Referring to concrete composition knot of Fig. 2 descriptions as the interpretation reasoning module of the core of the interpreting system of the present invention
Structure.
As shown in Fig. 2 it may include that pattern matcher, agenda manager and execution are drawn according to the interpretation reasoning module of the present invention
Hold up.Wherein, pattern matcher is used to select the multiple rules used in spacecraft data interpretation.When pattern matcher selection
When multiple rules have execution conflict, adoption of the agenda manager determines multiple regular priority, and will be multiple regular according to excellent
First level is put into agenda.Then, the priority orders that enforcement engine determines according to agenda manager, executing rule is to spacecraft successively
Data carry out automatic interpretation, until strictly all rules performs completion, and draw interpretation conclusion.
Further, agenda manager can determine multiple regular preferential according to the Stringency of multiple regular conditionals
Level order, condition Stringency highest rule have highest priority.For example, regular A Rule of judgment only has one, and
Regular B Rule of judgment has two, then regular B condition Stringency is higher than regular A.
However, it will be understood by those skilled in the art that the method for above-mentioned determination priority orders is only a kind of exemplary
Method, the mode of other determination priority can also be selected according to actual conditions.
When spacecraft data automated interpretation system starts, the rule stored in knowledge base is loaded into positioned at internal memory first
In the blackboard area in area.Then, spacecraft data automated interpretation system receives spacecraft data by network from data processing module,
Data are parsed after receiving (such as formula conversion processing).Hereafter, what interpretation reasoning module was locally stored sentences
Read configuration information, including the type of service and other configurations information that interpretation is taken.Then, by pattern matcher from blackboard
Multiple rules that this data are carried out with interpretation are selected in the backup rules in area, if multiple rules have conflict, are passed through
Agenda manager solves conflict, i.e. determine multiple regular priority, and then by enforcement engine according to priority orders successively
Multiple rules are performed, interpretation conclusion is drawn after having performed strictly all rules.
Further, spacecraft data automated interpretation system of the invention can also include interpreter.In interpretation reasoning mould
After block draws interpretation conclusion, interpretation conclusion is sent to interpreter, interpreter interpretation conclusion is provided an explanation, illustrate interpretation conclusion
The reasons why drawing.Interpretation conclusion is respectively sent to conclusion display module by interpreter afterwards and conclusion memory module is shown respectively
Show and store.
In the present embodiment, interpretation reasoning module or interpreter are connected by communication interface with conclusion display module,
Interpretation reasoning module or interpreter send interpretation conclusion to conclusion display module by way of udp broadcast, are shown in conclusion
Interface is by interpretation conclusion real-time display to user.The content that conclusion display module is shown can include：Parameter interpretation, instruction are sentenced
Read, instruct monitoring, event interpretation and event monitor.
In the present embodiment, after interpretation conclusion is obtained, conclusion memory module receives interpretation reasoning module or explanation
The sentence read result of device broadcast, and interpretation conclusion is preserved according to the requirement of configuration file, so that the access of user in the future uses.
