Embodiment
In embodiments of the present invention, judge whether to exist in supervisory system and export corresponding point with functional block, do not exist when to export corresponding point with functional block, increase according to mapping method and export corresponding point with described functional block, and calculate, by result of calculation stored in exporting with described functional block in corresponding point in supervisory system according to the input value of functional block, parameter and historical data etc.; Exist when exporting corresponding point with functional block, calculate according to the input value of functional block, parameter and historical data etc., result of calculation is exported in corresponding point with described functional block stored in supervisory system.
The vertex type of the real-time database of different Industry Control configuration monitoring systems is not identical, and some systems only have fundamental point type, does not have extension point type; The existing fundamental point type of some systems, also has extension point type.Each functional block may have one or more output, each output should in supervisory system a corresponding point.Therefore need to set up mapping relations by between the output of functional block and the point of supervisory system.Mapping method comprises: drive the name of the coding of type and point to map according to the type put, I/O.Be specially: each functional block comprises at least one output valve, a point in the corresponding supervisory system of each output valve.Here, the information such as the attribute of each functional block, algorithm and output valve are stored in described functional block; The point of described supervisory system is used for depositing the information such as instantaneous value, so that picture exhibition and operation etc.This picture exhibition and operating process are realized by other supporting programs.
In the embodiment of the present invention, setting up the method mapped is: the output of functional block is corresponding with the point of supervisory system.Such as, the n of a functional block output valve is corresponding with n point of supervisory system.
Here, described Industry Control configuration monitoring system includes but not limited to iFix system, Citect, Wonderware and RSView system; Output due to a functional block is often multiple output valve, and each point of iFix system, Wonderware system, RSView system and Citect system only has an output, for iFix system, need mutually corresponding for n the output valve put of the n of a functional block output valve and iFix system, as: the XY_MQ_1 of functional block and the corresponding iFix system of suffix XY_MQ.Value1 thereof, the XY_MQ_D3 of the corresponding iFix system of XY_MQ.DValue3, the output valve of concrete functional block and the output valve corresponding relation of iFix system point as shown in table 1.
| The suffix title that functional block exports | Numbering |
| Process system | Nothing |
| Domain name Value | Nothing |
| DValue1,DValue2,DValue3,DValue4,DValue5 | _D1,_D2,_D3,_D4,_D5 |
| Value1,Value2,…,Value50 | _1,_2,…,_50 |
Table 1
Above-mentioned mapping method specifically comprises the work such as the type determined a little, the coding name determining I/O driving type and point, the order not restriction of these work, and these work can determine according to the type of supervisory system in advance, or realized by human configuration, or carry out judgement by computer program and determine.Be described concrete mapping method respectively below.
First the type of the point how determining supervisory system is introduced.
The point of the different supervisory system of each supervisory system producer has different types, and analog quantity adopts analog quantity register point, and switching value adopts switching value register point, and character string quantity adopts character string point; In iFix system, specific as follows: when analog quantity adopts analog quantity register point AR(inadequate, to use analog quantity alarm set point AA), use switching value alarm set point DA when switching value adopts switching value register point DR(inadequate), character string adopts text point TX; " process coding and sequence number " aspect Optimum Points in encoding of calling the roll adopts coding " Y ".
Consider that the different system such as iFix system, Citect, Wonderware and RSView all has analog quantity point, switching value point and character string point, the producer that the point of other types then has has, and some producers do not have; In addition, the sum of iFix system point is limited, as: the summation of all drivings of AI can not more than 32767 points, and Industry Control configuration monitoring system often uses analog input point AI/ analog quantity alarm set point AA/ On-off signal point DI/ switching value alarm set point DA; And the register point of iFix system does not have scanning switch, take resource relatively little.Therefore in iFix system, adopting a little type as follows: analog quantity adopts analog quantity register point AR, uses analog quantity alarm set point AA when quantity is inadequate; Switching value adopts switching value register point DR, uses switching value alarm set point DA when quantity is inadequate, because character string site monitoring system uses seldom, so, optimize character string point and also adopt text point TX type.
In Wonderware system, analog quantity point adopts Memory Real type, and switching value point adopts Memory Discrete type, and character string adopts Memory Message type; In Citect system, analog quantity point adopts Real type, and switching value point adopts Digital type, and character string adopts String type; In RSView system, analog quantity point adopts the Real type of analog quantity, and switching value point adopts switching value type, and character string adopts character string type.
According to different monitoring system, determine whether to need to select I/O to drive, and select which kind of I/O to drive, and add point to Industry Control configuration monitoring system and upgrade real-time database.
