The data center machine room is used as a core area of the whole service system, the internal devices are numerous, the coordination is high, and meanwhile, good machine room environments (power supply and distribution, UPS, air conditioner, fire protection, security and the like) are required to be used as basic conditions, so that the operation efficiency of the data center can be effectively exerted. In fact, once environmental equipment of a data center fails, the operation of an IT system is immediately affected, and the reliability of data transmission, storage and system operation is threatened, and if an accident is serious and cannot be handled in time, hardware equipment may be damaged, resulting in serious consequences. Therefore, a data center monitoring system is needed to be constructed to closely monitor the operation environment of the equipment in the machine room and the operation condition of the electromechanical equipment.
At present, a monitoring or management system mainly realizes data acquisition and summarization of data center infrastructure and lacks of linkage control of equipment. In a data center, an Uninterruptible Power Supply (UPS) or a high voltage direct current (hvdc) is generally used to provide power supply. These power supplies require a large number of battery packs and special battery compartments. At present, most of the mainstream applications of the lead-acid storage battery are valve-controlled lead-acid storage batteries, the requirement of the lead-acid storage battery on the environmental temperature is high, and the optimal working temperature is 20-25 ℃. The data show that when the ambient temperature is 25 ℃, the service life of the valve-regulated storage battery is shortened by half and the cycle life of the battery is shortened when the temperature is increased by 6-10 ℃. Therefore, in order to guarantee the practical service life and capacity of the storage battery, a machine room air conditioner is needed to adjust the ambient temperature between the batteries. The air conditioner in the existing data center is normally opened, and the storage battery of the data center is in a floating charge state for most of time, so that no heat is generated basically; and the change of the cold and hot load between the batteries is not large due to the external influence, so that the normally open air conditioner can cause a large amount of energy waste.

The battery parameter acquisition module acquires the operating parameters of the storage battery. And the monitoring module judges the working state of the storage battery according to the storage battery operating parameters. When the storage battery is in a floating charging state, the ambient temperature acquisition module acquires the ambient temperature between the batteries.

Detailed Description
As shown in fig. 1, the method for controlling linkage of the air conditioner in the battery room of the data center provided by the embodiment includes acquiring an operation parameter of a storage battery (step S10); judging the working state of the storage battery according to the storage battery operation parameters (step S20); acquiring the ambient temperature between the batteries when the storage battery is in a float-charged state (step S30); judging whether the ambient temperature between the batteries is greater than or equal to a set threshold (step S40); when the ambient temperature between the batteries is greater than or equal to a set threshold value, starting a refrigeration air conditioner (step S50); the cooling air conditioner enters a standby state when the ambient temperature between the batteries is less than a set threshold value (step S60). The method for controlling the air-conditioning linkage of the battery room of the data center is described in detail below with reference to fig. 1.
The method for controlling the linkage of the air conditioners in the battery room of the data center provided by the embodiment starts with step S10, and obtains the operation parameters of the storage battery. Under the normal operation state of the data center, equipment such as a UPS (uninterrupted power supply) host machine, an input/output cabinet and the like in the data center adopt an external power supply to supply power, a storage battery is in a standby state, the external power supply keeps the storage battery in a fully charged state by floating and charging the storage battery with small current, and the heat emitted by the storage battery is very slight; the ambient temperature in the battery room is little interfered by the outside, the refrigerating capacity required by the heat dissipation of the battery room is very small, and the refrigerating air conditioner does not need to be opened normally. Therefore, the control method provided by this embodiment first needs to acquire the operating parameters of the battery to determine the state of the battery.
In this embodiment, the battery operating parameters are obtained in two ways, the first way is to directly obtain the operating parameters of the battery by using the battery obtaining module, and the obtained operating parameters include the voltage, the current and the temperature of the battery. In the discharging process of the storage battery, the voltage and the current of the storage battery are both large, and the heat productivity of the storage battery is also large, so that the working state of the storage battery can be obtained by monitoring the voltage, the current, the temperature and other parameters of the storage battery. However, the present invention is not limited to the parameters specifically obtained. In other embodiments, other parameters may be used to characterize the operating state of the battery. The second way is to obtain the operating parameters of the battery by an Uninterruptible Power Supply (UPS), including the battery bus voltage, the battery bus current, the built-in battery temperature, the remaining backup time of the battery, and the percentage relative to the new battery capacity. The monitoring of the two storage batteries ensures the monitoring accuracy of the working state of the storage batteries. However, the present invention is not limited thereto. In other embodiments, the operating condition parameters of the battery may be obtained by either of two methods.
After the operation parameters of the storage battery are obtained, step S20 is executed to determine the operation state of the storage battery through the operation parameters of the storage battery. If in the floating charge state, the external power supply charges the storage battery with a small current so as to maintain the storage battery in a full-charge state, the current on the storage battery and the current on a battery bus are both very small, and the temperature of the built-in battery is also very low; when the storage battery is in a discharging state, the current on the storage battery and the current on the battery bus are both large, and the temperature of the built-in battery is also high. Therefore, after the operation parameters of the storage battery are obtained, the monitoring module obtains the working state of the storage battery by comparing the current operation parameters with the discharge state parameters and the floating charge state parameters set in the module.
