Please refer to Fig. 1, the flow chart of a kind of cold medium shortage processing method that Fig. 1 provides for the embodiment of the present invention.The cold medium shortage processing method that the embodiment of the present invention provides comprises the following steps:
Whether step 11: when cold medium shortage appears in described humidity control system, judge to exist in described N platform off-premises station and can load and off-duty P platform off-premises station, and P is the integer being more than or equal to 1 and being less than N;
Step 12: can load and off-duty P platform off-premises station if exist, then load now off-duty in described P platform off-premises station and the off-premises station that priority is the highest;
Step 13: can load if do not exist and off-duty P platform off-premises station, then unload one running and the off-premises station that priority is the highest, and load an off-duty and off-premises station that priority is the highest, then priority rotation carried out to described N platform off-premises station.
Judge in step 11 whether to exist in described N platform off-premises station and can load and off-duty P platform off-premises station, be specially:
Judge whether the off-premises station target capability allocation proportion in the off-premises station run is greater than default allocation proportion, and described default allocation proportion is corresponding with the number of units of the off-premises station run; If the off-premises station target capability allocation proportion in the off-premises station run is greater than default allocation proportion, then show that existence can load and off-duty P platform off-premises station;
Judge whether the off-premises station target capability allocation proportion in the off-premises station run is less than default allocation proportion, and described default allocation proportion is corresponding with the number of units of the off-premises station run; If the off-premises station target capability allocation proportion in the off-premises station run is less than default allocation proportion, then shows not exist and can load and off-duty P platform off-premises station.
Specifically, existence can load and off-duty P platform off-premises station refers to: have off-premises station in operation, the number of units of the off-premises station of operation is less than N, and the off-premises station target capability allocation proportion in the off-premises station run is greater than default allocation proportion.
Do not exist and can to load and off-duty P platform off-premises station has and is not limited to following situation:
Have off-premises station in operation, the number of units of the off-premises station of operation is less than N, and the off-premises station target capability allocation proportion in the off-premises station run is less than default allocation proportion.
Calculate the off-premises station target capability allocation proportion OTC_Ratio of the off-premises station run, if OTC_Ratio is greater than default allocation proportion, then can load an off-premises station, from off-duty off-premises station, particularly select an off-premises station that priority is the highest to load.
Wherein,
sTC is current goal system capability, the target capability of the system cloud gray model namely after humidity control system start.Preset allocation proportion different with the difference of the off-premises station number of units run.
If OTC_Ratio is less than default allocation proportion, then need unloading off-premises station, from the off-premises station run, particularly select an off-premises station that priority is the highest to unload, from off-duty off-premises station, select an off-premises station that priority is the highest to load again, then rotation is carried out to the priority of N platform off-premises station.Preset allocation proportion different with the difference of the off-premises station number of units run.
Assumed temperature regulating system has 4 off-premises stations, be respectively off-premises station 1, off-premises station 2, off-premises station 3, off-premises station 4, suppose that off-premises station 1 is in operation, and off-premises station 2 to off-premises station 4 all off-duties, then judge whether the OTC_Ratio of off-premises station is more than or equal to 30%, if be more than or equal to 30%, then can load an off-premises station, because the priority of off-premises station 2 in off-premises station 2 to off-premises station 4 is the highest, so load off-premises station 2.If OTC_Ratio is less than 30%, then need the off-premises station that unloading priority run is the highest, owing to only having off-premises station 1 in operation, so unloading off-premises station 1; Load an off-duty and the highest off-premises station of priority, because the priority of off-premises station 2 in off-premises station 2 to off-premises station 4 is the highest, so load off-premises station 2, then carry out priority rotation, the priority of off-premises station 1, off-premises station 2, off-premises station 3, off-premises station 4 is respectively 4,1,2,3.
If have two off-premises stations in operation, suppose that off-premises station 1 and off-premises station 2 are in operation, and off-premises station 3 and off-premises station 4 off-duty, then judge whether off-premises station OTC_Ratio is more than or equal to 35%, if be more than or equal to 35%, then can load an off-premises station, then load off-premises station 3.If OTC_Ratio is less than 35%, then need the off-premises station that unloading priority run is the highest, because the priority of off-premises station 1 in off-premises station 1 and off-premises station 2 is the highest, so unloading off-premises station 1; Load an off-duty and the highest off-premises station of priority, because the priority of off-premises station 3 in off-premises station 3 and off-premises station 4 is the highest, so load off-premises station 3, then carry out priority rotation, the priority of off-premises station 1, off-premises station 2, off-premises station 3, off-premises station 4 is respectively 4,1,2,3.
If have three off-premises stations in operation, suppose that off-premises station 1 and off-premises station 2 and off-premises station 3 are in operation, and off-premises station 4 off-duty, then judge whether off-premises station OTC_Ratio is more than or equal to 40%, if be more than or equal to 40%, then can load an off-premises station, then load off-premises station 4.If OTC_Ratio is less than 40%, then need the off-premises station that unloading priority run is the highest, because the priority of off-premises station 1 in off-premises station 1 and off-premises station 2 and off-premises station 3 is the highest, so unloading off-premises station 1; Load an off-duty and the highest off-premises station of priority, i.e. off-premises station 4, then carries out priority rotation, and the priority of off-premises station 1, off-premises station 2, off-premises station 3, off-premises station 4 is respectively 4,1,2,3.
After loading off-premises station or after unloading off-premises station, need to recalculate OTC_Ratio and OTC, wherein, the rated capacity of OTC=off-premises station is multiplied by OTC_Ratio, then the OTC calculated is distributed to eachly running and loading but off-duty off-premises station.
