The invention relates to a data processing method and device and electronic equipment. The data processing method comprises the following steps: acquiring alarm information of the mechanical equipmentaccording to a preset time interval, acquiring a plurality of pieces of alarm data of which the data format is a first data format according to each piece of alarm information, and creating an alarmrecord which comprises a plurality of pieces of alarm data and a corresponding relationship between the plurality of pieces of alarm data and a plurality of pieces of acquisition time. Thus, the alarmdata of any target time can be inquired according to the created alarm record, and a reliable basis is provided for performance research of the mechanical equipment so as to determine whether the performance of the mechanical equipment has a potential problem or not.
