연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A passive wireless sensor and control transmitter subsystem is provided for operating irrigation or other hydraulic system. The system includes a master module unit hardwired to and in communication with an existing hydraulic system controller, and a field module unit that is hardwired to and in communication with field electromechanical control devices such as valves, solenoids and servo motors, and field sensors indicating, for example, atmospheric conditions. The master module unit and field module unit communicate with digital wireless communication and can act as a simple wireless bridge providing pass through data connectivity. The master module and field module units are capable of digitizing input signals from the devices to which they are hardwired and transmitting them to the opposite module; they are further capable of recreating the digitized signals received back into the analog form to reproduce the original input signal and communicating it to the device to which it is hardwired. Full duplex communication enables remote sensors to be hardwired to the field modules unit rather than directly to existing control apparatus, as well as being able to transfer valve, pump and relay status back to existing control apparatus. One embodiment enables the subsystem to receive sensor inputs and process them accordingly even though the hydraulic control system may not be capable of utilizing them. Supplemental functionality may be added to an existing hydraulic control system by including the WSCX and its system features of sensor functionality and control.
