A network system suitable for remote monitoring or remote control of equipments is provided. When an execution of a server-side object is requested from a client terminal device to a server, the server requests an execution of an equipment-side object to the equipment(s). The execution request of the server-side object from the client terminal device is performed by use of a first identifier assigned to the server-side object, and the execution request of the equipment-side object is performed by use of a second identifier assigned to the equipment-side object. Since the server has an identifier setting function of setting a correspondence relation between the first identifier and the second identifier, it is possible to reduce burden on the client terminal device, and flexibly cope with cases of exchanging and increasing the equipment(s) in the network system without considering specific identification information of the equipments such as IP address.

Network system

A network system is provided, in which a system change can be easily performed by adding or exchanging an equipment(s) to be controlled or monitored. The equipment has an object with an object identifier defined according to a service content provided by the equipment. Upon the receipt of a service request using the object identifier from a network device connected to the equipment via a network, the equipment executes the service defined in the object according to this service request. By assigning a same object identifier to objects of a plurality of equipments, it is possible to provide the same service from those equipments according to the service request performed from the network device by use of the same object identifier.

A voice control system for managing home electrical appliances includes a home agent server (HAS) connected to the home electrical appliances, a microphone and a speaker linked to the agent server through an in-house network. An transaction processing (TP) program runs on HAS and interprets the user's voice request to find a destined appliance and a manner of control the same, and performs the requested control to the destined appliance. The result is notified to the user by means of a voice message.

A setting apparatus and a setting method are provided for setting setting information including attribute information and interlocking operation information into an electric power line carrier communication terminal apparatus equipped with an electric power line carrier communication section for performing electric power line carrier communication through an electric power line of a commercial electric power source. The setting information is previously stored in a data storage memory, and an infrared transmitting section transmits the setting information stored in the data storage memory, directly to the electric power line carrier communication terminal apparatus using an infrared communication method.

An intra-premises communication system enables the use of a preinstalled wired transmission channels, yet allowing a particular communication system to be located at a desired region in the premises. The system comprises an exchange box adapted to be installed in the premises and provided with different interfaces for connection to different networks. A plurality of the wired transmission channels extend from the exchange box and terminate to receptacles which are installed in the premises and have common connectors. A plurality of indoor wireless terminals of different types are provided for use within the premises. A plurality of local transmitter-receivers of different types are provided in correspondence to the types of the wireless terminals. Each of the local transmitter-receivers is detachably and selectively mounted to the common connector of the receptacle for wired communication with one of the networks through the associated transmission channel. The local transmitter-receivers have individual antennas or the like member for wireless communication with at least one of the terminals. The exchange box includes a switch for connecting the transmission channels selectively to particular ones of the interfaces, thereby allocating local transmitter-receivers and the associated terminals to the different networks. The receptacles can be preinstalled in the like fashion as the conventional electrical receptacles so that a desired wireless communication system can be located at a suitable region simply by mounting the local transmitter-receiver of the selected type to the common connector of the receptacle.

Intra-premises communication system

A data transmission system utilizing a power line comprises a transmitter (1), a receiver (2) and a repeater (5) coupled to a power line (3). Control data including a start code in the form of a high frequency signal is transmitted from the transmitter (1) in superposition on an alternating current of the commercial power supply using the power line. The repeater receives the control data transmitted from the transmitter, thereby to store the control data in a memory responsive to the start code. The control data is then read from the memory after the lapse of a predetermined period of time and is retransmitted to the receiver in a predetermined level. The receiver receives the control data, thereby to control an apparatus being controlled such as a relay, whereupon the same transmits in a return manner the data representing a control state thereof. The repeater receives the data and transmits the same to the transmitter.

A transmitter connected to any phase of a 3-phase alternating current transmits a data subsequent to a lock signal in synchronism with the cycles of the phase. A receiver connected to any phase of the 3-phase alternating current receives a lock signal in synchronism with the cycles of the phase. The receiver receives each data after the receiver is synchronized with the transmitter using the lock signal. The synchronized relation is maintained, that is locked until each data transmission subsequent to a lock signal is terminated. The lock is released upon detection of an end signal added to the last portion of each data or a non-busy signal interval. In the case wherein a data transmission is repeated a plurality of times, a set of signals including a lock signal and a data is repeatedly sent out, interleaved with a non-busy signal interval.
