Abstract


Remote terminal ( RT ) is an important part of the advanced aircraft electrical system , is one of the key component to achieve of aviation electrical control system . Its main task is the main exchange , the main DC bus bar and electromechanical power controller (EMPC) to monitor and control the quality of the external power supply monitor . This paper mainly discusses the research and design of the remote terminal . RT real-time , fault tolerance, and reliability requirements to meet the power supply system , RT PC104 module as the core processor with Intel 82C55 I / O expansion , the software on the introduction of embedded real-time multitasking operating system VxWorks software platform. Hardware design, RT into the power supply module , analog modules and digital input and output modules , and detailed design of the chassis and the various modules ; MIL - STD -1553B bus design bus communication , to solve the load real-time monitoring , the busbar state detection , Bus Transfer contactors and other controls as well as with the PSP data communication . Software design 1553B bus , AD and DIO -driven development ; divided based on the inherent requirements of the functional requirements of RT and VxWorks , application tasks and assign the task priority ; using the C programming language, the function of each task module . Services provided by the operating system to manage the various application tasks , improve system reliability and real-time . In addition, this paper also discusses the design of RT -in self test ( BIT ) .
