The portable terminal device 200 receives the first communication from the vehicle-mounted common device 100 via the second device connection control processing unit 205.
The data stored in the data storage unit 107 can be received. In addition, the portable terminal device 200 is an interface.
New data input from the second data input control unit 201 or the second user input control unit 202 which can input information from the network or information on a camera attached to the PC is registered in the first data storage unit 107. You can also. At this time, the second
The synchronization information storage unit 204 manages the history of data transfer.

The user of the portable terminal device registers the data by connecting the first device connection control processing portion 105 on the shared device side and the second device connection control processing portion 205 on the portable terminal device side. When performing the above, the setting type of the user individual information file existing on the shared device may be changed from the second user input control unit 202 to “unconditional release”, “selective release”, “unconditional non-disclosure”, Attributes such as “capture”, “non-capture”, and “selective capture” of the public data must be input and set in advance.

The portable terminal device and the in-vehicle shared device both have a data synchronization log file which is a file for adding and holding an individual ID which can be identified by the user. for that reason,

FIGS. 3 to 5 show an embodiment of a data synchronization system for a shared device and one or more terminal devices according to the present invention when data is synchronized between a vehicle-mounted shared device and a portable terminal device. FIG. 4 is an explanatory diagram of an operation processing flow on the in-vehicle shared device side, and constitutes one flowchart as a whole.

First, at the beginning of the operation flow, a wired connection (serial or US) between the in-vehicle shared device and the portable terminal device is performed.
B), wireless (IrDA or Bluetooth), or an interface by inserting and removing a memory card, and performs device connection processing until data link is completed. As the transmission and reception protocol, a method determined by each interface is used.

Next, when the connection processing is completed, a request command for confirming the presence or absence of a data synchronization log file is sent from the vehicle-mounted shared device to the portable terminal device, so that the data synchronization log file is transmitted to the portable terminal device. Check for presence.

The overall operation flow is described on the assumption that the two devices that perform synchronization have a data synchronization log file from the beginning, so if the data is transferred to the portable terminal device, If no data synchronization log file exists, the operation flow ends at this point.

When a data synchronization log file exists, the synchronization log file is read from the portable terminal device to the in-vehicle shared device.

The user ID is confirmed from the data synchronization log file obtained from the portable terminal, and the data synchronization log file of each data synchronization log file held by the on-vehicle device (a plurality of data files corresponding to the number of users) is checked. Check if it matches the user ID. As a format of the data synchronization log file, for example, a data synchronization log file shown in FIG. 8 described later may be used.

If the user ID included in the data synchronization log file fetched from the portable terminal does not exist on the vehicle-mounted device side, it is regarded as a new user for the vehicle-mounted device,
A data synchronization log file is newly generated with this user ID.

After setting the data check counter, the number of data records is confirmed from the data synchronization log file on the vehicle-mounted device.

If the number of data records registered in the data synchronization log file of the vehicle-mounted device is 0 (for example, when a log file is generated with a new user ID), the data synchronization of the portable terminal is performed. Check the number of data records from the log file.

If the number of data records on the portable terminal side is also 0
If so, there is no need to update, so this synchronization processing ends.

If the number of data records is not 0, the information of the data synchronization log file on the portable terminal side is the state of the latest data file. Is regarded as a data synchronization log file.

On the other hand, when one or more data records exist on the vehicle-mounted device side, the record information is read from the first record.

Next, a record having the same file name is searched from the data synchronization log file on the portable terminal side, and if this record can be confirmed on the portable terminal side, the dates of both record update histories are confirmed.

When the on-vehicle device is new, record information on the on-vehicle device is set in the new data synchronization log file.

When the portable terminal is new, the record information of the portable terminal is reflected in the new data synchronization log file.

If there is no data record on the portable terminal side, the data record on the vehicle-mounted device is reflected in the new data synchronization log file.

This record confirmation process is repeated by the number of data records on the vehicle-mounted device side.

After the loop based on the data records on the vehicle-mounted device ends, it is checked whether all the records in the portable terminal-side synchronization log file have been merged.

If there is a file whose information has not yet been reflected in the new log file (since this is information of a data file newly registered on the information terminal side), the new data synchronization log file is added to the new data synchronization log file. Set the remaining records for.

At the stage where both the in-vehicle device and the portable terminal have finished updating all data to the latest state, the data is not included in the newly created data synchronization log file and is newly added by another user. The record of the new file that has been made public is combined with the new data synchronization log file.

Here, the description is made on the assumption that the data synchronization is set to “capture” in the settings of the user's individual setting information file (detailed description in FIG. 10). If this is set to non-import, this processing is not performed.
In addition, if it is selected and imported, GUI output etc.
It is also possible to confirm whether or not each file has been imported.

The data file reference table is updated based on the information of the newly created data synchronization log file.
The updating operation is performed by increasing or decreasing the reference count for each file.

At this time, since the file whose reference count has become 0 is not referred to by any user, the file is also deleted.

The in-vehicle device transmits the new data synchronization log file created so far to the portable terminal.

Next, the in-vehicle device transmits a necessary new data file group, if any, on the portable terminal side.

Further, the vehicle-mounted device receives a new data file group necessary for the vehicle-mounted device from the portable terminal side.

In the operation flow, the apparatus is finally disconnected and the processing is terminated.

FIG. 6 shows an embodiment of a data synchronization system for a shared device and one or more terminal devices according to the present invention. FIG. 9 is an explanatory diagram of an operation processing flow on the device side.

First, at the beginning of the operation flow, the same device connection processing as described with reference to FIGS. 3 to 5 is performed between the portable terminal and the vehicle-mounted device until the completion of the data link.

