Introduction

Analysis of CPS integrated interconnection technology architecture

The information-physical fusion system (CPS) integration architecture proposed in this standard includes three core components: protocol wrapper, management shell, and message flow pipeline, and realizes the integration of IT/OT/Internet domains through a layered transformation model.

Technical Dimensions	Traditional Integration Methods	CPS Integration and Interconnection Solutions
Protocol Adaptation	Point-to-point Custom Development	Parameterized Protocol Templates (Supporting 12 Types of Industrial Protocols)
Data Conversion	Hard-coded Mapping	Dynamic Format Conversion Based on Management Shell Model
Message Transmission	Direct Call	Asynchronous Message Queue + Transaction Compensation Mechanism

Key Technology Implementation Requirements

1.

The standard requires that the protocol wrapper must include:

Unique ID: automatically generated according to the service encoding rules
Protocol adaptation template: supports 10 types of protocols such as MQ/HTTP/OPC UA
Management shell model: contains the structured definition of the routing domain (Header) and the data domain (Body)

Application Case: Integration of ERP and MES Systems

An automotive parts company encapsulated the material master data interface of SAP ERP into a standard MQ service through the RFC protocol adapter. The MES system automatically synchronizes the production plan by subscribing to the service, and the integration efficiency is improved by 70%

2. Message Standard

The standard stipulates that the XML message must contain the following structure:

 <Service> <Route> <SourceSysID>02001</SourceSysID> <ServiceID>00010000000100</ServiceID> <SerialNO>2016051727635262123</SerialNO> </Route> <Data> <Control/> <Request>...</Request> </Data> </Service>

Implementation Suggestions

1. Phased Construction Path

Protocol Standardization Phase: Prioritize the adaptation of industrial protocols such as OPC UA and Modbus
Service encapsulation phase: Service-oriented system interfaces such as SCADA and MES
Process orchestration phase: Cross-system business collaboration through message flow pipelines

2. Key points for performance optimization

Control the size of a single message to ≤5MB, and split it if it exceeds 1MB
Control the response time of the intranet to within 5 seconds, and that of the external network to no more than 10 seconds
Deep monitoring of message queues, and setting of automatic compensation mechanism
