Description

  The present invention relates to a data processing terminal and a data processing method. More specifically, the present invention relates to a data processing terminal and a data processing method that are installed at a location out of reach of a user while eliminating a transition to a connection authentication procedure unintended by the user as much as possible. The present invention relates to a data processing terminal and a data processing method that are wirelessly connected to the terminal.

  With the spread of digital devices, especially mobile devices, short-range wireless communication technology has become more familiar to us. For example, in a home, a user can handle print and scan functions by connecting a personal computer and a printer using a wireless LAN and sending data via wireless. In addition, music data stored on a mobile terminal such as a mobile phone can be reproduced from a wirelessly connected speaker using Bluetooth (registered trademark).

  These short-range wireless communication technologies have improved problems such as cable aging and damage to connectors that have occurred during wired connections. However, the short-range wireless communication technology uses a predetermined frequency band such as 2.4 GHz band or 5 GHz band, and noise is superimposed on transmission data or data is lost due to interference / interference with other devices. there is a possibility. In addition, since the connection is wireless, there is a possibility of connection with a device not intended by the user or an attack from a malicious user. For this reason, in general, in order to establish a secure connection, various encryption techniques are employed, and connection authentication (called pairing in Bluetooth) is performed by the user entering a personal identification number. Thus, only the device intended by the user can be connected.

  As described above, digital devices can be wirelessly connected to exchange desired data. However, unless the digital device is equipped with a rechargeable battery or the like, an electric wire for power supply to the digital device is required, so that the wireless state is not completely achieved. Further, depending on the installation environment of the digital device, the scenery of the installation environment may be impaired, and the user may be overturned by being caught by the power cable.

  Therefore, an invention relating to a speaker arrangement system and a speaker device that uses power supply for ceiling lighting and receives and reproduces audio data by wireless communication is disclosed (Patent Document 1). Here, by using the power supply for the ceiling lighting, it is possible to provide a speaker system in which the cable including the power cable is not conspicuous.

Japanese Patent No. 5168632

As described above, in order to ensure security in the short-range wireless communication technology, a connection authentication procedure is required. Here, considering the procedure of the connection authentication procedure, for example, in the case of Bluetooth, the following procedure is required.
(1) Set each device to be connected to a state in which connection authentication is possible.
(2) At this time, the connected side becomes a pairable (searchable) state.
(3) The connection side searches for peripheral connectable devices by Bluetooth and finds a connected device.
(4) Pairing processing is performed between the discovered connected device and the connected device.
(5) The user inputs the personal identification number designated for the connected device. However, if the connected device does not have a UI (User Interface), the input of the personal identification number may be omitted.

When performing such a connection authentication procedure in a system installed at a position (ceiling) where it is difficult for the user to touch directly like the invention shown in Patent Document 1,
(A) It is difficult to press hardware (switches) etc. (B) Equipment such as a remote control is necessary (mounting cost increases)
The problem arises. In addition, when a UI as described above is not prepared, it is conceivable to always maintain a connectable state between devices. As a result, the user does not have to operate the switch or the remote control, and the number of user operations can be reduced.

However, in this case
(C) Connection authentication from unintended users is allowed.
The problem arises. With regard to (C), for example, an avoidance method such as connecting to a device only for 1 minute after the main power is turned on can be considered. However, when considering a configuration that uses both the illumination and the main power supply as in Patent Document 1, even when the user turns on the main power supply with the intention of the illumination operation, the connection authentication is permitted, The same is true in the sense that an unintended user can be connected. In a state where the connection authentication is permitted, even if a user who has unintentionally connected to the device is a malicious user, if the malicious user has registered for connection authentication, the user can easily connect to the device. There is a risk of being connected.

  The present invention has been made in view of the above problems, and is installed at a location out of the reach of the user and wirelessly connected to the user terminal while eliminating as much as possible the transition to a connection authentication procedure not intended by the user.

Embodiments according to the present invention will be described below with reference to the drawings.
(First embodiment)
In this embodiment, a basic configuration of the present invention will be described. Note that data that can be transmitted and received by wireless connection are diverse, such as image data, sound data, and character data. In the present invention, description will be given as sound data.

As shown in FIG. 1A, a wireless connection system to which the data processing system according to the present embodiment is applied is installed at a user operation terminal (hand terminal 101) at a user's hand and at a place away from the user. Terminal (remote terminal 102). The remote terminal 102 corresponds to the data processing terminal of the present invention.
The remote terminal 102 is supported on the ceiling 104 as shown in the figure, for example. At this time, the remote terminal 102 can be supplied with power by connecting the remote terminal 102 instead of the ceiling light to a rosette for attaching a ceiling light or the like to the ceiling 104. Here, the user can operate the power supply from the main power source to the remote terminal 102 by using the wall surface switch 103 or the like, as in the case of turning on / off the main power source of a general ceiling light.

