Description

Technical Field

[0001] The utility model specifically relates to a comprehensive cabinet and an intelligent cabinet system. Background Art

[0002] Compared with 4G networks, 5G networks have faster Internet access speeds, lower latency, and can achieve multiple connections at the same time. However, due to the high frequency spectrum of 5G networks, more base stations need to be deployed, and the base stations are denser.

[0003] The existing BBU (Building Base band Unit) base station construction originated from the traditional machine room, which adopts the traditional BBU base station construction mode in the 4G era. Multiple subsystems are purchased and built separately, and each subsystem is managed independently, which has a long overall construction period. The compatibility of each subsystem is poor, and the compatibility test is affected by the on-site conditions. It is impossible to achieve the conditions for the highest efficiency, and the space utilization rate is low.

[0004] Currently, there is also a method of centrally deploying and stacking BBUs, which can not only reduce the investment in new equipment rooms, but also achieve rapid deployment. With the continuous investment in stacked equipment rooms and the update and iteration of equipment, some equipment rooms have already had limited space, mixed cold and hot airflows, resulting in reduced cooling efficiency, etc. Figure 1 As shown in the figure, air conditioner A can cool down the entire computer room, but cannot effectively cool down the equipment in cabinet B, resulting in excessive overall energy consumption of the equipment in the computer room, with a PUE value (PUE value refers to the ratio of all energy consumed by the data center to the energy consumed by the IT load) as high as 1.7-2.0. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a comprehensive cabinet and an intelligent cabinet system in view of the above-mentioned deficiencies in the prior art, which can enable the air conditioner to cool the inside of the cabinet alone, thereby improving the cooling efficiency of the air conditioner inside the cabinet and reducing the overall energy consumption of the computer room.

The plug-in frames are stacked above the air conditioner in the cabinet body; the plug-in frames and the air conditioner isolate the space in the cabinet body into mutually independent cold channels and hot channels, the cold channel is located in the front part of the cabinet body, and the hot channel is located in the rear part of the cabinet body. The baseband processing unit is vertically arranged in the plug-in frame; the air conditioner is used to inhale the air in the hot channel and blow it out into the cold channel after cooling it, and the cooled air enters the plug-in frame to cool the baseband processing unit and is then discharged to the hot channel. The natural cold source thermal control component includes an air intake module and an air exhaust module. The air inlet module is arranged on the front side panel of the cabinet, the cold channel is connected with the outside of the cabinet through the air inlet module, and the air inlet module is used to transport the air outside the cabinet to the cold channel when starting; the exhaust module is arranged on the rear side panel of the cabinet, the hot channel is connected with the outside of the cabinet through the exhaust module, and the exhaust module is used to exhaust the air in the hot channel to the outside of the cabinet when starting.

[0007] In some embodiments, the natural cold source thermal control component further includes a first temperature sensor, a second temperature sensor and a controller. The first temperature sensor is disposed outside the cabinet, and is used to detect the ambient temperature outside the cabinet and output a first temperature signal. The second temperature sensor is disposed at the upper part of the hot channel, and is used to detect the temperature in the hot channel and output a second temperature signal. The controller is electrically connected to the first temperature sensor, the second temperature sensor, the air intake module, the exhaust module, and the air conditioner, respectively, and is used to control the start and stop of the air intake module, the exhaust module, and the air conditioner according to the received first temperature signal and the second temperature signal.

[0008] In some embodiments, the natural cold source thermal control component further includes an air intake module indicator light and an exhaust module indicator light.

The controller is also electrically connected to the air intake module indicator light and the exhaust module indicator light, respectively, for controlling the light emission colors of the air intake module indicator light and the exhaust module indicator light according to the start and stop of the air intake module and the exhaust module.

[0009] In some embodiments, the subframe has an air inlet and an air outlet; the air inlet is located at the lower front of the subframe and communicates with the cold channel; the air outlet is located at the upper rear of the subframe and communicates with the hot channel. The air cooled in the cold channel enters the subframe through the air inlet of the subframe, cools the baseband processing unit in the subframe, and is discharged from the air outlet to the hot channel.

