A Testing and Verification Method for Remote Terminal Acquisition System
The paper introduces a remote terminal acquisition system which includes two remote terminal acqui-sition units and two remote interface units,and proposes a testing and verification method for the acquisition sys-tem.It simulates the upper computer of the flight control system and the interconnected excitation signal sources;a-chieves data exchange and completes testing verification experiments based on test cases.The test design and im-plementation mainly includes the remote terminal acquisition system through 1394B bus networking test,a single remote terminal acquisition unit or a single remote interface unit through 1394B bus networking test.This testing and verification method achieves functions such as simulation,record display,and data analysis of remote terminal collection system cross-linked data.The results of the test and verification test show that through this test verifica-tion method,comprehensive verification of the function and performance of the remote terminal acquisition system has been achieved,and fault injection testing of the remote terminal acquisition system has been achieved,effec-tively improving the testability and reliability of the remote terminal acquisition system.
