Hereinafter just the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to reason
Solution, grasp.
Specific embodiment
Present invention is disclosed a kind of photovoltaic module power method of testing, it is characterised in that comprise the following steps：
S1, makes series of standards piece；
S2, sets up data base according to the information of each standard film in S1；
The data base set up in S2 is included tester software system, is had access to for test interface by S3；
S4, chooses the standard film for meeting test request from tester software system；
S5, with the standard film calibration tester chosen in S4；
S6, treats survey photovoltaic module and is tested with the tester after S5 alignments.
Tester software system described in S3 is MES system.MES system is that manufacturing enterprise's production process performs management system
System, is the production information management system of a set of Manufacture Enterprise workshop execution level.Substantially, operation of the invention is also base
In the MES system.
Data base described in S2 comprising the standard film electrical parameter information, suitable for the model of photovoltaic module to be detected
The EL test result informations of information, pot life information and each standard film.
The electrical parameter information is one group of test result that third party's laboratory is given under standard test condition, including
Power, open-circuit voltage, short circuit current, maximum working voltage, maximum operating currenbt, fill factor, curve factor.Every piece of standard film has and only has
One group of electrical parameter, the electrical parameter are to contrast automatically each tester calibration whether qualified sole criterion using MES.
MES be capable of achieving using the calibration range that each company oneself defines contrast automatically each target to test whether in the range of and every
Whether secondary calibration is qualified.General processing enterprise carrys out calibration tester using power or short circuit current, and the scope calibrated respectively has
Difference, such as Pmax ± 0.2W, Pmax ± 0.1%, Isc ± 0.3A etc..And controlled when tester calibration is unqualified by MES system,
Component can not be tested.It should be noted that not tester of can not testing herein is unable to test suite, but whole test is flowed
Cheng Buneng is covered, and the module information after such as testing can not enter MES system, so as to reach fool proof effect.
After every piece of standard film calibration tester, tester can only test component corresponding with current standard film model, model
Mainly include mono-crystal component, polycrystalline component, 60 components, 72 components, solar double-glass assemblies etc..MES system passes through this of standard film
Partial information can test the component of which kind of model judging current calibrated tester.Herein it should be added that, on
The premise for stating step is to need the operator must be by component model Data Enter MES so as to match with standard film model, Jin Erda
To the purpose for preventing standard film to be suitable for mistake.
Pot life information is automatically reminded to and expired unusable management to realize that standard film is expired.It is wherein automatic
Remind and associated mail can be sent automatically to corresponding personnel by MES, and expired unusable be accomplished by directly in test interface what is said or talked about
Go out dialog box teaching process person this standard film out of date unusable.
The EL test result informations of the standard film are to be related to the whether available another key factor of the standard film, this
Part needs EL testers after the EL for having tested standard film every time by test result typing MES system, so as to by MES systems
System automatically controls whether standard film can use.
Test interface described in S3 include next time calibration count down information, can use standard film information, at present can test light
Volt component type information.This part is exactly that partial information above-mentioned is shown in the test interface of MES system in fact, just
Observe in employee.It is specifically as follows：
Next time calibration count down information be to ensure that operator fully according to documentation requirements frequency go monitor tester such as per 2
A hour tester of calibration.Certainly a foolproof function, i.e. countdown certain hour can also be increased here also not weighing
The component of new calibration tester so follow-up test can not typing MES system.
The mark of which numbering can should be used using the order or component that standard film information is operator's inquiry production at present
Quasi- piece.Just prompting should be using the standard of which numbering automatically for the relevant information of operation this order of employee's typing or component to be tested
Piece.
Photovoltaic assembly type information can be tested at present refer to tested standard film in operator or calibration is good tests
After instrument, this interface needs to show the testable component model of current tester, and it is current to be tested to facilitate operator to compare
Whether component is corresponding with standard film.Along with foolproof function ensures that the component for mismatching model with standard film can not be tested.
In addition, in addition it is also necessary to supplement, the Data Enter of the test interface is needed to prevent the artificial typing of employee from slipping up
It is set to only barcode scanner to sweep, Pasting and is not manually entered.
S4 comprises the steps：
S41, the standard film matched with model photovoltaic module to be measured according to the model of photovoltaic module to be measured, selection；
S42, the electrical parameter information of standard film selected by extraction are simultaneously judged, into next step if qualified, if unqualified,
Then system alarm；
S43, extract selected by the pot life information of standard film simultaneously judged, jump into next step if qualified, if unqualified,
Then system alarm；
S44, extract selected by the EL test result informations of standard film simultaneously judged, jump into S5 if qualified, if unqualified,
System alarm；
In S6, treating survey photovoltaic module using the tester after calibration carries out comparing analysis, if qualified, into next work
Sequence, if unqualified, system alarm.
The photovoltaic module power method of testing of the present invention can realize the intelligent management to standard film, reduce and even prevent
The standard film that artificial operation is easily caused is using the problems such as error.Simultaneously as the method for testing of the present invention reduces artificial behaviour
Make the participation in whole test process, not only improve the accuracy of whole test process to a certain extent, also shorten
Time of whole power test, improve testing efficiency.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of spirit and essential characteristics without departing substantially from the present invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
