Abstract

The invention discloses an integrated navigation system tester. The integrated navigation system tester comprises a power controller (1), a data collection switch unit (2), a detection adaptor (3), an automatic tester (4), a main control computer simulator (5) and a test equipment cabinet (6), wherein an integrated navigation finished product is connected to the test equipment cabinet (6) through the detection adaptor (3), the main control computer simulator (5) loads all analog signals needed by testing to the test equipment cabinet (6), the power controller (1) provides power for the whole testing system, the data collection switch unit (2) and the automatic tester (4) are connected with the integrated navigation system through conversion of the adaptor, data are sent to the testing equipment cabinet through communication processing, control signals can be input into an external finished product to be tested, and testing staff can carry out input set on the testing through the testing equipment cabinet. The integrated navigation system tester is reasonable in design, the integrated navigation system installed in a certain type of machine in a factory adopts laser inertial navigation, and a laser gyro has great work mechanism difference from a traditional gyro and is higher in accuracy and reliability. The test method research is product performance testing based on test room conditions, and the check before product installation is achieved.

Description

technical field [0001] The invention belongs to the technical field of aircraft testing, and relates to an integrated navigation system tester. Background technique [0002] The existing integrated navigation system test equipment is mainly applicable to the working mechanism of the traditional gyroscope, which has great differences, insufficient precision, poor reliability, often inaccurate test data, no on-board simulation state, and can not meet the relevant test requirements. The integrated navigation system tester of the present invention has higher simulation signal accuracy, can simultaneously simulate the cross-linking of the on-board system and the finished product of the combined navigation, can complete all performance and function tests of the combined navigation system, and fully meets the laboratory test requirements of the finished product. Contents of the invention [0003] Purpose of the present invention: The integrated navigation system installed in a ce...
