Specifically, as illustrated in FIG. 7E, the control unit 201 sets the “received” flag among the passcodes stored in association with the device identifier included in the message to “ The row that was “1” is deleted, the “received” flag of the row whose “received” flag is “0” is set to “1”, and the value of the “valid” cell of the row is set to 1. To. That is, the pass code newly issued in step S23 becomes the received pass code.

Next, when the user B of the terminal device 30B borrows the rental bicycle borrowed by the user A, the user operates the terminal device 30B, and as in the case of the user A, performs the authentication operation (step S29) and selects the bicycle rental bicycle parking lot. To perform the operation (step S30) and to select a rental bicycle (step S31).
When the selected rental bicycle is notified, the vehicle management device 20 stores the value stored in the “valid” cell among the passcodes received by the attached device 10 fixed to the selected rental bicycle. The first pass code specified in (1) (the first pass code “2001” in the row where the “received” flag is 1) is acquired from the storage unit 202, and the acquired pass code is displayed on the Web. The page is transmitted to the terminal device 30B (step S32). When receiving the Web page, the terminal device 30B displays the received Web page. Thereby, the user B can know the pass code for using the rental bicycle selected by the user B (step S33).

Next, a second operation example of this embodiment will be described with reference to FIG. The second operation example is an operation example when the passcode transmitted in step S24 of the first operation example cannot be received by the attachment device 10. In addition, before step S24 shown in FIG. 8, the operation | movement of step S1-step S23 of a 1st operation example is performed, and the passcode of FIG.7 (c) is memorize | stored in the vehicle management apparatus 20. FIG. Assume that the accessory device 10 stores the pass code of FIG.
As shown in FIG. 8, when the accessory device 10 cannot receive a plurality of passcodes transmitted from the vehicle management device 20 in step S24, the accessory device 10 uses the second passcode set in step S21. “2342” is set as a passcode for unlocking the electronic lock 3. Note that the vehicle management device 20 periodically transmits a newly issued passcode until it receives a message notifying that the passcode has been set by receiving the passcode from the attached device 10.

  Here, when the user B borrows the rental bicycle borrowed by the user A, the user operates the terminal device 30B, and as with the user A, the authentication operation (step S40) and the operation of selecting the bicycle parking lot of the rental bicycle ( Step S41), an operation of selecting a rental bicycle (step S42) is performed.

If the pass code from the vehicle management device 20 is not transmitted after step S20, the auxiliary device 10 does not transmit a message notifying that the pass code has been received (that is, the auxiliary device 10 does not transmit the pass code). Only when the passcode for unlocking is set to the received passcode, a message notifying that the passcode has been received is transmitted). If the vehicle management device 20 does not receive a message notifying that a passcode has been received despite the transmission of a plurality of passcodes in step S24, the passcode transmitted in step S24 is transmitted by the attached device 10. Judge that it has not been received.
If the selected rental bicycle is notified from the terminal device 30B while the plurality of new passcodes transmitted in step S24 are not received by the attachment device 10, the vehicle management device 20 will notify the selected rental bicycle. Passcodes that have been received by the fixed attached device 10, that is, a plurality of passcodes transmitted in step S3 (passcodes in the rows in which the “received” flag is 1 in FIG. 7C) Among these, the terminal device 30B displays a Web page that displays the passcode specified by the value “2” stored in the valid cell (ie, the second received passcode (here, “2342”)). (Step S43). When receiving the Web page, the terminal device 30B displays the received Web page. Thereby, the user B can know the pass code for using the rental bicycle selected by the user B (step S44).

  Thereafter, the user B goes to the bicycle rental bicycle parking lot and operates the accessory device 10 provided in the selected rental bicycle. User B first presses the start button. When the start button is pressed, the accessory device 10 displays a message that prompts the user to enter a passcode. Next, when the user B inputs “2342” of the passcode displayed on the Web page using the numeric keypad of the operation unit 104, the attachment device 10 receives the input passcode (step S45), and the received passcode is displayed. It is determined whether the electronic lock 3 is set as a passcode for unlocking. Here, since the accepted passcode “2342” is set as the passcode for unlocking the electronic lock 3 by the processing of step S21, the attachment device 10 unlocks the electronic lock 3 (step S46). Thereby, the user B can use a rental bicycle.

