Description

Technical Field

[0001] The invention relates to a polymerized angle measuring circuit comparison test system. Background Art

[0002] In the actual working process of high-precision rotary equipment, since the angle measuring devices used are varied and the accuracy cannot be tested in real time, complex detection devices such as optical detection instruments are required. However, in the angle measuring system working in mass production and special conditions, the angle measurement test time is long, the accuracy control cannot be unified, and it is easy to introduce more human errors. At the same time, the angle measurement system test circuit and peripheral equipment are mostly customized, which puts higher requirements on design cost and reliability. The existing rotary equipment test devices are mostly temporary test environments. This test method can meet the needs of individual tests, but it cannot meet the needs of the changing angle measuring device types and test environments. In particular, it cannot achieve efficient testing for batch testing requirements, and its accuracy cannot be guaranteed. There are also combined angle measurement test systems, but their complex signal access systems cause certain interference to the design and actual testing, and there is no corresponding comparison feedback processing mechanism, so online calibration cannot be performed.