[0010] In some embodiments, a plurality of baseband processing units are disposed in one of the plug-in frames, and the plurality of baseband processing units are sequentially disposed in the plug-in frame in a horizontal direction.

[0014] Therefore, the integrated cabinet provided by the embodiment of the utility model can realize the circulation of air in the cabinet by setting up a cabinet body, and using the plug-in frame and the air conditioner to isolate the space in the cabinet into independent cold channels and hot channels. The air conditioner sucks the air in the hot channel and blows it out into the cold channel after cooling it. The cooled air enters the plug-in frame to cool the baseband processing unit and is discharged to the hot channel. Moreover, the air conditioner in the cabinet only cools the equipment in the cabinet, and the low-temperature air blown out by the air conditioner does not flow to the outside of the cabinet to cool the air outside the communication room, which can improve the utilization rate of the cooling capacity of the air conditioner, help reduce the energy consumption of the air conditioner, reduce the overall operating energy consumption of the equipment in the room, and thus reduce the PUE value.

Therefore, the overall operating energy consumption of the equipment in the computer room can be further reduced, and the PUE value can be reduced.

[0015] In the second aspect, the embodiment of the utility model also provides an intelligent cabinet system, which includes the integrated cabinet and the monitoring component in the first aspect.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment 1:

[0025] Combination Figure 2 and Figure 3 The utility model embodiment provides a comprehensive cabinet, which is used in a communication room. Figure 1 As shown, the integrated cabinet includes a cabinet 1, an air conditioner 2, a plug-in frame 3, a baseband processing unit 4 and a natural cold source thermal control component. The air conditioner 2 is arranged in the middle of the cabinet 1 and is located at the bottom of the cabinet 1. The plug-in frame 3 is stacked above the air conditioner 2 in the cabinet 1. The plug-in frame 3 and the air conditioner 2 isolate the space in the cabinet 1 into independent cold channels and hot channels. The cold channel is located in the front part of the cabinet 1, and the hot channel is located in the rear part of the cabinet 1. The baseband processing unit 4 is vertically arranged in the plug-in frame 3; the air conditioner 2 is used to inhale the air in the hot channel and blow it out into the cold channel after cooling it. The cooled air enters the plug-in frame 3 to cool the baseband processing unit 4 and is then discharged to the hot channel.

[0026] Exemplarily, the cabinet 1 is located in a communication room, such as Figure 2 and Figure 3 As shown, the cabinet 1 adopts a fully enclosed structure design, and the size of the cabinet 1 is 800mm*1200mm*2200mm. The front door (front side panel) of the cabinet 1 adopts 5+6A+5 hollow tempered glass and metal edging, and there are sealing strips around the front door. The side panels of the cabinet 1 adopt a segmented structure. The front side panels correspond to the cold channel, and the rear side panels correspond to the hot channel. Each side panel can be disassembled and used separately, which is convenient for daily maintenance and installation. The overall load-bearing capacity of the cabinet 1 can reach 3000kg, and it can pass the earthquake resistance test of level 8 and 9 with a load of 800kg.

[0027] The closed structure of the cabinet 1 can reduce dust pollution caused by external operators or the external environment, and extend the service life of the equipment in the cabinet 1.

[0028] Exemplarily, the air conditioner 2 adopts a rack-mounted precision air conditioner, which is mainly composed of a compressor, a blower, a condenser, an air conditioning controller, a thermal expansion valve, an evaporator, a condensing fan, a drying filter and other components, with a power of 8KW.

[0029] like Figure 4As shown, the cold air outlet of the air conditioner 2 faces the cold channel, and the return air outlet of the air conditioner 2 faces the hot channel. The air conditioner 2 inhales the air of the hot channel through the return air outlet and blows it to the cold channel through the cold air outlet after cooling it inside. The space of the cold channel is limited, so the wind pressure in the cold channel is increased, which can improve the cooling effect of the air in the cold channel; the cooled air enters the frame 3 to cool the baseband processing unit 4 and is then discharged to the hot channel, thereby realizing the circulation of air in the cabinet 1.

