In the present embodiment, the receiving device 12 accumulates passing information each time it becomes communicable with the transmitting / receiving device 10. Further, in the present embodiment, the receiving device 12 encrypts and records the passing information for each identification information. The process of step A5 may be executed before the process of step A4, or the process of step A4 and the process of step A5 may be executed at the same time.

Next, as described above, the information collecting device 14 collects the transmission / reception device passing information and the passing information recorded in each receiving device 12 (step A6). In the present embodiment, when the distance between the receiving device 12 and the information collecting device 14 is equal to or less than a predetermined distance, the information transmitted from the receiving device 12 is acquired by the information collecting device 14.

Finally, as described above, the analyzer 16 analyzes the movement path of each moving body 50 based on the information (transmission / reception device passing information and passing information) collected by the information collecting device 14 from each receiving device 12 (the moving path of each moving body 50). Step A7).

In the present embodiment, each receiving device 12 records the transmission / reception device passing information and the passing information. Therefore, even if the plurality of receiving devices 12 and the information collecting device 14 are not connected via the network, the information collecting device 14 analyzes the moving route of the moving body 50 individually from the plurality of receiving devices 12.

Thereby, for example, it is possible to collect information for analyzing the movement route of the moving body even in an environment where a network is not constructed.

Further, in the present embodiment, the information collecting device 14 can acquire information directly from the receiving device 12 or by using short-range wireless communication. In this case, the cost of using the storage system 100 can be reduced as compared with the case where the information collecting device 14 acquires information from the receiving device 12 by using satellite communication.

The storage system 100 according to the present embodiment is, for example, a search for pets, a search for stolen objects such as bicycles, a search for missing persons, identification of a return location for bicycle rental, a location of a cart in a store such as a supermarket, or a cart. It can be used to grasp the movement line of the bicycle, the tour route of tourists in the tourist spot, the position of the climber, the climbing route of the climber, and the like. The interval between the plurality of receiving devices 12 may be appropriately set according to the purpose of use of the storage system 100 and the like. For example, a plurality of receiving devices 12 may be arranged so that the communication areas 20 of the adjacent receiving devices 12 overlap each other, or a plurality of receiving devices 12 may be arranged so that the communication areas 20 of the adjacent receiving devices 12 do not overlap each other. 12 may be arranged. Further, the storage system 100 according to the present embodiment may be used in an environment in which a network is constructed. In this case, both information collection using the network and information collection not using the network become possible, and the convenience of the storage system 100 is further improved.

[Modification example]
The transmission / reception device 10 may transmit identification information at regular intervals with a predetermined radio wave intensity. For example, the transmission / reception device 10 may include an iBeacon (registered trademark) using BLE (Bluetooth (registered trademark) Low Energy) provided by Apple Inc. In this case, the receiving unit 12a of the receiving device 12 may receive the identification information at regular time intervals and measure the received radio wave intensity when the identification information is received. Further, the recording unit 12b may further record the received radio wave intensity measured by the receiving unit 12a in addition to the identification information and the receiving time. The received radio wave intensity recorded in the recording unit 12b in each receiving device 12 is collected by the information collecting device 14 and given to the analyzer 16. The analysis unit 16d of the analyzer 16 calculates the distance between the transmitter / receiver 10 and the receiver 12 based on the received radio wave intensity recorded by each receiver 12. As a result, the analysis unit 16d can analyze the movement path of the moving body 50.

The unique information contained in the receiving device 12 is not limited to the position information shown in FIG. For example, each of the plurality of receiving devices 12 may have different identification information as unique information. In this case, the installation information storage unit 16b described above stores installation information (for example, latitude and longitude) associated with the identification information of each receiving device 12.

Further, the configuration of the storage system 100 is not limited to the above example. For example, as shown in FIG. 10, the storage system 100 may include a plurality of image pickup devices 22. In the example shown in FIG. 10, a photographing device 22 is provided for each receiving device 12. Although the image pickup device 22 is provided for each of the receiving devices 12 in FIG. 10, the image pickup device 22 may not be provided for any of the receiving devices 12.

FIG. 11 is a block diagram showing the configuration of the image pickup apparatus 22. Note that FIG. 11 shows a block diagram of the receiving device 12 in addition to the imaging device 22. In the present embodiment, the receiving device 12 further includes a shooting instruction unit 12d in addition to the above-mentioned second receiving unit 12a, the second recording unit 12b, and the output unit 12c. When the second receiving unit 12a receives the identification information transmitted from the transmission / reception device 10 (see FIG. 10), the shooting instruction unit 12d instructs the image pickup device 22 to start shooting. To send.

With reference to FIG. 11, the imaging device 22 includes an instruction signal receiving unit 22a, a control unit 22b, an imaging unit 22c, and a shooting information recording unit 22d.

The receiving device 12 and the imaging device 22 may be connected by wire, and the imaging device 22 may receive the signal transmitted from the receiving device 12 via the wire.

The instruction signal receiving unit 22a receives the photographing instruction signal transmitted from the photographing instruction unit 12d of the receiving device 12. The control unit 22b controls the image pickup unit 22c based on the shooting instruction signal received by the instruction signal reception unit 22a. The imaging unit 22c includes a camera and captures an image. In the present embodiment, the imaging unit 22c is driven and controlled by the control unit 22b to start shooting an image. The imaging unit 22c, for example, continues to shoot an image for a preset period of time.

The shooting information recording unit 22d records the video shot by the imaging unit 22c in association with the shooting time.

As described above, in the present embodiment, each imaging device 22 starts shooting an image when the receiving device 12 associated with itself receives the identification information from the transmitting / receiving device 10. That is, in this embodiment, when the moving body 50 approaches the receiving device 12, shooting is performed by the imaging unit 22c, and the captured image is recorded in the shooting information recording unit 22d in association with the shooting time. .. As a result, the user of the storage system 100 can not only analyze the movement path of the moving body 50 based on the information collected by the information collecting device 14, but also based on the image recorded by the imaging device 22. It can be confirmed that the moving body 50 actually moved on the analyzed movement path. As a result, the movement path of the moving body 50 can be grasped more accurately.

Although detailed description is omitted, for example, the image pickup device 22 can be provided on a traffic light, a utility pole, or the like.

The receiving device may have the configuration shown in FIG. FIG. 12 is a diagram showing a modified example of the receiving device. The receiving device 18 shown in FIG. 12 differs from the receiving device 12 shown in FIG. 4 in that it further has a position setting unit 18a. The position setting unit 18a sets in advance position information indicating the installation position of the receiving device 18 based on the GPS signal. The position information set by the position setting unit 18a is, for example, latitude and longitude indicating the position of the receiving device 18. The position information set by the position setting unit 18a is recorded in the second recording unit 12b as unique information. In the storage system provided with the receiving device 18 instead of the receiving device 12, the position information is set in advance by the position setting unit 18a before the process shown in FIG. 9 is executed. Further, in this case, since the analysis unit 16d of the analyzer 16 can analyze the movement path of the moving body 50 based on the position information set by the position setting unit 18a, the installation information storage unit 16b becomes unnecessary.

In the storage system using the receiving device 18, the same effect as that of the storage system 100 using the receiving device 12 can be obtained.

As described above, according to the present invention, it is possible to accumulate information for analyzing the movement path of a moving body even in an environment where a network is not constructed.