  Further, as shown in FIG. 1 (B), a ceiling light 105 or the like is placed under the remote terminal 102 of the wireless connection system by providing a rosette portion in the remote terminal 102 having the configuration shown in FIG. 1 (A). Can be connected.

Next, an example of the configuration of the remote terminal 102 is shown in FIG.
The remote terminal 102 establishes a wireless connection with the hand terminal 101, and receives a variety of data (for example, sound data, remote control data, etc.) from the hand terminal 101, and the communication terminal 201 for wireless connection. Data processing for receiving connection authentication data holding unit 202 for holding data (connection history, connection destination, main connection terminal, etc.) and various data from communication unit 201 and converting it into data for output to information presentation unit 204 A unit 203, an information presentation unit 204 (speaker unit) that outputs processing data received from the data processing unit 203, and a control unit 205 that controls each unit of the remote terminal 102. The control unit 205 includes, for example, a memory that stores a program for realizing each function of the remote terminal 102 according to the present embodiment, and a control processor that reads and executes the program from the memory. The connection authentication data holding unit corresponds to the storage unit of the present invention.

Next, the operation flow of the remote terminal 102 will be described with reference to FIGS.
FIG. 3 is a flowchart showing an example of the operation of the remote terminal. First, in step S1, when the main power source of the remote terminal 102 is turned on, the communication unit 201 of the remote terminal 102 refers to the connection authentication list held in the connection authentication data holding unit 202, and sets the referenced connection authentication list. It is confirmed whether there is registration (history) of the handheld terminal 101. The connection authentication list includes the connection priority when making a connection request to the local terminal 101, the terminal ID of the local terminal 101 whose priority is determined by the connection priority, and the main connection terminal for each local terminal 101. A main / sub flag for determining whether the terminal is a sub-connection terminal and a final connection flag indicating whether each terminal 101 is connected (final connection destination) or other state are registered. A specific example of this connection authentication list will be described later.

If there is a registration of the terminal 101 in the connection authentication list (step S1-Yes), the process proceeds to step S2. If there is no registration in the connection authentication list (step S1-No), the process proceeds to the initial authentication registration mode (step S14). The initial authentication registration mode is a process of performing a connection authentication registration procedure with the local terminal 101 that has transmitted the connection authentication request, and registering the local terminal 101 that has been registered for connection authentication as the main connection terminal.
Here, the operating state of the remote terminal is in the initialization mode. The initialization mode will be described later.

  In step S <b> 2, the communication unit 201 refers to the state of the connection authentication permission flag held in the connection authentication data holding unit 202. If the connection authentication permission flag is OFF (step S2-Yes), the process proceeds to step S3. If the flag is ON (step S2-No), the mode changes to the new authentication registration mode (step S15). The new authentication registration mode is a process of performing a connection authentication registration procedure with a terminal that has transmitted a connection authentication request and registering the terminal that has been registered for connection authentication as a main connection terminal or a sub connection terminal.

In step S <b> 3, the communication unit 201 refers to the connection authentication list held in the connection authentication data holding unit 202, and sends a connection request to the terminal 101 of the last connection destination (latest history) of the referenced connection authentication list. Here, the connection request is sent to the final connection destination local terminal 101, but the connection request may be transmitted from the connection authentication list to the local terminal 101 having the highest connection priority.
In step S4, the communication unit 201 determines whether or not the connection with the local terminal 101 that has sent the connection request is successful. If the connection is successful (step S4-Yes), the process proceeds to step S5. If the connection has failed (step S4-No), the process proceeds to step S8.

In step S <b> 5, the communication unit 201 transitions to a connection mode that maintains a connection with the local terminal 101. In the remote terminal 102, the amount of power can be reduced by turning on the power supply to the data processing unit 203 at the time of transition to the connection mode.
In step S <b> 6, the communication unit 201 receives various data from the connected hand terminal 101, converts the data into a form that can be processed by the data processing unit 203, and sends the data to the data processing unit 203. For example, if the received data is encoded sound data, the communication unit 201 decodes it and sends it to the data processing unit 203. The data processing unit 203 converts the received data into data to be presented by the information presentation unit 204 and sends the data to the information presentation unit 204. For example, the sound pressure level of the received sound data is changed or various equalizing is performed. The information presentation unit 204 presents the received data. For example, sound data generated for output is output from a speaker unit.

