In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a performance optimization method for an environmental protection system, including:

When judging whether the total flow resistance of the first pipeline meets the preset flow resistance condition, the parameters of normal temperature and 25L/min flow can be preset, so that the total flow resistance of the first pipeline only needs to be compared with the preset total flow resistance of the preset flow resistance condition.

It should be noted that in this embodiment, in order to make the optimized total flow resistance of the pipeline meet the preset flow resistance condition, it may need to continuously and repeatedly perform iteration attempts, and therefore, the method may be adopted to optimize the ORU and/or the pipeline by a repeated iteration method, and the optimization is not stopped until the optimized total flow resistance of the pipeline meets the preset flow resistance condition.
In the embodiment of the invention, the working flows of all subsystems in an environment-controlled life-saving system of a track device are analyzed, the interconnection relationship of the on-track replaceable component ORUs of each subsystem is determined, at least two ORUs are provided, the first pipeline routing of the pipeline connected with the ORUs is determined according to a preset layout principle and the interconnection relationship of the ORUs, whether the first pipeline total flow resistance of the pipeline meets a preset flow resistance condition or not is judged according to the first pipeline routing, and when the first pipeline total flow resistance does not meet the preset flow resistance condition, the ORUs and/or the pipeline are optimized, so that the optimized pipeline total flow resistance meets the preset flow resistance condition. Because each subsystem of the environment-friendly life support system of the existing track device usually has a large number of gas-liquid pipelines, and the reduction of the flow resistance of the gas-liquid pipelines is the core for optimizing the performance of the subsystems, the invention optimizes the ORU and/or the pipelines to ensure that the optimized total flow resistance of the pipelines meets the preset flow resistance condition, thereby improving the performance of the environment-friendly life support system.

In the embodiment of the invention, after a first pipeline routing of a pipeline connected with an ORU is determined according to a preset layout principle and the mutual connection relation of the ORUs, if the first pipeline routing does not meet a preset flow resistance condition, the pipe diameter and the turning radius of the pipeline are optimized, if the preset flow resistance condition is met after optimization, the ORU is not required to be modified, and if the preset flow resistance condition is not met, the ORU is required to be optimized.
In the above embodiment shown in fig. 3, for the ORU optimization, only the pipeline layout, i.e. the pipeline length, can be changed, so the points of ORU optimization include: the opening direction of the pipeline interface, the position of the pipeline interface and the structure characteristics of the ORU.
From the change difficulty of the ORU optimization, the optimization can be carried out according to the change idea from the detail to the whole, namely, the optimization of the opening direction of the pipeline interface (I) is carried out firstly, when the preset flow resistance condition is not met, the optimization of the position of the pipeline interface (II) is carried out, and when the preset flow resistance condition is not met, the optimization of the structural characteristics of the ORU (III) is carried out. The following examples are provided for illustration of the present invention.
The opening direction of the pipeline interface is aimed at;

405. the preset flow resistance condition is met.
In the embodiment of the invention, the ORU is connected with the pipeline through the pipeline interface, if the opening directions of the pipeline interfaces are different, the pipeline can be bent more when the pipeline is connected, if the opening direction of the pipeline interface is changed to the same direction, the bending of the pipeline can be reduced, whether the preset flow resistance condition is met or not is judged through the flow resistance analysis of the second pipeline routing, if the preset flow resistance condition is met, the flow resistance can be reduced only by changing the opening direction of the pipeline interface, and the method is easy to realize.
(II) optimizing the position of the pipeline interface;

Although changed the overall structure of ORU in this embodiment, but can reduce pipeline length, reduce pipeline total flow resistance, can also carry out the planning of different kinds of interfaces to the more ORU of interface simultaneously, the convenient wiring.
In addition to the change of the structural characteristics of the ORU in the embodiment shown in fig. 6, the original ORU may be split to obtain a plurality of sub-assemblies, so as to rearrange the positions and pipe interfaces of the sub-assemblies, and in conjunction with the embodiment shown in fig. 5, step 504 in fig. 5 is described below with the embodiment shown in fig. 7, specifically:

703. judging whether the total flow resistance of the sixth pipeline is greater than the preset total flow resistance or not; if so, the preset flow resistance condition is not met; if the flow resistance is smaller than or equal to the preset flow resistance condition, the preset flow resistance condition is met.
In the embodiment of the invention, under the condition that the opening direction and the position of the pipeline interface of the ORU are changed and the preset flow resistance condition cannot be met, the structural characteristics of the ORU are required to be changed, the ORU is divided into at least two sub-assemblies, the installation position of each sub-assembly is set, the position of the pipeline interface of each sub-assembly is specified, and the fifth pipeline routing is obtained. The split has been carried out ORU in this embodiment, and although the design modification is great, the subassembly that the split was gone out can reset on the position overall arrangement for the position of pipeline interface also can reset, and it is very convenient to walk the line to new pipeline, and the total flow resistance of reduction pipeline that can be better satisfies preset flow resistance condition.
It should be noted that, because the number of ORUs is large, the optimization changes of each ORUs, the position of the pipeline interface of each ORUs, and the opening direction of the pipeline interface of each ORU may have a large influence on the total flow resistance of the pipeline, and therefore, iteration common knowledge needs to be continuously and repeatedly performed.
