Power Distribution Monitoring
■Monitoring Targets:
Power distribution cabinet of power distribution room, current quantity of total input wires of main power, status of all secondary contact switches of power distribution cabinet (power distribution cabinet has to add the secondary contact switch on the important switch).    
■Monitoring content:
A,voltage, power, frequency, power factor and gross power of phase of input wire of main power of real time monitoring power distribution cabinet.
B,Working status of secondary contact switch of power distribution cabinet. 
■Characteristics:
It can show and save the value of each monitoring parameters of total input wires of each power distribution cabinet and working status of secondary contact switch of power distribution cabinet. It can set the upper limit value and lower limit value. When the monitored voltage or current is beyond the permissible value the system can be judged as the fault (warning) the main monitoring system will immediately pop up the relative warning windows, meanwhile, the monitoring main machine will send the multimedia voice warnings and text-messages to inform the workers on duty or officer on charge. They can check any monitoring targets of historical records (lists and graphs).
UPS Monitoring System

■Monitoring Targets:
UPS main machine and battery units in the power distribution room.  
■Monitoring content:
A, Analogue
Input phase voltage, output phase voltage, bypass phase voltage, input phase current, output phase current, bypass phase current, battery voltage, battery current, system frequency, system load, battery standby time. 
B, Digital quantity
over-range output voltage, battery working method, bypass working method, high battery voltage, low battery voltage, system warning, system suspension, low battery voltage warning, overvoltage warning of bypass, overvoltage of main power.
■Characteristics:
It can show and save the real-time remote operation parameters that the UPS communication protocols provide and the status of each component.      
It can judge the components of UPS whether they are sending the warning. When the some components of UPS are on the failure or out of limit the main monitoring system will immediately pop up the relative warning windows, meanwhile, the monitoring main machine will send the multimedia voice warnings and text-messages to inform the workers on duty or officer on charge. They can check any monitoring targets of historical records (lists and graphs).
Cooling System Monitoring

■Monitoring Targets:
It can make the real-time monitoring and management for the accurate air-conditioners in the computer rooms. It also can remotely make the centralized monitoring and management for them through the interfaces and communication protocols which the factory offered.      
■Monitoring content:
A, Monitoring parts
Return air temperature, return air humidity, return air temperature upper limit value, return air humidity upper limit value, return air temperature lower limit value, return air humidity lower limit value, temperature setting value, humidity setting value, operating status of air-conditioner, operating time of compressor, percentage of heating, percentage of cooling, operating status of heater, operating status of dehumidifier, operating status of humidifier, temperature/ humidity changing graphs, compressor high pressure alarm, compressor low pressure alarm, air-conditioner water leakage alarm, temperature/humidity over-high alarm, temperature/humidity over-low alarm, humidifier fault alarm, main fan overload alarm, humidifier what-short alarm, filter blocking alarm.        
B,Management parts
Remote start-up and close-down for the air-conditioner, remote setting of temperature/ humidity.   
All monitoring of air-conditioner and some specific conditions of controlling are based on the communication protocol that factory offered.  
■Characteristics:
It can monitor the operation status of air-conditioner the changing of graphs and colors can show the working status of air-conditioner. When it occurs the fault it will send the warnings which include the operation status of heater, compressor high pressure fault, filter blocking and so on. The users can remotely monitor and control the air conditioners starting-up, closing-down and setting value of temperature/humidity through this monitoring system in the monitoring room.
It can show and save the real-time remote operation parameters that the air conditioner communication protocols provide and the status of each component. When the system is sending the warnings the main monitoring system will immediately pop up the relative warning windows, meanwhile, the monitoring main machine will send the multimedia voice warnings and text-messages to inform the workers on duty or officer on charge. They can check any monitoring targets of historical records (lists and graphs).
Water Leakage Warning System

Because the computer rooms have the accurate air-conditioners, heaters and other equipments the water leakage occurs from the time to time, meanwhile the tap water will possibly enter in the computer rooms, this is need us to find it early that can ensure the equipments of computer rooms to operate normally. In case the water leakage occurs the system will automatically make the alarm which uses the visual graphs to show the situation the system adopts the position leakage controller. It can use the cables of the leakage sensor around the air-conditioners when the water leakage occurs the system will send the warning or voice warning to inform the relative personnel to deal with it. It can send the water leakage message and location to the monitoring main machine through the RS485 communication interface to achieve the real-time water leakage testing.  
The water leakage system consists of one sensing cable of leakage and alarm controller. When the leakage occurs the sensing cable connects with the water or other liquids it will immediately send the signal to the alarm controller the red light is on, meanwhile it is warning, it shows the leakage location through the microprocessor (TTDM controller). In the normal situation the green light of controller is on that means it is safe, when the yellow light is on that means the cable is on the failure it need to be fixed up. After the cleaning up the leakage the cable should be dryed and then return back to work. 
The sensing cable of water leakage senses the water round the air conditioner the signal will send back to the controller because it outputs the RS485 signal itself that use two quad pair cables to make the controller in series on one main cable (to leave one cable for standby ). the RS485 main cable signal will be sent to the conversion module to make the RS232 signal and then send back t the intelligent communication card. The system can monitor the processed warning signals which they are the water leakage and fault (system is broken down) warning.
