【正文】 ystem in China 在 2022年 12月 3日，我們開展了“兩港一航” 工業(yè)性試驗，中國第一條裝有電子標簽的集裝箱航線“浙海 325”輪從煙臺正式起航，在上海港至煙臺港這條航線上完全實現了集裝箱運輸環(huán)節(jié)的自動識別和實時信息交換，截至 2022年 1月 19日 ,“兩港一航”示范線箱量累計完成 5294TEU。 1 line” on Dec 3, 2022 and the first line of containers with RFID”Zhehai 325 Shipping” in China has been formally started. This line from Shanghai port to Yantai port has absolutely shown automatic identification and realtime information exchange in container shipping. By Jan 19, 2022, the container throughput of this demonstrative line has reached 5294TEU. 示范線總體框架 General frame of Application amp。 demonstration line of “2 ports amp。 1 line” container RFID system 第一艘載著貼電子標簽的集裝箱班輪 “ 浙海 325”輪從煙臺開往上海 The first regular container ship ”Zhehai 325 Shipping ” with RFID drive to Shanghai from Yantai 浙海 325停靠龍吳港成功卸船 Zhehai 325 Shipping stops at Longwu port for unload 龍吳港作業(yè)現場 Operating spot at Longwu port 煙臺港作業(yè)現場 Operating spot at Yantai port 演示錄像 Demonstrative Video 集裝箱電子標簽自動識別 系統(tǒng) Container RFID Automatic Identification System 無線通信系統(tǒng) Wireless Communication System 信息實時交換系統(tǒng) Realtime Information Exchange System 裝拆箱點的數據輸入系統(tǒng) Data Input System of Container Stuffing Point 自動識別應用系統(tǒng)體系結構 Structure of RFID automatic identification application system 基于電子標簽自動識別系統(tǒng)的港口信息安全管理技術 Port safety management technology based on RFID automatic identification system ? 建設滿足集裝箱電子標簽示范系統(tǒng)需求的多級安全性機制，建立安全認證系統(tǒng)和日志分析系統(tǒng)； Establish multilevel safety system as required by container RFID demonstration system and establish safety certification system and log analysis system。 ? 研究電子標簽讀寫器和主機間的信息通信加密技術； Research on encrypt technology of information munication between the reader and host puter。 Research on safety supporting system in container information realtime exchange system. 主要關鍵技術和設備 Key Technology amp。 Discussion on which frequency range RFID in container should adopt is always a hot, which focuses on which one in the three frequency ranges 433MHz, 916MHz and is the most applicable for RFID in container. ? 頻段選擇時，考慮的主要性能參數： When choosing frequency range, consider the following chief parameters: ?最大通信距離 ； Max munication distance ?無線信號的傳播 ； Transmission of wireless signal ?功率限制 ； Power limit ?工作時間 ； Working hours ?調制方式。國內外研究表明頻段從技術角度來看不是關鍵問題。 event record of door openingamp。 Antenna 煙臺港道口處的基站式讀寫器和天線 Fixed reader at Gate of Yantai Port 8. 無線式讀寫器 Wireless reader ? 采用 ISM Adopt ISM for working frequency range ? 支持無線方式與上位機通訊，與集裝箱電子標簽橋接器配對使用 Support wireless mode and upper machine munication, match with bridge of container RFID system for use ? 支持哨兵模式下的局域空間無線訪問 Support wireless visiting in local area space under sentinel mode ? 加密計算與認證，確保數據安全，防止鏈路竊聽與數據破解 Encrypting calculation and certification to ensure data safety and prevent from wiretapping or data breaking ? 使用頻道隔離技術，多個設備互不干擾 Adopt frequency range seclusion to avoid interferences among multiple equipment ? 防碰撞技術，支持多標簽讀寫 Anticollision technology ? 配置微波模塊工作方式，發(fā)射功率軟件可調 Possible to equip with microwave module working mode and radio frequency oftware is adjustable 9. 電子哨兵 E－ Sentinel ? 利用無源電子標簽的工作原理，通過電磁波供電激活集裝箱電子標簽中的 125KHz低頻電路工作 Under the working principle of passive RFID, activate 125k low frequency circuit in RFID in container through electromagic wave power supply ? 支持非工作狀態(tài)的休眠模式和快速喚醒啟動的模式切換 Support switch between dormancy mode and rapid awaking /startup mode under nonop
