Social development to comprehensive information today has entered the
track , information technology is the text , pictures and other tangible
information after processing into computer invisible digital
information , and has unlimited storage, transmission capacity, calling
convenience features , now the main communication line via a cable ,
optical fiber communication lines and radio waves as a means of
information transmission . Since the limited amount of information
transmitted radio waves , and susceptible to interference, can cause
affected the quality of the transmission of information , such as
information distortion , noise and other phenomena occur . Currently
used mainly for the transmission of information communication cables and
fiber-optic communication line transmission line transmission .through bore slip rings
Since
the cable using an earlier communication transmission is a conventional
transmission, technology is more mature , is already facing elimination
communication transmission. Like many developed countries have now
stopped for cable communication transmission line construction , so the
fiber optic communication transmission as the world 's main development
communication transmission. In practical applications often face a
number of rotating parts can usually use a fiber optic rotary joints -
fiber optic slip rings to solve.
fiber optic rotary joint transmission
and cable transmission , fiber due to technical and more mature,
production volume surge , resulting in more and more low cost , and the
cable but because the rising price of copper raw materials and rising
costs . Fiber also information transmission capacity, stability, and
long-distance transmission without loss characteristics. Light optical
fiber transmission is to transmit various information through the
optical fiber transmission. The principle is first converted into
electrical signals of various information , and then modulating the
laser transmitter , a laser beam emitted by the strength of the
electrical signal to reflect the fluctuation frequency , through the
optical fiber conveying the target side , preferably also to restore the
original back to the original information for people to use . As the
laser has a strong directionality and monochromatic characteristics, so
the transfer process itself outside interference and loss is minimal.
Fiber-optic technology is now after 20 years of development , has
experienced multimode shortwave , longwave multimode , singlemode
shortwave three stages , the technology is more and more mature . In
many rotary joint , through the optical slip ring can be solved . It is
because of fiber optical signal is transmitted , so the fiber optic slip
ring connection, you can use non-contact transmission mode , so you can
slip ring state is no wear to work , life will be longer . Can adapt to
a variety of harsh environments, optical fiber transmission distance of
more than 100Km data connection .
Currently, widely used in
fiber optic slip ring robot , remote control systems , military,
aerospace, a variety of equipment , submarine operations , and so a
variety of high-tech , high demand of the facility. As technology
continues to progress , fiber optic slip rings field of play will be more jobs .
