Description
Technical field
Present invention is mainly used for satellite systems, especially with the satellite of double response machine system.
Background technique
Spaceborne TT&C Transponder be star communicate an important component in main channel.Generally speaking, observing and controlling response
There are five major functions for machine:
1. receiving and demodulating the command signal of earth station or relay satellite system transmission, and pass at spaceborne computer
Reason；
2. tracking and coherent forwarding earth station uplink emitting carrier wave, Doppler frequency shift is carried out for earth station and is tested the speed calculating；
3. the side-tone ranging signal for receiving, demodulating and earth station's uplink is forwarded to send, carries out distance calculation for earth station；
4. receive the telemetry intelligence (TELINT) from spaceborne computer, scrambling plus adjust after by wireless channel pass to earth station or in
After satellite system.
5. providing a stabilized carrier signal for earth station, tracking is carried out convenient for earth station and surveys rail.
Once answering machine disabler, it will directly lose the control to satellite.
There are mainly two types of existing anti-answering machine defeat techniques, first is that answering machine internal autonomy judges itself working condition,
If being in malfunction, answering machine passes through watchdog circuit from master reset.Second is that utilizing AGC voltage value, uplink remote control locking
The parameter states such as instruction, out-hole run frame count are independently judged and from master resets.
Summary of the invention
The purpose of the present invention is to provide a kind of methods that low orbit spacecraft prevents double response machine from failing, and use program control command
Answering machine A/B is controlled, double response machine disabler is prevented, to greatly improve answering machine reliability of operation and safety.
In order to achieve the above objectives, the invention is realized by the following technical scheme:
A kind of method that low orbit spacecraft prevents double response machine from failing is sent program-controlled by spaceborne computer or integrated electronics
Instruction control answering machine A/B booting, shutdown and reset, prevent function caused by the equal power down of answering machine A/B or single event latch-up from losing
Effect, specifically,
The spaceborne computer control every rail timing reset of answering machine A/B is primary, successively sends program-controlled reset to answering machine A/B and refers to
It enables；
The spaceborne computer control daily timing start-up of answering machine A/B is primary, successively sends program-controlled booting to answering machine A/B and refers to
It enables；
Spaceborne computer control answering machine A/B restart under certain condition, to answering machine A/B successively send it is program-controlled shutdown and
Power-on instruction.
Wherein, primary program-controlled reset instruction was sent to every answering machine when spaceborne computer judges the South Pole；Answering machine A exists
After receiving reset instruction 300 seconds, spaceborne computer starts to send reset instruction to answering machine B.
Wherein, primary program-controlled power-on instruction was sent to every answering machine in spaceborne computer every 24 hours；Answering machine A is being received
To after power-on instruction 30 seconds, spaceborne computer starts to send power-on instruction to answering machine B.
Wherein, uplink remote-control data is not received within spaceborne computer 28 hours, program-controlled shutdown is successively sent to two answering machines
It is allowed to restart with power-on instruction；Answering machine A is after receiving primary program-controlled shutdown command 5 seconds, and spaceborne computer is continuously to response
Machine A sends three program-controlled power-on instructions, and command interval 1s completes answering machine A and restarts, after 100 minutes, the same sample prescription of spaceborne computer
Method completion answering machine B is restarted.
Compared with prior art state, the present invention can prevent double response machine from failing from whole star level, guarantee at least all the way
Remote-control romote-sensing link is unimpeded, substantially increases answering machine reliability of operation and safety, and then improve whole star reliability and peace
Quan Xing, and the advantage simple, easy to accomplish, at low cost with structure.
Detailed description of the invention
Fig. 1 is the schematic diagram for the method that a kind of low orbit spacecraft of the embodiment of the present invention prevents double response machine from failing.
Fig. 2 is the flow chart for the method that a kind of low orbit spacecraft of the embodiment of the present invention prevents double response machine from failing.
Specific embodiment
In order to which objects and advantages of the present invention are more clearly understood, the present invention is carried out with reference to embodiments further

As shown in Figure 1, passing through the embodiment of the invention provides a kind of method that low orbit spacecraft prevents double response machine from failing
Spaceborne computer (or integrated electronics) sends program control command control answering machine A/B booting, shutdown and resets, and prevents answering machine A/B
Disabler caused by equal power down or single event latch-up；Specifically,
As shown in Fig. 2, the spaceborne computer control every rail timing reset of answering machine A/B is primary, to every when judging the South Pole
Answering machine sends primary program-controlled reset instruction.After receiving reset instruction 300 seconds, spaceborne computer starts to answering answering machine A
It answers machine B and sends reset instruction.
As shown in Fig. 2, the spaceborne computer control every 24 hours timing start-ups of answering machine A/B are primary, successively to answering machine A/B
Program-controlled power-on instruction is sent, after receiving power-on instruction 30 seconds, spaceborne computer starts to send to answering machine B to be opened answering machine A
Machine instruction.
