Abstract

PURPOSE:To send an urgent report to a house of an old person, etc., via a general telephone set by transmitting automatically by dialing a message or a special effect sound generated based on the detection and the time of a handset-off state of a telephone set to a prescribed reporting destination. CONSTITUTION:A handset-off state detecting circuit detects a fact that a handset is removed from a telephone set main body, and the telephone set is set in a dial waiting state. At the same time, a timer circuit is started. The timer circuit transmits a signal right before a telephone network decides that the handset-off state is invalid and then instructs a control circuit to take out the reporting destination telephone number stored previously in a telephone number storage circuit. A dial circuit receives the telephone number from the control circuit and automatically dials this telephone number. The telephone network analyzes the dialed number and connects this to a terminating telephone set. When this terminating telephone set answers, this answer is detected by an answer monitoring circuit. Then a sound source circuit sends a message or a special effect sound which are previously registered to the terminating telephone set via a communication circuit. Thus an urgent report can be sent to a house of an old men, etc., by a simplest operation via a general telephone set.

【Example】

(1) FIG. 1 shows a telephone system according to an embodiment of the present invention. In this embodiment, when a single telephone or a cordless telephone connected to a general telephone network is used, a calling telephone reports to a receiving telephone via the telephone network. FIG. 2 is a system diagram when a single telephone is connected to the telephone network. When the handset is detached from the telephone body, the detection circuit detects the handset detachment and enters a state waiting for a dial, and at the same time, activates the timer circuit. Normally, when no dial operation is performed for a certain period of time, the telephone network side determines that the handset is invalid and stops sending dial tone, and stops the transmission of visiton, howler sound, line lockout, etc. However, when the present invention is incorporated and set to operate at any time, the telephone number is taken out from the telephone number storage circuit before the telephone network side determines that the telephone receiver is invalid, and then dials the telephone number. To do. The telephone network analyzes this and connects to the receiving telephone. When the receiving telephone responds, the response monitoring circuit detects it and reproduces a pre-registered sound source through a communication circuit to transmit a voice message or special sound effect to the receiving telephone. (2) Next, FIG. 3 is a block diagram when a cordless telephone is used. When the cordless telephone set is detached from the handset unit (which may be a charger), the control circuit is activated when the handset detachment detection circuit detects it, and the synthesizer circuit selects the frequency for the required channel. The state is shown in the sequence example in FIG. The control circuit transmits a special dedicated transmission signal obtained by adding a data bit indicating that the function according to the present invention is operating to the normal transmission signal to the master unit via the mixer and the antenna. The master unit returns a transmission response signal to the slave unit, indicates a channel to be used, and the master unit and the slave unit perform predetermined channel switching. The master unit connects to the telephone network and at the same time activates the timer circuit and enters a state of waiting for a dial from the slave unit. Normally, when the master unit detects that a certain period of time when the dial operation is not performed is shorter than the time when the telephone network determines that the handset is invalid, the handset determines that the handset is invalid and the handset is indicated by a dotted line in FIG. Therefore, the call cannot be made because the end signal is sent, the wireless channel is disconnected, and the connection with the telephone network is disconnected. However, when the special dedicated transmission signal indicating that the function of the present invention is operating is received, the parent device does not send the end signal shown by the dotted line in FIG. Keep waiting for the dial with the channel connected. If the handset does not operate the operation unit for a certain period of time after detecting the handset removal, the control circuit is activated and the callee telephone number is fetched from the telephone number storage circuit in which the callee is registered in advance. send. The control circuit sends a dial signal to the master unit through the transmitting circuit, the mixer and the antenna. The base unit sends a dial signal to the telephone network side, and the telephone network analyzes this and connects to the receiving telephone. When the called telephone answers, the base unit detects this by the office line interface circuit and sends an incoming response signal to the handset. The cordless handset connects a sound source circuit capable of reproducing a pre-registered sound source to the transmitting circuit and transmits a voice message or a special sound effect to the receiving telephone. (3) FIG. 4 is a diagram showing a key telephone system. The sequence is almost the same as in FIG. In FIG. 2, when the handset of the extension telephone is removed from the extension telephone main body, the extension telephone is connected to the main unit of the button telephone. Inside the extension telephone, the handset disconnection detection circuit detects the handset disconnection and the control circuit is activated to send a special transmission signal in addition to the normal transmission signal and the data bit indicating that the function according to the present invention is operating. . The main unit returns a call origination response signal to the extension telephone, and at the same time activates a timer circuit to enter a state of waiting for a dial signal from the extension telephone. Normally, the main unit does not perform dial operation after a certain time elapses. Since it is determined that the receiver is invalid, the process such as sending out the busy tone shown in FIG. 6 is performed and the call cannot be transmitted. However, the main unit continues to wait for the dial signal even if the timer circuit times out because it receives the special dedicated transmission signal indicating that the function of the present invention is operating. Even if the extension telephone does not operate the operation unit for a certain period of time after detecting the handset disconnection, the control circuit is activated and the callee telephone number is fetched from the telephone number storage circuit in which the callee is registered in advance, and the control circuit Send to. The control circuit sends a dial signal to the main device via the dial circuit. When the dial signal is an ordinary telephone network, the main unit sends the dial signal to the telephone network side, and when the dial signal is an extension telephone, it connects to the corresponding extension telephone. The telephone network analyzes this and connects to the receiving telephone. When the receiving telephone or the extension telephone responds, the response monitoring circuit detects this and sends an incoming response signal to the extension telephone. The extension telephone is connected to a sound source circuit that can play back a pre-registered sound source. Tell. (4) Next, a case of a cordless telephone in the embodiment of FIG. 4 will be described. The sequence is almost the same as in Fig. 6 The handset of the cordless telephone handset is the handset body (sometimes a charger)
