Research on Detection and Simulation Method of Electric Data Acquisition Link Based on Fault Injection Technology

Aiming at the problem that the current test items of China's electric data acquisition and testing laboratory are not in line with the actual use environment. This paper proposes a simulation scheme of electricity information acquisition link based on fault injection technology. Taking the intelligent electric meter as an example, this scheme uses fault injection technology such as signal interference and message tampering to simulate the abnormal working condition information of the field operation, and detects the function, performance and reliability of the intelligent electric meter in this environment. The comprehensive failure rate decreased by 75.64 % in different scenarios. In addition, the research also provides effective data support for the quality evaluation system of electric data acquisition of the intelligent electric meter, which can better meet the needs of electricity information collection in the actual use environment and improve the accuracy and reliability of detection.
