8. The device screen saver unlocking method of claim 1, wherein the device side receives the bluetooth packet data based on a bluetooth standard interface and analyzes the bluetooth packet data to obtain an unlocking command and an unlocking password of the bluetooth packet data, comprising:
the equipment terminal calls a first unlocking application and receives the Bluetooth packet data through a Bluetooth standard interface of the Android;
the equipment terminal analyzes the Bluetooth packet data based on the first unlocking application to obtain an unlocking command and an unlocking password of the Bluetooth packet data.
9. An apparatus for unlocking a screen saver of a device based on bluetooth communication, the apparatus comprising:
a broadcasting module: the main Bluetooth device used on the device end broadcasts the identification information of the device end as a broadcast signal in real time;
establishing a connection module: the method comprises the steps that a slave Bluetooth device used for a user terminal establishes Bluetooth connection with a device terminal based on a broadcast signal broadcasted in real time;
a sending module: the user terminal is used for sending Bluetooth packet data for unlocking the screen saver of the equipment end to the equipment end after the Bluetooth connection is established between the user terminal and the equipment end, wherein the Bluetooth packet data comprises an unlocking command and an unlocking password;
an analysis module: the equipment base receives the Bluetooth packet data based on a Bluetooth standard interface and analyzes the Bluetooth packet data to obtain an unlocking command and an unlocking password of the Bluetooth packet data;
a matching unlocking module: and the device terminal uses the unlocking password for matching based on the unlocking command and unlocks the screen saver after the matching is successful.
10. A device screen saver unlocking system based on bluetooth communication, the system comprising: the device comprises a device end and a user terminal; the device side comprises a main Bluetooth device and a first unlocking application; the user terminal comprises a slave Bluetooth device and a second unlocking application; the device side establishes Bluetooth connection with the slave Bluetooth device of the user terminal based on the master Bluetooth device; wherein the system is configured to perform the device screen saver unlocking method of any one of claims 1-8.
