Embodiment Construction

[0023] Please refer to FIGS. 1-2 at the same time. FIG. 1 shows a flow chart of a method for adjusting the real-time time of an electronic device according to a preferred embodiment of the present invention, and FIG. 2 shows an adjustable The circuit block diagram of the real-time electronic device. First, in step 11 of FIG. 1 , the electronic device records a real-time time RT during the shutdown process as a shutdown time T1 . As shown in FIG. 2, the electronic device is illustrated by taking the electronic device 20 as an example. The electronic device 20 includes a microprocessor 21, a non-volatile memory 22, a sequencer 23, a power source 24, a display 25, An operation interface 26 and a tuner 27, the microprocessor 21 is electrically connected with the non-volatile memory 22, the sequencer 23, the display 25, the operation interface 26 and the tuner 27 respectively. The operation interface 26 is used for the user to input commands, and the display 25 is used for display...

Abstract

The invention discloses a method to adjust actual time of electronic installation, which is characterized by the following: setting the electronic installation as a non-volatile accumulator, a chronogenesis device, a electric source and a microprocessor; exporting a actual time with the chronogenesis device; powering off the electronic installation; adjusting the actual time; recording the actual time with the microprocessor; using as a power off time in the non-volatile accumulator; supplying electric energy to the chronogenesis device with the electric source when power off and unexhausted electric energy; refreshing the actual time with the chronogenesis device continuously; making the actual time later than the power off time; controlling the chronogenesis device with the microprocessor; setting the actual time to a predetermined time when the electronic device powder off and exhaust the electric energy; making the power off time later than the predetermined time; setting the electronic installation in the course of open; comparing the actual time and power off time.

Description

technical field [0001] The present invention relates to an electronic device and a method for adjusting real time, in particular to an electronic device which can determine whether to update the real time according to the shutdown time and the real time when starting up and the method for adjusting the real time. Background technique [0002] When using a consumer electronic product that includes a video signal processing device, such as a DVD recorder, most users need to manually input the system time. Or some machines can refer to some time information hidden in the TV signal sent by the local TV system to achieve the function of setting the time. Once the time is set, it can be counted normally and accurately by means of electric energy. That is to say, adding a battery allows the machine to continue the action of the real time counter (RTC) even when the machine is powered off. [0003] However, once the system is powered off and the built-in battery provides effective...
