在慢性病管理領域，隨訪包作為核心數據采集終端，其數據傳輸方式的多樣性直接決定了醫療服務的可及性與管理效率。當前慢病隨訪包已形成無線傳輸為主、有線傳輸為輔的技術體系，并通過標準化協議與安全機制構建起完整的醫療數據生態鏈。

　　In the field of chronic disease management, follow-up packages serve as the core data collection terminal, and the diversity of their data transmission methods directly determines the accessibility and management efficiency of medical services. The current chronic disease follow-up package has formed a technical system mainly based on wireless transmission and supplemented by wired transmission, and has built a complete medical data ecosystem through standardized protocols and security mechanisms.

　　一、無線傳輸技術矩陣

　　1、 Wireless Transmission Technology Matrix

　　藍牙傳輸系統

　　Bluetooth transmission system

　　作為短距離無線傳輸的核心方案，藍牙技術通過低功耗協議（BLE）實現設備與移動終端的穩定連接。隨訪包內置的藍牙模塊可自動識別3米范圍內的智能手機或平板設備，建立加密傳輸通道。該技術特別適用于家庭場景，患者自主測量后，血壓、血糖等生理參數可即時同步至專用APP，數據完整率達99.8%。

　　As the core solution for short-range wireless transmission, Bluetooth technology achieves stable connection between devices and mobile terminals through the Low Energy Protocol (BLE). The built-in Bluetooth module in the follow-up package can automatically recognize smartphones or tablets within a 3-meter range and establish an encrypted transmission channel. This technology is particularly suitable for home scenarios. After patients independently measure their blood pressure, blood glucose, and other physiological parameters, they can be instantly synchronized to a dedicated app, with a data integrity rate of 99.8%.

　　Wi-Fi直連方案

　　Wi Fi Direct Connection Solution

　　配備雙頻Wi-Fi模塊的隨訪包，支持2.4GHz與5GHz雙通道傳輸。在社區衛生服務中心等固定場所，設備可通過接入局域網直接上傳數據至區域健康信息平臺。該方案單次數據包傳輸速率可達866Mbps，較藍牙提升8倍，尤其適合心電圖等大容量數據的實時回傳。

　　Follow up package equipped with dual band Wi Fi module, supporting dual channel transmission of 2.4GHz and 5GHz. At fixed locations such as community health service centers, devices can directly upload data to the regional health information platform by accessing the local area network. This solution can achieve a single data packet transmission rate of 866Mbps, which is 8 times faster than Bluetooth, and is particularly suitable for real-time transmission of large capacity data such as electrocardiograms.

　　蜂窩網絡覆蓋

　　Cellular network coverage

　　4G/5G模塊的集成使隨訪包具備移動通信能力。在偏遠農村或流動人口管理場景中，設備可脫離中間設備，通過運營商網絡直連云端服務器。某省級慢病管理項目實測顯示，5G網絡環境下數據傳輸延遲低于50ms，滿足遠程會診對實時性的要求。

　　The integration of 4G/5G modules enables the follow-up package to have mobile communication capabilities. In remote rural areas or mobile population management scenarios, devices can be disconnected from intermediate devices and directly connected to cloud servers through operator networks. The actual measurement of a provincial chronic disease management project shows that the data transmission delay in the 5G network environment is less than 50ms, which meets the real-time requirements of remote consultation.

　　云平臺中繼模式

　　Cloud platform relay mode

　　高端隨訪包采用混合傳輸架構，數據首先通過藍牙/Wi-Fi匯聚至邊緣計算網關，經協議轉換后批量上傳至醫療云。這種分級傳輸模式既降低終端功耗，又提升數據吞吐量。某三甲醫院試點數據顯示，該模式使單日數據接入量提升300%。

　　The high-end follow-up package adopts a hybrid transmission architecture. Data is first converged to the edge computing gateway through Bluetooth/Wi Fi, and then uploaded to the medical cloud in batches after protocol conversion. This hierarchical transmission mode not only reduces terminal power consumption but also improves data throughput. According to pilot data from a tertiary hospital, this model has increased daily data access by 300%.

　　二、有線傳輸補充方案

　　2、 Supplementary plan for wired transmission

　　USB物理連接

　　USB physical connection

　　針對無網絡環境或設備初始化場景，隨訪包保留Type-C接口。通過專用數據線連接電腦，可實現數據導出與系統升級。該方案傳輸速率達5Gbps，但需人工干預，主要作為應急備份通道。

　　For scenarios without network or device initialization, the follow-up package retains the Type-C interface. By connecting a dedicated data cable to a computer, data export and system upgrades can be achieved. This solution has a transmission rate of 5Gbps, but requires manual intervention and is mainly used as an emergency backup channel.

　　以太網擴展

　　Ethernet Expansion

　　部分專業級設備配置RJ45網口，可直接接入醫療機構內網。這種硬連接方式通過MAC地址綁定與VLAN隔離，滿足等保2.0三級要求，適用于傳染病房等高安全需求場景。

　　Some professional level equipment is equipped with RJ45 network ports, which can directly connect to the internal network of medical institutions. This hard connection method binds MAC addresses and isolates VLANs, meeting the requirements of Level 3 of the Equal Protection 2.0, and is suitable for high security scenarios such as infectious disease wards.

　　三、傳輸安全保障體系

　　3、 Transmission security guarantee system

　　加密傳輸協議

　　Encryption Transmission Protocol

　　所有無線傳輸均采用AES-256加密，數據包封裝時加入時間戳與設備指紋，防范重放攻擊。某市疾控中心測試表明，該機制可抵御99.9%的網絡竊聽嘗試。

　　All wireless transmissions use AES-256 encryption, and timestamps and device fingerprints are added during packet encapsulation to prevent replay attacks. The testing conducted by a certain city's disease control center shows that this mechanism can resist 99.9% of network eavesdropping attempts.

　　雙因素認證機制

　　Two factor authentication mechanism

　　數據接收端實施設備證書與用戶令牌雙重驗證。當隨訪包首次接入新網絡時，需通過管理平臺授權，并在APP端進行二次確認，確保數據流向可控。

　　The data receiving end implements dual verification of device certificates and user tokens. When the follow-up package is first connected to a new network, it needs to be authorized through the management platform and confirmed twice on the APP to ensure that the data flow is controllable.

　　傳輸質量監控

　　Transmission quality monitoring

　　內置的QoS模塊實時監測信道質量，當檢測到丟包率超過閾值時，自動觸發重傳機制。在地鐵等復雜電磁環境中，該功能使數據完整率維持在95%以上。

　　The built-in QoS module monitors channel quality in real-time and automatically triggers a retransmission mechanism when the packet loss rate exceeds a threshold. In complex electromagnetic environments such as subways, this function maintains a data integrity rate of over 95%.
