The Transceiver For The ГOCT18977 Data Based On HS3282

The testing instrumentation of aircrafts is critical equipment to ensure the safety of aircraft flight. Therefore, the reliability of these testing instruments is the basic of safety of flight.This paper has developed a device for the detection of Russian aircraft instrumentats. The device used by the U.S. protocol chip HS3282 achieves the transceiver of theГОСТ18977 bus data and complete the detection of the instruments. The specific project of the design is as follows: a DSP used as the core component of a data processing and transmission; a HS3282 used to achieve the transceiver ofГОСТ18977 bus data; a USB2.0 chip used to connect the lower computer to the host computer fast and conveniently; a CPLD used for the external control circuit to improve the integration and stability of the system; UsingVC+ + to program ther user interface so that users operate easily and expediently.In this paper, theГОСТ18977 protocol and ARINC429 protocol are firstly introduced, and according to the comparison, it is illustrated that the HS3282 can be used to realize the detection of the Russian aircraft instruments. Then, the system principle is introduced, and the design and implementation of specific hardware circuit as well as the software design are described. Lastly, the debug program and the design summary are introduced, and some proposals for future development work are put forward.
