Traffic Signal Light Solution (Full Project Lifecycle)
- Receive project inquiry from customer, confirm project location: Ban Mai Mongkol Intersection, Tambon Mae Mo, Lampang, Thailand
- Collect key requirements: intersection type, traffic flow, power supply, control mode, construction period, acceptance standard
- Conduct on-site survey: check road conditions, pipeline layout, pole installation position, foundation environment, lightning protection & grounding conditions
Demand Analysis & Scheme Planning
- Define system configuration: Φ300mm LED traffic signals (red/yellow/green/right-turn green), intelligent signal controller, galvanized steel poles, concrete foundation
- Confirm structural parameters:
○ Galvanized steel poles: Φ4''(4.5mm thick), Φ5''(5.0mm thick), Φ6''(5.0mm thick)
○ Foundation: 1:3:5 concrete, 30×30cm steel base plate (10mm thick), 6mm stiffeners
○ Grounding: Φ16mm×2.4m copper-clad steel ground rod
○ Wiring: Φ2'' RSC conduit to concrete junction box
- Control functions: automatic, manual, yellow flash, all red, phase adjustment, directional control
- Comply with local traffic safety and electrical standards
- Structural design: pole details, foundation plan, section details, grounding layout
- Electrical design: controller cabinet wiring, signal driver circuit, power distribution, interface (Ethernet, USB, RS232)
- Control logic design: phase file, period file, special date file, timing plan
- Output documents: construction drawings, wiring diagrams, BOM list, technical specification

Aging test
Continuous power-on for over 24 hours to ensure stability
Issue factory test report, certificate, and packing list
- Pack products with moisture-proof and shock-proof materials
- Arrange transportation and track logistics
- Customer receives goods, checks quantity and appearance, signs receipt
- Foundation construction: excavation, reinforcement, concrete pouring, pre-embed conduits and grounding rods
- Pole installation: fix poles, connect grounding, fasten base bolts
- System assembly: install signal heads, controller cabinet, wiring and waterproof treatment
- Commissioning: single-light test → phase debugging → full-automatic operation → function verification
- Trial operation: stable running for 3–5 days, record operation log
- Prepare acceptance documents: as-built drawings, test reports, operation manual, warranty certificate
- On-site acceptance: check appearance, function, brightness, response, grounding safety
- Customer confirms qualified and signs acceptance form
- Provide operation training and after-sales support (warranty, maintenance, remote service)