  In step S7, the communication unit 201 confirms the connection state. When the connection with the connected hand terminal 101 is disconnected (step S7—Yes), the process proceeds to step S12 and transitions to the standby mode. If the connection continues (No at Step S7), the process returns to Step S6 to continue receiving data.

On the other hand, when the connection is not successful in step S4, the communication unit 201 refers to the connection request mode held in the connection authentication data holding unit 202 in step S8. When the connection request mode is the list patrol request mode (step S8—Yes), the process proceeds to step S9. The list patrol request mode is a mode in which connection requests are made in the order of priority in the connection authentication list when connection to the terminal 101 of the final connection destination (or highest priority connection destination) is not possible.
If the connection request mode is the final connection mode (step S8—No), the process proceeds to step S12. The final connection mode is a mode in which a connection request is made only to the terminal 101 at the final connection destination in the connection authentication list.

  In step S <b> 9, the communication unit 201 determines whether connection requests have been made to all the local terminals 101 listed in the connection authentication list. When there is a local terminal 101 that has not made a connection request (step S9-No), the process proceeds to step S310. When connection requests are made to all the local terminals 101 and there is no local terminal 101 that has not made a connection request (step S9—Yes), the process proceeds to step S12.

In step S <b> 10, the communication unit 201 issues a connection request to the local terminal 101 that has not yet made a connection request in the connection authentication list and has the next highest connection priority.
In step S <b> 11, the communication unit 201 determines whether or not connection with the local terminal 101 that has transmitted the connection request is possible. If the connection is successful (step S11-Yes), the process proceeds to step S5, and the mode is changed to a connection mode for maintaining the connection with the terminal 101. If the connection fails (step S11-No), the process returns to step S9.

On the other hand, when a connection request is made to all the local terminals 101 in the list patrol request mode, the communication unit 201 shifts to a standby mode waiting for a connection request from the local terminal 101 in step S12. The standby mode is a mode for waiting for a connection request when no connection is established with any local terminal 101.
In step S13, the communication unit 201 waits for a connection request from the local terminal 101 that has been registered for connection authentication. If there is a connection request (step S13-Yes), a connection with the local terminal 101 that has made the connection request is established, and the process proceeds to step S5 and transitions to the connection mode. When there is no connection request (No at Step S13), the process returns to Step S12 and the standby mode is continued. Here, even if there is a connection request from the local terminal 101 that is not registered for connection authentication, it is determined that there is no connection request, and the standby mode is maintained.

In the operation example of FIG. 3, it is assumed that the remote terminal 102 sends a connection request to a terminal registered in the connection authentication list after the main power is turned on. You can choose not to send. FIG. 4 is a flowchart for explaining the operation at this time. Each step described in FIG. 4 performs the same processing as the step with the corresponding number in FIG.
Here, in step S1, the communication unit 201 of the remote terminal 102 refers to the connection authentication list held in the connection authentication data holding unit 202, and there is no registration (history) of the terminal 101 (step S1). -No), transition to the initial authentication registration mode (step S14). The initial authentication registration mode is a process of performing a connection authentication registration procedure with the local terminal 101 that has transmitted the connection authentication request, and registering the local terminal 101 that has been registered for connection authentication as the main connection terminal.

  In step S <b> 2, the communication unit 201 refers to the state of the connection authentication permission flag held in the connection authentication data holding unit 202. If the connection authentication permission flag is OFF (step S2-Yes), the process proceeds to step S12 in this example. If the flag is ON (step S2-No), the process proceeds to the new authentication registration mode (step S15). The new authentication registration mode is a process of performing a connection authentication registration procedure with the local terminal 101 that transmitted the connection authentication request, and registering the local terminal 101 that has been registered for connection authentication as a main connection terminal or a sub connection terminal.

When the connection authentication permission flag is OFF, in step S12, the communication unit 201 transitions to a standby mode that waits for a connection request from the local terminal 101. The standby mode is a mode for waiting for a connection request when no connection is established with any local terminal 101.
In step S13, the communication unit 201 waits for a connection request from the local terminal 101 that has been registered for connection authentication. If there is a connection request (step S13-Yes), a connection with the local terminal 101 that has made the connection request is established, and the process proceeds to step S5 and transitions to the connection mode. When there is no connection request (No at Step S13), the process returns to Step S12 and the standby mode is continued. Here, even if there is a connection request from the local terminal 101 that is not registered for connection authentication, it is determined that there is no connection request, and the standby mode is maintained.

