Timekeeper and time feedback, time calibration and pointer positioning method

Abstract

The invention relates to a timekeeper and a time feedback, time calibration and pointer positioning method. The timekeeper at least comprises a hour wheel sheet, a minute wheel sheet, an electric motor and a controller, wherein the minute wheel sheet is provided with a light hole, and the upside and the downside of the light hole of the minute wheel sheet are respectively provided with an infrared optical coupling generating side and an infrared optical coupling receiving side; the infrared optical coupling receiving side generates a position feedback signal and sends to the controller when receiving infrared light; and when receiving the position feedback signal, the controller obtains the current-time minute number of the timekeeper, and determines the current indication time of the timekeeper by cooperating with an hour counter, wherein the current-time minute number of the timekeeper is a minute number preset by a software. An infrared optical coupling apparatus disclosed by the invention is capable of generating the position feedback signal and sending to the controller when the light hole passes the exact downside of the apparatus, so that the current time of the timekeeper is determined, the effective time feedback and reliable transmission of pointer position are realized, and further calibration of the timekeeper is realized, and through assistant intelligent positioning of a pointer by a software, convenient pointer installation positioning is realized.

Description

technical field

[0001] The invention relates to the technical field of timing control, more specifically, to a clock and its time feedback, time calibration and pointer positioning methods. Background technique

[0002] Most of the existing clocks and watches do not have pointer position recognition and feedback systems, and the clock travel time system works in an open-loop state; only a few architectural clock products are designed with feedback mechanisms, but the existing architectural clock feedback mechanisms are not advanced enough due to technology. It is not mature enough, so there are many problems in the reliability of the structure, the stability of the feedback signal, the operability of installation and maintenance, etc., which directly affect the reliability of the entire control system and the quality of architectural clock products. Therefore, the research on pointer position feedback technology with simple and reliable structure, advanced technical methods,...
