Electronic clock capable of detecting working status and detection and calibration method

Abstract

The present invention discloses an electronic clock capable of detecting a working status. The electronic clock comprises a display state detecting circuit for determining a real time of a clock, a wireless communication circuit I which is connected to a computer of a server end via a network and is used for uploading the working status of the clock and receiving an accurate time, a power detection circuit which is connected to a single-chip microcomputer I, and measures electronic clock battery power and output current, the single-chip microcomputer I which coordinates the working of variousparts and is used for the synchronization of a clock circuit I, and the clock circuit I which is internally provided with a temperature measuring device, a fine-tuning capacitor and a rotation knob. At the same time, the invention also provides a clock detection and error calibration method. The invention provides the electronic clock capable of detecting a working status, the real-time detectionof whether working is normal or not and whether power is sufficient is realized, at the same time, an occasional error and a system error can be automatically calibrated.

Description

technical field [0001] The invention relates to the technical field of electronic clocks, in particular to an electronic clock capable of detecting working states. Background technique [0002] The clock is an indispensable time indicating tool in many important places, especially in today's society where every second counts, people have higher and higher requirements for the accuracy of time, and clocks and watches with unified time are needed in some public places or important places, such as In important national examinations such as college entrance examinations and civil service examinations, in important places such as airports and railway stations, and in activities such as New Year's Eve and countdown, more accurate time is required. [0003] Quartz electronic clocks use batteries as energy sources, quartz oscillators as time references, and integrated circuits as the core to display the structure of time through pointers or numbers. Among them, the needle quartz wa...

AI Technical Summary

Problems solved by technology

[0004] Traditional electronic clocks can have functions such as time display, time calibration, and early warning, but they cannot detect in time whether the quartz clock hands are moving or not, whether they are correct or not, and whether the power is sufficient or not, and can only perform simple time calibration without distinguishing Whether the time error is caused by accidental error or systematic error, it cannot be calibrated fundamentally
