Detailed Description
Embodiment mode 1
Fig. 1 is a configuration diagram showing an access destination determination system according to embodiment 1 of the present invention. The visiting destination judging system includes a portable terminal device 1 held by an interviewee and an information center 2 communicating with the portable terminal device 1. Although fig. 1 shows 1 mobile terminal device 1, the access destination determination system may include a plurality of mobile terminal devices 1.
The portable terminal apparatus 1 is held by an interviewee. Examples of the portable terminal device 1 include a smartphone and a tablet terminal. The portable terminal device 1 includes a GPS Positioning device 11, and the GPS Positioning device 11 receives a signal transmitted from a GPS (Global Positioning System) satellite. The GPS positioning device 11 acquires its own position information using signals received from GPS satellites. The position information of the GPS positioning device 11 includes latitude information and longitude information.
The information center 2 includes a map information storage device 21, a distance calculation device 22 that acquires position information from the portable terminal device 1, and a building boundary occupancy calculation device 23 that calculates an occupancy indicating a possibility that a visitor has visited a building. Further, the information center 2 has an access destination determination device 24 that determines a building that the visitor has visited, an access destination information storage device 25 that stores all access destination information including information of all buildings that may be visited, and a display device 26 that displays the building visited by the visitor. The map information storage device 21, the distance calculation device 22, the in-building-boundary retention degree calculation device 23, the access destination determination device 24, the access destination information storage device 25, and the display device 26 are configured by, for example, a personal computer.
The map information storage 21 stores map information. The map information stored in the map information storage device 21 includes addresses of the respective buildings and building boundary coordinates of the respective buildings.
The distance calculation device 22 calculates the distance between the building boundary coordinates of the building and the position information of the portable terminal device 1. The distance calculation device 22 calculates the distance between the building boundary coordinates of the building and the position information of the portable terminal device 1 in accordance with a preset unit time for distance calculation. In this example, the unit time for distance calculation is set to 5 minutes. The unit time for distance calculation can be changed. Further, the distance calculation device 22 calculates, for each of the plurality of buildings, the distance between the building boundary coordinates of the building and the position information of the portable terminal device 1.
Fig. 2 is a diagram showing a state in which the position information of the mobile terminal device 1 is superimposed on the map information stored in the map information storage device 21 of fig. 1, and fig. 3 is a graph showing the distance calculated by the distance calculation device 22 of fig. 1. Fig. 3 shows the distance between the building boundary coordinates of the building shown in fig. 2 and the position information of the portable terminal device 1. The in-building-boundary retention degree calculation device 23 calculates the number of distances equal to or less than the 1 st reference value D set in advance among the distances calculated by the distance calculation device 22 as the retention degree. In this example, the 1 st reference value D is set to 5 (m). The 1 st reference value D can be changed.
The retention calculation by the retention calculation device 23 in the building boundary calculates the number of distances equal to or less than the 1 st reference value D in a unit time for retention calculation set in advance as the retention. The retention calculation unit time is longer than the distance calculation unit time. In this example, the retention degree calculation unit time is set to 30 minutes. The retention calculation unit time can be changed. Further, the in-building-boundary retention degree calculation means 23 calculates the retention degree for each of the plurality of buildings. The building boundary inside-retention calculation device 23 calculates the retention in unit time in accordance with the distance calculation. The in-building-boundary retention degree calculation device 23 is not limited to calculating the retention degree for each unit time for distance calculation, and may calculate the retention degree for each other time.
The access destination determination device 24 determines a building that the visitor has accessed from among the plurality of buildings, using the retention degrees associated with the respective buildings. Specifically, the access destination determination device 24 determines the building with the largest retention degree among the buildings as the building that the visitor has accessed.
All the access destination information is stored in the access destination information storage device 25. The total access destination information includes information on all buildings that are likely to be accessed, information on buildings scheduled to be accessed on the current day, and the like. As all buildings that may be accessed, for example, a building to which a maintenance contract is entered may be cited. The information of the building visited on the scheduled day includes information for specifying the visitor, information at the scheduled visit time, and information for staying for the scheduled time.
The access destination determination device 24 determines the building that the visitor has accessed, using the retention and all the access destination information. When the retention degrees of the plurality of buildings are the same, the access destination determination device 24 determines the building that the visitor has accessed using the information of the building that is scheduled to be accessed on the current day. When the retention degree is equal to or less than the 2 nd reference value set in advance, the access destination determination device 24 excludes the building corresponding to the retention degree from the plurality of buildings and determines the building that the visitor has accessed. In this example, the 2 nd reference value is set to 4.