[0030] The air conditioner 2 in the cabinet 1 only cools the equipment in the cabinet 1. The low-temperature air blown out by the air conditioner 2 does not flow to the outside of the cabinet 1 to cool the air outside the communication room. Therefore, the air conditioner 2 can better cool the equipment in the cabinet 1, improve the utilization rate of the cooling capacity of the air conditioner 2, and enable the air conditioner 2 to use a smaller cooling capacity to meet the cooling demand of the equipment in the cabinet 1, which is beneficial to reducing the energy consumption of the air conditioner 2, thereby reducing the overall operating energy consumption of the equipment in the room and reducing the PUE value.

[0031] Exemplarily, the installation mode of the frame 3 is rack installation.

[0032] It is understandable that cold air will move upward after being heated. By vertically arranging the baseband processing unit 4 in the plug-in frame 3, the air after the heat dissipation of the baseband processing unit 4 is heated up and moves upward, and the airflow movement direction in the plug-in frame 3 can be optimized. Compared with the baseband processing unit 4 arranged horizontally, the airflow dead angle can be avoided, and the cooling effect of the baseband processing unit 4 can be improved.

[0033] Combination Figure 3 and Figure 4 The natural cold source thermal control component includes an air intake module 5 and an air exhaust module 6. The air intake module 5 is arranged on the front side panel of the cabinet 1, and the cold channel is connected to the outside of the cabinet 1 through the air intake module 5. The air intake module 5 is used to transport the air outside the cabinet 1 to the cold channel when starting. The air exhaust module 6 is arranged on the rear side panel of the cabinet 1, and the hot channel is connected to the outside of the cabinet 1 through the air exhaust module 6. The air exhaust module 6 is used to exhaust the air in the hot channel to the outside of the cabinet 1 when starting.

[0034] The air inlet module 5 and the air exhaust module 6 are both in a closed state when not started.

[0035] Exemplarily, the air inlet module 5 includes a fan and a filter, and the filter can filter the inhaled air to prevent dust from entering the cabinet 1. The exhaust module 6 includes a fan.

[0036] For example, when the external temperature is low, the air intake module 5 is started, and the air intake module 5 can transport the air outside the cabinet 1 to the cold channel to fully utilize the external cold air to cool the baseband processing unit 4. At this time, the air conditioner 2 can be turned off or the cooling power of the air conditioner 2 can be lowered, which is beneficial to reducing the energy consumption of the air conditioner 2. When the temperature in the hot channel is high, the exhaust module 6 can be started to discharge the high-temperature air in the hot channel to the outside of the cabinet 1, so that the heat of the air inhaled by the air conditioner 2 is reduced, which is beneficial to reducing the operating load of the air conditioner 2, thereby reducing the energy consumption of the air conditioner 2. Therefore, the overall operating energy consumption of the equipment in the computer room can be further reduced, and the PUE value can be reduced.

[0037] Therefore, the integrated cabinet provided by the embodiment of the utility model can realize the circulation of air in the cabinet 1 by setting the cabinet 1, and making the plug-in frame 3 and the air conditioner 2 isolate the space in the cabinet 1 into mutually independent cold channels and hot channels. The air conditioner 2 inhales the air in the hot channel and blows it out into the cold channel after cooling it. The cooled air enters the plug-in frame 3 to cool the baseband processing unit 4 and then is discharged to the hot channel. Moreover, the air conditioner 2 in the cabinet 1 only cools the equipment in the cabinet 1, and the low-temperature air blown out by the air conditioner 2 does not flow to the outside of the cabinet 1 to cool the air outside the communication room, which can improve the utilization rate of the cooling capacity of the air conditioner 2, help reduce the energy consumption of the air conditioner 2, and reduce the overall operating energy consumption of the equipment in the room, thereby reducing the PUE value. By vertically setting the baseband processing unit 4 in the plug-in frame 3, the airflow circulation direction in the plug-in frame 3 can be optimized, avoiding the generation of airflow dead corners in the plug-in frame 3, and improving the cooling effect on the baseband processing unit 4. By setting the air intake module 5 and the air exhaust module 6, the air intake module 5 can transport the air outside the cabinet 1 to the cold channel, and the air exhaust module 6 can exhaust the air in the hot channel to the outside of the cabinet 1, so as to make full use of the external cold air to cool the baseband processing unit 4, and exhaust the high-temperature air in the hot channel to the outside of the cabinet 1, which is conducive to reducing the operating load of the air conditioner 2, thereby reducing the energy consumption of the air conditioner 2. Therefore, the overall operating energy consumption of the equipment in the computer room can be further reduced, and the PUE value can be reduced.

