Abstract

PURPOSE:To inform the occurrence of emergency to the operator of a terminal equipment from other terminal equipment by calling the other terminal equipment in advance without any dialing if an ineffective hook-off of the terminal equipment is detected. CONSTITUTION:When a terminal equipment 101n is hooked off while not being in talking state and reaches a prescribed state (e.g., dialing is not finished within a prescribed time or the like), a call is given to other terminal equipment 105 stored in advance in a storage means 104 corresponding to the terminal equipment 101n. Thus, even if the operator of the terminal equipment 101n cannot make dialing due to a disease, the other terminal equipment 105 is called. Thus, the emergency is informed to a person replied from the other terminal equipment 105 from the terminal equipment 101n.

Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) This invention relates to a telephone device such as a private branch exchange.

(Prior Art) Conventionally, private branch exchanges having a line lockout function are known. This line lockout function generates a warning tone if dialing is not completed within a predetermined time after the phone goes from on-hook to off-hook. This is a function that disconnects the telephone and returns a busy tone to the terminal that made the call to the telephone if the telephone does not go on-hook.

Such functions are executed by a control device such as a microcomputer of the private branch exchange based on a program shown in a flowchart shown in FIG. The operation is explained as follows. When the telephone operator removes the handset and attempts to make a call, the control device detects this (401) and sets its own timer (401).
02). This timer measures when a predetermined period of time has elapsed before generating a warning sound. The control device detects whether input of the dial number is completed (403), and if completed, releases the timer (404) and returns to the main program. If the input of the dialed number is not completed, the timer is referenced to detect whether the time is up (405), and if the time is not up, the process returns to step 403; if the time is up, a timer is set to generate a warning sound for a predetermined period of time, and a warning is issued. A sound signal is sent out (406). This causes a warning tone to be emitted from the handset of a telephone that does not complete dialing within a predetermined time after taking off the handset.

If the operator notices this, it will turn on-hook, so the control device should detect whether it is on-hook (407).
If it is on-hook, it stops sending out the warning sound signal (408), cancels the timer (404), and returns to the main program. Also, if there is no on-hook, the on-hook is detected (407) while referring to the timer and detecting whether the time has expired (409).
, and if the on-footer does not occur even after a predetermined period of time has elapsed since the warning sound was emitted, the transmission of the warning sound signal is stopped (410).
, restore to the main program.

Note that a busy tone is returned to a telephone that makes a call to a telephone whose handset is disconnected, and the telephone is disconnected from step 410 onwards.

Thus, the line lockout function merely generates a warning tone in a telephone that is off-handset. For this reason, there has been a problem in that if an emergency situation occurs for the operator, such as when the operator goes off-hook but falls ill due to illness or the like before dialing, the situation cannot be notified.

(Problem to be Solved by the Invention) As described above, in the conventional telephone device, if the dialing operation is not completed within a predetermined time after the handset of the telephone is disconnected, the telephone generates a warning sound. Therefore, if an emergency situation occurred and the handset was left unplugged, the operator of the telephone could not contact the telephone operator.

The present invention has been made to solve the problems of conventional telephone devices, and its purpose is to prevent a certain terminal from being in a call state, off-hook state, and in a predetermined state (such as dialing not being completed within a predetermined time). ).It is an object of the present invention to provide a telephone device that can notify other terminals of the occurrence of an emergency situation, thereby allowing an operator of the terminal to deal with an emergency situation.

[Configuration of the Invention (Means for Solving the Problems) The present invention provides a plurality of terminals having a transmitting/receiving function, a storage means storing identification information of other terminals corresponding to the terminals, and the terminals. detection means for detecting an invalid off-hook state of the terminal; and when the detection means detects an invalid off-hook state of the terminal, the storage means is searched to retrieve identification information of another terminal corresponding to the terminal, and the identification information is stored in the identification information. The telephone device is equipped with a calling means for making a call to the terminal of the function based on the above information.

(Function) According to the above configuration, when a terminal is in an invalid off-hook state, a call is made to another terminal stored in advance corresponding to this terminal, and the operator of the terminal dials due to illness etc. Even if the terminal becomes inoperable, another terminal will be called, and the person who answered at the other terminal can be notified of the emergency situation from that terminal or by other means.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of an embodiment of the present invention.

