Key technology areas
Development Tools: Labview
Distributed data interconnection: Based on the development of endurance test test platforms, each module shares the same data and control bus, distributed layout, and work together to meet all mainstream endurance test requirements
State Machines and Servers: The use of state machines and servers to make the architecture clear, facilitate the completion of additional function extensions, and increase the code reuse rate
User Management: User Authority Control, MD5 User Password Save
Real-time data display: All channels of real-time data, protection of upper and lower limit value display
Equipment alarm information: save recording equipment alarms to help investigate the cause of the problem
Test Sequence Control: Import/Preview test curve, precise control of test procedure

Test curve generation function
According to the mainstream failure model, a recommended universal test line can be established to help customers quickly verify product durability performance when the test conditions cannot be determined in the early stage of product development.
