What it claimed is: 
     
         1 . A tennis training robot, comprising a housing and driving wheels mounted at a bottom of the housing, the driving wheels are driven by a driving motor, a ball entry area is formed at an upper part of the housing, a ball serving area is formed at a lower part of the housing, a ball entry opening is formed in the ball entry area, the ball serving area is provided with a ball rotating disk, a track and a set of ball serving wheels, the ball rotating disk is arranged below the ball entry opening, the ball rotating disk is controlled by a ball entry motor, the track is arranged below the ball rotating disk, and the set of ball serving wheels are arranged at the track; and the set of ball serving wheels comprises an upper ball serving wheel and a lower ball serving wheel, and a ball serving opening is formed on the housing in a ball release direction of the upper ball serving wheel and the lower ball serving wheel. 
     
     
         2 . The tennis training robot according to  claim 1 , wherein a plurality of ball rotating ports are formed on the ball rotating disk, a ball rotating rack is mounted in a middle of the ball rotating disk, and a center of the ball rotating rack below the ball rotating disk is connected to the ball entry motor. 
     
     
         3 . The tennis training robot according to  claim 1 , wherein the track is arranged below the ball rotating disk in an overlapped form, and the track comprises a transition section and a slope section connected to the transition section. 
     
     
         4 . The tennis training robot according to  claim 1 , wherein the upper ball serving wheel is arranged above the track, and the lower ball serving wheel is arranged in an extension direction of the track. 
     
     
         5 . The tennis training robot according to  claim 1 , wherein the tennis training robot controls the ball serving through a control system, wherein the control system comprises a main controller, a gyroscope, a Hall effect sensor and a dual-camera image recognition system, wherein the main controller drives the ball entry motor, a ball serving motor and a driving wheel motor by connecting to driving circuits, the gyroscope, the Hall effect sensor and the dual-camera image recognition system are all electrically connected to the main controller, and the main controller is further electrically connected to a mobile phone APP. 
     
     
         6 . A training method of the tennis training robot according to  claim 5 , comprising the following steps:
 (step 1) selecting a designated mode, a random mode, an intelligent level mode and other different sports modes suitable for an athlete's level on the mobile phone APP;   (step 2) performing movement positioning to serve a tennis ball, and simulating ball returning and a battle training according to the mode selected on the APP, wherein the main controller controls the driving wheels to move, and the gyroscope and the Hall effect sensor provide a real-time feedback signal to keep a movement direction stable;   (step 3) predicting a trajectory and a placement of an incoming tennis ball according to a ball returning from a player, and performing movement positioning to simulate returning, wherein the dual-camera image recognition system captures multi-point three-dimensional coordinates, a speed and a speed direction of a running tennis ball, and an algorithm model is used to calculation a direction of the incoming tennis ball and predict a placement of the incoming tennis ball; and   (step 4) obtaining hitting data of the athlete and submitting the data to the main controller for determining and identifying a player level, so as to implement simulated battle training at a corresponding level.
