Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The present invention can be used in numerous general or special purpose computingasystem environment or the configuration.For example: multicomputer system, server, network PC, small-size computer, mainframe computer, comprise distributed computing environment of above any system or equipment or the like.
The present invention can describe in the general context of the computer executable instructions of being carried out by computing machine, for example program module.Usually, program module comprises the routine carrying out particular task or realize particular abstract, program, object, assembly, data structure or the like.Also can in distributed computing environment, put into practice the present invention, in these distributed computing environment, by by communication network connected teleprocessing equipment execute the task.In distributed computing environment, program module can be arranged in the local and remote computer-readable storage medium that comprises memory device.
One of core idea of the embodiment of the invention is, a kind of brand-new host computer that is used for the parameters of technique process collection and the mutual framework of slave computer are proposed, in embodiments of the present invention, host computer no longer regularly, remove to control slave computer on one's own initiative and read parameters of technique process, but subscribe to the parameters of technique process that the slave computer of its care is monitored in advance by host computer, in case slave computer detects the ordered parameter of host computer and changes, will the proactive notification host computer, host computer then in view of the above notice need the data of record to be recorded in the database.Thereby make that the collection of parameters of technique process is reasonable more and efficient.
With reference to figure 1, show the process flow diagram of the acquisition method embodiment 1 of a kind of parameters of technique process of the present invention, present embodiment is used to obtain the time dependent situation of parameters of technique process, specifically can may further comprise the steps:
In specific implementation, above-mentioned steps 101 and 102 can realize by making up observer's model.Usually, observer's model is used for defining the dependence of the one to one a kind of or one-to-many between object, and with the state of an object of box lunch when changing, all objects that depend on it all obtain notice and refresh automatically.It can separate observer's object with observed person's object fully, is independently safeguarding one to the interested dependence of main body (observer's object) tabulation in the object (main body).Allow all observer's objects realize public Observer interface separately, with the direct dependence between cancellation main body and the dependence object.
Give an example, user interface can be used as observer's object, and business datum is observed person's object, and the variation of user interface observed traffic data after the discovery data variation, just is presented on the interface.Basically, observer's model must comprise two roles: observer and observed object.In this example, business datum is observed object, and user interface is the observer.The logic association that has " observation " between observer and the observed person, when the observed person changed, the observer will observe such variation, and made corresponding response.If between user interface, business datum, use such observation process, can guarantee to draw distinction in accordance with between interface and the data, suppose that the demand of application program changes, need to revise the performance at interface, only need rebuild a user interface, business datum does not need to change.As seen, observer's model can have been delimited boundary clearly between module, thereby improve the maintainability and the reusability of application program.
In practice, making up observer's model has a lot of modes, in a preferred embodiment of the present invention, shows following building mode, specifically can comprise following substep:
Substep A1, set up observer's model, in this model, host computer is maintained as observer's object Observer, the parameters of technique process of its subscription is maintained as observed person's object Subject; Wherein, described observer's object will oneself be registered in the observed object, and observed object leaves observer's object in the container C ontainer in;
Substep A2, when observed object changes, from described container, obtain observer's object of described registration, and with change notification observer object.
Observer's object is when oneself being registered in the container of observed person's object, and observed person's object is kept aloof from the particular type of observer's object, and is to use the interface of observer's object.The advantage of doing like this is: also have other observer's object in the supposition program, so as long as this observer's object also adopts identical interface to realize.Observed person's object can corresponding a plurality of observer's objects, and when observed person's object changed, it can be notified to message all observer's objects one by one.This point can also further provide greater flexibility for program.
Certainly, only as example, those skilled in the art select for use arbitrarily according to experience or actual conditions and get final product the building mode of above-mentioned observer's model, and the present invention need not this to be limited.
Be well known that, at industrial control field, host computer is the effector, slave computer is Be Controlled person, the mutual framework of host computer and slave computer generally is that host computer sends instruction to slave computer, slave computer is directly controlled corresponding process equipment according to this instruction again, and the status data of fetch equipment also feeds back to host computer.In brief, host computer and slave computer can be understood as the relation of main frame and slave.
