Editor: Huabao Golden Samurai ups power

1. Project background

　　 A factory computer room operation and maintenance personnel expressed that they hope to remotely and centrally monitor the UPS power supplies and their batteries in the three computer rooms, and keep abreast of the real-time operating status and abnormal situation alarms of the UPS and their batteries in each computer room at any time.

　　1.1. User equipment overview:

　　Computer room①: 1 Golden Samurai UPS power supply and 48 12V batteries (1 set)

　　Computer room ②: 1 Golden Samurai UPS power supply and 24 12V batteries (1 set)

　　Computer room ③: 1 imported brand UPS and 48 12V batteries (1 set)

　　1.2, user requirements

Perform remote centralized monitoring of UPS power supplies and batteries in 3 computer rooms, real-time viewing of the operating conditions of UPS power supplies and batteries in each computer room, and timely alarm notification in the event of abnormal conditions such as mains power failure or low battery voltage .

　　1.3, user problems

1. The computer room and equipment are scattered, the cost of dispatching personnel is high and the management is difficult.

　　 2. It is impossible to know the UPS power supply of each computer room and the operating status of each battery in real time.

　　3. There is no good management method, and there is insufficient understanding of the operation of the battery pack.

　　4. There is an abnormal situation such as a mains power outage, and there is no alarm notification, and there is a big safety risk.

　　 5. There is no abnormal history record of UPS power supply and battery, so it is difficult to analyze the operating status of UPS and its battery and the cause of failure.

　　二、Solution　　

According to the needs of users, combined with the actual situation of the computer room and equipment. In order to ensure the efficient operation, maintenance and management of the UPS power supply and storage battery in the user's computer room, multiple online centralized monitoring and warning solutions for the UPS power supply and storage battery in the computer room have been selected.

Through the monitoring system platform, users can remotely view the input/output, load and other conditions of each UPS power supply and the battery voltage and current of each set of batteries in real time and intelligently analyze the use of the monitored batteries. . Separate charging and discharging detection through the current sensor, accurately grasp the battery charging and discharging degree, and can automatically judge according to different upper and lower limits and average deviation set by the user. When an abnormal situation occurs, an alarm can be given through SMS, voice, local sound and light, etc.

　　 Three, program advantages

　　1. Users can remotely view the voltage, current, temperature, load, input/output voltage, input/output frequency and other parameters and real-time status of any UPS power supply in any computer room through the PMcenter centralized monitoring platform at any time.

　　2. The equipment can accurately monitor various parameters and status of the battery pack's group voltage and current, and the voltage and current of single cells. The PMcenter centralized monitoring platform can clearly display the monitored data and status.

　　3. Keep long-term historical event records and support document export, which is convenient for users to trace historical failure events, estimate and judge unknown risks, and take timely solutions to reduce the incidence of accidents.

　　4. When there are abnormal situations such as UPS power failure, communication interruption, low battery voltage, etc., there will be local sound and light buzzing warning reminders, as well as SMS and telephone voice warning methods to send detailed warning reminders to the administrator.

　　 Four, plan configuration

　　 1. PMcenter centralized monitoring system

　　 The PMcenter centralized monitoring system can be used for centralized monitoring of distributed UPS networks. Through the TCP/IP network, the UPS operating status can be monitored across regions in real time, and equipment abnormalities can be found in time to ensure the reliability of the UPS power supply system.

　　 2. UPS monitoring

UPS Network Monitoring Adapter: A UPS-based intelligent network monitoring device that connects to the network through a network cable, continuously collects UPS operating status data, and analyzes UPS operating data in real time. It can be through WEB, SNMP, CLIENT, TELNET, etc. For users to understand the operating status of the equipment! It can also support the expansion of the "Environmental Temperature and Humidity Acquisition Module" to monitor the temperature and humidity of the computer room. And according to the operating conditions of the UPS, when an abnormal situation occurs, an alarm can be sent directly in time via email, SNMP-TRAP, etc. (Each UPS is equipped with one)

　　3. Battery monitoring

Battery network management terminal + 24 battery inspection unit + current sensor: real-time online inspection of the battery voltage and battery current of the series battery pack (charge and discharge current separate detection, with current sensor), and intelligent analysis of battery usage Status, according to different upper and lower limits and average deviation set by the user, automatically judge and output alarms.

　　 4. Alarm module

　　 When the UPS or battery is abnormal, an alarm will be issued immediately to notify the relevant administrator.
