| Abstract: | A design method of RS-232/ARINC429 transforming circuit with the form of expand card of computer is discussed. The core of the system is controlling the flow of the data using MCS-51 single chip. Computer exchanges data with MCU through RS-232 interface. Blue print of hardware and flowchart of software of RS-232 as well as ARINC429 interface are given. As a Virtual Bus, the flip--latch is used here to resolve the width matching between MCU and the 429 chip HS3282, actualizing the bus widening of MCS-51single chip. Baud rate of the RS-232 communication is 57. 6Kbps. Rate of ARINC429 is 100Kb/s, and period of which is 50ms. After experiment of more than one year, the circuit is very reliable, which can satisfy the request of communication between computer and aviation equipment. |
