DESIGNING OF EMBEDDED SOLUTION FOR SERIAL ASYNCHRONOUS TO ANALOG RESOLVER FORMAT CONVERSION

Abstract

A marine vessel platform is fitted with sensors and equipments of diverse origin which are required to work in tandem in order to enhance its operation capability. However, due to incompatibilities in respect of data formats and protocols that are used, these equipments/ sensors cannot be interfaced directly. Presently, some systems are digital type, and some are analog type. Therefore, this project focuses on the design and development of embedded solution for Serial Asynchronous (Digital) to Analog Resolver format conversion for transmission of Roll and Pitch Angle and it also provides interfacing of digital and analog Resolver systems. An embedded board was designed using Cadence OrCAD proprietary software and it was developed using microcontroller 8051, Digital to Resolver converter modules, Low power operational amplifiers and some other required components. This electronic interfacing embedded board converts the Digital input contains Roll and Pitch angle into Analog Resolver types of output. It was tested using simulated Roll and Pitch angle created with the help of COM Port Toolkit application software and the output of this embedded interfacing solution was measured on Angle Position Indicator (API) and on an oscilloscope.
