Control by cabinet and circuit
Group roadside and park lighting circuits so switching and inspection can follow the cabinet structure.
A road lighting network needs different schedules for different roads and seasons. Organize cabinets, branch circuits and lamp groups together so remote switching, sunrise and sunset timing, energy readings and maintenance records follow the same map.
Cabinet-level relay control and sunrise/sunset schedules work together for road sections that need different operating hours.
Group roadside and park lighting circuits so switching and inspection can follow the cabinet structure.
Set location-based sunrise and sunset actions and offsets for lighting periods that change through the year.
The content is organized for engineering companies, system integrators and project owners who need to understand device roles, data flow and maintenance value.
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.
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.
Build a road-section, cabinet and circuit hierarchy for parks, campuses and scenic areas, grouping main roads, side roads, parking and landscape lighting separately. Install controllers at distribution points with Ethernet or 4G access and local inputs for authorized operation. A circuit-purpose and service-location register gives each batch command a clear scope and supports inspection along the distribution hierarchy.
Use sunrise/sunset schedules with project offsets for outdoor switching, supplemented by operating and duty periods where areas remain in use. Group reduced night operation by road purpose while retaining required access lighting, and use separate scenes for festivals or events. Tie tasks to device groups and effective dates, defining how manual extensions return to normal schedules.
Add current and energy acquisition by cabinet or priority circuit and compare load changes with lighting plans. Offline devices, missing current after an on command or continuing demand after switch-off guide inspection of contactors and fixtures. Keep road scope, fixture count and operating periods consistent in comparisons, retaining repair and schedule changes for ongoing operating review.
Cabinet- and circuit-level control and metering can be implemented first. Further fixture-level subdivision depends on existing wiring and the management objective.
Configure location and project offsets, then combine them with road usage and access-lighting needs in the group policy.

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.