When the connection process between the portable terminal and the on-vehicle device is completed, the portable terminal transmits the held data synchronization log file to the on-vehicle device.

Thereafter, the portable terminal waits for reception of a new data synchronization log file from the in-vehicle device, and receives this data when transmitted.

Next, a new required data file is transmitted from the vehicle-mounted device side.
This data is received.

Further, the mobile terminal transmits a data file on the mobile terminal, which is newly required on the vehicle-mounted device side, to the vehicle-mounted device after synchronization with the vehicle-mounted device.

The portable terminal refers to the new data synchronization log file received earlier and deletes unnecessary data files on the portable terminal.

In the operation flow, the apparatus is finally disconnected and the processing is terminated.

FIG. 7 shows a data registration setting change processing flow in one embodiment of the data synchronization system for a shared device and one or more terminal devices according to the present invention. Operation flow of FIG.
FIG. 8 is an explanatory diagram when a certain user on the mobile terminal sets “public” to the registration setting type of the user individual setting file and then changes this setting to “non-public” on the vehicle-mounted device again.

First, the operation flow starts from the user.
The user ID information of the mobile terminal is acquired by a GUI or the like.

[0094] The user can be obtained from the user individual setting information file group.
Select the user individual setting information file equal to the ID and change the registered setting type in this file. After that, the data file reference table is read.

In the read data file reference table, the owner ID (to be described later) of each data record and the user ID are compared to search for an equal record. If there is no equal record, the process ends.

If there is an equal record, it is checked whether the reference count is 1 (1 if only the user is referencing this file).

If the reference count is not 1, the attribute of this data file cannot be changed because another user has already referred to it. Find the next record.

If the reference count is 1, only the user himself / herself is being referred to, and the public type of the record is set to private.

This setting change processing is repeated by the number of data records.

When there is no more search record, this data registration setting change processing flow ends.

FIG. 8 shows an example of the contents of a data synchronization log file which is managed for each user who uses the system in one embodiment of the data synchronization system for a shared device and one or more terminal devices according to the present invention. FIG.

This file is largely divided into two blocks, and has a structure in which the data is transferred from the end of the previous block to the subsequent block with an arrow to represent the data entity.

As the contents of the file, the first half block is composed of the following three components.

User ID: Each user has an arbitrary ID (Identification) for user identification.

Here, the Roman alphabet of the name is used as the ID.

Number of retained records: Number of data file records referenced by this user.

In any state, that is, unreproduced, reproduced, changed, deleted, is referred to. However, regarding the deletion, if the target data is deleted from all other users, the corresponding record of the data file is deleted from the on-vehicle equipment system, and at the same time, the data synchronization log file is deleted. The record information with the deletion inside is also deleted.

Displacement to synchronization information: Offset to data record of subsequent block.

[0092] The information of the subsequent block is the data referred to by the user, the latest state of the user's access to this data (unreproduced, reproduced, updated, deleted) and access update date / time information. .

FIG. 9 shows an embodiment of a data synchronization system for a shared device and one or more terminal devices according to the present invention, in which data necessary for managing a data file to be held on the vehicle shared device is shown. It is an explanatory view of a file reference table.

This file has, for each data, a reference count indicating the number of users accessing the data file, an owner ID indicating who registered the data in the system, and an owner indicating the file in the system. It is composed of a public type (public / private) indicating how to handle the above.

FIG. 10 shows an embodiment of a data synchronization system for a shared device and one or more terminal devices according to the present invention.
FIG. 5 is an explanatory diagram of a user individual setting information file for managing information individually set by each user who uses the present system.

The user individual setting information file is composed of three components.

User ID: This is for distinguishing individual users who use this system, and is also information for distinguishing users in this user individual setting information file.

Data registration: Information that defines the handling of data in the system when the user registers data in the system.

As the setting type, any of “public”, “non-public”, and “selective public” can be set.
When "Public" is selected, the registered data is always released to other users, and if other users take in the data synchronization settings described later, this user can also refer to the registered data. Will be possible.

When "non-public" is selected, the data is always registered as private, and other users do not know the existence of the data file. It can be set and used when you want to manage private data synchronously.

"Selected release" is used to set the release type for each data when registering the data.

Data synchronization: Information specifying how to handle a data file registered by another user when the user synchronizes the portable terminal device with the in-vehicle shared device. The setting types are "import", "non-import",
Any setting of “selection capture” is possible. If "Import" is selected, all data files registered on the in-vehicle device by another user and whose registration setting type is "public" can be unconditionally imported when the synchronization process is performed. If “non-loading” is selected, even if there is a data file whose registration setting type is “public” on the vehicle-mounted device at the same time when the synchronization process is performed, these data files are ignored and not loaded. In addition, "select capture"
When setting is made, when synchronization is performed, it is possible to list data files whose registration setting type is "public" that exists on the in-vehicle system and select from them and import them .

According to the setting of this file, when the car is shared but the user does not want to disclose or take in the information, such as the family, or is shared as the business vehicle of the company, the data such as the sales information is shared by all users. If you want to share, you can set up and operate the system according to each case, such as when the on-board system has a small amount of memory tower and you want to share all data and suppress duplicate registration of data as much as possible .

In the above embodiment, a combination of an in-vehicle device and a portable terminal device has been described as an example. For example, the system of the present invention is installed in a personal information terminal device connected to a home TV receiver and a home network. You can also. It can also be used for servers in offices and personal terminals. That is, it is clear that the shared device and the terminal may be of a stationary type. Although the present invention has been described in connection with a combination system of a shared device and one or more terminal devices, the shared device or the terminal device may independently constitute the present invention and be used as the above-described combined system. it is obvious.
