<Second embodiment>
Next, a second embodiment of the present invention will be described. In the position information transmission system 1000 according to the second embodiment, the position information transmission apparatus 100 has a plurality of modes (normal mode and emergency mode), and executes predetermined processing according to each mode. Specifically, the position information transmission apparatus 100 changes the position information generation timing and the position information transmission timing in accordance with the set mode. Note that description of functional units that perform the same processing as in the above-described embodiment is omitted.

  The control unit 101 has a mode setting unit. The mode setting unit is a functional unit that sets the mode of the position information transmission device 100. Specifically, the mode setting unit sets one of a normal mode and an emergency mode. More specifically, when the mode setting unit receives an emergency signal transmitted from the vehicle system at the time of occurrence of a train accident or the like via the input reception unit 110, the mode setting unit performs emergency for a predetermined time (for example, 24 hours). Set the mode. The mode setting unit sets the normal mode when a predetermined time has elapsed.

  Further, the position information generation unit 113 generates position information at a shorter time interval (for example, every 5 seconds) than when the normal mode is set while the emergency mode is set, and the position information transmission unit 114. The IMES signal including the position information is transmitted in the vehicle via.

  According to the position information transmission apparatus 100 according to such an embodiment, a more specific place can be transmitted. In particular, the position information transmission device 100 sets an emergency mode in an emergency such as a train accident, and transmits position information to the mobile terminal 200 in the vehicle at a shorter time interval than in the normal mode. Therefore, when the user makes an emergency call, information that can identify the social location can be transmitted to the reception desk device that receives the emergency call almost certainly.

  In the above-described embodiments, the position information is transmitted to the mobile terminal 200, but the present invention is not limited to these embodiments. For example, when the emergency mode is set, the position information transmission apparatus 100 according to the modification of the second embodiment displays the position information including the physical place specifying information 120 and the social place specifying information 130, and the social place. Display information to be displayed is transmitted to the mobile terminal 200. More specifically, when the emergency mode is set by the mode setting unit, the position information generation unit 113 generates display information that displays a social place in addition to the position information, and combines them with the mobile terminal 200. Send to. The display information for displaying the social place may be character string information or image information. When the mobile terminal 200 acquires such information, information specifying a social place such as “This vehicle is a ** car” is displayed on the display.

  According to such a position information transmission device 100, the user of the mobile terminal 200 can make an emergency call after recognizing the social place where the user is. In other words, the reporter can directly communicate the social location to the person who received the emergency call.

  In the above-described embodiment, the position information transmission apparatus 100 generates position information according to the IMES message format and transmits the position information as an IMES signal in the vehicle. However, the present invention is not limited to this. . The position information transmission device 100 is positioned by wireless communication based on various wireless communication standards such as Wi-Fi, Bluetooth (registered trademark), infrared communication, visible light communication, ultrasonic communication, and communication using RFID (Radio Frequency Identification). Information may be transmitted to the mobile terminal 200. A more specific place can be transmitted also by such position information transmission apparatus 100.

  In the above-described embodiment, the GPS signal receiving unit 112 of the position information transmission apparatus 100 calculates the latitude and longitude that specify the physical location from the GPS signal, but the present invention is not limited to this. For example, the position information generation unit 113 of the position information transmission device 100 generates position information including only the social location specifying information 130. In addition, the GPS signal acquisition unit 201 of the mobile terminal 200 calculates the latitude and longitude that specify the physical location from the acquired GPS signal. In addition, the function control unit 206 of the mobile terminal 200 generates a transmission signal including the social location specifying information 130 acquired from the location information transmission device 100 and the physical location specifying information 120 calculated by itself at the time of an emergency call. This is transmitted to the reception desk device. A more specific place can be transmitted also by such position information transmission apparatus 100.

  Further, the position information transmission apparatus 100 according to the above-described embodiment generates position information at a predetermined time interval (for example, once every 60 seconds) and transmits the position information to the mobile terminal 200. It is not restricted to such an embodiment. For example, the position information transmission apparatus 100 may generate position information when a position information acquisition request signal from the mobile terminal 200 is received, and transmit the position information to the mobile terminal 200. Specifically, when the function control unit 206 of the mobile terminal 200 receives an emergency call instruction such as No. 110 from the user, the function control unit 206 generates a position information acquisition request signal and transmits it to the position information transmission device 100. A more specific place can be transmitted also by such position information transmission apparatus 100.

  Moreover, although the portable terminal 200 which concerns on above-mentioned embodiment transmitted the transmission signal containing a positional information, when the transmission instruction | indication of an emergency call was received from the user, this invention is not limited to this. For example, the position information generation unit 113 of the position information transmission device 100 generates an instruction signal including the position information and information regarding the transmission timing and transmission destination of the position information, and transmits the instruction signal to the mobile terminal 200. The portable terminal 200 transmits a predetermined timing (for example, a server device or reception desk device included in a communication carrier of the portable terminal 200) at a transmission timing (for example, once every 60 seconds) according to the instruction. Thus, identification information (for example, a telephone number or an e-mail address) of the mobile terminal 200 and position information including the social location specifying information 130 are transmitted. The location information is transmitted without transmitting a call such as an emergency call and transmitting identification information and location information.

  A more specific place can be transmitted also by such position information transmission apparatus 100. In particular, the position information transmission apparatus 100 can transmit position information from the portable terminal 200 to a predetermined location at a predetermined timing. Therefore, even in a situation where the user of the mobile terminal 200 cannot make an emergency call (for example, when injured due to a train accident or the like), the communication carrier or reception desk identifies the social location where the user is located. be able to.