  When shifting to the connection mode in step S5, in step S6, the communication unit 201 receives various data from the connected hand terminal 101, converts the data into a form that can be processed by the data processing unit 203, and sends the data to the data processing unit 203. For example, if the received data is encoded sound data, the communication unit 201 decodes it and sends it to the data processing unit 203. The data processing unit 203 converts the received data into data to be presented by the information presentation unit 204 and sends the data to the information presentation unit 204. For example, the sound pressure level of the received sound data is changed or various equalizing is performed. The information presentation unit 204 presents the received data. For example, sound data generated for output is output from a speaker unit.

  In step S7, the communication unit 201 confirms the connection state. When the connection with the connected terminal 101 is disconnected (step S7—Yes), the process proceeds to step S12. If the connection continues (No at Step S7), the process returns to Step S6 to continue receiving data.

Next, in the operations of FIGS. 3 and 4 described above, an operation example of the initial authentication registration mode that is shifted to when the terminal 101 is not registered in the connection authentication list will be described. FIG. 5 is a flowchart for explaining an operation example of the initial authentication registration mode.
The initial authentication registration mode of FIG. 5 transitions to the case where no connection authentication registration has been made for one hand terminal 101 in the connection authentication list of the remote terminal 102. Here, in step S <b> 21, the communication unit 201 transitions to the initial authentication registration mode, and is in a state where it is discovered as a connection candidate by a search from the local terminal 101.
In step S22, the communication unit 201 confirms whether there is a connection authentication request. If it is found by the hand terminal 101 and a connection authentication request is received from the hand terminal 101 (step S22—Yes), the process proceeds to step S23. If there is no connection authentication request from the local terminal 101 (step S22-No), the process proceeds to step S24.

  In step S <b> 23, the communication unit 201 proceeds to a connection authentication registration procedure with the local terminal 101 that transmitted the connection authentication request, and registers the terminal that has been registered for connection authentication in the connection authentication data holding unit 202 for the first time. At this time, the registered local terminal 101 is registered as a main connection terminal. Then, the registered hand terminal 101 enters a connected state, and the process proceeds to step S5 in FIG. 3 or FIG. 4 to maintain the connection with the hand terminal 101.

  If there is no connection authentication request from the hand terminal 101 in step S22, the communication unit 201 determines the connection authentication time in step S24. If the elapsed time since the transition to the first authentication registration mode has passed a predetermined time (for example, 1 minute) (step S24-Yes), the first authentication registration mode is terminated, and step S12 in FIG. 3 or FIG. To go to standby mode. If the predetermined time has not elapsed in step S24 (step S24-No), the process returns to step S21.

Next, in the operations of FIGS. 3 and 4, an example of operation in the new authentication registration mode that shifts when the terminal 101 is registered in the connection authentication list and the connection authentication permission flag is ON will be described. FIG. 6 is a flowchart for explaining an operation example of the new authentication registration mode.
The new authentication registration mode in FIG. 6 transitions when the connection authentication permission flag is ON in step S2 in FIGS. Here, in step S <b> 31, the communication unit 201 shifts to the new authentication registration mode and enters a state where it is discovered as a connection candidate by a search from the local terminal 101.
In step S32, the communication unit 201 confirms the presence / absence of a connection authentication request. If it is found by the local terminal 101 and a connection authentication request is received from the local terminal 101 (step S32—Yes), the process proceeds to step S33. If there is no connection authentication request from the local terminal 101 (step S32—No), the process proceeds to step S34.

  In step S <b> 33, the communication unit 201 proceeds to a connection authentication registration procedure with the local terminal 101 that transmitted the connection authentication request, and newly registers the local terminal 101 that has been registered for connection authentication in the connection authentication data holding unit 202. At this time, the registered local terminal 101 is connected as a main connection terminal or a sub connection terminal. Then, the registered hand terminal 101 enters a connected state, and the process proceeds to step S5 in FIG. 3 or FIG. 4 to maintain the connection between the hand terminal 101 and the remote terminal 102.

  If there is no connection authentication request in step S32, the communication unit 201 determines the connection authentication time in step S34. If the elapsed time after shifting to the new authentication registration mode has passed a predetermined time (for example, 1 minute) (step S34-Yes), the new authentication registration mode is terminated, and step S12 of FIG. 3 or FIG. To go to standby mode. If the predetermined time has not elapsed in step S34 (step S34-No), the process returns to step S31.

