Problems solved by technology

However, the current position measurement device can only achieve data output with a single resolution, that is, one measurement device only corresponds to one measurement resolution.
Therefore, under different measurement conditions, it is necessary to replace different position measurement devices for measurement according to the resolution requirements, which not only increases the measurement cost, but also increases the auxiliary measurement time, which affects the improvement of production efficiency

Abstract

The invention, which belongs to the technical field of measurement, particularly relates to a double-resolution incremental position measuring device. The device comprises a measurement reference unit, a reading unit and a signal processing unit. The measurement reference unit comprises two incremental code channels, and the numbers of scribed lines of the two incremental code channels are in a multiple relation. The reading unit comprises two sensing modules which can be used for respectively reading the position information of the two incremental code channels, converting the position information into corresponding electrical signals and generating two paths of original sine and cosine signals. The signal processing unit processes the electrical signals input by the reading unit and outputs two kinds of position data with different resolutions or standard sine and cosine signals. Position data of high and low resolutions can be generated, the high-speed low-resolution measurement requirement can be met, high-precision high-resolution low-speed measurement can be achieved, and measurement of two different working conditions can be achieved without replacing a measurement device; and the measurement cost is low, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of measurement, in particular to a dual-resolution incremental position measuring device. Background technique [0002] Due to the existence of the signal cut-off frequency, the product of the measurement resolution of the same position measuring device and the maximum movement speed of the mechanical equipment is a fixed value, that is, under the condition of high measurement resolution, the movement speed of the mechanical equipment cannot be too high; High-speed performance, the measurement resolution of the position measuring device cannot be too high. Therefore, in practical applications, it is necessary to comprehensively consider the speed requirements and measurement accuracy requirements of mechanical equipment to determine a reasonable measurement resolution. [0003] Such as CNC machine tools, turntables, etc. will face a variety of working conditions during operation, requiring not only low-spee...
