Long-range amplification controller is for grinding instrument certainly.
Design of System Software:
Adopt the development environment of the Lab Windows/CVI of NI company as this test system and test software, the user interface that it is good, based on the development environment of C language, powerful built-in function and debugging method have conveniently greatly shortened the construction cycle.
This testing software has the function of system configuration, testing scheme configuration, test process control, test data processing.Wherein, system configuration mainly is that the interface to equipment is configured, as the connected mode of equipment, port, address etc.This is that test macro is necessary, and system test software is remembered these configurations automatically so that do not need the user to be provided with once more when calling next time.Testing scheme is the core of test macro, it has comprised testing process, the configuration of test point and parameter etc., require the user to be familiar with the flow process of test job and the principle of work of software, so that operating personnel can carry out proper configuration to the parameter of testing scheme by close friend's interface, the information of software prompt is done correct response.In native system, the user can be provided with by the parameter of interface to test.Test process control, in the test process, software is provided with instrument and equipment according to set testing procedure scheme, scheduling, and after test is finished from testing apparatus reading of data, the user can control the flow process of test macro as required, understands task executions situation etc. in real time, has good procedural information and shows and condition prompting.Test data is handled, and after testing successfully end, testing software is deposited into test data in the test result data storehouse, and submits to user's demonstration from test result data generation data sheet, comprises in the form accurately and sufficient information.The user can this form of selective printing, the test result form can be stored in the mode of file, also can read historical test result file, and the content that software can display file is also printed.
Testing software can finish the automatic test to technical performance index in the scheme, and software is finished test by scheduling signals source, turntable and spectrum analyzer, and basic control flow as shown in Figure 2.
The design's advantage:
Existing relatively test macro, the native system design has following advantage:
Building of this test macro saved the millimeter wave testing tool of half, greatly reduced testing cost.
This system also can finish the test to the antenna index of correlation except realizing the test of front end.
Have good user interface, system configuration interface and operation prompt information to be user-friendly to and testing process is monitored;
Allow the user that self-defined configuration is carried out in test;
The user can be provided with the system instrument correlation parameter;
Test result data is managed, and energy generation, preservation and printing test form.
The design has been successfully applied in the index of correlation test of front end, and checking shows through test of many times: can substitute other existing manual testing system fully, and manipulate more simply, conveniently, strengthen the reliability of system.
