1. O&M Management System and Institutional Development
Weak-current system O&M management should establish a three-tier O&M system: Tier 1 O&M — hotel engineering department daily inspection, simple fault handling, and equipment status monitoring; Tier 2 O&M — regional technical support, scheduled maintenance, system optimization, and complex fault handling; Tier 3 O&M — manufacturer or professional service provider deep repair, software upgrades, and system expansion. Management systems should include O&M management manual, operating procedures/SOP, emergency response plans, inspection standards, daily/weekly/monthly/quarterly/annual checklists, equipment ledger management system, and spare parts management system.
2. Daily Inspection and Preventive Maintenance
Daily inspection is divided into five levels: daily, weekly, monthly, quarterly, and annual. Daily inspection content (approximately 30 minutes): BA system interface inspection, checking alarm records and trend charts; equipment room environment inspection (temperature, humidity, UPS status); network core equipment status (indicator lights, CPU, memory, port traffic). Weekly inspection content (approximately 2 hours): camera video quality inspection, access control system log inspection, RCU system online status inspection, server disk space inspection.
3. Fault Classification Handling and Emergency Plans
Fault classification management: Level 1 emergency fault — system paralysis or impact on guest experience; immediate response, on-site within 30 minutes, recovery or activation of backup plan within 2 hours; Level 2 important fault — partial area system abnormality; response within 1 hour, recovery within 4 hours; Level 3 general fault — single-point equipment fault; response within 4 hours, recovery within 24 hours. Typical fault handling process: receive fault report → preliminary diagnosis (remote/phone) → dispatch personnel → on-site troubleshooting → fault localization → repair handling → verification testing → fill in work order → archive analysis.
4. Spare Parts Management and System Upgrades
Spare parts management strategy: critical spare parts warehouse — wearing parts and core components such as DDC controllers, power modules, network modules, sensors, etc.; inventory satisfaction rate ≥95%; regular spare parts such as cameras, card readers, locks, panels, etc., configured at 5% of total equipment count; supplier agreement spare parts — large spare parts such as chiller control modules and VFDs, with rapid supply agreements signed with suppliers for delivery within 24 hours. System upgrade management: software upgrades must be performed during low-load periods, recommended 2:00–5:00 AM; complete backup of configuration files and databases must be made before upgrading.