[0038] In some examples, a smart door lock or a mechanical door lock is provided on the front door of the cabinet 1 .

[0039] In some embodiments, the integrated cabinet also includes a power distribution module, which is disposed in the cabinet 1 and is electrically connected to the air conditioner 2, the baseband processing unit 4, the air intake module 5 and the exhaust module 6 respectively for power supply.

[0040] Exemplarily, the power distribution module is arranged at the rear side of the cabinet 1 .

[0041] Exemplarily, the power distribution module includes DCDU (DC Distribution Unit), PDU (Power Distribution Unit) and UPS (Uninterruptible Power Supply), etc. Other supporting equipment (such as optical transceiver, etc.) are also installed inside the cabinet 1.

[0042] In some embodiments, the natural cold source thermal control component further includes a first temperature sensor, a second temperature sensor and a controller. The first temperature sensor is arranged outside the cabinet 1, and is used to detect the ambient temperature outside the cabinet 1 and output a first temperature signal. The second temperature sensor is arranged at the upper part of the hot channel, and is used to detect the temperature in the hot channel and output a second temperature signal. The controller is electrically connected to the first temperature sensor, the second temperature sensor, the air intake module 5, the exhaust module 6, and the air conditioner 2, respectively, and is used to control the start and stop of the air intake module 5, the exhaust module 6 and the air conditioner 2 according to the received first temperature signal and the second temperature signal.

[0043] Exemplarily, the controller may be a general PLC (Programmable Logic Controller).

[0044] The control principle of the natural cooling source thermal control component is explained below:

[0045] Self-cooling start temperature: A preset temperature value (default value 23°C) used to determine whether to use an external natural cooling source.

[0046] Thermal control start temperature: A pre-set temperature value (default value 35°C) used to switch between different cooling source states.

[0047] Working mode of natural cooling source thermal control components:

[0048] Normal working mode: When the ambient temperature outside the cabinet 1 is greater than the self-cooling start temperature, the controller closes the air inlet module 5 on the front door, starts the air exhaust module 6 on the rear door, and starts the air conditioner 2.

[0049] At this time, the cooling in the cabinet 1 is entirely dependent on the operation of the air conditioner 2 .

[0050] Energy-saving working mode: When the ambient temperature outside the cabinet 1 is ≤ the self-cooling start temperature, and the temperature in the hot channel is ≤ the thermal control start temperature, the controller starts the air intake module 5 on the front door, starts the exhaust module 6 on the rear door, and turns off the air conditioner 2.

[0051] At this time, the ambient temperature outside the cabinet 1 is low, and the cooling demand of the equipment in the cabinet 1 can be met by relying on the low-temperature air outside the cabinet 1. The cooling inside the cabinet 1 is entirely dependent on the low-temperature air outside the cabinet 1 sucked in by the air intake module 5, which can reduce the energy consumption of the air conditioner 2.

[0052] High-load working mode: When the room temperature is ≤ the self-cooling start temperature and the hot air duct temperature is > the thermal control start temperature, the controller starts the air intake module 5 on the front door, starts the exhaust module 6 on the rear door, and starts the air conditioner 2.

