【正文】 特征，可廣泛用于場橋的自動大車行走，自動大車糾偏，自動箱位管理等功能。利用 GPS系統(tǒng)可監(jiān)測大車兩側(cè)打滑情況，以利于同步控制。15 mm) * 電臺有效范圍： 3km * 電臺頻率可選范圍： 450470MHz； 或其它用戶申請頻率 * 標準 RS232 接口輸出，適用于各種 PLC 裝置 * 狀態(tài)量 8 位 ,24VDC 光耦隔離輸出 三、為了方便用戶選購，目前 ZPMC 可以提供兩種類型的 RTG 用 GPS 系統(tǒng)： 1．雙 GPS 系統(tǒng) —— 定位精度 177。 四 .RTG 防誤操作功能利用 RTG 大車的精確位置，并結(jié)合小車和起升機構(gòu)位置，組成 RTG 吊具的三維信息，根據(jù)碼頭堆場的實際布置，可轉(zhuǎn)換成具體的集裝箱大車箱位、小車堆位和起升層高 (BERTH， BAY, LANE／ STACK, TIER)等信息．此信息同要作業(yè)的集裝箱比較．如不符則禁止吊具動作，只有信息致才允許作業(yè)。通過空中均勻分布的 24 顆導航衛(wèi)星，保證了定位信號在全球任何地方任意時間全天候的可靠接收。中文 2295 字 Application of GPS on Yard Cranes Abstract： GPS is a satellite navigation and positioning system developed by America. Through 24 satellites evenly distributed in the air， the system ensures that positioning information could be well received all over the world at any time. Since the system was put into operation， it has been widely applied to uses such as oil surveying， ship and aircraft navigation， construction positioning and military operation. Key Words: GPS , cranes, Port Machinery GPS is a satellite navigation and positioning system developed by America. Through 24 satellites evenly distributed in the air， the system ensures that positioning information could be well received all over the world at any time. Since the system was put into operation， it has been widely applied to uses such as oil surveying， ship and aircraft navigation， construction positioning and military operation. ZPMC began the study of GPS application on yard cranes two years ago with the purpose of providing the RTG with functions such as reliable straight traveling of gantry and automatic container management like RMG (Rail Mounted Crane) while keeping the RTG of its flexibility on yard changing(through longitudinal traveling). The GPS products developed by ZPMC have a positioning accuracy a round177。自系統(tǒng)投入運行以來，已廣泛應用于國民經(jīng)濟的各行各業(yè)如石油勘探，船舶和航空導航，土建工程定位和重大軍事行動。這樣就保證了 RTG 無故障操作； 五． RTG 箱位自動管理利用 RTG 的三維位置，可隨時隨地發(fā)布 RTG 的操作信息譬如作業(yè)箱量作業(yè)位置， RTG 狀態(tài)等信息。15mm 左右，主要應用于： * RTG 大車自動糾偏 * RTG 大車自動行走 * RTG 箱位自動管理 * RTG 防誤操作功能 * RTG 定位監(jiān)控 (電子地圖 )功能 * 大跨距 RMG 同步控制 * AGV 自動導航 2．單 GPS 系統(tǒng) —— 定位精度可選 (177。 六．大跨距 RMG 和 QC 的同步控
