Task management is received, United Dispatching earth station equipment, completes the capture of satellite and the reception of satellite data.
Fig. 2 is that the task of the remote sensing satellite ground receiving system of the present invention receives the flow chart of synthetic fault diagnosis method.
As shown in Fig. 2 the method for diagnosing faults of the present invention mainly comprises the following steps：Receive log collection, receiving device information gathering,
Receive digging flow, receive flow diagnostic analysis and receiving device diagnostic analysis.Hereinafter, it is described in detail for each step.
Receive log collection step
As shown in figure 3, pass through the step, event day of the collection remote sensing satellite ground receiving system in task receive process
Will, and be normalized, the event log after processing can be as the input information for receiving digging flow module.Specifically
It is as follows：
1) event log recorded is pushed to fault diagnosis system by station operation management system in real time；
2) before task reception, the information of this subtask is pushed to fault diagnosis software by operation management system of standing, including：
Task code name, satellite name, task start event, task End Event, participate in the information such as equipment that receives；
3) by receiving log acquisition module, all flows letter related to the reception of this subtask is extracted from event log
Breath；
4) because event log is text formatting, and form and disunity, therefore normalizing is carried out by daily record conversion
Change is handled, and is unified for JSON forms；
5) some impurity information are included in the daily record after normalized, such as：Log information, the non-core flow letter repeated
Breath etc., they will influence the performance and uniformity of digging flow, so filtered by daily record, by these Information Filtrations；
6) the final event log after normalized is obtained, and is deposited into database.
Receiving device information gathering step
The equipment that remote sensing satellite ground receiving system receives in task reception period participation task is gathered in this step
Status information, and these information are stored, the diagnosis for carrying out equipment fault is used for after task reception terminates.It is specific as follows：
1) status information of ground satellite station all devices is pushed to fault diagnosis system by station operation management system in real time
System；
2) 1 minute before task reception starts, fault diagnosis system is extracted participation from the status information of all devices and appointed
The status information for the equipment that business receives；
3) mission bit stream is associated with the status information of equipment, and stored.
Receive flow excavation step
As shown in figure 4, by the step, the event log after normalization receive to the excavation of flow,
And as the input information for receiving process diagnosis.Digging flow algorithm uses genetic algorithm in the present invention, specific as follows：
1) event log is read；
2) initial population is created according to heuristic rule；
3) after initial population is created, the fitness of each heredity individual of initial population is calculated；
4) whether evaluation algorithm can terminate, and termination condition has two：A. it has been computed algebraically after maximum；B. produce most
Good causality matrix.If algorithm stops, current population will be returned to, if two conditions stopped being unsatisfactory for, according to certain
The high individual of ratio assignment fitness be natural selection into offspring, the other individuals of offspring to current population then by entering
Row swap operation produces.
Receive flow diagnostic analysis step
As shown in figure 5, the procedural model obtained by excavation describe flow case path and predefined model it
Between, uniformity test is carried out, thus diagnoses whether the case is abnormal, and realization receives the diagnosis of flow, and appoints as final
Business receives the foundation of fault diagnosis.
Receiving device diagnostic analysis step
According to defined fault diagnosis system, equipment that diagnosis participation task receives during tasks carrying whether according to
Correct parameter operation.Fault diagnosis system uses the expertise model based on fault tree form in the present invention.For one
Complicated system, the fault tree of foundation will be very huge, if seriatim checked bottom event, its efficiency it is very low and
It is infeasible.The minimal cut set of fault tree is the minimum set of the bottom event for causing top event to occur, and the present invention is by fault tree
Quantitative analysis and qualitative analysis can obtain most likely resulting in the minimal cut set of top event generation on the basis of probability and be
Which, it is possible thereby to check corresponding minimal cut set, so that it is determined that failure cause.Idiographic flow is as follows：
1) experience of combination failure diagnostic field expert, according to the importance of failure tree node, Chemical Apparatus Importance Classification and failure
The factors such as urgency level, primarily determine that the priority level of each minimal cut set in fault tree；
2) it is automatic to perform receiving device fault diagnosis after task reception terminates；
3) according to failure symptom (top event), a certain fault tree in knowledge base is chosen, according to each event in fault tree
Priority level forward reasoning, find corresponding failure cause (bottom event).
Fault tree models can intuitively describe the principle and process of fault location, be convenient for analysis and the failure of failure
Detail positioning, form fault diagnosis conclusion.Received for remote sensing satellite ground receiving system task, most common phenomenon of the failure is
It is abnormal without original recorded data or original recorded data.The reason for thinking to produce above-mentioned reception failure mainly has day to watch feedback subsystem
Abnormal, channel subsystem exception, data record subsystem are abnormal, referring to Fig. 6.For these three exceptions, The present invention gives event
Hinder tree-model, referring specifically to Fig. 7 to Fig. 9.It should be noted that the reason for data exception is considered as causing to receive failure on star
One of, but the present invention be directed to ground system, therefore data exception does not illustrate in the present invention on star.
It can further include in the method for the present invention and receive task failure diagnostic result generation step.
That is, after task reception, carry out receiving process diagnosis and receiving device diagnosis, after the completion of above-mentioned diagnosis, failure is examined
The result that two classes diagnose is combined by disconnected system, and automatically generating final task in 5 minutes after reception task terminates receives event
Hinder comprehensive diagnos report, this report is pushed to by user by man-machine interaction, the subsidiary conditions of task are received as customer analysis.
The task reception failure that Pass through above-mentioned technical proposal can be seen that the remote sensing satellite ground receiving system of the present invention is comprehensive
Diagnostic method is closed, process diagnosis and receiving device can be received with reference to task according to the characteristics of remote sensing satellite ground receiving system
Diagnosis, fault diagnosis more fully is carried out to task receive process, the cost of system maintenance has effectively been saved, has improved distant
Feel the success rate of satellite ground reception system.
It should be noted that described above is only the preferred embodiment of the present invention, it will be appreciated that for art technology
For personnel, some changes and improvements can also be made on the premise of the technology of the present invention design is not departed from, these are included in
In protection scope of the present invention.
