DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device for remotely controlling various electronic devices in a home from the outside, a remote control system using the device, and a remote control method.

[0002]

2. Description of the Related Art In recent years, various types of electronic devices in the home, such as video equipment such as a television receiver and a video tape recorder, audio equipment, and air conditioning equipment, have been transferred from fixed places such as public telephones or mobile phones. A system for remotely controlling a wireless terminal capable of mobile communication via a telephone line has been developed. As such a remote control system, for example, Japanese Patent Application Laid-Open Publication No. Hei 7-131542 discloses a method of displaying and operating a telecontrol system.

In a conventional remote control system, as typified by this telecontrol system, a plurality of electronic devices are directly controlled one by one while checking control information managed by a home bus system on an external terminal side. Is used.

[0004]

In this case, the corresponding control information is downloaded from the home bus system to the terminal, the operation content of the device is set, and the operation instruction is transmitted to the home bus system. It is necessary to perform such control operations individually for each device to be controlled. Therefore, it is necessary to always connect the external terminal to the home bus system during the control operation.
As the number of electronic devices to be controlled increases, the communication time increases proportionately.

[0005] When the communication time becomes longer as described above, remote control using a mobile communication terminal such as a mobile phone not only increases the communication cost but also increases the communication cost.
Problems such as the remote control being interrupted halfway due to the deterioration of the communication state and the like are likely to occur. For example, if the radio wave from the base station moves to a weak place or if strong fading that adversely affects the communication state occurs, communication for remote control is temporarily interrupted, and further, such fading occurs. If it occurs for a long time,
Since the line is disconnected, remote control cannot be performed and the operation ends.

[0006] When such a situation occurs, move to a place where the radio wave from the base station becomes strong again or wait until strong fading disappears, and then connect again for communication to control the electronic equipment. You have to do it one by one from the beginning. In remote control in such a state,
There is also a problem that an uneasy element such as "Is it possible to control correctly?" In communication during movement, fading usually occurs almost always, and the probability that such fading that affects the communication state increases as the communication time becomes longer increases.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and it is possible to shorten the communication time required for remote control, and realize low-cost and highly reliable remote control. An object of the present invention is to provide a communication terminal device, a remote control system using the same, and a remote control method.

[0008]

Means for storing control information necessary for setting the operation of the plurality of electronic devices, and operation content setting means for setting operation content to be executed by each of the electronic devices to be controlled using the control information When,
After setting the operation content of each electronic device to be controlled by the operation content setting means, the electronic device is communicatively connected to a control device connecting the plurality of electronic devices and the network via the network, and Communication means for collectively transmitting operation setting information corresponding to the device.

In this communication terminal device, control information necessary for setting the operation of each of a plurality of electronic devices is stored in advance, and by using the control information, the connection state can be reduced before the actual communication is performed. Thus, a setting process for determining the operation content of each electronic device to be controlled can be performed. After this setting processing, communication connection with the control device is performed, and operation setting information corresponding to the electronic device to be controlled is transmitted to the control device in a lump. Therefore, the communication time can be reduced as compared with the conventional system in which the control of the electronic devices is controlled one by one while the control information managed by the home bus system is checked on the terminal side.
In addition, since the operation setting information is transmitted collectively as described above, even if the number of electronic devices to be controlled increases, the amount of transmitted information only needs to increase slightly, and is proportional to the number of electronic devices to be controlled. Therefore, there is no problem that the communication time increases.

A communication terminal connected to the control device for transmitting a status acquisition request for confirming the status of all of the plurality of electronic devices to the control device; Preferably, the apparatus further comprises means for receiving status information of each of the plurality of electronic devices transmitted collectively from the control device in response to the status information, and displaying the received status information on a screen. This makes it possible to immediately check the latest operation state of each of the electronic devices to be controlled without individually specifying and communicating with each of the electronic devices.

[0011] Further, a means for holding a password required for communication connection with the control device in the communication terminal device, and the stored password and an input password from a user before communication connection with the control device. It is preferable that the apparatus further comprises means for executing an authentication process by using the above, and means for transmitting an authenticated password to the control device when connecting to the control device via a network.

As described above, the password authentication is performed before the communication connection with the control device and the authenticated password is transmitted without inputting the password at the time of network connection, thereby further shortening the communication time. Becomes possible.

