Thus, according to the invention, bad influences caused by the manual misoperation can be avoided in the test process, and the execution efficiency of the whole production flow is improved.
Description
Technical field
The present invention relates to the communications field, particularly a kind of Apparatus and system that is used for base station testing.
Background technology
At present, the production process of the base station product among the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD SDMA) comprises: the making sheet process, mount process, single-board testing, final assembly, the test of Base Band Unit host function, the calibration of Remote Radio Unit main frame and a series of links such as functional test, Remote Radio Unit main frame burn-in test and system testing.Each link all has inseparable getting in touch with the link of its front and back, so the quality that previous link is finished will directly have influence on the implementation effect of next link.For example, because producers' carelessness, the single-board testing link not after tested the integrated circuit board or the integrated circuit board of test crash directly be assembled to and flow into the system test link in the complete machine again, need open cabinet after in system test, pinpointing the problems and carry out fault location, again the fault integrated circuit board is back in the preceding road production process and keep in repair again and test.In the batch production process of up to ten thousand equipment, analogue will take place inevitably.If do not supervised and control, this problem will badly influence production efficiency.
In view of this, provide following two kinds of solutions under the prior art:
A, by producers' hand filling flow process folk prescription formula
Adopt this mode, each base station equipment of producing can subsidiary a production procedure be controlled single in the whole production flow process, producers fill in according to the requirement on it after finishing this post work, and the operating personnel in next post will instruct operation according to the record on the flow process list.Detect or inspect by random samples by the quality personnel at last.
Yet, adopt option A, there is following problem:
(1) producers are pre-job must carry out a large amount of trainings to it, grasps for the single filling method of flow process control to make it.In case some execution link changes in process of production, must carry out secondary even repeatedly training to producers;
(2) flow process control singly all will be along with product be transmitted, is filled in, is revised in the whole production flow process, and therefore problem such as will occur wearing and tearing, lose inevitably.And in a single day above-mentioned condition appears, the current state of product can't be reviewed;
(3), there are differences for the statement the possibility of result of same problem because producers' quality difference; And the mode of hand filling may be beyond recognition owing to the individual persons careless handwriting makes other people.Bring unnecessary trouble below all can for the operation in follow-up post;
(4) because whole process is single all by filling in by hand, the result is clear inadequately, is not easy to the quality personnel and carries out the final detection of dispatching from the factory;
(5) owing to be manual work, can't guarantee can occur the problem that individual persons is faked in implementation process, for example find in the product test that a certain index is defective, Direct Mark is passed through on flow process is single, causes underproof product to flow into the outfield.
B, the control of flow process label
Adopt this mode, can prepare some labels at each production station in advance, these labels will be contained all known case, as test event, failure cause etc., producers can be attached on the assigned address of integrated circuit board or cabinet according to the label of actual test result with correspondence, and follow-up post will be carried out operation on this basis.Detect or inspect by random samples by the quality personnel at last.
The scheme b scheme a that compares has some improvement, but still has following problem:
(1) reduced pre-job training, but when carrying out link generation change, flow process control personnel need revise involved label, and still must give training producers producers;
(2) flow process still exists in the whole production flow process and to be transmitted, to fill in, revise, and then appearance such as weares and teares, loses at problem;
(3) misunderstanding that causes because of the difference that execution result is described can not appear;
(4) be convenient to the quality personnel and carry out the final detection of dispatching from the factory;
(5) same because manual work can't guarantee can occur the problem that individual persons is faked in implementation process.
In sum, the production test flow process of existing base station equipment can be because such scheme a and scheme b in the base station equipment large-scale production process, be easy to have influence on because of the error that occurs on the single flow process efficient of whole production flow process.

Embodiment
Avoid in testing process, influencing the execution efficient of whole production flow process, the invention provides a kind of base station testing Apparatus and system owing to operate miss.In the practical application, should dispose at least two testing apparatuss in the base station testing system, consult shown in Figure 1, in the present embodiment, to dispose five testing apparatuss is that example describes, this five station server is respectively applied for base station equipment is carried out single-board testing, functional test before complete machine is aging, burn-in test, aging back functional test of complete machine and system testing, be called five test posies, base station equipment is every through a test post on the test streamline, corresponding testing device just reads the test data that has write from tested base station equipment, and determine that according to the test data that reads base station equipment is not after tested or during the test by a last testing apparatus, this base station equipment is carried out the test in current post, and generate corresponding test data, and the test data that generates is write base station equipment according to test result.
Further, testing apparatus can also be preserved the test data that reads, and the test data that generates according to test result is preserved; And the test data of preserving is presented, and report to background server, or/and, the bookkeeping indication that background server issues received.
Wherein, testing apparatus is worked as Pretesting to described base station equipment, if when determining described base station equipment by test according to test result, then directly generate and be used for the test data that characterization test passes through, if when determining described base station equipment not by test according to test result, to not carry out step-by-step by test items corresponding parameters value and be used for the unsanctioned test data of characterization test with the generation of operation back, this point will describe in detail in subsequent embodiment.
