Electronic clock correcting method based on audio transmission

Abstract

The invention discloses an electronic clock correcting method based on audio transmission. One correcting device transmits information to one or a plurality of corrected devices. The electronic clock correcting method based on audio transmission comprises that (1) the correcting device transmits information and the process comprises the steps of starting clock correction after software start, extracting own clock information and performing audio coding on the information, performing audio coding on starting sign information and ending sign information and attaching the audio-coded starting sign information and ending sign information to the head and the tail of the audio-coded clock information to form audio-coded information to be transmitted, and then transmitting the audio-coded information to be transmitted to a loudspeaker so that the loudspeaker is capable of transmitting the information to the corrected devices in the form of a voice signal, and (2) the corrected devices receive the information through the steps opposite to the steps of transmitting the information, and finally, the extracted clock information is forcibly transmitted to clock chips to change to clock display of the corrected devices, and therefore, electronic clock correction is finished. The electronic clock correcting method based on audio transmission is characterized in that the audio which is easiest to implement and most convenient to operate is used for transmitting the time information to realize quick correction of the electronic clock, and therefore, the efficiency and the operation convenience are improved.

Description

technical field [0001] The invention relates to an electronic clock correction method, in particular to an electronic clock correction method based on audio transmission. Background technique [0002] Electronic clocks are widely used, such as computers, mobile phones, televisions, electronic terminals, automobiles, trains, airplanes and other equipment. Although the accuracy of electronic clocks has been getting higher and higher, the time may still be inaccurate due to power weakening or interruption, human error, software or hardware failure, etc., so electronic clock correction has become an inevitable requirement. At present, electronic clock correction is mainly manual correction, that is, the user uses the electronic clock of a certain device as a reference to manually correct the electronic clock in another device. This method not only wastes time and energy, but also is difficult to quickly Realization, for example, the electronic clocks hanging on the square are b...

Although the accuracy of the electronic clock is getting higher and higher, the time may still be inaccurate due to power weakening or interruption, human error, software or hardware failure, etc., so electronic clock correction has become an inevitable demand

At present, electronic clock correction is mainly manual correction, that is, the user uses the electronic clock of a certain device as a reference to manually correct the electronic clock in another device. This method not only wastes time and energy, but also is difficult to quickly Realization, for example, the electronic clocks hanging on the square are large in size and heavy in weight, and it is very troublesome to correct the time. Some of them need to be removed and corrected because of the difficult installation position, which is more time-consuming and laborious.

[0003] With the wide application of GPS, there are also electronic clock corrections using GPS network. For example, some vehicles, trains and other vehicles can choose GPS time correction, that is, the time is automatically corrected every time the machine is turned on or regularly through the GPS network. This method It is convenient and trouble-free, but it needs the support of GPS network and related electronic equipment, so it is required that the equipment using electronic clock has high application cost and occupies a large installation volume, so it is not convenient to apply on various equipment with electronic clock