[0053] At this time, the ambient temperature outside cabinet 1 is low, but the equipment load in cabinet 1 is high and the heat generated is large. It is necessary to rely on air conditioner 2 and the external low-temperature air to cool the equipment in cabinet 1 to meet the cooling demand under high load conditions in cabinet 1.

[0054] Fire fighting working mode: When the controller receives an external fire fighting signal, it closes the air inlet module 5 on the front door, closes the exhaust module 6 on the rear door, and turns off the air conditioner 2.

[0055] Through the above settings, the start and stop of the air intake module 5, the exhaust module 6 and the air conditioner 2 can be flexibly controlled according to the external ambient temperature and the temperature in the hot channel, so as to fully utilize the lower temperature air outside the cabinet 1 on the basis of ensuring the normal operation of the equipment in the cabinet 1, thereby reducing the operating energy consumption of the air conditioner 2 and reducing the PUE value.

[0056] In some embodiments, the natural cold source thermal control component further includes an air intake module indicator light and an exhaust module indicator light. The air intake module indicator light is arranged on the cabinet 1. The exhaust module indicator light is arranged on the cabinet 1. The controller is also electrically connected to the air intake module indicator light and the exhaust module indicator light, respectively, and is used to control the light emission colors of the air intake module indicator light and the exhaust module indicator light according to the start and stop of the air intake module 5 and the exhaust module 6.

[0057] Exemplarily, the air inlet module indicator light and the air exhaust module indicator light are both arranged on the top of the cabinet 1 .

[0058] Exemplarily, in normal working mode, the controller controls the air intake module indicator light and the air exhaust module indicator light to light blue.

[0059] In the energy-saving working mode, the controller controls the air inlet module indicator light and the exhaust module indicator light to light green.

[0060] In high-load working mode, the controller controls the air inlet module indicator light and the exhaust module indicator light to light yellow.

[0061] In the fire-fighting working mode, the controller controls the air inlet module indicator light and the exhaust module indicator light to light red.

[0062] Through the above settings, it is convenient for the staff to judge the working mode of the natural cooling source thermal control component according to the indicator light of the air inlet module and the indicator light of the exhaust module.

[0063] In some examples, each component in the natural cooling source thermal control assembly is also electrically connected to the UPS. In extreme environments such as power outages or air conditioning equipment failures, when the baseband processing unit 4 and other devices are powered by the UPS, the natural cooling source thermal control system will also be started at the same time, and the temperature in the cabinet 1 can be adjusted at the same time to improve the fault tolerance performance of the integrated cabinet.

[0064] In some embodiments, Figure 5 As shown, the frame 3 has an air inlet 3A and an air outlet 3B; the air inlet 3A is located at the front lower part of the frame 3 and communicates with the cold channel; the air outlet 3B is located at the rear upper part of the frame 3 and communicates with the hot channel. The air cooled in the cold channel enters the frame 3 through the air inlet 3A of the frame 3, cools the baseband processing unit 4 in the frame 3, and is discharged from the air outlet 3B to the hot channel.

[0065] Exemplarily, the portion of the frame 3 between the air inlet 3A and the air outlet 3B forms an air passage, and the baseband processing unit 4 is located in the air passage. The cooled air entering the frame 3 cools the baseband processing unit 4 when flowing through the air passage.

[0066] Through the above arrangement, the air cooled in the cold channel enters the frame 3 through the air inlet 3A at the lower part of the frame 3, and the temperature of the baseband processing unit 4 increases after cooling. Because the heated air itself has a tendency to move upward, the air outlet 3B arranged at the upper part of the frame 3 can facilitate the heated air to be discharged from the air outlet 3B, thereby accelerating the flow rate of the air in the frame 3 and improving the heat dissipation effect of the baseband processing unit 4.

[0067] In some embodiments, Figure 5 As shown, a plurality of baseband processing units 4 are arranged in one plug-in frame 3 , and the plurality of baseband processing units 4 are arranged in sequence in the plug-in frame 3 in the horizontal direction.

[0068] Exemplarily, five baseband processing units 4 are arranged in one subrack 3. Slots are arranged in the subrack 3, and the baseband processing units 4 are arranged in the slots.

