Abstract

PURPOSE:To recover the state into the state just before power failure with very high reliability at the point of time of power failure restoration by storing novel control information in a dial memory of a dial IC subjected to battery backup in the low power consumption mode during power failure. CONSTITUTION:When control information is generated novelly, a control means brings the dial IC into the control mode and stores the control information in the dial memory of the dial IC. The control information stored in the dial memory is read properly based on the control signal from an external device such as s main CPU. A standby circuit 20 detects a voltage of a station power supply or AC 100V commercial source and the dial IC 16 is in the backup state by a battery 19 at a prescribed voltage or lower and brought into the low power consumption mode. Thus, the content of the dial memory is preserved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention stores control information such as the presence or absence of function settings, setting conditions, constants, etc. generated by external setting operations and function execution operations, and performs control operations based on this control information. This invention relates to a functional telephone device that controls its functional operations.

[Conventional technology]

In a conventional functional telephone device of this kind, generated control information is stored in a dedicated memory, and the contents of the memory are read out as necessary to execute a desired operation. On the other hand, in high-end models that require high reliability, it is necessary to take measures against power outages for such memories. That is, it is necessary to provide a battery and a peripheral circuit to prevent memory contents from disappearing due to a power outage.

[Problem that the invention seeks to solve]

However, adding a dedicated battery and peripheral circuitry increases the cost, and furthermore, the reliability is not sufficient considering that the battery runs out.

[Means for Solving the Problems] The functional telephone device of the present invention has been made in view of the above problems, and the dial IC with dial memory retains speed dial and auto dial information for a long period of time. Because of the need to do so, we focused on the fact that battery backup is provided in low consumption mode during power outages or on-hook. That is, there are two modes: a normal mode in which various dial calls and dial registrations are made according to key operations, and a control mode in which various dial calls and dial registrations are made by external control signals, and the registered dial information is read out. a dial IC with a dial memory and which is backed up by a battery in the event of a power outage; and a control means for controlling the dial IC to a control mode when the control information is newly generated and storing the control information in a predetermined area of the dial memory. It is equipped with the following.

[Effect]

When new control information is generated, the control means is dial IC.
into control mode and dial its control information.
Store it in C's dial memory.

Then, the control information stored in the dial memory is read out as appropriate based on a control signal from an external device such as the main CPU. Additionally, if there is a power outage, the contents of the dial memory are retained by the backup power supply.

〔Example〕

Hereinafter, the present invention will be described in detail along with examples.

FIG. 1 is a block diagram showing an embodiment of the present invention applied to a tape deck type answering machine, and FIG. 2 is a partially detailed block diagram showing a part of the same in detail.

The telephone line is hook switch HS2 and call circuit 3.
It is connected to the handset 4 via. The input terminal of the ringer generating circuit 5 and the fixed contact side of the relay switch 6 are connected between the telephone line and the hook switch H32. The ringer generation circuit 5 generates a ringer sound based on the incoming signal from the telephone line, and when it detects the incoming signal, provides the detection output to the main CPU 7.

The relay switch 6 is a switch whose opening/closing is controlled by a relay 61 , and the movable contact side is connected to a first terminal of a hybrid circuit 9 via a transformer 8 . The second terminal of the hybrid circuit 9 is connected to the input terminal of the amplifier circuit 10, and the output terminal of the amplifier circuit 10 is connected to the input terminal of the incoming message (ICM) tape deck lla of the tape deck mechanism section 11. There is. On the other hand, the third terminal of the hybrid circuit 9 is connected to the output terminal of the amplifier circuit 12, and the input terminal of the amplifier circuit 12 is connected to the output terminal of the outgoing message (OGM) tape deck 11b of the tape deck mechanism section 11. It is connected. In the hybrid solid circuit 9, the signal from the amplifier circuit 12 is output only to the transformer 8 side, and the signal from the transformer 8 side is output only to the amplifier circuit 10 side.

The tape deck mechanism section 11 is driven and controlled by the deck control circuit 13 based on commands from the main CPU 7, and as mentioned above, the tape deck mechanism section 11 is configured to be driven and controlled by a deck control circuit 13 based on instructions from the main CPU 7.
It is a two-deck system with separate tape decks for M. OGM tape deck b records a so-called response message as OGM, and is activated immediately after receiving a call to send the response message, ie, a message to the effect that the caller is absent, to the caller. The ICM tape deck lla is used to record a caller's message (ICM).

