Please select the most similar patent number from A, B, C and D. Which number is?
Provided in the present invention are a method and a system for controlling a smart home by means of terminal positioning, the method comprising the following steps: starting up the positioning function of a terminal to acquire current position coordinates of the terminal; identifying the current position coordinates and, when determining a position away from the home, acquiring current temperature information; and, if the current temperature information is sunny, sending control information to the smart home, the smart information being used for opening the windows. The technical solution provided by the present invention has the advantage of good user experience.
A: The present invention provides an auxiliary positioning method and system. The method comprises the following steps: acquiring the GPS coordinate information of a current location; capturing the image information of the current location, and retrieving, according to the GPS coordinate information, gallery information of all floors that have the coordinate information; comparing the image information and the gallery information, and if the image information corresponds to a second image, determining the floor corresponding to the second image as the auxiliary information of the GPS coordinate information. The technical solution provided by the present invention has the advantage of good user experience.
B: Provided in the present invention are a terminal-positioning unmanned aerial vehicle control method and system, the method comprising the following steps: acquiring first position coordinates of a terminal and second position coordinates of an unmanned aerial vehicle; calculating a difference between an X value of the first position coordinates and an X value of the second position coordinates; if the difference is negative, receiving a user left turn command and replacing the left turn command with a right turn command. Technical solutions provided by the present invention have the advantage of good user experience.
C: Disclosed are a terminal system update method and system, the method comprising the following steps: obtaining a current system version of a terminal; detecting a system version of a network; if the system version of the network is higher than the current system version, and if the current time is late at night, directly performing system updating and upgrading. The present technical solution has the advantage of a good user experience.
D: A control method and device for a smart home. The control method comprises: acquiring the weather information of the region in which a terminal is located, and acquiring, from a smart home application, the state information of a target smart home, the smart home application being installed on the terminal (S102); synchronously displaying the state information and the weather information of the target smart home on the screen of the terminal (S104); receiving a trigger signal generated on the basis of the state information and the weather information (S106); and generating a control signal on the basis of the trigger signal, the control signal being used for controlling the operation state of the target smart home by means of the smart home application (S108). This invention solves the technical problem in the prior art of low convenience level of the smart home.
