Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone (hereinafter referred to as a telephone) used in a button telephone device.

[Conventional technology]

Telephones for pushbutton telephones have various functions in addition to functions for making and receiving calls and talking using a handset, but recently they have come to be equipped with a self-check function, as described in Japanese Patent Application Laid-Open No. 58-186251 and Japanese Patent Application No. 58-97723 have been proposed.

In other words, in the former case, a switch is provided for setting the handset number, and if the switch is switched to the test number and then the power is turned on, self-check is possible, and after the self-check is completed, the switch is returned to the number setting position. In the latter case, self-checking is possible by performing a series of key operations during on-hook, and returning to a steady state when off-hook. .

[Problem that the invention seeks to solve]

However, in the former case, after the self-check is completed, the power must be turned off and then on again, and the handset number must be reset, which is cumbersome to operate and requires resetting the handset number. creating a risk of error.

In addition, in the latter case, if a key is operated accidentally or carelessly while in the on-hook state, there is a risk that the device will enter a state in which self-check is possible, making it impossible to make or receive calls, and the keys required to enter the self-check state may become inoperable. A clock pulse from the main device is required for detecting operation and flashing the lamp during self-check, making it inconvenient that self-check cannot be performed by the telephone alone.

The present invention has the purpose of fundamentally solving the problems of the conventional technology, and provides an extremely effective key telephone.

[Means for solving problems]

In order to achieve this object, the present invention is constituted by the following means.

That is, a dial key for dialing,
A button telephone having a plurality of function keys and a visual display means and an audible display means operated based on control from a main device, a detecting means for detecting the state of a touch switch, and an initial state of the detecting means after power is turned on. a timer that starts in response to the off-hook detection output of the timer; a mode setting means for setting a test mode in which a self-check is performed when one of the keys is operated while the timer is operating; drive means for sequentially driving the visual display means and the audible display means with information corresponding to the operation keys when the test mode is activated; and a reset means for terminating the test mode in response to an on-hook detection output of the detection means during the test mode. It is something.

[Effect]

Therefore, if any key is operated while the timer is operating after the power is turned on and off-hook, the test mode will be entered, and the predetermined test will be performed according to the information corresponding to the operation key according to the key operation. Displays, pronunciations, etc. are performed, and self-checks are performed.
Then, the test mode is reset on-hook.

〔Example〕

Hereinafter, details of the present invention will be explained with reference to figures showing examples.

FIG. 1 is a block diagram, in which line terminals 1a and 1 are connected to a communication line 1 from the main device, which is omitted in the figure.
Line transformers 3a and 3b are inserted into the line terminals 2a and 2b connected to the similar signal line 2 and the line terminals 2a and 2b, respectively, and the power supplied from the main device via the communication line 1 and the signal line 2 line transformers 3a, 3b
Extracted from each primary side neutral point of
A handset 6 is connected to the secondary side of the line transformer 3a via a communication circuit 5, and a speaker 8 is connected via an amplifier circuit 7 to the secondary side of the line transformer 3a. is connected.

Further, the output of an oscillator 9 that generates various tone signals is given to the telephone communication circuit 5 and the amplifier circuit 7, and the output of the oscillator 9 that generates various tone signals drives the speaker 8 as an audible display means or the receiver of the handset 6. It has become something that is done.

On the other hand, a control circuit 10 consisting of a processor such as a microprocessor, a memory, etc. is provided.
As a result, the state of the switch HS is detected, and the operation status of the dial key 11 for dialing and the keyboard 12 having a plurality of function keys is detected, and the detection results are used as operation data for the transmission circuit 13 and the line transformer. 3b, the data is encoded and transmitted to the main device.

In addition, in the main device, the exchange operation is performed according to the received operation data, and the control data is encoded and transmitted, so this is sent to the control circuit 1 via the line transformer 3b and the transmission circuit 13.
0 receives and according to the control data the oscillator 9,
Controls the telephone call circuit 5, the amplifier circuit 7, and the display unit 14 equipped with a plurality of indicator lights used as visual display means, specifies a tone signal to be sent to the oscillator 9, and instructs the call circuit 5 to accept the tone signal;
It gives operation commands to the amplifier circuit 7, etc., and drives each indicator light to the display section 14.

However, the above is a steady state, and if the power to the main device is turned off and then turned on again, or if the line terminal 1
When the power is turned on by removing and reattaching the connectors, etc. to a, 1b, 2a, and 2b, and then the off-hook is performed, the control circuit 10 shifts to the test mode, and only for a certain period of time, for example, 5 seconds. You can start self-checks freely.

