Description

technical field [0001] The invention belongs to the technical field of level meter measurement, and in particular relates to a level i-angle detection device and a detection method. Background technique [0002] A level is an instrument used to measure the level difference between two points in space. During the test, since the collimating axis of the telescope of the level cannot be kept completely horizontal, there will always be a small angle with the horizontal plane, which is called the i-angle of the level. When the i angle is zero, no measurement error will be caused, but usually none of the i angles is zero, which will cause a measurement error, and the larger the i angle, the greater the resulting error. Therefore, before measuring, it is necessary to adjust the i angle of the level to make it within the allowable range of error. There are many ways to measure the i angle, but the traditional measurement method has the following problems: the measurement method is...

AI Technical Summary

Problems solved by technology

There are many ways to measure the i angle, but the traditional measurement method has the following problems: the measurement method is complicated, the calculation process of the i angle is complicated, and the efficiency is low, which leads to a waste of time for the adjustment of the i angle in the early stage; because the i angle will be affected by the external environment Due to the influence of temperature, humidity and vibration, etc., it is necessary to perform i-angle calibration every once in a while or even before each use of the level. The traditional i-angle measurement method is no longer suitable for quick calibration.