Here, the main connection terminal and the sub connection terminal will be described.
The main connection terminal is a terminal used to turn on the connection authentication permission flag held in the connection authentication data holding unit 202 (change to the new authentication registration mode). The sub-connection terminal is a terminal that does not affect the connection authentication permission flag.
The number of main connection terminals is arbitrary. When the number of main connection terminals is 1, the hand terminal 101 registered for connection authentication for the first time becomes the main connection terminal, and all hand terminals 101 registered for new connection authentication thereafter are sub Connected terminal. When the number of main connection terminals is n (2 or more), the first terminal 101 for which connection authentication is registered for the first time and the (n-1) th of the new terminal 101 for which new connection authentication is registered are the main connection terminals. The connection authentication registration terminal becomes the sub connection terminal. Note that all the hand terminals 101 may be registered as main connection terminals.

Next, mode state transition in the remote terminal will be described with reference to FIG.
The main power OFF mode 11 is a state where the main power of the remote terminal 102 is turned off. When the main power supply of the remote terminal 102 is turned on, the remote terminal 102 transitions to the initialization mode 13.
Here, the initialization mode 13 is a state in which the state of the connection request from the handy terminal 101, the connection authentication list, and the connection authentication permission flag is checked, and step S2 to step S4 and step S8 to step S11 in FIG. Corresponds to the state of

When performing initial connection authentication registration or new connection authentication registration, the initialization mode 13 transitions to an authentication registration mode 14 in which authentication registration is added, and a connection request is issued when no connection is established with any local terminal 101. Transition to the waiting mode 15 to wait.
Here, the authentication registration mode 14 is a mode including the initial connection authentication registration mode and the new connection authentication registration mode, which corresponds to steps S21 to S24 in FIG. 5 and steps S31 to S34 in FIG. 6, and the standby mode is FIG. Corresponds to steps S12 to S13.
The authentication registration mode 14 transitions to the standby mode 15 when a predetermined time has elapsed.

The connectable mode 12 indicates a mode that includes an initialization mode 13, an authentication registration mode 14, and a standby mode 15. When the connection between the remote terminal 102 and any one of the terminal terminals 101 is established, the connection mode 16 Transition to.
The connection mode 16 is a state in which a connection with any one of the terminal devices 101 is established. When the connection with the connected local terminal 101 is disconnected, the mode transits to the standby mode 15.

Next, a procedure for turning on the connection authentication permission flag at the remote terminal 102 will be described. The local terminal 101 registered as the main connection terminal as described above is used to turn on the connection authentication permission flag held in the connection authentication data holding unit 202 of the remote terminal 102 and shift to the new authentication registration mode. .
Here, the connection authentication registration flag is turned OFF at the stage of transition to the authentication registration mode 14, the standby mode 15, and the connection mode 16. When the mode is shifted to the connection mode 16 and the main connection terminal and the remote terminal 102 are connected, the connection with the remote terminal 102 is disconnected from the main connection terminal side, and the main power supply of the remote terminal 102 is once turned off. The connection authentication registration flag is turned ON.

That is,
(1) Release the connection from the main connection terminal (2) Turn off the main power supply of the remote terminal 102 once and turn it on again.
Only by this procedure, the mode shifts to the new authentication registration mode. Simply operating the main power supply of the remote terminal 102 on the sealing side does not shift to the new authentication registration mode. By this connection authentication registration flag, the transition to the new authentication registration mode is limited, and the connection authentication procedure at a timing not intended by the user can be avoided as much as possible.
It should be noted that as a condition for turning on the connection authentication registration flag, a time limit may be provided for the execution of procedures (1) and (2). For example, the connection authentication registration flag may be turned ON only when the procedure (1) is performed and the procedure (2) is performed within one minute.

Next, a specific example of the connection authentication list will be described. FIG. 8 is a diagram illustrating an example of a connection authentication list recorded in the connection authentication data holding unit 202.
The connection authentication list includes “connection priority”, “terminal ID”, “main / sub flag”, and “final connection destination flag” as items. Here, the maximum number of terminals registered in the connection authentication list is arbitrary.
The “priority” determines the priority when a connection request is made from the remote terminal 102. As shown in step S10 of FIG. 3, the remote terminal 102 uses a list patrol request mode when making a connection request. Then, connection requests are made in order from the terminal with the highest priority in the connection authentication list. The priority of the connected terminal 101 is increased.

  For example, when a terminal whose terminal ID is “EEE” shown in FIG. 8 is connected to the remote terminal 102, the highest priority “4” in the sub-connection terminal is assigned, and as a result, the priority of other terminals whose priority has been removed is assigned. The priority may be lowered, and at this time, the highest priority may be assigned to “1” regardless of the main / sub flag.