Based on this generally acknowledged host computer and the mutual framework of slave computer, those skilled in the art are when improving data acquisition function, normally pass through in the time interval of host computer adjustment from the slave computer reading of data, or other application program is set in host computer or increases other and instruct and consider, for example, for parameter comparatively stable in the technological process, the data read interval (as 300ms/ time) of long period then is set in host computer, for changing bigger parameter in the technological process, the data read interval (as 100ms/ time) of short period then is set in host computer, be that its essential framework is still host computer and regularly notifies the slave computer reading of data, slave computer is again to the host computer feedback data then.Moreover, because host computer is used for the user directly mutual (as accepting user's request, output file, displaying parameters of technique process etc.) in concrete the application, slave computer links to each other with each process equipment respectively, be used to monitor each process equipment, so this basic host computer and the mutual framework of slave computer are the basic software frameworks that the technician generally admits at industrial control field, and can not go to consider to adopt other software architecture to improve the possibility of data acquisition function.
Yet, the root problem of the existence of a large amount of junk datas when the inventor herein has noticed data acquisition, creatively propose a kind of brand-new host computer and the mutual framework of slave computer and solved this problem, be that slave computer is not that passive wait host computer is controlled, but when satisfying predefined condition (when the ordered parameters of technique process of host computer changes), the proactive notification host computer, and relevant data are fed back to host computer, host computer is directly preserved required data and is got final product.Be that the present invention has overcome the technology prejudice that those skilled in the art must make improvements based on the basic mutual framework of host computer and slave computer, and directly the mutual framework of host computer and slave computer is changed, and need not change or additionally increase hardware, just effectively reduce the collection of junk data, guaranteed the validity of institute's image data.
With reference to figure 2, show the process flow diagram of the acquisition method embodiment 2 of a kind of parameters of technique process of the present invention, present embodiment is used to obtain the time dependent situation of parameters of technique process, specifically can may further comprise the steps:
Step 201, when the parameters of technique process of subscribing in advance to host computer when the next machine testing changes, the notice host computer;
Step 202, described host computer obtain described parameters of technique process and time information corresponding according to this notice, and are stored in the database;
The parameters of technique process and the time information corresponding of meeting consumers' demand in step 203, the described database of extraction generate the output table.
Present embodiment and difference embodiment illustrated in fig. 1 are that present embodiment has increased is convenient to the step 203 that the user checks and analyzes the parameters of technique process of being gathered.
Regularly notify in the scheme of slave computer reading of data at existing host computer, the design of host computer database is to safeguard two tables, a table (technology recording mechanism table) is used for the recording mechanism ID of service procedure, the zero-time starttime and the concluding time Endtime of technology, and a table (parameter value record sheet) is used for the time point and the corresponding parameters of technique process value of maintenance record.In the prior art, need the number of parameters of record not wait from several to dozens of.
For example, using the database storing mode of prior art, is 5 at the current recording parameters that needs, and is respectively ParamA, ParamB, and ParamC, ParamD, during ParamE, then corresponding record is as shown in the table:
Wherein, being recorded as at technology recording mechanism table:
| ??ID | ??starttime | ??Endtime |
| ??78 | ??2009-7-2?09:26:27.000 | ??2009-7-2?09:26:28.000 |
Being recorded as of parameter value record sheet
| ??Time | ??ParamA | ??ParamB | ??ParamC | ??ParamD | ??ParamE |
| ??2009-7-2?09:26:27.000 | ??100.33 | ??999.35 | ??50 | ??156 | ??500.02 |
| ??2009-7-2?09:26:27.200 | ??99.88 | ??999.55 | ??50 | ??156 | ??500.02 |
| ??2009-7-2?09:26:27.400 | ??98.45 | ??1000.69 | ??50 | ??156 | ??500.02 |
| ??2009-7-2?09:26:27.600 | ??101.87 | ??1000.78 | ??52 | ??156 | ??499.68 |
| ??2009-7-2?09:26:27.800 | ??100.25 | ??1005.82 | ??49 | ??156 | ??499.85 |
| ??2009-7-2?09:26:28.000 | ??100.97 | ??1000.58 | ??49 | ??157 | ??499.26 |
Be that the related data that slave computer reads is to be stored in the database in top mode.Operating personnel check and analyze data for convenience, and application program can be read data from database, are placed on the buffer memory the inside then, data are write in the excel file line by line again, and the last operation personnel can check and analyze these data by excel.
