Table tennis ball serving mechanism control system based on single-chip microcomputer

Abstract

The invention relates to a single-chip microcomputer-based table tennis ball control system, which is characterized in that it comprises: a single-chip microprocessor, and the single-chip microprocessor is mainly used for processing a keyboard module connected thereto, an infrared receiving circuit module, and a motor speed measurement module And the data sent by the software algorithm regulator module, and then output the driving signal of the motor to the motor driving circuit module; the keyboard module is used to input the control command signal of serving; the infrared receiving circuit module is used to receive signals; the motor speed measurement module, It is used to measure the motor speed, so that the single-chip microprocessor can calculate the error value compared with the given speed value; the software algorithm regulator module is used to adjust the error value between the given speed and the actual speed of the motor; the motor drive The circuit module is used to drive the motor. The invention can not only improve the serving performance, but also reduce the cost of the table tennis serving machine.

Description

technical field [0001] The invention relates to a single-chip microcomputer-based control system for a table tennis ball serving mechanism. Background technique [0002] refer to figure 1 , the design idea of ​​the current automatic table tennis ball machine is: the table tennis ball in the ball storage mechanism falls into the conveying mechanism by its own gravity, and the conveying wheel sends the ball into the ball sending channel through the semicircular ball locking groove on it. Arranged in a row in the channel, adjusting the speed and direction of rotation of the two wheels can achieve different rotation directions of the ball; the adjustment device in the launching mechanism can adjust the height of the ball outlet to change the arc of the ball. Adjust the left and right angles of the ball through the swing mechanism. The basic principle of its serving is to utilize the principle of the pair of runners. The table tennis ball can obtain a certain initial speed due ...

Problems solved by technology

[0004] And table tennis is our national game, and there are a wide range of fans in our country. At present, the existing ball machines are used for professional training, with high technical requirements and high cost, which is not conducive to the use of amateur table tennis fans, and is even more unfavorable for families The use of setting hinders the widespread popularization of table tennis
