Description
Technical field
The utility model relates to a kind of satellite link, relates in particular to a kind of double-satellite link based on the time delay relay.
Background technology
Owing to worked out point-to-point satellite communication and star network satellite communication combination at present, 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 power separately, also can power simultaneously, play the effect of Hot Spare.Protection in order better equipment to be powered up in addition, so increased a time-delay relay after mains switch, the life-span to equipment can prolong to some extent like this.But satellite link can't be selected, and does not possess redundancy feature when running into fault.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of double-satellite link based on the time delay relay at the defective that prior art exists.
A kind of double-satellite link of the utility model based on the time delay relay, the road comprises 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 by power line, and the time delay relay is connected with electric power source distribution device by power line; Point-to-point modulator-demodulator is connected with the star network modulator-demodulator by netting twine and router; Router is connected with serial server by netting twine; Electric power source distribution device by power line be connected with the star network modulator-demodulator with point-to-point modulator-demodulator respectively, router and serial server connect, point-to-point modulator-demodulator is connected with serial server by Serial Port Line, and router is connected with point-to-point modulator-demodulator and star network modulator-demodulator respectively by netting twine.
When the utility model broke 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.
