(First embodiment)
FIG. 1 is a configuration diagram of a remote control device according to a first embodiment of the present invention, FIG. 2 is a configuration diagram of a remote control system configured using the remote control device, and FIG. 3 is a configuration of a line interface of the remote control device. FIG. 4 is an operation flowchart of the remote control device.
[0021]
As shown in FIG. 2, the remote control device 1 of the first embodiment is provided in a house, for example, and remotely controls various devices 2 in the house according to a remote operation signal received from the outside through the telephone line L. Therefore, a simple remote control system is configured together with the various devices 2 and the telephone 3.
[0022]
In the example of FIG. 2, the device 2 has a receiving unit 210, the lighting device 21 that operates according to the control signal received by the receiving unit 210, and the receiving unit 220, and the control received by the receiving unit 220. An air conditioner 22 that operates according to the signal is provided. The telephone 3 is a telephone with an answering machine function that records an answering message when the number of callings reaches a predetermined number of calls set in advance when the answering machine is set.
[0023]
As shown in FIG. 1, the remote control device 1 includes a power supply unit 10 that rectifies and smoothes commercial power and supplies the power to each unit, and an operation unit 11 that includes various operation and setting switches. In addition to a display unit 12 for operating state display, which includes an LED (light emitting diode) or a liquid crystal display panel, a line interface 13, a functional chip 15, a controller 16, and an infrared transmission unit 17 are provided. Is provided.
[0024]
The line interface 13 is for receiving a remote operation signal for the device 2 from the outside and for delivering voice guidance from a function chip 15 described later to the outside. As shown in FIG. Yes. That is, input terminals L1 and L2 for connection to the telephone line L, telephone connection terminals T1 and T2 connected in parallel to the telephone line L and connected to the telephone 3, and a call for monitoring the telephone line L and detecting a call signal A detection circuit 130, a current detection circuit (polarity inverting circuit) 131 that monitors the telephone line L to detect the off-hook of the telephone 3, a normally-open contact relay 132 that closes at the time of off-hook, and a signal for transmission only The line transformer 133 is configured. The call detection circuit 130 detects a call from the telephone line L by measuring the pulse of the call signal. The current detection circuit 131 measures the current flowing through the telephone line L to detect whether the telephone line L is off-hook and in use. When it is necessary to generate a dial pulse after off-hook, the dial pulse is generated by turning on and off the contact of the relay 132.
[0025]
Returning to FIG. 1, the function chip 15 performs dial control, transmission of a predetermined voice signal to the telephone line L, conversion of a tone signal from the telephone line L into a code, and the like. Specifically, a tone signal by DTMF to the telephone line L is generated by DTMF (Dial Tone Multi Frequency) encoding, a predetermined voice signal to the telephone line L is generated by voice synthesis (IC), and also by a DTMF decoder. The DTMF signal from the telephone line L is decoded.
[0026]
The controller 16 includes a CPU and a storage device, and executes processing such as control of the entire remote control system.
[0027]
The storage device includes, for example, a nonvolatile semiconductor memory in addition to a volatile semiconductor memory, and stores various control commands included in each control signal for each device 2 in advance in the same manner as a so-called universal remote controller. In addition, control commands registered later by the user can be stored. Each control command is stored in association with an (operation) code obtained from DTMF included in a remote operation signal from the outside via the function chip 15. Furthermore, the storage device stores a password that is registered in advance by the user and compared with information obtained from DTMF included in an external remote control signal. The storage device does not have to store the same control commands as those of the universal remote controller in advance, and may be any storage device that stores at least various control commands included in each control signal for each device 2 in advance. The control command may or may not be the same code as the operation command.
[0028]
The process of the controller 16 that is a feature of the first embodiment is a control for transmitting a control signal including a corresponding control command to the device 2 via the infrared transmission unit 17 in accordance with an operation input of the operation unit 11. Executed. Thereby, the lighting fixture 21 can be turned on or off, the operation of the air conditioner 22 can be executed or stopped, and the remote control device 1 is used like a universal remote control (or a remote control attached to those devices 2). can do.
[0029]
Further, the telephone line L is monitored via the function chip 15 and the line interface 13, and when the ringing signal is received from the telephone line L, it waits until the telephone 3 goes off-hook first, and the telephone 3 is off-hooked by the current detection circuit 131. After this is detected, the control is performed to close the relay 132 and off-hook itself.
