DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control method of a home automation system, and more particularly to a call control method of a home automation system having a security room communication function for making a call between each home and a security room.

[0002]

2. Description of the Related Art In general, a home automation system includes a central office call function for making a telephone call to the outside through a local line, an automatic answering function in which the system automatically generates a message in response to an external call, and a home automation system. Some have a remote control function capable of playing back a message that has been received while absent through an office line, including a response message.

On the other hand, in a condominium or the like, if a security room is provided for a security guard at the entrance of the condominium, etc., separately from a management room for managing the whole, the home automation system is separate from the circuit for the office line. Security room line circuit, and provides a security room communication function for making a call between each home and the security room. Usually, the security room communication function by the security room line circuit is provided as a separate function independent of the above-mentioned various functions using the office line, and there is no relation between the operations of the two.

[0004]

In the control method of the conventional home automation system as described above, a telephone is usually directly called from outside to a security room where a telephone for a central office call is not separately provided, and the telephone is connected via the office line. I can't talk to the security room. In other words, there is no relation between the operation procedure of the security room communication function and the operation procedure of the function using the office line, and these mutual functions cannot be linked. Therefore, the present invention provides a call control method of a home automation system that enables a communication line to be formed from outside to a security room and enables direct communication with the security room.

[0005]

SUMMARY OF THE INVENTION For this purpose, according to the present invention, a step of forming a communication path in response to a call from an office line and a signal designating a security room call after the formation of the communication path are transmitted to the office. A home that includes a step of detecting whether a signal is input from a line, and a step of connecting a station line and a security room line to call a security room when a signal input designating a security room call is detected. A call control method for an automation system is provided.

More specifically, a step of forming a communication path in response to a ring incoming call from an office line and performing an automatic response, and, when a password is input from the office line in response to the automatic response, the input is performed. A step of checking whether the security code is correct; a step of detecting whether a signal designating a security room call is input from the office line when the security code is correct; and a case where a signal input designating the security room call is detected. Calling the security room by connecting the office line and the security room line. If the password is correct, it is preferable to send a guide message to the office line and wait for a corresponding signal input.

[0007] The present invention is a method of combining the office line communication function and the security room communication function originally possessed by the home automation system, and acquires a new function by changing a software processing procedure without adding hardware.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a home automation system to which the call control method of the present invention is applied.
The home automation system 2 has a control unit 4, an automatic response unit 5, a peripheral circuit 6, a network IC 8, a handset 10, a station line circuit 12, a security office line circuit 14, and lines 16 to 24 connecting these.

The office line circuit 12 includes a communication circuit for office line communication and a DTMF (Dual Tone Multi-call) during dialing.
Frequency) signal, and a DTMF receiver for sensing an externally input DTMF signal. This DTMF receiver also functions to sense DTMF signals from external key inputs in remote control mode, including security room calls enabled by the present invention.

FIGS. 2A to 2C are flowcharts showing a control procedure of the home automation system of FIG. 1 according to the present invention. This system executes the remote control function to play the message, record the answering message, transfer the incoming call, etc. through the office line by inputting the password and the "setting key" assigned to various functions from the automatic answering mode as in the past. I do. According to the present invention, the security room call function can be used in this remote control mode.

In step 28, when the home automation system 2 receives a ring from the outside through the local line circuit 12, a ring sound is generated a certain number of times, and then the automatic answering unit 5 enters an automatic answering mode to execute an automatic answering function. The operation of the unit 4 automatically sets the hook-off state.
In step 30, the control unit 4 controls the automatic response unit 5 to send out a voice response message, and enters a standby state waiting for an external message or input (key-in) of a predetermined DTMF signal. If the caller's message comes in this standby state, it is recorded, and if there is no input, the process proceeds to steps 40 → 42 after a certain period of time to end the call.

In step 32, when a password such as a four-digit number or symbol is input, in step 34, it is determined whether the password matches a previously registered password. If the password is correctly entered, the control unit 4 controls the automatic response unit 5 to send a voice message of "guidance for using the remote control function by telephone number" in step 36.

In step 38, when the "setting key" assigned to each function is input, the function requested in step 44 → step 50 is determined. Here, since the “setting key” assigned to the remote control function other than the security room call function is a numeric key or “*” key, if the key input in step 38 is a numeric key or * key, Move to step 52 for performing the function.

On the other hand, in order to execute the security room communication function by remote control, if the setting key "#" assigned to call the security room is inputted in step 38, step 50 is executed.
This is detected. Then, in step 54, the control unit 4
Drives the office line circuit 12 through the control line 16 and the security room line circuit 14 through the control line 24,
The central office line and the security room line are connected through the network IC 8 to set up a communication path between the caller and the security room.
Then, at step 56, a calling signal is transmitted to the security room.

At this time, if it is detected in step 58 that the handset 10 of the home automation system 2 has been lifted, in step 60, the connection between the central office line and the security room line is cut off and the security room is disconnected. Interrupt the call and connect the line to the handset 10.

On the other hand, if the handset 10 is not hooked off, it is detected in step 62 whether the set time has elapsed. If it is within the set time, the call signal of the security room is continuously generated and the process proceeds to step 66. If the set time has elapsed, the call is terminated and the process proceeds to step 64 where the process returns to the remote control mode. In step 66, the control unit 4 checks the presence or absence of a busy signal from the security room. If there is a busy signal, the control unit 4 ends the call and returns to the remote control mode. In step 64, if there is no busy signal, Then, the process proceeds to step 68 for confirming the communication path connection with the security room.

Through the above control procedure, step 7
If 0, talk between the external user and the security room.

[0019]

According to the present invention, it is possible to link the security room communication function with the operation of the function using the office line, thereby forming a communication line from outside to the security room. As a result, it is possible to make a telephone call directly from the outside to a security room in which a telephone for a central office call is not separately provided, and make a call with the security room through the office line. For example, it is easy to leave a child who has returned from school in the security room for a while, or to ask the security room to look around his room because he seems to have forgotten the key from the outside. It is convenient and convenient for crime prevention.
