Beijing Winter Olympics the Venue Lightning Protection Safety
Using FS Lightning Current Monitoring Monitors, FSS Smart SPDs, FL Transient Current Monitors and FG Smart Gateways, FEXLINK provides 7×24h online monitoring of the sports venue's distribution system and lightning protection facilities, with real-time sensing of lightning events, SPD status and lightning protection system health, ensuring stable operation of electrical and lightning protection systems during large events.
01 · BACKGROUND
Customer Background
Enterprise Type
A sports venue operation enterprise, responsible for large sports event venue construction and operation, undertaking international event assurance tasks, with very high safe operation standards.
Enterprise Scale: Hazard warning
Venue Scale
The sports venue contains a main stadium, training hall, auxiliary service facilities and other multi-venues. The distribution system is complex, power load fluctuates greatly, and during event assurance periods, power supply reliability requirements are very high.
Venue Count / Capacity: Online inspection
Industry Position
International event venue, must strictly comply with GB 50057 "Design Code for Protection of Buildings Against Lightning" and JGJ 352 "Electrical Design Code for Sports Buildings" and other standards. Lightning safety is the core of event assurance.
Compliance Standard: GB 50057 / JGJ 352
02 · CHALLENGES
Business Challenges
Mountain Venue: Lightning Frequent, Lightning Risk High
The venue is located in a mountain area, with many lightning days and high lightning strike intensity. The venue's metal roof and electrical system withstand direct lightning and induced lightning strike risks that are significant. During event assurance periods, lightning events have a major impact.
SPD Status Without Online Monitoring, Hazards Hard to Sense
Venue distribution cabinet SPDs have long-term lightning strike shock degradation and failure risks. Traditional SPDs lack online monitoring capability and cannot provide warnings after faults, which may affect event power supply reliability.
Event Assurance Period: Manual Inspection High Pressure
During event assurance periods, high-frequency inspection of distribution cabinets and lightning protection facilities is required. Manual inspection labor investment is high and efficiency is limited, making it hard to meet the real-time and full-coverage requirements of event assurance.
Lightning Event Lacks Complete Data Record
After lightning events, there is a lack of complete continuous data on lightning current amplitude, polarity, and waveform, which cannot support lightning impact assessment, equipment damage analysis, or insurance claim evidence.

Note: Product quantities follow the point-based configuration principle; final quantities are subject to site survey and the implementation plan.
Network Topology
Sensing Layer: FS Lightning Current Monitoring Monitor Deployed at Venue Lightning Rod Downlead Point, FSS Smart SPD Deployed at Venue Distribution Cabinet Power Inlet, FL Transient Current Monitor Deployed at Key Power Circuit SPD Downstream, Cover Lightning Monitoring, SPD Monitoring, Surge Current Monitoring Three Major Dimensions.
Network Layer: Each sensing terminal connects via RS485 bus (Modbus-RTU protocol) to a nearby FG Smart Gateway. The FG Gateway uploads via the venue optical fiber private network / 4G cellular network uplink to the venue operator company's in-grid network. Key nodes support dual-link redundant backup to ensure data transmission reliability during events.
Platform Layer: Data aggregates to the FEXLINK Cloud Platform (privately deployed at the venue data center), providing web & mobile visualization dashboards, lightning event real-time alarms, a historical lightning database, compliance report auto-generation, multi-role permission management and other functions, and supporting event assurance command center large-screen display.
Integration Layer: The cloud platform integrates with the venue's existing BAS building automation system, security command system, and event assurance command system via standard REST API / Modbus TCP protocols, achieving lightning event linked alarms and emergency command coordination.
