The reliability of the data center power supply system is critical。No matter how sophisticated the IT equipment is or how superior the function of the system is, once the power goes out, no matter how good the system is, it will not work. Therefore, the importance of equipment maintenance in operation cannot be ignored. The classification and analysis of some matters of UPS in terms of human failure：
1. Cognitive errors
The emergence of such situations is mainly due to the lack of basic theoretical knowledge of maintainers。
2. Equipment hidden dangers were not discovered in time
The damage process of the battery is caused by gradual accumulation. For example, some devices will age or fail early during operation. But some happen instantaneously, it was available yesterday, but it is broken today。If the maintenance personnel do not find the hidden danger in time and take corresponding measures, the UPS failure will be caused.
3. Failure due to improper equipment maintenance
Although the periodic maintenance content of UPS is less, but these are very necessary，Moreover, these maintenances must have a set of strict procedures. Regular maintenance of equipment not as required is an important cause of failure.
4. Failure caused by improper use environment
This type of failure is caused by the user not paying attention to the environment in which the device is used。For example, place the equipment in a warehouse without air conditioning and the warehouse is not ventilated，Or randomly placed in corridors, dripping basements, and powder-flying workshops。
A set of scientific and effective methods should be formulated and strictly followed for the maintenance of UPS, and there are many drawbacks in the way of manual maintenance, such as：
1. The voltage between the battery rack and the battery pack is very high, making manual maintenance unsafe
2. The user cannot grasp the real-time data of the operation of the battery pack and the health status of the battery in real time.
3. There are hundreds or thousands of batteries in the computer room. It takes a long time to test once, the labor cost is high, and the time is long.
Relat battery online monitoring system is an online automatic battery performance testing and monitoring system, Adopting a single module structure, it has the advantages of flexible and convenient installation, high measurement accuracy, and high system security. Install a battery online monitoring system for the battery pack, Real-time online monitoring of battery voltage, internal resistance, pole temperature, leaking fluid, group voltage, group current and other important parameters, Immediately alarm when a parameter is found to be abnormal, which can prompt the maintainer to find problems or potential hidden dangers in time, To deal with it in time, so that the failure rate of the UPS is greatly reduced, and it can truly provide a safe and reliable clean power supply for the equipment without interruption.
