Terminal use state identification method and device, computing equipment and storage medium

The invention discloses a terminal use state identification method and device, computing equipment and a storage medium. The method comprises the following steps: acquiring a network flow index value of a target terminal in at least one sampling time; obtaining a network flow index threshold value output by the network flow index threshold value model; comparing the network flow index value of any sampling time with a network flow index threshold value to identify normal use time from the sampling time; and determining a sleep time period and/or a normal use time period of the target terminal based on the normal use time. By adopting the scheme, the use state of the target terminal can be identified without installing a plug-in in each target terminal to monitor a screen locking or unlocking event, so that the user experience is improved, and the data security in the target terminal is guaranteed; moreover, the network flow index value of the scheme is obtained according to learning of a machine learning mode
