  When the communication unit 111 receives information from the in-vehicle device 130, the control unit 112 updates the information stored in the storage unit 113 with the received information. Further, for example, when the in-vehicle device 130 is detected within the communication range of the server device 110 in the communication unit 111, the control unit 112 may transmit an information transmission request to the in-vehicle device 130 via the communication unit 111. it can.

  The storage unit 113 stores various information such as information input from the input unit 114 and information received from the in-vehicle device 130 by the communication unit 111. The information stored in the storage unit 113 is updated by the control unit 112 as described above.

  The input unit 114 includes various media drives and a keyboard for an administrator of the system to input information. The input unit 114 is used to input initial information to the storage unit 113 (for example, information that does not change over time, such as information related to the position of the roadside device), or is changed to information input as initial information. It is used to input information changes when there is an error.

  The roadside device 120 is installed, for example, on a utility pole along the road, in a store, a bus stop, a station, etc., and collects information at each installed point. The roadside device 120 transmits the collected information to the in-vehicle device 130 through communication with the in-vehicle device 130. The roadside device 120 includes a communication unit (roadside communication unit) 121, a control unit (roadside control unit) 122, a storage unit (roadside storage unit) 123, and an information collection unit 125. The communication unit 121, the storage unit 123, and the information collection unit 125 are connected to the control unit 122. Each roadside device 120 has a unique point ID. The point ID can be an arbitrary code. Hereinafter, the point ID will be described as an example of a four-digit number unique to each point.

  The communication unit 121 has a wireless access point function. That is, the communication unit 121 enables connection with the in-vehicle device 130 and enables data communication with the connected in-vehicle device 130. The specific data communication method differs depending on whether or not a wireless connection can be established between the roadside device 120 and the in-vehicle device 130, and details will be described in the description of FIG. 4 to be described later.

  The information collection unit 125 collects various types of information at the point where the roadside device 120 is installed. The information collecting unit 125 is, for example, a thermometer, a camera, or the like, and collects information related to temperature and information related to traffic volume at a point where the roadside device 120 is installed. The information collection unit 125 continues to acquire real-time information about the installed location.

  The storage unit 123 stores various information such as information collected by the information collection unit 125. In FIG. 2, the example of the information which the memory | storage part 123 of the roadside apparatus 120 memorize | stores is shown typically. As illustrated in FIG. 2, the storage unit 123 stores, for example, a spot ID, position information, content, status, and status history. As the point ID, FIG. 2 shows a four-digit number “0001” as an example.

  The position information indicates the position where this information is collected. In the present embodiment, the position information stored in the storage unit 123 also indicates the position of the roadside device. The position information can be, for example, longitude and latitude as shown in FIG. FIG. 2 shows that information was collected at a latitude of 35 degrees 39 minutes 17 seconds north and 139 degrees 44 minutes 40 seconds east longitude. In FIG. 2, the position information indicates one point, but the position information is not limited to this, and may indicate, for example, a range in which information is acquired.

  The content is specific information collected by the information collecting unit 125, and is stored in an arbitrary format such as an HTML format, a text data format, an image data format, and a video data format. The status indicates a code corresponding to the latest date and time when the storage unit 123 is updated, and the status history indicates the date and time when information related to the content is updated in association with the status corresponding to each update. When the information stored as the content is updated, the status is incremented, and the incremented status is stored in the status history together with the updated date and time. For example, referring to FIG. 2, the content was updated at 12:20 on May 21, 2013, and the status indicating this update is “1”. The content was updated at 12:23 on May 21, 2013, and the status indicating this update is “2”.

  The control unit 122 controls and manages the entire roadside device 120. When the information collection unit 125 newly collects information, the control unit 122 updates the information stored in the storage unit 123 with new information.

  Further, when the information in the storage unit 123 is updated, the control unit 122 updates an SSID (Service Set Identifier) that is an identifier of the wireless access point of the communication unit 121. The SSID includes, for example, a prefix character string, a point ID, and a status. The prefix character string is an arbitrary character string that is set in order to identify a predetermined service provided by the SSID and is unified within the system. For example, the prefix character string can be set to “BusLBS”, “LocalService”, or the like for the system according to the present invention. For example, when the prefix character string is “BusLBS” and the status is updated to “2” as shown in FIG. 2, the control unit 122 sets the SSID to “BusLBS-0001-2”. Update. The SSID is transmitted from the communication unit 121 as a beacon issued to notify the presence of the roadside device 120 as an access point.

