Abstract

PURPOSE:To receive surely a significant control signal by forming a remote control number into plural number of digits and constituting a signal of the 1st digit to a remote control number fixed to a number in a pushbutton dial signal. CONSTITUTION:The area arrangement on a tape of a tape recorder 3 as a message storage means consists of a response area 11 and a message area 12, which is divided minutely into blockes 12a-12n. The number of the 1st digit among numbers of plural digits constituting a remote control number is fixed to one of the signals prepared as pushbutton dial signals so as to constitute all remote control numbers. When the number is detected at first, the operation conducted so far is stopped and a significant remote control signal transmitted from the caller side is received further by a PB signal receiver 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention provides that the press of a telephone is a button dial signal (hereinafter referred to as PB).
This invention relates to a remote control operation method for a telephone device that uses a double signal) as a remote control signal.

(Prior Art) A typical example of this type of conventional device is an answering machine. FIG. 1 shows its block diagram. In the figure, 1 is a line connection terminal, and 2 is a basic telephone unit for making and receiving calls and making phone calls. Reference numeral 3 denotes a message storage means for recording and reproducing response messages and caller's business messages, and a cassette tape recorder is usually used. 4
is a remote control signal receiving means, which is composed of a circuit for receiving a single frequency or FS signal in the audio band.

Reference numeral 5 denotes an incoming call detection means for detecting a calling signal from the station, and 6 is a relay for automatically closing a loop with the office side based on the incoming call detection output of the incoming call detection means 5. Reference numeral 7 denotes a call end detection means for detecting that the calling party has hung up the telephone handset (that is, has ended the call), and 8 is a control unit of the answering machine, which is comprised of a microprocessor or the like. - Next, an outline of its operation is shown below.

First, the owner records a message (response message) to be sent to the caller (caller) when the owner is away, and then switches the main answering machine to the answering machine using the occupancy/absence mode switch (not shown). Set it to mode. When a calling signal arrives in this state, the incoming call detection means 5 detects the calling signal and transmits it to the control section 8. The control section 8 operates the line closing relay 6 to create a loop with the station side, and reproduces and sends out the response message.

After receiving the response message, the caller confirms that the main answering machine is ready to record the caller's message, and then speaks the message he or she wants to convey. The message is stored as a message in a part of the message storage means 3 that is different from the response message storage section (for example, on a separate tape or in a separate area on the same tape). When the caller's call ends and the handset is on-hook, the signal input from terminal l to the main answering machine is either silent or a busy tone signal sent from the exchange. Otherwise, the condition is detected and transmitted to the control section 8. The control section 8 receives the end of call detection signal, restores the line closing relay 6, and opens the loop with the station side.

Next, when a call is received to the main answering machine, the same operation as described above is carried out, and message messages from an unspecified number of callers are accumulated one after another.

On the other hand, the owner of this answering machine carries a keypad that generates a remote control signal, calls the answering machine from his/her home, has it automatically answer as described above, and uses the keypad to make the telephone transmitter. acoustically coupled to a device to send out a remote control signal. When this remote control signal is sent for 3 to 5 seconds, it is received by the remote control signal receiving means 4, and the control unit 8
Then, reproduction of the message stored in the message storage means 3 is started. This playback signal is sent to the calling party's telephone, allowing the owner to listen to the message.

However, with such answering machines, even though they are called remote control, they can only be used to instruct playback of messages.
, dubbing the contents of a response message while on the go. ■Delete only unnecessary messages among the received messages. ■ Record a reply to the received business message and convey the contents to the relevant person. It is impossible to perform such operations by remote control. Therefore, the push-button dial signal (PB double signal) of the widely popular push-button dial telephone is used as a remote control signal, and the PB double signal is combined to constitute a remote control number (code), and the above-mentioned various remote control There are ways to make this possible.

A block diagram of the apparatus in this case is shown in FIG. In this figure, the same functional parts as in FIG. 1 are given the same reference numerals. Note that 9 is a PB double signal receiver, and 10 is an input means for setting a special number (so-called password) for entering the remote control mode.

With this type of device configuration, in addition to the password, a remote control number that specifies various operations of this device is set up. By doing so, various operations can be performed.

However, since the PB signal receiver 9 is a signal in the PB double signal voice frequency band, it is necessary to prevent the PB signal receiver 9 from malfunctioning due to the voice.
The configuration makes it difficult to receive the PB multiple signal if the PB multiple signal is superimposed. In other words, the configuration is such that when the S/N ratio is small, no signal is received.

Therefore, when using the PB double signal as a remote control signal, the PB double signal will not be received even if the PB double signal is sent during the period when the response message is being sent from this device or during the period when the business message is being reproduced and sent by remote control. This results in extremely poor operability.

In addition, when increasing the number of operations that can be performed by remote control, it is necessary to configure the remote control number with multiple digits of the PB double signal. There is a risk that the signal frequency component will be erroneously received as a remote control signal, causing the device to malfunction.

