This invention relates to a home bus compatible telecontrol system that controls the home bus.

BACKGROUND OF THE INVENTION FIG. 3 is a diagram showing an example of a system configuration for realizing telecontrol via a public telephone line in a conventional in-home bus type network. In Figure 3,
Reference numeral 5 indicates an information signal line of a balanced pair cable used for information data transmission or office line communication; 6 indicates the information signal line 5;
This is a balanced bare couple control signal line used for exchange control requests and transmission of low-speed data between the subscriber telephone line 4 and the subscriber telephone line 4. 1 is a home bus control device (MBC), which connects the subscriber telephone line 4 and the news signal line 5;

An RBC exchange circuit 15 that performs all disconnection exchanges, a PB reception demodulation circuit 11 that demodulates the PB double signal received from the subscriber telephone line 4, and a synthesized voice is sent to the subscriber telephone line 4 according to the analysis result of the PB received demodulated signal. a voice synthesis generation circuit 13 that performs the communication, a controlled device 3 equipped with a communication control function connected to the network via the control signal line, and/or an information device 2 that transfers various data using the information signal line. a transmitting/receiving circuit that transmits and receives control signals between the FB receiving and demodulating circuit 11, and a PB double signal analysis and switching circuit 15, which is demodulated by the FB receiving demodulating circuit 11; Transmission/reception circuit 14. It is composed of an HBC control section 12 that controls a speech synthesis generation circuit 13.

Problems to be Solved by the Invention In such a conventional system, the home bus control device is configured with a teleconverter service function, so the flow from receiving a call from the subscriber telephone line to teleconverter control is simple. On the other hand, control of controlled devices such as air conditioners connected to the bus is also performed by control signals sent to the control signal line by the home bus control device, and the system form is centralized by the home bus control device. It has to be controlled. This concentrates the load on the home bus control device whose main function is bus management, which goes against the distributed control that should be an advantage of a bus network, and also lacks flexibility in system construction.

The present invention has been made in view of the above points, and has a bus communication function on the home bus, and is capable of automatically closing a DC loop when receiving a call and generating voice synthesis, which was conventionally performed in a home bus control device. Distributed control is realized by connecting a telecontrol device that performs such operations.

Means for Solving the Problems In order to solve the above problems, the present invention provides DC loop closure control and FB reception demodulation processing during automatic call reception.

A telecontrol device (telecontroller) that has functions for PB analysis processing, speech synthesis transmission processing, and control of controlled equipment is installed as one terminal connected to the home bus, and when the telecontroller receives an incoming call notification from the home bus control device, In addition to capturing the information signal line used for speech synthesis transmission and PB reception, the DC loop is fully closed, and the PB double signal received from the public telephone line is demodulated and analyzed, and based on the analysis results, it is sent to the controlled device. control signals, or send out voice synthesis to public telephone lines via information signal lines.

Effects The above sentence structure realizes processing decentralization of the home bus control device and bus connection device when performing telecontrol services in a home bus type network that can be connected to a public telephone line, and also provides heavy telecontrol for the home bus. By introducing the device, functions can be easily added as a bus application even to bus systems that do not support telecontrol.

Embodiment FIG. 1 is a block diagram showing an embodiment of the home bus compatible telecontrol system of the present invention.

In addition, the same numbers in Figure 1 are used for the same items as in Figure 3. Granted.

In FIG. 1, reference numeral 40 denotes a home bus compatible telecontrol device, which includes a transmitting/receiving circuit 41 for transmitting and receiving control signals via a control signal line 6, an information signal line 5, a PB reception demodulation circuit 44, or a voice synthesis generation circuit 45. It is composed of a switching circuit 42 that performs connection and disconnection, and a telecontroller control section 43 that analyzes PB reception signals and generates control signals (control commands) for the controlled device 3. Further, FIG. 2 is a diagram showing an example of a communication sequence on the home bus when performing the telecontrol service according to the present invention in the configuration of FIG. 1.

In FIGS. 1 and 2, when the home path controller (MBC) 1 detects an incoming call from the subscriber telephone line 4,
If it is in teleconference mode (for example, an absentee mode is set by a switch, etc.), HBCl sends an incoming call command to all connected devices on the bus, and then sends a call command to telephone 2 to indicate that a call is being received. Send status. Upon receiving the incoming call command, the telecontrol device 40 transmits the HBC
It sends an incoming call response command to inform that it is possible to receive a call, and also sends a teleconverter command to notify that teleconverter control is possible (automatic incoming call response of the telecontrol device). The above-mentioned automatic incoming call response is performed when an absent mode command is sent in advance from the MBC via the control signal line when the teleconference mode is set; otherwise, only normal incoming calls to the telephone set 2 are performed.

When the HBCl receives all the teleconference commands from the telecontrol device 40, it secures the information signal line and notifies all devices on the bus that it has received an incoming call response (incoming call response confirmation command).

Further, it sends the telephone status to the telephone 2, and stops ringing due to an incoming call.

HBCl connects the subscriber telephone line 4 and the previously secured information signal line 5 (switching circuit ON), and also issues an information signal line connection command to connect the information signal line 6 at the switching circuit 42 on the telecontrol device side. send. In the telecontrol device 4o, after connecting the information signal line 5, the DC loop is closed.

Through the above procedure, a link between the subscriber telephone line 4 and the telecontrol device 40 is established, and thereafter, PB double signal voice synthesis data will be exchanged within the bus via the information signal line 5. When the teleconference starts, the voice synthesis generation circuit 45 of the telecontrol device 40 sends a message such as [Please enter your password].The telecontrol device 40 analyzes the sent PB demodulation signal and responds to the analysis result. If the received PB demodulated signal is a device control command,
A control command such as ON10 FF is sent to the corresponding device (air conditioner in FIG. 2) 3 via the control signal line 6.

After the information signal line 5 is provided to the telecontrol device 4o and the link is established, the HBC 1 is responsible for transmitting and receiving data between the telecontrol device 40 and the subscriber telephone line 4 until the service is terminated. It becomes possible to perform other processing without any involvement.

Furthermore, if the function up to link establishment is added to HBCl, the telecontrol device of the present invention can be installed on the bus.
Just by connecting, you can easily expand 7 bus stems that do not support telecontrol to support telecontrol.

Effects of the Invention According to the telecontrol system of the present invention, the home bus control device only performs line exchange between the subscriber telephone line and the information signal line of the bus, and control regarding services is performed by the telecontrol device, so that the load on the bus application is reduced. In addition to achieving decentralization, the functions of the telecontrol service depend only on the telecontrol device, making it easy to expand the service and allowing for flexible support in system construction.
