Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] like figure 1 As shown, the workstation includes a signal conditioning circuit card, data acquisition card, data communication card, 2 sets of special cables, a set of RS-422 cables, data analysis module and data display module (software). Insert the signal conditioning circuit card, data acquisition card and data communication card into the PCI slot of the workstation. The signal conditioning circuit card uses a 50-core special cable to connect with the gyroscope under test. The signal conditioning circuit card uses a 37-core special cable to connect with the gyro. The data acquisition card is connected, and the data communication card is connected with the tested gyroscope using RS-422 communication cable. The signal conditioning circuit card is specially designed for the present invention.

The invention discloses a system for comprehensive testing of the performance of a gyro combination. The system comprises a data communication card placed in a work station, a data analysis module and a data display module, wherein the data analysis module is used for generating a data request command at fixed time according to testing requirements, sending the data request command to a to-be-tested gyro combination via the data communication card, analyzing a first data signal fed back by the to-be-tested gyro combination and received by the data communication card and calculating each performance index, and the data display module is used for displaying the value of each performance index calculated by the data analysis module. The invention also discloses a testing method used by the system for comprehensive testing of the performance of the gyro combination. The system and method provided by the invention can realize comprehensive testing of the performance of the gyro combination and visually present performance indexes related to stability and accuracy of gyros. The invention has the beneficial effect that the system and method more accurately acquire operational data of gyros, perfect the contents of testing of the gyro combination and improve work efficiency in testing and examination of gyros.
Description
technical field [0001] The invention relates to a technology for testing the combined performance of a gyroscope, in particular to a test method for comprehensively testing various properties of a gyroscope. Background technique [0002] Modern gyro combination is an instrument that can accurately determine the orientation of moving objects. It is an inertial navigation instrument widely used in modern aviation, navigation, aerospace and national defense industries. Its development is of great importance to a country's industry, national defense and other The development of high technology has very important strategic significance. With the continuous update of gyroscope combination technology, its test indicators are more diverse and its statistical calculations are more complex. Therefore, a method is needed that can test various performance indicators of gyroscopes more comprehensively, quickly and accurately. [0003] In the prior art, there is no comprehensive and syst...
