[Preferred Embodiment of the Present Invention]

Configuration of the entire system

FIG. 1 is a view schematically showing a configuration of a movement information management system by collecting travel logs for each user according to an embodiment of the present invention.

1, the overall system according to an exemplary embodiment of the present invention may include a movement information management server 100 and a user terminal 200, and may include a time information providing server 300, A weather information providing server 400, and an advertisement information providing server 500.

The mobile information management server 100, the user terminal 200, the time information providing server 300, the weather information providing server 400 and the advertisement information providing server 500 transmit and receive data through mutual communication networks, And the communication network may be configured as a wireless communication mode, and may be configured by various communication networks such as a mobile communication network, a satellite communication network, and the like. More specifically, the communication network in the present invention is a concept that includes all known WLAN (Wireless LAN), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), or Global System for Mobile communications .

First, according to an embodiment of the present invention, the movement information management server 100 may include a communication unit 110 and a processor 120. According to one embodiment of the present invention, the communication unit 110 and the processor 120 may be program modules in which at least some of them communicate with the mobile information management server 100. [ Such program modules may be included in the mobile information management server 100 in the form of an operating system, an application program module, and other program modules, and may be physically stored on various known memory devices. These program modules may also be stored in a remote storage device capable of communicating with the mobile information management server 100. [ These program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types as described below in accordance with the present invention.

According to an embodiment of the present invention, the communication unit 110 may be configured such that the mobile information management server 100 includes a user terminal 200, a time information providing server 300, a weather information providing server 400, 500), and the like. More specifically, the user terminal 200 may receive the user location information obtained using the GPS, receive the selected travel information from the user, and receive the schedule information of the user stored in the user terminal 200 It is possible. Also, as will be described later, the processor 120 can transmit to the user terminal 200 the calculated travel path of the user, time to arrive or time to depart to observe the schedule. The weather information providing server 300, the weather information providing server 400, and the advertisement information providing server 500 can transmit and receive time information, weather information, advertisement information, and the like through the communication unit 110.

Here, the user terminal 200 according to an exemplary embodiment of the present invention is a digital device including a function of enabling communication after being connected to a communication network, such as a personal computer (for example, a tablet computer, a notebook computer, etc.) A portable digital device or a wearable device equipped with a memory means such as a personal digital assistant (PDA), a web pad, a mobile phone and the like and equipped with a microprocessor and capable of computing can be employed as the user terminal 200 according to the present invention.

Next, in accordance with an embodiment of the present invention, the processor 120 controls the operation of the communication unit 110 and controls the operation of the data between each component of the mobile information management server 100, By controlling the flow, each component is controlled to perform its own function.

More specifically, the processor 120 refers to the user location information received through the communication unit 110, and determines (i) at least a part of the moving time, the moving distance, and the residence time of the user of the user terminal 200 Information on a stay location and an arrival time corresponding to the first condition is acquired by the first travel log, and if the received user location information does not satisfy the first condition Acquiring, by a second travel log, location information corresponding to the predetermined information with reference to pre-stored schedule information corresponding to a user of the user terminal 200, and (ii) When at least a part of the travel log and the second travel log satisfy a second condition that is repeated at a predetermined frequency or a predetermined number of times or more, Groups it is possible to perform the process of storing at least some of the second travel in the travel log database 130.

For example, according to the setting of the user, it is possible to set the first condition that the moving time of the user is 10 minutes or more, the moving distance is 0.25 miles or more, and the stay time is 10 minutes or more , And if the user performs the movement satisfying the first condition, it is determined that the movement is meaningful and can be obtained as the first travel log. However, in a case where any one of them is not satisfied, it is determined that the user's schedule is stored in the user terminal 200 only for a predetermined period of time, and the second travel log can be acquired. Of course, this is only one example. If the moving time of the user is 10 minutes or more, the moving distance is 0.25 miles or more, and the residence time is 10 minutes or more, .

