Routine Basic Inspections
For standard environments such as commercial districts and public plazas, a basic inspection is recommended once a month to check for surface dust and the condition of LED pixels. In harsh environments-such as coastal or industrial areas-inspection frequency should be increased to once every two weeks, with a focus on checking for corrosion and the integrity of waterproofing.
In-Depth Maintenance Schedule
Comprehensive maintenance should be performed every three months in standard environments, involving the removal of internal dust accumulation and checks on wiring and waterproofing structures. In harsh environments, in-depth maintenance is required every one to two months, with additional targeted inspections conducted following heavy rainstorms or typhoons.
Specialized Component Inspections
Power supply and signal cable connections should be inspected quarterly; waterproof sealing structures every six months; and the stability of the steel structure verified annually. Additionally, a full-system inspection by professional technicians should be scheduled at least once a year.