When the storage battery is in the float state, step S30 is executed to acquire the ambient temperature between the batteries. In this embodiment, the ambient temperature between the batteries is obtained by a multi-point monitoring method, and particularly, the place where heat is accumulated between the batteries is monitored, and the highest temperature value is selected from the obtained ambient temperatures. However, the present invention does not limit the processing method of the plurality of acquired ambient temperature values. In other embodiments, a weighted average or the like may be used to avoid false monitoring due to temperature sensor failure.
Step S40 is then executed to determine whether the ambient temperature between the batteries is greater than or equal to the set threshold. If the determination result is yes, step S50 is executed to turn on the cooling air conditioner. If the determination result is negative, step S60 is executed, and the cooling air conditioner enters a standby state. Since the heat dissipation has a certain hysteresis, in the present embodiment, when the ambient temperature between the batteries is less than the set threshold, the air conditioner continues to operate for a certain time and then enters the standby state, i.e., step S70.
Of course, if the determination result in step S20 shows that the battery is in the discharged state, step S50 is performed to directly turn on the cooling air conditioner until the discharge is completed, and then step S70 is performed and step S60 is performed.
Corresponding to the control method, the embodiment further provides a linkage control system of the air conditioner in the battery room of the data center, and the linkage control system comprises a battery parameter obtaining module 1, a monitoring module 2 and an ambient temperature obtaining module 3. The battery parameter acquisition module 1 acquires battery operating parameters. The monitoring module 2 judges the working state of the storage battery according to the storage battery operating parameters. When the storage battery is in a floating charge state, the ambient temperature acquisition module 3 acquires the ambient temperature between the batteries. The monitoring module 2 judges whether the ambient temperature between the batteries is greater than or equal to a set threshold value; when the ambient temperature between the batteries is greater than or equal to a set threshold value, starting the refrigeration air conditioner; and when the ambient temperature between the batteries is less than a set threshold value, the refrigeration air conditioner enters a standby state.
Specifically, when the monitoring module 2 determines that the ambient temperature between the batteries is greater than or equal to the set threshold value, the monitoring module 2 outputs an instruction for starting the refrigeration air conditioner to the linkage control module 4, and the linkage control module 4 outputs a signal to the refrigeration module of the refrigeration air conditioner to start the refrigeration air conditioner. And when the monitoring module 2 judges that the ambient temperature between the batteries is less than the set threshold value, the monitoring module 2 outputs an instruction that the refrigeration air conditioner enters a standby state to the linkage control module 4. However, the present invention is not limited thereto. In other embodiments, the monitoring module 2 may be directly connected to the refrigeration air conditioner to directly control the working state of the refrigeration air conditioner.
In this embodiment, the battery parameter obtaining module 1 includes a storage battery obtaining module 11 and an uninterruptible power supply obtaining module 12, the storage battery obtaining module 11 is directly connected to the storage battery to obtain the operating parameters of the storage battery, and the uninterruptible power supply obtaining module 12 obtains the operating parameters of the storage battery through the uninterruptible power supply. Further, in this embodiment, the battery obtaining module 11 and the uninterruptible power supply obtaining module 12 are electrically connected to the monitoring module through RS485 respectively. However, the present invention is not limited thereto.
The working principle of the coordinated air-conditioning control system for the battery room of the data center provided by this embodiment is as described in the above step S10 to step S70, and is not repeated again. Similarly, since the heat dissipation has a certain hysteresis, in this embodiment, when the ambient temperature between the batteries is less than the set threshold or the battery discharge is completed, the monitoring module 3 outputs the standby command after delaying for a period of time, and the air conditioner enters the standby state after continuously operating for a certain period of time.
In summary, the data center battery room air conditioner linkage control method and system provided by the invention judge the working state of the storage battery by obtaining the operation parameters of the storage battery, realize the linkage control of the refrigeration air conditioner by obtaining the ambient temperature between the batteries when the storage battery is in the floating charge state, start the refrigeration air conditioner when the ambient temperature between the batteries is greater than or equal to the set threshold value, and enter the standby state when the ambient temperature between the batteries is less than the set threshold value. The monitoring of the ambient temperature between the batteries realizes the linkage control of the refrigeration air conditioner, and the refrigeration air conditioner is prevented from being normally opened while the required temperature of the storage battery refrigeration is ensured, so that the waste of refrigeration energy is greatly reduced, and the purpose of reducing the operation cost of a data center is achieved.
In addition, considering the heat dissipation hysteresis, when the environment temperature between the batteries is monitored to be smaller than a set threshold value, the air conditioner is logically required to continuously run for a period of time and then enter a standby state, so that the influence of heat accumulation on the storage battery is avoided.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
