Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, an embodiment of the present invention provides a linkage control method for a data center cooling system, including:
s101: acquiring a temperature value of the battery pack and a current environment temperature value, and determining a target temperature control coefficient according to the current environment temperature value and the temperature value of the battery pack;
s102: acquiring the current of the battery pack, and determining a target current control coefficient according to the current of the battery pack;
s103: determining a fan control coefficient according to the target temperature control coefficient and the target current control coefficient;
s104: and controlling the running speed of the fan according to the fan control coefficient.
The fan in the data center is used for assisting the local cooling of the battery pack, and the current of the battery pack can influence the temperature of the battery pack, so that the fan control coefficient is calculated by comprehensively considering the current environment temperature, the temperature of the battery pack and the current of the battery pack, the running speed of the fan is controlled according to the fan control coefficient (the fan is turned off when the running speed of the fan is 0), the fan is controlled more finely, the intelligent degree is higher, the energy consumption of the fan is reduced, the speed change of the fan is continuous, faults cannot occur, the fan cannot be frequently started and stopped, and the service life of the fan is prolonged.
In order to ensure the accuracy of temperature acquisition, the current environment temperature should be the environment temperature in the battery pack area, the current environment temperature acquisition device cannot be far away from the battery pack,
in some embodiments, S101 may include:
s1011: determining a first difference value between a temperature value of the battery pack and a current ambient temperature value;
s1012: and determining the temperature control coefficient corresponding to the temperature threshold interval where the first difference is located as a target temperature control coefficient according to the corresponding relation between the preset temperature threshold interval and the temperature control coefficient.
Because the cooling of data center fan is the auxiliary means of the whole cooling of air conditioner, if current ambient temperature is too high, then the group battery ambient air temperature all is higher, can not be through opening the fan with higher speed the air flow cooling. If the temperature of the battery pack caused by overhigh current environmental temperature is higher, the temperature is still required to be reduced through an air conditioner, and the significance of starting the fan is not great, so that the resource waste is caused. Therefore, in the embodiment of the invention, the target temperature control coefficient is determined according to the first difference value between the temperature value of the battery pack and the current environment temperature value, so that the rotating speed of the fan is controlled, resources are saved, and noise is reduced.
The corresponding relation between the preset temperature threshold interval and the temperature control coefficient can be set according to actual application requirements.
In some embodiments, S102 may include:
s1021: and determining the current control coefficient corresponding to the current threshold interval where the current of the battery pack is positioned as a target current control coefficient according to the corresponding relation between the preset current threshold interval and the current control coefficient.
In some embodiments, the current of the battery pack comprises: current direction and value of current; the preset corresponding relation between the current threshold interval and the current control coefficient comprises the following steps: the corresponding relation between the charging current threshold interval and the current control coefficient and the corresponding relation between the discharging current threshold interval and the current control coefficient; s1021 may include:
s10211: if the current direction is the charging direction, determining a current control coefficient corresponding to the charging current threshold interval in which the current value is located as a target current control coefficient according to the corresponding relation between the charging current threshold interval and the current control coefficient;
s10212: and if the current direction is the discharging direction, determining the current control coefficient corresponding to the discharging current threshold interval in which the current value is positioned as the target current control coefficient according to the corresponding relation between the discharging current threshold interval and the current control coefficient.
The battery is charged according to a preset current value usually during charging, so that the charging duration is long; the current during discharging is related to the load, and the discharging current is very large when the load is large. Because the battery has different charging and discharging characteristics, different corresponding relations are set for different current directions in the embodiment of the invention.
In some embodiments, after obtaining the current of the battery pack, the coordinated control method of the data center cooling system may further include:
s105: acquiring theoretical current of the battery pack;
s106: and if the second difference between the current of the battery pack and the theoretical current of the battery pack is larger than the preset difference, sending an alarm instruction.
And if the deviation between the sampled current of the battery pack and the theoretical current of the battery pack is large, indicating that the battery is abnormal or the current sampling is abnormal, sending an alarm instruction to inform related personnel of overhauling. Meanwhile, the execution of the program can be terminated at the same time when the alarm instruction is issued.
In some embodiments, S103 may include:
s1031: and determining the sum of the target temperature control coefficient and the target current control coefficient as a fan control coefficient.
In some embodiments, S104 may include:
s1041: if the fan control coefficient is not smaller than the preset threshold value, controlling the fan to run at full speed;
s1042: and if the fan control coefficient is smaller than the preset threshold value, controlling the rotating speed of the fan according to the fan control coefficient.
In some embodiments, the preset threshold may be 1.
In some embodiments, the value ranges of the target temperature control coefficient and the target current control coefficient are both 0-1.
In the embodiment of the invention, the target temperature control coefficient and the target current control coefficient are combined, and the influence of temperature and current is comprehensively considered to control the fan.
The value range of the target temperature control coefficient can be 0-1, and when the target temperature control coefficient is 0, the temperature has no influence on the speed regulation of the fan; if the target temperature control coefficient is 1, the fan can be controlled to operate at full speed. Theoretically, since the battery heats, the temperature value of the battery pack is greater than the current ambient temperature value, and the first difference is greater than 0, but the first difference may be smaller than 0 due to influence of other battery packs or calculation errors, and when the first difference is smaller than 0, the target temperature control coefficient may be 0.
The value range of the target current control coefficient can also be 0-1, and when the target current control coefficient is 0, the current has no influence on the speed regulation of the fan; if the target current control coefficient is 1, it indicates that the current of the battery pack is large, and the full-speed operation of the fan needs to be controlled. The current is limited when the battery is charged, the time is long, the influence on the fan is small, and the value range of the target current control coefficient can be 0-0.5; the current is large when the battery discharges, and the value range of the target current control coefficient can be 0-1.
And when the sum of the target temperature control coefficient and the target current control coefficient is not less than 1, controlling the full-speed operation of the fan.
In some embodiments, the battery pack comprises at least two cells; s101 may further include:
s1015: respectively acquiring temperature values of all batteries in the battery pack;
s1016: and selecting the first N temperature values from the temperature values of the batteries in the battery pack according to the sequence of the temperature values from high to low, and determining the average value of the first N temperature values as the temperature value of the battery pack.
Because the battery pack comprises a plurality of batteries, in order to improve the accuracy of the temperature value of the battery pack, the temperature of each battery can be respectively collected, and higher N temperature values are selected to be used as the temperature value of the battery pack on average. Or if the battery packs are arranged in layers, the temperature value of each layer can be respectively collected, and a plurality of higher temperature values are selected to be used as the temperature value of the battery packs on average.
Because the batteries in the battery cabinet of the data center are arranged in a layered mode, one fan can be arranged on each layer, and each fan can be controlled independently or simultaneously by applying the method in the embodiment. For example, if the battery pack temperature high points acquired by the battery pack temperature acquisition device are located on the same layer, the fan on the layer is controlled to be started, local hot points are eliminated, and energy consumption is reduced.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
