WISE-PaaS/SRP Services
Contents
OVERVIEW
- API Management
Adopt Azure API Management/Open-source (WSO2) to integrate various SRP services API.
- Common Service APIs/Lib
Basic Account/Device/Group/Role operation APIs, including Add/Edit/Delete/Search/Advance Search WISE-PaaS administration information (Product Support, version, capability…etc.)
- Custom/SRP Service
RMM/IMM/OTA/SCADA self-service APIs
- Common Data Workers
Including device basic information and sensor data from broker. (Common MQTT Topic) For structure info (device Info) store into PostgreSQL For non-structure (sensor Info) store into MongoDB/DocumentDB/...etc.
- Custom/SRP Data Workers
Process RMM/IMM/OTA/SCADA self-MQTT topic message and store into self-database (RMM/IMM/OTASCADA DB)
- Message Broker (RabbitMQ)
Adopt RabbitMQ as default cluster broker, and plugin MQTT as communication protocol.
- Device Agent
Define common MQTT topic handshake message and custom/SRP topic format.
- Database (SQL/NoSQL)
PostgreSQL as default relation database and including Common/RMM /SCADA/IMM/etc. MongoDB/DoucmentDB for sensor information collect.
COMMON DATABASE SCHEME
Concept & Design Rules
- Device belong to multi-groups or not to any group.
- Each account have non or multi-groups.
- Each group must belong to someone account.
- Group of group (1-3 Levels)
- Each account must belong to someone role.
Common Database Scheme

DEVICE CONNECTIVITY
- Adopt open source RabbitMQ on server side to support both AMQP and MQTT protocol.
- Transportation supports MQTT, AMQP and HTTP (Websocket)
- Define the common communication APIs for our WISE Agent, we called WISE Connector APIs
- Implement the WISE Connector APIs with different communication protocol.
- WISE Agent can link different communication protocol at compile time.
- Supports secured connection (TLS/SSL) with anonymous and authenticated account
Message Topics
- MQTT Topic Define
- From Server to Agent:
/wisepaas/<product>/<agentId>/<function>ack
- From Server to Agent:
- From Agent to Server:
/wisepaas/<product>/<agentId>/<function>req
- Preserved Topic for Common use
- Agent Registration Topic: /wisepaas/device/<agentId>/agentinfoack
- Will Message Topic: /wisepaas/device/<agentId>/willmessage Or /wisepaas/device/<serverId>/willmessage
- Command Topic: /wisepaas/device/<agentId>/agentactionreq
- Response Topic: /wisepaas/device/<agentId>/agentactionack
- Report Data Topic: /wisepaas/device/<agentId>/devinfoack
- Custom Topic Sample
- Custom Topic for power ON/OFF:
Server send command with topic: /wisepaas/custom/<agentId>/powerctrlreq
Agent send response with topic: /wisepaas/custom/<agentId>/powerctrlack
Handshake Sequence
- Normal sign in and sign out sequence:
- Agent lost connection with will message sequence:
- Server lost connection with will message sequence:
Data Format
- Basic JSON Format
- IPSO Format (Application Framework)
