Abstract
The invention discloses a movement path recording device for throwing training based on an MEMS (Micro-Electro Mechanical Systems) accelerometer. The movement path recording device consists of a microprocessor, the MEMS accelerometer, a file management control chip, an NAND Flash storage chip, a clock chip, a button-shaped lithium ion battery, an LED (Light-Emitting Diode) state indicator lamp and a USB (Universal Serial Bus) data interface. The movement path recording device has small volume and light weight and can be directly fixed on a throwing machine by using a rubber belt; the microprocessor is used for collecting and recording data of accelerated velocities in a throwing process of the machine. The recorded data can be read through the USB interface after training, and a movement path in a machine throwing process is subjected to complete curve drawing by using data post-processing software, so the grasping situation of throwing skills can be visually and scientifically obtained by participating trainees. The movement path recording device provided by the invention is particularly applicable to fields such as javelin, shot, discus and grenade-throwing training in troops; the training effect is greatly improved; the movement path recording device has the advantages of low cost, simplicity and convenience in operation, and high reliability.
