Introduction
Analysis of Ecode Identification Middleware Technical Architecture
| Subsystem | Core Module | Technical Implementation |
|---|---|---|
| Configuration Subsystem | Log Management/Permission Control/Security Management/Abnormal Alarm | Four-level log classification (DEBUG-INFO-ERROR-WARN), RBAC permission model |
| Service Subsystem | Device Management/Data Processing/Message Passing/Application Interface | Support access to heterogeneous devices such as RFID readers and NFC devices |
| Application Development Subsystem | Development Interface/Development Tools/Development Environment | Multi-language SDK (C/Java/C#), cross-platform support (Windows/Linux) |
Key Points for Implementation of Core Functions
6.1.3 Security Management Mechanism
The standard requires the implementation of three-in-one security protection:
1) Audit tracking: record user operation timestamps, sensitive data access, etc.
2) Transaction transmission: use a two-phase commit protocol to ensure the integrity of QR code data
3) Current limiting control: the default setting is ≤100 requests per second for a single IP
7.4 Performance Benchmark Indicators
| Indicator Type | Test conditions | Standard requirements |
|---|---|---|
| Data writing efficiency | UHF RFID tag | ≥200 tags/second |
| Service response time | 100 concurrent requests | ≤500ms |
Standard evolution and industrial application
This standard and GB/T31866 together constitute the Internet of Things identification technology system, among which the middleware design:
1) 2017 version: For the first time, it stipulates the storage format of Ecode in barcode/RFID
2) 2020 version: Adds distributed architecture support and NFC device compatibility requirements
Typical case: A smart warehousing system uses middleware to achieve unified processing of QR code and RFID tag data, increasing throughput by 40%
Implementation suggestions
- During the development phase, priority should be given to implementing the RFID tag writing specification specified in GB/T35421-2017
- During deployment, it is recommended to use the Docker containerization solution to ensure the 99.9% availability required by 7.1
- Performance tuning focuses on the RabbitMQ cluster configuration of the message module