In the present embodiment, so-called base station equipment can be the single part equipment that is used to be assembled into the base station, as, veneer, also can be the whole set equipment after assembling is finished, and sees the tested object in each test post and decides, and does not repeat them here.
Consulting shown in Figure 2ly, is example with any testing apparatus, should comprise I/O control unit 200 and test cell 201 in the testing apparatus at least, wherein
I/O processing unit 200 is used for the test data that write from reading of tested base station equipment, and with the test data that this testing apparatus generates write described in;
Preferable, in the present embodiment, the interface that I/O processing unit 200 externally provides by base station equipment (as network interface, serial ports etc.) is read, is write the idle address in its memory (as E2PROM, flash etc.) or operation such as modification, distinguish or the different in process of production state of judgement base station equipment, to reach the purpose of it being carried out the automatic flow monitoring.
As shown in Figure 2, further can comprise memory cell 202 in the testing apparatus, be connected with test cell 201, be used to preserve the test data that the I/O processing unit reads with I/O processing unit 200, and the test data of described test cell generation.
So-called test data promptly can be to be used for flow process control label, also can be the fault label, and the implication of these two kinds of labels will describe in detail in subsequent embodiment.
In the present embodiment, the test data that testing apparatus reads from base station equipment and writes to base station equipment, it is the label that the test cell 201 in the testing apparatus is provided with in the memory of tested base station equipment by the I/O processing unit, be divided into two kinds, be called flow process control label and faulty tag.For example, in E2PROM, test cell 201 is chosen the memory address of 0xAF address as flow process control label, chooses the memory address of 0xBF address as faulty tag, and its value by default all is 0xFF.
At first, introduce flow process control label.Consult shown in the table 1, all there is the value of flow process control label corresponding behind the correct execution test operation in each test post.
For example, the test cell 201 of testing apparatus that is used for carrying out single-board testing is before carrying out test, whether the value that reads the 0xAF address in the memory of base station equipment earlier is 0xFF, if, base station equipment then is described not after tested, then it is begun to carry out single-board testing, and in successful execution behind the single-board testing, the value 0xFE that is used to represent to test successful flow process control label of correspondence is write the 0xAF address of base station equipment as test data, otherwise.The expression base station equipment will be reprocessed and be tested again not by being worked as Pretesting; Equally, be used for carrying out complete machine aging before the test cell 201 of testing apparatus of functional test before carrying out test, whether the value that reads the 0xAF address in the memory of base station equipment earlier is 0xFE, if, illustrate that then base station equipment passed through single-board testing, then, begin to carry out the aging preceding functional test of complete machine, and in successful execution complete machine aging before after the functional test, the value 0xFC that is used to represent to test successful flow process control label of correspondence is write the 0xAF address of complete machine as test data, otherwise, illustrate that base station equipment is not by the aging preceding functional test of complete machine, this base station equipment will be carried out fault location, maintenance ..., and analogize, carry out the complete machine burn-in test subsequently successively, aging back functional test of complete machine and system testing, the value of writing of flow process control label can not be referring to table 1 in each test link, be after test data that the test cell 201 in the testing apparatus that uses in link of each test all writes down according to base station equipment 0xAF address determines that previous step is tested successfully, carry out the test in current post again, and after the successful execution test, the test data that record is new in the 0xAF address is used for test next time.
Table 1
Secondly, introduce faulty tag.The value of corresponding faulty tag behind each all wrong execution test operation in test post.If the test operation failure, then flow process control label can not be modified, but according to by test items corresponding parameters value faulty tag not being rewritten.
For example, consult shown in the table 2, with the single-board testing is example, and single-board testing has five test events, is respectively transmitting gain (TxGain) receiving gain (RxGain), Adjacent Channel Leakage Power Ratio (ACPR), error vector magnitude (EVM) and receiving sensitivity (RSL).Whether passing through by specifying bit to mark (bit position of band underscore in the table 2) of each test event, as shown in table 2,1 expression is passed through, 0 expression failure.Remaining 3bit (3 of highest order bits in the table 2) uses when giving in the future the extend testing project in advance, if all test is passed through, keep default value constant in the 0xBF address of the memory of base station equipment, do not pass through project if there is test, then test cell 201 parameter value that will test not the expression failure cause by the project correspondence carries out writing the 0xBF address after step-by-step and the operation, as, if only the ACPR test crash is arranged, then in the 0xBF address, write 0xFB; If EVM and two test crashs of RXGain are arranged, then in the 0xBF address, write 0xF5, promptly carry out step-by-step and operate the result that the back obtains with 0xF7 and 0xFD, ... by that analogy, after all can adopting the corresponding parameters value to carry out step-by-step and operate after the project testing failure arbitrarily, write the 0xBF address of memory in the base station equipment as faulty tag.After the veneer that breaks down turned back to veneer maintenance post, system can locate and maintenance time thereby significantly reduced according to the faulty tag information indicating maintenance personal's failure cause and the solution that store in the veneer.
