Specific implementation mode
Present invention will now be described in further detail with reference to the embodiments and the accompanying drawings, but embodiments of the present invention are unlimited
In this.
As shown in Figure 1, a kind of automatization test system based on MATLAB is present embodiments provided, including control unit,
Test cell and unit under test, control unit are connect with test cell and unit under test respectively, test cell and unit under test
Connection, control unit is by the state of MATLAB programming Controls test cell and unit under test, and the data that output test result；It surveys
Examination unit is used to receive the signal of unit under test transmission or provides test signal for unit under test；Unit under test is tested for sending
Signal receives the test signal that test cell is sent out.
Wherein, test cell may include having multiple, GPIB connecting lines is respectively adopted, each test cell is connected to control list
Then each test cell is connected to unit under test by member.
Control unit is connect by universal asynchronous receiving-transmitting transmitter (UART) with unit under test.The UART in radio products
It is most common interface, it is good using the interface generality.
Control unit is connect by general purpose interface bus (GPIB) with test cell.General purpose interface bus is measuring instrument
General standard interface, therefore this automatization test system has very strong versatility.
Test cell can be signal source, frequency spectrograph, comprehensive test instrument, ammeter or voltmeter, can also be that having GPIB connects
Other test equipments of mouth.Control unit passes through UART interface or gpib interface to the control command of unit under test and test cell
It is sent out in the form of character string.
Test output result includes data form part, data depicted portion and test result part.Test result can root
Corresponding format output is generated according to demand, and result is shown with visual chart, is conveniently checked.
As shown in Fig. 2, present embodiments provide another automatization test system based on MATLAB, the embodiment with it is upper
In one embodiment automatization test system the difference is that, control unit passes through general purpose interface bus and one of test is single
Member connects, and passes through general purpose interface bus between test cell and extends line connection.Specifically, control unit is connected to by GPIB extractions
Then test cell 1 extends line by GPIB and connect test cell 1 with test cell 2.Namely when the survey of control terminal connection
When test instrument is more, the connection that GPIB extension lines can be used that GPIB lines is replaced to realize test cell and control unit, GPIB extensions
Line ratio GPIB lines are at low cost, while being not take up the interface of control unit, as control unit be computer when, the USB of computer can be saved
Port.
As shown in figure 3, present embodiments providing a kind of automatic test approach based on MATLAB, this method includes following step
Suddenly：
Step 1: control unit is programmed by MATLAB, add or delete test item；
Step 2: control unit is connect with unit under test, serial ports is created in MATLAB, and has configured serial ports parameter, is beaten
Open string mouth；
Step 3: control unit is connect with test cell, test cell object is created in MATLAB, and configures good connection
Parameter opens object；
Step 4: control unit control test cell is operated in i.e. by state needed for test item, control unit control is tested
Unit is in corresponding working state, delay to unit under test stable working state；
Step 5: control unit read test cell data or unit under test data, and preserved after MATLAB is handled；
Step 6: control unit judges whether test item meets the requirements, if met the requirements, next test is carried out
, and step 4 is repeated to step 6, if being unsatisfactory for requiring, then follow the steps seven；
The data Step 7: control unit outputs test result.
In step 1, add or delete test item can be corresponding macro to each test item establishment one in MATLAB, when
When being 1, indicate that the test item is added；When for 0, indicate to test without this, example is as follows：
RX_GAIN_TEST=1；
TX_POWER_TEST=1；
……
It is compared to automated test tool to need in sequence to test, it usually needs complete all test items, ability
It obtains a certain test result, cannot achieve and only choose fc-specific test FC item to be tested.In step 1, add or delete test item
Can only be added according to testing requirement needs test item to be tested, and the testing sequence of each test item can be adjusted flexibly.
Serial ports parameter is serial port, baud rate, data bit, time-out time etc. in step 2.
Control unit is connect by gpib interface with test cell in step 3, and (such as by instrument control software
Keysight IO Libraries Suite) it scans the main address of instrument (PrimaryAddress) of each measuring instrument and establishes
Link, using the tmtool tools in MATLAB, scans the GPIB card numbers (BoardIndex) of linked instrument.For each
Object is respectively created in instrument, and the connections such as connection type (type), GPIB card numbers and instrument main address ginseng has been configured in MATLAB
Number, and open object.
In step 5 control unit can repeatedly read test cell data or unit under test data, to same test item,
Repeatedly test is averaged as a result, making reliable test result cycle.By GPIB lines by query order read test cell datas or
Person reads the corresponding data of unit under test by UART serial ports, is preserved into array after MATLAB is handled.
In step 7, test data may be output in EXCEL, and draw data profile, export test result, and print
Prompt is completed.
As shown in figure 4, present embodiments provide another automated testing method based on MATLAB, the embodiment with it is upper
In one embodiment automated testing method the difference is that, in step 6, control unit without judge, but successively will
Each test item executes step 7 after the completion of all testing.Whether control unit carries out judge being determined according to actual test demand
, in production if need to only pick out non-defective unit or defective products, carry out whether test item meets if control unit in step 6
It is required that judgement, just terminate to test to after picking out non-defective unit or defective products, the test of whole test items need not be completed.But
In R＆D process, it usually needs the indices for knowing research and development product, for analyzing Curve guide impeller, the control unit in step 6
The judgement then whether met the requirements without test item terminates test after being sequentially completed each test item.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
