Abstract

The present disclosure related to a method for determining remaining service time for a filter in an air moving target device and an apparatus thereof, belonging to a field of Internet technology. The method includes acquiring operation information of the air moving target device, which includes power-on/off time of the target device, determining an average running wind speed of the target device according to the operation information, and determining the remaining service time of the target device according to the average running wind speed of the target device, attribute information of the target device and environment data. According to the present disclosure, by acquiring operation information of a target device and determining an average running wind speed of the target device according to the operation information, the remaining service time of the target device is thus determined according to the average running wind speed of the target device, attribute information of the target device and environment data. Since the remaining service time of the target device is determined according to some reliable data such as operation information of the target device, attribute information of the target device and environment data, the real use state of the device may be reflected more accurately.
