Embodiment Construction

[0021] The invention introduces an endpoint detection algorithm and performance calculation of a double tourbillon watch.

[0022] figure 1 It is a schematic diagram of the watch signal cycle of the present invention; figure 2 It is a schematic diagram of the detection result of the sound signal endpoint of the single escapement speed regulating mechanism in the embodiment of the present invention.

[0023] Such as figure 1 and figure 2 As shown, 1. Endpoint detection algorithm, since the sound signal of the mechanical watch is generated by the collision of the escapement speed regulating mechanism, it is a periodic signal. Each cycle of a mechanical watch signal has three peaks. By measuring the time difference between the first peaks of each period, we can compare the period of the sound signal of the mechanical watch under test with the standard period, thereby calculating the daily difference of the mechanical watch and measuring the polarization of the escapement ...

Abstract

The invention discloses a double-escapement-regulator mechanical watch test method, comprising the following steps of: signal acquisition and signal analysis, wherein, the signal analysis includes initial watch-sound signal input and pretreatment S1; watch sound separation and analysis S2; automatic parameter adjustment S3; watch-sound signal input and pretreatment S4; watch sound separation and analysis S2; parameter computation S5; and screen display. The test method of the invention has the advantages that as watch-sound signals are effectively separated and the watch sound can be analyzedand displayed on a screen, the performance test of escapement-regulation mechanical watches can be realized, and the method of the invention has high precision, stable and reliable service and convenient use.

Description

technical field [0001] The invention relates to a watch calibration instrument; in particular, it relates to a mechanical watch calibration device and a detection method with a double escapement speed regulating mechanism. Background technique [0002] Every mechanical watch will emit a unique sound. The "tick" sound of a mechanical watch comes from the collision in the escapement governor. The escapement governor is a feedback regulator that determines the timing accuracy of the mechanical watch. The mechanical watch calibrator is an instrument that uses the sound signal of the escapement speed regulating mechanism to detect the performance parameters of the mechanical watch. At present, all mechanical watch calibration instruments are designed for mechanical watches with a single escapement speed regulating mechanism. However, the double tourbillon watch that has become popular in recent years, a typical mechanical watch with double escapement speed regulating mechanism,...
