s201, judging whether the using data is smaller than a first preset threshold value or not and whether the first duration time reaches a preset duration time or not; if yes, go to step S202; if not, go to step S203.
If the control type information indicates energy saving control, it is necessary to determine whether the usage data is smaller than a first preset threshold and whether the first duration time reaches a preset time. Assume that the usage data is x%, the first preset threshold is a%, the first duration is T1, and the preset duration is T. That is, it is necessary to determine whether x% < a% and T1 ≧ T are satisfied. Wherein the first duration T1 is a duration for which the usage data is less than a first preset threshold (x% < a%).

And if the use data is judged to be smaller than the first preset threshold value and the first duration reaches the preset duration (namely x% < a% and T1 is larger than or equal to T), determining the first control information of the cooling equipment as the refrigeration control information. Wherein the first control information includes: the refrigeration mode is a natural ventilation mode, and the proportion of the refrigerating capacity is zero (namely 0%).
S203, judging whether the using data is larger than a second preset threshold value and whether the second duration time reaches a preset time; if yes, go to step S204; if not, go to step S205.
If the usage data is determined to be not less than the first preset threshold (i.e., x% ≧ a%) or the first duration does not reach the preset duration (i.e., T1 < T), it is determined whether the usage data is greater than the second preset threshold and the second duration reaches the preset duration. Assuming that the second preset threshold is b%, the second duration is T2. That is, it is necessary to determine whether x% > b% and T2 ≧ T are satisfied. Wherein the second duration T2 is a duration for which the usage data is greater than a second preset threshold (x% > b%). The second preset threshold b% is preferably set to 90%. In this embodiment, the user may adjust the second preset threshold b% according to actual requirements.
And S204, determining second control information of the cooling equipment as cooling control information.
And if the usage data is judged to be larger than the second preset threshold value and the second duration time reaches the preset time (namely x% > b% and T2 is larger than or equal to T), determining second control information of the cooling equipment as the refrigeration control information. Wherein the second control information includes: the refrigerating mode is a refrigerating machine refrigerating mode, and the refrigerating capacity proportion is a complete proportion (namely 100%).

If the usage data is judged to be not greater than a second preset threshold (namely a% is greater than or equal to x% is greater than or equal to b%) or the second duration time does not reach the preset time (namely T2 is less than T), the water supply temperature and the water return temperature in the cold supply process of the cold supply equipment need to be obtained, the temperature difference between the water supply temperature and the water return temperature is calculated, then the PID adjusting technology is utilized, the first target proportion is determined according to the temperature difference to serve as the refrigerating capacity proportion, and therefore third control information of the cold supply equipment is determined to serve as refrigerating control information. Wherein the third control information includes: the refrigeration mode is a cold machine refrigeration mode, and the refrigeration capacity proportion is a first target proportion calculated by utilizing a PID (proportion integration differentiation) adjusting technology according to the temperature difference between the water supply temperature and the return water temperature. In the embodiment, according to the temperature difference between the water supply temperature and the water return temperature, PID adjustment for refrigeration by the refrigerator can be realized by those skilled in the art according to a PID adjustment method in the prior art, and the embodiment is not specifically described.
Further, fig. 3 is a flowchart provided by another embodiment of the method for controlling cooling equipment in a data center room of the present invention, and as shown in fig. 3, in the method for controlling cooling equipment in a data center room of the present embodiment, when the control type information indicates accurate control, the specific steps of step S103 are as follows:
s301, judging whether the use data is smaller than a third preset threshold value and whether the third duration time reaches a preset time; if yes, go to step S302; if not, go to step S303.
If the control type information indicates accurate control, it is necessary to determine whether the usage data is smaller than a third preset threshold and whether a third duration time reaches a preset time. Assume that the usage data is x%, the third preset threshold is c%, the third duration is T3, and the preset duration is T. That is, it is necessary to determine whether x% < c% and T3 ≧ T are satisfied. Wherein the third duration T3 is a duration for which the usage data is less than a third preset threshold (x% < c%). The third preset threshold c% is preferably set to 15% and the preset duration T is preferably set to 3 minutes. In this embodiment, the user may adjust the third preset threshold c% and the preset duration T according to actual requirements.
S302, determining first control information of the cooling equipment as cooling control information.
And if the use data is judged to be smaller than the third preset threshold value and the third duration time reaches the preset time (namely x% < c% and T3 is larger than or equal to T), determining the first control information of the cooling equipment as the refrigeration control information. Wherein the first control information includes: the cooling mode is a natural ventilation mode, and the cooling capacity proportion is zero proportion (namely 0%).
S303, judging whether the using data is larger than a fourth preset threshold value and whether the fourth duration reaches a preset duration; if yes, go to step S304; if not, step S305 is executed.
If the usage data is judged to be not less than the third preset threshold (i.e. x% ≧ c%) or the third duration does not reach the preset duration (i.e. T3 < T%), it is necessary to continuously judge whether the usage data is greater than the fourth preset threshold and whether the fourth duration reaches the preset duration. Assuming that the fourth preset threshold is d%, the fourth duration is T4. That is, it is necessary to determine whether x% > d% and T4 ≧ T are satisfied. Wherein the fourth duration T4 is a duration for which the usage data is greater than a fourth preset threshold (x% > d%). The fourth preset threshold value d% is preferably set to 30%. In this embodiment, the user may adjust the fourth preset threshold d% according to actual requirements.
And S304, determining fourth control information of the cooling equipment as refrigeration control information according to the preset mapping function and the use data.
If the usage data is larger than the fourth preset threshold and the fourth duration time reaches the preset time (i.e., x% > d% and T4 ≧ T), fourth control information of the cooling device needs to be determined as the refrigeration control information according to the preset mapping function and the usage data. The preset mapping function is a linear function, for example, y ═ kx + b, where k and b are preset parameters, x is input use data, y is a calculated second target proportion, and k and b can be set according to actual requirements. In the embodiment, a preset mapping function is used to determine a second target proportion corresponding to the usage data as the refrigeration capacity proportion. The fourth control information includes: the refrigeration mode is a cold machine refrigeration mode, and the refrigeration capacity proportion is a second target proportion calculated according to a preset mapping function and the use data.
And S305, determining third control information of the cooling equipment as cooling control information.
If it is determined that the usage data is not greater than the fourth preset threshold (i.e., c% ≦ x% ≦ d%) or the fourth duration does not reach the preset duration (i.e., T4 < T), it is necessary to determine the third control information of the cooling apparatus as the cooling control information. The determination manner of the third control information in this embodiment is the same as that of step S205, and this embodiment is not specifically described again.
