China became the fifth country radio clock technology

Mechanical watch every day normal "jet lag" 20 seconds, quartz of "jet lag" of about 1 second, no less able to radio clock. Yesterday, China has independently developed the first commercial radio clock in the Shanghai market. After Germany, Japan and the United States, the country became the first five has the "watch the most" technology.

Automatic correction of natural errors

Radio clocks are quartz clock in the younger generation, some of the performance but excel the predecessors. It is built-in antenna, decoder chips, data processing CPU and automatic correction system, by identifying the ground long-wave radio signal tower at any time to determine the time, automatic error correction of the natural time clock. At the same time, it also capable of "companion" in unison, that the realization of all radio clock shows the same time.

Own intellectual property rights

80s of last century, the world's first clock radio commercial use only born in Germany and then sold in Europe. In Japan, the radio clock become synonymous with high-tech watches, with 40% market share. This summer, Japan also began icing on the cake table radio - combined with optical kinetic energy, power saving and other new concepts, to seize the Chinese market.

3 years ago, the project by the National Institute of watches, fine branches of domestic commercial radio group chaired table technology project started. In 2006, the high 249 meters of the radio transmitter settled Shangqiu bell, signaling a radius of 2000 kilometers, covering China, and radiation Korea, North Korea and parts of Japan. Today, China's own intellectual property clock radio success came, breaking the monopoly of the developed technology for commercial radio clocks.

Precise "targeting" Beijing

Domestic radio clock square head side brain, similar to the appearance and quartz, but swept away the old clock fast or slow non-abuse, no manual calibration, precise "targeting" Beijing Time. Beijing is China's standard time, from an error of only 1 second 30 years of atomic clock timekeeping, National Time Service Center by the Chinese Academy of Sciences released. Clock radio long wave radio signals are subject to the guidelines, and standard atomic clock time "single" connection, naturally exactly right.

Project Leader, Chairman of the Golden Section Changzhou fine to point out that the Chinese auto school day when the clock radio 7, and innovative display of wireless signal receiving state, free from the watches are not allowed to go on when there are deviations "time trouble." If subjected to electromagnetic interference and radio reception there blind spot, radio clock can also be used as a normal quartz clock.

Meet the needs of different areas

Next, domestic radio clock will further lower "value" (currently 300 yuan per clock radio), transformation functions, update the style to meet the bank securities, public transportation and other needs of professionals in different fields. Especially the new and unique global wave form, will "aerialists" bring the world trip without the time difference: the aircraft had just landed, the global wave form automatically recognize local time zone, the command dial on the hours, minutes, seconds their places.
