Abstract
The utility model provides a German electric wave clock which does not need manual timing, and can perform automatic timing according to time electric wave signals sent by a German electric wave tower. The German electric wave clock comprises a German electric wave receiving module, a liquid crystal display circuit for displaying time and date, a press key circuit, a main control chip and an oscillating circuit, wherein the German electric wave receiving module is used for receiving long wave signals sent by a German time service center, processing the signals and finally outputting binary-coded decimal (BCD) codes, and the press key circuit is used for setting time and a bell and starting and shutting down the German electric wave receiving module. The main control chip is used for processing data delivered by the liquid crystal display circuit and the press key circuit and signals received by the German electric wave receiving module, decoding German electric wave signals, restoring the time and correcting time. The oscillating circuit is used for running the main control chip and keeping time. The German electric wave clock is convenient to use and quick and accurate in timing, and does not need setting time manually when power on is performed. The time of the German electric wave clock is exactly the same as the German local time.

Present electronic clock generally all is when relying on the clock internal circuit to control away, in case the clock circuit precision is influenced or battery electric quantity is not enough, time one is long, the shown time of electronic clock will depart from the standard time far away, will show manually after need fixing a breakdown that time adjustment is to the standard time again.This electronic clock needs the user to go after a time to check with the standard time, when doing manually the school, just can guarantee the correctness of shown time, uses not to be very convenient.
The utility model content
The purpose of this utility model provides a kind of when not needing manual school, can be according to the German radio wave clock of German electric wave tower automatic correcting time.
Realize the German radio wave clock of the utility model purpose, comprising:
One German electric wave receives module, is used to receive the long-wave signal of German time service center emission, and this signal is handled, and exports scale-of-two BCD coding at last;
One liquid crystal display circuit is used for demonstration time, date;
One key circuit is used to be provided with the time, quarter-bell, and the described German electric wave of opening and closing receives the accepting state of module;
One main control chip is used to handle data that described liquid crystal display circuit, key circuit transmit and German electric wave and receives module and receive the signal of returning, and solves German electric wave signal, and it is restored the time, and correction time;
One oscillatory circuit is used to move described main control chip and timing.
Described German radio wave clock also comprises a temperature sensing circuit that links to each other with described main control chip, is used for gathering in real time extraneous temperature, and temperature signal is sent to described main control chip, shows in liquid crystal display circuit at last.
Described German radio wave clock also comprises a booster circuit that links to each other with described main control chip, is used for original supply voltage is raise, and thinks that liquid crystal display circuit provides enough voltage.
Described German radio wave clock also comprises a backlight circuit that links to each other with main control chip, is used to the LCDs illumination, makes things convenient for the viewing time at night.
