Spaceflight automation test method based on virtual instrument pseudo instruction mechanism

Abstract

The invention relates to a spaceflight automation test method based on a virtual instrument pseudo instruction mechanism. For an instrument of a certain type, each functional unit of the instrument ispackaged into a pseudo instruction, and for an instrument of a specific model, an ATS system administrator needs to specify a real instruction code corresponding to each pseudo instruction of the instrument type to which the ATS system administrator belongs during addition or management. Based on the mechanism, an upper-layer test service program only needs to specify the type of a required testinstrument and the sending logic of a pseudo instruction, a corresponding real instruction is sent to a user to be edited and reused, and the automation test method can improve the universality of theATS in the aerospace field to the test instrument.

Description

technical field [0001] The invention is oriented to the field of spaceflight, applicable to hardware cascading test software for satellites and other space products, and is an automatic test method based on a general command mechanism of a virtual instrument. Background technique [0002] Product testing in the aerospace field is inseparable from the support of various testing and measuring instruments, so the measurement and control of instruments has become an important basis for Automatic Testing Systems (ATS). The virtual instrument technology that emerged in the early 21st century embeds communication modules that follow specific interface specifications in hardware, uses computer connections and writes corresponding programs to complete the required test work, which improves test efficiency to a certain extent. According to the technical standards of virtual instruments, test instruments in the aerospace field can be divided into two branches: one is to follow the IVI ...

Problems solved by technology

With the ever-increasing demand for aerospace products, its development cycle continues to shorten, and obviously the time left for testing has also been reduced. The above-mentioned "one-type-one-set" ATS has poor versatility, almost zero scalability, and requires immediate development. Frequent consumption of manpower and financial resources has made it difficult to meet the increasing requirements of aerospace testing work. The development of ATS in the aerospace field towards generalization, portability, and easy expansion has become an inevitable trend, and it is also a major challenge so far.
