Research and development of swimming training information system based on ZigBee technology

Based on the high level swimming teams of Tongji University This essay introduces a specific training information system used in swimming which was built by the skill of electrommunication, network communication and database technology. In this system, using the ZigBee transmission technology, a wireless real-time timer technique was adopted and communication master station was used. As a result, timing data can be real-time transmitted, stored and analyzed. Owing to the special-used hardware and software, various functions, such as setting up single or multiple timing device network, split time data and toal time data acquisition, data gathering, data exhibition, data inquiring, data storing and data analysis, can be achieved. The use of the system can help coaches solve the problem on dealing with the data, which could be great helpful in improving work efficiency. This system is useful for not only swimming, but also for other kinds of sports needing timed, such as cycling, track and field, Modern Pentathlon and skating.
