Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of be applied in the digital home network both can be according to the rule of customization, also can come the automatic adjustment system behavior, and can effectively handle the context affairs sensory perceptual system of the conflict of the two according to the rule of knowledge base.
Another object of the present invention is to according to this sensory perceptual system, a kind of context affairs cognitive method is provided.
In order to realize goal of the invention one, the technical scheme of employing is as follows:
A kind of context affairs sensory perceptual system that is applied to digital home network, adjust the behavior of digital family network appliance by the perception transaction information, comprise transaction management module, context management module, condition parsing module, trigger administration module, information fusion module, automatic processing administration module and context database and knowledge base;

Described condition parsing module also is connected with the triggering administration module;
Described automatic processing administration module also is connected with the information fusion module;
Described context database also is connected with condition parsing module, automatic processing administration module, information fusion module, knowledge base respectively;
Described knowledge base also is connected with the information fusion module.
In the technique scheme, the affairs of institute's perception comprise by the customization affairs of the concrete rule of customization and the automatic processing that comes out by the knowledge base reasoning.
Described context database store customized transaction model.
The customization transaction model that described context database is stored comprises also unenforced affairs that the user sets and the historical affairs of having carried out.
Described transaction model is abstract turn to Task (C, A), wherein C is the set of affairs trigger condition, A is the set that affairs trigger behavior.
Adopt said structure, the concrete function that module realized is as follows:
Described transaction management module is the person of sending that the present invention adjusts self behavior command, also is the recipient of customization affairs simultaneously.Generation, customization, conflict management and affairs that it is responsible for affairs trigger.The present invention adjusts the dual mode that sent of self behavior command: one, and the affairs of customization are when having satisfied various trigger condition; Two, after the contextual information that knowledge base transmits according to bottom is dealt with, submitted one or more system's adjustment instructions to, i.e. automatic processing.
The customization affairs that can provide are the abstract transaction model that a correspondence is arranged in context database all, and each concrete customization affairs through quantizing is exactly an example of abstract transaction model.Administration module offers the user with these abstract transaction model, and user's customization procedure is exactly the process that each component in the abstract model is quantized.For example: have an abstract transaction model to be expressed as in the context database: Temperature ﹠amp; Its expression of Time → Air-conditioning is adjusted the state of air-conditioning when temperature and time satisfies certain condition.That is: trigger condition C1=Temperature, C2=Time; Triggering behavior A=Air-conditioning; The user from certain intelligent terminal (as mobile phone) to system customization the process of affairs of this type be exactly the process that quantizes each component, such as: the customer requirements system is lower than 20 ℃ in temperature, and the time is at night the time, automatically air-conditioning is beaten the warm state of the system of being adjusted into.The transaction management module is accepted this customization affairs, decomposites trigger condition and triggering behavior, and the triggering behavior is inserted into triggering behavior formation, trigger condition is submitted to the condition parsing module of lower floor.When trigger condition satisfied, the transaction management module caused the relative trigger behavior.Also should customize affairs simultaneously and deposit in and ask up and down in the database, store as contextual history.
The transaction management module is divided into trigger condition and triggering behavior with all customization affairs, but to automatic processing, only accepts it and trigger the behavior part.Because automatic processing is based on the behavior that the rule-based reasoning of knowledge base comes out, these rules can be the statistical rules that comprises user's history, basic general knowledge rule and the reasoning of artificial intelligence.
The condition parsing module is accepted the trigger condition part of each customization affairs of transaction management module submission, and is mutual with context database, decomposites each detailed trigger condition, and corresponding each customization affairs all decomposite a trigger condition chained list.Decomposition is come out each chained list information to triggering the administration module submission.
Trigger administration module the trigger condition data in each chained list are carried out data application and inquiry to the context management module of lower floor, and each trigger condition is judged.When all conditions in inquiring certain customization affairs chained list all satisfies, send the message that to carry out the triggering behavior to the transaction management module.
Context management module is assigned to the upper layer data application on each transducer, accepts each data that sensor sensing is arrived.Data are carried out necessary normalizing and standardization formation context data.These context datas offer on the one hand and trigger the administration module inquiry, carry out the triggering of customization affairs and judge.On the other hand, will be delivered to the information fusion module, carry out the analysis of automatic processing trigger condition, form relevant automatic processing.In actual applications, context management module can also manage transducer, and as the location management of transducer, licking of transducer adds deletion management, the Classification Management of transducer.
The function of information fusion module is according to the reasoning of knowledge base and the history of user's context, and the contextual information system that is converted into is adjusted the instruction set of self behavior, just automatic processing.Because the contextual information submitted of context management module has been represented the state information of current system, these information have comprised time, temperature, light, sound size, network traffics, but these information comprise that to be not have indication semantic.So change into control command by the information fusion module, in each adjustment cycle, the information fusion module all will produce an automatic processing and these affairs will be submitted to the automatic processing administration module, and under the situation that contextual information does not have to change, these affairs are empty.
Triggering behavior between a plurality of automatic processings, and have between the triggering behavior of the triggering behavior of automatic processing and customization affairs and have conflict possible.Such as being lower than 20 ℃ when temperature, the time, according to the affairs triggering rule of customization, it was warm then should to open air-conditioning system when being evening.Suppose and have such reasoning in the knowledge base: family nobody the time, air-conditioning is not opened, so when even temperature and time all satisfies condition, if sensor to home nobody the time, the triggering behavior of automatic processing is to close air-conditioning.The triggering behavior and the automatic processing of customization affairs here clash.One of them function of automatic processing administration module solves these conflicts exactly, when clashing between affairs, the automatic processing administration module effectively manages conflict according to rule, these rules can be that the triggering behavior of simple user customization affairs is preferential, promptly in case clash the behavior of then cancelling or delaying to trigger automatically.More intelligent rule then will be based on the knowledge base reasoning of artificial intelligence and the optimization criteria of system action.Therefore the automatic processing administration module is adjustable upgradeable module.The triggering behavior of the automatic processing that will handle through conflicting is submitted to the transaction management module, sends system's adjustment instruction by the transaction management module.
Context database has determined the type of the customizable affairs of user, and these types can be formulated by user oneself, and along with the upgrading of system, the transaction types that can provide also is corresponding the variation.Context database has also been stored user's contextual history, i.e. the affairs that once customized of user, detail record the numerical value of each component of things trigger condition and behavior.The affairs of customization as described above will be recorded as in the storehouse: trigger condition: Temperature=20 ℃, and Time=evening; Triggering behavior: open warming by air conditioner.
Knowledge base is storage inference rule and carries out the intelligence base that contextual information transforms to the behavior that triggers automatically.The reasoning of knowledge base can be based on commonsense reasoning, as: same individual can not be not only in the kitchen but also in the bedroom; Also can be the reasoning of opportunity user historical statistics, as: 10 just sleeps in user's evening.Based on this statistical rules, system will be at night 10 turn off TV later on.The statistical rules of historical record is a process of constantly adjusting, and forms metastable inference rule according to user's custom the most at last.
In order to realize goal of the invention two, the technical scheme of employing is:
