Intelligent table tennis bat

Abstract

The invention relates to an intelligent table tennis bat which comprises a handle as well as a left base plate and a right base plate which are oppositely arranged on two sides of the handle, wherein a gap is formed between the left base plate and the right base plate; a circuit board is arranged inside the gap; a plurality of piezoelectric film sensors are uniformly adhered to the inner surfaces on one side, facing to the circuit board, of the left base plate and the right base plate; a main control MCU (Microprogrammed Control Unit), a signal conditioning circuit, a memory and a communication interface circuit are welded on the circuit board; the output ends of the piezoelectric film sensors are connected with the input end of the signal conditioning circuit; the output end of the signal conditioning circuit is connected with the input end of the main control MCU; the input end and output end of the main control MCU communicate with a host computer through the communication interface circuit. By adopting the intelligent table tennis bat, useful data information in a table tennis training process can be obtained, an objective data source is provided for improving the training quality in future, acquisition on force position, frequency and the like in hitting a ping-pong is achieved, and the intelligent table tennis bat has the characteristic of intelligence, and is low in power consumption and compact in 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
