  • 2016 嵌入式技術論壇 : 智慧系統與智慧自動化




    2016嵌入式技術論壇 展現智能感知的物聯網應用新契機

    DIGITIMES於1月19日於六福皇宮舉辦「2016嵌入式技術論壇」,上午場邀集DIGITIMES研究中心、超微(AMD)、宜鼎(InnoDisk)、研華(Advantech)主講IoT的市場變革與機會、感知運算、儲存創新與主動式數據管理的實現。

    下 午場分為兩個主軸,「物聯網裝置開發應用」與「工業控制嵌入式系統設計與應用」,分別由超微(AMD)、台大電機系教授、酷比令與GHOSTA等產學代 表,就開源技術、嵌入式技術發展、物聯網產品從概念到成品的實際案例做分享;以及由台大機械系教授、ABB(艾波比)、立達與睿陽創新等產學代表,就智慧 機器人與物聯網、工業機器人市場發展、智慧機器人的軟硬整合與教育用機器人進行說明。

    由於活動議題瞄準當前最新技術與應用,吸引滿座學員參加,台上演說精彩,台下學員發言踴躍,在2016伊始率先為智慧化嵌入式技術發展與應用熱烈揭開序幕。

    IoT火熱力抗景氣寒風  產業界面對面技術交流

    「2016 嵌入式技術論壇」現場,超微(AMD)攤位展示了全方位的x86嵌入式處理器解決方案,秀出臉部辨識技術的互動應用,同時陳列其合作夥伴們以AMD嵌入式 SOC所研發的各式產品,包括博奕機、盒型電腦(Box PC)、IoT閘道器、網路儲存裝置(NAS)、工業電腦以及各種嵌入式主機板等等。

    儲 存解決方案供應商宜鼎國際(Innodisk),在攤位展示M.2介面設計的儲存產品解決方案,包含M2DOM磁碟模組(安插於宜鼎專利的附銅柱直立插 槽,節省最多90%面積),有PCIe介面的P30、SATA介面的S20/S30,以及USB 3.0的U30系列。另外也展示M2DOM背板(Braket)、轉接板以及直立M.2插槽。

    工業電腦領導製造商研華 (Advantech),於攤位展示了可連接RS232/422/485工控設備或感測器的控制器式閘道器,內建WISE Agency軟體、透過Ethernet/Wi-Fi/3&4G網路匯集數據的電腦式閘道器,並藉由Wise-PaaS/RMM連接到Linux 或Microsoft Azure等雲平台的主動式數據管理架構,作為協助客戶從工業2.0升級到工業4.0的實踐。


    研華技術人員正解說其主動式數據管理的IoT應用架構的運作原理。

  • 淺論MQTT通訊協定

    MQTT 作為MQ遙測的前身,是為了物聯網環境而設計的發佈/訂閱模式消息傳輸協定,它所需要的網路頻寬低也因此它能在受限的環境中,如機器與機器的通信(M2M),讓用戶端使用最少的硬體資源,達到傳送大量訊息的需求。

    About MQTT

    In IoT applications, devices often must communicate with each other (D2D). Device data is then must be collected and sent to the server infrastructure (D2S). That The server infrastructure has to share device data (S2S), possibly providing it back to devices, to analysis programs, or to people. The communication protocols can be described in this framework as:
    • MQTT: a protocol for collecting device data and communicating it to servers (D2S)
    • XMPP: a protocol best for connecting devices to people, a special case of the D2S pattern, since people are connected to the servers
    • DDS: a fast bus for integrating intelligent machines (D2D)
    • AMQP: a queuing system designed to connect servers to each other (S2S)

    MQTT(MQTT (formerly MQ Telemetry Transport) is a publish-subscribe based "light weight" IoT communication protocol for use on top of the TCP/IP protocol. The publish-subscribe messaging pattern requires a message broker. The broker is responsible for distributing messages to interested clients based on the topic of a message.

    MQTT has the following properties :properties:
    1. Based on TCP/IP for basic network connection
    2. Small code foot print
    3. Three different message service qualities
    a. “At most once”
    b. “At least once”
    c. “ExaclyExactly once”
    4. 2- byte header to reduce package transfer loading
    5. It has “LLast ast will and testament” to notifiesy client ifwhen connection is lost connection.
    6. Provides Publishpublish/-Subscribe subscribe structure to provide one- to- many message sharing.

    Publisher is the source of the message, it which will passes data to Topic, and Subscriber will registers for in Topic to get Topic data form Topic.
    So when , if some a Publisher sent sends a message to topicTopic, all registered Subscribers registered for that Topic will get this that message.

    Based on these properties, especially “Small small code foot print” and “Publishpublish-/sSubscribe structure”, WISE-PaaS/RMM uses MQTT as the communication protocol to connect between agents(agents (gateway/devices device side) and servers(servers (back-end/cloud side). On the device side, the agent will collect data with different structures or protocols, and transfer it to MQTT. After this process, device data from devices will hasve the same form and be is kept in the WISE-PaaS/RMM server database of WISE-PaaS/RMM server. The IoT developer can create their applications based on WISE-PaaS server web-services(services (RESTful API).
