<First embodiment>
Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. The security support system 10 is a system that allows security guards to quickly go directly to the emergency situation by transmitting report information using communication terminals carried by the staff when the staff discovers and confirms an emergency situation. .

《Configuration of security support system》
FIG. 1 is a diagram showing the configuration of a security assistance system 10 according to the first embodiment. The security auxiliary system 10 includes a security auxiliary device 100, a notification storage device 11, a display device 12, and a position information communication device 13.

The notification storage device 11 is a device that receives notification information from the security auxiliary device 100 through communication and stores the notification information. For example, the notification storage device 11 may be an on-premises storage or a cloud storage.

The display device 12 is a device that receives report information from the report storage device 11 through communication and displays the report information. For example, the display device 12 may be a display device. The display device 12 may receive report information directly from the security auxiliary device 100 without going through the report storage device 11.
The location information communication device 13 is a device that provides the security auxiliary device 100 with the geographical location of the location information communication device 13 in real time using a wireless signal. For example, the location information communication device 13 may be a beacon or a communication device using a wireless LAN.

An outline of the operation of the security assistance system 10 will be described below.
The building 20 in FIG. 1 is a three-story building, and the staff 30 is on the second floor of the building 20.
There is a beacon, which is a location information communication device 13, on each floor of the building 20, and the security auxiliary device 100, which is a communication terminal, receives the geographical location, which is the current location of the security auxiliary device 100, from the location information communication device 13 on each floor in real time. get. The staff member 30 is an example of a user of the security assistance device 100.

In the event of an emergency, the staff member 30 on the second floor transmits reporting information using the security auxiliary device 100, which is a communication terminal. The report information includes location information indicating either the last geographical location acquired from the location information communication device 13, the geographic location input by the staff 30, or the fact that the current location input by the staff 30 is unknown. is included.

The report storage device 11 receives the above-mentioned report information from the security auxiliary device 100 and stores the report information together with the position information of the staff member 30.
The display device 12 receives the position information and report information stored in the report storage device 11 in real time, and displays them on the display device.

The supervisor 40 looks at the report information displayed on the display device 12 and notifies the guard communication terminal 60 carried by the guard 50 of the report information, and also informs the guard 50 of the geographical location where the staff 30 is located. Instruct them to go straight to. Here, the security assistance system 10 may directly instruct the security guard communication terminal 60 of the security guard 50 from the report storage device 11 without using the supervisor 40.

The security guard 50 travels directly to the geographic location of the staff member 30 based on the direct instruction received by the security guard communication terminal 60 carried by the security guard 50.

《Configuration of security auxiliary device》
FIG. 2 is a diagram showing the configuration of the security auxiliary device 100 according to the first embodiment. The security auxiliary device 100 includes a report input section 105, a position acquisition section 110, a determination section 115, a position input section 120, a report transmission section 130, and an automatic transmission section 160.

The report input unit 105 receives input of report instructions from the staff 30.
The position acquisition unit 110 acquires the geographical position of the security auxiliary device 100 and the time related to the geographical position in real time by receiving a wireless signal from the position information communication device 13. For example, when the security auxiliary device 100 is located outdoors, the geographical location can be expressed by longitude and latitude, and when it is located indoors (inside a building), the geographical location can be expressed by the latitude and longitude of the building, as well as the location within the building. It can be expressed by coordinates, etc.
For example, when the security auxiliary device 100 is located on the second floor of a building 20 as shown in FIG. Then, the geographical location indicating that the location is on the second floor of the building 20 is obtained. Furthermore, the location acquisition unit 110 may acquire, for example, the room number of the room where the security auxiliary device 100 is present as the geographical location.

The determining unit 115 determines whether the geographical position acquired by the position acquiring unit 110 is accurate or inaccurate. Specifically, the determination unit 115 determines that the geographical position acquired by the position acquisition unit 110 is accurate if the elapsed time from the time when the position acquisition unit 110 last acquired the geographical position is within a certain time; If the time elapsed since the last time the location acquisition unit 110 acquired the geographic location is not within a certain period of time, the geographic location is determined to be inaccurate.

Other examples of methods for the determining unit 115 to determine whether the geographical position acquired by the position acquiring unit 110 is accurate or inaccurate include the following example.
The determination unit 115 determines that the geographical position acquired by the position acquisition unit 110 is determined when the number of satellites from which the position acquisition unit 110 is receiving radio waves related to the geographical position in real time is equal to or greater than a preset threshold. It may be determined that it is accurate.
The determination unit 115 determines whether the number of positioning means from which the position acquisition unit 110 is receiving radio waves related to the geographical position in real time is equal to or greater than a preset threshold, as the geographical position acquired by the position acquisition unit 110. may be determined to be accurate. Examples of the above positioning means include beacons, GNSS, Wifi, mobile base stations, and magnetic positioning.
The determining unit 115 determines that the geographical position acquired by the position acquiring unit 110 is accurate when the number of beacons receiving radio waves related to the geographical position in real time is equal to or greater than a preset threshold. Also good.

Furthermore, the determination unit 115 may make a determination using the above example in conjunction with the user's settings and the environment identified by the security auxiliary device 100.
For example, when the security auxiliary device 100 is located outdoors, the determination unit 115 determines that the number of satellites from which the position acquisition unit 110 is receiving radio waves related to the geographical position in real time is set in advance by the staff 30. The geographical position acquired by the position acquisition unit 110 may be determined to be accurate if the geographical position is equal to or greater than a threshold value. On the other hand, when the security auxiliary device 100 exists indoors, the determination unit 115 determines that the number of beacons from which the position acquisition unit 110 receives radio waves related to the geographical position in real time is set in advance according to the settings of the staff 30. The geographical position acquired by the position acquisition unit 110 may be determined to be accurate if the geographical position is equal to or greater than a threshold value.

