The ATEstar universal test platform adopts the versatility and multi-threaded design concept to develop a universal test platform management system. The specific implementation is divided into two parts: configuration and operation. The configuration includes functions such as data input definition and display storage definition. The operation completes the equipment control and data acquisition and management functions according to the predetermined test flow according to the configuration parameters.
(1) Using virtual instrument and browser architecture mode, the system is easier to operate, easier to grasp, and user experience is more intuitive;
(2) Using DLL dynamic calling technology, a variety of data acquisition equipment can be flexibly configured, registered and invoked;
(3) Modeling using multi-level forms, tree structures or ATML texts, and flexible assembly and control of process sequences;
(4) The use of thread monitoring technology to achieve the system's fault monitoring, memory overhead, and exit mechanism security policy guarantees.
(5) Multi-threaded and dynamic linked list programming technology is used to realize data display and setting of multi-monitor, multi-window, multi-panel, and multi-controls. The window and panel can be dragged and zoomed, and various attributes can be edited online. That is, the results are updated in real time, and the settings such as position, size, and attributes can be automatically memorized without exiting the restart of the software. Gauge controls include digital text, temperature, tanker, slider, KNOB, dial, meter, and meter. Chart controls include graphical display controls and waveform display controls to meet the majority of industrial measurement and control demand.
The main function of ATEstar universal test platform(1) Test instruction of the tester;
(2) Driving of measuring instruments;
(3) Configuration of test function;
(4) Interpretation and preservation of test results.
Because the reconfigurable general-purpose automatic test system software needs to reconfigure the software function according to the loaded description file, functions such as XML file parsing, test resource allocation, and automatic configuration update are also required in the traditional test system software function.

It consists of three parts: the ATML test document description tool, the XML description file, and the general test system software. Different ATML test document description tools encapsulate relevant test information and configurations into XML description files that meet the ATML standard. For example, the test document description tool refers to Test DescripTIon.xsd as the main document, and a file named "Test Description.xml" is generated to describe the information related to the test task. When the universal test system software runs, the loaded xml file is first parsed into high-level code (for example, C, Basic) of the programming language, and then the corresponding operation is performed using the built-in compilation system of the development environment. Since the universal test system software can automatically match the test requirements with the instrument capabilities, the test resources can be allocated by operating the switch matrix, thereby achieving a signal-oriented software architecture and improving the interchangeability of the test instruments.
Key technologies involved in testing functional modules(1) Labwindows/CVI-based description file parsing and packaging technology
(2) Description of test sequence information and its packaging method
(3) Test sequence editing tool design ideas
(4) Reconfiguration of test sequences and reallocation of test resources
The software of the current universal test platform adopts this advanced design architecture, which has great advantages for improving the reusability of the entire measurement and control system and reducing the development cost. Taking the XX monitoring and control platform as an example, some software functions are shown.