  The in-vehicle device 130 is installed in each vehicle such as a bus or taxi, for example. The in-vehicle device 130 communicates with the server device 110 to exchange information held by each other. Further, when the in-vehicle device 130 is close to the roadside device 120 and connected to the roadside device 120, the in-vehicle device 130 acquires information transmitted by the connected roadside device 120. The in-vehicle device 130 transmits the stored information to the terminal device 140. The in-vehicle device 130 includes a communication unit (in-vehicle communication unit) 131, a control unit (in-vehicle control unit) 132, a storage unit (in-vehicle storage unit) 133, and a position detection unit 136. The communication unit 131, the storage unit 133, and the position detection unit 136 are connected to the control unit 132.

  The communication unit 131 has a wireless client function and a wireless access point function. As a function of the wireless client, the communication unit 131 connects to the server device 110 and the roadside device 120 and receives information transmitted from the server device 110 and the roadside device 120. As a function of the wireless access point, the communication unit 131 is connected to the server device 110 and the terminal device 140 and transmits information stored in the storage unit 133 by the in-vehicle device.

  The storage unit 133 stores various types of information such as information received by the communication unit 131. Each vehicle including the in-vehicle device 130 moves, and each in-vehicle device 130 is connected to the plurality of roadside devices 120 in order, and each storage device 133 acquires the respective information from each of the roadside devices 120. Information possessed by each of the plurality of connected roadside devices 120 can be stored.

  The position detection unit 135 detects the position of the in-vehicle device 130 using, for example, GPS. The position detected by the position detector 135 can be used to select information transmitted from the in-vehicle device to the terminal device 140, as will be described later.

  The control unit 132 controls and manages the entire in-vehicle device 130. The control unit 132 updates the information stored in the storage unit 133 with the information received by the communication unit 131. When the communication unit 131 receives information from the server device 110, the control unit 132 updates the information stored in the storage unit 133 with the received information. For example, in the communication unit 131, when the server device 110 is detected within the communication range of the in-vehicle device 130, the control unit 132 may transmit an information transmission request to the server device 110 via the communication unit 131. it can.

  Specifically, when the in-vehicle device 130 detects the SSID of the roadside device 120 by the communication unit 131, the control unit 132 first confirms the spot ID and the status included in the SSID. Then, the control unit 132 updates the status and status history of the information stored in the storage unit 133 corresponding to the confirmed spot ID. In addition, when the wireless LAN connection is established between the roadside device 120 and the in-vehicle device 130, the control unit 132 is a status history transmitted from the roadside device 120 acquired by the in-vehicle device 130 through the communication unit 131. The status history stored in the storage unit 133 is updated.

  Moreover, the control part 132 determines the information and method which are transmitted to the terminal device 140 to which the in-vehicle device 130 is connected. For example, the control unit 132 can determine to transmit information desired by the user based on the user's input (Pull type). Specifically, when the terminal device 140 is connected to the in-vehicle device 130, the in-vehicle device 130 transmits a distribution information list that can be distributed from the in-vehicle device 130 to the terminal device 140. The terminal device 140 that has received the distribution information list displays the distribution information list on the information display unit 147. The user selects information desired to be acquired from the displayed distribution information list and inputs it to the input unit 144 of the terminal device 140. Then, the terminal device 140 transmits an information transmission request to the in-vehicle device 130 based on the user input. When the in-vehicle device 130 receives the information transmission request, the control unit 132 determines information to be transmitted to the terminal device 140 based on the request.

  For example, the control unit 132 can determine information to be transmitted to the terminal device 140 based on the position detected by the position detection unit 136 (Push type). Specifically, the control unit 132 acquires the current position of the in-vehicle device 130 from the position detection unit 136 and determines information corresponding to the acquired position as information to be transmitted to the terminal device 140. The information corresponding to the position may be information within a predetermined range from the detected position of the in-vehicle device 130, for example. In this case, when in-vehicle device 130 and terminal device 140 are connected, in-vehicle device 130 can automatically transmit information to terminal device 140 without receiving a request from terminal device 140.

