EMS - Environment Monitoring System is a kind of intelligent monitoring system that combines the software technique of embedded system whole solution, SNMP based long-distance monitoring technique, network node technique of sensors, power distribution technique and modularized structure technique and other advanced techniques to timely monitor the micro environment in one or several cabinets.

Composition of EMS: master, slave, HUB and Metered PDU.
Cabinet unit: one cabinet as a unit.
Basic configuration in a cabinet: at most 4 Metered PDU (or CPDU), 2 rack mountable UPS, 2 T/H sensor, 2 door sensor, 1 smog sensor and 1 water-logging sensor.
Microenvironment of cabinet: input voltage, load current and power consumption of Metered PDU (or CPDU) output current, load current, buttery power of rack mountable UPS temperature, humidity, door, smog and water-logging state in cabinet.

EMS Functions
A. Through Internet, EMS can timely monitor the input voltage, load current and power consumption of all the Metered PDU (or CPDU) in one or several cabinets; output voltage, load current, battery power of rack mountable UPS;  temperature/humidity, smog, door and water-logging states around the cabinets.
B. When overload appears, limited range exceeded or some other abnormal situation appears, EMS will send alarming signal.
C. Operation and alarming information of EMS can be saved and inquired by log record.
D. Can classify and set the use's right. User can manager one or several cabinets according to the rights awarded.
E. EMS can be widely applied to communication, telecom, electrical, financial, network system, information solution sectors to monitor the microenvironment in the cabinets through network from long distances.
