1553B bus network integration test method

Abstract

The invention discloses a 1553B bus network integration test method. The method comprises the steps: 1, carrying out preparation and offline, performing designing according to a bus network, accurately making a physical board model, placing all components according to actual requirements, enabling cables to be offline according to model requirements, enabling the trend of wiring harnesses to meetdesign requirements, and enabling an overlong whole section of cables to be allowed to be coiled; 2, identifying an end code, a bus code, a sub-line code and the like in the wire harness, so as to enable a bus network to be easy to perform feature identification in an installed environment or other environments; 3, assembling a connector in the bus network, wherein the connector comprises a sub-line connector and a 38999-series No.8 connector; 4, carrying out butt joint on the parts, needing to be switched over, of the buses and the parts, needing to be extended, of the sub-wires through wireconnectors, and mainly involving the crimping technology and the thermal shrinkage technology; and 5, testing the bus network subjected to the steps, and performing large-data-volume analog signal receiving and transmitting verification on the bus network from static and dynamic aspects by adopting a comprehensive network tester.

Description

technical field [0001] The invention relates to a test method, in particular to a 553B bus network integration test method. Background technique [0002] The 1553B data bus is the abbreviation of the MIL-STD-1553B bus. It is a time-division command / response multiplex data bus inside the aircraft. It has developed into an internationally recognized data bus standard and is widely used in aviation systems, ground vehicle systems, and ships. System and other military platforms, with more than 20 years of military application background in foreign countries. At present, my country's military is in the stage of development from mechanization to informatization. New fighter jets have been fully equipped with GJB289A (MIL-STD-1553B) data bus, and are gradually adopted in aviation, warships, aerospace and other fields. [0003] The 1553B data bus cable network is a bridge to realize the connection between the bus controller and the remote terminal in the bus system, and has a wide ...

Problems solved by technology

[0005] In addition, how to comprehensively and effectively test the 1553B bus network has been an important topic for a long time. The detection of the bus network is not only the detection of on-off performance and insulation, but also the means, methods and items of data bus network testing in different factories. It is not uniform, and more is based on the successful experience of the project to carry out targeted testing and acceptance of the data bus network. Because of this, most of the current bus networks are mostly completed by the aircraft assembly workshop
