STSYSTEMPLC is engineered as a city-infrastructure operating layer — not merely a lighting network. A true “global IoT lighting center” must deliver three governed outcomes simultaneously: measurable energy savings, road & public safety, and value-added services that create operational ROI beyond electricity reduction.

Safety lighting + Harmonized lighting + Charming city lighting

• Safety lighting: extreme-weather policies (storm/fog/snow) + road-class governance + traceable execution.
• Harmonized lighting: comfort & glare discipline with adaptive CCT and scene control.
• Charming city lighting: curated scenes for civic areas and events while maintaining compliance targets.
• City public safety: abnormal events, outage patterns, cabinet alarms, coordinated response readiness.

Three mandatory operating layers (no shortcuts)

• Policy & governance (Server): schedules, scenes, audit trail, reporting, integration APIs.
• Continuity anchor (CH-800): feeder/cabinet intelligence, resilience, event governance, segment control.
• Lamp-level execution (SLC810/SLC910): telemetry, dimming, sensor linkage, per-lamp enforcement.

Hybrid PLC + LoRa — communication without obstacles in complex / aging city power lines

• Urban feeders are harsh: noise, branching, transformer barriers, legacy wiring, topology drift.
• PLC scales economically via powerlines; LoRa adds robust paths and transformer-crossing capability.
• Hybrid redundancy preserves continuity: when one channel degrades, the other keeps command stable — critical for safety-lighting governance.

Adaptive CCT 2700K↔6000K — extreme-weather safety lighting solution

• Under extreme weather (heavy rain / heavy snow / dense fog), the city enters a governed safety-lighting mode prioritizing visibility, contrast, and glare comfort.
• Road-class driven + sensor-triggered + traceable logs for EPC / municipal review.
• Delivers energy efficiency + safety + harmonized / charming lighting — not decorative lighting.

O&M workflow ROI (value-added service, not only energy)

• City map visibility for lamp/cabinet status, alarms, and work orders — accurate dispatch.
• Cabinet intelligence: grid failures, cable breakages, leakages, door events, outages, anomalies.
• Reduce patrol loops; improve closure efficiency; logs ready for audit/training.

Offline autonomy = public safety continuity

• When internet disconnects, CH-800 continues stable operation using stored schedules and profiles.
• Astronomical calendar logic supports autonomy without external intervention.
• Continuity is treated as a safety requirement under STSYSTEMPLC governance.

Measured savings (evidence)

• Daily / monthly / yearly consumption & saving reports (cabinet / district / city).
• Target dimming schedules + motion/ambient strategies for maximum optimization.
• KPI pack: kWh, CO₂, uptime, MTTR, dispatch efficiency, patrol reduction.

Governed safety lighting (enforced)

• Road-class policies: highway, tunnel approaches, underpasses, parking, residential, civic areas.
• Extreme-weather modes: storm / fog / snow — safety lighting with glare discipline.
• Traceable changes: policy execution logs suitable for municipal / EPC review.

STSYSTEMPLC turns the lighting grid into a city service carrier layer: operational ROI, safer streets, and integrated city management — not only electricity reduction.

Third-party platform interoperability

• Open protocol and integration readiness with smart city and municipal platforms.
• Unified governance: lighting + sensor networking + assets under one command plane.
• Cloud or sovereign on-prem deployment for government security requirements.

mmWave radar + video integrated unit (traffic optimization)

• Traffic perception enhancement: flow detection, abnormal-event cues, decision support.
• Coordinated response: safety modes, emergency cues, targeted scene control.
• Designed as an add-on service layer powered by always-on lighting infrastructure.

Industrial-grade discipline (continuous duty)

• Designed for continuous duty cycles, harsh outdoor environments, infrastructure-class reliability.
• Cabinet intelligence as the reliability anchor: continuity + monitoring + governed operation.
• Audit-friendly engineering discipline approaching a military-grade reliability mindset.

Brand & delivery (STSYSTEMPLC)

• STSYSTEMPLC naming is carried across spec packs, dashboards, governance documentation, and training.
• OEM-delivered infrastructure-grade cases supported via controlled evidence pack upon request.
• Training + handover packages support operators and tender committees.
