Embodiment Construction

[0020] A back sheet that meets the electrical characteristics of ArInc659 bus includes four sets of complete combination circuits, each set of combination circuits contains a voltage conversion circuit and an impedance matching circuit. The computer 5V power supply connection voltage conversion circuit, the converted 2.1V is again connected from the left and right ends of the backplane from the left and right ends, respectively. See figure 1 .

[0021] The voltage conversion circuit includes a triplet regulator N1, a first filter capacitor C1, a second filter capacitor C2, an energy storage capacitor C3, and a resistor R1, R2. The computer 5V power supply is divided into two channels after the fuse f1, and the input end of the triple-terminal regulator N1 is connected, and the first filter capacitor C1 is connected, and the other end is connected to DGND. The adjustment end of the three-terminal regulator N1 is divided into two channels, one terminal, one terminal, one terminal, ...

Abstract

The invention provides a backplane based on a three-terminal voltage regulator, a precision resistor and printed board design. The backplane includes a voltage conversion circuit and an impedance matching circuit, is mainly used in implementation of the bus backplane which conforms to an ARINC659 bus protocol of an onboard computer, and can meet characteristics such as electrical isolation, levelstability, impedance matching and the like required by the ARINC659 bus protocol.

Description

Technical field [0001] The present invention belongs to the field of airborne computer bus communication technology, and the bus back panel that meets the electric character requirements of the ARINC659 bus protocol. Background technique [0002] With the development of domestic army civil aircraft, the electronic system of the aircraft gradually entered the full information fusion era, requiring a bus to realize fast and reliable communication between the internal modules of the airborne computer. As a high reliability fault-to-line serial bus, the ArInc659 bus is increasingly widely used. The bus backplane required by the ArINC659 protocol meets a variety of electrical properties. [0003] However, the electrical design information of the ArinC659 bus backplane has not been seen in China, which has not been detailed in detail due to technical blockade. [0004] In order to implement the ARINC659 bus protocol, the present invention proposes a backing plate based on three-end reg...
