It is a communication system having a history information storage device 20 for storing. Here, in this embodiment, the network 50 is a public wide area radio access network, and the network 60 is the Internet.
Further, a terminal device 31 used by a person 30 who wants to refer to history information is connected to the Internet 60. Here, in this specification, the “wireless IC tag” stores at least information such as its own identification code (ID) and has a function of communicating with an external management system using radio waves. This is a small wireless IC chip, and includes both a type with a built-in power supply and a type with power supplied from the outside.

When the object that generates history information is a moving object as in the present embodiment (automobile 40), communication between the wireless IC tag 10 and the history information storage device 20 is realized by a wireless access method. In that case, since the location of the object that generates the history information cannot be limited, it is desirable to use a public and wide area wireless access network operated by the communication carrier. For example, a PHS (registered trademark) network or a mobile phone network.
On the other hand, as long as the history information referencer 30 can access the history information storage device 20, the history information referencer 30 may use the convenient one of the history information referencer 30 in either the wired access network or the wireless access network.

The ID unique to the wireless IC tag 10 is searched, the history information accumulated for each ID unique to the corresponding wireless IC tag 10 is read out and transmitted to the terminal device 31.

FIG. 2 shows a specific configuration of the wireless IC tag 10 attached to the automobile 40, which is an object that generates the history information shown in FIG. Here, it is assumed that the history information report is the travel distance of the automobile 40.
In FIG. 2, the wireless IC tag 10 includes history information acquisition means 100 that acquires history information generated by the automobile 40, and history information and an ID unique to the wireless IC tag 10 via the networks 50 and 60. A transmission unit 110 that periodically transmits to the storage device 20, a history information acquisition unit 100, a control unit 120 that controls the transmission unit 110, and a power supply unit 130 that supplies power to each unit.
The history information acquisition unit 100 includes a buffer that temporarily holds the acquired history information.
The control unit 120 includes a holding unit that holds an ID that is unique identification information given to the wireless IC tag 10. This holding means is a non-volatile memory such as a ROM that stores and holds IDs in a fixed manner.

The wireless IC tag 10 periodically acquires travel distance information by the history information acquisition unit 100 and transmits it to the history information storage device 20 (FIG. 1) by the transmission unit 110. The travel distance information can be obtained electronically from the odometer of the automobile 40 or the electronic control unit. A series of operations is controlled by the control means 120.
The power consumed by the wireless IC tag 10 is performed by the power supply unit 130. The power supply means 130 is of a built-in power supply type, for example, a button-type battery, but as a type of supplying power from the outside, when supplying from the battery of the automobile 40, using a solar cell, etc. This is not the case. That is, the power consumed by the wireless IC tag 10 may be supplied from a built-in power source or may be supplied from the outside.

  Next, a specific configuration of the history information storage device 20 in FIG. 1 is shown in FIG. In the figure, a history information storage device 20 includes a history information storage unit 200, a reception unit 210 that receives an ID and history information from the wireless IC tag 10, and a history information storage unit in response to a reference request from a history information reference person. 200 includes a transmission unit 220 that transmits the history information read from 200 to the terminal device 31 used by the history information referencer 30, and a control unit 230 that controls each unit.

In the above configuration, the travel distance information periodically transmitted from the wireless IC tag 10 is received by the receiving unit 210. The received travel distance information is accumulated by the history information accumulation means 200.
A person (history information reference person) 30 who intends to refer to the travel distance information uses the terminal device 31 to refer to the travel information of the automobile 40 to the history information storage apparatus 20 (specific ID given to the wireless IC tag 10). ).

The history information storage device 20 that has received the reference request data by the receiving unit 210 transmits the corresponding travel distance information by the transmission unit 220 to the terminal device 31 that has transmitted the reference request data.
The history information storage device 20 can be realized by a server or the like connected to the Internet 60.

  FIG. 4 shows an example of a history information accumulation method in the history information accumulation means 200. As shown in the figure, different directories are prepared in advance for each ID of the wireless IC tag 10, and history information transmitted from the wireless IC tag whose ID is 101 is like a directory corresponding to the wireless IC tag ID = 101. History information is accumulated for each wireless IC tag.

Next, FIG. 5 shows the processing contents when the history information storage apparatus in FIG. 1 stores the history information. It is assumed that the IC cug ID and history information type, which are information of the wireless IC tag 10, are registered in advance in the history information storage center.
When the history information storage device 20 receives the IC tag ID and history information from the wireless IC tag 10 (step 300), whether or not the wireless IC tag ID is registered, that is, a directory corresponding to the received IC tag ID exists. It is determined whether or not to perform (step 301).

  If registered, the history information transmitted together with the wireless IC tag ID is stored in the corresponding directory (step 302). If not registered, a message is sent to the transmission source indicating that it is an unregistered ID and the history time signal cannot be stored. Then, the wireless IC tag ID and the history information transmitted are discarded (step 304).

The error message reply to the transmission source (wireless IC tag 10) may be omitted if the wireless IC tag 10 does not have a reception function. Omitting the receiving means is common as a cost reduction method for wireless IC tags.
In order to avoid impersonating a fake wireless IC tag as if it was a correct wireless IC tag and transmitting history information and storing it in the history information storage device 20, the wireless IC tag is appropriately encrypted. It is desirable to keep the ID secret.

  Next, FIG. 6 shows the processing contents of the history information storage device 20 when referring to the history information. In the figure, a person 30 who wants to refer to history information uses the terminal device 31 to obtain reference request data including a wireless IC tag ID, which is identification information of the wireless IC tag 10 attached to the reference object (automobile 40). The information is transmitted to the information storage device 20, and the history information storage device 20 receives the reference request data (step 400).

The history information storage device 20 performs user authentication in order to confirm whether the person who transmitted the reference request has the right (step 401). If the user does not have the right, an error message to that effect is returned and the history information is not referred to (step 404).
For a reference request that has passed in user authentication (step 401), the corresponding wireless IC tag ID is searched to determine whether or not the corresponding wireless IC tag ID exists (step 402).

If the corresponding wireless IC tag ID exists, the history information (travel distance) stored under the directory is transmitted to the terminal device 31 used by the history information referencer 30 (step 403). If the corresponding wireless IC tag ID does not exist, an error message indicating that the history information does not exist is returned (step 405).
Whether to perform user authentication should be determined according to the openness of the history information. If user authentication is implemented, the possibility of being referred to by an unspecified number of people can be greatly reduced, but conversely, if anyone wants to be able to refer easily, user registration is required in advance, making it cumbersome. Because it will increase.
When it is desired to increase the openness of the history information so that anyone can refer to it, the user authentication process shown in this embodiment should be omitted.

  According to the present embodiment, since the history information itself is stored and managed in a different place away from the object that generates the history information, the risk of falsification of information by a malicious person can be reduced.

  According to the communication system, the history information storage method, and the history information reference method according to the present invention described above, the merit of storing the history information is obtained because the usage history information is an important factor for determining the price. There may be a trading market. There can be many examples including the operation period and load history of construction machines, machine tools, etc., the usage period of musical instruments, and the number of hits of a golf club, including the automobile described in this embodiment.