As described above, in the present embodiment, even when the user A steals a passcode when the user A inputs the passcode, the vehicle management device 20 and the accessory device 10 communicate with each other and borrow a rental bicycle. Since the passcode is changed when changing, rental bicycles can be prevented from being stolen.
In addition, bicycle rental bicycle parking lots may be provided indoors or bicycle parking lots where radio waves are difficult to reach or where radio waves do not reach. In the present embodiment, even when the rental bicycle is in a place where the radio wave condition is poor and the passcode cannot be transmitted from the vehicle management device 20 to the accessory device 10, the electronic lock 3 is unlocked when the user changes. Therefore, the next user can use the rental bicycle.
Further, before the user reserves a rental bicycle, a pass code is set when the accessory device 10 is in a state where communication is possible, and the vehicle management device 20 manages the pass code set by the accessory device 10. Even if the vehicle management device 20 is in a state where it cannot transmit the pass code to the accessory device 10, the pass code for unlocking the electronic lock 3 can be transmitted to the user.

In addition, you may combine each of embodiment mentioned above and the following modifications.

  In the embodiment described above, the accessory device 10 may delete the used passcode from the storage unit 102.

  In the present invention, there are a plurality of rental bicycles, and an accessory device 10 is provided for each rental bicycle. When the vehicle management device 20 transmits a pass code to the attachment device 10, the vehicle management device 20 may not transmit the same pass code as the pass code stored in the other attachment device 10. When there are a plurality of accessory devices 10 that store the same passcode, if a rental bicycle having these accessory devices 10 is adjacent to each other, the bicycle is unlocked when the user enters a passcode for a bicycle that is not reserved. Can cause problems. According to this modification, the same passcode is not used, and it is possible to avoid the problem that the user is unlocked when the passcode is input to a bicycle that is not reserved.

In the embodiment described above, when the accessory device 10 continuously receives a passcode different from the set passcode for a predetermined number of times (for example, three times), it does not receive the input passcode for a predetermined period (for example, 30 minutes). You may do it. Note that the predetermined number of times is not limited to three, and may be any other number, and the predetermined period may be other than 30 minutes.
Further, when the accessory device 10 continuously receives a passcode different from the set passcode for a predetermined number of times, the accessory device 10 may transmit information notifying that an incorrect passcode has been input to the vehicle management device 20. In addition, the vehicle management apparatus 20 that has received this information transmits an e-mail notifying the user that he / she has booked a rental bicycle to which the attached apparatus 10 that has transmitted the information is fixed that he / she has entered an incorrect passcode. You may do it. In addition, when the user who has received this e-mail accesses the vehicle management device 30 with the terminal device 30 and performs an operation instructing the accessory device 10 to accept the passcode, for example, a message instructing to accept the passcode. May be transmitted from the vehicle management device 20 to the attachment device 10, and the attachment device 10 that has received this message may cancel the state in which the passcode is not accepted. By doing so, it is possible to improve user convenience while increasing security.
FIG. 9 is a block diagram illustrating a functional configuration of the accessory device 10 according to the present modification, and FIG. 10 is a block diagram illustrating a functional configuration of the vehicle management apparatus 20 according to the present modification. In the accessory device 10 according to the present modification, an information transmission unit 1005 that transmits information notifying that an incorrect passcode has been input to the vehicle management device 20 is realized. Further, in the vehicle management device 20 according to the present modification, the second transmission unit 2002 is controlled so as to receive the information transmitted by the information transmission unit 1005 and transmit an e-mail notifying that an incorrect passcode has been input. The information receiving unit 2004 is realized.

  In the above-described embodiment, the bicycle is unlocked. However, the embodiment is not limited to the bicycle, and may be a motorbike or an automobile as long as it is a vehicle. In the case of an automobile, the “bicycle parking identifier” may be a “parking parking identifier”.

