Description
Technical field
The present invention relates to a kind of method that industrial project or production are monitored and are managed more particularly to a kind of description things
Object space attribute and the method searched based on the description.
Background technology
Database Development experienced level, netted, relationship type and non-relational database to today.Database at
For the essential system of data storage and query, now, there are also so-called space-time databases, and mainly GIS (
Manage information system) borrow the progress data storage of relationship library.Relational database is built upon the database on the basis of relational model, borrows
Help the mathematical concepts such as algebra of sets and method to handle the data in database.Various entities and entity with the real world
Between various contacts indicated with relational model.Relational model refers to just two-dimensional table model, thus a relationship type number
According to library be exactly by bivariate table and its between a data organization forming of contact.The relevant database of current main-stream has
Oracle, Microsoft SQL Server, MySQL etc..
In industrial production monitoring and management domain, there are SCADA monitoring, real-time data base, relationship library, non-relationship of also increasing income
The application in library, there are no the functions that a kind of database can improve these types of database, and can be realized with configuration.Database
(Database) it is to come tissue, storage and the warehouse for managing data according to data structure.Spatial database refers to geography information
The summation with the relevant geographical spatial data of application that system stores on computer physical storage medium, usually with a series of
The form group of the file of specific structure is woven on storage medium.
Spatial database identifier space information numerous at present is all to support spatial information using storage coordinate information, is added
It is upper to provide index using a self-propagation ID (Identity, sequence number), it needs to come by space structure algorithm in search
It realizes.To solve the above problems, many patents can simplify space number by using simpler Spatial Data Index Technology now
According to library field structure, the memory space of occupancy is saved.
Chinese patent (CN102622349B) discloses a kind of processing method of spatial position information database, and feature exists
In the processing method of the spatial position information database includes：Obtain the coordinate data of a spatial position；According to the coordinate
Data generate spatial positional information coding corresponding with the spatial position；The sky is stored in spatial position information database
Between location information encode, by spatial positional information coding as spatial position index in the database and position
Confidence ceases..In said program, the problem is that：(1) not high enough to spatial description accuracy, accuracy, such as in factory
A certain upper side, bottom can not accurate, differentiation descriptions；(2) space analysis and coding be not square for the inquiry of data and calling
Just, for example factory's boiler working condition is checked, it is also necessary to go for the corresponding coding of the boiler, cannot directly be inquired；(3) when
After physical location update changes, database is updated without dynamic.
Relevant database is stored in the set of on computer, sharable, organized relational data.Relationship
Type data are the data to indicate with relationship mathematical model, and data are described in the form of bivariate table in relation mathematic model.
In application system using relational data library storage information, there are the inquiry of a large amount of various dimensions, this kind of inquiry provides a variety of
The querying condition of dimension is inputted for user, while user needs information that is simple, quickly, intelligently retrieving needs.It is right
The optimization method of data base querying is mainly the following：(1) index is rationally utilized：To the tables of data in relational database, press
It is queried field and creates independent orderly storage organization, it is similar to create directory to books, it trades space for time, improves inquiry property
Energy.(2) redundancy relationship data：Data Structure Design in relational database need to follow certain specification, to ensure the complete of data
Whole property and consistency, and reversed standardization is suitably taken, the information in the other correlation tables of redundant storage in bivariate table is looked into reducing
Incidence relation when inquiry improves query performance.(3) separation storage mass data：For mass data, divided by certain data
Class separate storage increases service logic complexity, improves application if telephone number information is stored respectively by affiliated area
The design difficulty and data maintenance difficulty of program, but query context is reduced, query performance can be improved.
