[Abstract]:With the development of avionics technology, bus has become the center of avionics system.

In order to meet the requirements of high real-time, high certainty and high reliability of high speed communication system, 394 bus is a high-speed transmission bus based on 1394b protocol, which will replace 1553 bus as a new generation transmission bus in aviation field. In this paper, the transmission characteristics of 1394 bus are studied as follows: (1) based on the study of 1394b protocol, the development and characteristics of 1394 bus are introduced, and the constraints of transmission characteristics of 1394 bus are discussed and studied. (2) the characteristic of 1394 bus is analyzed and three main parameters which affect the transmission characteristic of 1394 bus are introduced in detail. (3) according to the requirement of 1394 bus for transmission characteristic, the mathematical model of transmission medium is established, and the impedance is deduced. The loss and T-delay parameter model are analyzed experimentally, and the results are consistent with the mathematical model. (4) through the study of the transmission characteristics of the bus, the reliability, impedance matching, In the aspect of loss and delay optimization, this paper puts forward the fault detection, fault isolation, communication sub-card braid connection technology, which realizes impedance matching and delay optimization design, and improves the reliability and real-time performance of 1394 bus signal transmission. Based on the analysis of the transmission characteristics, this paper puts forward an optimal design scheme for the transmission characteristics of the bus, which effectively ensures the high-speed, reliable and stable transmission of the 1394 bus.
