| 摘 要： | 2.4 GHz频段是蓝牙、WIFI及很多无线设备使用的频段。在这个ISM开放频段内,设备使用中难免会受到相邻频段及正使用该频段的其他设备的干扰,造成信号传输效率低、质量差的情况。对此采用抑制干扰的手段是不现实的,而用规避干扰的办法来解决问题更具优越性、适应性。本文利用FHSS的基本原理,针对不同传输性质的煤气表抄表设备通信要求,采用同步固定跳频算法或自适应跳频算法来实现不同设备间的可靠数据传输,效果显著。 |

| Abstract: | The frequency bands of 2.4GHz is used by Bluetooth,WIFI and many wireless devices,In the ISM open band,many equipment which is working will inevitably be interference by adjacent frequency bands and the other equipment which is using the same frequency band,resulted of poor quality,low efficiency in signal transmission.this means the use of interference suppression is unrealistic,and to avoid interference with the solution to the problem will be more superiority and adaptability.In this paper,auchor uses FHSS principle,according to the communication requirements of different transmission properties on the gas meter reading device,use such as fixed frequency hopping algorithm or adaptive frequency hopping algorithm to achieve the reliable data transmission between different devices,the effect is significant. |
| Keywords: | FHSS wireless transmission system bluetooth interference 2 4GHz |
