A RECONFIGURABLE SENSOR NETWORK FOR VEHICLE SYSTEM AND ITS RELIABILITY PREDICTION

This paper suggests a reconfigurable sensor network (data bus) which is well suited for telemetry mission of rockets and launch vehicles. Reconfiguration of sensors’ channel information can be achieved without additional software and hardware. The proposed network consists of a central unit and multiple remote units with RS-485 data bus. Since those units need only an FPGA and a programmable ROM to be implemented, the network can provide minimum costs and high reliability. And this paper also presents reliability prediction result of a unit based on MILHDBK-217F and Monte Carlo simulation.
