Problems solved by technology

To achieve this kind of timing, the TV must be charged. Once the TV is powered off, the timing cannot be realized.
[0003] And this method of timing can only be set for a period of time, not more than 24 hours, such as setting a timer to start or a timer to shut down, etc., but not a specific date and time timing method, such as timing to a certain year, month, and day.
The user can't see the current real-time time displayed on the TV, which brings inconvenience to the user's use to a certain extent.

Embodiment Construction

[0032] Various preferred embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0033] In the television set with the real-time clock of the present invention, its basic circuit includes a main board, a picture tube, a remote controller, etc., which are common in the prior art, and will not be repeated here. A real-time clock chip is arranged on the TV main board of the present invention, specifically can be set to VC8563, as figure 1 As shown, its circuit module includes: an oscillator unit 110, which is used to generate an oscillating signal at a predetermined frequency, such as the commonly used 32.768KHz, and leads out the two pins 1 and 2 of the chip, namely OSCI and OSCO, as The input and output I / O ports of the oscillator unit can be used to detect and control the oscillator unit. The oscillator unit 110 is connected through a frequency divider unit 120 , sends a clock signal to a storage unit 130 , ...

Abstract

This invention discloses a television and its real time clock realization method, wherein, the television comprises main board with bus set with one real time clock chip, which also comprises the following parts: one oscillator unit to generate oscillator signals according to preset frequency; one memory unit to set time register and to write orderly real time data according to the signals; one logic control unit to control one bus connection mouth and one address register; the said bus interface connects the main board bus and the logic control unit is to control the address register from relative time register to read real time data.

Description

Technical field: [0001] The invention relates to a television set and a method thereof, in particular to a television using a real-time clock chip and a method for realizing the real-time clock thereof. technical background: [0002] The timing function adopted by the current TV is realized by the MCU running software programs. To realize this timing, the TV set must be charged, and the timing cannot be realized once the TV set is powered off. [0003] And this method of timing can only be set for a period of time, not more than 24 hours, such as setting a timer to start or a timer to shut down, etc., but not a specific date and time timing method, such as timing to a certain year, month, and day. . The user can't see the current real time displayed on the TV set, which brings inconvenience to the user to a certain extent. [0004] Therefore, the prior art still needs to be improved and developed. Invention content: [0005] The object of the present invention is to pr...
