  Hereinafter, a location management system to which the present invention is applied will be described with reference to the drawings showing an example of an embodiment to which the present invention is applied.

  FIG. 1 is a configuration diagram schematically showing an example of the configuration of a location management system to which the present invention is applied. Here, “location management” means management of information on a position, that is, a point where the user has moved and acted.

  In FIG. 1, reference numerals 1, 2, 3, and 4 indicate main elements constituting the mobile terminal 100, and reference numerals 5, 6, 7, 8, 9, and 10 indicate main elements that configure the server device 200. Indicates.

  The mobile terminal 100 is possessed by a user who is an object of location management by this system. The mobile terminal 100 is, for example, a car navigation device mounted on a vehicle, a smartphone or a tablet terminal with a built-in GPS device, or the like. The mobile terminal 100 includes a processing device 1 including a memory such as a microprocessor, DRAM, and SRAM, a sensor device 2 including a vehicle speed sensor, a gyroscope, and a GPS receiver, and data acquired from the sensor device 2. An external storage medium 3 that stores position information determined by the processing device 1 based on the interface, and an interface for transmitting the position information stored in the external storage medium 3 to the server device 200 via a communication network such as the Internet or a LAN. And a communication device 4 such as a mobile phone.

  Each function of the mobile terminal 100 is realized by the microprocessor of the processing device 1 reading a predetermined program stored in the external storage medium 3 into the memory and executing it.

  The server device 200 is connected as a processing device 5 including a memory such as a microprocessor, a DRAM, and an SRAM, and an interface for connecting to a communication network such as the Internet or a LAN so as to receive position information from the mobile terminal 100. The device 6, the storage device 7 for storing the position information sent from the mobile terminal 100, and recording / saving the stay point information, the destination point information and the action point information, and the user An input device 8 for inputting daily reports, a display device 9 for displaying position information, destination point information and action point information, diaries, daily reports and the like sent from the mobile terminal 100, and diaries and daily reports. And a printing apparatus 10 that outputs a form.

  Each function of the server device 200 is realized by the microprocessor of the processing device 5 reading a predetermined program stored in the storage device 7 and executing it.

  FIG. 2 is a diagram illustrating an example of a data configuration of position information stored in the external storage medium 3 of the mobile terminal 100 and the storage device 7 of the server device 200. The position information is stored in the external storage medium 3 of the mobile terminal 100 during operation of the system, transmitted to the server device 200 via the communication network, and stored in the storage device 7. As position information, data of “positioning date / time”, “latitude”, and “longitude” are stored in one record. The positioning date and time is the date and time when position detection is performed by the sensor device 2. The time interval for recording the position information is arbitrary, but a time interval of several seconds to several tens of seconds is desirable.

  FIG. 3 is a diagram illustrating an example of a data configuration of the stay point information stored in the storage device 7 of the server device 200. The stay point information is derived by the processing device 6 of the server device 200 based on the stored location information record shown in FIG. This deriving process of stay point information is performed after collecting location information collected for a certain period, such as daily batch processing. As stay point information, data of “stay start date / time”, “stay point latitude”, and “stay point longitude” are stored in one record.

  The stay point information is derived as follows. The time interval calculated from the difference between the “positioning date / time” of two consecutive records (for example, the position information # 0 and the position information # 1) in the plurality of position information shown in FIG. 2, the “latitude” and the “longitude” Using the distance calculated from the difference, the moving speed between two points corresponding to two consecutive pieces of position information can be calculated. This moving speed is calculated for each set of two consecutive records in the plurality of position information. When the distance calculated from the two records is “0”, the moving speed is also “0”. Next, in the time series of the calculated movement speed, a time zone in which the movement speed is “0” is detected.

  Here, when no movement occurs, the condition is that the movement speed is “0”. However, instead of this condition, the movement speed may be a predetermined minimum speed or less. This condition determines that the movement is not substantially performed even for a very slow movement or movement within a limited range. The condition that the moving speed is “0” is also one of the conditions that the moving speed is equal to or less than a predetermined minimum speed.

  Further, a time period in which the detected time period during which the state of the movement speed “0” is maintained is equal to or greater than a predetermined minimum time period is extracted. When such a time zone is extracted, it is determined that the user stayed at substantially the same position during that time zone, and one record of stay point information is stored. At that time, “positioning date / time” of the first location information in that time zone is set as “stay start date / time”, and “latitude” and “longitude” of the first location information are “stay location latitude” and “stay location longitude”, respectively. To do. For example, when the time interval for recording position information is 10 seconds and the minimum time length is 15 minutes, when the moving speed “0” calculated from two consecutive records of position information continues 90 times or more, Save one record of stay point information.

