s1, setting a corresponding rectangular frame model on the screen according to the time range pressed by the finger of the user on the screen by using a gesture amplitude detection module, wherein the user can linearly amplify the sliding amplitude and curve of the file dragged by the effective area of the finger of the user in the rectangular frame model;
s2: the data transmission module is used for judging the equipment concentration corresponding to the sliding curve position of the finger effective area of the user, when the equipment concentration is dispersed, the single-to-multiple transmission needs to be carried out on the position and the included angle of the equipment, and when the equipment concentration is concentrated, a secret key can be set for the relevant equipment;
s3: using a reliability evaluation module, the user equipment scores the correctness of the files transmitted by other equipment, the file transmission rate and the total amount of the files received by different equipment within a preset time to transmit the files of the equipment, and judges whether the times of transmitting the files need to be adjusted in batches or not;
s4: the master control module is used for storing different equipment numbers and ranges corresponding to different curve radians, and meanwhile, the information of the stored radian curves can be called in time.
6. A data transmission method according to claim 5,the method is characterized in that: in step S1, the time when the user' S finger effective area clicks the rectangular frame area from the start is t1The corresponding time after the curve sliding is t2The effective area of the user's finger is t2-t1>t4File transmission is carried out in a time period when the effective area of the finger of the user is t3Return to t within time period1The starting point corresponding to the time, and t3<t5When the finger effective area of the user does not leave the rectangular frame area, the user can send the cancel file within the preset time, wherein t4、t5Is the set preset time period.
