[Abstract]:With the development of the research on a certain type of aircraft circuit board, the number of communication circuit boards containing TS80C186EB20 embedded microprocessor is increasing day by day, so it is necessary to carry out systematic research on this kind of circuit boards. At the same time, in order to improve the deep repair ability of this type of multifunctional bus communication circuit board, the hardware design and software development technology of 80C186 processor system need to be deeply studied from the forward angle. Firstly, an experimental board based on 80C186XL is developed. The working mode of the processor, the design of the minimum system hardware circuit, the development of software programming and the solidification of the program code are studied. Based on the analysis of multifunction bus communication circuit board, a simulation board based on enhanced TS80C186EB20 is developed. This research is of great significance for mastering the application technology of TS80C186EB20 bus communication circuit board, so this thesis has strong pertinence and high application value.

The hardware characteristics of 80C186 and the method of using the software development environment of ARINC-429 / RS-422 / RS-422 / Emu8086 have been studied systematically, and the minimum system of 8255Ac / 8253A / 8251A / ARINC-429 / RS-422 / RS-4858086 has been studied systematically. In order to lay a foundation for the hardware design and software development of the experiment board based on 80C186XL and the imitation board based on TS80C186EB20, taking 80C186XL as the processor, a timer with internal processor is developed. The parallel port input / output 8255A, timing / counter 8253and serial port communication 8251A are used as the experimental board, a kind of imitation board .3with ARINC-429 bus and RS-232 RS-485N RS-422 serial communication bus is developed, which is based on Emu8086 and ISE13.1 software. Write the program of experiment board and imitation board. The test board consists of 80C186XL initialization and 8255An 8253K8251A program code, and the imitation board includes TS80C186EB20TL16C754B initialization and ARINC-429RS-232RS-485RS-422 bus communication program code and XC95144 coprocessor software code .4. the exe format file is analyzed and the operation rules of 80C186 series processors are analyzed. The process of converting EXE format file to BIN-HEX format file is given. Based on Visual C 6.0 development environment, an EXE format file conversion software. 5, which is suitable for 80C186XL and TS80C186EB20, is developed, and the industrial computer is used to convert the EXE format file to the BIN-HEX format file. An experimental verification system is set up for multi-function signal circuit board, such as RS-485 to RS-232 converter TLC485N RS-422 to RS-232 converter UT-202 and computer serial port debugging assistant software. The function modules of the test board, such as 8255An 8253N8251A and ARINC-429 RS-232RS-422RS-485, are tested and verified. Through the research of this subject, not only can we master the working principle, hardware design and software development of 80C186 processor, but also the hardware design and software development method can be applied to all kinds of 80C186 test systems.