  As described above, the stay point information is derived by extracting a time zone of a predetermined length or more without substantial movement based on the positioning date, latitude, and longitude of each of the plurality of position information.

  FIG. 4 is a diagram illustrating an example of a data configuration of destination point information stored in the storage device 7 of the server device 200. The destination point information is stored in advance in the storage device 7 prior to actual operation of the system. The user inputs the destination point information from the input device 8 of the server device 200. As destination point information, data of “target point name”, “destination point address”, “destination point longitude”, “destination point latitude”, and “standard event” are stored in one record.

  Destination information includes the “destination name” and “destination address” indicating the location of the place where the user often stays or visits regularly in the daily activities of the user, and the “destination point” indicating the position. Save "Longitude" and "Destination Latitude". Further, when there is an event that is routinely performed at the place, a “standard event” indicating the event is stored.

  As another example of the registration form of the destination point information, the user of the mobile terminal 100 may be configured to transmit and register from the mobile terminal 100 to the server device 200.

  FIG. 5 is a diagram illustrating an example of a data configuration of action point information stored in the storage device 7 of the server device 200. The action point information is derived by the processing device 6 of the server device 200 based on the stay point information shown in FIG. 3 and the destination point information shown in FIG. This action point information derivation process may be performed subsequent to the stay point information derivation process of FIG. As action point information, data of “action date / time”, “action point name”, “action point address”, “action point longitude”, “action point latitude”, and “standard event” are stored in one record.

  The action point information is derived as follows. The destination point information of FIG. 4 is referred to based on the latitude and longitude of the stay point information of one record of FIG. More specifically, the destination point information having the destination point latitude and the destination point longitude included within the radius of 100 m, for example, is searched and extracted with the stay point as the center. If one or more destination point information is extracted, action point information is preserve | saved in the memory | storage device 7 based on stay point information and each destination point information. At that time, “stay start date / time” of the stay point information is set as “action date / time” of the action point information, and “destination name”, “destination address”, “destination longitude”, “destination latitude” of the destination point information. , “Standard event” is “action point name”, “action point address”, “action point longitude”, “action point latitude”, and “standard event” of the action point information. Therefore, one or a plurality of action point information may be derived as candidates from the stay point information of one record and stored, but appropriate action point information (points actually performed by the user) among those candidates. Is selected by the user (see step 109 in FIG. 6 described later).

  FIG. 6 is a flowchart showing an example of a processing procedure of the location management system shown in FIG.

  First, prior to system operation, the user inputs destination point information in advance from the input device 8 of the server device 200 (step 101), and the server device 200 registers the destination point information shown in FIG. (Step 102).

  When the system is in operation, the mobile terminal 100 stores and accumulates the mobile terminal user location information acquired by the sensor device 2 and the processing device 1 in the external storage medium 3 (step 103).

  The location information stored in the external storage medium 3 is transmitted from the communication device 4 of the mobile terminal 100 to the communication device 5 of the server device 200 via the communication network (step 104). The movement information is transmitted periodically, for example, daily batches. Usually, a certain amount of position information is accumulated at the time of transmission.

  The server device 200 receives the position information and stores it in the storage device 7 (step 105). Next, a process for deriving the stay point information based on the position information stored in the storage device 7 is performed, and the derived stay point information is stored in the storage device 7 (step 106). The process for deriving the stay point information is as described in FIG.

  Further, the server device 200 performs processing for deriving the action point information based on the stay point information and the destination point information, and stores the derived action point information in the storage device 7 (step 107). The processing to be performed is as described in FIG. The process for deriving the action point information is periodically performed, for example, daily batch.

  If a plurality of action point information is obtained, the information is sorted in time series based on the “action date and time”, and the result is displayed on the display device 9 (step 108). By displaying the action point name and the like, the user can surely recall the memory of his / her action. The displayed action point information is base data for the user to create a diary, daily report, and the like. For example, the action date and time, the action spot name, the action spot address, or the contents of the routine event can be copied and used as they are in a diary or daily report. The user confirms the diary, daily report, etc. on the display device 9 using the displayed action point information as base data, corrects it, etc., and completes it (step 109). In that case, although a plurality of action point information candidates may be output for one action date and time, the user selects an appropriate one (actually performed point). When the diary, daily report, etc. are completed, the printing apparatus 10 appropriately prints and outputs a form (step 110).