  In the above-described embodiment, when the newly issued and transmitted passcode is not received by the attached device 10, the attached device 10 is configured to set the passcode in the order received. The configuration for setting the code is not limited to this configuration. For example, a passcode and information indicating the order in which the passcode is used may be transmitted as a set, and the passcode may be set according to this order. When the pass code is a 4-digit number as described above, the pass code may be set in order from the smallest value, or may be set in order from the largest pass code. Further, the pass code is not limited to a 4-digit number, and may be 5 digits or more or 3 digits or less, and may be configured to use not only numbers but also alphabets.

In the embodiment described above, one pass code effective for unlocking the electronic lock 3 is set. However, the present invention is not limited to one, and a plurality of pass codes may be used. For example, in step S5, the attachment device 10 may set two pass codes, that is, a first pass code and a second pass code, as pass codes for unlocking the electronic lock 3. In this case, the vehicle management device 20 transmits a web page displaying the first passcode and the second passcode to the user terminal device 30 in step S10.
When the user inputs the displayed first pass code or second pass code, the electronic lock 3 can be unlocked.

In the above-described embodiment, the device identifier and the bicycle parking lot identifier are transmitted from the accessory device 10 to the vehicle management device 20, and the vehicle management device 20 can know which bicycle parking lot the accessory device 10 is in. The vehicle management device 20 stores the device identifier and the bicycle parking lot identifier in association with each other, and when transmitting the passcode to the auxiliary device 10, the passcode transmitted to the auxiliary device 10 in which the same bicycle parking lot identifier is associated and stored. The same passcode may not be transmitted. This prevents the same passcode from being used in the same bicycle parking lot, and avoids the problem of being unlocked when the user enters the passcode for an incorrect bicycle (bicycle that has not been reserved). Can do.
For example, when the accessory device 10A with the device identifier “A001” and the accessory device 10B with the device identifier “A002” are in the same bicycle parking lot and a new passcode is transmitted to the accessory device 10B, as shown in FIG. The accessory device 10B does not transmit the pass code transmitted to the accessory device 10A, but transmits another pass code. Further, for example, when the accessory device 10A having the device identifier “A001” and the accessory device 10C having the device identifier “A003” are in different parking lots, when a new passcode is transmitted to the accessory device 10C, FIG. As shown, the same passcode as the passcode transmitted to the attachment device 10A may be transmitted to the attachment device 10C.
Further, in the configuration in which the device identifier and the bicycle parking lot identifier are stored in association with each other, when the pass code is transmitted to the auxiliary device 10, it is parked in a bicycle parking lot within a predetermined range from the bicycle parking lot where the auxiliary device 10 is parked. A pass code different from the pass code received by the rental bicycle accessory 10 may be transmitted. For example, it is assumed that a bicycle parking lot B with a bicycle parking lot identifier “S002” is within a predetermined range from a bicycle parking lot A with a bicycle parking lot identifier “S001”. Here, when the vehicle management device 20 is parked in the bicycle parking lot B and transmits the passcode to the attached device 10C having the device identifier “A003”, the vehicle management device 20 has the bicycle parking identifier “S001” as illustrated in FIG. A pass code different from the pass code transmitted to the accessory devices 10A and 10B in the bicycle parking lot A is transmitted.
The same as the pass code transmitted to the attached devices 10A and 10B in the bicycle parking lot A having the bicycle parking identifier "S001" when the pass code is transmitted to the attached device 10C having the device identifier "A003" parked in the bicycle parking lot B When the pass code is transmitted, when the rental bicycle having the attached device 10A or the attached device 10B moves from the bicycle parking lot B and is parked in the bicycle parking lot A, the same pass code can be used in the same bicycle parking lot. When a pass code is input to a bicycle that has not been reserved, there may be a problem that the electronic lock 3 is unlocked.
According to this modification, since the same passcode as that of the attachment devices 10A and 10B is not stored in the attachment device 10C, it is possible to prevent such a problem from occurring.

