Description

Technical Field

[0001] This invention relates to the field of pump room equipment monitoring technology, specifically a method for arranging sliding rails for monitoring equipment in a nuclear power plant PX pump room. Background Technology

[0002] PX pump houses are short for nuclear power plant auxiliary pump houses. They are a crucial sub-item related to nuclear safety within the supporting facilities of a nuclear power plant, and therefore have high design and construction standards. In actual construction, due to limitations such as geographical location, construction period, and schedule, the construction of PX pump houses and their intake systems often needs to be carried out in winter. Construction of pump houses and related structures in cold weather where the average daily outdoor temperature is below 5°C for five consecutive days requires compliance with numerous regulations and certain construction safeguards to meet the increased structural strength requirements during winter construction.

[0003] Numerous pieces of equipment exist within the PX pump room of a nuclear power plant, many of which are equipped with instruments. The readings on these instruments provide a clear indication of the equipment's safety. Traditionally, this involved manual periodic checks of the instrument readings to determine if the equipment was functioning properly. However, this method has been gradually phased out, replaced by real-time monitoring equipment. Yet, the layout of these monitoring devices in current technology significantly impacts the overall project cost. Furthermore, an inappropriate layout can limit the monitoring range of the instruments, resulting in incomplete data collection. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for arranging the monitoring slide rails of PX pump room equipment in nuclear power plants. This solves the problem that in the prior art, the rationality of the layout of monitoring equipment seriously affects the cost of the entire project. At the same time, an unreasonable layout of monitoring equipment will limit the monitoring range of the instruments, resulting in the inability to obtain comprehensive monitoring data.

[0005] This invention provides a method for arranging monitoring slide rails in a PX pump room of a nuclear power plant, the method comprising the following steps:

[0006] S1. First, measure the internal space dimensions of the nuclear power plant's PX pump room and determine the location of the equipment within the pump room. Then, construct a model of the nuclear power plant's PX pump room on the drawing software and load the equipment within the pump room into the model at a 1:1 scale.

[0007] S2. Simulate different slide rail layout schemes in drawing software, and select the optimal layout scheme for simulation verification;

[0008] S3. Based on the results of the above verification, determine the final slide rail arrangement and define the slide rails into the model according to the slide rail arrangement.

[0009] S4. Construct a monitoring probe model on the slide rail of the overall model, simulate the movement trajectory of the monitoring probe model on the slide rail, and analyze the maximum monitoring range of the monitoring probe.

[0010] S5. Machining the slide rails according to a 1:1 scale, installing the slide rails in the pump room according to the arrangement, and then installing the monitoring probes on the slide rails. After installation, test the data.

[0011] Preferably, the specific content of step 2 is as follows:

[0012] 1) Simulation verification uses a trained deep learning model. A deep learning algorithm is established based on the slide rail trajectory. The obtained feature value coordinates are imported into the deep learning algorithm formula. After importing, the original two-dimensional slide rail image can be generated.

[0013] 2) At the same time, a deep learning model is established based on the deep learning algorithm. The two-dimensional sliding rail image is imported into the deep learning model, and all feature value coordinates are calculated according to the deep learning algorithm. The deep learning model is trained to fuse all feature value coordinates and generate the final three-dimensional sliding rail image.

[0014] Preferably, the specific content of step 4 is as follows:

[0015] The manually drawn sliding track trajectory is imported into the 3D sliding track image. The model compares its own drawn trajectory with the manually drawn trajectory, and then analyzes the difference between the two through a training learning algorithm, and establishes a relevant drawing algorithm based on the training learning algorithm.

[0016] Preferably, the specific content of step 5 is as follows:

[0017] 1) Collect monitoring probe movement data, record relevant parameters of the monitoring probe at corresponding times, and statistically analyze the characteristic values ​​related to time;

[0018] 2) Divide the statistical feature values ​​into segments and set corresponding feature intervals with time parameters as nodes;

[0019] 3) Convert precise quantities into fuzzy single-point sets on the standard universe of discourse, and convert precise quantities into basic elements on the standard universe of discourse through correspondence relations;

[0020] 4) Establish a nonlinear fuzzification model and train a nonlinear fuzzification algorithm;

[0021] 5) Based on the nonlinear fuzzification algorithm, the fuzzy values ​​are inferred and the precise values ​​are determined, and then the final precise quantity output is obtained.

[0022] Compared with existing technologies, the method for arranging monitoring slide rails in nuclear power plant PX pump room equipment of the present invention has the following advantages:

[0023] This invention, through the establishment of models and algorithms, enables the rational layout of slide rails, allowing the monitoring probe to take readings directly in front of the instrument, ensuring that the instrument reading error is minimized within a reasonable range. At the same time, the arrangement of the slide rails maximizes the monitoring range, thereby reducing the number of monitoring devices and saving engineering costs. Attached Figure Description
