Abstract:According to the function and performance verification requirements of long-term working measurement and control equipment,a test idea based on design level is designed according to the principle of measurement and control equipment,which provides simulation verification conditions for long-term working measurement and control equipment. By embedding the test function into the product, the test of external non measurable index parameters is injected into the product from the design level, especially the change trend monitoring of the internal signals of the module and the change monitoring of the operating environment, etc.Combined with dynamic test, fault injection test and other means to collect long-term running test data, and evaluate the trends and the faults,to get the health or fault degree of the measurement and control equipment.This method has more prominent fault triggering capability and assessment capability of product function and performance.