On the other hand, some of the telephone systems that currently input data using PB double signals include train seat reservation systems and systems for checking bank balances, but these systems do not accept voice messages sent from centers. After listening, P.
A method is adopted in which data is sent using a B-fold signal, and the next voice message is sent from the center in response.1 Therefore, even if such a method is applied to the above-mentioned answering machine, the owner There is a drawback in terms of operability that it is not possible to proceed to remote control operation until all response messages set by the user have been heard.

(Object of the Invention) The present invention aims to eliminate these conventional drawbacks, and specifically, during the period when the telephone device is transmitting a voice signal, specifically during the sending of a response message or the reproduction of a business message by remote control. Among these, the purpose is to ensure normal reception of PR multiplexed signals without erroneous reception.

(Structure of the Invention) For the above purpose, the present invention fixes the first digit of each of the multiple digit numbers constituting the remote control number to one of the signals prepared as a push button dial signal. Configure all remote control numbers using It is intended to be received.

(Embodiment) An embodiment of the remote control operation method of the present invention will be described below using an answering machine shown in FIG. 2, and its remote control number structure and operation side.

FIG. 3 shows an example of area arrangement on a tape when a cheap record is used as a message storage means. In the figure, No. 1 is a part where the line and loop are automatically closed in response to an incoming call, and then a message to be sent to the calling party is recorded, and is called a response area. 12
This is the 86-minute area where messages sent from the 11th generation and other people are recorded, and is called the message area. Also, 12
A to 12n are parts where the business area is subdivided and each message from an unspecified number of people who call you at 1 o'clock when you are away is recorded in order, and is called a business block 4ζ.

An example of a number structure for remote control of the present invention for such a voice storage means is shown below.

■ PIN number: Area △○ area... This is the number to enter remote control. The area shall start playing.

■ Recording: Kenden area...When this number is received, the beginning of the message block currently being played is started and recording is started.

■ Skip playback: 8@mouth area...When this number is accepted, the next message block currently being accessed will be located and playback will begin.

■ Backward playback Engo sphere: When this number is received, the previous message block currently being accessed will be located and playback will be started.

■ Recording deletion: same area...When this number is received, the message recorded in the message block currently being played will be deleted.

As described above, each remote control number has multiple digits, and the first digit of each number is a fixed number (@lI in the above example). Next, an overview of this operation will be shown.

First, the owner of this answering machine sets a password of 1-Δ" and "○" in advance. When you are away from home, record a message in the response area to let you know.

The answering machine automatically closes the loop for calls that come in while the person is away, plays the answering area, and conveys the caller's answering message to the caller.

When the reproduction of the response area is finished, an unrecorded message block among the message blocks is automatically cued and the caller's message is recorded.

In this way, message messages from an unspecified number of callers are recorded one after another in each message block.

On the other hand, when the owner makes a call to this answering machine, the same operation as above is performed, but the owner's purpose is not to listen to the response message that he/she has uttered and to voice the message into the message block, but to indicate that he/she is away. Its purpose is to listen to incoming calls. Therefore, when the response message starts playing, without listening to it to the end,
Dial the PIN number. At this time, first, when the area signal is input, the answering machine receives it and stops playing the response area that was being played up to that point.

When this area signal is input, a response message is being sent, so when the PB double signal sound is superimposed, the sound signal level (
The PR signal can be received by pressing the dial button for a little longer than the normal pressing time (about 100 to 150 m5ec on average) because it contains irregular intervals of large and small amplitude (amplitude) and there are pauses in the sound. device can receive. Note that the PB signal receiver's PB double signal continuous monitoring time is generally about 50 m1IeC.

Once you stop playing the response area, the voice will not be superimposed from then on, so the dial will be the same as when making a normal call.Press the button and enter the preset PIN code of "△" or "○". Finally, input the range signal which signifies the end of the remote control number.

In other words, since no response message is played at this time,
The PB signal receiver is not superimposed with the PB double signal sound, and can operate under normal usage conditions as a PB signal receiver. Moreover, the PB double signal input after the first digit area signal,
Since the signal indicates the specific details of the answering machine operation, malfunction is not allowed, but since the transmission of voice is stopped, there is no possibility of erroneous reception due to the PB double signal frequency component contained in the voice.

As described above, the remote control number is normally received and playback of the business area is started. The owner can listen to each message program, and erase the recording of the unnecessary message block by inputting the recording deletion number area, or delete the recording of the block that is currently being played. If you want to skip the message and listen to other messages, enter the skinzo playback number area (2), and if you want to listen again, enter the return playback number (!) (5) area.Also, change the response message. If you want to do this, just enter the recording number zone when you are in the response area.

In both of these cases, the area signal is first input and the playback operation is stopped, so the significant PB double signal that is input afterwards is received normally, and the audio signal is received incorrectly as the PB double signal. There are no audio malfunctions.

FIG. 4 shows the operation flow of the control section that controls the operation of this answering machine. Note that this figure shows a flowchart from the time when an incoming call is detected, the loop is closed, and playback of the response area is started. That is,
From the time when the reproduction of the response area is started, the PB double signal reception state is entered.

When the PB double signal is received, it is determined whether the signal is a range signal or not. If it is not an area signal, the response message continues to be reproduced, and if it is an area signal, a timer is started and reproduction of the response area is stopped.

