Description

  The present invention relates to an information collection / delivery system, an information collection / delivery server, an information collection / delivery method, and an information collection / delivery program for collecting and delivering information indicating that a facility has been used by a mobile object.

  In recent years, with the spread of mobile terminals such as smartphones, it has become possible to easily acquire various information while on the go. Especially when traveling by car etc., the map service provided as a network service makes it easy to know the location of facilities that are planned to be used when moving, such as stores and gas stations in the direction of travel. It is.

  For example, Non-Patent Document 1 proposes a service that can acquire information associated with an access point when a user with a smartphone goes near an access point (wireless LAN access point). This also allows the network server to know that the user is near the access point.

  On the other hand, when the communication infrastructure is not established, information cannot be acquired by the mobile terminal. On the other hand, even in a place where communication infrastructure is not established, for example, a method of installing an information distribution device on a road and distributing data in the information distribution device to nearby portable terminals is conceivable. In this method, when the information distribution apparatus is not connected to the communication infrastructure, updating the information in the apparatus becomes a problem. In response to this problem, Non-Patent Document 2 proposes an information collection method using a taxi. According to Non-Patent Document 2, a vehicle collects data on a route outside the vehicle, and the vehicle that collects data from a point connected to a network such as a sales office connects to the network to synchronize information. Is possible.

  In addition, many services that provide information corresponding to the current position to users who have mobile terminals that have gone out have appeared. For example, since a mobile terminal such as a smartphone can detect the current position using a global positioning system (GPS) or the like, it is possible to distribute information according to the current position. Information distribution according to the position for such a smartphone is realized by transmitting position information from a smartphone to a server on the Internet using a communication function and providing information corresponding to the position information received by the server. Yes.

  In addition, as a function for providing information according to position information received by a server, Patent Document 1 stores information in association with geography and time, and acquires and outputs information based on position information such as the current location. A method is described.

  In this way, even when communication infrastructure is not established, information can be widely distributed. Further, it is possible for the user to detect the current position using GPS or the like and to provide information associated with the user in advance.

  Furthermore, as a method for exchanging information from an access point, in addition to a method of acquiring information by connecting to an access point as usual, in Patent Document 2, by changing a character string of an SSID generated by a beacon signal of an access point , You can get information without connecting. As a result, it is possible to save time for connection and acquire information in a short time.

  In the fourth embodiment, the access point 50 includes facility information of a facility existing within a predetermined range from the access point 50 in a beacon signal transmitted to the outside. For example, the facility ID and the use time are assigned to the SSID included in the beacon signal. When one access point 50 emits a plurality of facility information, it can be dealt with by issuing a plurality of SSIDs from one access point 50.

  Since the SSID can arbitrarily set up to 32 single-byte alphanumeric characters, the SSID can be a combination of a facility ID of 5 digits and a usage time of 4 digits. For example, if the facility ID is 11113 and the use time is 10:26, the SSID is 1113-1026. Of course, the usage time may be 8 digits including the month and day information, but if the facilities providing the information are limited to those that were available on the same day, Even if it is only time information without putting, it can endure practical use.

  When receiving a beacon signal from the access point 50, the communication unit 32 acquires facility information from the beacon signal (SSID) and outputs the facility information to the information display unit 31. If the information collection / delivery server 10 and the facility information acquisition apparatus 30 have a correspondence table between the facility ID and the actual facility in advance, the availability of the facility can be determined from the SSID.

  According to the fourth embodiment, since the vehicle 300 only receives the beacon signal of the access point 50 when acquiring facility information, the vehicle 300 is shorter than the case of establishing a connection with the access point 50. Facility information can be acquired in time, and the risk of failing to acquire facility information can be reduced.