In the embodiment described above, when the vehicle management device 20 transmits a pass code, it may not transmit the same pass code as the pass code stored in the attached device 10 provided in the rental bicycle being rented. . Specifically, in the above-described embodiment, the vehicle management apparatus 20 receives a message notifying the start of rental. As shown in FIG. 12, the vehicle management device 20 stores the usage status in association with the device identifier. When this message is received from the attachment device 10, the usage status is set to “in use”. When the vehicle management apparatus 20 receives a message notifying the end of rental, the vehicle management apparatus 20 sets the usage status to “waiting for use”. When a new passcode is transmitted to the attached device 10B whose device identifier is “A002” and the usage status is “waiting for use”, the vehicle management device 20 is “in use” as shown in FIG. A passcode different from the passcode received by the attached device 10A having the device identifier “A001” is transmitted to the attached device 10B.
When the same passcode as the passcode stored in the currently used accessory device 10A is stored in the rental bicycle accessory device 10B waiting for use, the rental bicycle of the accessory device 10A is placed in the same bicycle parking lot as the rental bicycle of the accessory device 10B. When parked and waiting for use together, the same passcode can be used in the same bicycle parking lot, and the electronic lock 3 is unlocked when the user enters a passcode for a bicycle that has not been reserved Can occur.
According to the present modification, the passcode stored in the accessory device 10A and the passcode stored in the accessory device 10B are not the same, so that such a problem can be prevented from occurring.

  Alternatively, the plurality of accessory devices 10 may be divided into a plurality of groups that divide the region, and the same passcode may not be transmitted to the accessory devices 10 belonging to the same group. For example, the attached device 10A with the device identifier “A001” and the attached device 10B with the device identifier “A002” are group A, the attached device 10C with the device identifier “A003”, and the attached device with the device identifier “A004”. Assume that the device 10D is grouped into B groups. In this case, as shown in FIG. 13, the same passcode is not issued within the group for the auxiliary device 10A and the auxiliary device 10B belonging to the A group. Further, as shown in FIG. 13, the same passcode is not issued in the group for the attached device 10C and the attached device 10D belonging to the B group. Since the attached device 10A and the attached device 10C belong to different groups, the same passcode may be issued as shown in FIG. Thereby, it is possible to prevent the passcodes from overlapping in the attached devices 10 belonging to the same group.

You may make it transmit the pass code different from to the attachment apparatus 10 in the said bicycle parking lot.
For example, the attached device 10A with the device identifier “A001” is located at the bicycle parking lot at the position (X1, Y1), and the attached device 10B with the device identifier “A002” is within the predetermined range from the position (X1, Y1). Is assumed to be located at (X2, Y2) and being in use. In this case, as shown in FIG. 14, a pass code different from that of the accessory device 10B is transmitted to the accessory device 10A.
In the above-described embodiment, the position of the attachment device 10 may be grasped by the bicycle parking lot identifier. In the case of this configuration, the accessory device 10 that has received the bicycle parking identifier transmits the device identifier and the bicycle parking identifier to the vehicle management device 20, and the vehicle management device 20 associates the bicycle parking identifier received by the accessory device 10 with the device identifier. Remember.
In this configuration, the accessory device 10A is located at a bicycle parking lot whose parking lot identifier is “NE001”, and the accessory device 10B is located at a position within a predetermined range from the position of this bicycle parking lot (X2, Y2) and used. Assume that it is in the middle. In this case, the bicycle parking lot coordinates (X1, Y1) stored in advance linked to the bicycle parking identifier are acquired, and a passcode different from that of the attached device 10B located at the position (X2, Y2) within the predetermined range is obtained. Transmit to the attached device 10A.
According to these configurations, when a pass code is transmitted to the accessory device 10, a pass code different from the pass code stored in the accessory device 10 within a predetermined range from the accessory device 10 is transmitted to the accessory device 10. Can do.
When the same passcode as the passcode stored in the accessory device 10B is stored in the accessory device 10A, when the rental bicycle of the accessory device 10B is parked in the same bicycle parking lot as the rental bicycle of the accessory device 10A and both are waiting for use, When the same passcode can be used in the same bicycle parking lot and the user enters a passcode for a bicycle that has not been reserved, there may be a problem that the electronic lock 3 is unlocked.
According to the present modification, the passcode stored in the accessory device 10A and the passcode stored in the accessory device 10B are not the same, so that such a problem can be prevented from occurring.