[0030]
Here, it will be further described that the telephone 3 waits until it goes off-hook first. In the first embodiment, the number of calls for the answering record set in the telephone 3 is larger and the answering function of the telephone 3 is canceled. It holds the number of waiting limit calls set so that the number of calls required for the off-hook that the user in the house picks up the handset of the telephone 3 is larger. As a result, normally, when the user is absent, the telephone set 3 with the answering record function goes off-hook first, and when there is a user in the house, the user first takes off the phone and goes off-hook. On the other hand, when the remote control device 1 goes off-hook first, it is a case where the user has forgotten to set the answering machine, and the number of calls obtained from the call detection circuit 130 reaches the above-mentioned waiting limit number of calls. Such as the case.
[0031]
In addition, after going off-hook, without waiting for the voice code to enter the security code, it waits for the security code to be hidden as if it is hidden in the background. A process for performing authentication is executed. Here, as a remote operation start procedure, it is determined that the password is input after the recording start time of the telephone 3 in order to prevent the voice guidance and the remote operation input during the absence recording operation of the telephone 3 from batting. Keep it.
[0032]
Also, at the time of authentication, if the correct authentication result of the PIN is not obtained within a predetermined time, the authentication is stopped, and if the correct authentication result of the PIN is not obtained even if the authentication is repeated a predetermined number of times, Processing to stop authentication and go on-hook is executed.
[0033]
When a correct authentication result of the personal identification number is obtained, a remote operation input voice guidance is played, and a process of receiving a remote operation signal from the communication partner is executed after this voice guidance or during silence during that time. Here, when there is no sound during the voice guidance, a DTMF can be transmitted, for example, at a paragraph or sentence break. Note that the voice guidance does not necessarily have to be played. For example, the voice guidance may be played when a guidance request command is received from a remote operation signal.
[0034]
Further, in response to a remote operation signal received through the line interface 13, a control signal including a control command corresponding to the operation command included in the remote operation signal is transmitted to the device 2 through the infrared transmission unit 17 a plurality of times. Control is executed.
[0035]
Furthermore, when a control signal for operation execution is transmitted to the air conditioner 22 a plurality of times via the infrared transmitter 17 in response to a remote operation signal received through the line interface 13, in order to prevent forgetting to stop the operation of the air conditioner 22. After a predetermined time (several hours) has elapsed from the time when the operation execution control signal is transmitted, a process of transmitting the operation stop control signal to the air conditioner 22 a plurality of times is executed.
[0036]
As a feature of the first embodiment, the infrared transmission unit 17 is configured by, for example, an infrared LED so as to transmit a control signal to the device 2 as an infrared signal. Thus, as shown in the example of FIG. 2, if each receiving unit of the device 2 receives the control signal by infrared rays, the remote control system is configured together with the remote control device 1 of the first embodiment. Can do.
[0037]
Further, by storing each part of the remote control device 1 configured as described above in a single container, a telephone line L and a telephone are connected to the input terminals L1 and L2 and the telephone connection terminals T1 and T2, respectively. A remote control system can be constructed very simply by connecting 3.
[0038]
Next, an operation related to call monitoring by the remote control device 1 which is a feature of the first embodiment will be described. It is confirmed whether or not a call signal is detected by the call detection circuit 130 (S1 in FIG. 4). If not detected (NO in S1), the process returns, executes another process, and enters step S1 again. .
[0039]
If a call signal is detected (YES in S1), it is confirmed whether or not an off-hook has been detected by the current detection circuit 131 (S2). If detected (YES in S2), the process proceeds to step S3. If not detected (NO in S2), it is confirmed whether or not the number of calls reaches the waiting limit number of calls (S4). If not (NO in S4), the process returns to step S2, and if reached (YES in S4), the process proceeds to step S3.
[0040]
In step S3, the relay 132 is closed to go off-hook, a timer is started (S5), and input of a personal identification number is awaited in the background. That is, it is confirmed whether or not a predetermined time (for example, 30 seconds) has elapsed since the timer start time (S6). If it has elapsed (YES in S6), the process proceeds to step S13, but if it has not elapsed (NO in S6) ), It is confirmed whether or not a password has been entered (S7).
[0041]
If the code number is not input (NO in S7), the process returns to step S6. If the code number is input (YES in S7), authentication is performed to check whether the authentication is OK (S8). ).
[0042]
If the authentication is not OK (NO in S8), the number of authentication failures is counted up (S9). At this time, in order to notify the user that the authentication has failed, it is desirable to send a message to that effect by voice guidance. Subsequently, it is confirmed whether or not the count value is equal to or greater than a predetermined value (S10). If the count value is not equal to or greater than the predetermined value (NO in S10), the process returns to step S6. If the count value is equal to or greater than the predetermined value (YES in S10), the process proceeds to step S13.
