The embodiment of the application discloses a method and device for controlling a terminal. The specific implement of the method comprises the following steps: responding to determine a first terminalthat is playing contents will meet a presetting screen turn-off condition after a presetting duration, send a screen turn-off prompt message; the first terminal is in a children service module; the children service module provides the service for children users; receive a playing control message of the first terminal; the playing control message is sent basing on the screen turn-off prompt message and is used for setting the playing duration of the first terminal; according to the playing control message, send a control command to the first terminal, so as to control the first terminal to stop playing and turn off the screen; and, the control command includes the time for controlling the first terminal to stop playing and turn off the screen. The embodiment of the method realizes the elastic control of the first terminal.

The invention discloses an optical fiber time delay measurement method based on single optical frequency comb interference, which divides the optical carrier output by a narrow linewidth laser into two paths, wherein one optical carrier is modulated into an optical frequency comb signal by an optical frequency comb modulator , sent to the interferometer connected to the optical fiber to be tested, and another optical carrier for frequency shift processing; after the frequency shifted optical carrier is coupled with the optical signal output by the interferometer, photoelectric detection is performed to obtain a microwave signal carrying time delay information ; Extract the spectrum information of the microwave signal, and then extract the free spectrum range of the interference spectrum, and calculate the time delay of the optical fiber to be tested according to the free spectrum range of the interference spectrum. The invention also discloses an optical fiber time delay measurement device based on single optical frequency comb interference. Compared with the prior art, the invention has the advantages of high measurement stability, fast measurement speed, simple structure and low implementation cost.

The embodiment of the present invention relates to the technical field of electronic equipment, and discloses an intelligent control method for dictation based on user intentions and electronic equipment. The method includes: collecting voice corpus generated by the user in dictation mode, analyzing the voice corpus to obtain the user's current Intent, and detecting the user's dictation handwriting; the current intention indicates the user's dictation instruction; according to the corresponding relationship between the reported dictation audio and the dictation handwriting, acquire the target dictation audio that matches the current intention and report It can be seen that reading can realize flexible control of dictation by users, which is conducive to improving the intelligence of electronic devices in dictation reporting and reading, and improving user experience.

The invention discloses a method and a device for controlling the rotation of a 3D model, which are used for converting plane two-dimensional coordinates into three-dimensional three-dimensional coordinates, so as to easily control the rotation operation of the 3D model. The method includes: acquiring 3D model data, displaying the 3D model; detecting that the user slides the 3D model along a certain direction, and obtaining plane coordinate values ​​generated by the sliding; converting the plane coordinate values ​​generated by the sliding It is the space coordinate value of the 3D model; according to the change of the space coordinate value, the rotation of the 3D model is controlled. By calculating the position and size of the model in the space coordinate system, the equation of the circle where the model is located is obtained. When other computer input devices such as a mouse or a computer stylus operate on the model, the desktop coordinate plane coordinates are processed into world coordinates, and the mouse operation Behavior, rotate the model, and realize the flexible control of the model rotation.
