Smart Table Tennis Racket

Abstract

The invention relates to an intelligent table tennis racket, which comprises a handle and left and right substrates relatively arranged on both sides of the racket. There is a gap between the left and right substrates, and a circuit board is arranged in the gap. A plurality of piezoelectric film sensors are evenly pasted on the inner surface of the side, the main control MCU, signal conditioning circuit, memory and communication interface circuit are welded on the circuit board, the output end of the piezoelectric film sensor is connected with the input end of the signal conditioning circuit, and the signal conditioning circuit The output end of the circuit is connected with the input end of the main control MCU, and the input and output ends of the main control MCU communicate with the upper computer through the communication interface circuit. The invention can obtain useful data information in the table tennis training process, provide an objective data source for improving the training quality in the future, and realize the acquisition of information such as table tennis hitting strength, position and hitting frequency, and has the characteristics of intelligence. In addition, low power consumption and compact structure.

Description

technical field [0001] The invention relates to the technical field of front-end equipment of a table tennis intelligent data collection and statistics system, in particular to an intelligent table tennis racket. Background technique [0002] At present, the contact surface between the table tennis racket and the table tennis ball usually adopts a wooden board of a certain material as a support, and then glues rubber with specific properties on both sides of the supporting wooden board to bounce back and forth to the table tennis ball. In the actual table tennis training and competition process, the hitting position, strength and hitting frequency of the table tennis directly affect the results of training and competition. However, ordinary table tennis rackets cannot provide training and competition, especially during training. Position, strength, hitting frequency and other information cannot provide objective relevant data to coaches and athletes, resulting in a certain d...

In the actual table tennis training and competition process, the hitting position, strength and hitting frequency of the table tennis directly affect the results of training and competition. However, ordinary table tennis rackets cannot provide training and competition, especially during training. Position, strength, hitting frequency and other information, so that it is impossible to provide objective relevant data to coaches and athletes, resulting in a certain degree of blindness in training
