Description
Technical field
The present invention relates to a kind of satellite link and control method thereof, relate in particular to a kind of double-satellite link and control method thereof.
Background technology
Because having worked out point-to-point satellite communication and star network satellite communication at present combines; And the terminal of Hot Spare each other; In order well to solve method of supplying power to this two cover system, just taked rotary switch, the benefit of doing like this can make point-to-point equipment and star network equipment supply power separately; Also can supply power simultaneously, play the effect of Hot Spare.Protection in order better equipment to be powered up in addition, so after mains switch, increased a time-delay relay, the life-span to equipment can prolong to some extent like this.But satellite link can't be selected, and when running into fault, does not possess redundancy feature.
Summary of the invention
The technical problem that the present invention will solve is to propose a kind of double-satellite link and control method thereof to the defective that prior art exists.
Double-satellite link of the present invention, road comprise power subsystem, modulator-demod and control unit; Wherein power subsystem comprises power supply knob, time delay relay and electric power source distribution device, and modulator-demod comprises point-to-point modulator-demodulator and star network modulator-demodulator, and control unit comprises router and serial server; The time delay relay is connected with the power supply knob through power line, and the time delay relay is connected with electric power source distribution device through power line; Point-to-point modulator-demodulator is connected with the star network modulator-demodulator through netting twine and router; Router is connected with serial server through netting twine; Electric power source distribution device through power line be connected with the star network modulator-demodulator with point-to-point modulator-demodulator respectively, the connection of router and serial server; Point-to-point modulator-demodulator is connected with serial server through Serial Port Line, and router is connected with point-to-point modulator-demodulator and star network modulator-demodulator respectively through netting twine.
The control method of described double-satellite link comprises the steps:
A) select the power supply powering mode, duplex feeding or one tunnel power supply;
B) turn on the power switch, whether checkout equipment normally starts;
C) do not start when equipment is normal, then wait for operation; When equipment normally starts, then whether antenna receiving signal detects modulator-demodulator and normally reaches the standard grade via satellite;
D) normally reach the standard grade when modulator-demodulator, then the Switching power powering mode; Normally reach the standard grade and normally to reach the standard grade when modulator-demodulator, then wait for operation.
When the present invention was broken down when a kind of satellite means, another road satellite system can provide safeguard by Hot Spare.Simultaneously can select to add point-to-point satellite communication system still is the star network satellite communication system.

Embodiment
As shown in Figure 1.A kind of double-satellite link comprises power subsystem 1, modulator-demod 2 and control unit 3; Wherein power subsystem 1 comprises power supply knob 11, time delay relay 12 and electric power source distribution device 13, and modulator-demod 2 comprises point-to-point modulator-demodulator 21 and star network modulator-demodulator 22, and control unit 3 comprises router three 1 and serial server 32; Time delay relay 12 is connected with power supply knob 11 through power line, and time delay relay 12 is connected with electric power source distribution device 13 through power line; Point-to-point modulator-demodulator 21 is connected with star network modulator-demodulator 22 through netting twine and router three 1; Router three 1 is connected with serial server 32 through netting twine; Electric power source distribution device 13 through power line be connected with star network modulator-demodulator 22 with point-to-point modulator-demodulator (21) respectively, router three 1 and serial server 32 connections; Point-to-point modulator-demodulator 21 is connected with serial server 32 through Serial Port Line, and router three 1 is connected with point-to-point modulator-demodulator 21 and star network modulator-demodulator 22 respectively through netting twine.
The control method of described double-satellite link comprises the steps:
A) select the power supply powering mode, duplex feeding or one tunnel power supply;
B) turn on the power switch, whether checkout equipment normally starts;
C) do not start when equipment is normal, then wait for operation; When equipment normally starts, then whether antenna receiving signal detects modulator-demodulator and normally reaches the standard grade via satellite;
D) normally reach the standard grade when modulator-demodulator, then the Switching power powering mode; Normally reach the standard grade and normally to reach the standard grade when modulator-demodulator, then wait for operation.
Double-link backup method of the present invention is selected to supply power to two cover satellite systems simultaneously when selecting the power supply powering mode, and when its traditional Chinese medical science satellite system broke down, another set of system will transfer application system to automatically, makes satellite link not be interrupted.