The “terminal ID” is used to identify the local terminal 101 registered for connection authentication.
The “main / sub flag” is a flag for determining the above-mentioned main connection terminal and sub connection terminal.
The “final connection destination flag” indicates that the current terminal 101 that is currently connected or once disconnected is “TRUE”, and other terminals are “FALSE”. The terminal 101 that is finally connected indicates a terminal for which connection is requested in step S3 of FIG.
For example, the remote terminal 102 may be newly provided with a reset button, and the connection authentication list may be reset when the user presses the reset button.

  With the above configuration, the data processing terminal installed at a location out of the reach of the user and eliminating the transition to the connection authentication procedure unintended by the user as much as possible, and executed by the data processing terminal connected to the user terminal and the data processing terminal. A data processing method can be provided.

(Second Embodiment)
A data processing terminal that is installed at a location out of the reach of the user by the configuration in the first embodiment and is wirelessly connected to the user terminal while eliminating as much as possible the transition to a connection authentication procedure unintended by the user, and A data processing method can be provided.
In the configuration of the first embodiment, the hand terminal 101 registered as the main connection terminal is used to turn on the connection authentication permission flag and shift to the new authentication registration mode. Here, for example, when all the hand terminals 101 registered as the main connection terminals are lost, it becomes impossible to shift to the new authentication registration mode.

Therefore, in this embodiment, it is possible to newly register a main connection terminal.
In the present embodiment, the remote terminal 102 has a connection history list as shown in FIG. 9 in addition to the connection authentication list shown in FIG. 8 of the first embodiment.
The connection history list holds the history of the local terminal 101 connected to the remote terminal 102. This connection history list is updated when the connection is established (when the connection mode is entered).

The operation flow in this embodiment is as shown in FIG.
In step S41 in FIG. 10, the communication unit 201 of the remote terminal 102 checks whether or not the connection mode has been changed. When the connection mode is changed (step S41-Yes), the process proceeds to step S42. When it does not change to the connection mode (step S41-No), it waits for the change to the connection mode.
When transitioning to the connection mode, in step S42, the communication unit 201 updates the connection history list shown in FIG. Here, the latest terminal ID of the connection destination is registered in the connection history number 1, and the connection history is lowered in order.

In step S43, an arbitrary threshold value (“3” in the example of FIG. 8) is set in the connection history list, and the connection history of the same terminal ID is the threshold number by referring to the connection history for the threshold number from the latest connection history. If the minute number has been registered (step S43-Yes), the process proceeds to step S44. Otherwise (step S43-No), this process ends.
For example, in the example of the connection history list shown in FIG. 9, when the threshold value is 3, the terminal ID “EEE” is registered in the latest three connection histories. Therefore, in this case, step S43 becomes Yes, and the process proceeds to step S44. In the example of the connection history list in FIG. 9, it is expressed that up to seven connection histories are held, but the number of connections held in the connection history list may be the threshold number.

In step S44, the communication unit 201 updates the main connection terminal.
In the connection authentication list of FIG. 8, the terminal having the terminal ID “EEE” is a sub-connection terminal, but is promoted to the main connection terminal by the processes of FIGS. At this time, when the maximum number of main connection terminals is 3, the local terminal 101 having the terminal ID “CCC” having the lowest connection priority among the main connection terminals is lowered to the sub connection terminal having the priority “4”. It is done. The local terminal 101 having the terminal ID “EEE” is registered as the main connection terminal having the connection priority “1”.

The local terminals 101 having the connection IDs “AAA” and “BBB” have the connection priority “2” and the connection priority “3”, respectively. Further, the hand terminal 101 having the terminal ID “DDD” which is the sub-connection terminal remains the sub-connection terminal, and the connection priority is “5”. The registration contents of the terminal 101 having the terminal IDs “FFF” and “GGG” that are sub-connection terminals and have low connection priority are not changed.
In addition, when said threshold value is set to "1", it becomes a structure registered as a main connection terminal in order of the newest connection destination. With the above configuration, the local terminal 101 registered in the main connection terminal can be switched.

(Third embodiment)
In the configuration of the second embodiment, the main connection terminal can be updated. In this case, in order to update the main connection terminal, it is necessary to connect any local terminal 101 to the remote terminal 102 continuously for the number of times set as the threshold. If you allow the connection of your local terminal, the update procedure will start over from the beginning. In the present embodiment, in view of the above, it is possible to update the main connection terminal without continuously connecting the same local terminal.
FIG. 11 shows a “connection authentication list” in the present embodiment, which is an extended example of the “connection authentication list” in the first embodiment. This connection authentication list has “connection score” in addition to “priority”, “terminal ID”, “main / sub flag”, and “final connection destination flag”.