Execute the program. In the next step S2, the user is prompted to input a password, and a password for connecting to the home bus control terminal 4 is input from the user. In step 3, the input password is checked against the password stored in the password storage unit 24 in the RAM 13 of the portable information terminal 1 to determine whether the user is a valid user who can connect to the home bus control terminal 4. An authentication process is performed to check whether or not this is the case. If the passwords match, the process proceeds to the next step S4, and if they do not match, the process proceeds to step S1.
The process proceeds to step S9, and after displaying an error message, ends in step S20.

In step S4, an operation is performed as to whether the desired setting (1) is to be performed for the electronic device to be remotely controlled, or whether the setting state of the device to be remotely controlled is to be confirmed (2) or to be terminated (3). The selection of the mode is performed according to the input from the user.

When the setting (1) is selected from the tablet 4 of the portable information terminal 1, the process proceeds to the next step S5, and when the confirmation (2) is selected, the process proceeds to step S15. End (3)
If is selected, the process proceeds to step S21 to disconnect the line, and ends in step S23. If the line is not connected, the process immediately ends without doing anything.

Here, the case where the setting (1) is executed will be described first.

When the setting (1) is executed, the next step S
The process moves to 5. In step S5, information on the device to be controlled, for example, control information on the TV 5, VTR 6, lighting 7, air conditioner 8, and the like is read from the control information storage unit 23 in the RAM 13 and displayed on the tablet 14. When the display is completed, an operation state setting process is performed in the next step S6. Here, the user inputs all the settings of the device to be set from the tablet 14. When the setting is completed, the input operation setting information is stored in the setting information storage unit 22 in the RAM 13 in the next step S7. When the saving is completed, the process proceeds to the next step S8.

In step S8, a connection is made to the home bus control terminal 4. The home bus control terminal 4 performs a line connection process in step S101 in the flowchart of FIG. When the line connection is completed, the portable information terminal 4 proceeds to the next step S9, and the home bus control terminal 4 proceeds to the step S1.
Go to 02.

In step S9, the RA of portable information terminal 1
The password is read from the password storage unit 24 in M13, and the password is transmitted from the portable information terminal 1 to the home bus control terminal 4. Normally, the user inputs a password for connecting to the home bus control terminal 4 here. However, in this embodiment, since the authentication processing has already been completed in steps S2 and S3, the password input is performed. Instead, the password in the password storage unit 24 is immediately transmitted to the home bus control terminal 4. Of course, the input password from the user may be transmitted.

In the home bus control terminal 4, step S1
02, the password from the portable information terminal 1 is received, and in the next step S103, the RAM 3 in the home bus control terminal 4
3 is compared with the received password. If the passwords match, the connection permission information is transmitted to the portable information terminal 1 through the external I / F unit 34 in the next step S104. If they do not match, the process proceeds to step S119, and the external I / F unit 34
The connection non-permission information is transmitted to the portable information terminal 1 through the, and the line is disconnected in step S120.

When the transmission of the connection permission information is completed in step S104, the process proceeds to the next step S105. The portable information terminal 1 receives the connection permission information in step S10, and when this is completed, in the next step S11, the setting information storage unit 2
The operation setting information corresponding to all the devices stored in the device 2 is read out and transmitted to the home bus control terminal 4 collectively as remote control information. When the transmission is completed, the process proceeds to the next step S12.

In the home bus control terminal 4, step S10
5 receives information from the portable information terminal 1 and sets (1)
The confirmation (2) or the end (3) is determined. If the information from the portable information terminal 1 is set (1), the next step S
The process proceeds to 106, and if it is confirmation (2), step S1

When the information of the setting (1) is received from the portable information terminal 1 in step S105, the remote control information including the operation setting information of each control target device is received in step S106. S10
Proceed to 7. In step S107, all the received operation setting information is temporarily stored in the setting information storage unit 42 in the RAM 33. When the saving is completed, the operation setting information is read from the setting information storage section 42 in the next step S108, and the corresponding setting contents are transmitted to the electronic device specified by the operation setting information. For example, when turning on the power of the TV 5 and the air conditioner 8, first, the T
Operation setting information for instructing V5 to turn on the power is transmitted. When the transmission is completed, the process proceeds to the next step S109.

