Specific embodiment
In conjunction with accompanying drawing, operation principle of the invention is further described.Shown in Fig. 1-Fig. 7, the central air-conditioner monitoring
System is switched to extremum search optimized algorithm, and it is 10 DEG C, concrete operations that the water outlet temperature setting value of handpiece Water Chilling Units is manually adjusted
It is as follows：As shown in figure 3, " freezing water outlet " button is clicked in sign region, as shown in figure 4, ejection main frame chilled water regulation face
Plate picture window, in sign region, is switched to " artificial control " by " Based Intelligent Control ", then in " hand by chilled water outlet temperature
After " manual SP " in a dynamic setting " column is manually entered " 10.0 " with keyboard, enter key comes into force after determining.
The leaving water temperature value setting of handpiece Water Chilling Units is switched to intelligent mode, that is, puts into COP maximum searching algorithms, from
The optimal main frame water outlet temperature setting value of dynamic search；Concrete operations are as follows：As shown in figure 3, clicked in sign region " freezing out
Water " button, as shown in figure 4, ejection main frame chilled water regulation panel picture window, in sign region, by chilled water outlet temperature
" Based Intelligent Control " is switched to by " artificial control ", does not go to change the significant data in parameter setting, can otherwise influence software
Normal operation.As shown in figure 5, the operational effect picture of period is run in whole central air-conditioning for COP maximum searchings algorithm
Face-port mouthful, wherein during a curve is COP, system operation, COP slowly optimizing to optimum value, and when being always maintained at shutting down
Carve, illustrate the validity of algorithm operation, another curve is system power energy consumption curve；As seen from the figure, system operation is whole to the later stage
Physical efficiency consumption declines quickly, and energy-saving effect is obvious.
Operation of the main frame intellectuality team control software in central air-conditioning monitoring system is specific as follows：As shown in fig. 6, click into
Enter " system setting " picture window, into the mode selective region in the upper left corner, system is switched to " intelligent mode ", it is ensured that system
The prerequisite of intelligent team control running software, since it is considered that refrigeration air-conditioner has transition season, therefore general data all can
Configuration size main frame, in the case of the sweltering heat the most of usual weather, system at most needs to open two big main frames；But generally,
System drives a big main frame and a small main frame, and when weather is gradually cooled off oneself, system can slowly be transitioned into holds a big master
Machine, finally untill one small main frame of unlatching.Similarly, when weather slowly becomes sweltering heat, the logic that system is intelligently started shooting is
One small main frame is opened according to heat index, when main frame undercapacity, then big main frame operation is automatically switched to, still exerted oneself not
When enough, then increase a small main frame operation.When any hostdown, system can be automatically switched in backup host,
And phase delay turns off the imported valve of failed host, entirely switching is complete with the process of adding machine by program height intelligence for main frame
Change operation, without human intervention, size main engine power and number of units are run and whole air-conditioning refrigeration duty real-time matching, and cold supply and demand is put down
Weighing apparatus, main frame energy-efficient operation all the time.

Left area " main frame increase service condition " parameter set button in " system setting screen ", into as shown in fig. 7, system is cold
When underload, the temperature phenomenon on water knockout drum is embodied in, is exactly to remain high all the time, and the operation power of main frame connects all the time
Nearly rated power.Therefore, monitor in real time service condition, you can complete the increase operation operation of main frame.When a certain switching condition
When meeting, the lines that red is indicated can automatically switch to green state；When all of condition all meets, all of lines become
Into green；Now system is automatically performed intelligence plus machine program, the parameter of system confirmed as in project debugging it is optimal, typically
It is not recommended that user goes modification.
It is specific as follows that main frame intelligently subtracts operation of the open shop condition in central air-conditioning monitoring system：As shown in fig. 6, mouse
Click left area " main frame the subtracts open shop condition " parameter set button in " system setting screen "；Into as shown in fig. 7, being
When system refrigeration duty is rich, the temperature phenomenon on water knockout drum is embodied in, is exactly that temperature is laid, and also have a little remaining
Amount, and multiple host operation power all the time close to the half of normal rated power, now one main frame energy saving in running of reduction.
When a certain switching condition meets, the lines that red is indicated can automatically switch to green state；When all of condition all meets
When, all of lines become green；Now system is automatically performed intelligence plus machine program, and the parameter of system is in project debugging
