Historical data online re-calculation method and system, computer and storage medium

The invention provides a historical data online re-calculation method and system, a computer and a storage medium, and the method comprises the steps: obtaining a baseline value of historical data of equipment, and judging whether the baseline value is equal to a normal data baseline value of the equipment in a normal working state or not; if the baseline value is not equal to a normal data baseline value of the equipment in a normal working state, acquiring a time period corresponding to the historical data, and inversely calculating an initial value of the historical data according to a corresponding first calculation formula; and filling the initial value into an online platform, calculating real data corresponding to the historical data according to a time period corresponding to the historical data, eliminating external non-real data, and retaining real equipment data. 本发明提供了历史数据线上重计算方法、系统、计算机及存储介质，所述方法包括获取设备的历史数据的基线值，判断所述基线值是否等于所述设备正常工作状态下的正常数据基线值；若所述基线值是不等于所述设备正常工作状态下的正常数据基线值，则获取所述历史数据对应的时间段，并根据对应的第一计算
