IoT platform, the ability to open
2.1 Unlock Things platform, met with OceanConnect
Things platform challenges.
The first challenge: a new line of business cycle length
can only access its own platform, the application of severe fragmentation, the product development cycle is long, slow market
The second challenge: a different, difficult to integrate standard
terminal manufacturers and more sensors, a number of communication protocols, standards are not unified, integrated difficulty
The third challenge: complex network
complex was networking environment, multi-network type, terminal manufacturers to develop many protocols requires adaptation, manufacturers move to higher field threshold and other things
IoT management platform coupled
action:
1. decoupled access terminal, an open terminal access, terminal manufacturers to reduce development costs
2. Capacity open, extended open service applications, to provide a unified interface to facilitate the manufacturers to develop API Application
Protocol:
1.MQTT (Mssage Queuing telemetry transport) (message Queuing telemetry transport)
the IBM developed based messaging protocol and TCP / IP of
advantages: the protocol simple, lightweight, messages may be as short as 2 bytes, the hardware configuration of the terminal requires a low
terminal connected clients:
long connection (heartbeat keep-alive mechanism)
Benefits: reduce overhead chain re-built to support real-time notification message, there is a wealth of push content
disadvantages: is not conducive to entering sleep mode, the device consumes more power
2.CoAP (Constrained Application Protocol) (restricted application protocol)
suitable for the communication resource constrained device, NB-IoT / LoRa
Compare the MQTT, the CoAP
3.HTTP
things internet
1. The facilities management platform (the DMP: Device Management Platform)
2. Connection Management Platform (the CMP: Connectivity Management Platform)
3. Enable Application Platform (the AEP: Enablement the Application Platform)
4. Business analysis platform (BAP: Business Analytics platform)
2.2 Interpretation platform features, and OceanConnecion friend
OceanConnection: Huawei based networking, big data, cloud computing technology to create an open environment
the application layer: a service enabling layer, a connection layer device
Service enabling layer: API open management, data management, rules engines
Device connection layer: a unified access capabilities, assets and equipment management, SIM card connector management
IoT connection with the functions of business management platform
device management
include gateway management, SP Portal, direct management device
device access authentication
of terminal equipment including the identity of the gateway for authentication to prevent unauthorized access of illegal equipment
rules engine
and more used in household equipment
Portal management
includes SP Portal, OSS Portal, OperationPortal
SP Portal: Developers for the SP user application management (registration NA), asset management, reporting (assets related reports under SP user) management, rule engine (SP editing application rules) management software (upgrade assets)
Operation Portal: Operations personnel management platform for all SP user query reports all access OceanConnect assets
OSS Portal: divided into the business side with the management side
of business face: for maintenance personnel NE docking parameter configuration, maintenance capabilities, data backup services, License management
administration faces: for maintenance personnel to install IoT platform, monitoring, upgrades, data backup services management
Platform Features:
2.3 familiar with the business processes, accompanied with OceaConnection
Architecture:
IOCM: IoT is the most important module connection management module, platform to support connection state management and control command forwarding
DM Server: Device Management Server
Rule Engine: Rules Engine
Mongo DB: database of user information
CIG: cloud gateway
Business Process:
1. north to the registration process
to landing north, authentication
2. The service provisioning process
application platform id password Update details IoT devices into account Mongo DB must first open an account otherwise illegal
3. south registration process
initiated registration, authentication based on the authentication it, update status information, notification equipment line, the implementation of a registration, authentication is executed multiple times
4. The South reported the message
to meet the conditions, reporting, whether stored in the database, whether to report server, different devices in different reporting mechanisms for periodic reporting, event of the fashion pack
5. Under the control message is sent
forward to IOt terminal, whether the message, if the server needs to be reported, is not always online
