      The traditional maintenance and management of AC power UPS and DC power include:

① Daily appearance inspection, regular replacement of batteries, filter capacitors, fans and other vulnerable parts, and battery activation during major repairs;

② Transform or adopt replacement equipment and use advanced tools to test battery performance.These management methods result in high investment costs for enterprises, heavy workload for maintenance personnel, difficulty in real-time monitoring of equipment operation status and key data, and low ability to prevent equipment accidents. The current status of AC UPS and DC power supply, as well as the existing network scale of the enterprise, should be reasonably configured based on equipment functions and importance.

The following are the system application precautions for AC UPS and DC power supply:

1. Determine the network architecture plan, that is, whether it is necessary for the enterprise to establish a complete network system or build on the existing network foundation, and achieve complete and independent online maintenance and management for individual battery packs.

2. Taking the online management system as the core, supplemented by necessary manual testing, can reduce management costs. Large stations and key equipment directly adopt a complete system, while small stations and individual UPS are processed by backend machines to form a comprehensive maintenance management system.

3. Some UPS and DC power supplies already have multiple management functions, such as status parameters, status recording, alarms, etc. Reasonable configuration not only reduces development costs, but also reduces the hidden dangers of faults caused by excessive lines.

4. The maintenance management system for AC UPS and DC power supply only monitors, and it is recommended that the issuance of control commands (such as fault handling, switching, activation, etc.) be manually implemented.

5. After the system is established, monitoring stations can be set up in manned areas, and operators can monitor the operation status 24/7. Maintenance personnel should regularly check and manage it.

6. To reserve interfaces and protocols for compatibility with other systems, the upper level management of the system can also be built on the existing website of the enterprise.

7. It is recommended to separate the state management system from the process control or execution system, paying attention to their independence and not interfering with each other.

8. After the system is established, there should be a work system and management mechanism to ensure normal use.The UPS and DC power online maintenance management system ensures the safety and stable production of enterprises, transforms traditional maintenance into condition based maintenance, reduces a lot of maintenance costs, and increases enterprise benefits.
