| In this paper the process to design the Computer Aided桾esting system for WP? aeroengine test run is discussed. First, the whole programing and human梒omputer interface design is addressed by using the theory of system engineering. Then the principle to select the hardware ~. the configuration of the system primary arithmetic and the digital filter used in the software system are discussed in detail. In the last, the means to improve the system reliability are presented. This system has been used for WP? aeroengine test run in XIæ‰N AEROENGINE (GROUP) LTD. |