FIG. 2 is a flowchart of the control situation by the processor in the control circuit 10, and is
The processor enters the operating state, detects the state of the hook switch HS, and if the detected power is Y (YES) of "Off hook?" 101, a "timer start" configured in the processor is executed accordingly. 102, and by detecting the operation status of the dial key 11 and the keyboard 12, when any key becomes "Y" for "key operation?" 111, "timer reset" 112 is performed,
The "operation check" 121 controls the oscillator 9, the communication circuit 5, the amplifier circuit 7, and the display section 14 that correspond to the operated key, and drives the receiver of the handset 6 or the speaker 8 with a tone signal, or The indicator light in the display section 14 is turned on, and the "ON HUCK?" 122 is set to N.
While (NO), steps 121 and above are repeated, and the process returns to "normal processing" according to Y in step 122.

Furthermore, when step 111 is N, "timer reset" 132 is performed in response to "on hook?" 131 becoming Y;
If so, “Timer/time up?” 133 is Y
Then, the process returns to "normal processing".

Note that when step 101 is N, the process immediately shifts to "steady processing" and therefore does not become a test mode.

FIG. 3 is a flowchart showing the operation and display status when the test mode is entered. In response to the transition to the test mode, "all indicator lights/lights" 201 are performed, and when "keyboard operation" 202 is performed, After “corresponding indicator light/off” 203 is completed and “all indicator lights/off?” 204 becomes Y, when “dial key operation” 211 is performed, “key=?” 212 is activated. The tone signal transmission status is classified according to the key, and when the key is “1or4or7or〓”, “tone 1 is sent from the speaker” 221, and when the key is “2or5or8or0”, “tone 2 is sent from the speaker”.
When the key is "3or6or9or#", the tone 3 is heard from the receiver of the handset 6.
Check all these operations and displays, and then select “Check completed? When ``231'' becomes Y, ``on-hook'' 232 is performed and the self-check is completed.

However, if only power is supplied to the line terminals 1a, 1b, 2a, 2b from a separate power supply device etc., step 201 will be lit continuously;
When properly connected to the main device, polling signals or control data etc. arrive periodically via signal line 2, so the lighting status will repeatedly blink in response to the reception of this, and the connection between the main device and You can check the connection status and reception function of control data, etc.

Also, "tones 1 to 3" of steps 221 to 223
For example, since "Tone 1" is defined as a central office line ringtone, "Tone 2" is defined as an extension ringtone, and "Tone 3" is a ringtone from a doorbell, the generation status of each tone signal and the status of the audible display means are determined. Since the dial key 11 can be confirmed and the tone continues to be sent while the corresponding key is being operated, it is possible to confirm whether or not there is an abnormality in each dial key 11.

Therefore, the self-check is performed by a simple operation, there is no risk of setting the handset number incorrectly, and if a separate power supply is provided, the phone can perform the self-check by itself, and can be used to demonstrate the phone functions. It is suitable for calls, etc., and if a self-check is not performed, it will automatically return to a steady state after a certain period of time, so there is no risk that it will be impossible to make or receive calls.

In addition, as shown in Figure 3, the switch HS,
Checks the on/off status according to the operation of the dial key 11 and keyboard 12, as well as whether each circuit of the oscillator 9 to handset 6 and speaker 8 is normal, and whether each indicator light on the display section 14 is disconnected or shorted. Since all operations and display functions of the telephone can be locally confirmed, such as whether or not the telephone is installed or not, it is extremely convenient for checking when installing or expanding a telephone, and for maintenance and inspection.

However, in FIG. 1, the control circuit 10 may be configured by a combination of various logic circuits, and the same effect can be achieved even if the power is supplied only from the signal line 2 or from a commercial power source, etc. The oscillator 9 may be capable of generating a larger number of tone signals, or the tone signal may be transmitted only from the speaker 8 or the receiver of the handset 6, and the display section 14 may include a light emitting diode, a lamp, or Various display elements may be used.

In addition, in FIGS. 2 and 3, the present invention can be modified in various ways, such as replacing the steps, omitting unnecessary steps, or replacing them with other equivalent steps depending on the conditions. is free.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, local self-checks can be performed as a standalone telephone by simple and error-free operations, and therefore remarkable effects can be obtained as a telephone for various button telephone devices.