In the TV 5, the power is turned on based on the operation setting information. When the setting is completed, the result of the setting “power ON” is transmitted to the home bus control terminal 4. In step S109, the electronic device receives the setting result transmitted from (here, TV5). When the reception is completed, the setting result is stored in the state storage unit 41 in step S110. In step S111, it is checked whether there is any unset device.
Repeat from 08 in the same way. For example, since the setting of the air conditioner 8 has not been performed here, the process returns to step S108 again and performs the same processing.

When all the settings in the operation setting information are completed, the setting state information of all the devices in the state storage section 41 is transmitted to the portable information terminal 1 in a lump in the next step S112. The portable information terminal 1 receives the setting state information in step S12.

When the reception is completed, the next step S13
Then, the received state information is stored in the state storage unit 21 in the RAM 13.
In the next step S14, the data stored in the state storage unit 21 in the RAM 13 is displayed on the tablet 14 as a setting state.

When the display is completed, the process returns to step S4 again, and the setting (1), the confirmation (2), or the end (3) is selected again. When setting (1) is performed, the process returns to step S5, and the same processing is performed.
When performing step S15, the process proceeds to step S15. End (3)
If is selected, the line is disconnected in step S20, and the process ends in step S21. Home bus control terminal 4
Then, the process proceeds to step S120 to perform a line disconnection process, and ends the process in step S121.

Next, the case of confirming the setting state of the electronic equipment (2) will be described.

When confirmation (2) is selected in step S4 on the portable information terminal 1, the process proceeds to the next step S15. In steps S15 to S17, the same processing as in steps S8 to S10 described above is performed. When the connection permission information is received in step S17, in the next step S18, the device information is read from the device information table 25 of the control information storage unit 23 in the RAM 13, and the state confirmation information is transmitted. When the transmission is completed, the process proceeds to the next step S12. Subsequent steps are the same as when setting (1) is performed. The home bus control terminal 4 sends the status confirmation information to the step S105.
, The process proceeds to step S113. Step S1
In step 13, the state confirmation information is received, and the next step S114
To save the status confirmation information in the setting information storage unit 42. In the next step S115, the setting states of all the electronic devices stored in the setting information storage unit 42 are checked, and the current state is obtained from each electronic device. For example, T
When the V5, the VTR 6, the lighting 7, and the air conditioner 8 are connected, first, the current setting state of the TV 5 is checked. T
The state confirmation information is transmitted to the V5, and the TV 5 receiving this transmits the current state as the setting information. Step S11
6 receives the setting information sent from the TV 5,
In the next step S117, the setting information is stored in the state storage unit.

In S118, the presence or absence of an unconfirmed device is confirmed, and if there is an unconfirmed device, the flow proceeds to step S113 again to confirm. For example, although the setting of the TV 5 has been completed, the status of the VTR 6, the lighting 7 and the air conditioner 8 have not been checked, so the status of the VTR 6 is checked next, and further the status of the lighting 7 and the air conditioner 8 is checked and the setting is finally performed. To save the information. When the setting status check is completed for all devices, the process proceeds to step S112, and thereafter, the process is the same as when setting (1) is performed.

As described above, in the present embodiment, the control information necessary for the operation setting of all the remotely controllable electronic devices such as the TV 5, the VTR 6, the lighting 7, and the air conditioner 8 is previously stored in the portable information terminal 1. By using the control information, the setting processing for determining the operation content of each electronic device to be controlled can be performed in an unconnected state without performing actual communication. Then, after this setting process, by connecting to the home bus control terminal 4 and transmitting all operation setting information to the home bus control terminal 4 collectively, the control target is indirectly controlled via the home bus control terminal 4. All of the electronic devices can be collectively controlled. Therefore, the communication time can be greatly reduced as compared with the conventional method of directly controlling the electronic devices one by one while individually transmitting and receiving control information and the like to and from each electronic device to be controlled.

In the above description, the embodiment using the portable information terminal 1 capable of mobile communication has been described. However, a combination of a portable small portable computer and a telephone capable of mobile communication such as a mobile phone is provided. , Or a portable computer with a built-in mobile phone function, the same configuration can realize remote control with a short communication time, which is the object of the present invention. Further, the configuration of the present embodiment can be applied not only to wireless communication but also to a portable information terminal that performs wired communication using a modem or the like.
