The Development Of An Intelligent And Wireless Monitoring System For Jogging Illegality

At present, international jogging matching is adjudged by umpires'naked eyes or tracking camera shooting by stages. Because these methods cannot guarantee umpires observe and adjudge every athlete in every step without any error during the whole course, omission of adjudication and error cannot be avoided. As a result, it's pressing to develop a real time, accurate and effective monitoring system for jogging illegality.The paper brings forward an intelligent and wireless monitoring system for jogging illegality. It consists of three types of subsystems: a tailor-made starting gun, athlete instruments and an umpire'central instrument. The tailor-made starting gun adds encryption and encoding circuit based on an ordinary starting gun, and it can uniformly reset all the athlete instruments. An athlete instrument can acquire an athlete's'vacate'illegality info and'knee-bending'illegality info separately by pressure sensors and strain sensors, and then encrypt and encode the info. After that, it transmits the info to the umpire'central instrument in the form of wireless. After the matching, an athlete can read the info stored in the athlete instrument by the accessory LCD. During the whole matching course, the umpire'central instrument itinerantly examines every athlete instrument, acquire the illegality info coming from every athlete instrument, and then transmit the info to the upper PC by an USB interface. The upper PC can store the info coming from the umpire'central instrument into a database and display the info by a software application.The system takes the sensors setting on the athlete'body as the illegality detective element, which guarantees the accuracy and real-time of acquired info, and can prevent omission of adjudication and error effectively. The wireless transmission in the system is highly safe and reliable after encryption and encoding. All the following projection in the system can effectively prevent cheating: the tailor-made starting gun uniformly resets all the athlete instruments, the umpire'central instrument itinerantly examines every athlete instrument all through and the illegality info in the umpire'central instrument and the athlete instruments maintain synchronic renewal. The system has complete performance and high intelligence. The technique has high practicability and economical signification, and fills the domestic vacancy.
