Problems solved by technology

However, when there are many single disks in the rack, different single disks have different requirements on the working temperature. For some single disks, the same temperature can work normally, and the fan can maintain the current speed. It may have reached the limit of the operating temperature, and the fan speed must be increased to reduce the ambient temperature of the rack in order to work normally
If the fan speed is determined only according to the highest temperature, and ignores the different requirements of different single disks for different operating temperatures, there will be imbalance in temperature adjustment, and if all the fans on the fan disk adjust the speed together, it will also increase energy consumption. Affect fan life

Embodiment 1

[0040]The embodiment of the present invention provides a temperature control method for rack equipment. There are usually multiple single disks in the rack, including power supply disks, main control disks and service disks, and multiple fan groups. The speed of the fan is adjusted to control the temperature of the single disk, such as figure 1 As shown, the temperature control method provided by the present invention specifically includes the following steps:

[0041] Step 10: Obtain the temperature of each single disk in the rack through temperature detection, and perform weighted calculation on the measured temperature of each single disk based on any single disk to obtain the weighted temperature of each single disk.

[0042] In the rack, each single disk has different requirements for working temperature, but each single disk corresponds to a limit temperature that can keep it working normally, that is, the maximum working temperature. If the temperature exceeds the maxim...

Embodiment 2

[0053] On the basis of Embodiment 1 above, the present invention also provides a specific embodiment of a temperature control method for rack equipment. In this specific embodiment, it is assumed that there are a total of 16 single disks in the rack, including single disk 1, single disk 2, single disk 3, single disk 4, ..., single disk 15 and single disk 16, and fans Group 1, fan group 2, fan group 3, and fan group 4 have a total of 4 fan groups, and the specific positions of each single disk and each fan group are as follows: figure 2 As shown in the figure on the left, each fan group includes at least one fan. If the maximum working temperature of single disk 1 is T 1max =100℃, the maximum working temperature of single plate 2 is T 2max =40℃, the maximum working temperature of single disc 3 is T 3max =50°C; and taking the maximum operating temperature of single disk 1 as the benchmark, then T max =T 1max = 100°C. Assume that the measured temperatures of single disk 1,...

Embodiment 3

[0059] On the basis of the above-mentioned embodiment 1 and embodiment 2, the embodiment of the present invention further provides a temperature control system for rack equipment, which is used to implement the temperature control method in embodiment 1 and embodiment 2. refer to Figure 5 , the system includes a rack backplane, a plurality of single disks and at least one fan disk, and a single disk can be divided into a power supply disk, a main control disk and a service disk according to functions, and a temperature detection unit and a management unit are arranged in the single disk and a control unit, the fan tray is provided with one or more fan groups, and a drive unit, each fan group includes at least one fan, and the temperature of a single disk is controlled by adjusting the speed of the fans in the fan group.

[0060] continue to refer Figure 5 In the accompanying drawings, there are 1 power supply panel, 1 main control panel, 2 fan panels (respectively denoted a...

Abstract

The present invention relates to the field of communication technology, and in particular to a temperature control method and system for rack equipment, wherein the method includes: obtaining the temperature of each single disk in the rack through temperature detection, and using any single disk as a reference to control the temperature of each single disk in the rack. The temperature value of a single disk is weighted and calculated; according to the preset temperature classification method and the weighted temperature of each single disk, set the corresponding temperature level for each single disk to obtain the temperature level array; according to the pre-saved fan speed and temperature level array Corresponding relationship, determine the current required fan speed, and adjust according to the speed. By adjusting the fan speed to control the rack temperature, it has the effects of energy saving and noise reduction. The present invention performs weighted calculation on the temperature of each single disk, sets the temperature classification, and directly determines the required fan speed according to the obtained temperature level array, which not only comprehensively considers The temperature requirement of each single disk also simplifies the analysis and processing process of the temperature of each single disk, which is beneficial to realize the balanced adjustment of temperature.

Description

【Technical field】 [0001] The present invention relates to the field of communication technology, in particular to a temperature control method and system for rack equipment. 【Background technique】 [0002] In a communication system, a rack device generally consists of a chassis, a backplane, and multiple single disks. Single disks can be divided into power disks, main control disks, and service disks according to their functions. In order for the rack equipment to work normally, it is necessary to strictly consider the requirements of temperature, humidity control and electromagnetic protection, so it needs to be designed as a relatively closed structure. Functional devices such as power supply panels, main control panels, and service panels will release a large amount of heat energy when running inside the rack. In order to prevent adverse effects on these functional devices due to overheating, the ambient temperature control in the rack is the primary key factor. In orde...
