The document discusses Four-Faith UPS remote monitoring solutions which use cellular networks and IP modems to remotely monitor uninterruptible power supplies (UPS) from a central location in real-time. The system collects data from UPS equipment via IP modems, transfers the data over cellular networks to a remote monitoring center where the data is analyzed and UPS status can be monitored and controlled from any location. This allows issues to be identified early and maintenance to be planned, lowering costs compared to only periodic on-site inspections.

1. Four-Faith UPS remote monitoring solutions
UPS, Uninterrupted Power Supply ,is the high-quality, high-stable storage
battery, static uninterrupted power supply equipment. UPS is widely used in
the telecommunication areas, it is becoming more and more usual to install the
UPS in the machine room.The importance of UPS monitoring is decided by the
UPS application environment, it is not enough to meet the request only by
operating on-duty workers’ times maintenance inspection touring each day or
professional tech workers times on-site inspection touring per week. If
something error happen then it will not be found and solved in time, and it will
cause huge loss.However, adopting the remote monitoring solution could
conveniently conduct clustering management to the scattering UPS and to
offer early warning etc.
Application
UPS monitoring is to continuously collect the data from the uninterrupted
power in the machine room,to conduct the unit monitoring & management to
the PC in the central machine room via remote transferring, it is convenient for
the machine room responsible person to do the effective management, largely
lower the costings and can achieve the 24h non-human monitoring.

2. 2.1 Topology
This system use the public cellular network to achieve the remote relative
data collecting from UPS to server. After TCP/UDP communication connected
between Four Faith IP Modem and server, it can achieve two ways data
transparent communication, it is equal to the local data collecting by
monitoring software, to check and monitor UPS processing condition real time,
to conduct regular maintenance inspecting.
2.2 System form
The whole UPS remote monitoring system is built up by three parts: fore-end
UPS, communication device,remote monitoring centre.
UPS Fore-end UPS
UPS has been becoming the indispensable importance equipment in the
machine room, as the final backup to ensure the computer system power
supply, the working availability and reliability of UPS is going to be the new
hidden danger in information safety! So it is necessary to do the real time
monitoring to each UPS in the machine room, the monitoring include UPS
input voltage, current, frequency, output voltage, current, load, battery voltage,
UPS status, UPS alarming condition etc. UPS status include regular
working,bypass working, battery power supply etc. UPS alarming include
rectification breakdown, contravariant breakdown, battery breakdown etc. It is
mainly monitoring based on the UPS protocol.

3. communication device
Communication device is using Xiamen Four Faith IP Modem, it is mainly
use the operator network to achieve the communication between the fore-end
equipment and remote monitoring centre.When IP Modem is power on, it will
start reading the working parameter storing inside the FLASH, and having
PPP dialing according to parameter. After successfully dialing, IP Modem will
obtain the inside IP address randomly offered by operator(usually 10.X.X.X),
normally this address is not fix. Then IP Modem will actively start the
communication connection to the data centre, and keep the communication
connection working all the time. If the communication connection
breakdown,GPRS IP Modem will immediately re-connect to data centre. Since
IP Modem is actively connecting to data centre,it will require the data centre to
have the fix public IP address or fix domain.After the successful TCP/UDP
communication connecting, it can achieve the two sides data communication
between port and network.
remote monitoring centre
Remote monitoring centre is for manager to conveniently conduct the
managing functions to UPS like real time status checking, basic information
management, remote handling control, setting up of different parameters,user
management etc. Monitoring software will be showing UPS input & output
voltage, load condition, battery capacity, inside temperature,electric supply

4. frequency and UPS basic information and working status as graphic or data. It
will send the alarming report to remind the on-duty person if UPS is not in the
normal condition(electric supply interruption or UPS breakdown etc). The
system could take curve recording for some UPS important processing
parameters and can save more than 1 year. The curve can offer the
convenient position checking line, it will show the detail parameter value,
Max,Min,average etc, convenient for the manager to fully know the processing
condition of UPS, timely to find out, prevent or solve different problems during
the processing of UPS. Monitoring software could set up authority for each
user in advance,limiting that only allowed handling by network manager with
specific address and password.
2.3 system functions
support UPS real time monitoring management 7/24.
support UPS remote control and maintenance. Lower the UPS
management difficulty, increase the working efficiency
support multi-center, multi-site real time monitoring
easy network-building, no need to place cable on site, using the current
cellular network to achieve the data remote communication
powerful data statistics function,convenient for the manager to timely find
out,prevent or solve the different problems during the processing of UPS
Powerful system augmentability, allowing the follow-up equipment direct
adding but no need to change the current network architecture.
system sum-up
The UPS remote monitoring system, based on cellular network, fully take
advantage of the wireless network’s wild coverage, high bandwidth, mobility
etc. It can help the operation person obtain UPS processing status real time,
timely find out the breakdown and potential hidden danger to operate in
advance and solve the breakdown to ensure UPS system safety stable
processing. The network structure of traditional UPS monitoring system is
complex, inconvenient to cable with disadvantage of high costing and difficult
to manager.However this remote monitoring can be achieved easily, Xiamen
Four Faith IP Modem plays very important role in it, only need to connect Four
Faith IP Modem to UPS and do some brief setting, then it can offer the two
sides wireless long distance data communication function for the system with
the advantage of stable working, low power consumption, easy function.
