Detailed Description

Under the premise of rapid improvement of electronic information and manufacturing technology, the construction scale and equipment density of the data machine room in the information communication industry are greatly increased. However, due to the imperfect energy efficiency management, the lack of the intelligence of the devices, and so on, these data centers or computer rooms are also presenting a series of problems, such as excessive energy consumption, sudden load increase, and operation failure of the main device, and are becoming more and more prominent.

At present, 5G network construction work is steadily promoted in China, and the C-RAN mode is adopted in 5G network construction in many cases. Among them, the C-RAN mode is a green Radio access network architecture (Clean system) based on Centralized Processing (Centralized Processing), cooperative Radio (cooperative Radio) and Real-time Cloud Infrastructure (Real-time Cloud Infrastructure). The C-RAN mode can be understood as a mode in which devices such as an indoor baseband processing unit (BBU) and the like are centrally deployed, so that the number of machine rooms can be reduced, supporting resource sharing is realized, the construction cost and the operation cost are reduced, and meanwhile, high-reliability continuous operation of the whole set of communication system is ensured. Therefore, an intelligent energy-saving standby power product such as a cabinet in a 5G scene is urgently needed.

After the power of the accessed commercial power of the conventional cabinet is cut off, some direct current still remains in the cabinet, alternating current equipment in the cabinet can continue to operate under the supply of the direct current, and because certain heat can be generated during the operation of the equipment in the cabinet, the temperature in the cabinet can be greatly increased, so that certain potential safety hazards can be formed on the equipment in the cabinet.

At present, a battery module is usually disposed in a conventional cabinet, and the battery module may be electrically connected to an ac device to supply power to the ac device, so as to ensure normal operation of the ac device, so as to implement functions of the cabinet in information communication.

However, the conventional cabinet cannot intelligently identify the charging and discharging time of the battery module in the cabinet, so that the operation and maintenance cost is increased, the energy conservation, emission reduction and consumption reduction are not facilitated, and the application under a 5G scene is also not facilitated.

In view of this, the present invention provides a cabinet, in which a battery module, a controller, a timer and a power supply unit are disposed in a cabinet control system of the cabinet, the controller may be electrically connected to the battery module through the power supply unit, and then the controller may control the battery module to effectively charge and store electric energy in a valley power rate time period according to a timing signal of the timer, so as to reasonably discharge and supplement ac devices in the cabinet control system in the peak power rate time period, reasonably avoid peak power rates, and better peak clipping and valley filling. Therefore, the utility model can reduce the operation and maintenance cost of the cabinet and is beneficial to reducing the PUE value of the cabinet, so that the cabinet has the effect of integrating intelligence, energy conservation and standby power supply, and the cabinet is beneficial to meeting the application requirement in a 5G communication scene. Meanwhile, through the arrangement of the emergency air inlet, the emergency air outlet and the emergency heat dissipation device, the sealing performance of the cabinet can be ensured while the emergency heat dissipation of the cabinet is realized, so that the energy efficiency of the cabinet is improved.

The PUE value can be used as a measure of the power utilization efficiency of the data center. The PUE value can be understood as the ratio of the total equipment energy consumption of the whole machine system of the cabinet to the equipment energy consumption. The total equipment energy consumption of the complete equipment system of the cabinet can include, but is not limited to, equipment energy consumption, air conditioner energy consumption, lighting energy consumption, power distribution energy consumption or other energy consumption in the cabinet.

It should be noted that, the PUE value of the conventional cabinet is usually 1.5-2 or even higher, and the PUE value of the cabinet of the present invention can be less than or equal to 1.3. Since the PUE value is closer to 1, it means that the degree of greening of a data center such as a cabinet is higher, and energy is saved. Therefore, compared with the traditional cabinet, the cabinet disclosed by the utility model has the advantages that the greening degree is higher, and the energy-saving performance is better.

The cabinet of the present invention will be further described with reference to the accompanying drawings.
