Introduction

Analysis of the core content of the standard

This standard constructs a three-layer technical architecture including edge computing unit, analysis unit and service platform, and clearly requires:

Technical module	Core function	Performance indicator
Edge computing unit	X-ray video encoding conversion, real-time model calculation	Delay ≤ 200ms, support GB/T 28181 protocol
Analysis unit	Intelligent comparison, event management, image retrieval	Precision rate ≥ 95%, detection rate ≥ 90%
Service platform	Model training, system management, data interaction	Support 1000+ edge nodes concurrently

Detailed explanation of key technical indicators

1. Intelligent analysis performance

The standard requires the system to meet the following requirements: Single frame processing time ≤ 500ms, False positive rate ≤ 5%, Missed positive rate ≤ 10%, and defines a complete performance test method:

Application case: The measured data at a security inspection station in Hangzhou shows that for gun barrel assembly reached 97.3%, with a false alarm rate of only 2.1%, which is significantly better than manual inspection efficiency.

Recommendations for the implementation of the standard

1. Deployment architecture selection

According to clause 9.1 of the standard, it is recommended to adopt a cloud-based collaborative architecture:

• Edge layer: deployed on the security inspection equipment side to achieve real-time initial screening
• Center layer: establish a provincial analysis platform for in-depth analysis

2. Data security requirements

Must comply with the security interaction specifications of GA/T 1788.3, including:

• AES-256 encryption for video stream transmission
• Desensitization of biometric data
• Operation log retention ≥ 180 days

Technology evolution analysis

Compared with the GA/T 1399 standard, this version has the following major breakthroughs:

1. Introduction of Deep learning model Dynamic update mechanism
2. Added real-time processing requirements for X-ray video streams
3. Cleared data connection specifications with GA/T 1400 system
