| 鐵路無線通信便攜式話音記錄與中繼系統(tǒng)設計(18 卷) |
| 英文標題 |
| Design of Railway Wireless Communications portable voice recording and Relay System |
| 摘要 |
| 基于鐵路無線列調通信系統(tǒng)，研究并設計了一款便攜式語音記錄和中繼設備，從而實現(xiàn)無縫接入鐵路無線列調通信系統(tǒng)，使其網(wǎng)內所有無線網(wǎng)絡設備中的模擬話音都轉化為數(shù)字語音并以語音文件形式存儲于SD存儲卡上實現(xiàn)記錄功能，還可以通過微機檢索方式查詢記錄下來的語音文件。該設 |
