Abstract
Aiming at the digital device test, design a automatic test system, introduced the concept, architecture and technology. The PC sends SMV to digital device based on IEC61850-9-2, Then receive real data from device through the PC serial based on IEC103, constructing a loop, then completed the test. Software static structure adopts the modular programming, dynamic data exchange uses multithread. According to the configured test case, test items can be completed automatically. The system is based on PC, compared with the traditional test instrument to save hardware cost. With the help of calculation and control capabilities of the PC, realize the automatic testing, make people liberation from repetitive work, more focused on the analysis of test results, improve test quality and efficiency.
