Description
Technical Field
[0001] The utility model relates to the technical field of distribution boxes, and particularly relates to a power distribution acquisition box for a data center. Background Art
[0002] For existing power distribution acquisition boxes in data centers, due to the need to supply power to equipment in the computer room, it is often necessary to mount high-power relays (for example, a high-power relay of model JQX-38F, see Figure 2 ), which results in the size of existing power distribution acquisition box products in data centers (see Figure 3 , the 4 protruding parts in the figure are the installation positions of high-power relays) often reaching 19 inches and 2U in height, which means it needs to occupy one U position of a cabinet. Some customers, for the sake of interests, choose to install the distribution box on the top of the cabinet, which requires wiring transformation, making it not only unsightly but also with messy wiring.
[0003] At the same time, the functions of existing power distribution acquisition boxes are relatively simple. They can only access skylight electromagnetic locks, skylight light strips, and three-color atmosphere lights, and cannot meet some control functions. In addition, they cannot access environmental control components such as water immersion, smoke sensors, temperature and humidity, and cannot provide multiple power supply ports, which makes them increasingly unable to meet the increasingly complex usage requirements. Content of the Utility Model
[0004] In order to meet the more functional usage requirements of power distribution acquisition boxes in data centers, the utility model proposes a power distribution acquisition box for a data center, which includes an acquisition box body and a functional unit fixed inside the acquisition box body. The functional unit includes a PCB control main board, an incoming line switch, a 24V switch power supply, and a 12V / 24V hybrid switch power supply.
[0005] A relay and a functional port set are integrated on the PCB control main board. The functional port set includes a 220V power supply port, a front / rear electric door control port, a dynamic loop skylight status monitoring port, a mobile door partition power supply port, and an alarm linkage port.
[0006] The incoming line switch is used to access external 220V power supply, output the external 220V power supply to the PCB main board, and after being processed by the 24V switch power supply and the 12V / 24V hybrid switch power supply, output corresponding power supply voltages to the PCB control main board.
[0007] Further, the 220V power supply port is used to provide a 220V driving voltage for the front / rear electric doors and the lighting lamps.
[0008] Further, the functional port set further includes a front door double-control switch port and a rear door double-control switch port, which are used to electrically connect double-control switches for controlling the opening and closing of the lighting lamps.
[0009] Further, the front / rear electric door control port is electrically connected to the corresponding electric sliding door controller through the exit button. When the electric door is in the normally closed state, the exit button is disconnected, and the front / rear electric door control port outputs a normally closed electrical signal to the corresponding electric sliding door controller. When the exit button is closed, the normally closed electrical signal is grounded, and the electric door corresponding to the exit button opens.
[0010] Further, the alarm linkage ports include a passive dry contact dynamic loop linkage port, an active fire alarm linkage port, an emergency stop button port, a smoke detector port, an audible and visual alarm port, a water immersion sensor port, and a temperature and humidity sensor port.
[0011] Further, the function port set further includes a skylight reset signal port and a skylight reset push rod port. The skylight reset signal port controls the skylight reset through a normally open self-resetting button. After the normally open self-resetting button is closed, the push rod electrically connected to the skylight reset push rod port controls the skylight to open.
[0012] Further, the dynamic loop skylight status monitoring port is used to collect and feedback the opening and closing status information of the skylight.
[0013] Further, the function port set further includes a first channel light port to an eighth channel light port and a channel light power supply port. The first channel light port to the eighth channel light port are respectively used to electrically connect the channel lights and various color ambient lights, and are powered by the channel light power supply port.
[0014] Further, the function port set further includes a human body sensing port, which is electrically connected to a human body sensing device, and the human body sensing device and the channel lights are linked and controlled.
[0015] Further, the function port set further includes a front / rear door access control machine port and a front / rear door electric lock port, which are respectively electrically connected to the front / rear door access control machines and the front / rear door electric control locks, and the access control machines and the corresponding electric control locks are linked and controlled.
[0016] Compared with the prior art, the present utility model has at least the following beneficial effects:
[0017] (1) A power distribution acquisition box for a data center proposed by the present utility model, by adopting an integrated PCB control main board, integrates more function ports for device access, so that the environmental control components that originally needed external dynamic loop access can be connected to the PCB control main board;
[0018] (2) Provides multiple power supply specifications, can meet the power supply stability in the case of a long channel and multiple loads in the computer room, and can also provide high-voltage drive current for the electric door and the skylight, so as to realize the linkage control of the sliding door and the skylight;
[0019] (3) Abandon the original large-volume relay and adopt a relay that is modularly integrated on the PCB control main board, thereby greatly reducing the volume of the acquisition box, enabling it to be placed inside the channel door box without occupying the cabinet U slot, and also facilitating wiring.

[0023] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0024] Aiming at the deficiencies of the existing products, in order to improve the product power of the products, increase the functional diversity, and solve the problem of space occupation, as Figure 1 shown, the present invention proposes a power distribution acquisition box for a data center, which includes an acquisition box body and a functional unit (fixed on the module installation box) fixed inside the acquisition box body. The functional unit includes a PCB control main board, an incoming line switch, a 24V switch power supply, and a 12V / 24V hybrid switch power supply.
