Description
Technical field
The present invention relates to a kind of wireless communication technology field, especially a kind of satellite communication system of band distal end monitoring.
Background technique
With the rapid development of China's mobile communication cause, mobile communication subscriber amount is just continuously increased, so that cellular plans
Smaller and smaller, base station location is lower and lower；On the other hand, with the high stratification of urban construction, skyscraper is just continued to bring out, by
In the shadow effect of radio transmission, in the behind or the intermediate blind area that mobile communication signal is commonly formed of these skyscrapers.In addition,
Cellular mobile communication base station is in building course, due to consideration that the interference problem of adjacent cell, the radiation field direction of antenna
Figure main lobe has biggish angle of declination, so that skyscraper middle and upper part generally cannot effectively receive signal.Further, since building
Deng to shielding electromagnetic waves effect, so that tunnel, subway, underground commercial center, entertainment city, parking lot and hotel, office building etc. one
Mobile communication signal can not be also normally received in a little closed buildings.
Summary of the invention

The satellite communication system of remote monitoring.
The purpose of the present invention is achieved through the following technical solutions: it includes base station, signal remittance turns unit, monitoring is tieed up
Protect unit and device end；Base station turns unit with signal remittance by radio frequency signal and connect, and signal remittance turns unit and passes through wirelessly
Radiofrequency signal is connect with monitoring maintenance unit and terminal device respectively.
It includes coupler, near-end machine, intermediate frequency antenna, remote termination and retransmitting antenna that the signal remittance, which turns unit,；Coupler
Signal output connect with near-end machine, the signal of near-end machine is exported and is connect with intermediate frequency antenna, and intermediate frequency antenna passes through less radio-frequency letter
It number is connect with remote termination, the signal output of remote termination and the signal of retransmitting antenna are inputted and connected.
The monitoring maintenance unit includes manipulation terminal, monitoring device, radio-frequency antenna and alarm equipment；Radio-frequency antenna
The signal of signal output and monitoring device, which inputs, to be connected, and the output of monitoring device is connect with manipulation terminal, and monitoring device passes through string
Mouth is connect with alarm equipment.
The beneficial effects of the present invention are:
(1) present invention carries out signal remittance turn using proximally and distally two terminals, using intermediate frequency transmission between terminal and terminal
Mode, long transmission distance are influenced small by the external world；
(2) multiple remote terminations can be supported by inventing a near-end machine, and distributed effect, which can reach, preferably to be covered, and remote mountainous area is available
Maximal cover；
(3) invention can carry out quickly networking using two terminals, and near-end machine is placed in base station signal covering, and remote termination can be remote
It is far placed in outside base station range, is particularly suitable for quickly networking and emergency networking after calamity；