Chinese patent (CN100483411C) discloses information retrieval method in a kind of relevant database, including step：
Construction dimensionality reduction strategy tree is placed in Database Systems, and the dimensionality reduction strategy tree includes at least one child node and extremely
A few root node, each child node include at least this node number-mark information and enquiry condition combination information and subordinate's sub- section
Point number；When not obtaining required data by user's querying condition retrieval database, successively according to dimensionality reduction strategy tree
Construct new querying condition；According to new querying condition searching database until obtaining required data or inquiring dimension reduction
The root node of Policy Tree returns to the information without required data.The invention also discloses information retrievals in a kind of relevant database to fill
It sets, including：Querying condition acquiring unit, query result output unit, Policy Tree storage unit and inquiry operation unit.It utilizes
The invention can improve database retrieval efficiency.However, the patent the problem is that：Spy is needed when inquiry and calling data
Fixed number-mark information, in certain fields, such as industrial process control field, the type and quantity of equipment and procedure parameter are all
Very much, very inconvenient using number inquiry data.This is the problem of traditional relational exists always --- each object must
Corresponding data must can be just retrieved by unique corresponding identification code.If there is a kind of method can directly pass through the position of equipment
Or the time point where procedure parameter is retrieved, recall precision can improve very much.

Specific implementation mode
It is described in detail with reference to embodiment.
The present invention provides be related to a kind of method for describing things space attribute and being searched based on the description.The party
Method is realized by a kind of space-time database.The space-time database stores the meter in the production process of enterprise or detailed programs
It draws, real-time and historical data, corresponds to three databases respectively, three databases are used to store enterprise's prospective project data,
Product practice and historgraphic data recording.Each data include time and space attribute.Inside the space-time database at least
It is divided into three databases：Historical data, real time data, planning data.Real-time data base is used for storing the instantaneous value of current system；
Historical data base carries out the storage of historical data according to the condition of configuration；Plan database is used for storage plan data.Thing is described
Object space attribute simultaneously realizes that the method that things is searched can be based on the realization of following device, specially：It is built by spatial object editing machine
Vertical multistage spatial object, and temporally attribute is separately stored in by the corresponding multistage spatial object of each component of things to be described,
Real-time data unit, historical data unit and planning data unit.User is based on by the spatial object information of things to be described,

At least store historical data base.The planning data unit at least stores plan database.The interactive module is at least wrapped
Include such as keyboard, mouse, touch-screen display, speech input output device and image input-output equipment.
The time dimension of description creation data is divided into past, present and future.Three kinds of databases data storage with
Realization method all differs.Wherein, plan database includes multiple data contents or multiple numbers for same time and space
According to version.Plurality of data content or multiple versions of data are related to for the different plans corresponding to different real time datas
Data.It is directed to triggering or the matching process of real time data.The plan database is based on real time data and completes data-triggered
Or matching process, to realize the matching planning data of corresponding trigger data.Wherein, real time data has very high real-time,
The real time data of the corresponding up to a million records refreshed per second, has the data not refreshed in time the limitation of fresh phase.
Historical data majority is time series data, and the time series data, which can be done, to be compressed and store, and also has the uncompressed of business datum certainly
Storage.
Space-time database describes the data information of production monitoring management by three sections of time dimensions, is solved by a library
The problem of multiple systems are applied, can reduce the investment of user and the maintenance cost of system.Different from pressing ID according to level library
The SQL query in retrieval or relationship library, according to the object of some model of time and space querying, this issuer when data query
Formula is user's mode the most known, naturally also easily.The shown space-time database things to be managed user is taken out
As summarizing, each things is a data object to be stored, and it is same that the similitude of things determines that they can come from
A model, but things is also variant with things transition, the management that may be implemented to store things by the version of model,
The data of current things can not only be looked into when inquiry can also find things transition, and empty database can pass through version when in use for these
This control is realized.
The data packet of the database purchase contains having time and space attribute, and the time is the indivisible attribute of object.Example
Such as, an engineering or project, if space-time system changes, it is meant that the reconstruction of engineering or project.Time and space have
Position, length (granularity).For example, production batch is exactly a kind of length, the information of some workshop first batch.It does not spend and writes some
Period goes to obtain possible batch information.Because of the spatial information of the present invention, we can pass through when display data
Space representation function is directly shown in the form of geography information.The object of same model instantiation, if their time
Position, spatial position, time span, space length are all identical, then they must be same target.
