Introduction
Interpretation of the core content of the standard
This standard constructs a standardized coding system for subscription identification in the video image control system, and realizes full process traceability through a 33-bit fixed-length number:
| Level | Number of digits | Coding content | Specification basis |
|---|---|---|---|
| First layer | 1-12 digits | Public security agency organization code | GA/T 380 |
| Second layer | 13-14 digits | Service subtype (01 control/02 alarm/03 subscription/04 notification) | Clause 3.b of this standard |
| Layer 3 | 15-28 digits | YYYYMMDDhhmmss timestamp | ISO 8601 extension |
| Layer 4 | 29-33 digits | Serial number starting from 00001 | Clause 3.d of this standard |
Technology Evolution Analysis
This encoding rule reflects three major technological breakthroughs:
- Spatiotemporal correlation: Time coding accurate to seconds is used to achieve spatiotemporal matching between control instructions and video data
- Business scalability: The "99" subtype is reserved to provide expansion space for future new intelligent analysis services
- Global uniqueness: The combination of organization code + timestamp + serial number ensures that the identifier is unique across the entire network
Application Example
A city public security bureau (organization code 123456789012) issued a vehicle control instruction at 14:30:25 on June 15, 2023. The instruction code is:
123456789012012023061514302500001
Implementation Suggestions
- A code generation verification module should be established during system development to ensure that the timestamp is synchronized with the server clock
- It is recommended to create an independent index field for each layer of code in database design
- Code integrity must be maintained during cross-system transmission, and truncation or transcoding is prohibited
