In this paper work are proposing some original solutions particular to the data transfer mean and protocols corresponding. The bus imagined has some specific features that conferring originally behaviors. The protocol involved is thinking in this application to working in logical mean with the hardware-designed structure. In this sense is performed entire hardware in relation with the signal type generated by the various kinds of sensors. Was be given attention to the adapting electronic signal structures like as an interface between sensors involved, from one the side, and the physical bus system (with all its conflict problems which can appear). The protocol will be considering these features and will be thinking in so manner to increasing the capabilities of the system. The authors contributions are located both electronic hardware part (through the physical line transmitting and the adapter electronic modules) and software part (through the implemented protocol routine system). The electronic hardware part is performing with an 8-bit PCB80C553 Philips microcontroller board. The software part consists in three different routines type: a program to communication with the PC system (involved in the loading procedure), an interfacing program between the microcontroller system and the user, and a protocol communication with the designed bus program. For the PC communication is used the C language and for the user interface and the protocol communication on the bus is used the microcontroller's assembler language. For PC/PCB communication can be used a wireless channel data transfer and so is increased the handling system capabilities.