The “connection score” indicates a value obtained by counting the number of times the hand terminal 101 is connected to the remote terminal 102, and is used for updating the registration of the main connection terminal. The remote terminal 102 performs a process of updating the main connection terminal when the connection score exceeds an arbitrary threshold (for example, 5). The process flow will be described with reference to FIG.
In step S51, the communication unit 201 of the remote terminal 102 checks whether or not the connection mode has been changed. When the mode is changed to the connection mode (step S51-Yes), the process proceeds to step S52. When the mode has not changed to the connection mode (step S51-No), a transition to the connection mode is awaited.

  In step S52, the communication unit 201 updates the connection score of the connection authentication list shown in FIG. Specifically, the connection score corresponding to the terminal ID of the connected hand terminal 101 is increased by one. In step S53, when the connection score of the connected hand terminal 101 becomes equal to or greater than an arbitrary threshold (for example, 5) (S53-Yes), the process proceeds to step S54. If the connection score is not equal to or greater than the arbitrary threshold value (step S53-No), the process ends.

  In step S54, the communication unit 201 updates the main connection terminal. For example, the hand terminal 101 having the terminal ID “EEE” in FIG. 11 is a sub-connection terminal. However, in the processes of FIGS. Here, when the maximum number of main connection terminals is 3, the terminal with the terminal ID “CCC” having the lowest connection priority among the main connection terminals is lowered to the sub connection terminal with the connection priority “4”. The local terminal 101 having the terminal ID “EEE” is registered as a main connection terminal having a connection priority “1”.

  Further, the local terminals 101 having the connection IDs “AAA” and “BBB” are terminals having connection priorities “2” and “3”, respectively. The hand terminal 101 of the terminal IS [DDD], which is the sub-connection terminal, remains the sub-connection terminal, and the connection priority is “5”. Furthermore, the registration contents of the terminal 101 having the terminal IDs “FFF” and “GGG” which are sub-connection terminals and have low connection priority are not changed. Here, after updating the main connection terminal, the connection score or all connection scores of the local terminal 101 updated to the main connection terminal may be reset to zero.

Similarly to the second embodiment, when a connection history list as shown in FIG. 9 is prepared, a larger weighting score is calculated as the history is newer, and the cumulative value of this score exceeds a threshold value It may be configured to be updated. For example, as in the connection history list 20 of FIG. 13, the primary score is set so that the highest score is obtained from the newest connected terminal. In this example,
Primary score = Maximum number of connection history-(Connection history No-1)
It is set to become. Next, a weighting score is calculated for each history.
Weighted score = Primary score / Primary score total. Finally, a connection score such as the connection authentication list 21 in FIG. 13 is obtained by obtaining the total value for each terminal ID. Here, when the update threshold value for the main connection terminal is set to 0.5, the terminal with the terminal ID “EEE” is updated as the main connection terminal in the same manner as described above.
With the above configuration, the terminals registered in the main connection terminal can be switched without necessarily connecting the same terminal continuously.

(Fourth embodiment)
The configuration according to the first to third embodiments is installed at a location out of the reach of the user and wirelessly transmits to the user terminal while eliminating as much as possible the transition to the connection authentication procedure not intended by the user. A connected data processing terminal and a data processing method can be provided. If all the local terminals 101 registered as main connection terminals are broken or lost, a new main connection terminal cannot be added. Therefore, in the present embodiment, exceptionally, the hand terminal 101 can be surely registered as the main connection terminal.

  FIG. 14 is a diagram showing a configuration of a wireless connection system in the present embodiment, and shows a modification of FIG. This wireless connection system has a dedicated terminal (dedicated terminal 110) dedicated to the remote terminal 102 as a user's terminal. The dedicated terminal 110 is a remote controller for the remote terminal 102, for example, and can transmit various operation data. The operation data is, for example, volume data of music information or adjustment data of the light amount of the ceiling light.

The basic configuration of remote terminal 102 in the present embodiment is substantially the same as the configuration described in FIG. Differences in operation according to the present embodiment will be described with reference to FIGS. 3 to 6 again. FIG. 15 shows an example of a connection authentication list when the dedicated terminal 110 is provided.
As shown in FIG. 15, the dedicated terminal 110 is registered with a connection priority of “0”. Moreover, it is fixed and registered as a main connection terminal. That is, this dedicated terminal 110 is not made a sub-connection terminal by the registration procedure with the main connection terminal in the second embodiment or the third embodiment.