Fig. 4 is a diagram showing a building that the visitor has visited, which is determined by the visit destination determination system of fig. 1. In the display device 26, buildings to be visited are shown for a plurality of visitors, respectively. In fig. 4, the buildings visited are shown for visitor a and visitor B, respectively.
Next, a method for the visitor destination determination system to determine the building visited by the visitor will be described. Fig. 5 is a flowchart showing an operation of the access destination determination system of fig. 1. First, in step S101, a position information acquisition step is performed. In the position information acquisition step, the portable terminal device 1 acquires its own position information using signals received from GPS satellites. The position information acquisition step is performed in units of time for distance calculation.
Then, in step S102, a distance calculation step is performed. In the distance calculation step, the distance calculation device 22 calculates, for each of the plurality of buildings, a distance between the building boundary coordinates of the building and the position information of the portable terminal device 1. The distance calculating step is performed in units of time for distance calculation.
Then, in step S103, a building boundary retention degree calculation step is performed. In the building boundary retention degree calculation step, the building boundary retention degree calculation device 23 calculates, as the retention degrees, the number of distances equal to or less than the 1 st reference value D among the distances calculated in units of time for the retention degree calculation for each of the plurality of buildings. And a step of calculating the retention in the building boundary in unit time for calculating the distance.
Then, in step S104, an access destination determination step is performed. In the access destination determination step, the access destination determination device 24 determines the building that the visitor has accessed, using the calculated retention, the 2 nd reference value, and all the access destination information. As described above, the determination of the building that the visitor has visited by the visiting destination determination system is ended.
As described above, according to the access destination determination system according to embodiment 1 of the present invention, the distances between the building boundary coordinates of the building and the position information of the mobile terminal device 1 are calculated for each of the plurality of buildings for each of the distance calculation unit times, and the number of distances of 1 st reference value D or less among the calculated distances in the retention calculation unit time is calculated as the retention. Thus, even when the portable terminal device 1 cannot accurately acquire the own position information because the visitor is present in the building, the access destination determination device 24 can determine the building visited by the visitor. As a result, the visiting destination determination system can determine the building visited by the visitor more accurately.
Further, the access destination determination device 24 determines the building that the visitor has accessed, using the information of all buildings that may be accessed and the calculated retention. This can suppress the building that is unlikely to be accessed from being erroneously determined as a building that the visitor has accessed.
When the calculated retention degree is equal to or less than the 2 nd reference value, the access destination determination device 24 excludes the building corresponding to the retention degree from the plurality of buildings, and determines the building that the visitor has accessed. This makes it possible to easily perform the determination by the access destination determination device 24.
Further, according to the access destination determining method of embodiment 1 of the present invention, for each of a plurality of buildings, the distance between the building boundary coordinates of the building and the position information of the mobile terminal device 1 is calculated for each of the distance calculation unit times, and the number of distances of 1 st reference value D or less among the calculated distances in the retention calculation unit time is calculated as the retention. Thus, even when the portable terminal device 1 cannot accurately acquire the own position information because the visitor is present in the building, the access destination determination device 24 can determine the building visited by the visitor. As a result, the visiting destination determination system can determine the building visited by the visitor more accurately.
In addition, in embodiment 1 described above, the configuration in which the in-building-boundary retention degree calculation device 23 calculates the retention degree using the distance calculated by the distance calculation device 22 has been described. In contrast, the access destination determination system may further include a building inside/outside determination device that determines whether or not the mobile terminal device 1 is located in a building. In this case, the in-building-boundary retention degree calculation device 23 calculates the retention degree using the distance calculated by the distance calculation device 22 when the in-building/out determination device determines that the portable terminal device 1 is located in the building. Examples of the building interior/exterior determination device include the following: the mobile terminal device 1 can receive a signal from a GPS satellite and a signal from a base station, and when the mobile terminal device 1 can acquire position information using only the signal from the GPS satellite, it is determined that the mobile terminal device is located outside a building, and when the mobile terminal device is not located inside the building. Further, as the building interior/exterior determination device, for example, the following structures can be given: when the position information of the mobile terminal device 1 is located on a road and moves along the road, it is determined that the position information is located outside the building, and when the position information of the mobile terminal device 1 moves at a high speed, it is determined that the position information is located outside the building.