In iFix system, iFix system provides three I/O and drives: OPC drives, Simulation drive SIM and Simulation drive SIM2; Can not add a little because OPC drives, only have and use Simulation drive SIM and SIM2, third party's program just can be made result of calculation to be stored in the real-time database of iFix system: PDB database, and SIM only provides 2000 analog quantitys and digital quantity register, than SIM2 provide 20,000 analog quantitys and digital quantity register few a lot, add the register number of optimization calculation requirement more than 2,000, so select SIM2 to drive.
In Wonderware system, do not need to select to drive; In Citect system, point all defines in signature, drives the general protocol selecting Citect: GENERIC; In RSView system, the data source of point all selects internal memory.
Point is encoded, coding " Y " is adopted to " process coding and the sequence number " in point; When functional block item is named, because each supervisory systems such as iFix system require that functional block item title can not have identical title, therefore for preventing item Name Conflict, following Naming conventions has been formulated: regional code+process coding and sequence number+" _ "+purposes coding+other+suffix.Regional code is relevant with the geographic position in region, and different regions adopts different codings, with the Naming conventions of avoiding a conflict and the coding relevant to region.
Default value instead of full name can be adopted, by the suffix of the EDA interface judging point of iFix system during operation, to determine vertex type to the point belonging to iFix system.As only inputted item title containing suffix, be analog quantity or switching value by the EDA interface judging point of iFix system during as run, then suffix " F_CV " by name, as character string then suffix be called " A_CV ".Be called with air compressor machine electric current item: KongYaJi, picture associates its current value to be needed to input " KongYaJi.F_CV ", and only needs when inputting to input " KongYaJi ", and unnecessary input " KongYaJi.F_CV ".Whether existed by the suffix of OPC interface judging point and point.If fruit dot is then character string point TX without " F_CV ", otherwise be numerical quantities point AA/AI/AR/DA/DI/DR, because the existing F_CV of numerical quantities point also has A_CV.Suffix as F_CV and A_CV two points does not exist, then there is not this point in iFix system.
In Wonderware system and Citect system, owing to only having instantaneous value in opc server dot information, there is no the information such as description a little, so do not need suffix, just there is not default value yet.
Below in conjunction with drawings and the specific embodiments, the enforcement of technical solution of the present invention is described in further detail.Fig. 1 is the optimization method schematic flow sheet of the embodiment of the present invention one energy management and control, and as shown in Figure 1, the optimization method of embodiment of the present invention energy management and control, comprises the following steps:

Described Industry Control configuration monitoring system includes but not limited to: for iFix system, Citect, Wonderware and RSView system of Industry Control configuration monitoring.
Described mapping method comprises: drive the name of the coding of type and point to map according to the type put, I/O.Point corresponding with the output of functional block in described supervisory system, is specially: each functional block comprises at least one output valve, a point in the corresponding supervisory system of each output valve.
Concrete, in operation start-up course, functional block is exported corresponding point and automatically adds or be updated in Industry Control configuration monitoring system.Obtain real time data and/or historical data from supervisory system, according to the real time data of described acquisition and the configuration configuration information of historical data and functional block, carry out computing, and by operation result stored in described supervisory system.
Wherein, in start-up course for add some points in supervisory system and initialized process, specific as follows:
By the api interface of Industry Control configuration monitoring system, whether arbitration functions block exports corresponding point exists in Industry Control configuration monitoring system, if there is no, then put to the interpolation of Industry Control configuration monitoring system and describe the bound of described point, otherwise, the type of acquisition point, the point of supervisory system described in initialization.
Start-up course specifically comprises a series of process.Fig. 5 is an embodiment of start-up course of the present invention, comprising:
Step 203a: initialization procedure;
Such as in iFix system, relation storehouse, Industry Control configuration monitoring system real-time database, history library data and configuration information is obtained by the configuration information reading configuration file Config.ini, then read the functional block allocation list information in relation storehouse according to functional block allocation list title, then connect opc server and the real time history storehouse of Industry Control configuration monitoring system.Initialization success, then perform 203b, otherwise this flow process terminates.
Connect because a functional block allocation list needs to take an OPC, the restriction that the OPC number of connection solving iFix system by the way that multiple functional block allocation list is merged into is authorized, 1 server of current iFix system only supports the connection of 10 OPC clients.Configuration software obtains each functional block allocation list title according to configuration file, and then obtains each functional block allocation list information and carry out graphical representation and editor.
