Detailed Description
Referring to fig. 1, the utility model provides a marine radar intelligence split screen display system, including transceiver, radar main display, signal distributor, a plurality of split displays, signal acquisition card; the transceiver transmits and receives electromagnetic waves and transmits the video echo signal, the bow signal, the azimuth signal and the tuning indication signal to the radar main display; the main display receives the video echo signal, the bow signal, the tuning indication signal and the direction signal, and automatically (or manually) tunes and adjusts the frequency of the video echo signal received by the radar, so that the radar works in a tuning normal state and provides various required power supplies and tuning control signals for the transceiver; the signal acquisition card extracts a video echo signal, a bow signal, an azimuth signal, a tuning indication signal and a trigger signal from a radar main display for controlling each sub-display; the signal distributor performs emission-following amplification processing through the single chip microcomputer, and transmits signals acquired from the radar main display to each sub-display without attenuation; the sub-display stops the operation of the trigger signal in the unit, receives each path of signal sent from the signal distributor, and uniformly uses the trigger signal of the radar main display to reduce the radar measurement error.
A transceiver is adopted to work for a radar main display, then a signal acquisition card is used for extracting trigger signals, bow signals, azimuth signals, video echo signals, tuning indication signals and the like from the radar main display and sending the signals to a signal distributor, the signal distributor sends the signals to other sub-displays without distortion through the processing of a following circuit controlled by an internal single chip microcomputer, and an operator completes the operation or training of the radar by operating various knobs on the radar main display and the sub-displays. A plurality of displays are driven by a transceiver to work, the problem that trainees are inconvenient to practice is solved, the training capacity of a laboratory is improved, the cost is saved, the operation among the displays is not interfered with each other, and the operability is high.
The transceiver mainly provides video echo signals, azimuth signals and bow signals for the display, and the function control of various keys and knobs of the display is generally (except for tuning control signals) to control circuits inside the display, such as: rain and snow suppression, gain control, and the like. In terms of overall structure, the system mainly comprises a signal acquisition card, a signal distributor, various displays and the like.
When the radar scanning device is used, the radar main display and the sub-displays are started, various working power supplies are provided for the transceiver through the radar main display, after the transmitter is preheated, the radar starts to emit electromagnetic waves, and the screen of the radar main display starts to normally display scanning images.
