UPS system with network monitoring and attached battery pack information sensing functions

A UPS (Uninterruptible Power Supply) system with network monitoring and attached battery pack information sensing functions, comprising a local area network, a UPS apparatus, and at least one attached battery pack connected to said UPS apparatus through said local area network, wherein said UPS apparatus comprises a UPS body and a UPS monitoring module having a web server built in said UPS monitoring module, and each attached battery pack comprises a battery pack body and a battery pack monitoring module, wherein said battery pack monitoring module comprises a control unit, a sensor module electrically coupled to said control unit to sense status information of said respective battery pack body, a memory electrically coupled to said control unit to store predetermined data, and a network interface communicating with said UPS monitoring module through said local area network to transmit said status information of said respective battery pack body to said UPS monitoring module, wherein a web browser of an external equipment links to said web server of said UPS monitoring module and obtains said status information of each attached battery pack through said local area network;

• wherein said web server of said UPS monitoring module of said UPS apparatus provides a newly added page to input an IP address or MAC address of a new attached battery pack from said web browser of said external equipment, to add said new attached battery pack for management, and to transmit a request network packet to said battery pack monitoring module of said new attached battery pack for handshaking from said UPS monitoring module of said UPS apparatus, and after said battery pack monitoring module accepts to be added into management and sends back a reply packet, said new attached battery pack monitoring module timely transmits a network packet of status information to said UPS monitoring module to display or update said status information of said new attached battery pack on the web browser through said web server of said UPS monitoring module.
