Automated remote terminal and 1553 B bus communication test method

Abstract

The invention discloses an automated remote terminal and 1553 B bus communication test method. The method is suitable for an automated software test method for the command / response type communication with a bus control (BC) of a remote terminal (RT), one-command one-time automatic test, one-command multi-time automatic test and multi-command workflow type automatic test are achieved, the real-time failure monitoring function is achieved, and test, real-time test condition monitoring, test result judgment and management and test report generation are finished at a time. By means of the method, the high-strength repeated test related to 1553 B communication is efficiently achieved beneficially in the space flight and aviation project, the time required by communication test is shortened, test efficiency is improved, the product test process is accelerated, the quality of products is guaranteed accordingly, the product development cycle is shortened, and the method is simple, practicable, efficient and flexible and has good use value for related communication tests.

Description

technical field [0001] The invention relates to an automatic testing method, in particular to an automatic software testing method aimed at the command / response communication between a remote terminal (RT) and a bus control (BC) in a 1553B bus communication network. Background technique [0002] The 1553B bus is a serial master-slave command / response communication data bus, which is often used in aerospace, aviation, and military fields due to its strong anti-interference ability, real-time transmission ability and very high reliability. The scope of application will become wider and wider. Therefore, the testing and maintenance of such electronic equipment is particularly important. Different from ground equipment, aerospace electronic equipment has very high requirements on communication reliability. Once the communication is abnormal during use, the bus control (BC) and remote terminal (RT) will lose contact or lose precious communication data, causing serious losses. A...

Problems solved by technology

[0004] In order to overcome the defects of the prior art, the purpose of the present invention is to provide an efficient, flexible and convenient method for automatic testing of remote terminals (RT) in 1553B bus communication. , The number of instructions is different, the content of communication instructions is different, the communication process is different, and the test intensity is different for testing. It needs its own targeted testing software and manual testing, which is cumbersome and inefficient.
