該系統由防爆基站控制器KTW 5、防爆基站KTW 6、防爆電源KDW 2 4和光端機KTG3等組成。

On the basis of study of the effection factors for communication frequencies caused by underground geology condition and production condition, a relatively good frequency group of wireless communication transmission in underground was defined, and the distributing scheme of base-station in underground cellular communication was offered.

在研究了井下地質條件和生產環境對通信頻率的影響因素基礎上,確定了井下無線通信傳輸的較佳頻段,并提供了井下蜂窩通信基站的布置方案。

Typical sensor nodes pos-sess limited energy,computation and memory resources,and the security of communication among nodes is traditionally realized by configuring base-stations which has the properties of possessing more energy,holding more bandwidth and covering wider area.

普通的傳感器結點電池電量低、計算能力弱和存儲容量小,傳統的通訊策略通過設置電池電量高、通訊帶寬高、覆蓋范圍廣的基站實現結點之間的安全通訊,但基站易于因遭受攻擊或負擔過重而無法正常工作,從而導致網絡的癱瘓。