In the figure, 1011 to 1011 indicate telephones, which are connected to a detection means 102 constituting a private branch exchange. The detection means 102 has an off-hook dial detection unit 102A and a timer 102B, and detects when dial input is not completed and when the on-hook state is not performed for the telephones 1011 to 101o during a predetermined time after the telephone sets are in the off-hook state in a non-talking state. To detect. For example, as shown in the figure, telephone 4410
1 degree, when the handset is disconnected, the off-hook dial detection unit 102A activates the timer 102B for the telephone 101.
, and a predetermined period of time elapses for completion of dial input. If the dialing is not completed within this predetermined time, the detection means 10 detects that the telephone 1011 is in the predetermined state.
2 to the calling means 103. A memory means 104 is connected to the calling means 103, and the memory means 104 carries out a call when each of the telephones 1011 to 101n (terminals) is in a non-call state, off-hook state, and in a predetermined state. Identification information (numbers) of other terminals to be used are stored. Here, the dial number of the telephone 1ios, which is a terminal, is stored in correspondence with the telephone 101□. Upon receiving the notification from the detection means 102, the calling means 103 searches the storage means 104 for the telephone 101. , and calls the terminal (telephone 105 in this case) based on this identification information. When the telephone 105 answers, an internal circuit of a private branch exchange (not shown) causes the telephone 101. A communication path is established with the operator of the telephone 101o, and the operator of the telephone 101o is able to take appropriate measures such as calling for help even though he/she cannot dial the number, so an emergency situation occurs for the operator of the telephone 101o. You can deal with such situations. A specific configuration of a private branch exchange having each of these means is shown in FIG. The private branch exchange 1 is equipped with a line circuit 7, which is connected to an extension telephone 9 via a signal line 11 and a relay stand 10 via a signal line 12, respectively.

The line circuit 7 is connected via a data highway 8 to a communication path circuit 6 and a central control circuit 5 comprising a microcomputer and the like. A warning signal generating circuit 2, a timer 3, and a memory 4 are connected to the central control circuit 5.

The memory 4 is equivalent to the storage means 104 shown in FIG. Based on its own program, the central control circuit 5 performs various controls to enable mutual calls via the line circuit 7 and the communication path circuit 6 in response to call requests from a plurality of extension telephones 9. In addition, based on the flowchart shown in FIG. 3, it is the terminal that functions as the detection means 102 and the calling means 103 shown in FIG. Relay stand 10
Make a call to

The operation will be specifically explained below with reference to the flowchart shown in FIG. When the operator of telephone 9 removes the handset and attempts to make a call (201), off-hook is detected via line circuit 7 and data highway 8, and timer 3 is set (202). Then, the central control circuit 5 detects via the data highway 8 and the line circuit 7 whether or not the input of the dial number is completed at the extension telephone 9 (203).
), if completed, cancel timer 3 (204)
, restore to the main program. On the other hand, if the input of the dial number is not completed, the timer 3 is referenced to detect whether the time is up (205), and if the time is not up, the process returns to step 203; is newly activated and sends the output signal of the warning signal generation circuit 2 to the extension telephone 9 (206), and controls the extension telephone 9 to generate a warning sound. If the operator of the extension telephone 9 notices this, the handset is returned to its original position and becomes on-hook, so the central control circuit 5 detects whether it is on-hook or not.
07) If on-hook, the output from the warning signal generation circuit 2 is stopped (211), the timer 3 is canceled, and the main program is restored. In addition, if it is not on-hook, it refers to timer 3 and detects whether or not time-up has occurred (208), and detects on-footer (207), and even if a predetermined period of time has elapsed after emitting a warning sound, the device remains on-hook. If not, the information about the called destination is retrieved from the memory 4 (209), and a calling signal is sent to the retrieved called destination via the data highway 8 and the line circuit 7 (210), and the main program is restored. Here, since the relay console 10 is set as the call destination, the relay console 1o is called.

When a call is answered at the relay stand 10, the call path circuit 6, line circuit 7, and data highway 8 are controlled so as to be connected to the extension telephone 9, and after the call path is established, a call can be made.

In this embodiment, a relay stand is shown as the destination, but the destination may be a terminal connected by any external extension line, and for example, it is also possible to call a hospital or fire department. Further, in this embodiment, a telephone that is in a non-calling state, is off-hook, and is in a predetermined state (dial input is not completed within a predetermined time and does not go on-hook even with a warning sound) is connected to a predetermined terminal. However, since sick people cannot respond to calls, a voice signal generator or facsimile device is connected to the central control circuit 5, and the identification information of the telephone in question and the necessary message are transmitted to the called terminal. In this way, it is convenient to be able to determine which telephone terminal an emergency situation is being used with at the called terminal.

In addition, there is no need to send out a warning tone prior to this, and it is sufficient to set this function only for the required telephones.If necessary, it is also possible to register multiple destinations as a countermeasure against busy calls, etc. I'll go.

[Effects of the Invention] As described above, according to the present invention, when an invalid off-hook state of a terminal is detected, another preset terminal is called without dialing.

Therefore, the operator of the terminal can know that an emergency situation has occurred through the other terminal, and can take appropriate action.
