UPS is short of Uninterruptible Power Supply, which is an uninterruptible power supply that contains energy storage devices.When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC-type voltage stabilizer, and it also charges the battery in the machine; when the mains is interrupted (accidental power failure) Immediately, the UPS will continue to supply 220V AC power to the load by switching and converting the DC power of the battery from the battery, so that the load can maintain normal operation and protect the software and hardware of the load from damage. Mainly used to provide uninterrupted power supply for some equipment that requires high power supply stability. It is widely used in: mining, aerospace, industry, communications, national defense, hospitals, computer business terminals, network servers, network equipment, data storage equipment , Emergency lighting systems, railways, shipping, transportation, power plants, substations, nuclear power plants, fire safety alarm systems, wireless communication systems, program-controlled switches, mobile communications, solar energy storage energy conversion equipment, control equipment and emergency protection systems, personal computers, etc.
UPS has become an indispensable important equipment in the computer room. As the last guarantee to ensure the power supply of the computer system, real-time monitoring of each UPS in the computer room is required. UPS monitoring content includes: UPS input voltage, current, frequency, output voltage, current, Load, battery voltage, UPS status, UPS alarm status, etc. UPS status includes normal operation, bypass operation, battery power supply, etc. UPS alarms include UPS faults: rectifier faults, inverter faults, battery faults and other faults. It is mainly monitored based on the content provided by the UPS protocol.
System topology diagram:
Xiamen CAIMORE 4G Modem/CM850 is used in the UPS monitoring system to realize remote management, which greatly saves costs in various aspects and can realize 24-hour unattended operation.
This system utilizes the public cellular network to realize the remote collection of UPS power related parameters by the server. After the CM850 MODEM establishes a TCP/UDP communication connection with the server, it can carry out two-way transparent data transmission. The effect is equivalent to the monitoring software for local collection, real-time viewing and monitoring of UPS operation, and regular maintenance and inspection.
