radiocontrolledtimepieces skills as a system principle is: First, by the scale time scale Time Service Center will be encoded time signal (commercial code is encrypted), the application frequency (20khz ~ 80khz) method of the time the carrier signal sent by radio broadcast to the long wave. Watch through the built-in micro-wave radio receiving system to receive the low frequency radio time code signal, when the specific integrated chip code signal demodulation, then dominated by a timing device inside the body automatically adjust the clock timing. Skills through such a process, so that all scales of time to receive the clock signal (or other timing device) with the scale time scale Time Service Center, adhere to a high degree of synchronization of time, then all the radio shows stringent consistent time clocks.
The working principle of electronic watches and clocks are based on "Electro-magnetic, magnetic raw power," designed by the physical phenomena. That the energy is converted to magnetic energy, then the magnetic energy is converted to mechanical energy to drive pin hours of operation, to achieve timing purposes.
1, transistors balance sheet family favorite --- the country's leading watch web watch forums watch forum watch watch watch network media forum.
The batteries for energy, using transistors as switches, balance spring for the oscillation system, a unified movement for the j1 type, shape and ordinary alarm clock.
2, crystal clock
Clock balance wheel with the same transistor performance, coupled with an alarm when the power supply device.
3, transistors pendulum clock
Dominated by electronic circuit components placed as an oscillation, similar to the shape and mechanical pendulum clock. Watch Brand 2 n3 s # q7 B, {S
4, quartz
With "crystal" as the oscillator frequency to the electronic control motor operation, driven pointer. High precision of travel time. Varieties of table clock, wall clock, calendar clock, alarm clock, music clock, floor clock, is also a car bell, ships bell, astronomical clock, and other skills to use clock.
5, digital clock
Also used as a quartz crystal oscillator, the direct use of LED or LCD display time, no mechanical transmission. With hours, minutes, seconds, calendar, weekly calendar, calendar and other features.
6, electronic watches family love the table
Replace the battery as the energy winding, not the hands of strings, a variety of structures, shape with the mechanical watch, collectively referred to as electronic watches, according to the invention has the form and structure, electronic form is divided into four generations.
The first generation electronic watch balance spring, balance spring as the oscillator is to micro batteries for energy, balance wheel driven by electronic circuits work.
The second generation of electronic tuning fork watch, as is the metal tuning fork oscillator, electronic circuit output pulse current, so that the mechanical tuning fork vibration.
The third generation Analog quartz electronic watch, is the application of quartz resonators as oscillator after divider driven by electronic stepper motor driven gear and pointer.
Is a digital quartz electronic watches, it is also used as a quartz crystal oscillator, the difference is that after a divider, after counting and decoding applications in digital form display to show time.
First three generations of electronic watches are mechanical pointer with traditional institutions, while the use of large-scale integrated circuits, completely out of the traditional mechanical structure of the fully electronic watch.
Different types, principle different, but always changing it.

Electric watches employ a very small electric cell of approximately 1.35 volts. This energy is switched into a coil of wire (electromagnet) that is mounted on a balance wheel. The balance wheel then drives the hands in exactly the reverse manner of a mainspring-driven watch. In 1957 the electric watch was introduced in the United States.
One electric watch uses a tuning fork that drives a ratchet wheel, which in turn drives the hands. It does not use a switch, but a transistor to connect the power to its coils. This combination results in a very accurate timepiece. It does not tick, but hums. The second hand does not move in jumps as is true in most watches, but moves smoothly like a second hand of an electric clock. This watch was introduced in 1961. Self winding watches have a swinging weight geared to the mainspring. As the wearer moves his arm, the weight is swung and the mainspring is wound