When the handset disconnection detection circuit detects the handset disconnection, the control circuit is activated and the synthesizer circuit selects the frequency for the required channel, and the normal oscillation signal to the mixer and antenna indicates that the function according to the present invention is operating. A special dedicated call with data bits added is sent to the base unit. The master unit returns an outgoing response signal to the slave unit and indicates the channel to be used. The parent device and the child device switch to a predetermined channel. The master unit is connected to the telephone network and at the same time activates the timer circuit to enter a state of waiting for a dial from the slave unit. Normally, the master unit determines that the handset is invalid when the dial is not operated for a certain period of time, disconnects the wireless channel by sending the end signal shown by the dotted line in FIG. 6, and connects to the telephone network. You cannot make a call because the call is disconnected. However, when the special dedicated calling signal indicating that the function of the present invention is operating is received, the master unit does not send the end signal and continues to wait for the dial while the wireless channel is connected. Even in the slave unit, if the operation unit does not operate for a certain period of time after detecting the removal of the handset, the control circuit is activated, the notification destination is registered in advance, and the notification destination telephone number is retrieved from the telephone number storage circuit and sent to the control circuit. . The control circuit sends a dial signal to the master unit through the transmitting circuit, mixer and antenna. When the dial signal is a general telephone network, the master unit connects the corresponding slave unit to the telephone network side when the dial signal is a slave unit. The telephone network analyzes this and connects to the receiving telephone. When the incoming telephone or the incoming slave responds, it is detected by the station line interface circuit and sent to the slave. The slave unit connects a sound source circuit capable of reproducing a pre-registered sound source to the transmission circuit and transmits a voice message or a special effect sound to the receiving telephone. (5) Next, when using the extension telephone of the private branch exchange shown in FIG. 5, when making a call from the extension telephone and notifying an incoming telephone of the ordinary telephone network via the ordinary telephone network, or making a call from the extension telephone. The configuration of the telephone is substantially the same as that of FIG. 2 in the case of making a call to another extension telephone and the description thereof will be omitted. (6) FIG. 7 shows another embodiment of the present invention. If an emergency occurs and you try to call a contact by using a normal phone call method, but the operation cannot be connected during dialing on the phone, the telephone network side determines that the operation was interrupted during dialing and the busy tone It is not possible to contact the addressee because of the measures such as sending. In Fig. 7, when the handset of the telephone body directly connected to the general telephone network is removed, the handset disconnection detection circuit detects the handset disconnection and waits for dialing. In this state, the switch circuit is open and connected to the telephone network. It has not been. When it is detected that the handset is taken off, the timer circuit is activated to wait for the dial operation, but a state where no dial operation is performed elapses for a certain time.
When a certain period of time passes between digits, it is determined that an emergency situation has occurred, the switch circuit is closed and the telephone line is connected, the control circuit is activated and the telephone number of the telephone number is registered in advance. Take out and send to the dial circuit. The dial circuit sends a dial signal suitable for the circuit type to the telephone network side. The telephone network analyzes this and connects to the receiving telephone. When a call is received from the receiving telephone, the response monitoring circuit detects it and reproduces a pre-registered sound source, and transmits a voice message or special sound effect to the receiving telephone through the communication circuit. (7) Next, when the receiver is placed in a place where the handset cannot reach, such as a bedridden elderly person, etc. An example in which the present invention cannot be effectively used is shown in FIG. Make it possible to easily extend the string and remove the handset. Next, a specific example of the method for detecting the handset disconnection will be described. One example of the method for detecting the handset disconnection detects that a current flows directly to the telephone when the handset is detached from the telephone body. Another way to detect handset disconnection is to monitor the closure of hook switch contacts that have contacts other than the contacts that control the telephone circuit. Another method for detecting the removal of the handset is that in a cordless telephone, if the handset or handset is placed on the base unit or charger, the charging current of the battery is flowing but the handset (or handset) is the base unit. It detects that the charging current of the battery stops flowing when it is removed from (or the charger). (8) Next, an example of setting the timer is shown. In the case of a general telephone network, when the telephone handset is unhooked, it sends a dial tone and enters the waiting state for dialing, but if dialing is not performed for about 20 seconds, it is judged that the handset is invalid and the dial tone is stopped and the busy tone is sent. Take necessary measures such as howler transmission, line lockout, etc. Therefore, the timer should be set to about 15 seconds. The same applies when using a private branch exchange or an extension telephone of a key telephone device. Although the initial value of the timer is set to the above, it is preferable that the timer is not fixed but can be changed depending on the installation location. (9) Next, an operation example when the other party does not respond will be shown. You can register multiple pre-stored phone numbers to be contacted in descending order of priority and call the first phone number for a certain period of time. In this way, when all the report destinations are sequentially called and there is no response, the process returns to the beginning and repeats. If there is no response, take a certain pause time and repeat again. The ordering is arbitrary, but generally, the priority of the callees who have a high degree of urgency is sequentially called to high priority.

As described above, when the telephone system according to the present invention is installed in a single-family home such as an old man's home or an old man's room, it becomes possible to report accurately and promptly in the event of sudden physical change, accident or incident. It is a telephone system having a characteristic that it can be used as a normal telephone.
