JPH03229551A - Transfer telephone remote controller - Google Patents

Abstract

PURPOSE:To eliminate the need for retrying an operation from the beginning like a conventional manner by allowing a micro computer to judge whether a system follows a previously decided operation procedure or not and ignoring an interruption call even when it occurs from a third person in the middle of the operation procedure. CONSTITUTION:When a telephone set provided with this transfer telephone remote controller is called, a detection part 1 detects the bell signal. When N-times ring back tones previously decided are received, the call is tentatively hung up and the call is made again within prescribed time, S seconds. When it is within prescribed time, a line relay circuit 13 is activated by the instruction of a program memory 7. Telephone circuits L1 and L2 and a transmission/ reception separation circuit 2 are connected and the line is closed. In a case when the system differs from the previously decided operation procedure, the operation by a person excepting the person himself is executed, for example, the micro computer does not receive it and the system goes to a waiting state until accurate input is executed. Even if there is the interruption call from the third person between first and second calls, the operation is prevented from being interrupted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Use] The present invention relates to a telephone transfer device, and more particularly to a remote telephone transfer control device that can remotely start, stop, change, etc. the transfer.

[Conventional technology] Conventionally, any telephone number was registered in advance as a forwarding destination (
There is known a telephone transfer device that automatically transfers an incoming call to the telephone set accordingly.

This forwarding phone allows incoming calls to be transferred to any forwarding destination and answered even when the person in question is not at the location where the phone is installed or the company is closed or closed. We are expanding the scope of activities of people involved in various types of work that are considered essential means. Furthermore, since the transfer destination is not limited to one location, the transfer destination can be changed arbitrarily as necessary.

For this reason, the use of new management systems is spreading, such as streamlining telephone reception by centralizing it, and eliminating the need for overtime or night shifts in industries that require 24-hour reception, such as service and maintenance industries. There is.

Conventionally, there are two methods for transferring calls: a method using an exchange, and a method using a terminal.

As shown in Fig. 2, in the method using a switchboard, the telephone number of the forwarding destination telephone C is registered in advance in the switchboard S in the central office using the receiving telephone set, and then the telephone number is used to carry out the specified transfer operation. If you do this, when there is a call from telephone A on the calling side to telephone I, the call will be forwarded to the forwarding destination telephone C via the exchange S, and the telephone C will be able to listen to the contents of the call from telephone Ila. be.

Further, if an operation is performed to stop the forwarding using the receiving side telephone, the forwarding is stopped and the call from telephone A can be received by the telephone.

As shown in Figure 3, the transfer method using a terminal requires two telephone lines on the receiving side: a receiving telephone e and a calling telephone f.
A transfer device T is provided to control both telephones e and f, and the telephone number of the transfer destination telephone lag is registered in advance by the telephone f.

When a call is placed from the calling phone d to the receiving phone e, the transfer device T detects the ringing of the phone e, and immediately calls the registered transfer destination phone g from the phone f, and then picks up the receiver of the phone g. When you raise it, you will hear a notification sound from the sender, informing you that it will be transferred, and the transfer device T.
responds to telephone e, connects telephones e to f to each other, and allows telephone g to hear the call from telephone ID to telephone e.

[Problems to be Solved by the Invention] However, when performing operations such as registering or changing a forwarding destination telephone number, or starting or stopping forwarding, the forwarding (
In Fig. 3), not only can the telephone f be operated directly, but also the telephone e can be operated using any telephone such as a public telephone.
It is known that this can be done in a remote location away from telephone f using two lines -f, but the transfer method using the exchange (Figure 2) had the drawback that it could only be operated by the incoming telephone. .

Therefore, when you are away from the phone, such as when you go out,
Even when you want to start or stop a transfer or change to another destination, you always have to return to the location where the telephone is installed, which is very inconvenient.

Therefore, the present applicant has previously proposed a transfer control remote device that can start, stop, change, etc. the transfer from a remote location even in the transfer system using an exchange (Japanese Patent Application No. 63-312
No. 889).

In this invention, a relay contact is provided to switch between a call circuit and a transfer data sending circuit, and the circuit is switched when a second call is received within a predetermined time after the first call. If there was an interrupt call from a third party between the first call and the second call, the operation would have to be repeated from the first call.

In view of the above, the present invention is equipped with a microcomputer that determines whether or not the operation is correct, so that even if there is an interrupt call from a third party, if the operation is not correct, the call will be ignored, and the next call from the person in question will be ignored. It is an object of the present invention to provide a transfer control remote device capable of accepting a second call.

