Fig. 2 is the information flow chart that a kind of satellite telemetering data is unified in immediate processing method offline, and task scheduling is whole
The core of example, realizes the control to whole off-line process, to thread scheduling service, process service, data sieve after startup
Choosing service, interface service, data analysis service and file service carry out example initialization.Process the service of service response thread scheduling
Management, complete parallel data under thread scheduling and process service, data processing service and data screening service carry out data
Interaction.Data screening service is screened to remote measurement true form data according to the parameter of task scheduling modules after instantiation, with place
Reason service screened after data interaction.Thread scheduling service to process service data screening service and file service it is multi-thread
Cheng Liucheng is managed.Interface service after instantiation carries out configuration parameter data with user and interface and interacts.File service is received
The management of thread management service, is interacted with remote measurement true form data, while also carrying out result with data analysis service
Interaction.
In satellite offline data handling procedure, user can carry out stopping, the startup of handling process service by interface operation
Deng operation, task scheduling service is performed according to operational order, control flow.In implementation procedure, removing in suspending to interface service
Instruction outside Row control it is corresponding, there is the phenomenon of data processing inconsequent in preventing from servicing.
The satellite telemetering data of the present invention unifies the unified interface model of immediate processing method offline as shown in figure 3, being directed to
Different satellites, processes describing mode to realize different model using the remote measurement of identical data processing dynamic link library and standard
The concordance of interface.
As the data processing of the present invention adopts the pattern of parallel processing, therefore there are multiple data processing units, each
Data processing unit registers a dynamic link library, and after succeeding in registration, control flow example enters to data processing module
Row is called, and realizes the parallel processed offline of satellite telemetering data by multithreading.
Using unified dynamic chanining bank interface by the way of can greatly improve data processing between different satellites
Motility, realize docking with processed offline method only with standard interface.The interface of standard is using to dynamic link library one
Frame completes telemetry and the telemetry intelligence (TELINT) that need to be processed, and provides the data after the process of consolidation form, the reticle after process
Formula include remote measurement code name, remote measurement true form, process after physical quantity, length information and display mode, user's output module is according to these
Information is organized to result, exports into the complete result information after process.Dynamic link library can adopt unified process frame
The mode of structure and script realizes the process and configuration of different satellite telemetry information, can greatly improve in this way
The reusability of different satellite data off-line processing systems, the remote measurement of standard process describing mode by the way of script to distant
Measurement information is described, and including telemetry channel description and the description of remote measurement processing method, is realized at satellite data in this way
The uniformity of reason interface.
The true form of the present invention is obtained and data processing parallel model is as shown in figure 4, remote measurement true form is extracted and data processing is adopted
With three independent threads, wherein data screening carries out the reading of true form file using independent thread and writes round-robin queue
In, whether round-robin queue is completely judged before write, if discontented, write at once, if full, carry out wait mould
Formula, until queue is non-full, then proceeds write queue and data screening operation, and the thread adopts burst mode of operation.At data
Reason unit is two independent threads, carries out parallel processing under the control of administrative unit, using parallel place in processing procedure
The mode of reason ensures the seriality of data processing unit work, and this preference is using double-core CPU process, therefore adopts two-wire
Journey tupe, for multi-core computer, can increase the number of data processing unit to significantly improve treatment effeciency.Data are defeated
Go out module to reorganize the data after data processing unit processes, exported after sequence.
Administrative unit is also responsible for being managed the mistake of data processing unit, including time-out management and process mistake pipe
Reason, time-out are, when the long then interrupt processing of duration, to process again present frame, and fault processing includes abnormality processing and repeatedly super
When process.It is as the handling process of different model may have Deviant Behavior in processes, abnormal existing to what is occurred in processing procedure
As being processed, frame process is skipped while error message is recorded, be easy to problem analysis.Repeatedly timeout treatment refers to one
Repeatedly there is overtime phenomenon in frame process, skip process to the frame while error message is recorded, be easy to subsequent analysis to occur
Overtime the reason for.
Parallel process model of the present invention as shown in figure 5, parallel processing mainly include Four processes, first receive process please
When asking, all process threads are inquired about, whether inquiry is free idle thread, is waited, directly if no idle thread
Process task is distributed to into the thread to being after free idle thread, after there are data processing threads to complete data processing, then will be processed
Measurement telemetry information transmission afterwards is to data outputting module, while when now there is data processing request, then will work as secondary data and appoint
Business is distributed to the thread and is processed.Usually, the process time per frame data is roughly the same, therefore data processing task is divided equally
Into each data processing threads.
In addition to it will carry out the function that task distribution and result are obtained, administrative unit is also needed to data processing threads
Run time and ruuning situation are managed.It is long between when running, then terminate currently processed, re-start task distribution, when
Task is redistributed number of times and then abandons this process and time-out is recorded more than the threshold value for setting.When operation thread occurs
Exception exit or mistake when, carry out error trapping, restart thread and mistake is recorded, at the same administrative unit be also responsible for it is right
Round-robin queue conducts interviews control, and output result is delivered to data outputting module.
One skilled in the art will appreciate that except the system for realizing present invention offer in pure computer readable program code mode
And its beyond modules, completely can by by method and step carry out programming in logic cause the present invention provide system and its
Modules are in the form of gate, switch, special IC, programmable logic controller (PLC) and embedded microcontroller etc.
To realize identical function.So, the system and its every module that the present invention is provided is considered a kind of hardware component, and right
The structure that the module for realizing various functions included in which can also be considered as in hardware component；To can also be used for realizing respectively
The module of kind of function is considered as can be not only the software module of implementation method but also can be the structure in hardware component.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or change, this not shadow
Ring the flesh and blood of the present invention.In the case where not conflicting, the feature in embodiments herein and embodiment can any phase
Mutually combine.
