Abstract

RS485 bases networking of distributed embedded systems is most effective as every microcontroller based embedded system has built-in serial communication interface. Establishing a network connecting heterogeneous microcontroller based system become quite simple when RS485 based communication is used. However RS485 suffers from too much of overhead due to the need for transmitting the addresses along with Data. HUB based RS485 based communication eliminates the needs for transmission of the overheads. In this paper HUB based RS485 based networking of heterogeneous embedded systems that suits to a pilot project that monitors and controls the temperature within a Nuclear reactor system has been proposed. Many other related inventions that include Architecture of Message flow, addressing the devices on the network, and data packet design related to the pilot project have also been presented.
