Abstract

PURPOSE:To exactly correspond to an emergency case by calling a specified intension number through a private exchange (PBX) when a switch is turned on with the operation of a calling person and executing connection to a line wire number designated in advance when the intension number is occupied or in case of absence. CONSTITUTION:At the time of calling, when a calling switch 6 is turned on by an operator, a communication control equipment sends a signal to a PBX 12 and calls the specified intension number. Then, a callable condition with the intension number is obtained. When a calling destination is occupied or in case of the absence, the line is connected with the line wire number designated in advance, Accordingly, only by depressing the calling switch 6, the calling person can execute the call by being connected to the calling destination or another contact destination. Thus, even when the number of the calling destinations goes to be large, it is not necessary to increase a calling button, etc., and even in case of emergency, the speedily correspondence can be executed and operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone used as a communication terminal within a building or between buildings.

[Prior Art] For example, in office buildings, telephones are used as telephone communication devices, and intercoms that are easy to operate are used for making calls within the building. As the number of intercoms increases, the number of locations where intercoms are installed within a building also tends to increase.

[Problems to be Solved by the Invention] However, when making a call using a conventional interphone, the method of calling the other party by operating an individual call button has the problem that if there are many places where the interphone is installed, the number of buttons increases and the operation part becomes large. It is inconvenient to select the destination to call. Also,
While intercoms are easy to operate, they cannot be connected to outside lines, so if the other party is busy or absent, you cannot contact anyone else, which can cause problems in case of an emergency. can be connected to both internal and external lines, but when making a call, it is generally necessary to pick up the handset and dial, which is more cumbersome than using an intercom.

There are also box-speaker type telephones that do not require you to pick up the handset, but in this case, the call status is switched by button operation, so there is a possibility that the call status will be left unattended (forgot to turn it off) even after the call ends. There is. In any case, there is a problem in that they are less convenient than intercoms in terms of operability.

The present invention was made in view of the above-mentioned problems, and its purpose is to eliminate the need for additional buttons, etc. even when the number of call destinations increases both inside and outside the building, and to be able to respond accurately even in emergency situations. It is also an object of the present invention to provide a telephone with improved operability.

[Means for Solving the Problems] The present invention provides a telephone that is connected to a PBX and used as a communication terminal within a building or between buildings, and includes a telephone call switch that is turned on and off by a caller's operation; The present invention is characterized by comprising a communication control device that calls a specific extension number via a PBX when the switch is turned on, and connects to a pre-designated external number when the extension number is busy or absent.

Furthermore, in addition to the above configuration, the telephone of the present invention can be equipped with a sensor that detects the approach of a person.

In that case, if the call switch is turned on while the sensor is outputting a detection signal, the communication control device becomes ready to talk via the PBX, and if the call switch is not operated after the call ends and the sensor outputs the detection signal. The device is configured to release the callable state when a certain period of time has passed since the device has disappeared.

[Function] According to the present invention, when an operator turns on a call switch during a call, one communication control device sends a signal to the PBX to call a specific extension number, and the PBX becomes ready for a call. If the called party is busy or absent, connection is made to a pre-specified outside line.

In addition, when equipped with a sensor that detects the approach of a person, when the person who wants to make a call approaches the phone, the sensor outputs a detection signal, and when the person turns on the call switch,
The telephone becomes ready for calls. After the operator ends the call,
If the user leaves the phone without operating the call switch, the callable state will be canceled after a certain period of time has elapsed since the sensor stopped outputting a detection signal.

Therefore, forgetting to turn it off is prevented.

[Embodiment] FIG. 1 shows a wall-mounted telephone according to an embodiment of the present invention. The wall-mounted telephone 1 shown in FIG. 0 is installed, for example, on a wall inside a tenant of a building. Its appearance consists of a speaker 3, a microphone 4, a sensor 5, a call switch 6, and a plurality of (usually 12) bush buttons 7 arranged on the front of a flat rectangular parallelepiped-shaped casing 2. These components are connected to a central processing unit (CPU) via interface circuits 8 and 9 housed within a casing 2, as shown in FIG.
connected to o. The interface circuit 8 connects the speaker 3. Buikrophone 4. Sensor 5 and call switch 6 and C
The interface circuit 9 is provided between the button 7 and the CPU10.

In addition, inside the casing 2, there is a CPU 1O and a c7) P described later.
An interface circuit 11 interposed between the BX l 2 ports (7) is also housed. In this example, CPUl
0 and interface circuits 8, 9, and 11 constitute a communication control device that controls telephone call operations.