[Means for Solving the Problems] In order to achieve the above object, the remote telephone transfer sterilization device of the present invention includes a communication circuit and a transfer data sending circuit for sending transfer data such as registration and change of transfer destination. A telephone equipped with a telephone, a detector that detects the first ring signal from another telephone in a remote location, a counter that is activated by the signal from the detector, and a detector that detects the second ring within a predetermined time. It is equipped with a microcomputer that determines whether a signal is detected, and a transmission/reception separation circuit that operates a line relay circuit based on the signal from the microcomputer and switches from the communication circuit to the transfer data transmission circuit.

[Function] With the above configuration, the transfer remote control device of the present invention can transmit any telephone,
For example, if you call the phone once from a public phone, then -
hang up and then call again within the specified time.

At this time, the microcomputer determines whether or not a predetermined operating procedure is followed, and if the procedure is correct, the operation is executed as is to start, stop, change the transfer destination, etc.

In addition, if the operation procedure is different from the predetermined one, such as when operated by someone other than the user, the microcomputer will not accept it.
After that, it will be in a standby state until the correct input is made.

Therefore, even if an interrupt call from a third party occurs between the first and second calls, the operation will not be interrupted.

In addition, since it is equipped with a microcomputer, there is a control timer function that automatically sends data at a specified time, a shortcut operation function that allows you to register multiple forwarding destinations in advance and change them with one touch, and a quick operation function that allows the operator to know which operation procedure to perform next. It is easy to use and allows various functions such as a voice response function to notify users.

Next, the operating procedure will be explained.

When a call is made to a telephone equipped with the forwarding telephone remote control device of the present invention using another button telephone installed at a place other than the telephone installed, the detecting section 1 detects the ring signal, and the
The information is transmitted to the CPU unit 5 via the PU interface circuit 4, and the bell counter in the CPU interface circuit 4 is activated for a predetermined period of time.

When the ringtone rings a predetermined number of N times, the call is hung up and the call is made again within a predetermined time of S seconds. At this time, similarly to the above, the detection section 1 detects the bell signal and transmits it to the microcomputer 5 via the CPU interface circuit 4, and causes the bell counter to determine whether or not the predetermined time is within S seconds.

If it is within the predetermined time, the line relay circuit 13 is activated via the CPU interface circuit 4 according to the instruction from the program memory 7, and the relay contacts S1 and S2 are switched to connect the telephone line L1 and Lx to the transmitting/receiving separation circuit 2. and close the line.

Further, the CPU unit 5 activates the voice response circuit 15 via the CPU interface circuit 4, and notifies the operator of the operation contents by voice, such as ``Please give the r command 1''.

On the other hand, a command to start changing the transfer destination, a transfer start command, a transfer stop command, a timer set command, an option command, etc. are determined in advance as #1 to #5, respectively, and these are sent to the command setting circuit 17 using the set switch 18. Once stored, each command can be sent simply by sending PB tone #n (number).

At this time, as before, the voice response circuit 15 announces ``Please enter the transfer destination number 1''.

As a result, the telephone number of the transfer destination is input, and finally, r#1 is sent to indicate the end of the operation.

The PB tone is determined by transmitting the telephone number and r#1 data from the telephone lines L1 and L2 to the CPU 5 via the transmitting/receiving separation circuit 2, and if it is correct, the r command is received from the voice response circuit 15. rPlease hang up 1 will be announced.

Then, put down the phone and end the operation.

This operation generates a busy tone of 400 Hz, and when this busy tone is read by the CPU unit 5, a line disconnection instruction is output from the CPU interface circuit 4 to the line relay circuit 13 to open the line.

In addition, since the CPU unit 5 memorizes that the command has been input in the memory dial memory 8, after the control timer circuit 6 has counted a predetermined time, it issues an instruction to the line relay circuit 13 to close the line, thereby dialing After the tone is sent and the dial tone is determined by the CPU unit 5, the transmission/reception circuit 2 sequentially uses the forwarding destination telephone number in the dial selection circuit 11, the dial circuit section 10, and the memory circuit dial memory 8 as a PB)-tone. It is sent to telephone line L1, L, via .

By storing the PB)--in the memory of the exchange, the next call can be transferred to the forwarding destination.

Reference numeral 19 is an external control interface circuit, which is equipped with a telephone set including a sound collection microphone 20 and a loudspeaker circuit 21, and a sensor 22 installed on a door or window (if a door or window is opened or a fire occurs, each sensor will be activated). When activated, you can know from a remote location via the phone.

Therefore, it has the advantage of being useful for crime prevention and disaster prevention.

[Effects of the Invention] The present invention is provided with a microcomputer, and the microcomputer determines whether or not a predetermined operating procedure is being followed. However, since the system ignores this and waits for the correct operation from the user, there is no need to restart the operation from the beginning as in the past.

In addition, since it is equipped with a microcomputer, there is a control timer function that automatically sends data at a specified time, a shortcut operation function that allows you to register multiple forwarding destinations in advance and change them with a simple touch, and a quick operation function that allows the operator to know which operation procedure to perform next.
