Balance wheel static balance data collecting and processing system and method

Abstract

The invention discloses a balance wheel static balance data collecting and processing system and method, and relates to the technical field of swing wheel static balance data processing. The system comprises a micro vibration sensor, a laser emitting reflecting system, a data collecting fore-end hardware circuit, an analog data collecting card, a switch input and output card and an industrial personal computer, a zero phase-shift bandpass filtering algorithm is complied by using a MATLAB platform loaded in the industrial personal computer to achieve the combination of software and hardware, the advanced zero phase-shift bandpass filtering algorithm is applied so that the filtering function on the signal of a balance wheel static balance system which cannot be achieved by the hardware can be achieved, the hardware is replaced with the software, the filtering cost is greatly reduced, manual maintenance is not needed by a software part, and therefore the system has huge advantage on price; the filtering process depends on a software algorithm, so that filtering precision is not reduced along with the wearing of spare parts, and therefore the product quality is ensured.

Description

Technical field [0001] The invention relates to the technical field of processing balance wheel static balance data, and more specifically relates to a system and method for collecting and processing balance wheel static balance data. Background technique [0002] Watches are very popular in daily life. When people buy watches, they usually take the accuracy of the time as the first requirement, and the average operation of the balance wheel directly affects the accuracy of the time. Therefore, whether the balance wheel is balanced is the key to the accuracy of the watch. If the balance wheel is unbalanced, it needs to be processed to eliminate the partial weight of the balance wheel and achieve static balance of the balance wheel. In this process, it is necessary to collect and process the bias data and the bias angle output by the balance wheel bias sensor. [0003] The current data acquisition and processing of the balance wheel static balance system uses a filter built by har...
