The following exemplifies a specific implementation procedure of step S1 in the above embodiment.
Referring to fig. 2, a model of the electromechanical assembly machine room equipment is obtained by standardizing parameters of the equipment model and storing the parameters in a database. The model appearance parameters are [ 1081, 600, 852), (0, 300, 450, 75), (75, 300, 852, 75 ].

Referring to table 1, the device model is a database parameter table of the device model, and parameters of a device name, a device number, an external dimension, main technical parameters, and a price are specifically bound in the table.
TABLE 1
Through the specific steps, library construction, parameter input, model recombination, comparative analysis and optimal result output are realized. The following is an example of the specific implementation of steps S2-S3 of the above embodiment.
If the most controlled parameter in the electromechanical assembled machine room to be designed is the price (the most controlled parameter is 1 item), the price is the actual operating equipment parameter. And if the other parameters to be controlled in the electromechanical assembled machine room to be designed are power and floor area, the operating equipment parameters are power and floor area, and range values of the power and the floor area are set.
Setting the range values of power and floor area to be controlled, wherein the power is more than Q watt and the floor area is less than W square meter.
The instructions are set to: the power of the electromechanical assembled machine room to be designed is larger than Q watt and the occupied area is smaller than W square meter, the models in the equipment model database are searched according to the composition of the electromechanical assembled machine room to be designed, the models are combined according to the arrangement logic of the electromechanical assembled machine room to be designed to form a plurality of groups of design models of the electromechanical assembled machine room, and the design models are respectively set as follows with reference to the attached figure 3: model A, model B, model C, model D, model N and model N + 1.
Wherein: the model A, the model B, the model C, the model D, the model N and the model N +1 all accord with the instruction condition that the power is larger than Q watts and the occupied area is smaller than W square meters.
Since the parameter most to be controlled is the price, the optimal design model can be obtained by comparing the prices of a plurality of schemes. The method specifically comprises the following steps: because the model in each assembly machine room is bound with the price parameter, the REVIT software can automatically acquire the whole price of the model A by overlapping the prices of all the component devices in the model A, and can also automatically acquire the whole prices of the model B and other models.
And then comparing the whole price of the model A with the whole price of the model B, and outputting the model A if the whole price of the model A is less than the whole price of the model B.
And comparing the whole price of the model A with the whole price of the model C, and outputting the model C if the whole price of the model C is less than the whole price of the model A.
And comparing the whole price of the model C with the whole price of the model D, and outputting the model C if the whole price of the model C is less than the whole price of the model D.
And comparing the whole price of the model C with the whole price of the model N, and outputting the model N if the whole price of the model N is less than that of the model C.
And comparing the overall price of the model N with the overall price of the model N +1, outputting the model N +1 if the overall price of the model N +1 is less than the overall price of the model N, and obtaining an optimal design model after the comparison of all the models is completed.
According to the specific embodiment of the invention, the method for performing the assembly machine room derivative design based on the REVIT software further comprises S4, decomposing the optimal design model and outputting a CAD drawing. The optimal design model decomposition is understood as: and decomposing the optimal design model into models corresponding to the equipment model library. Through the steps, the material and assembly list of the optimal design model and the corresponding drawing can be obtained, the design achievement can be output quickly, and the design work can be completed.
According to an embodiment of the present invention, in step S1, the corresponding parameters include the size of the model, the equipment operation parameters, the equipment name and the equipment price.

In the embodiment, after the position information of the external interface is marked in the form of three-dimensional coordinates, the position information of the interface can be acquired by software, so that a design model of the electromechanical assembly type machine room is formed. After the information of the size of the interface is provided, the software can select and match the equipment model from the equipment model library according to the size of the interface, and during specific implementation, the size of the external interface can be marked by a radius value or a diameter value, but the radius value or the diameter value is preferably unified into one type, so that the operation efficiency is increased, and the readability is improved.
According to the specific implementation manner of the present invention, the actual operation device parameters are: the water flow required to be reached by the water pump room of the electromechanical assembly type machine room to be designed, or the lift required to be reached by the water pump room of the electromechanical assembly type machine room to be designed, or the refrigerating capacity required to be reached by the refrigerating machine room of the electromechanical assembly type machine room to be designed, or the refrigerant flow required to be reached by the refrigerating machine room of the electromechanical assembly type machine room to be designed, or the price of the electromechanical assembly type machine room to be designed, or the floor area of the electromechanical assembly type machine room to be designed, or the occupied space of the electromechanical assembly type machine room to be designed, or the power of the electromechanical assembly type machine room to be designed.
It should be noted that, in addition to the aforementioned price, the actual operating device parameter of the electromechanical assembled machine room to be designed may also be another parameter, such as the floor space of the electromechanical assembled machine room to be designed or the floor space of the electromechanical assembled machine room to be designed. During specific implementation, the parameters of the operating equipment can be correspondingly selected according to the items to be controlled in the electromechanical assembled machine room to be designed.
During specific implementation, the logic of the components of different electromechanical assembly type machine rooms is different, and the components of equipment required by a cold water machine room, an air conditioner machine room and a fire pump room are different. During combination, the three-dimensional space (0, 0, 0) is taken as a starting point, and related equipment arrangement is carried out from left to right and from top to bottom according to the required equipment combination sequence, so that random combination is carried out.
