Monitoring system data correction method and device, storage medium and electronic equipment

The invention relates to a monitoring system data correction method and device, a storage medium and electronic equipment, and the correction method comprises the steps that first expansion data and second expansion data are determined, the first expansion data are expansion data obtained from a monitoring system, the monitoring system is used for monitoring an expansion indicator of a boiler, and the second expansion data are expansion data obtained from the monitoring system; the second expansion data is the expansion data acquired from the expansion indicator; and correcting the first expansion data according to the second expansion data to obtain corrected expansion data. The first expansion data is corrected through the second expansion data, the accuracy of obtaining the first expansion data from the monitoring system can be improved, and then the accuracy of judging the operation condition of the boiler can be improved. 本公开涉及监控系统数据的校正方法、装置、存储介质及电子设备，其中校正方法包括：确定第一膨胀数据以及第二膨胀数据，所述第一膨胀数据为从监控系统中获取的膨胀数据，所述监控
