Introduction
Interpretation of the core content of the standard
As a mandatory public safety industry standard, this standard has established a complete technical framework for the security of urban public buses and trams and stations. Through a three-dimensional collaborative protection system of human prevention, physical prevention, and technical prevention, it focuses on solving key safety issues such as steering wheel grabbing, flammable material monitoring, and station perimeter protection.
Security protection level classification
| Protection objects | Core risks | Compulsory measures | Technical indicators |
|---|---|---|---|
| Driving area | Physical conflict/steering wheel grabbing | Physical isolation + double identification system | Isolation facilities with pressure ≥500N |
| BRT station | Risk of violent terrorism in crowded areas | Platform safety door + intelligent monitoring | Video resolution ≥1920×1080 |
| Charging station area | Electrical fire risk | Dual video surveillance + fire isolation | Image storage ≥ 30 days |
Key points of technical innovation
Flammable liquid monitoring system
For the first time, the standard clearly requires that key lines be equipped with flammable liquid volatiles monitoring and alarm devices, and its technical characteristics include:
- Detection sensitivity: can identify molecules such as gasoline and rosin water
- Response time: ≤3 seconds (splashing scenario)
- False alarm control: eliminate interference from daily items such as shampoo
Typical case: After a city bus group deployed the system on a cross-river route, it successfully warned of two incidents of carrying gasoline on board.
Implementation suggestions
Phase-based construction plan
- Emergency measures phase (within 1 month): complete the renovation of the isolation facilities in the driving area and the deployment of crew managers
- System construction phase (6 months): deploy video surveillance networking platform and station perimeter protection system
- Optimization and improvement phase (1 year): install intelligent analysis modules and improve emergency response mechanisms
Operation and maintenance management requirements
Establish a maintenance system in accordance with the GA 1081 standard, with key guarantees:
- Equipment failure repair time limit: 24 hours
- System timing error: ≤1 second
- Alarm information storage period: ≥90 days