[0025] A relay and a functional port set are integrated on the PCB control main board. The functional port set includes a 220V power supply port, a front / rear electric door control port, a dynamic loop skylight status monitoring port, a mobile door partition power supply port, and an alarm linkage port;
[0026] The incoming line switch is used to access the external 220V power supply, output the external 220V power supply to the PCB main board, and after being processed by the 24V switch power supply and the 12V / 24V hybrid switch power supply, output the corresponding power supply voltage to the PCB control main board.
[0027] In the power distribution acquisition box proposed by the present invention, since the on-board integrated relay of the SLA-xxVDC-SL-A series is adopted, the internal longitudinal and transverse spaces of the power distribution acquisition box are greatly saved. Therefore, in the case of a large reduction in the longitudinal space, the power distribution acquisition box proposed by the present invention can be inserted into the channel door box, and the functional component layout can be planned according to the actual space layout inside the channel door box, so as to meet the requirements of different manufacturers.
[0028] Due to space optimization, we have also configured a 24V switching power supply and a 12 / 24V hybrid switching power supply on the module installation box. By stepping down the 220V power supply connected to the incoming line switch, the corresponding supply voltage is output. The PCB control main board is connected to the supply voltages output by these two switching power supplies, and some function ports are used as power supply ports to supply power to different function carriers. This is more flexible in actual function layout and is not restricted by unified power supply. Connecting the 220V power supply voltage to the PCB control board makes it possible for the PCB control board to supply power to the front / rear electric doors and the lighting in the machine room, and thus enables the linkage control of the sliding doors and the skylight. At the same time, the front / rear door access control machine ports and the front / rear door electric lock ports can also be added to the function port set, and the PCB main board supplies power to the front / rear door electric locks and receives the front / rear door access control machine signals to control the opening and closing state switching of the front / rear door electric locks.
[0029] Moreover, due to the improvement in size and the enhancement of power supply performance, the power distribution and acquisition box proposed by the present utility model integrates more function ports. In the case proposed in this embodiment, the function port set further includes a front door double-control switch port and a rear door double-control switch port. In this way, through the setting of the double-control door control switch, compared with existing products, in addition to the aisle induction lights in the machine room, the constant lighting control of the aisle lighting (which can be induction lights or a separately set light group) can also be carried out through the double-control door control switch, meeting different usage requirements of users.
[0030] At the same time, compared with the situation where existing products can only install warning devices through dynamic loop linkage, in terms of active warning, in the power distribution and acquisition box proposed by the present utility model, the alarm linkage ports of the PCB control main board include a passive dry contact dynamic loop linkage port, an active fire alarm linkage port, an emergency stop button port, a smoke detector port, a sound and light alarm port, a water immersion sensor port, and a temperature and humidity sensor port. The settings of the passive dry contact dynamic loop linkage port and the active fire alarm linkage port enable the fire interface to not only have a 24V active input (provided by the active fire alarm linkage port), but also access the control signal through the passive dry contact port, thus avoiding signal crosstalk and greatly improving the stability of fire control.
[0031] The settings of the emergency stop button port, the smoke detector port, the sound and light alarm port, the water immersion sensor port, and the temperature and humidity sensor port further enable the emergency stop button, smoke detection, sound and light alarm, water immersion detection, and temperature and humidity detection to be directly connected to the PCB control main board, so that there is no need to arrange additional wiring for external dynamic loop linkage, greatly improving the product safety guarantee performance and general adaptability.
[0032] Furthermore, in order to expand the functions of the skylight in the data center computer room passage, the function port set also includes a skylight reset signal port and a skylight reset push rod port. Among them, the skylight reset signal port controls the skylight reset through a normally open self-resetting button. After the normally open self-resetting button is closed, the skylight can be controlled to open through the push rod electrically connected to the skylight reset push rod port. At the same time, a dynamic loop skylight monitoring port is added to collect and feedback the opening and closing state information of the skylight.
[0033] At the same time, compared with the existing power distribution acquisition box, which is limited by the number of ports and can only access three-color ambient lights, due to the increase in port capacity of the present utility model, more ambient light ports can be accessed. Specifically, it includes a first channel light port to an eighth channel light port and a channel light power supply port. Among them, the first channel light port to the eighth channel light port are respectively used to electrically connect the channel lights and various color ambient lights, and the channel light power supply port supplies 24V power to the channel lights and each ambient light.
[0034] In summary, a power distribution acquisition box for a data center proposed by the present utility model adopts an integrated PCB control main board, integrates more function ports for device access, and thus can connect the environmental control components that originally needed external dynamic loop access to the PCB control main board.
[0035] It provides a variety of power supply specifications, can meet the power supply stability in the case of long channels and multiple loads in the computer room, and can also provide high-voltage drive current for the electric door and skylight, so as to realize the linkage control of the sliding door and the skylight.
[0036] Abandoning the original large-volume relay and adopting a relay modularly integrated on the PCB control main board, the volume of the acquisition box is greatly reduced, it can be placed in the channel door box, does not need to occupy the cabinet U position, and is also convenient for wiring.

[0040] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.
