| As the world has entered the 21st century, globalization is bringing people to the concept of space-time great changes, the world has become a "global village." With globalization, tourists will reach an unprecedented scale large, the tourism industry has become the most potential industry and one of the key industries in developed countries. How to introduced the new communications technology into the tourism industry to improve the service quality of tourism, has gained much more focus.The research issue from the 2.4G guide-headset project of Rosstone company that customers 2.4G guide for headphones System Project. In the traditional tour team, tour guides broadcast words by loudspeakers to the tourists. it is have much drawbacks of in this way. So the project provided a new broadcast which use wireless communication.Firstly, this article proposes the overall design plan for system hardware platform based on function requirement. Then,selected the nRF24L01 as the chip ofWireless Commnication in view of the require of data communication. at the last, The essay elaborates the system design.Secondly, this paper discusses the specific hardware implementation process of the electronic guide system. The emphasis is on the design of audio low noise amplifier module and the design of the antenna miniature. Low noise amplifier module audio workload embodied in the commissioning of the more hardware. And for the miniaturization of antenna design, this article through to the antenna miniaturization comparison, choose the meander-line as a means of realization of the antenna miniaturization. Through the ADS simulation research the antenna bend the influence of the structure of the antenna, and based on this, puts forward a printed pour F bend the model of the antenna. Through the real test, is proved to be practical.Finally, In this thesis, an improved protocol which has higher throughout efficiency and the lower average transmission time is presented based on the research on current routing algorithms. The throughout Efficiency of the new protocol is higher than that of the original,and its average transmission time is less than that of the original.then, the design of soft system which is used in electronic guide system is proposed. |