[0069] Exemplarily, the overall height of the plug-in frame 3 is 15U, the height of the lower air inlet 3A is 2U, and a cable management rack with a height of 1U is set next to the air inlet 3A to facilitate optical fiber combing. The installation height of the baseband processing unit 4 in the plug-in frame 3 is 11U, and the height of the rear top air outlet 3B is 2U. There is an air guide device (such as an air guide plate) inside the plug-in frame 3 to prevent the air flow inside the plug-in frame 3 from being turbulent. At the same time, the plug-in frame 3 comes with a grounding copper busbar to meet the grounding requirements of the baseband processing unit 4.

[0070] Through the above arrangement, a plurality of baseband processing units 4 can be arranged in the insertion frame 3 , and the heat dissipation effect of the baseband processing units 4 can be ensured while fully utilizing the internal space of the insertion frame 3 .

[0071] In some embodiments, Figure 5 As shown, an exhaust fan 7 is provided at the air outlet 3B of the insertion frame 3 to accelerate the flow rate of air discharged from the insertion frame 3 to the hot channel.

[0072] Exemplarily, the exhaust fan 7 may be in a normally-on state.

[0073] Through the above configuration, the flow rate of the air in the insertion frame 3 can be accelerated, so that more air can enter the insertion frame 3 to dissipate the heat of the baseband processing unit 4, thereby improving the heat dissipation effect of the baseband processing unit 4.

[0074] In some embodiments, Figure 3 As shown, there are multiple insertion frames 3, and the multiple insertion frames 3 are stacked in sequence above the air conditioner 2.

[0075] Exemplarily, one integrated cabinet may be installed with two plug-in frames 3 , and in the case where five baseband processing units 4 are arranged in one plug-in frame 3 , one integrated cabinet may be installed with a maximum of ten baseband processing units 4 .

[0076] Through the above arrangement, the number of baseband processing units 4 that can be installed in the integrated cabinet can be increased, so that one integrated cabinet can dissipate heat for multiple baseband processing units 4, which is beneficial to reducing equipment costs and improving equipment utilization.

[0077] The inventor has verified the energy-saving effect of the above-mentioned integrated cabinet, and the verification process is to transform an existing communication room site.

[0078] The problems existing in the communication room before the renovation are as follows:

[0079] 1. High PUE value and serious energy waste:

[0080] The communication room has a total construction area of ​​about 23.48m2. The main equipment is concentrated in three 600*600 cabinets. Two vertical air conditioners are used to cool the entire room, resulting in a large amount of cold waste. The heat generated by the equipment is dissipated in a way that is neutralized by the cold energy of the air conditioner, and the heat generated by the equipment cannot be accurately taken away, resulting in dense hot spots in the BBU and related equipment, reducing the life of the equipment.

[0081] The overall airflow organization prioritizes the communication room, which cannot effectively control the temperature of the equipment, resulting in increased energy consumption and excessively high PUE.

[0082] 2. The wiring in the communication room is messy and there are no rational wiring devices, which increases the operation and maintenance costs:

[0083] In the communication room, whether it is BBU equipment or transmission equipment, the overlong pigtails in the early connection directly fall off the cabinet surface. There is no reasonable cable management device in the cabinet, the appearance is messy, which damages the brand image. It also increases the operation and maintenance costs after the equipment fails in the later stage.

[0084] 3. Low air conditioning efficiency and insufficient intelligence:

[0085] During the on-site investigation, it was found that the two household air conditioners were not in working condition. The natural temperature in the communication room was about 4°C, but the BBU equipment in the cabinet had already heated up. The air conditioner could not cool the BBU equipment in time, resulting in increased BBU equipment losses.

[0086] After the communication room was renovated using the above-mentioned integrated cabinet, the high temperature phenomenon of the BBU equipment was reduced and the connecting lines could be arranged in an orderly manner. The communication room is predicted to have an average monthly power consumption of 458.64 kW·h. The average monthly power consumption before the renovation was 603.01 kW·h (excluding the average monthly power consumption of transmission and OLT equipment). After the renovation, the energy consumption decreased by 24%, and the average monthly electricity bill was saved by 111.2 yuan (based on 0.77 yuan / kW·h).