In the above configuration, the speaker 3 and the microphone 4 are means for outputting or inputting audio during a call, respectively. The sensor 5 is a means for detecting the approach of a person, and here detects a person who has come within a certain range from the front of the telephone 1.

As such a sensor, an infrared sensor or other image sensor can be used. The zero call switch 6 is configured as a normally open switch that is turned on by the caller's operation.

The telephone 1 configured as described above is connected to a PBX (private branch exchange) 12 installed in the same building.

The PBX 12 has the function of connecting the telephone 1 with telephones 13 and 14 installed at other locations via an extension line, or with a management device 15 including a telephone installed at a center that manages the building or other locations via an external line. has.

Next, the operation of the embodiment will be explained.

First, as shown in FIG. 3, the telephone 1 of the embodiment performs the following operations when the sensor 5 outputs a detection signal, and the CPU 10 determines whether or not there is a detection signal from the sensor 5.

When the sensor 5 outputs a detection signal as shown in FIG. 4(a), the CPU 10 first checks whether the call switch 6 is turned on, and if it is not turned on, does not execute the following operations. The operation ends.

On the other hand, as shown in FIG. 4(b), the call switch 6
When turned on, CPUl0 calls a predetermined extension number (for example, one or both of telephones 13 and 14 in FIG. 1).
Sends a signal to call the PBX 12. If the other party is absent or busy, CPUl0 processes the call, and if the other party is absent or busy, it automatically dials a pre-specified number (for example, the second specified extension number). The telephone 1 then processes the telephone call, thereby making the telephone 1 ready for telephone calls. Note that whether the other party is absent is determined by whether the number of rings reaches a certain value, and if the other party is busy, it is determined by a specific sound (for example, a green beep).

Therefore, according to this embodiment, one caller can use the call switch 6.
Simply press to connect and talk to the destination or other contacts.

After the above call processing, CPU10 checks whether the call switch 6 has been pressed, and if it is "'les",
As shown in FIG. 4(c), the callable state is canceled and the operation ends. On the other hand, if the call switch 6 is not pressed, the caller moves away from the telephone 411 and the sensor 5 stops outputting the detection signal as shown in FIG. 5(a). At that time, the CPU 10 starts measuring time using a timer,
When a certain period of time T has elapsed as shown in FIG. 5(C),
The call mode is canceled and the operation ends.

Thus, according to this embodiment, even if the caller forgets to operate the call switch 6, the telephone fil can be released from the call state and return to its original state after a certain period of time, and forgetting to turn it off is prevented.

Next, FIG. 6 is a flowchart in which the operation of FIG. 3 is partially modified. In this case, when the call switch 6 is turned on after the sensor 5 outputs a detection signal, similar to the operation at the beginning of FIG. Check if you have done so. If the result is "No", a signal to call a predetermined extension number is sent to the PBX 12 to process the call in the same way as the operation shown in Figure 3, but if the extension number is pressed (specified), (CPL) 10 determines whether the extension is absent or busy. If the other party is absent or busy, the call is processed with the other party at the extension number, and if the other party is absent or busy, the call is automatically sent to a pre-specified location (in this example, the management device fi15 in Figure 1). The person who wants to make a call using the telephone 1 presses the call switch 6 and then inputs the extension number of the person he or she wants to talk to by pressing the pushbutton button, thereby making a call with the desired person. If you can't make a call, you can automatically transfer the call to another contact.

After that, the CPU 10 of the telephone 1 checks whether the call switch 6 has been pressed, and if "Yes", the operation ends, and if "No", a certain period of time has elapsed since the detection signal from the sensor 5 disappeared. When this happens, the callable state is canceled and the operation ends. This is similar to the operating procedure shown in FIG.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto.For example, the form and function of the telephone can be arbitrarily selected as long as the present invention can be carried out.

[Effects of the Invention] According to the telephone of the present invention, when the call switch is turned on, the communication control device sends a signal to the PBX to call a specific extension number. Since the connection is made to the designated external number, the caller can connect and talk to the destination or other contacts by simply pressing the call switch 6. Therefore, even if there are many destinations to call, there is no need to press the call button, etc. There is no need for additional installations, and even if an emergency is required, it can be dealt with quickly, and operability is improved.

In addition, if the phone is equipped with a sensor that detects close proximity, even if the caller ends the call and leaves the phone without operating the call switch, the sensor will no longer output a detection signal for a certain period of time. Since the callable state is canceled once the time has elapsed, it is possible to prevent forgetting to turn it off.
