[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0045] First, some nouns involved in this application are analyzed:

[0046] Drum network: The drum network is an important key equipment of the circulating water filtration system CFI of the nuclear power plant with seawater direct current cooling. It provides sufficient water for the nuclear power plant's important safety water system SEC and the circulating water system CRF. As a large-scale filtration equipment to resist marine organisms in the nuclear power plant's cold source "defense in depth" system, it is an important equipment to ensure that the cold chain water quality of the entire plant meets the operation requirements.

[0047] At present, the drum filter of nuclear power plants is mainly divided into two types, one is the "inside out" type, and the other is the "outside inside out" type. Through the experience feedback of the ability of the two types of drum nets in the operating nuclear power plants to defend against the invasion of marine organisms, the "inside out" type drum net has a weak impact load resistance, and the "outside inside out" type drum net has obvious advantages in marine organism resistance and prevention and control. The diameter of the drum net body of the coastal nuclear power plant is about 18m-22m. The size and structure are different according to the scale of the power plant. The drum net body rotates and runs alternately in the seawater above and underwater environment. The main shaft structure runs underwater most of the time. The working environment is harsh, and it is easy to breed various marine organisms and rust. Under extreme marine conditions, it is more susceptible to large debris and a large number of marine organisms. Accumulation, which may cause damage to the main structure of the equipment, rust on the filter surface, and thus lose the filtering function. In severe cases, it may cause the power plant to lose its cold source and threaten nuclear safety.

[0048] In recent years, nuclear power plants have experienced shutdown and reactor shutdown safety incidents due to blockage by marine organisms, which has attracted great attention from all parties. Such cold source incidents have a great impact on the drum network itself, and the operation and maintenance of nuclear power plants have put forward an urgent need to obtain the health status of the drum network.

[0049] At present, the power plant's drum net lacks a systematic online status monitoring system. The power plant currently monitors the drum net's filtering capacity through the water level pressure difference inside and outside the drum net to ensure sufficient water for cooling the nuclear power plant. When the drum net is operating normally at low speed, the alarm linkage of large water level pressure difference starts the medium and high speed motor to increase the speed and filtering capacity. When the maximum design load is exceeded, the water level is high and the fault is shut down. In order to maintain the health of the equipment, the power plant regularly conducts manual inspections such as appearance, abnormal noise and structural corrosion on the operation of each component of the drum net body. After abnormal noise or fault problems are found, temporary tool detection of local parameters such as radial runout and vibration of the mesh surface is carried out. After accidents and faults occur, the drum net body is evaluated based on personnel experience. At the same time, due to the harsh operating environment of the drum net, higher requirements are placed on the monitoring technology used by the body and the sensing equipment installed on the body.

[0050] The existing manual offline detection method of the drum network body cannot collect the slow performance degradation of the drum network caused by corrosion, cold source events, assembly, design / equipment inherent defects and operation under over-design conditions. The potential hidden dangers before the failure cannot be perceived, and it is impossible to provide information for the intelligent needs of the drum network such as fault diagnosis and early warning. It is not conducive to fault judgment and determination of maintenance plans. It is difficult to fully and timely discover the causes of equipment failures, which is not conducive to the safe and economical operation of nuclear power plant units and cannot meet the strategic development needs of the intelligent and information-based transformation of nuclear power plants.

[0051] Based on this, the embodiments of the present application provide a drum network security data display system, method and device, which aim to realize the real-time display of drum network data.

In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0057] like Figure 1 As shown, a drum net safety data display system provided by an embodiment of the present application includes a drum net safety data sensing unit 100 and a drum net safety data display unit 200, wherein the drum net safety data sensing unit 100 is used to sense the drum net safety data generated by the rotation of the drum net main body component 300, a communication connection is established between the drum net safety data display unit 200 and the drum net safety data sensing unit 100, and the drum net safety data display unit 200 is used to display the drum net safety data.

