| 基于GPRS的凍土地溫遠程自動監(jiān)測系統(tǒng)設(shè)計(18 卷) |
| 英文標題 |
| Design of Automatic Detecting System of Permafrost Temperature based on GPRS |
| 摘要 |
| 針對凍土地溫遠程自動監(jiān)測的實際需求和實施條件，提出基于GPRS的凍土地溫遠程監(jiān)控系統(tǒng)的體系結(jié)構(gòu)和組成模塊，進行硬件原理設(shè)計、GPRS傳輸模塊數(shù)據(jù)接口及相關(guān)傳輸協(xié)議設(shè)計，并分析采集數(shù)據(jù)。經(jīng)應(yīng)用證明，系統(tǒng)可滿足凍土地溫長期自動觀測的需要。 |