The space-time database implementation process includes modeling process to thing and/or object or data and is carried out to model real
Exampleization process.Model can solve the description of identical structured data object very well, can quickly be instantiated by model, towards right
As programming is abstract expression and the description to a class object itself.In configuration software industry, being widely used for data model is general,
There are also simple calculating logics for some models itself, this only solves the calculating of model internal members, model and model
Between be not carried out calculating, not only want in actual application inside computation model calculating also have model between calculating.
The modeling process to thing and/or object or data, including spatial modeling process and time modeling process.The sky
Between modeling process include being modeled to it according to the spatiality of object to be managed.I.e.：Space according to object to be described,
State determines multistage spatial object.Preferably, geography information coordinate system, the geography information are loaded by spatial object editing machine
Coordinate system can be the electronic maps such as Google Maps, Baidu map.For example, by spatial object editing machine load Google Maps or
Person's Baidu map draws the spatial dimension of a Root root node based on factory geographic location, in the sky of Root root nodes
Between draw a spatial object with rectangle/irregular polygon line/point/broken line to obtain first order spatial object in range.It is excellent
Selection of land draws a spatial object to obtain the in first order spatial object with rectangle/irregular polygon line/point/broken line
Secondorder spatial object is until (n-1)th grade of spatial object, in (n-1)th grade of spatial model with rectangle/irregular polygon line/
Point/broken line draws a spatial object to obtain n-th grade of spatial object.By the spatiality and spatial model of object to be described,
Corresponding matching, to realize to the factory of entire project, workshop and the spatial information mark for generating line even mechanical equipment.
The spatial object is a kind of relationship of level, and the most important feature of spatial object, which is the range of subobject, to be surpassed
Cross parent object.One father's spatial object can have multiple sub- grade spatial objects, and one sub- grade spatial object can only there are one father's skies
Between object.Spatial object is that the spatial object includes the sky of physical object
Between shape, spatial dimension and the description of spatial position.Real space position of the space in addition to expressing actual physical object
The compass of competency of a unit, such as some group can also be expressed, he is made of several branch companies, is had under these branch companies
Several factories are constituted.There is an actual spatial position in each factory, and although there is a company building in branch company, but the space of branch company
Range is the outer edge profile in factory and building.The spatial dimension of group is the outer edge profile for more having branch company.
Space is a kind of positioning of position attribution, and all things were made of time and space, and space is main still
There are the attributes such as spatial granularity, spatial dimension, spatial position.The spatial information that space attribute is provided to describe dynamic static object is deposited
.The drawing process of spatial object is not only described.
According to a preferred embodiment, geography information coordinate system, the geography are loaded by spatial object editing machine
Information coordinate system can be the electronic maps such as Google Maps, Baidu map, can also be the coordinate-system being manually entered.According to sky
Between attribute separate feature to be marked is marked to the corresponding position of figure layer, while marking the sky of the longitude of things, latitude and height above sea level
Between attribute information, and mark things build-in attribute.Described information annotation process includes label character and figure labeling, wherein scheming
Shape annotation process, user can draw a spatial object, this spatial object with rectangle/irregular polygon line/point/broken line
With regard to it is corresponding be first order spatial model, such as factory, drawn factory, can be this pattern visual evoked potentials of factory, inside again
Workshop is drawn, or imports factory's CAD diagram paper, the factory of entire project, workshop and generation line even machinery are set to realize
Standby spatial information mark.According to another embodiment, the space bit of things can also be realized by modes such as place name, road signs
Set mark, such as the first workshop, the second assembly line, 3rd station, boiler room, boiler implosion room, boiler attendance room, boiler are spare
The specific location etc. of part storehouse, boiler top, boiler bottom, spare part in boiler room.To avoid space coordinate label complicated
The complicated characteristic with retrieval.
Based on spatial object, user may be implemented to complete by the space attribute information of the longitude of things, latitude and height above sea level
The retrieval of corresponding position things, to check historical information, real time information and the plan information of the position things.Meanwhile it using
Family directly can also realize that the spatial position of things marks by modes such as the logical location informations of things, such as place name, road sign.
Can be specifically：First workshop, the second assembly line, 3rd station, boiler room, boiler implosion room, boiler attendance room, boiler are spare
The logical place description of the things such as part storehouse realizes that things is searched.
