An aerospace vehicle integration performance verification system based on data sharing is divided into a preposition equipment area and a rear end equipment area. The rear end equipment area is divided into a test service area and an operation application area. The preposition equipment area, the test service area and the operation application area are connected through using an optical fiber network. The preposition equipment area is an information interaction link of an aircraft and the rear end equipment area and is formed by subsystem test equipment. The test service area is a core area of the aerospace vehicle integration performance verification system and comprises a test processing server, a data subscription server, a data interpretation server, a database server, a health monitoring and assessment server and a disk array. The operation application area is formed by a control operation platform and a data monitoring terminal. Through using various kinds of services provided by the test service area, functions of remote control/control instruction sending, parameter interpretation and health evaluation rule editing, test flow bookbinding, data display, data query, data playback and test report generation are realized.
