Specifically, the analyzer 16 can analyze the movement path of the transmission device 10, that is, the movement path of the moving body 50 for each identification information.

Further, in the present embodiment, each receiving device 12 records the identification information of the transmitting device 10 and the reception time of the identification 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 path of the moving body 50 individually from the plurality of receiving devices 12. Can collect information for. 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 collection system 100 can be reduced as compared with the case where the information collection device 14 acquires information from the reception device 12 using satellite communication.

[Modification example]
The transmitting device 10 may be a beacon device that transmits identification information at regular intervals with a predetermined radio wave strength. More specifically, as the transmitter 10, an iBeacon (registered trademark) using BLE (Bluetooth (registered trademark) Low Energy) provided by Apple Inc. may be used. 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 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 receiving device may have the configuration shown in FIG. FIG. 8 is a diagram showing a modified example of the receiving device. The receiving device 18 shown in FIG. 8 is different 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 recording unit 12b as unique information. In the collection 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. 7 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 collection system using the receiving device 18, the same effect as that of the collecting system 100 using the receiving device 12 can be obtained.

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