Fault detection method and system, electronic equipment and storage medium

The embodiment of the invention provides a fault detection method and system, electronic equipment and a storage medium. The fault detection method comprises the following steps: in response to a detection instruction for indicating fault detection, controlling a display device to be detected to display a preset reference image set, and acquiring power consumption detection data of the reference image set displayed by the display device to be detected through a power consumption acquisition device; and comparing pre-stored power consumption reference data corresponding to the to-be-detected display device with the power consumption detection data to determine whether the to-be-detected display device has a fault. 本公开实施例提供一种故障检测方法、系统、电子设备及存储介质。该故障检测方法包括：响应于用于指示进行故障检测的检测指令，控制待检测的显示装置显示预设的基准图像集，并通过功耗采集装置获取所述待检测的显示装置显示所述基准图像集的功耗检测数据；通过将所述待检测的显示装置对应的预先存储的功耗基准数据与所述功耗检测数据进行对比，确定所述待检测的显示装置是否存在故障。
