Generally, it is an optical kinetic energy wave meter, which is simply understood to automatically charge the solar energy and receive the radio waves with signals to automatically adjust the accurate time. What is a wave meter? Through the radio wave receiver and antenna built into the watch, it receives the \"standard time\" radio wave emitted by the transmitter tower, obtains data such as time and calendar, and automatically corrects the time and date of the watch. How are radio signals converted into watch moments?
Standard radio signals are calculated by transmitting waveform signals containing a 'time code' and converted into a time display.
(1) The so-called \"time code\" is composed of \"year, month, day, week, hour, minute, second\" and other time elements, and this signal is then received by the receiver of the watch.
(2) The receiver converts the received signal into the time pulse signal of the watch.
(3) Compare the pulse signal of the watch with the newly received pulse signal to correct the error time, so that the watch will always be accurate. Where do standard time radio waves originate in China? The National Timing Center (NTSC), a subsidiary of the Chinese Academy of Sciences, has built a civil standard time radio transmission tower in Yucheng County, Shangqiu city, Henan province. The signal range covers most parts of China, and remote areas such as Xinjiang and Tibet are temporarily unable to receive it.
Radio signals from the tower can also be heard in the western regions of North Korea, South Korea and Japan. What are the receiving methods of radio wave watches? There are three ways to receive a radio wave watch:
a. Press the button to receive messages forcibly;
b. Automatic regular mail collection;
c. After the battery runs out and stops, the watch will receive the mail automatically after recharging and restarting.
Radio wave watches, also known as Radio Controlled Timepieces. Radio wave watch is a new time product. The purpose is to synchronize and unify the world time. Mainly in order to solve the accuracy of the current quartz watches. Quartz clocks are much more accurate than mechanical clocks, but the day difference is still a second and a half. This error does not have much impact on People's Daily life and the need to correct it, but for military and scientific experiments, it is a big problem to be solved.
The technical principle of the wave meter as a system is: first, the standard time signal is encoded by the standard time timing center (the commercial code is encrypted), and the time signal is broadcast by radio long wave using the low-frequency (20kHz~80kHz) carrier. The radio wave clock receives the low frequency radio time code signal through the built-in miniature radio receiving system, the time code signal is demodulated by the special integrated chip, and then the timing of the clock is automatically adjusted by the control mechanism in the timing device. Through such a technical process, all clocks (or other timing devices) that receive the standard time signal are highly synchronized with the standard time of the standard time center, and then all radio wave clocks display strictly consistent time.