According to the above example, even if the position acquisition unit 110 is able to acquire position information in real time, for example, outdoors, the number of satellites from which GNSS information can be acquired is small, the wireless LAN used in conjunction with GNSS, or the mobile base. Even if radio waves cannot be received from a station or the like, or if there are too many communication devices indoors, the geographical position acquired by the position acquisition unit 110 can be determined to be inaccurate, depending on the user's settings. Thereby, the security guard 50 can reduce time loss due to reports related to geographical locations that are significantly different from the current location.

When the determining unit 115 determines that the geographical position acquired by the position acquiring unit 110 is inaccurate, the position input unit 120 receives information from the staff 30 about the current position of the staff 30 or the staff 30's geographical position. A screen for receiving input position information indicating that the current position is unknown is displayed, and the input position information is received from the staff member 30. An example of the screen is a screen provided in the security auxiliary device 100. Further, as an example of the display mode of the screen, if the determining unit 115 determines that the geographical position acquired by the position acquiring unit 110 is inaccurate, it is grayed out and input is not possible until the determination is made. For example, the map or checkbox on the screen that was previously displayed is activated and becomes available for input.

The report transmitter 130 transmits report information including location information to the security support system 10 based on the report instruction. Specifically, when the report input unit 105 receives a report instruction, if it is determined that the geographical position acquired by the position acquisition unit 110 is accurate, the report transmission unit 130 transmits the geographical position. It is transmitted to the notification storage device 11 of the security support system 10, which is a system related to security.
In addition, when the report input unit 105 receives a report instruction, if it is determined that the geographical position acquired by the position acquisition unit 110 is inaccurate, the report transmission unit 130 transmits the position input unit 120 to the staff member 30. The above-mentioned input position information inputted from is transmitted to the notification storage device 11.

For example, it is assumed that the fixed time period for the determination by the determination unit 115 described above is 5 minutes. If the time when the position acquisition unit 110 last acquired the geographical position is within 5 minutes from the time when the report input unit 105 received the report instruction, the determination unit 115 determines that the geographical position is accurate. The report transmitter 130 transmits the geographical location to the report storage device 11. Further, if the time when the position acquisition unit 110 last acquired the geographical position is not within 5 minutes from the time when the report input unit 105 received the report instruction, the determination unit 115 determines that the geographical position is inaccurate. In order to do so, the report transmitting unit 130 transmits the input position information inputted by the position input unit 120 from the staff member 30 to the report storage device 11 .
Further, for example, if the current location of the security auxiliary device 100 is indoors but the location information communication device 13 cannot be installed and the location information of the security auxiliary device 100 cannot be acquired, the above-mentioned fixed time may be set to 0 minutes. In this case, when the report input unit 105 receives a report instruction, the report transmitter 130 always transmits the input position information input by the position input unit 120 from the staff 30 to the report storage device 11. .

When the report transmitter 130 transmits input location information indicating that the current location is unknown to the report storage device 11, the automatic transmitter 160 transmits a call to a preset contact and sends a call to the contact and security assistance. A conversation with the device 100 is started. As an example of the automatic transmission unit 160, when the notification transmission unit 130 transmits input position information indicating that the current location is unknown to the notification storage device 11, the automatic transmission unit 160 transmits the input position information to the monitoring person 40 set in advance, and 40 and the staff 30 to start a telephone conversation.
Furthermore, the automatic transmission unit 160 may display an image shooting screen before making the above-mentioned call, and may transmit the image taken by the staff member 30 to the destination of the call together with the above-mentioned call.

《Operation of security auxiliary device》
Next, the operation of the security auxiliary device 100 will be explained.
FIG. 3 is a flowchart showing the operation of the security auxiliary device 100.

The report input unit 105 receives input of a report instruction from the staff 30 (step S11).
After step S11, the report transmitting unit 130 determines whether the geographical position of the security auxiliary device 100 acquired by the position acquiring unit 110 is accurate or inaccurate (step S12).
When the geographical position acquired by the position acquisition unit 110 is accurate (step S12: accurate), the notification transmitting unit 130 transmits the geographical position to the notification storage device 11 (step S13).

If the geographic location acquired by the location acquisition unit 110 is inaccurate (step S12: inaccurate), the location input unit 120 displays a screen on which the staff 30 can input location information (step S14). An example of this screen is a screen that simultaneously displays a checkbox that allows you to select that your current location is unknown and a map that allows you to tap your current location. The staff member 30 can select the current location by tapping the screen on which the map is displayed.
In addition, on the screen in step S14, a map on which the staff 30 can tap the current location is first displayed, and only if there is no tap by the staff 30 within a certain period of time after the map is displayed on the screen, the current location is unknown. You may decide that this is the case and report it.

When the staff member 30 taps the current location on the map (step S15: NO), the notification transmitter 130 transmits input position information regarding the current location to the notification storage device 11 (step S16). On the other hand, if the staff member 30 selects the checkbox indicating that the current location is unknown (step S15: YES), the notification transmitter 130 stores the input location information indicating that the current location is unknown in the notification storage device 11. (step S17).

After step S17, the automatic calling unit 160 makes a call to the preset contact information of the supervisor 40 (step S18), and starts a conversation between the staff 30 and the supervisor 40 (step S19).
