Abstract

PURPOSE:To execute control operation without generating any trouble even when an automatic answering telephone set is connected to the same telephone line in parallel by setting up the continuing time of a terminating signal required for the response of an automatic terminating means to a value longer than the response time of the automatic answering telephone set. CONSTITUTION:In a telephone control equipment 1, the continuing time of a termination signal required for the response of the automatic terminating means formed by a termination signal detecting circuit 21 and an arithmetic processing circuit 34 is set up to a value longer than the response time of the automatic answering telephone set. When the coincidence of an identification number is obtained within a prescribed time from the detection of the termination signal, the circuit 34 outputs a load control signal.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone control device that remotely controls a load via a telephone line.

[Prior Art] Conventionally, this type of telephone control device that remotely controls a load via a telephone line has an automatic call termination means that closes the telephone line when an incoming signal (calling signal) reaches a predetermined duration. , a PIN number matching determination means for detecting whether a PIN number sent as a PB double signal via a telephone line matches a preset PIN number, and a load control signal for controlling a controlled load when the PIN numbers match. It consisted of a load control means that outputs

Here, the above-mentioned duration time is set to, for example, 45 seconds, and when the incoming signal continues for 45 seconds, the automatic call receiving means operates and the telephone control device responds, and the telephone control device responds to the call, which is set in advance from the control side telephone. When the PIN code is sent as a PB signal, it outputs a load control signal that reverses the operation of the controlled load (on-off, off-on), and remotely controls the controlled load. . At this time, a monitor signal indicating the operating status of the controlled load is sent back to the control side via the telephone line, allowing the control side to confirm whether the controlled load has been controlled normally. It has become.

[Problem to be Solved by the Invention 1] However, in the above-mentioned conventional example, there was a problem that control operations could not be performed when answering machines were installed in parallel on the same telephone line. In other words, the answering machine is equipped with an automatic call receiving means that answers the call when the incoming signal continues for about 10 seconds. There was a problem in that the receiving device did not work and could no longer accept pin numbers or control signals, making it impossible to perform remote control using the telephone line, and making it impossible to install a telephone control device and an answering machine on the same telephone line. Ta. Incidentally, if the response time of the telephone control device is made shorter than the response time of the answering machine so that the telephone control device responds first, an inconvenience arises in that the answering machine "S" telephone stops working.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a telephone control device that can perform control operations without any trouble even when answering machines are installed in parallel on the same telephone line.

A manual switch SWd for controlling is provided.

The operation of the embodiment will be specifically explained below.

The operation of the telephone control device 1 in the case where an answering machine is not installed in parallel is the same as in the conventional example, and when an incoming call signal is detected by the incoming call detection circuit 21, the automatic call receiving means responds to this incoming call signal. When a predetermined duration time set in advance by the time switch SWb is reached, the DC connection circuit 22 closes the DC circuit to place the telephone #ia in a talking state. When the PB double signal is detected by the PB signal detection circuit 27 in this state, the password matching determination means formed in the arithmetic processing circuit 34 detects the password sent by the detected PB double signal and the password setting. The switch SWa determines whether the password matches the preset password, and if the password matches, the load control means generates a load control signal Vc and sends it to the control signal output circuit 28 via the upstream signal input/output circuit 30. output to HA outlet 3. The controlled load 2 connected to this HA outlet 3 is a load such as a JEM-A standard compliant air conditioner, and its operating state is reversed (on-off, off-on) by the load control signal Vc. At this time, the monitor signal Vm indicating the operating state of the controlled load 2 is inputted to the arithmetic processing circuit 34 via the signal input/output circuit 30 and the monitor detection circuit 29 to determine the operating state of the controlled load 2. A response tone indicating the response tone is generated and transmitted to the telephone line Mη via the sound signal amplification circuit 26, the response sound transmission circuit 25, and the low-pass filter 24.

On the other hand, if answering machines are installed in parallel on the same telephone line
10 seconds), the answering machine's automatic answering means operates to close the telephone line, send an answering message, and if necessary, the message recording means operates to call the other party. Record a message from the side. At this time, when an incoming call signal is detected, the response control means of the telephone control device 1 keeps the PIN number matching determination means and the load control means in operation for a predetermined period of time (for example, 3 minutes), and
It is possible to install a signal receiver. In this state, the password is transmitted using the PBM code, and if the password matches, the load control signal Vc is output and the aforementioned control operation is performed. If the incoming signal is not a call for control purposes but a normal call and the answering machine is performing the main operation, the PIN code match determination means and the load The operation of the control means is stopped after a predetermined time, and the controlled load 2 is not controlled. Note that the automatic call receiving means of the telephone control device 1 does not need to operate because the telephone line #lt is released by the automatic call receiving means of the answering machine.

[Effects of the Invention] The present invention is configured as described above, and the duration of the incoming signal required for the automatic call receiving means to respond is set to be longer than the response time of the answering machine, and the duration of the incoming call signal is set to be longer than the response time of the answering machine. The PIN number determining means and the load control means are operated only when the PIN number matches within the predetermined time period, so that the load control means outputs an output even if the answering machine answers first. Since the control operation is enabled by operating the PIN code determination means and load control means for a predetermined time while the telephone line is closed, the control operation can be performed even if an answering machine is installed in parallel on the same telephone line. The effect is that it can be performed without any trouble.
