Recently, attention has been paid to standby power cut-off devices due to energy saving, electronic safety cut-off devices for safe use of electric power, and electronic power meters and lighting control devices for remote meter reading in the home network field.

However, the conventional lighting control device, standby power cut-off device, safety circuit breaker (leakage, overload, short circuit), electronic electricity meter are composed of separate products, and the installation places are different, and consumers have to purchase and install each device separately. There was a ham. This led to difficulties in construction and management. Therefore, research has been conducted on devices in which some functions of the device are integrated or converted to electronic rather than mechanical methods. Korean Patent Laid-Open Publication No. 2000-0006898 discloses a power input unit for inputting power, detecting power or amount of power input through the power input unit, and detecting detected power or amount of power to reach a set reference power or power amount value. In this case, the control unit transmits a control pulse signal to selectively supply or cut off each power load according to a preset control order therein, and receives the control pulse signal transmitted from the control unit, and accordingly, the power is supplied to a plurality of power loads. Disclosed is an electronic power meter having a power load control function, comprising: a control signal transmission / reception unit configured to transmit an open / close signal for supplying or blocking a signal.

On the other hand, recently, thanks to the widespread use of the Internet and the development of communication technologies, home networks and home automation fields for connecting and utilizing various electric / electronic devices and communication devices in homes and offices have been attracting attention. In the field of home network or home automation, standardization and technology development are being actively conducted for each communication method such as wired LAN such as omePNA or IEEE1394, wireless LAN using HomeRF, Bluetooth, IrDA communication, and so-called Lonwork-based building. Automation devices and the like are also attracting attention.

Integrated standardization of home network and home automation related technologies is still inadequate, and home servers required to perform comprehensive home automation control that can support various protocols and support remote control and home control using wired / wireless communication line or Internet network.

On the other hand, a control device capable of integrated management of home appliances distributed in a home corresponding to various communication protocols has also been developed. For example, Korean Patent Registration No. 10-0369318 describes a control device for a home network that can support all communication protocols such as IEEE1394, USB, IrDA, X-10, and Lonwork. Republic of Korea Patent No. 0133356 relates to a 'home and office integrated management electronic system' using a monitoring and alarm system connected to the Pyro-electric detector, gas detection and / or fire detection sensor, telephone / wireless communication / power line communication It describes an integrated management transcription system including a communication system for transmitting and receiving data, a control system, and a power management system that protects data of a specific electronic device in case of a power failure.
