Remote monitoring program of UPS power.
        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.

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.

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.

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 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.

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.