Computation model and data model are also the basic model for constituting the space-time database, are wrapped in the space-time database
Model library when containing exploitation and engineering library, the real-time, history, plan library when operation and computing engines.Information System configuration is divided into
Solution stage and engineering phase, solution stage are mainly to carry out determining for data model and computation model in model library
Justice, engineering phase is in curstomer's site installing engineering library, example again after the relational data model and computation model in stress model library
Change object, these objects are specified in the operation of some machine node, these machine nodes can automatic installation and deployment we real-time
Library, history library and plan library and calculating task.
The structure of the data model is the abstractdesription for managing real world things.Things has time and space
The system of build-in attribute, monitoring has the requirement of security permission.So the primary attribute of data model include title, security model,
The compositions such as time model, spatial model, data direction, storage mode, founder, creation time, modification time.Primary attribute is
It is intrinsic, do not need user and individually create, some attributes be automatically generated such as founder, creation time and modification time, have
Must configure, do not complete configuration data model be unable to normal use.The member of data model is user-defined, member
There are title, type, unit, initial value.The type of member is provided by system, and user is allowed to select, member type include the time, space,
Number resource, is enumerated, a series of objective datas such as audio, video, file, if the existing digital information of plan, and would have sound
Video information, the type that we can define multiple members of this planning data model are int respectively, float, audio and
Video, file etc..
Each model has unique time granularity and spatial granularity, by taking a planning data as an example, describes one
Production line running-plan, production line model and shift model be realize definition spatial model and time model, model determine with
Assume that production line model has 3 production line objects, class's model there are the first and second the third class Threes in engineering phase afterwards.So data model can only
It instantiates 3 production lines, 3 teams and groups and amounts to 9 planning data objects, the plan of other space-time granularities cannot be instantiated.Model
Time granularity and spatial granularity cannot modify again after determining, only having modified attribute or change member can just generate newly
Model version.
The member of the data model changes, and the attribute in addition to time and space occurs change and just will produce new version.
Space-time database allows a model, and there are multiple versions.It is illustrated with the production equipment in workshop, in the actual production process, is met
Face the upgrading of equipment, the equipment of upgrading becomes more intelligent, and the information of acquisition is more complete, and the model at this moment describing this equipment just produces
Raw new version, but not armamentarium all upgrade, so will appear a part of equipment is early version, a part of equipment is new
Version.There is new version in data model, and corresponding computation model also has new version, and the logic of calculating will handle different editions pair
The calculation formula of elephant.
Computation model is for handling the calculated relationship of data model, relation belonging to and transmission relationship.When calculated relationship is
Between and spatial granularity change, the plan for example, a daily planning is put into several classes.Relation belonging to is that multiple subobjects have synthesized father
Object, such as a main material data and a part data synthesize a semi-finished product data, this is also to calculate.Transmission is object
Space-time granularity it is constant but position changes, for example raw material data transport from storehouse to line side library, semi-finished product from a work
Sequence is moved to another process, this is that the position of object changes.
The computation model itself also has time model and spatial model essential attribute, it is determined that the space-time of computation model
Attribute, the computation model can only calculate the data model less than or equal to this space-time granularity, and directly according to meter in calculating
The particle size range for calculating model goes to check relevant data model.In addition to title, space-time, version, safe build-in attribute, computation model
Also there are member and channel and calculating logic, the member of computation model is some simple data type, can preserve calculating and use
The last one value because computation model having time and spatial model, computation model and computation model just have set membership, such as
Yearly plan formulates computation model is the father that monthly plan formulates computation model, and father's computation model can direct operator planning model
Member namely sets value to member, and son cannot set value to father.Channel is calculated in addition to that can be that data type can also be data mould
Type, the calculating channel are an array or a data buffer area, and number can be had by calculating to database query of subscription data
It is also transmitted in channel according to transmission data between in channel, calculating and calculating.Calculate channel subsystem channel and self-defined logical
Road, system channel have system message channel, mouse channel, keyboard channel etc., these main processing system asynchronous messages and caching
Graph data.Self-defined channel, which can be the definition of storage model, object definition and object data, a channel, can only select one
Type, our general system operations channel of getting up mainly stores the data for calculating and inquiring.Channel is that computing object reception is asynchronous
The essential component part of data needed for message and calculating.