That is, even if a PB multiplied signal other than an open signal is received, it is ignored, thereby minimizing the probability of malfunction due to the PB multiplied signal frequency component contained in the response message.

On the other hand, among the various voice band signals, the ones that the PB signal receiver mistakenly receives as an open signal are the cries of infants, folk songs, etc., and even if an open signal is used as a signal to monitor during message playback, it cannot be used as an answering machine. It is considered that there are no malfunctions in actual use.

Next, after receiving the open signal and stopping the reproduction of the response message, the memory is cleared. This memory is for storing the content of the PR open signal received next to the open signal.

After receiving the open signal, the timer starts counting, and if the PB double signal is not received within a certain time, the operation before receiving the open signal is resumed. This happens when the caller accidentally touches the area button.
This is to prevent the caller from being unable to perform any operations when the B signal receiver receives the signal.

If the PB multiplication signal is received before the timer finishes counting, its contents are stored in the memory, the timer count is reset, and the timer starts counting again. Similarly, when the next PR open signal is monitored and the PB double signal is received, its contents are stored in a different address in the memory. Then, after receiving the open signal and receiving the two-digit PB double signal, the last digit of the remote control number, which is the open signal, is monitored, and when it is received, the two PB double signals in the memory are set in advance. It is checked whether or not they match the ``△'' and ``○'' of the personal identification number, and if they match, the playback operation of the business area is started. If they do not match, the reproduction of the response area, which was the operation before receiving the first open signal, is resumed. This is to prevent callers other than the owner from listening to the contents of the message area, to protect Zolaipathy, and to enable remote control to be performed again even if the owner makes a mistake. In this way, after receiving the PB double signal and starting the playback operation of the task area, the PB double signal will continue to be monitored and the remote control numbers for recording, skip play, backward play, and recording deletion can be received. However, since these remote control numbers are 3 digits,
It is sufficient to perform the operation excluding the part 0 shown in FIG.

Next, other embodiments of the present invention will be described.

As mentioned above, the first open signal is superimposed on the voice signal, so even if the caller dials the open signal only once, the voice signal causes the open signal to be distorted, and only one PB signal receiver is required. An open signal may be received as if two or more open signals were input. FIG. 5 shows this state. In other words, if there is a signal with a large amplitude of the reproduced audio within the period when the caller's area button is pressed, the S/N
As the ratio becomes smaller, the PB signal receiver does not receive the open signal during that period, and receives the open signal again during the period when the amplitude of the reproduced audio becomes small.

In order to eliminate this malfunction, in the present invention, the playback operation is stopped when the first open signal is received, but after the caller confirms that the answering machine has stopped the playback operation, the caller presses the button. Even if you stop the PB, there is a time lag.
If the open signal is sent out for longer than the PB signal continuous monitoring time of the signal receiver, the PB signal receiver will assume that the open signal has been sent out twice. As a countermeasure against this erroneous reception, even if an open signal is received again after the first open signal, the second and subsequent open signals may be treated as the first open signal and controlled.

FIG. 6 shows a flowchart of this useless control section. In other words, when the first open signal is received, the timer is started, the playback operation is stopped, and the memory is cleared. The operation is the same as in Figure 4, but the next time the PB double signal is received, the timer is restarted. Start the PB double signal and determine whether it is an open signal. If it is an open signal, move to the next PB double signal monitoring state while stopping the playback operation and do not write anything to the memory. It is. If it is not an open signal, the contents are written in the memory and the process moves to the next PB double signal monitoring as shown in FIG.

In this way, it is possible to prevent malfunctions due to so-called PB multiple signal double counting. In this way, the first digit of each multi-digit remote control number that specifies the operation of the telephone device is all the same number, and even if a PB double signal other than that number is received, the operation of the telephone device is continued. To accurately receive a significant PB signal sent thereafter without erroneously receiving it by stopping the operation that was being performed up to that point when the PB signal 5 set in the first digit is received. I can do it.

In addition, it is possible to recover from a caller's erroneous operation by restarting the previously stopped operation after a certain period of time. , even if you continue to receive the PB double signal,
By regarding this as the first digit signal, it is possible to prevent malfunctions due to pull count of the PB multiplied signal.

In the embodiments of the present invention, an answering machine has been described as an example, but it can also be applied to a voice inquiry notification system that exchanges data using voice guidance, a remote check system that monitors the status of your home while you are away, or various other devices. It can also be applied to remote control systems.

Further, in the present embodiment, the open signal is explained as the first digit number, but other numbers (times to (2), trouble) may be used, and the number of digits is not fixed. Further, although the ending digit of the remote control number is shown as an open signal, this does not apply if the ending digit is not fixed and does not interfere with the operation.

(Effects of the Invention) As described above in detail, according to the present invention, even if the PB double signal, which is a signal in the audio frequency band, is used as a remote control signal, the remote control operation that compensates for the shortcomings of the PB signal receiver can be performed. By doing this, you can perform various operations from anywhere without any malfunctions.
This has the advantage that it can be used without carrying a remote control keypad.