Can find more intuitively from above-mentioned two forms, adopt prior art to write down a large amount of repetitions, useless data (junk data) inevitably, as parameter ParamC, variation has only taken place when 2009-7-209:26:27.600,2009-7-2 09:26:27.800, can be owing to host computer is to notify the next machine-readable data every 200ms, so in database, also write down the data of redundant 2009-7-2 09:26:27.200,2009-7-2 09:26:27.400, three time points of 2009-7-2 09:26:28.000.
In a preferred embodiment of the present invention, the design of host computer database can be safeguarded two tables equally, one of them table (technology recording mechanism table) is same as the prior art, be used for the recording mechanism ID of service procedure, the zero-time starttime and the concluding time Endtime of technology, another table (parameter value record sheet) is used at each parameters of technique process recording process zero-time, changes time of origin, and, the parameter value of corresponding time point.Promptly in embodiments of the present invention, each parameter value record sheet only needs the related data of a parameters of technique process, the parameter value of technology zero-time and corresponding time point, it is the benchmark of judging whether parameter changes, so need be recorded in this table, change time point and the corresponding parameters value that takes place but then only write down afterwards.
For example, using database storing mode of the present invention, is 1 at the current recording parameters that needs, and promptly during ParamC, then corresponding record is as shown in the table:
Wherein, being recorded as at technology recording mechanism table:
| ??ID | ??starttime | ??Endtime |
| ??78 | ??2009-7-2?09:26:27.000 | ??2009-7-2?09:26:28.000 |
Being recorded as of parameter value record sheet
| ??Time | ??ParamC |
| ??2009-7-2?09:26:27.000 | ??50 |
| ??2009-7-2?09:26:27.600 | ??52 |
| ??2009-7-2?09:26:27.800 | ??49 |
Or as, use database storing mode of the present invention, be ParamC in the current record parameter, slave computer also detects it and has taken place once to change when 2009-7-2 09:26:27.500, and then corresponding record is as shown in the table:
| ??Time | ??ParamC |
| ??2009-7-2?09:26:27.000 | ??50 |
| ??2009-7-2?09:26:27.500 | ??51 |
| ??2009-7-2?09:26:27.600 | ??52 |
| ??2009-7-2?09:26:27.800 | ??49 |
From above-mentioned example, can intuitively reflect the collection of the minimizing junk data that the present invention can obtain, the validity of assurance data acquisition, and save the beneficial effect of system resource.

Parameters of technique process and time information corresponding that substep B1, extraction are met consumers' demand are deposited to temporary table;
Substep B2, the data in the described temporary table are exported as the excel file.
Promptly in specific implementation, application program can be not directly from the database of host computer reading of data generate the excel file then, but in database, write a storing process, generate the excel file by calling this storing process.Particularly, storing process be exactly demand according to the user data scattered in the database, derive in a temporary table, the structure of temporary table is the same with the structure of the excel table that the user finally sees, only is present in the table in the database.And then, derive and generate an excel file the data in the temporary table.For example, generate the excel file of the reference record of certain interval of time, perhaps, if the excel file that has a parameter to change and just generate a record, to have reacted the actual conditions of production process equipment more truly.
Certainly, described output table also can be the data list file of other form, and the present invention need not this to be limited.Need to prove, for aforesaid each method embodiment, for simple description, so it all is expressed as a series of combination of actions, but those skilled in the art should know, the present invention is not subjected to the restriction of described sequence of movement, because according to the present invention, some step can adopt other orders or carry out simultaneously.Secondly, those skilled in the art also should know, the embodiment described in the instructions all belongs to preferred embodiment, and related action and module might not be that the present invention is necessary.