As a method for enabling connection of the dedicated terminal 110 with the connection priority “0” to the remote terminal 102, for example, when a product including the remote terminal 102 is shipped, a unique authentication password is assigned to each individual remote terminal 102. Only the dedicated terminal 110 that has been randomly generated and for which the password has been input can be connected.
The authentication password is printed on, for example, paper and delivered to the user together with the instruction manual of the dedicated terminal 110. The user can connect the dedicated terminal 110 and the remote terminal 102 by causing the dedicated terminal 110 to recognize the password.

The flow of operation will be described again with reference to FIG. First, in the case of the first activation, only the dedicated terminal 110 whose connection priority is “0” is registered in the connection authentication list (FIG. 15). In step S1, the communication unit 201 of the remote terminal 102 refers to the connection authentication list to determine whether or not there is a registration history. In this embodiment, as an exception, the connection priority is “0”. ”Is not included in the determination target.
That is, at the first activation, the dedicated terminal 110 is registered in the connection authentication list, but the dedicated terminal 110 is not regarded as a registration history, so step S1 is determined as “No”.

For example, even if “Yes” is determined in step S1, by setting the dedicated terminal 110 in advance as the final connection destination, “No” is set in step S2, and in any case, the new terminal Registration procedure (first authentication registration mode in FIG. 5 or new authentication registration mode in FIG. 6).
When a new terminal is not registered at the first activation, the process shifts to the standby mode shown in step S12. However, the dedicated terminal 110 can be connected by sending a connection request from the dedicated terminal 110.

After that, for example, when seven local terminals 101 are registered as new terminals, the connection authentication list is as shown in FIG. Here, when the terminal 101 having the connection priority “1” to “3” is in a failure or lost state, and the terminal 101 having the connection priority “4” to “7” is in the power OFF state. An operation example will be described.
In this situation, step S1 in FIG. 3 is “Yes”, and step S2 is also “Yes”. In step S3, since the terminal (terminal ID “EEE”) whose connection priority is “5”, which is the final connection destination, is powered off, step S4 becomes “No” because the connection is unsuccessful. .

If it is in the list patrol request mode in step S8, a connection request is sent to the remaining list in the connection authentication list in step S9.
At this time, in the present embodiment, it is preferable that the dedicated terminal 110 whose connection priority is “0” is not included in the determination target. If the dedicated terminal 110 is included in the determination, the connection is always established as long as the dedicated terminal 110 is powered on. Therefore, when the main power is turned on next time, “No” is obtained in step S2, and connection authentication from an unintended user is allowed. However, if the dedicated terminal 110 is turned off, the above-described state does not occur, and the dedicated terminal 110 may be included in the determination. Accordingly, the dedicated terminal 110 is continuously registered as the main connection terminal.

  Further, a case will be described in which a weighting score that is larger as the history is newer is calculated as illustrated in FIG. 13 and the main connection terminal is updated when the cumulative value of the score exceeds a threshold value. In the present embodiment, the dedicated terminal 110 is fixedly registered as the main connection terminal in the connection authentication list. Here, when the update threshold value for the main connection terminal is 0.5, the terminal with the terminal ID “EEE” is updated as the main connection terminal. At this time, the connection priority of the terminal with the terminal ID “EEE” is “ 1 ”is registered. Accordingly, the dedicated terminal 110 is continuously registered as the main connection terminal.

In the situation described above, the local terminal 101 with the connection priority “1” to “3” has failed or lost, and the dedicated terminal 110 with the connection priority “0” has failed or has been lost. In such a case, the main connection terminal is lost, and a new terminal cannot be registered. However, since the dedicated terminal 110 can be registered again if the password is known as described above, for example, the dedicated terminal 110 can be dealt with by purchasing a remote controller or the like again as the dedicated terminal 110.
With the above configuration, even when all the terminals registered as the main connection terminal are broken or lost, a new connection terminal can be added.

In each of the above embodiments, the configuration in which the remote terminal 102 is applied to the ceiling light has been described as an example, but the present invention is not limited thereto. For example, the present invention can be suitably applied to a remote terminal installed on a wall or ceiling, such as a wall clock with a speaker or a ceiling fan attached to a ceiling.
Furthermore, data that can be transmitted and received is not limited to sound data, and may be various data such as image data and character data. For example, it may be data relating to an illumination pattern of a ceiling light attached to the ceiling, or data relating to image data displayed on a wall clock.
