average moving speed of the time when the user is expected to pass through a specific interval, thereby reducing the error resulting from the difference between the measurement time and the passing time. However, this method has a disadvantage in that it does not faithfully consider variables due to special situations such as traffic accidents and construction.
In addition, the navigation server measures the time point of the section, and the navigation server collects, calculates and measures real-time traffic information, and collects traffic information for a specific period to build an average moving speed database for each day-time zone-section. There is a method of using a method of measuring based on average moving speed information for each day-time zone-section extracted from the database. Specifically, the time point of arrival to the first arrival section is measured by collecting the real-time traffic information for the first arrival section and calculating the average speed of the section. In the case of the first section of the movement route, the difference between the time of measurement and the time of passage of the user is small, so that the measurement can be performed with little error from the difference between the two time points. On the other hand, for the subsequent sections, the time point of each section is measured based on the average moving speed for each day-time zone-section extracted from the database. After the second section, the difference between the time of measurement and the time of passage of the user occurs to some extent because the measurement based on the past pattern is more likely to be more accurate. Such a hybrid method can be said to take advantage of both the real-time calculation method described above and the database extraction method.
On the other hand, the navigation server measures each section time through the above-described method and requests the weather information for each section time from the weather forecast server. The diary information for each point of time may be regarded as a set of data composed of two regions and time for which diary information is needed. For example, when the point of view on the movement route is A and the end point is C, the result of the navigation route search result of the navigation server is divided into the AB section and the BC section. When the estimated point C arrival time is derived at 2 pm, the navigation server transmits two pairs of data (B, 11 am) and (C, 2 pm) to the weather forecast server.
4. Step (d)
In this step, the weather forecast server collects weather information for each section time point and transmits the weather information to the navigation server.
The weather forecast server may be a server of a weather forecasting institution such as a meteorological office, or may be a server of a company that receives and distributes weather forecast information. In order to effectively provide a method for providing weather information on a movement route according to the present invention, the weather forecast server should have weather information of a unit of a county or a district or less and a time of 2-3 hours or less. The local weather forecast (digital forecast) provided by the Korea Meteorological Agency currently forecasts the weather every three hours for every 5km x 5km grid.
The weather forecast server receives information on a region and time for which weather information is needed from the navigation server and collects the information. As in the example of step (c) above, when the two pairs of data are received from the navigation server (B, 11 am) and (C, 2 pm), the weather forecast server is 11 am at the point B. We will collect weather information and information at 2:00 pm at branch C.
The weather information does not exist for every place name or time point, and generally exists for a certain time interval for a certain area range. Therefore, if the place name received from the navigation server does not exist in the weather forecast minimum area area name, the weather forecast server does not exist. It must match with the corresponding weather forecast minimum area, and have the data classification information and the processing capability to categorize and process the time point received from the navigation server by the weather forecast minimum time unit.
The weather forecast server transmits the weather information for each section time point to the navigation server.
5. Step (e)
In this step, the navigation server combines the movement route information and the weather information for each section time point and transmits them to the user terminal.
When the navigation server receives the weather information for each section time point from the weather forecast server, the navigation server combines the weather information for each section point with the movement route information searched by the navigation server and transmits the weather information to the user terminal. In the following, the examples described in steps (c) and (d) will be described below. The weather forecasts for (B, 11 AM) and (C, 2 PM) that the navigation server transmits to the weather forecast server are as follows. When receiving the weather information for each point of time (B, 11 AM, sunny) and (C, 2 PM, showers) from the server, the navigation server, along with the ABC travel information, is expected to pass through B point 11am- The combination information of sunny and point C estimated arrival time 2 pm-shower is transmitted to the user terminal.
As described above, the user inputs only the start point and the end point information to the user terminal through the method for providing weather information on the movement route including the steps (a) to (e) described above, and thus the section search information and the route point of the movement route. You will be able to receive comprehensive weather information. Such a method of providing weather information on a moving path may be regarded as a model for producing and distributing high-quality high-quality information in an information age in which the amount of information is increasing dramatically.
The present invention has been described above with reference to the accompanying drawings. However, in addition to the embodiments of the drawings, various modifications and variations are possible without departing from the spirit of the present invention, and may be used in various fields. Therefore, the claims of the present invention include modifications and variations that fall within the true scope of the invention.
