Description

Technical Field

[0001] The utility model relates to the field of security systems in data centers, and in particular to a skylight control system for a computer room in a data center. Background Art

[0002] Currently, the skylight systems in domestic data centers and intelligent computing centers still use a very traditional electromagnetic lock solution. The general principle is: a circuit breaker with tripping capability on the high-voltage side (AC220V) is converted to DC24V by an AC / DC switching power supply, and then connected to the electromagnetic locks of all skylights in a room. This skylight system has the following disadvantages:

[0003] 1) When a fire alarm occurs, the main power switch is cut off through the trip signal, all skylights are opened, and the background cannot monitor the status of each skylight;

[0004] 2) When the skylight needs to be manually opened for maintenance, the only option is to turn off the main power switch, which is very inflexible. If the skylight is not discovered in time, cold air from the cold aisle can easily leak out of the cabinet. If it is not discovered for a long time, it may cause the risk of downtime of servers and other network equipment.

[0005] 3) Based on a 6-story data center room (500 cabinets per floor, 130 skylight electromagnetic locks per floor, and a power consumption of 6W per electromagnetic lock), 130 * 6W = 780W * 6 floors = 4680W. This 4680W of heat requires an air conditioner with a 3P cooling capacity to offset the heat generated by the electromagnetic locks, resulting in a power consumption of 2400W.

[0006] By calculation: about 7 kWh per hour * 24 hours * 365 days = 56,414 kWh per year * 0.9 yuan = 61,320 yuan per year (5,110 yuan per month);

[0007] In summary, the heating problem of electromagnetic locks in computer rooms leads to invisible waste of electricity every year. Currently, the PUE requirements for computer rooms are getting higher and higher. It is particularly important to solve the heating and power consumption problems of skylight electromagnetic locks. At the same time, there are also great risks and hidden dangers to the stability and reliability of electromagnetic locks. Utility Model Content

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, Figure 1 This is a schematic diagram of the architecture principle of a skylight control system for a data center computer room in the present invention; Figure 2 This is a schematic diagram of the structure of an electric lock in a skylight control system of a data center computer room in the present invention; Figure 3 This is a schematic diagram of a skylight control system for a data center computer room in the present invention when the skylight is in a normally closed state; Figure 4 This is a schematic diagram of a skylight control system for a data center computer room in the present invention when the skylight is in an open state; a skylight control system for a data center computer room, comprising a main control unit 10, a sub-control unit 20 and a plurality of electric locks 30, the electric lock 30 comprising an electric switch controller 31 and a hook connector 32, the electric switch controller 31 being fixed on a fixed plate of a computer room skylight 40, the connecting end of the hook connector 32 being connected to a skylight flap 42 of the computer room skylight 40 by a threaded fixing method, the hook end of the hook connector 32 being hooked and connected to the switch mechanism of the electric switch controller 31, the electric switch controller 31 being electrically connected to the sub-control unit 20, the sub-control unit 20 being communicatively connected to the main control unit 10, the main control unit 10 being electrically connected to a fire warning system 50 of the computer room, the main control unit 10 and the sub-control unit 20 being electrically connected to an external power supply.

[0028] The utility model uses an electric lock to control the closing and opening of the skylight flap in the machine room skylight. The skylight flap and the bottom plate end of the hook connector of the electric lock are fixed by screws. The other end of the hook connector is a circle end. When the skylight flap is in the closed state, the circle end is inserted into the spring buckle of the switch mechanism of the electric switch controller. The circle end is pulled by the electric switch controller. At this time, the skylight flap will not flip over and is in the closed state. The electric lock is fastened to the frame of the machine room skylight by screws. The machine room skylight is installed above the cold channel. The extension and retraction of the spring buckle of the electric switch controller is controlled by a signal sent by the sub-control unit. When the signal is sent, the spring buckle retracts. This time, the circle end is not subject to the pulling force of the electric switch controller. The skylight flap will flip over under the action of its own gravity. At this time, the skylight flap is in the open state. The sub-control unit is mainly used to receive the communication signal of the main control unit, and then convert it into the control signal of the electric switch controller, so as to complete the control of the sunroof switch. The main control unit decides whether to send a communication signal based on the signal of the monitored fire protection system. If the fire protection system detects that the temperature sensor and the smoke sensor have signals at the same time and determines that fire protection is currently required, a fire protection signal will be generated and transmitted to the main control signal.