Meanwhile, when the processor 120 satisfies a second condition that at least a part of the first travel log and the second travel log is repeated at a predetermined frequency or a predetermined number of times or more, the first travel log and the second travel log At least a portion of the travel logs may be stored in the travel database 130. For example, the travel logs may be stored at least twice a day, at least three times a week, at least four times a month, at least five times at three months, Alternatively, a travel log that is repeated 10 times or more per year may be stored and managed in the travel database 130.

However, even if at least a part of the first travel log and the second travel log are repeated at a frequency not satisfying the second condition, the travel log is stored in the travel database 130 from the user terminal 200 The processor 120 may store the travel log in the travel database 130. In this case,

The processor 120 may acquire movement pattern information by applying a machine learning process to the data stored in the travel database 130. The machine learning process is similar to the big data analysis in that it collects and analyzes the data and predicts the future by analyzing the large data of the generation, the period, and the format of the data. It is a field of artificial intelligence, and it is attracting attention as a big data core technology.

The processor 120 estimates the travel route of the user based on the travel pattern information of the user stored in the travel database 130 on the basis of the travel log, And instructs the user terminal 200 to transmit departure time information for arriving at the arrival time to the destination.

To this end, the processor 120 may be configured to (i) obtain spatial information and altitude information from the user terminal 200, (ii) receive mobile means information selected from the user terminal 200, And the altitude information to calculate the walking distance or the traveling distance using the traveling means, and calculate the expected arrival time. The spatial information may include the user's latitude and longitude information obtained using GPS, and the altitude information may be the current altitude from the ground on which the user is located, the number of layers in the building, or the altitude or layer number information of the destination. For example, if the user is located on the 10th floor of the building, the time required to ride down the elevator from the 10th floor to the ground, the time to move from the ground to the vehicle when the vehicle is assumed to travel, The estimated arrival time can be calculated in consideration of the time taken to walk from the parking lot to the destination after parking, and the like. Of course, altitude information is not necessary here.

On the other hand, the movement information management server 100 judges whether or not the expected movement time of the user is from the time information providing server 300 to an event for delaying the commute time, the scheduled arrival time on the movement path, The moving distance and the estimated arrival time can be calculated by receiving information on whether the user is eating or snacking time in consideration of the life pattern of the user.

More specifically, when the expected travel time is the meal time zone, the mobile information management server 100 calculates the expected meal time of the user considering the lifestyle of the user using the travel database 130, The expected arrival time can be calculated in consideration of the estimated time of eating.

When the expected travel time is the meal time, the mobile information management server 100 receives an event coupon available from the restaurant located on the estimated travel route from the advertisement providing server 500, To the user terminal 200. Accordingly, the mobile information management server 100 can obtain advertisement revenue from a restaurant or the like and increase sales of a restaurant or the like, and the user can enjoy a meal at a discounted price.

On the other hand, the movement information management server 100 receives weather information including at least one of the expected amount of movement, the snowfall amount, and the temperature of the travel time from the weather information providing server 400 and calculates the travel distance and the estimated arrival time .

The time information providing server 300, the weather information providing server 400 and the advertisement information providing server 500 may include a communication unit (not shown) and a processor (not shown). According to one embodiment of the present invention, the communication unit and the processor may be program modules in which at least some of them communicate with the respective server 300, 400, 500. These program modules may be included in each of the servers 300, 400, and 500 in the form of an operating system, an application program module, and other program modules, and may be physically stored in various well-known storage devices. These program modules may also be stored in a remote storage device capable of communicating with each of the servers 300, 400, Such program modules, on the other hand, encompass but are not limited to routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or execute particular abstract data types in accordance with the present invention.

The communication unit constituting each of the servers 300, 400, and 500 performs a function to communicate with an external system such as the mobile information management server 100, and the processor controls the operation of the communication unit, By controlling the flow of data from / to each of the servers 300, 400, and 500 or each of the servers 300, 400, and 500, respectively.
