The embodiment of the invention provides a temperature drift self-healing control method and device for a high-temperature aging table of an integrated circuit. The temperature drift self-healing control method for the high-temperature aging table of the integrated circuit comprises the following steps: acquiring first output results of at least two temperature sensors of a high-temperature test box of the aging table at the current moment and second output results of a plurality of historical moments; determining the distance between the temperature sensors at the current moment based on the first output result and the second output result; determining a weight corresponding to each temperature sensor according to the distance; determining the fault type of the target temperature sensor based on the first output result and the second output result under the condition that the target temperature sensor is determined to have a fault according to the weight; and performing fault correction on the target temperature sensor based on the fault type.

This application relates to a data acquisition method, apparatus, computer equipment, and storage medium. The method includes: acquiring the topology, operating status, and standard fault parameters of a target power grid; determining reference electrical characteristics of the target power grid based on the topology, operating status, and standard fault parameters; acquiring historical fault data and corresponding historical operating status; obtaining historical fault correction data using the historical fault data and reference electrical characteristics; wherein the fault correction data is used to characterize the difference between the fault data and the reference electrical characteristics; training a target model based on the historical fault correction data and historical operating status; wherein the target model is used to determine the fault correction data based on the operating status, and to determine the electrical characteristics of the target power grid based on the fault correction data. This method can improve the efficiency and accuracy of acquiring power grid electrical characteristics.
