Abstract: A light-powered data acquisition and control system immune to electromagnetic interference employs smart sensors in a network configuration capable of decentralized communication. A smart sensor with integral transducer encloses a microprocessor, fiber optic transceiver, and photovoltaic converter within a Faraday cage. Optical fibers link plural sensors for duplex communication with a fiber optic splitter, which transmits high intensity light to the converter for powering the sensors. The sensor converts analog input from the transducer into bit packets for fiber optic transmission to the network via the splitter. Firmware in the splitter converts the bit packets to network protocol and vice versa enabling data communication among sensors, splitters, and control receivers. Verification algorithms for testing sensors are run automatically by the microprocessor or through commands issued via the network. Mnemonics stored in the sensors provide automatic updating of system configuration.