[0043]
If the authentication is OK (YES in S8), it is confirmed whether or not an operation command obtained from the remote operation signal is received while voice guidance for remote operation input is played (S11). Here, the process of receiving the operation command is executed after the voice guidance of the remote operation input that is flown after a predetermined time (for example, about 5 seconds) has passed since the authentication OK, or when there is no sound during that time. If the operating user is not used to remote operation, the user can proceed with the remote operation while listening to the voice guidance. If the user is used to remote operation, the user can proceed quickly without listening to the entire voice guidance. And can save on call charges.
[0044]
If no operation command is received (NO in S11), the process returns to step S11. At this time, it is desirable to monitor whether or not the communication partner has disconnected the telephone line, and when the telephone line is disconnected, it is desirable to proceed to step S13. On the other hand, if an operation command is received (YES in S11), a process of transmitting a control signal including a control command corresponding to the operation command to the device 2 a plurality of times via the infrared transmission unit 17 is executed (S12). Here, unlike the operation using the remote controller, the operation of the device 2 cannot be confirmed after the remote operation. However, the device 2 is reliably operated by the remote operation by transmitting the control signal a plurality of times in step S12. Can do. Specifically, if the control command corresponding to the operation command is a lighting command for the lighting fixture 21, the lighting command is transmitted, and the lighting command is transmitted again after a predetermined time. Similarly, the turn-off and dimming commands are transmitted multiple times. Further, if the control command is a command for the air conditioner 22, the command is similarly transmitted a plurality of times. Furthermore, also when both the lighting fixture 21 and the air conditioner 22 are operated remotely, the command with respect to each is transmitted several times.
[0045]
After step S12 or when proceeding to step S13, the relay 132 is opened and on-hook is performed, and then the process returns. Here, even if the telephone 3 is on-hook when it is talking, the telephone line is not cut off because the telephone 3 is off-hook.
[0046]
In the first embodiment, the remote control device is configured to transmit a control signal as an infrared signal, and the receiver of the device is configured to receive the control signal as an infrared signal. The control signal may be transmitted by radio waves, and the receiving unit of the device may be configured to receive the control signal by radio waves.

Therefore, in the second embodiment, a plurality of infrared rays are emitted in each direction so that the infrared rays emitted from the infrared transmission unit 17A are received by the receiving units 210 and 220 of both the lighting fixture 21 and the air conditioner 22. The infrared LED 170 constitutes the infrared transmitter 17A.
[0051]
In addition, as a second feature, the plurality of infrared LEDs 170 are operated in order according to directions. Thereby, infrared rays in different directions can be prevented from colliding with each other, reliable transmission is possible, and the number of infrared LEDs 170 that simultaneously transmit infrared rays is reduced, so that the power supply capacity of the power supply unit 10 can be reduced. Can do. In the example of FIG. 5, infrared rays are emitted in three directions, and two infrared LEDs 170 are provided in each direction.
[0052]
(Third embodiment)
FIG. 6 is an explanatory diagram of an infrared transmitter in the remote control device according to the third embodiment of the present invention.
[0053]
As shown in FIG. 6, the remote control device of the third embodiment differs from the remote control device of the first or second embodiment in that the telephone 3 is connected from the telephone line L in addition to the configuration of the line interface 13. A normally closed contact relay 135 for disconnecting is provided to constitute the line interface 13B, and the contact of the relay 135 is opened when a correct authentication result of the password is obtained, and the contact of the relay 135 is set when the remote control device is on-hook. Is returned to the closed state.
[0054]
Usually, since the contact of the relay 132 is open and the contact of the relay 135 is closed, the telephone 3 can be used in the same manner as in the prior art. When the ringing signal is received, the telephone 3 is first off-hooked as in the first embodiment, so that the telephone 3 can be used in the same manner as in the prior art.
[0055]
In the third embodiment, as a difference from the first or second embodiment, when a correct authentication result of the personal identification number is obtained, the incoming call is regarded as being for the remote control device, and the contact of the relay 135 The telephone 3 is disconnected from the telephone line L by opening. As a result, it is possible to avoid listening to unnecessary voice guidance, DTMF sound, etc. when the telephone 3 is playing back recorded messages. Further, since the contact point of the relay 135 is returned to the closed state when the remote control device is on-hook, the telephone 3 is returned to a state where it can be used as in the conventional case.
[0056]