[0029] As for how the sub-control unit ensures the power supply and the control of the sunroof flip signal, preferably, the sub-control unit 20 includes a plurality of sub-control modules 21 that are communicatively connected to each other, and the sub-control module 21 includes a sub-control box 22 and a dual-way power supply ATS switch 23, a DC24V power supply 24, and a sunroof controller 25 located in the sub-control box. The input end of the dual-way power supply is electrically connected to the mains end via the ATS switch 23, and the output end of the dual-way power supply is electrically connected to the input end of the DC24V power supply 24 via the ATS switch 23. The output end of the DC24V power supply 24 is connected to the power input end of the sunroof controller 25, the signal output end of the sunroof controller 25 is electrically connected to the signal receiving end of the electric switch controller 31, and the communication input end of the sunroof controller 25 is communicatively connected to the main control unit 10.

[0030] The sub-control unit can be divided into multiple sub-control modules. The sub-control modules have independent power supply circuits and sub-control controllers, which are integrated in a sub-control box. The sub-control modules can usually control multiple skylights, such as 7. If a machine room has 14 skylights, 2 sub-control modules need to be installed. Each sub-control module has dual-channel power through ATS switcher, DC24V power supply, and skylight controller. The dual-channel power is connected to two mains power through the ATS switcher to ensure that if one power supply fails, the other power supply can continue to be used as a redundant power supply. The DC24V power supply converts the mains power into a low-voltage 24V power supply to power the skylight controller. The skylight control receives the communication signal from the main control unit and outputs the control signal to the electric lock. The electric lock makes a telescopic movement corresponding to the spring buckle, thereby realizing the flipping and maintenance of the skylight.

[0031] As for how the main control unit ensures power supply and whether fire control is needed, preferably, the main control unit 10 includes a main control box 11 and a dual-way power supply ATS switch 23, a DC24V power supply 24, and a PLC controller 12 located in the main control box. The dual-way power supply is electrically connected to the mains power end via the input end of the ATS switch 23, and the dual-way power supply is electrically connected to the input end of the DC24V power supply 24 via the output end of the ATS switch 23. The output end of the DC24V power supply 24 is connected to the power input end of the PLC controller 12, the signal receiving end of the PLC controller 12 is electrically connected to the fire warning system 50 of the computer room, and the communication output end of the PLC controller 12 is communicatively connected to the communication input end of the skylight controller 25.

[0032] The main control unit also has a dual-channel ATS switch and a DC24V power supply. Like the sub-control unit, these are used to power the controller. The controller of the main control unit is a PLC controller. These functional device modules are integrated and installed in the main control box. Whether it sends a fire signal to the sub-control unit is mainly determined by whether the PLC controller receives the fire signal transmitted by the fire warning system of the computer room. When the fire warning system sends a fire signal, the PLC controller analyzes the fire signal sent by the fire system and determines which computer room and area has a fire warning, that is, it sends a corresponding communication signal to each sub-control module of the sub-control unit. The corresponding sub-control module recognizes and receives the communication signal, sends a corresponding skylight opening signal, and the electric lock retracts the spring buckle, and the skylight flips over.

[0033] In order to facilitate maintenance and background observation of recorded data, preferably, the main control unit 10 also includes an HMI touch screen 13 and a switch 14, the power input end of the HMI touch screen 13 is electrically connected to the output end of the DC24V power supply 24, the communication output end of the HMI touch screen 13 is communicatively connected to the communication input end of the switch 14, the first communication input end of the switch 14 is communicatively connected to the communication input end of the PLC controller 12, and the second communication input end of the switch 14 is communicatively connected to the background system.

[0034] By configuring the HMI touch screen, a manual signal can be input from the outside to flip the corresponding skylight, allowing maintenance or emergency opening of the skylight. A switch is configured to transmit external operation records and PLC controller control data to the backend for analysis by technical personnel.
