The present invention relates to a home automation system, and more particularly, to a remote call method that allows a security control station to manage the home automation system and a remote call.

In general, the home automation system is a system that remotely controls home appliances used in the home by connecting a telephone line, or automatically detects crime prevention, disaster prevention, gas, etc. to facilitate the life of the home.

However, there is a problem in that a call cannot be made when a family of a family having a conventional home automation system needs to go out and require a call with a security control station that manages the home automation system at a remote location. Accordingly, an object of the present invention is to provide a remote call method that allows a remote control to manage a home automation system and a remote call.

The remote call method of the home automation system according to the present invention for achieving the above object comprises the steps of: checking whether the home automation system is called from the remote telephone through a trunk line when the home automation system is pressed out; If it is checked that it is called from the remote telephone and checks whether it is in the outgoing mode, and if it is checked that it is in the outgoing mode, it goes to the outgoing standby state; When the remote telephone checks the call request with the security control station managing the home automation system and checks that the call is the call request, the process of connecting a call with the security control station: detecting that a call termination key is input and inputting the call termination key. If it is checked that the remote phone and the security management It characterized by the ends constituted by any process for the call connection to the.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a home automation system according to the present invention. The memory 110 includes an outgoing mode area and a remote call program, and the key input unit 120 includes an outgoing selection key and a numeric pad, and generates key signals corresponding to the input of the keys. The central processing unit 130 is connected to the key input unit 120 to process a function corresponding to the key signals, and controls the overall operation required for the remote call according to the remote call program.

The trunk line interface 140 is controlled by the central processing unit 130, receives a DTMF signal generated from the remote telephone 200, and makes a phone call connection with the home automation system. The network unit 150 is connected to the trunk line interface unit 140, the crime prevention management station 160, the handset 170, the central processing unit 130, and the like under the control of the central processing unit 130, It forms a switching connection between the connecting line and the components.

The security control station interface unit 160 is located between the home automation system and the telephone 300 of the security control station to transmit and receive data with each other.

2 is a flowchart illustrating a remote call method with the security control station in the home automation system according to the present invention. Hereinafter, an embodiment of a remote call method according to the present invention will be described in detail with reference to FIGS. 1 and 2. First, in step 400 of FIG. 2, the central processing unit 130 checks whether the outgoing selection key is input through the key input unit 120, and if it is checked that the outgoing selection key is input, generates the outgoing control signal indicating the outgoing mode. The process then proceeds to step 410. In step 410, the CPU 130 stores the outgoing control signal in the memory 110 and proceeds to step 420. In step 420, the central processing unit 130 checks whether the trunk line is called through the trunk line interface 140 and proceeds to step 430. In step 430, the central processing unit 130 checks whether the outgoing control signal indicating the outgoing state is recorded in the memory 110, and if the outgoing control signal is recorded, waits for 10 seconds in step 440 and then proceeds to step 460. Proceed. On the other hand, if the out control signal is not recorded in step 430 proceeds to step 450 and waits for 1 minute to proceed to step 460. In step 460, the central processing unit 130 connects the trunk line interface unit 140 to the trunk line, and then proceeds to step 470. In step 470, the CPU 130 checks whether the DTMF signal generated from the remote telephone 200 is input through the trunk line interface 140, and then proceeds to step 480 when the DTMF signal is checked. In step 480, the central processing unit 130 connects the telephone 300 of the security control station and the remote telephone 200 through the security control station interface unit 160, and then proceeds to step 500. In step 500, the central processing unit 130 checks whether the call is terminated by checking whether the remote telephone 200 and the telephone 300 of the security control station are terminated through the security control station interface unit 160. In step 510, the remote call is terminated by ending the CO line call. As described above, the present invention has an advantage of making a call from a security control station and a remote site that manages the home automation system.
