| 摘 要： | 选用TI公司推出的跳频扩频(FHSS)无线通用异步接收/发送器(UART)芯片组Dolphin,提出了构成大型无线表决系统的方案.该方案采用跳频技术,成功地解决了在多用户环境下的信号窜扰的问题,而用户却无需开发跳频协议.同时,实测200m的有效半径也能保证各种应用场合尤其是大型会场的运用.得益于Dolphin芯片组的引入,方案更具有保密性好、传输距离远、易于开发及可扩展性强的特点.

| Abstract: | The 'Dolphin' frequency hopping wireless(FHss) UART chipset from TI is adopted to construct a large-scale wireless voting system solution.With the merits of the FHSS,it solves the interruption problem when it is used in a multi-user environment,while users are not required to develop the protocol of FHSS.In addition,the effective transmitting radius is proven to reach as long as 200 m,which contributes to the extensive application especially in long-range meetings occasions.The solution figures security,long effective range,ease of development and strong function-extension,which come with the utilization of Dolphin chipset. |
