Selection and Application of UPS Uninterruptible Power Supply Monitoring System

1, UPS Surveillance System

UPS is a kind of device containing energy storage. Constant voltage and constant frequency uninterruptible power supply with inverter as an important part. It mainly provides uninterrupted power supply for computers, computer networks or other electronic equipment. When the mains power input is normal, the UPS supplies the mains voltage to the load after being regulated. At this time, the UPS is a mains voltage regulator, and at the same time it also recharges the battery . At that time, the UPS immediately supplies 220V AC power to the load by means of inverter conversion to maintain the load and protect the software and hardware of the load from damage.

UPS monitoring system is divided into narrow and broad sense. The UPS monitoring system in the narrow sense refers to a solution for monitoring and managing the operating status of the UPS; the UPS monitoring system in the broad sense refers to not only monitoring and managing the operating status of the UPS itself, but also focusing on the UPS. A comprehensive UPS power supply safety management system for environmental system monitoring, management and control. The UPS monitoring system is developed along with the development of UPS technology and products, and is an important part of the UPS power supply system.

2.Necessity of using UPS monitoring

So, why do you need to monitor UPS? The reason why UPS must be monitored and managed accordingly is actually determined by the limitations of the traditional UPS system itself.

(1) The single machine has a high failure rate and often affects the continuous work of the supported system. Traditional stand-alone UPSs do not have backup lines or emergency plans. All power supply lines are single lines. Once a problem occurs, power supply interruption is inevitable. Once this situation occurs and further spreads, if it is not dealt with in a timely manner, it is likely to cause irreparable huge losses.

(2) Poor scalability. The configuration of traditional UPS is fixed and cannot be upgraded. In the event of an information system upgrade that requires an increase in power supply capacity, you can only purchase a new UPS. In addition, the UPS power supply system itself can only guarantee the safety of power supply, but it has no power to monitor and manage the power environment.

(3) Management is difficult. There is no difference in function and use of all batteries or battery packs. When one of the batteries fails, the UPS cannot shut down and replace it in a timely manner. It can only report a system failure and then replace it manually by the management staff. In addition, most domestic small and medium-sized computer rooms do not have 24-hour personnel on duty. Generally, inspection methods are used. Hidden dangers cannot be found immediately. There are hidden safety hazards during non-working hours, holidays, etc., and related management personnel cannot know and deal with them immediately.

(4) High maintenance costs. The maintenance of the traditional UPS system is a highly technical task. For ordinary battery replacement, it is also required to be performed by professional technicians. Users generally do not replace it by themselves; Subsequent maintenance brings huge transportation and time costs.

In addition, the automatic and standardized management of UPS is a key step to truly realize the safety and reliability of the UPS power supply system, and it is also an important content to achieve the unattended modern computer room construction goal of the computer room.

3.How to choose UPS monitoring system

Due to the relatively lagging development of the UPS monitoring market, for most UPS users, there are limited ways to obtain information about the UPS monitoring system, and the indicators and technologies used by the UPS monitoring system lack a comprehensive objective. Understanding. Therefore, for many UPS users, how to purchase a UPS monitoring system that suits their needs is really a headache. So what factors should users consider when purchasing a UPS monitoring system?

3.1 Application environment

At present, UPS has been widely used in various industries, and each industry's requirements for UPS are also focused. For example, the UPS used by banks has a larger power, capacity, or anti-interference ability than the UPS used by general SMEs. Difference, and UPS's working environment is more unique. Therefore, the UPS monitoring system selection should also be targeted. At present, many UPS monitoring systems on the market, such as the comprehensive power management environment solution for small and medium computer rooms (for small and medium computer rooms), integrated self-service banking power environment monitoring and management solution (for self-service banks), and UPS short message monitoring solutions. (For applications without internet / Ethernet networks or high cost of setting up networks) and other departments are developed for different application environments. Therefore, in the selection of the UPS monitoring system, the application environment of the system must be clarified first, so that a suitable UPS monitoring system can be selected, and only the UPS monitoring system that matches the application environment can have sufficient efficiency of state detection and fault alarm.
