Abstract

PURPOSE:To improve an appearance by incorporating a controller main body to a controlled load by providing a connecting means to be connected to the controlled load and a telephone circuit at one part of the moduled controller main body. CONSTITUTION:A controller main body 1 to control the controlled load by means of a signal transmitted through a telephone circuit is moduled, and a connector 4 connected to the controlled load and the telephone circuit is provided on one part of the controller main body 1. In such a manner, by providing the connector 4 connected to the controlled load 5 and a telephone circuit (l) at one part of the controller main body 1, the controller main body 1 can be assembled to the controlled load by connector-connection, the appearance can be improved, and the connector is prevented from an obstacle.

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,
They are generally built into control panels, etc., or are tap-type devices that are attached to power outlets, and are installed in an exposed manner.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, since it is an exposed type, there are problems in that it looks bad and may protrude from the wall surface and become a hindrance.

The present invention has been made in view of the above points, and its purpose is to provide a telephone control device that can be built into a controlled load, has a good appearance, and does not get in the way. It is about providing.

[Means for Solving the Problems] The telephone control device of the present invention has a control device main body that controls a controlled load by a signal transmitted through a telephone line as a module, and the controlled load and the control device are installed at one place in the control device main body. It is equipped with a connector for connecting to a telephone line.

[Function] The present invention is constructed as described above, and a connector connected to the controlled load and a telephone line is provided at one place in the modularized control device main body, and the control device main body is connected to the control device main body in one place. It is now possible to provide a telephone control device that can be integrated into the control load to provide an aesthetically pleasing and unobtrusive telephone control.

[Embodiment] Fig. 1 shows an embodiment of the present invention, in which two printed circuit boards 2a are mounted with a control device main body 1 that controls a controlled load 5 by signals transmitted through a telephone line β.
. A controlled load 5 and a telephone line β are connected. The end cover 3b of the case 3 is formed with an opening 6 that exposes the connector 4, and the side surface of the case body 3a has an opening 6 with which an engaging piece 7 protruding from the end cover 3b is engaged. A matching hole 8 is bored.

Figure 2 shows the configuration of the control device main body 1.
It is formed by a signal processing section 10, a latching relay 11 equipped with a main contact ra for load control and an auxiliary contact rb for monitoring, a switch 12 for switching response time, and a switch matrix 13 for setting a four-digit password. There is.

Further, as shown in FIG. 3, the signal processing section 10 includes a CPU
an arithmetic processing circuit 15, an incoming call detection circuit 16 that detects an incoming signal, a DC closing circuit 17 that connects the DC circuit of the telephone line l, a low-pass filter 18, a PB signal identification circuit 19, and a response sound. It is formed by a sending circuit 20, a relay drive circuit 21, and a monitor signal input circuit 22.

Here, when the incoming call is detected by the incoming call detection circuit 16, the arithmetic processing circuit 15 controls the DC closing circuit 17 to automatically answer the call after a predetermined response time set by the switch 12, and the call is answered automatically. The PIN number transmitted via line l and identified by PB signal identification circuit 19 is sent to switch matrix 1.
3, it is determined whether the password matches a preset four-digit password, and a load control signal is then generated based on the received load control data. The relay drive circuit 21 is controlled by this load control signal,
The latching relay 11 is turned on or off, and the controlled load 5 is controlled by the main contact ra. At this time, the state of the auxiliary contact rb is taken into the arithmetic processing circuit 15 via the monitor signal input circuit 22, and the arithmetic processing circuit 15
In this embodiment, a module is used to control the response tone sending circuit 20 and send a response message or response signal indicating the operating state of the controlled load 5 to the telephone line l via the low-pass filter 18. A connector 4 connected to the controlled load 5 and the telephone line p is provided at one location of the control device main body 1, and the control device main body 1 can be incorporated into the controlled load 5 by connecting the connector to improve the appearance. At the same time, it can be kept out of the way.

FIG. 4 shows another embodiment in which the signal processing section 10 of the control device main body 1 is made into a hybrid IC, which makes it possible to further simplify the mounting of circuit components.

[Effects of the Invention] The present invention is configured as described above, and is provided with a connection means to be connected to a controlled load and a telephone line at one place in a modularized control device main body. can be incorporated into the controlled load to improve its appearance and provide an unobtrusive telephone control device.

[Brief Description of the Drawings] Fig. 1 is an exploded perspective view of an embodiment of the present invention, Fig. 2 is a block circuit diagram of the same as above, Fig. 3 is a block circuit diagram of essential parts of the same as above,
FIG. 4 is a cutaway perspective view of a main part of another embodiment. 1 is a main body of the control device, 2 is a printed circuit board, 3 is a case, 4 is a connector, and 5 is a controlled load.