Step 203b: according to each functional block of content instanceization obtained;
Step 203c: the Correctness checking carrying out functional block item information;
Step 203d: the correlativity of searching each functional block input pin, determines that data source is that real-time database or program are inner;
Step 203e: according to its relevant information in real-time database of result item name acquiring of functional block, then adds corresponding point automatically as result functional block item does not exist in a database;
When need in supervisory system to increase exports corresponding point with functional block time, what need to judge described supervisory system adds dotted state, if not idle condition, then wait is until the free time; If idle condition, then add some points, and the dotted state that adds of described supervisory system is changed into not idle.
Be specially: call api interface or OPC interface, export the description of corresponding point with functional block described in obtaining from described supervisory system and be updated in the configuration information table of described functional block.
The point of Industry Control configuration monitoring system obtains its suffix/OPC handle.Because appointment function agllutination fruit leaves Industry Control configuration monitoring system real-time database in, as the real-time database of iFix system, if there is not the point identical with result name in this database, so according to the Name and Description of the stored table of functional block acquiescence, call the interface of real-time database, automatic powder adding is added some points.And then obtain this relevant information in real-time database, so that operating software obtains the instantaneous value of real-time database.
Do not contain the system of the descriptor of point for opc server, call the description of api interface from Industry Control configuration monitoring system acquisition point; Otherwise call OPC interface obtains input point description from the opc server of iFix system.First needing to obtain item whether to exist at opc server, whether successfully judging whether there is this point in opc server by adding OPC Item, as having this point in success then database, otherwise not having.This scheme than once searching for all points of OPC, then contrasts whether to there is speed a lot of soon successively.
Check in Industry Control supervisory system whether have corresponding point, then do not add, concrete: by the api interface of Industry Control configuration monitoring system, whether acquisition point exists in Industry Control configuration monitoring system, as fruit dot does not exist, then add to Industry Control configuration monitoring system and put and describe its bound, otherwise, the type of acquisition point, point described in initialization.For iFix system, namely by api interface and the EDA interface of iFix system, whether acquisition point exists in iFix system, do not exist and then add point, description and bound thereof etc. to iFix system, exist, the type of acquisition point is analog quantity register point, switching value register point or character string point etc.
Step 203f: the compute depth determining each functional block;
Step 203g: obtain historical data to each functional block;
According to " IN_HIS_COUNT " field contents of functional block configuration information table, just can know that this functional block needs the time span of historical data, calling interface, as OLE DB history interface obtains historical data.
Step 203h: by each functional block initialization, and check;
Step 203i: insert/upgrade functional block structural information table and functional block allocation list, upgrades the description of real-time database point;
Inserting/upgrade functional block structural information table makes the configuration stage can know the information such as the number of each functional block input/parameter/output and description thereof.Upgrading functional block allocation list, from Industry Control configuration monitoring system, as obtained the description of input point in iFix system, being then updated to functional block allocation list, so that configuration display.And the description that namely functional block result item is put is updated to the real-time database of iFix system.
Step 203j: this flow process terminates.
To the system of the necessary configuration address of point, as iFix system and Citect system, the multiprogram for being distributed in different server is needed to drive the Process Design adding point to lock and unlocking mechanism to optimum results point, to prevent the address of adding different optimum results identical, configuration address is not needed for Wonderware system point, does not then need this step.Lock information leaves in the lock information table in relation storehouse, name is called " PUB_LOCKTABLE_GE ", only deposit relevant information of adding some points, this table only has a line, and the information of depositing has: the minimum available address of the minimum available address of current relation storehouse lock status, present day analog amount point, the minimum available address of current switch amount point and current string point.First reading current relation storehouse lock status time program is added some points, is that 0 expression does not lock, and does not namely have program to add some points to iFix system automatic powder adding at present; 1 expression locks, and represents and has program to add point to iFix system at present.When program finds that relation storehouse lock status is 0 time, lock, then add point according to minimum available address, after adding point, increase the address of minimum available point; Deng institute a little all adds after, carry out unlock while the address of the current minimum available point of all types of point is updated in the lock information table in relation storehouse.If find that current relation storehouse lock is locking state, then wait for, if wait for that number of times is more than 100 times, then show to have waited for 25 minutes, may occur deadlock, the side-play amount of acquisition is all increased certain value to reduce conflict as far as possible, compulsive unlocking after terminating of adding some points.
Detailed adds unlocked step as shown in Figure 6, and Fig. 6 is that embodiment of the present invention iFix system adds locking and unlocking flow process of point, comprises the following steps:
Steps A: current iFix system add some points lock assignment be 0; Counter assignment is 0;
Step B: judge whether all functions block scan terminates; When the end of scan, perform step I; Otherwise, perform step C;