Father's calculating and setting calculate member, one calculate be another calculate father, then this father calculate the time or
Person space must be the time of sub- calculating or the father in space.Calculate the channel that data transmission can be calculated to another.Meter
Calculate can subscribe to, inquire, connect real-time, history, plan, engineering library data.Wherein in real time, history, plan library are data,
Engineering library is the definition of model, object, and the model in engineering library can only be subscribed to and be inquired cannot connect modification, real time history and
The data in plan library, which can connect modification, can also inquire and subscribe to.The connection of data is equivalent to locking, and the data value of locking is also
It can be accessed but modification cannot be connected by other people, only others, which has changed, produces new versions of data and be disconnected later
The connection third of this data can be attached operation just now.
In system operation, user specifies real-time server, history server, plan server by configuration interface.
Data are issued corresponding server by each server client automatically, such as the reality that real time data client generates this system
When data transmission to real time data server, table can be created on real time data server in real-time data base automatically, and will
In the real-time data base created in related data storage to corresponding real-time server.Historical data base and plan database are also such as
The data acquisition modes gathered data of aforementioned real-time data base.
According to a preferred embodiment, can there are multiple data versions or data type real the same real-time model
The instantiation of existing multiple objects.For example, a workshop is done and upgraded, new legacy system is simultaneously deposited, and new legacy system is the mould used
Two versions of type, space-time database are monitored the system object under the two versions, if some object upgrades, switching
To new version, when historical storage, the corresponding historical record of each version can be stored.Playback to historical data, no
It is only capable of seeing the historical data of each system, and can also check historical upheaval.Such as workshop collection model is V1 versions, is only propped up
Hold two parameters of collecting temperature and humidity.Collection model based on the V1 versions establishes the object in the first workshop, collects
In the value storage to historical data base of temperature and humidity, the version of corresponding model can be also recorded in history library.When running one section
Between after, fielded system upgrading, in addition to wanting collecting temperature and humidity, it is also necessary to pressure is acquired, then collection model upgrades to V2 editions
This, increases the parameter of pressure.After first workshop object upgrading, three collecting temperature, humidity and pressure values are realized in the first workshop,
And in the storage to database of corresponding value.In history library, the history generated in the case of the first workshop different editions will be recorded
Data.

Embodiment 2
It is carried out so that space-time database in process of factory production realizes the modeling for carrying out time and space to creation data as an example
Explanation.Time state and spatiality difference settling time model, spatial model and/or space-time according to each object to be managed
Model.
Time model：Time model is the data model for describing the object time state to be managed.Time model
Time granularity be measure time state unit, including chronomere and be based on the customized time parameter of the condition of production.It is excellent
Choosing, time model is the model for describing the object time granularity to be managed.For example, time granularity be year, month, day, hour,
Minute or second etc..Can also self defined time granularity, such as class or batch.
Spatial model：Spatial model is the data model for describing the object space state to be managed.Spatial model
Spatial granularity be weigh spatial level and spatial position spatial parameter, including mikey and based on the condition of production it is self-defined
Spatial parameter.Preferably, spatial model is the model for describing the object space granularity to be managed.For example, spatial granularity is
Parent company, subsidiary factory, workshop, production line, process, station or equipment etc..
Space-time model is the data model of the spatiality and time state for describing the object to be managed.Space-time mould
Type is a kind of effective organization and management tense spatial data, attribute, the more complete data model of room and time semanteme.When passing through
The time state and spatiality of empty model monitoring object to be managed, can fully understand the operating status of object to be managed.
Data modeling：Description each things be by Model instantiation Lai.For example, product is an object.Product
Processing is something.Product warehouse-out is also something.The product quantity (Employees' achievement) processed on some station is also thing.This hair
It is bright that data modeling is carried out to things based on past, present and following three periods.
