We have been designed and developed a security system including home automation with control of electronic appliances. The system can detect intruders using infrared sensors and monitor rooms or offices in real time by web camera. The password was needed to enter a house or office. The operation of home electronic appliances also can be easy and remotely controlled by Internet. The system was designed by VHDL. The size of the fabricated system is small and it showed good performance.

This paper presents a systematic method of probing channel characteristics and communication reliabilities of home power line communication network applied to the Internet accessed control of home appliances. The effects of the three performance deteriorating factors, i.e., additive noise, channel attenuation, and intersymbol interference, can be systematically measured by applying the channel probing waveform in the frequency range from 100㎑ to 450㎑. Probability of bit error is derived with the probed channel parameters of the signal attenuation, noise and signal-to-interference ratio read in the frequency domain. The agreement between the derived probability of bit ewer and the measured probability of bit error support the validity of the proposed approach of probing home power line channel characteristics. The experimental results performed with the constructed test-bed applying the Proposed channel probing method and the operation reliability measurement of the overall networked system also support the feasibility of commercially deploying the PLC modem installed home appliances and their services for the Internet accessed home automation in densely populated residential apartment complexes.

These days, a lot of research has been in progress for a home automation system. In this study, the intelligent home automation system is developed for automatically controlling the temperature and illumination of the house. The difference with other research can be adjusted individually according to your taste and lifestyle of each individual, it is that it provides a more comfortable living environment through the accumulated lifestyle database. In addition, proposed system can use the mobile app to easily control the lighting devices, a electric fans, and heaters. Moreover the mobile app of proposed system offers function that allows you to search for residential environments statistics on their lifestyle.

The purpose of this paper is to build a system applicable to floriculture, hydroponics and vinyl house agriculture by a development of remote control equipments using programmable logic controllers (PLC). Remote factory automation and home automation systems have been developed and used due to the rapid progress in the fields of information and automation; however, the systems are so expensive that their applications have not been feasible in agriculture. So we have developed simple modules for PLC to replace the expensive conventional systems. The developed systems have potentials to be applied to automation systems in agricultural industry. Technologies for motor control, microprocessor, PLC programming and wireless interface are developed and implemented in the form of application modules of our systems, and our system is applicable to the remote form automation of floriculture and hydroponics.

세계는 지금 자동화로 간단없이 치닫고 있다. 사무자동화로 잘알려진 OA(office automastion), 공장자동화라 일컫는 FA(factory automation), 다소 생소하기는 해도 가정자동화라 할 수 있는 HA(home automation)가 이른바 자동화의 트로이카인데 이 가운데 가장 주목받고 있는 것은 역시 FA. 이러한 마당에 금성통신이 안양공장에 무인자동창고를 실현, FA에 성큼 다가서면서 자동화사업을 본격적인 영업종목으로 들고 나서 비상한 관심을 모으고 있다.