[0087] Regarding the air conditioning system in the communication room, the average monthly electricity consumption of the original two household air conditioners (with a power of 8 horsepower) was 1868.72 kW·h. The average monthly electricity consumption of the modified air conditioner 2 was calculated based on the original project data to be 1013.76 kW·h. Compared with the original two household air conditioners, the energy consumption decreased by 45%, and the average monthly electricity bill savings was 658.3 yuan (based on 0.77 yuan / kW·h).

[0088] In summary, after the comprehensive cabinet of the utility model is used for transformation, the overall energy consumption of the communication room can be greatly reduced, the PUE can be reduced, and the operating cost of the communication room can be reduced.

[0089] Embodiment 2:

[0090] The embodiment of the utility model also provides an intelligent cabinet system, which includes the integrated cabinet and the monitoring component in embodiment 1. The monitoring component includes a monitoring host, at least one cabinet internal environment parameter acquisition sensor, at least one cabinet internal power supply parameter acquisition sensor and a display screen.

[0091] Exemplarily, the monitoring host may be a microcomputer. The cabinet internal environmental parameter acquisition sensor includes one or more of a temperature and humidity sensor, a smoke sensor, a water immersion sensor, and an image acquisition sensor. The cabinet internal power supply parameter acquisition sensor includes a voltage sensor or a current sensor. The display screen may be a localized operation and maintenance screen.

[0092] The monitoring host, the cabinet internal environment parameter acquisition sensor, and the cabinet internal power supply parameter acquisition sensor are all arranged inside the cabinet body 1 of the integrated cabinet, and the display screen is arranged outside the cabinet body 1 of the integrated cabinet. The cabinet internal environment parameter acquisition sensor, the cabinet internal power supply parameter acquisition sensor and the display screen are electrically connected to the monitoring host respectively. The cabinet internal environment parameter acquisition sensor is used to collect the environmental parameters inside the integrated cabinet, and send the collected environmental parameters to the monitoring host. The cabinet internal power supply parameter acquisition sensor is used to collect the power supply parameters inside the integrated cabinet, and send the collected power supply parameters to the monitoring host. The monitoring host is used to convert the received environmental parameters and power supply parameters into display signals, and send the display signals to the display screen for display.

[0093] The monitoring host collects, calculates, intelligently analyzes and judges the environmental parameters and power supply parameters in the cabinet 1 through the cabinet internal environmental parameter collection sensors and the cabinet internal power supply parameter collection sensors in the cabinet 1. It can monitor and manage the environment in the cabinet 1 (including basic environmental quantities such as temperature, humidity, and water immersion) and the working conditions of equipment such as BBU (operating parameters of infrastructure such as air conditioner 2 and natural cold source thermal control components, and power consumption of DC distribution units), and display the above-mentioned various parameters and dynamic power efficiency in real time on the display screen through intelligent algorithms, so that the staff can monitor the operation of the integrated cabinet in a timely and convenient manner.

[0094] In some embodiments, the intelligent cabinet system further includes a personal terminal, which is in communication with a monitoring host. The monitoring host is also used to determine whether the integrated cabinet has a fault according to environmental parameters and power supply parameters, and send a fault notification to the personal terminal after determining that a fault has occurred.

[0095] Exemplarily, the personal terminal may be a smart phone, a personal computer, etc.

[0096] For example, when the temperature in the environmental parameters suddenly rises or the current in the power supply parameters suddenly increases, the monitoring host can use this to determine that the integrated cabinet has failed, and then send a fault notification to the personal terminal through SMS, phone, APP, etc. The staff can obtain the fault status of the integrated cabinet through the personal terminal in a timely manner, so that the staff can repair the corresponding fault.

[0097] Through the above settings, the operation and maintenance management of the communication room becomes simpler, smarter and more efficient.

[0098] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
