Description
Technical field
The present invention relates to a kind of antenna assembly, relate in particular to a kind of antenna assembly and signal acquisition method thereof of air defence warning, for antiaircraft technical field.
Background technology
Air defence warning is the alarm of reporting enemy's air strike.In wartime, undertaking and guiding the masses to evacuate smoothly the task of reporting of action prevention air strike; At ordinary times, hold concurrently negative flood control, shockproof etc. withstanding natural calamities and the task of promptly reporting of secondary disaster people's air defense.Along with the process of Chinese Urbanization is accelerated, increasing population enters cities and towns, and the menace of wars that the international situation of facing changeable situation causes and frequently disaster, how timely, effectively early warning, be the cardinal task that is related to broad masses of the people's security of the lives and property.
In wartime situation, the battlefield survival of air defence warning facility is most important, and antenna, as giving away one's position, requires away from alarm terminal, even if antenna is destroyed, main frame viability is strong; But Principle of Antenna alarm terminal will be very high to the requirement of feeder line, must design a kind of communication means, make the feeder line of antenna short, communication efficiency is good; Such antenna system, has great importance for the quick-reaction capability (QRC) and sensitivity, the reliability that improve people's air defence.
Summary of the invention
The present invention solves the deficiencies in the prior art, and a kind of compact conformation is provided, and has improved antenna assembly and the signal acquisition method thereof of the battlefield survival of air defence warning main frame and a kind of air defence warning of reliability.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of antenna assembly of air defence warning, comprise main frame and signal transmitting and receiving module, in described main frame and signal transmitting and receiving module, be respectively equipped with remote serial port, between described remote serial port, by optical fiber, be connected, the top of described signal transmitting and receiving module is provided with antenna, and described antenna is connected by feeder line with signal transmitting and receiving intermodule.
Antenna, away from the main frame of air defence warning, has improved battlefield survival and the reliability of air defence warning main frame; The short communication efficiency of feeder line is good; Such antenna system, has great importance for the quick-reaction capability (QRC) and sensitivity, the reliability that improve people's air defence.
As preferably, described remote serial port is RS-485 interface or RS-422 interface.
