What is the meaning of a light-driven radio-controlled watch?
What is the meaning of a light-powered radio-controlled watch? Many people choose to wear a watch when working or going out. There are many types of watches, including smart ones. Sports watches, phone watches, pocket watches and the most basic electronic watches, etc. So what does a photo-kinetic energy wave watch mean? What is the meaning of photo-kinetic energy radio-controlled watch 1
Introduction to photo-kinetic energy radio-controlled watch
The photo-kinetic energy radio-controlled watch receives the "standard time" sent by the transmitting tower through the built-in radio wave receiver and antenna of the watch. "Radio wave, obtain data such as time and calendar, and automatically correct the time and date of the watch.
The standard time signal uses a high-precision and high-stability cesium atomic clock as the signal source, with an error of one second per 100,000 years, surpassing the old foreign brand watches such as Vacheron Constantin, Premio, Rolex, and Omega. .
Citizen’s radio-controlled watches all use photodynamic energy technology, using any visible light source as energy drive. As long as there is light, there is energy, and as long as the radio waves can be received, there will never be an error. The first photodynamic radio-controlled watch was developed by Citizen in Japan in 1995. There are models with market prices ranging from RMB 2,000 to RMB 5,000. Of course, there are also other brands and names, such as Casio’s solar radio-controlled watch.
Working principle
The standard radio signal is calculated and converted into a time display by transmitting a waveform signal containing a 'time code'. The so-called 'time code' is composed of time elements such as 'year, month, day, week, hour, minute, second'. This signal is then received by the watch's receiver.
The receiver converts the received signal into a time pulse signal for the watch. Compare the watch's pulse signal with the newly received pulse signal to correct the time error so that the watch will always remain accurate.
Signal reception
Press the button to force signal reception
Forced signal reception can be done at any time when the user thinks it is necessary. Manually perform signal reception to correct the time and date of the watch. Depending on the environment, the time it takes to receive the signal will be different. If the signal is strong and stable, the reception time can be completed in about 2 minutes; if the signal is weak and the environment is not good, it will take about 15 minutes.
Automatically timed signal reception;
The automatic timer reception time set by the Citizen Eco-Drive radio-controlled watch is to receive signals at 2 o'clock or 4 o'clock in the morning. During this time, standard radio signals experience less interference. If the message is successfully received at 2 o'clock, it will no longer be received at 4 o'clock; if the message fails to be received at 2 o'clock, it will be automatically received again at 4 o'clock.
After the battery is exhausted and stopped, the watch will automatically receive signals after recharging and restarting.
Can radio-controlled watches purchased in China use signals from foreign transmitting stations? Each signal tower transmits signals at different frequencies. Some of the optical kinetic energy radio-controlled watches sold in the Chinese market can only receive the standard time signal from the radio wave transmitting tower in Shangqiu, Henan.
However, the Citizen Eco-Drive radio-controlled watch, which can automatically adjust the world time, has been sold in foreign markets and is now being introduced to China. This kind of watch can receive multiple stations. You only need to select the city name of the country you are in to get the radio wave signal transmitted by the nearest signal tower and automatically adjust to the local standard time. It is suitable for business people who often travel across countries. What does a photo-kinetic radio-controlled watch mean 2
Introduction to the advantages of a photo-kinetic radio-controlled watch
1. A photo-kinetic radio-controlled watch absorbs light to rotate the hands. On cloudy days It can also absorb energy, but the light source it absorbs is not much. The light provided by the electric lamp can also be absorbed as energy, and there is no need to replace the battery.
2. When the watch is in an environment without light, it will automatically turn on the energy-saving mode, extending the life of the watch. The biggest difference from ordinary batteries is that ordinary quartz batteries will cause great harm to the environment. Pollution, isn't it amazing that a radio-controlled watch can run normally for up to ten years with sufficient power and after turning on the energy-saving mode?
3. Radio-controlled watches use light to charge, so they are environmentally friendly watches that can reflect consumers’ environmental awareness, reduce pollution to the earth, and promote awareness of the protection of nature.
4. Radio-controlled watches generally use the second hand as a warning notification to notify the user. When the battery is low, the second hand will jump for 2 seconds. When the time is inaccurate and needs to be adjusted, the second hand will jump 1.1. This sequence jumps for 2 seconds.
Introduction to the disadvantages of light-driven radio-controlled watches
1. Radio-controlled watches use light sources to charge. Unlike other watches that require battery replacement, in addition to using electricity to maintain normal When the watch is running, excess power will be stored in order to improve the working efficiency of the watch. Generally, after turning on the energy-saving mode, the battery will be exhausted and the watch will stop rotating.
2. After the battery is exhausted, recharge by absorbing the light source, the radio-controlled watch will reset the time and date, but there will still be individual situations, such as the date adjustment is correct, but the end of the month date will still be inaccurate, this It is not a malfunction, it may be because the year and month are not set correctly. At this time, you need to read the manual carefully. What does a photo-kinetic energy radio-controlled watch mean? 3
What is a radio-controlled watch?
The so-called radio-controlled watch is composed of an atomic clock and a radio receiving system, and the accurate time is issued by the National Time Service Center. After being received by the radio receiving system and processed by the CPU to display the time, the error of the radio-controlled watch will not exceed one second in 300,000 years. Simply put, it is a watch that can automatically correct the time after receiving radio waves of standard time information.
Radio timepieces are the fifth generation of timepieces in the development of human timekeeping technology, following hourglasses, sundials, mechanical clocks, and quartz clocks. The emergence of radio-controlled clock technology and products is another revolution in the history of human timekeeping.
Radio-controlled watches, no matter which country they are in, operate on the same technical principle. First of all, there must be a wireless long-wave timing station. The main difference is that the frequencies emitted by timing stations in various countries are different.
What are the characteristics of radio-controlled watches?
1. Accurate travel time. This is unmatched by other watches. The time base collected by the long-wave timing station is an atomic clock, which will not deviate from one second for hundreds of thousands of years. The radio-controlled clock receives the signal it emits, and its hands are synchronized with it (standard time).
2. Ability to semi-automatically correct command errors. In other words, it has an automatic function. As long as the radio clock can receive the timing signal, it will semi-automatically enter the synchronization state. In other words, it can find the current time on its own.
If the clock is lucky enough to have a slight precision error, it can correct itself based on the radio signal emitted by the timing station. Because of this, it doesn't have the "total error" that other clocks have.
3. It can ensure that all radio clocks are at the same time. Because of this, not only can it maintain synchronization with standard time, but there is also no difference between all watches, successfully achieving true time unification.
Therefore, radio-controlled watches are not only a new clock timing technology, it will completely change our traditional way of thinking and living habits. Its industrial application will not be limited to the field of clock timing.
It will definitely be quickly derived into products that can be exposed at any time. Because of this, it can be said that "radio-controlled watches" are a product with great potential and are gaining momentum. However, it has not become popular in our country yet.
If we want to use a radio-controlled watch, it is best to use it in an open place without stumbling blocks. This is because the propagation of radio waves is blocked by terrain and obstacles. This requires us to try to use it where the signal is good.
If a radio-controlled clock cannot receive long-wave radio timing signals, it will be used like an ordinary quartz clock, but it will not be able to synchronize with the standard time and correct errors by itself.