Data model is the data used in description system.Data model is divided into real-time, history, plan according to tense.It presses
It is divided into as data, alarm, event according to function.The combination of tense and function has more kinds of data.Data model has version, is
In system, there may be multiple versions for same model.The example of model corresponds to a certain version of model.Model is in life
When at new version, the example generated is not interfered with.When a certain version of model is changed, Model of Version generation can be influenced
Example.
Data model is the model that data are described, and data model consists of two parts：Attribute, member.Attribute is
The distinctive part of data, for example, name, description, time, space, attribute are defined by system, user cannot define.
According to the difference of classification, the attribute of data model has difference, such as real time data, the attribute with freshness.Event data
With attributes such as time started, end time, duration.
Member is the component part for constituting data, and user is can to define different members as needed to come in description business
Data.The data of member can use various types defined above.Consider from performance, membership is limited to maximum
256 members.
Preferably, for attribute-name, member name does not allow more than 64 characters.
The data model specified time model and spatial model of the present invention.The present invention will include time model and spatial mode
The data model of type is referred to as space-time model.For example, the performance model of station processing, space attribute is exactly station, time attribute
It is class.Other attributes of data can be work order number, processing quantity, alarm times, number of doing over again etc..The number of these data models
It is completed according to by computation model, calculates detection creation data variation, timing counts performance data and is output to performance model.
Factory modeling：Model before factory modeling is basis carries out zinc plant engineering.For example, practical factory's title, life
Producing line title, device name, process title, this is space instances.The attached of each object is also determined during instantiation
Category relationship.There are within one day several classes, how long is each class, this is time instance.Actual production line has several process performance datas, this
It is the instantiation of performance data model.Certainly there is the instantiation calculated, because to calculate these performance datas.
System operation：After system operation, system background detects production information automatically, records the condition of production of each process,
The production performance of each station of real-time statistics.So far, just space-time database is recorded in the condition of production of a factory in real time.With
It goes in model of place inquire when family needs to check in real time and historical production data information.
It makes a plan：Making a plan generally can all formulate the such as full factory's yearly plan of total plan, then decompose full factory month, complete
Factory day, class of full factory, workshop month, workshop day, workshop class.As long as user needs that very thin granularity can be decomposed, then often hold
One space-time granularity of row all goes monitoring either with or without executing according to schedule.
According to a preferred embodiment, time attribute and space attribute are independent.Describe have granularity when time object
And precision, for example the granularity in year is year, it can also be millisecond that precision, which can be the second,.Time object meta position sometimes in data record
It sets, at the beginning of time location and the end time.For example 2016 are exactly time location.In March, 2016 is also time location,
3 months general 2016 are 1 day 0 March in 2016 at the beginning of position:00:00.000, the end time is in March, 2016
31 days 23:59:59.999.It preferably, can also self defined time position.For example, with 2016 March in wealth year from customized
Wealth year and the wealth moon, starting and end time are user-defined, such as 15 days 2 days-March of March in 2016, when user uses
2016 March in wealth year meant that this period.
Time model is the model for the granularity for describing the time.For example, dividing time granularity to year, month, day, class, hour, second
Deng.Meanwhile user can also freely define time granularity, such as class, batch etc..Space-time database wants advanced in use
Row data modeling.It will be according to the things or project of monitoring and management carry out the time, space is divided when modeling.For example, by time grain
Degree is divided into year, month, day, class, hour, second.
Spatial granularity is divided into parent company, subsidiary factory, workshop (storehouse), production line, process, station, equipment etc., for example, logical
Spatial object editing machine load Google Maps or Baidu map are crossed, and selection sets corresponding coordinate system in map configuration,
The spatial dimension that a Root root node is drawn based on parent company geographic location, is used in the spatial dimension of Root root nodes
Rectangle/irregular polygon line/point/broken line draws a spatial object to obtain the first order spatial object of parent company.
A spatial object is drawn to obtain the about subsidiary factory with rectangle/irregular polygon line/point/broken line in level spatial object
Secondorder spatial object.In the spatial model of the second level spatial object is drawn with rectangle/irregular polygon line/point/broken line
To obtain the third level spatial object about certain workshop.Because in this approach, realizing to strand space model, which procedure produced
The description of spatial model, station spatial model and device space object.
