1,000-lamp project modelA large lighting site can be divided by road, cabinet, branch circuit and maintenance area.
Grouped strategiesSchedules, sunrise and sunset policies and holiday modes can be configured by group.
Energy acquisitionVoltage, current, power and energy data help identify load changes and abnormal circuits.
Maintenance visibilityRemote status, alarms and logs reduce blind inspection work for distributed lighting assets.

Application Model

The content is organized for engineering companies, system integrators and project owners who need to understand device roles, data flow and maintenance value.

Cabinet-based controlRelay controllers can be installed by lighting cabinet or branch circuit to support remote switching and batch operation.
Energy monitoring loopMeters and current acquisition modules can provide circuit-level energy data for comparison, reports and fault judgment.
Operation strategyLighting schedules can be aligned with road sections, seasons, holidays and actual project requirements.

System Architecture and Product Combination

Controllers handle switching and linkage, sensors provide field data, meters collect energy information, gateways handle communication access, and the platform supports schedules, alarms, logs and remote maintenance.

Network relay controllers for cabinet and branch circuit controlUsed as part of the project combination for control, acquisition, communication, platform management or maintenance records.
Three-phase meters and current acquisition modules for energy monitoringUsed as part of the project combination for control, acquisition, communication, platform management or maintenance records.
IoT platform for grouped schedules and remote logsUsed as part of the project combination for control, acquisition, communication, platform management or maintenance records.
Protocol integration for customer platform accessUsed as part of the project combination for control, acquisition, communication, platform management or maintenance records.

Operation Strategy and Data Value

Project value is usually measured through circuit grouping, device status visibility, alarm response, remote maintenance records, energy trend comparison and fewer unnecessary field inspections. Actual results depend on site scale, equipment power, communication conditions and operation strategy.

Selection FAQ

Can street lighting use sunrise and sunset schedules?Lighting projects can use fixed schedules, sunrise and sunset policies and grouped operation according to road section and cabinet configuration.
Can the solution be deployed in phases?Yes. Projects can start from key circuits, sensor points or meters and then expand to more areas, devices and platform functions.
Does it support private deployment?The platform and device access method can be planned around cloud use, project deployment or private deployment requirements.
How should products be selected?Selection should follow the field object, signal type, communication condition, cabinet layout, platform requirement and maintenance workflow.

Estimated 30% Energy-Saving Target

For lighting, air-conditioning and fresh-air systems with area-based control, schedules, scene linkage and energy monitoring, around 30% can be used as a project optimization target for feasibility calculation. This wording applies to sites with manual switching, long full-load operation, missing holiday schedules or unattended areas running for unnecessary periods; actual results depend on equipment power, operating hours, circuit grouping and strategy execution.

30% targetUsed as a planning target for strategy optimization and reviewed with project baseline data.
Area and time controlReduce unnecessary operation by room, area, circuit, schedule and holiday mode.
Energy feedbackUse meters and acquisition modules to compare energy trends before and after strategy changes.
Project boundaryThe final result depends on site scale, equipment load, baseline operation and maintenance rules.
