| With the rapid development of global economic and technology, improvement of people's living standards and aesthetics, a growing number of large gymnastic performances are applied in the opening ceremony of sports events. However, its developing speed is very slow due to some problems, such as long training time and monotonic transformation of performing apparel.Firstly, the feasibility of wireless communication network is studied on the problems of photovoltaic technology in modern gymnastics. Secondly,several major wireless communication technologies are analyzed. Thirdly, Wireless communication module is designed with CC2430 chip that supports IEEE802.15.4 protocal is used as hardware platform. TinyOS operating system which supplies wireless sensor network is used as software platform .And then, hardware circuit of base station and performing node is given .Software development platform is built. Application programs are designed in order to finish group control; MAC data load frame is studied and designed; Multi-coordinator and multi-hop technology is proposed to solve the problem on large-capacity and long-distance communication of network.Lastly, the designed system is tested .The relationship between performance effect and the data frame format and the refreshing frequency of performing node is also analyzed. |
