Abstract
The utility model discloses a marine navigation radar echo signal sharing network mechanism, which comprises a transceiver device, a signal processing device, a router, an Ethernet bus and a plurality of radar terminals. A radar transceiver outputs a radar echo signal. The signal processing device is connected with the radar transceiver, and converts an analogue signal output by the radar transceiver into a differential digital signal. The router is connected with the signal processing device, and accesses the Ethernet bus. The radar terminals are distributed in parallel, and are connected to a computer network through the Ethernet bus to obtain the digital radar signal obtained by the conversion of the signal processing device from the signal processing device respectively. Only one of the accessing radar terminals can transmit a signal to the transceiver device, and the other radar terminals only can have a radar image display function, namely the other radar terminals only can display devices. Radar echo information can be fully used and shared.
Description
Technical field
The utility model relates to collection, conversion and the transmission technology of radar signal.
Background technology
Marine navigation radar is the radar that ensures ship's navigation, also claims marine radar.It is specially adapted to night, greasy weather guiding ship discrepancy bay, passes through ditch and cabotage, mainly plays the crashproof effect of navigation.
The equipment radar starts from during the World War II on the ship, expands civilian merchant ship after the war gradually to.International Maritime Organization (IMO) (IMO) regulation, the above ship of 1600 tonnages must the equipment navar.A vital task of navar is that target is marked and drawed, and this task changes by robot radar plotting device just gradually to be served as.International Maritime Organization (IMO) stipulates that also the above ship of all 10,000 tonnages progressively installs this device.
General radar is illustrated in the center of plane position indicator (PPI) (seeing radarscope) to self as fixed point.But in navigation, boats and ships are always done relative motion with fixed target or moving target from motion.The radar that adapts to maritime environment should be the radar of real motion, must be able to import the speed of a ship or plane and the course of boats and ships self automatically, and data must be quite accurate.
After the World War II, the basic structure of microwave marine radar does not have very big change, and the principle of work of magnetron transmitter, high sensitive receiver, diplexer, antenna and display is all with former identical, but Performance And Reliability is improved.Application solid-state electronic technology is greatly improved the reliability of equipment.The modern navigation radar is except that magnetron with the cathode-ray tube (CRT), and other active circuit elements all use transistor and integrated circuit basically.Because circuit improves, pulse width reduces to 0.1 microsecond from 1～2 microsecond, and the magnetron peak power is brought up to 50 kilowatts from 3 kilowatts, thereby target discrimination and sensitivity are improved.The leaky wave antenna array makes antenna beamwidth reduce to 0.7 ° or 0.8 ° from 2 °, and the target azimuth resolving ability is improved.Because these improvement can be depicted course line formula image on 40 centimetres of plane position indicator (PPI)s, be convenient to boats and ships and when along the coastline navigation and entering and leaving port, mark and draw.The later stage sixties; Utilize small-size computer to succeed in developing robot radar target following and estimating system; It can handle radar video voltage, and the detection and tracking target is measured the relative motion between boats and ships and the target; Motion and closest approach that scheduled target is following assist human pilot to take to avoid action.It is the visual plant in the navigation field that navar and robot radar are marked and drawed device, is the necessaries that makes a land, guides boats and ships discrepancy harbour and ditch.
As modern marine vessel, extremely important to the abundant use of radar return information.
Summary of the invention
The purpose of the utility model is to provide a kind of marine navigation radar echoed signal shared network mechanism, can realize the abundant use to radar return information, information sharing.
The utility model realizes through following technical scheme, and whole radar signal shared network mechanism comprises transceiver device, signal processing apparatus, router, industry ethernet and some radar terminals,
Said transceiver device comprises interconnective radar antenna and radar transceiver, radar transceiver output radar echo signal,
Said signal processing apparatus is connected with radar transceiver, and the analog signal conversion that radar transceiver is exported becomes differential digital signal,
Said router is connected with signal processing apparatus, router access network based on ethernet bus,
Said some radar terminals each other and column distribution connect through industry ethernet separately and go up in the computer network to realize the obtaining digital radar signal from signal processing apparatus conversion back output respectively.
Through the radar signal of signal processing means processes, through router, share in the computer network, realize that a radar transmit-receive machine is connected with many radar terminals, radar terminal is signal Processing terminal and display device.The radar terminal that inserts has only one can send signal to transceiver device, and other radar terminals can only play the function that shows radar image, promptly is display device.
The utility model marine navigation radar echoed signal shared network mechanism; Anti-interference is good, stable performance; Can share these digital signals according to procotol then converting analog voltage signal to differential digital signal through signal processing apparatus in the set of signals such as the video of radar transceiver, control.A radar transceiver can be connected with many radar terminal displays, makes display image share to greatest extent, brings convenience to navigation.Realize sharing of radar echo signal and use thereby the original analog of radar is carried out after the analog to digital conversion access network based on ethernet, with the modernization of ship reconstruction trend.