An output terminal of a transmitting circuit 14 and an input terminal of a constant current circuit 15 are connected to a connection point between the hook switch HS2 and the telephone call circuit 3. The transmitting circuit 14 is a means for transmitting a selectively inputted dial pulse signal or a composite audio frequency signal from the dial IC 16 to the telephone diagram vAL, and the constant current circuit 15 is a means for transmitting an AC on the telephone line at the time of off-footer. This circuit cuts the component and supplies the local current to the dial IC 16 as a power source.

The dial IC 16 has an internal configuration as shown in FIG. 2, and includes a dial memory 31, a control circuit 32, an A/D
It is composed of a converter 33, a pulse output circuit 34, and a tone output circuit 35. The pulse output circuit 34 outputs a dial pulse signal, and the tone output circuit 35 outputs a composite audio frequency signal based on the output of the control circuit 32. It is designed to be output selectively. Such dial I
The C16 has two modes, a normal mode and a control mode, and in the normal mode, various dial calls and registrations can be made in accordance with key operation information from the key manual means 17. In addition, in the case of the control mode, key operation information from the key manual means 17 is sent to the main CPU, and
Control signals from the main CPU 7 allow various dial calls to be made and registered, as well as registered dial information to be read out. In this embodiment, the control mode of the dial ICL 6 is used to control specific areas of the dial memory 31.
Control information such as state setting conditions and constants necessary for operation of the answering machine is written and read, and the latest control information is always held in the specific area.

In addition to the local power supply from the constant current circuit 15, the power supply for the dial IC 16 includes a 5" made from the AC 100V power supplied to the terminals on the 1st day. At the time of on-footer, the former
The latter is used for off-footer operations. In addition, a battery 19 is used as a backup power source in the event of a power outage when off-hook.
is provided. The standby circuit 20 detects the voltage of the local power supply or the ACIoov power supply, and when it detects that these power supply voltages have fallen below a predetermined voltage, it provides a detection signal to the hold terminal of the dial IC 16. Based on this detection signal, the dial IC 16 detects that it has entered the backup state by the buffer battery 19, and shifts to a low consumption mode, that is, a dial information storage retention state with low power consumption.

The lighting of the lamp group 21 is controlled by the main CPU 7, and includes a "busy lamp", an "absence lamp", and the like. Further, the key input means 22 is provided separately from the key input means 17, and its key operation information is provided to the main CPU 7. Further, the main CPU 7 has a built-in timer means.

Next, the operation of this embodiment will be explained using the flowchart shown in FIG.

When the power is turned on, it is initialized (step 1).
01), dial memory 31 for dial IC 16
A read command for address n is executed (step 102). In this embodiment, various control information necessary for operating the answering machine is held at address n, and the control information read out based on this read command is stored in the main CPU (step 103, 104). In this embodiment, for the sake of simplicity, the control information is assumed to be an "absence flag," a "business flag," and a "recording counter (N)." When the storage of the control information is completed (step 105), the state of the task flag, which is one of the stored control information, is determined (step 106). The task flag is on the ICM tape deck lla.
This flag is “on” when the message message (IC, M) is stored in the message message (IC, M), and when the message flag is “on”, the lamp with message in the lamp group 21 If it is "off", the task lamp is turned off (steps 107 and 108).

Next, it is determined whether the absence flag in the control information is "on" (step 109). The answering flag indicates whether or not the answering machine of this embodiment is set to the answering mode. When the answering machine is in the answering mode, the answering flag is "on", and when it is not in the answering mode, that is, in the home mode, the answering flag is "on". The out-of-office flag is "off." If the absentee flag is "on" in the judgment 109, the absentee lamp in the lamp group 21 is turned on, and if it is "off", the absentee lamp is turned off (step 110.133).

Here, it is assumed that the absentee flag is "on", and after turning on the absentee lamp (step 110), key operation inputs and incoming calls are monitored (steps 111 and 112). The case where there is a key operation input will be described later, and here it is assumed that there is an incoming call (step 112). When there is an incoming call, after connecting the line (step 113), OGM
The OGM is sent to the telephone line by driving the tape deck llb (step 114). A 00M end mark is attached to the end of the OGM during recording, and the transmission is stopped when this mark is detected (step 115,
116).