The data modeling includes being modeled to each things of description.For example, product is an object, product adds
Work is something, and product warehouse-out is also something.The product quantity or Employees' achievement processed on some station are also thing, in space-time
It is to realize to carry out data modeling to aforementioned thing and object in database.Data model includes time model and spatial model.For example, work
The performance model of position processing, the i.e. corresponding space of station, class or shift correspond to the time, and the member of data can be work order number, processing
Quantity, alarm times, number of doing over again etc..The data of the performance model are completed by computation model, that is, pass through calculating
Creation data variation is detected, timing counts performance data and is output to performance model.
It is to carry out zinc plant engineering to building up model when specific to certain factory.By the spatiality of object to be described, with
The corresponding matching of spatial model marks multistage and/or multiple hierachical description object spatial information to realize.For example, specific
Determine practical each division of labor factory title, each production line title, each device name, various processes title, this is space instances.
The affiliation of each object is also determined during instantiation.Specific to determine there are several classes one day, each shift is how long,
As time instance.Actual production line is related to several process performance datas altogether, this is the instantiation of performance data model.Also
Instantiation including calculating will be related to calculating related performance data, include data evaluation work duration, processing number according to acquisition
Amount, alarm times and number of doing over again etc..
After system operation, system background will detect production information automatically, record the condition of production of each process, unite in real time
Count the production performance of each station.So far, just space-time database is recorded in the condition of production of a factory in real time.User needs
It goes in model of place inquire when checking in real time and historical production data information.
Based on space-time database, realization is made a plan, and according to the decomposition of the plan in time and space, issuing for plan also can
It is very easy to.Making the plan generally can all specify the such as full factory's yearly plan of total plan, decompose full factory's monthly plan, full factory day meter
It draws, full factory's shift plan, workshop monthly plan, workshop daily planning, workshop shift plan.User only needs to be intended to be decomposed into very thin
Then granularity completes the monitoring to a time granularity and/or a spatial granularity, you can the global prison for the project that realizes a plan
Control.
For example, user needs to realize the information monitoring to certain factory's boiler.We just need to establish the phase of this boiler
Data model is closed, and establishes matching time and space model, to position or monitor the related data information of boiler.Pass through
Space-time system and data structure are established, time model and spatial model are instantiated respectively, and data model is instantiated as counting
According to object.The data object needs to select some spatial object of the associated spatial model of data model, also to select data mould
Some time object of the associated time model of type is associated.For example, the associated space of boiler Real-time Data Model is boiler
Spatial model, associated time are the time models of class.Boiler spatial model can instantiate out boiler 1, boiler 2, boiler 3, this
A little is all spatial object title.Class's time model meeting example dissolves three mornig shift, the middle class in a kindergarten, night shift objects.Boiler real time data mould
Type instantiates out boiler real time data object 1, his spatial choice boiler 1, and corresponding time acquiescence is a class model.Because being
Real-time objects can only select real-time data base space when computer storage configuration.Similarly realize to historical data base and
The modeling of plan database and association process.Wherein, in modeling process time model foundation, such as the foundation of class's model is
Complete the definition of the period residing for each class, such as the morning time is set as 6 points of morning at 3 points in afternoon.Spatial model
Establish, for example, factory's model and boiler model foundation, be the spatial form to factory's model and boiler model, space profiles and sky
Between position description.Father's model that factory's model is boiler model is defined simultaneously.Data model is established, the data model includes real
When data model, temporal data model and planning data model.When establishing data model, first setting model classification is needed.
After operation, the storage location of data object is determined by types of models：Real-time data base, historical data base, plan database.
Similarly, it is also which library lookup data judged by this type when inquiry.After system operation, real time data object
The value of acquisition is stored in real-time data base, then will be recorded for example comprising temporal information when actually generating data
For morning information on October 21st, 2016, include spatial form, space wheel of the spatial information for 1 corresponding boiler model of boiler
Wide and spatial positional information, including data model corresponds to other such as pots of model classification information and boiler for boiler
