[0002] With the continuous development of IT technology, computer rooms are generally equipped with uninterruptible power supplies (UPS) to prevent losses caused by power outages in the computer room. Common uninterruptible power supplies (UPS) have very simple functions. Generally, they only provide short-term emergency power supply after an unexpected power outage in the computer room. This simple emergency power supply function can no longer meet the existing IT computer room operation and maintenance safety requirements. For example, when a fire or abnormal high temperature is found in the computer room, the existing uninterruptible power supply UPS still maintains power supply, or even continues emergency power supply, so that the equipment in the computer room is still in a power supply working state, and the equipment in the computer room is in an unsafe operation state, which poses a relatively large safety hazard.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] According to the embodiment of the utility model, Figures 1 to 3 As shown, an uninterruptible power supply device for a computer room includes a smoke sensor 1, a temperature sensor 2, a programmable controller PLC3, a first contactor 5 and a second contactor 7; the signal output end of the smoke sensor 1 and the signal output end of the temperature sensor 2 are connected to the signal input end of the programmable controller PLC3 in a one-to-one correspondence; the signal output end of the programmable controller PLC3 is connected to the coil end of the first contactor 5 and the coil end of the second contactor 7 in a one-to-one correspondence; the external power supply is connected to the power input end of the UPS power supply 6 through the normally closed contact of the first contactor 5, and the power output end of the UPS power supply 6 is connected to the power input end of the power strip 8 through the normally open contact of the second contactor 7; the programmable controller PLC3 is connected to the 4G communication module 4 through the RS485 interface; the power supply end of the smoke sensor 1, the power supply end of the temperature sensor 2, the power supply end of the programmable controller PLC3 and the power supply end of the 4G communication module 4 are all connected to the power output end of the power strip 8.

[0028] In this embodiment, if Figures 1 to 3 As shown, the signal output terminal of the programmable controller PLC3 connected to the coil terminal of the second contactor 7 outputs a normally open signal, so the programmable controller PLC3 controls the normally open contact of the second contactor 7 to be in a normally closed state.

[0029] The device has three modes of use:

[0030] Normal power supply mode: When the power strip 8 is supplying power normally, the external power supply supplies power to the power input terminal of the UPS power supply 6 through the normally closed contact of the first contactor 5. At this time, since the normally open signal output by the signal output terminal of the programmable controller PLC3 supplies power to the coil terminal of the second contactor 7, the normally open contact of the second contactor 7 is in a normally closed state. Therefore, the UPS power supply 6 supplies power to the power strip 8 normally.

[0031] First emergency mode: When the smoke sensor 1 and the temperature sensor 2 collect abnormal signals exceeding the first threshold in the computer room, the programmable controller PLC3 controls the first contactor 5 to cut off the external power supply. At this time, the state of the second contactor 7 remains unchanged, so the UPS power supply 6 supplies power to the power strip 8 normally through the second contactor 7. At this time, the computer room is in a state of external power cutoff, but the UPS power supply 6 is in a normal power supply state. The programmable controller PLC3 sends the status signal in the computer room to the remote network through the 4G communication module 4.

[0032] Second emergency mode: When the smoke sensor 1 and the temperature sensor 2 collect abnormal signals in the computer room that further exceed the second threshold value, the programmable controller PLC3 controls the first contactor 5 to cut off the external power supply, controls the coil end of the second contactor 7 to no longer be adsorbed, and the normally open contact of the second contactor 7 returns to the open state. The power strip 8 no longer supplies power. At this time, all equipment in the computer room is powered off.

[0033] In this embodiment, the power output end of the power strip 8 is connected to the equipment load 10 arranged in the computer room, and the equipment load 10 includes a server, a data storage device, etc. in the computer room.

[0034] According to the embodiment of the utility model, Figure 1 As shown, the 4G communication module 4 is connected to the remote monitoring computer 9 via the mobile Internet.

[0035] According to the embodiment of the utility model, Figure 3 As shown, the smoke sensor 1, the temperature sensor 2, the programmable controller PLC3, the first contactor 5 and the second contactor 7 are all arranged in the cabinet.

[0036] According to the embodiment of the utility model, Figure 3 As shown, the UPS power supply 6 is arranged in the cabinet.

[0037] According to the embodiment of the utility model, Figure 3 As shown, the smoke sensor 1 and the temperature sensor 2 are arranged on the top of the cabinet.

[0038] According to the embodiment of the utility model, Figure 3 As shown, a handle for moving the cabinet is provided on the top of the cabinet.