Subsequently, the value M of the counter included in the main CPU 7 is set to zero (step 117), and the ICM tape deck lla is driven to start recording the message from the caller. (Step 11 &) Immediately after the start of recording, start the timer means built in the main CPU 7 (Step 119), and detect the pulse input from the tape deck mechanism 11 until the timer means times out. The value M of the reel counter is increased by "1" each time (step 120.1
21.122).

The pulses output from the tape deck mechanism section 11 are
It is output in accordance with the rotation of the reel of the M tape deck lla, and for example, three pulses are output for one rotation of the reel. Therefore, the value M of the reel counter indicates the amount of rotation of the reel of the ICM tape deck lla. Recording normally ends when the caller goes on-hook, but it is also forced to end if the recording time exceeds a predetermined time.

For simplicity, this example shows a case where recording is stopped for the latter reason, that is, because the recording time exceeds a predetermined time. After recording is stopped due to time-up (step 123), a beep tone is sent (step 124), the busy flag is turned on (step 125), and the busy lamp is turned on (step 1).
26) Release the line (step 127).

After the line is released, in step 103, the value N of the read recording counter is changed to the value M of the reel counter at the end of the current recording.
are added, and the result is set as a new recording counter value N (step 128). Next, n of the dial memory 31
A write command is issued to the address (step 129),
The latest information on the business flag and the absentee flag is written into the dial memory 31 along with the new recording counter value N (step 130). This means that the control information has been rewritten. After that, OGM tape deck l
lb is driven to rewind the OGM (step 131
), and when the rewinding is completed, the process returns to step 106 (step 132).

The above explanation is based on a case where the absentee flag is "on J" in judgment 109 and an incoming call is received without any key operation in steps 111 and 112, but when the absentee flag is "off" here. In this case, the user turns off the absentee lamp and waits while monitoring key operation input (step 134).

If there is any key operation during the monitoring standby state in steps 111 and 112, and if there is any key operation in step 134, the key operation selects either the at-home mode or the away mode. It is determined whether or not this is a key operation (step 135). If it is neither, execute the corresponding key operation and step 10.
6 (step 136). If the mode is either the away mode or the home mode, it is then determined whether the away mode has been selected (step 137), and if it is the away mode, the away flag is turned on (step 12).
9, the control information in the dial memory 31 is rewritten as described above. However, at this time, the actual content of the control information may not change.

If the key operation in steps 111 and 134 is an operation of the at-home key, the process moves from judgment 137 to step 139 and rewinds the ICM (step 140);
When rewinding is completed, reproduction of the ICM is started (step 141). The value M of the reel counter is set to zero at the start of ICM playback (step 142), and the value M of the reel counter is set to zero when the ICM starts playing.
The pulses output from the CM tape deck lla are detected and added (steps 143, 144), and when the value of M matches the value of the recording counter N (step 145), I
The reproduction of the commercial is stopped (step 146). Thereafter, the task presence flag is set to "off" and the process moves to step 129, where the control information in the dial memory 31 is rewritten.

In this way, during the basic operation of the answering machine,
The control information is read from the dial memory 31 or written to the dial memory 31 as appropriate, and the latest control information is always held in the dial memory 31.

Although this embodiment applies the present invention to an answering machine, the present invention is not limited thereto, and any other telephone device may be used as long as it has a dial IC and performs predetermined operations based on control information. It can also be applied to other telephone devices.

Moreover, the control information of this embodiment shows an example, and is not limited to this. For example, if a message IC memory is used instead of a mechanical tape deck, the control information may include address data of the IC memory,
Possible factors include recording time and whether or not each area is recorded.

〔Effect of the invention〕

As explained above, according to the functional telephone device of the present invention, when new control information is generated, the new control information is stored each time in the dial memory of the dial IC, which is powered up in a low consumption mode during a power outage. Therefore, even if there is a power outage, the control information is retained and does not evaporate. Therefore, when the power outage is lifted, the state immediately before the power outage can be restored with very high reliability. Moreover, since the dial IC for dialing and registering is also used as a memory for control information, it can be provided at low cost.