  The terminal device 140 is a communication device owned by each user, and is, for example, a mobile phone or a smartphone. The terminal device 140 may be a car navigation system installed in a car owned by the user. The terminal device 140 receives information from the in-vehicle device 130. The terminal device 140 includes a communication unit (terminal communication unit) 141, a control unit (terminal control unit) 142, an input unit 144, and an information display unit 147. The communication unit 141, the input unit 144, and the information display unit 147 are connected to the control unit 142.

  The communication unit 141 has a wireless client function. That is, the communication unit 141 is connected to the in-vehicle device 130 operating as a wireless access point as a wireless client, and receives information from the connected in-vehicle device 130.

  The input unit 144 is used for input from the user to the terminal device 140, and the information display unit 147 is used for output of various types of information from the terminal device 140 to the user. For example, when the terminal device 140 is a mobile phone, the input unit 144 is an operation key, and the information display unit 147 is a display. Further, when the terminal device 140 is a smartphone, for example, the input unit 144 and the information display unit 147 may be configured as one display.

  The control unit 142 controls and manages the entire terminal device 140. The control unit 142 establishes a wireless connection between the in-vehicle device 130 and the terminal device 140. Specifically, for example, an application for authenticating the SSID of the in-vehicle device 130 is installed in the terminal device 140 in advance, and the application authenticates that the SSID received by the communication unit 141 is the SSID of the in-vehicle device 130. In this case, the connection between the in-vehicle device 130 and the terminal device 140 is established.

  Next, an example of a series of information collection and delivery procedures in this system will be described with reference to FIG. FIG. 3 is a sequence diagram illustrating an example of a series of information collection and delivery procedures in the information collection and delivery system. In the following description of the procedure, it is assumed that the in-vehicle device 130 is installed in a route bus, and the road-side device 120 is installed on a utility pole on the route bus. In addition, information transmission from the in-vehicle device 130 to the terminal device 140 is performed in the push type. A wireless access point is disposed at the bus terminal, and the in-vehicle device 130 is configured to transmit an information transmission request to the server device 110 when the communication unit 131 detects the server device 110 within the communication range. And

  First, each roadside device 120 collects information at the installed location in the information collecting unit 125, and updates the information stored in the storage unit 123 with the collected information (step S301). In addition, the roadside device 120 updates the SSID of the roadside device 120 in the control unit 122 (step S302). Each roadside device 120 continues to acquire real-time information at the location of the roadside device by repeating steps S301 and S302. Here, as described in FIG. 2, it is assumed that the roadside device 120 updates the SSID to “BusLBS-0001-2”.

  Next, when the route bus including the in-vehicle device 130 travels near the utility pole including the road-side device 120, the road-side device 120 transmits information to the in-vehicle device 130 (step S303). The roadside device transmits information in two ways. The first method is a method of transmitting information stored in the storage unit 123 to the in-vehicle device 130 by wireless communication. In this method, the roadside device 120 transmits all or part of the information stored in the storage unit 123. The second method is a method of transmitting the SSID “BusLBS-0001-2” updated by the roadside device using a beacon.

  When the wireless LAN connection is established between the roadside device 120 and the in-vehicle device 130, the in-vehicle device 130 can receive information transmitted by the roadside information by the first method. However, for example, when the in-vehicle device 130 is moving at a high speed, there is a case where a wireless LAN connection cannot be established. In this case, the in-vehicle device 130 cannot receive information transmitted by the roadside device by the first method.

  Even in such a case, as illustrated in FIG. 4A, the in-vehicle device 130 can receive the SSID “BusLBS-0001-2” transmitted by the roadside device 120 by the second method. The in-vehicle device 130 can know the latest status updated in the roadside device by checking the SSID. If the status of the received SSID in the control unit 132 is the same as the status stored in the storage unit 133, the in-vehicle device 130 has no change in the information that the roadside device 120 has, and the information that the storage unit 133 has. Is still up to date. On the other hand, when the status of the received SSID is different from the status stored in the storage unit 133, the in-vehicle device 130 recognizes that the status is different as a result of the information being updated in the roadside device 120. be able to. When the statuses are different, the in-vehicle device 130 decelerates from the roadside device 120 via the communication unit 131 when wireless communication with the roadside device 120 becomes possible as shown in FIG. Information can be received by one method. In this way, the in-vehicle device 130 acquires the latest information that the roadside device 120 has, that is, real-time information.

