Abstract

PURPOSE:To improve the operability of a telecontrol equipment by providing a mode setting means which performs the setting and/or cancellation of a telecontrol mode based on control information inputted via a telephone line after confirming password information. CONSTITUTION:The telecontrol equipment is called by dialing a prescribed telephone number from a telephone set at the outside, etc., by the user of the telecontrol equipment. The processor 7 of the telecontrol equipment decides a mode whether or not the telecontrol mode is set already from information stored in a memory 9, etc., corresponding to the above calling. When no telecontrol mode is set, the equipment can be set at the telecontrol mode by inputting the password number by the operator corresponding to an absence guidance processing and inputting mode set information from the telephone set at the outside.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a telecontrol device, and in particular, it is possible to arbitrarily control setting and canceling of a telecontrol mode not only by a switch provided on the device but also from a telephone outside the home. This article relates to a telecontrol device that enables

[Prior art 1] Recently, a telecontrol device has been developed that allows users to control the operation of various devices installed in a remote location such as their home, such as lighting equipment, air conditioning equipment, and other equipment, using a telephone from outside the home. has been done. In order to set such a telecontrol device to the telecontrol mode or cancel the telecontrol mode, a mode changeover switch provided on the device is normally used.

However, with such telecontrol devices, conventionally, it has been impossible to set or cancel the telecontrol mode from outside the home, or the mode has been automatically switched if the call continues for a predetermined period of time, such as about one minute. It was designed to be carried out.

[Problems to be Solved by the Invention] However, in such conventional telecontrol devices, it is impossible to set or cancel the telecontrol mode from outside the home, so it is necessary to set the telecontrol mode to the telecontrol mode before going out. If you forget, telecontrol operations may become completely impossible, or if the mode is automatically switched after ringing for a predetermined period of time, no matter who calls you, it will switch to telecontrol mode. There was an inconvenience that it had to be switched.

The purpose of the present invention was to make it possible to set and cancel the telecontrol mode arbitrarily from the outside, and to eliminate the risk of the mode being switched by an operation by an unspecified person. An object of the present invention is to provide a telecontrol device that eliminates sexual nature.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a password information confirmation means for verifying the accuracy of password information input via a telephone line, and a telecontrol mode. a control means for controlling a desired device based on control information input via a telephone line after confirming the accuracy of the password information; There is provided a telecontrol device comprising mode setting means for setting and/or canceling the telecontrol mode based on control information.

[Function] In the above configuration, when setting the device to telecontrol mode from outside or canceling the mode,
Call the telecontrol device from your phone while you are away. At this time, if the telecontrol device is already set to the telecontrol mode, when the password information is input, the accuracy of the password information is confirmed by the password information verification means. If the password information is accurate, the control means controls the desired device based on control information input together with the password information or subsequently to the password information. On the other hand, if the telecontrol device is not yet in the telecontrol mode when the telecontrol device is called, the password information is input after a certain paging time has elapsed. If this password information is determined to be accurate by the password information verification means, the mode setting means sets the telecontrol mode based on the control information input together with the password information or subsequently to the password information. and/or cancel.

[Example] Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 schematically shows a telecontrol device according to an embodiment of the present invention. The device shown in the figure is a telephone subscriber line 1.
a network controller 3 connected to the network controller 3; an interface circuit 5 connected to the network controller 3;
, a processor 7 connected to the interface circuit 5,
A memory 9, a speech synthesis circuit 11, an input/output crab unit 13, and a mode selector switch 1 are connected to the processor 7, respectively.
5. A controlled device 19 is connected to the input/output crab unit 13 via a multi-drop wiring 17.

Note that 21 is a telephone connected to the network controller 3. Further, the network controller 3 includes a modem and the like.

Next, the operation of the telecontrol device having the above configuration will be explained with reference to the flowchart shown in FIG. A user of the telecontrol device calls the telecontrol device by dialing a predetermined telephone number from a telephone set while away from home.

In response to this call, processor 7 of the telecontrol device determines from information stored in memory 9 or the like whether the device is already set in telecontrol mode. If the device is already set to telecontrol mode, the user will be given an absence guidance. This absence guidance may be, for example, by transmitting some tone, or by transmitting some message by the voice synthesis circuit 11. When the user enters the password after receiving the absence guidance, the processor 7 determines whether the password is accurate based on information stored in the memory 9 in advance. If the password is correct, the device enters the telecontrol process. In the telecontrol processing, desired equipment is controlled in accordance with control information input by a user using a telephone dial, for example, such as turning on and off a lighting fixture or starting and stopping an air conditioner. Further, if the password is not input even after a predetermined period of time has elapsed after performing the absentee guidance process, the line is disconnected, etc., and the process is terminated.

If the device is not set to telecontrol mode when the user calls the telecontrol device, the device will wait for a predetermined ring time, e.g. 30 seconds, before the user hangs up. If not, the same absence guidance process as described above is performed. When the user inputs a password in response to this absence guidance process, the processor 7 determines the accuracy of the password. If the PIN is correct and the user then enters the mode setting information from the out-of-home telephone, the device is set to telecontrol mode. This telecontrol mode is set, for example, by setting a mode flag in the memory 9. After the telecontrol mode is set in this way, the same telecontrol processing as described above becomes possible, and the desired equipment is remotely controlled by the control information input by the user from the telephone.

In addition, in the above description, we have explained the case where the device is set to telecontrol mode from a telephone or the like while away from home.
The present invention is not limited to this, and it is also possible to cancel the telecontrol mode remotely, for example. or,
It is also possible to configure the system so that after setting the telecontrol mode and remotely controlling a desired device from a telephone or the like outside the home, the telecontrol mode can be canceled again if necessary. In addition, if the entered PIN number is not accurate, such as when it is different from the one registered in advance, we will allow you to re-enter it twice, for example, and if you do not enter the correct number in the end, you will be forced to do so. You can perform processing such as automatically cutting off the line.

[Effects of the Invention] As described above, according to the present invention, in a device having a telecontrol function, the telecontrol function can be switched not only by operating a mode changeover switch provided on the device, but also by using a telephone outside the home, etc. The telecontrol device can be operated at will, which greatly improves the operability of the telecontrol device. Furthermore, the risk of inadvertent mode switching due to operation by an unspecified person is reduced, making it possible to improve the safety and reliability of device control.
