全球首例！深圳地鐵11號線(xiàn)試行5G車(chē)地無(wú)線(xiàn)通信

2019-05-20 14:47來(lái)源：深圳地鐵

以11號線(xiàn)為例，一趟運行1小時(shí)的列車(chē)大約會(huì )產(chǎn)生25GB左右的數據?！笔芗夹g(shù)現狀制約，目前車(chē)地無(wú)線(xiàn)網(wǎng)絡(luò )帶寬不足，傳輸速率不穩定，車(chē)載數據基本無(wú)法實(shí)現及時(shí)下傳，只能儲存在車(chē)上的硬盤(pán)中，待列車(chē)下線(xiàn)后再由人工上車(chē)拷貝。不但耗時(shí)耗力，可靠性和實(shí)時(shí)性也無(wú)法保障，直接影響地鐵調度快捷、流暢地查看列車(chē)監控，也成為地鐵運維效率提升的限制瓶頸。
