Description

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

[Prior Art] Conventionally, a password using a push button signal (PB double signal or other signal) is transmitted through a telephone line, and when the password matches a preset password, the controlled load is activated. A telephone control device is provided which is adapted to control a telephone control device, which is used as part of a home automation system,
It was generally installed in large TN discs, etc., and had an exposed cast.

[Problems to be Solved by the Invention] However, since the above-mentioned conventional example is an exposed installation type, it cannot be buried in the wall using an embedded box, resulting in poor appearance and There was a problem that the construction was troublesome because it was not possible to do advance wiring. Furthermore, since the controlled load was connected to the non-voltage output terminal provided on the device body via a power supply, special wiring was required for load control.

A power control outlet 12 is provided which is connected to T4. Also, a light emitting diode LED1 displays the load status, and a light emitting diode LED2 displays the telephone line connection status.
and a switch SW for manual load operation are exposed on the front surface of the device body 1. FIG. 3 shows a schematic configuration of a remote control system using a telephone control device 16 according to the present invention. A push-button switch emitted from the telephone is transmitted to the telephone control device 16 via the telephone line.
Received at. The telephone control device 16 takes in this control signal, turns off or on the AC power supplied to the power control outlet 12 when the password matches, and connects the controlled load 14 connected to the power control outlet 12 via the power plug 13. Turn on or off.

The line on/off display circuit 34 displays the line on/off status.

The power supply circuit 32 and the power supply control outlet 12 are connected to an AC power source through terminals T 3 and T − provided on the back surface of the container 1 .

A password matching determination means detects whether the password transmitted via the telephone line matches a preset password, and a control signal is received when the password matches to control the latching relay RY. A signal processing means for outputting a control signal and returning a response sound formed based on the relay operation detection signal to the control side is formed by the signal processing section 31.

The operation of the embodiment will be specifically explained below.

Now, when an incoming signal is detected by the incoming signal detection circuit 18,
In the signal processing section 31, this incoming signal is processed by the response time switch S.
When the predetermined duration time set in advance in W2 has elapsed, the DC circuit is closed in the DC connection circuit 19 to put the telephone line into a talking state. When the PB double signal is detected by the PB signal detection circuit 22 in this state, the PIN number matching determination means formed by the signal processing section 31 detects the PIN number sent by the detected PB double signal and the PIN setting switch. SW a
= SWd determines whether the password matches the preset password, and if the password matches, a control signal is created and an output signal is sent to the load control relay circuit 54, which activates the two-winding type latching relay RY. Invert.

In this way, the contact r of the latching relay RY is turned on and off.
Since it is inserted between the power control outlet 12 connected to the latching relay RY, the on/off state of the controlled load 14 can be set according to the operation of the latching relay RY.

The state of contact r of latching relay RY is sent back to signal processing unit 31 via relay operation detection circuit 26, and it is checked whether latching relay RY has operated reliably. When the operation is confirmed, the signal processing unit 31 sends a response signal back to the telephone line via the voice response circuit 21 and the low-pass filter 20.

In the manner described above, the controlled load 14 can be controlled in response to the password transmitted via the telephone line. Of course, the controlled load 14 is controlled by the switch SW
It can also be done manually by pressing +, and the on/off state of the controlled load 14 is displayed by a light emitting diode L1. Also, use the switch SW to determine whether or not to connect this circuit to the telephone line.
3 and is connected to the telephone line, the light emitting diode LED2 lights up.

By the way, when installing the telephone control device 16 in the embedded box, it can be easily installed using the ready-made standardized mounting frame 2, and the construction can be easily performed, and the appearance can be improved by the embedded arrangement. It looks like this. Additionally, since wiring can be done in advance during new construction, construction can be done more easily.

Although the operating section in the above embodiment was provided with a lid 11, it may be covered with a decorative plate 15 as shown in FIG.