  FIG. 5 is a diagram illustrating communication between the roadside device and the in-vehicle device. The roadside device 120 preferably transmits all the latest information and history information to the in-vehicle device 130. However, even if the wireless LAN connection cannot be established between the roadside device 120 and the in-vehicle device 130 and information cannot be transmitted through the wireless LAN connection, the in-vehicle device 130 confirms the status by the second method. can do.

  Referring to FIG. 3 again, the in-vehicle device 130 that has received the information from the roadside device 120 updates the information stored in the storage unit 133 with the received information (step S304). The in-vehicle device 130 repeats steps S303 and S304 while the bus including the in-vehicle device 130 circulates the route, and updates the information stored in the storage unit 133 with the information that each roadside device 120 has.

  Then, when the route bus returns to the bus terminal and the in-vehicle device 130 is connected to the server device 110 via the wireless access point, the in-vehicle device 130 transmits an information transmission request to the server device 110 (step S305). As a response to the information transmission request, the server device transmits information stored in the storage unit 113 to the in-vehicle device 130 (step S306). The in-vehicle device 130 that has received the information updates the information stored in the storage unit 133 with the received information (step S307). The in-vehicle device 130 that has received the information transmits the information collected from each roadside device 120 and stored in the storage unit 133 by patrol to the server device 110 (step S308). The server apparatus 110 that has received the information updates the information stored in the storage unit 113 with the received information (step S309). In this way, by transmitting information from the server device 110 that has received the information of each in-vehicle device 130 to the in-vehicle device 130, the in-vehicle device 130 receives information at a point where the information is not collected because it has not passed. be able to. Moreover, the server apparatus 110 can update the information which the server apparatus 110 has to real-time information by receiving information from the in-vehicle apparatus 130 which collected the real-time information of each roadside apparatus 120.

  FIG. 6 is a diagram illustrating communication between the server device and the in-vehicle device. Through steps S <b> 305 to S <b> 309, the server apparatus 110 and the in-vehicle apparatus 130 update information held by each other.

  Refer to FIG. 3 again. Subsequently, it is assumed that the user having the terminal device 140 gets on the bus while the route bus is traveling around the route. Then, it is assumed that communication is established between the in-vehicle device 130 and the terminal device 140. At this time, the in-vehicle device 130 detects the position of the in-vehicle device 130 in the position detection unit 136 (step S310). And the in-vehicle apparatus 130 transmits the information corresponding to the detected position among the information memorize | stored in the memory | storage part 133 to the terminal device 140 (step S311). Then, the terminal device 140 displays the received information on the information display unit 147 (step S312).

  FIG. 7 is a diagram illustrating communication between the in-vehicle device and the terminal device. The user can acquire information according to the position of the bus including the in-vehicle device 130 by confirming the display on the information display unit 147. In this manner, the in-vehicle device 130 detects its own position and transmits information corresponding to the position to the terminal device 140, for example, for a user of the terminal device 140 that does not have a function of detecting the current position. It becomes possible to provide information according to the position.

  As described above, according to the present embodiment, the in-vehicle device 130 acquires the real-time information collected by each roadside device 120 and shares it with the server device 110, so that the information that the server device 110 has is real-time. Updated as needed. Moreover, the in-vehicle device 130 can acquire real-time information at each point by receiving information from the server device 110 without receiving information directly from the roadside device 120 itself. By sharing information between the server device 110 and the in-vehicle device 130, the information provided from the in-vehicle device 130 to the terminal device 140 becomes real-time information at the location of each roadside device 120. Can be distributed to users.

(Second Embodiment)
FIG. 8 is a system configuration diagram of an information collection and delivery system according to the second embodiment of the present invention. In the information collection / delivery system in this embodiment, in addition to the in-vehicle device, the terminal device also plays a role of information collection / delivery. Hereinafter, description of the same points as in the first embodiment will be omitted, and different points will be described.
