Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a telephone control system that remotely controls the operation of a load using a telephone.

"Prior Art" Recently, telephone control systems have been put into practical use that remotely control the operation of loads such as air conditioners at home using push-button telephones from outside the home. The system is used to control the operation of the load as follows: A user who is away from home dials home to call the telephone control device.Then, when the telephone line is connected to the telephone control device, , a password to identify the user and a command signal to control the operation of the load are input using a push button and sent to the telephone control device.In the telephone control device, the password is set in advance in the telephone control device. The telephone control device checks whether the number matches the PIN number, and when it matches, accepts the command signal input after the PIN number and controls the operation of the load according to this command signal.This telephone control device controls the operation of the load. It monitors whether or not the load has been controlled, and when the load is controlled, a response tone is sent back to the user indicating that the load operation control has been completed.Then, when the user confirms this response tone and hangs up the handset, the load Operation control ends.

[Problem to be Solved by the Invention 1] By the way, there is a problem in that the telephone control device is connected to the telephone line via a protector and a disconnector, and wiring work is time-consuming.

The present invention has been made in view of the above-mentioned points, and its purpose is to provide a telephone control system that facilitates construction work.

[Means for Solving the Problems 1] In order to achieve the above object, the present invention incorporates a disconnector for inspecting telephone lines in a telephone control device.

[Function] By incorporating the separator into the telephone control device as described above, the present invention enables construction by simply connecting the telephone control device to the telephone line via the protector, simplifying the construction work. The aim is to

[Example] An embodiment of the present invention is shown in FIGS. 1 to 4.

As shown in FIG. 1, the telephone control system of this embodiment includes
This is to control the operation of the JEMA-compliant load via the JEMA (referred to as ) B. The I FUB is equipped with a JEMA Umejun home automation terminal, and as shown in Figure 4, it is connected to the load via a connection cable 15, receives control signals from the telephone control device ff1A, and controls the operation of the load. , sends back to telephone control device A a signal indicating the operating state of the load.

In this telephone control device A, an incoming call detection circuit 1
The incoming call is detected by detecting the ringing signal sent from the telephone office, and when a certain period of time has elapsed since the incoming call was detected by the incoming call detection circuit 1, the direct current connection circuit 2 disconnects the telephone line l. Close. A diode bridge DB is provided between the incoming call detection circuit 1 and the telephone line L, so that the telephone control device A can be connected to the telephone line L without polarity. The operation of this DC closing circuit 2 is controlled by a signal processing circuit 3, and the time (response time) until the telephone line fill is closed is set by a response time switching circuit 4. That is, this telephone control device A is connected to the telephone line 1 in parallel with a normal telephone, and if the telephone control device A answers first, it will no longer be possible to make a call using the telephone. Therefore, the response time of the telephone control device MA must be set appropriately so that the telephone can respond.

When the DC connection circuit 2 is closed, the telephone control device A becomes ready for reception. In addition, the user inputs a personal identification number for identifying the caller as the user and a command signal for controlling the load operation by operating a push button.

This push button signal (hereinafter abbreviated as P'B signal) is passed through a low pass filter 11 and a transformer T to the P'B signal.
The signal is input to the signal detection circuit 5 and detected. The PB multiplied signal detected by the PB signal detection circuit 5 is compared with a number set in the password setting circuit 6 by the signal processing circuit 3.

When this PB multiplied signal matches a certain password with a certain number set in the password setting circuit 6, the command signal following this password is accepted. In other words, the load is not controlled by anyone other than the user. The signal processing circuit 3 then controls the control circuit 7 based on the command signal.
The operation of the load is controlled (activated or stopped) by the output of the control circuit 7 via IFUB. The operating state of the load at this time is monitored by the monitor circuit 8, and the monitor circuit 8 returns a monitor signal indicating the operating state of the load to the signal processing circuit 3. The signal processing circuit 3 learns the operating state of the load from the monitor signal, and displays the operating state of the load using the operation display circuit 9. At the same time, the signal processing circuit 3 sends a response sound indicating the operating state of the load from the response sound sending circuit 10 to the user side. The telephone control device A is powered by a commercial power source (AClooV), and the power supply circuit 12 generates a DC power source for operating each of the circuits described above.

Incidentally, in this embodiment, in addition to the above basic configuration, a disconnector 13 for inspecting the telephone line I is built into the telephone control device ffA. This disconnector 13 is composed of a switch SW that connects or disconnects the telephone control device A from the telephone line #I2.This switch SW disconnects the telephone control device A from the telephone line β, and connects the telephone line L with direct current. Close the connection and check the telephone line ρ.

If the disconnector 13 is built into the telephone control device A in this way, it becomes unnecessary to install the disconnector 13 and to connect the disconnector 13 to the telephone control device A and a safety device (not shown). , construction work becomes easier. In this way, by using the disconnector 13 as a side job, the modular outlet 14 to which a telephone is connected is also built into the telephone control 1IifA.
