Abstract: Disclosed are a method and device for recognizing a two-dimensional bar code for improving the efficiency of recognizing the two-dimensional bar code. The method comprises: a relative position of a household appliance and a terminal device is determined during network configuration of the household appliance; a display parameter for displaying the two-dimensional bar code is determined according to the relative position, wherein the display parameter comprises a size of the two-dimensional bar code to be displayed and the two-dimensional bar code carries device information of the household appliance; the display parameter is sent to the household appliance to enable the household appliance to display a two-dimensional bar code picture according to the display parameter; and the two-dimensional bar code picture is recognized to obtain the device information of the household appliance.

Abstract: Disclosed are a sleep detection method and an apparatus, an electronic device and a storage medium. The sleep detection method includes: collecting pressure information from a bed; detecting the pressure information collected within a continuous preset duration, and determining whether the pressure information includes a sleep parameter of a body sign from a sleeping human; and if the pressure information includes the parameter of the sleeping human body sign, turning on a sleep detection function to perform the sleep detection. The sleep detection method and the apparatus, the electronic device and the storage medium can be applied to an apparatus having a sleep detection function, such that the sleep detection function in the apparatus having the sleep detection function is automatically turned on without a manual operation of a user, thereby saving time and labor.

Abstract: Disclosed are a method, a device and a computer-readable storage medium for registration and login. The method includes: receiving, on a registration device side, registration information used to register a first object; performing a registration operation corresponding to the first object according to the registration information; sending the registration information to a login device that subscribes to the registration information in advance after the registration operation is successful; receiving, on a login device side, the registration information used to successfully register the first object sent by a registration device; receiving login information used to login a second object; and performing a login operation corresponding to the second object if it is determined that the login information has not been used to register the second object and the login information matches the registration information sent by the registration device.

Abstract: Disclosed are a wireless bandwidth adjustment method, a wireless bandwidth adjustment apparatus, a terminal, and a storage medium. The wireless bandwidth adjustment method includes: determining a target IOT device and a bandwidth currently used by the target IOT device; collecting statistics on communication data of the target IOT device generated within a preset time period; determining a wireless bandwidth adjustment strategy based on the communication data; and adjusting the bandwidth based on the wireless bandwidth adjustment strategy.

Abstract: Disclosed are a method and an apparatus for wireless network configuration, a storage medium and a processor. The method includes: monitoring an execution result of a network configuration step in a wireless network configuration process; determining a corresponding failure reason when the execution result of the network configuration step is failure; and executing an operation corresponding to the failure reason. The operation comprises one of the following: outputting prompt information containing the failure reason and adjusting parameters of a network configuration device.