[0058] like Figure 2 and Figure 3 As shown, the drum net main body component 300 includes a driving component 310, a drum net frame 320 and a main shaft component 330, wherein the driving component 310 is used to drive the drum net frame 320 to rotate around the main shaft component 330, wherein the main shaft component 330 is the center of rotation of the drum net frame 320.

[0059] In detail, when the driving assembly 310 is powered, the driving assembly 310 drives the drum mesh frame 320 to rotate through gear meshing, and the drum mesh frame 320 drives the main shaft assembly 330 to rotate through welding, pin or rivet connection.

[0060] Furthermore, the spindle assembly 330 includes a spindle bearing 331 and a spindle bearing seat 332 connected to the spindle bearing 331 , and the spindle bearing seat 332 includes a limiting pull rod 333 .

[0061] The limiting pull rod 333 can limit the main shaft assembly 330 when the water pressure difference between the inside and outside of the drum net main assembly 300 exceeds the designed pressure difference threshold, thereby avoiding damage to the drum net main assembly 300.

[0062] It should be noted that when the driving assembly 310 is powered, in the main shaft assembly 330 , the main shaft bearing seat 332 is fixed, and the main shaft bearing 331 rotates with the rotation of the drum net frame 320 .

[0063] Furthermore, the drum net safety data sensing unit 100 includes a first sensor component 110 and a second sensor component 120 . It should be noted that the first sensor component 110 is disposed on the surface of the drum net frame 320 , and the second sensor component 120 is disposed on the surface of the main shaft bearing seat 332 .

[0064] Among them, the first sensor component 110 includes a drum mesh radial displacement sensor 111 and a drum mesh axial displacement sensor 112 perpendicular to the drum mesh radial displacement sensor 111. The drum mesh radial displacement sensor 111 is used to monitor the radial displacement of the drum mesh skeleton 320, and the drum mesh axial displacement sensor 112 is used to monitor the axial displacement of the drum mesh skeleton 320. In addition, the drum mesh radial displacement sensor 111 and the drum mesh axial displacement sensor 112 can also be used in combination, and the drum mesh radial displacement sensor 111 and the drum mesh axial displacement sensor 112 can realize real-time monitoring of the drum mesh skeleton 320 by using them in combination, so that the nuclear power plant monitoring personnel can obtain the fault status of the drum mesh skeleton 320 in real time.

[0065] It should be noted that deformation of the drum net skeleton 320 caused by operation at beyond-design conditions or failure of the main structural components of the main body will cause excessive side clearance of the mesh surface of the drum net skeleton 320, resulting in a reduction in the interception rate of the drum net skeleton 320 or causing the drum net skeleton 320 to shut down or stop the reactor. Therefore, a drum net surface radial displacement sensor 111 and a drum net surface axial displacement sensor 112 are provided on the drum net skeleton 320, which can monitor the radial displacement and axial displacement of the drum net skeleton 320 in real time, and thereby realize the monitoring of the deformation of the drum net skeleton 320. For example, when the radial displacement of the drum net skeleton 320 monitored by the drum net surface radial displacement sensor 111 and the drum net surface axial displacement sensor 112 exceeds a preset radial displacement threshold, and / or the axial displacement exceeds a preset axial displacement threshold, it can remind maintenance personnel or relevant personnel of the nuclear power plant to take effective countermeasures for the current situation.

[0066] like Figure 4 As shown, the second sensor component 120 includes a drum net main shaft limit rod bolt preload force sensor 121, a drum net main shaft bearing seat vibration sensor 122, a drum net main shaft displacement sensor 123, a drum net main shaft key phase monitoring sensor 124 and a drum net main shaft encoder 125.

[0067] In some embodiments, the drum net main shaft limit rod bolt preload force sensor 121 can timely understand the influence of the pressure difference between the inside and outside of the mesh surface of the drum net skeleton 320 on the stress of the limit rod 333 by monitoring the stress state of the limit rod 333, and send the monitored information of the limit rod 333 to the monitoring personnel of the drum net skeleton 320 before the limit rod 333 breaks, so as to protect the safety of the drum net skeleton 320.

[0068] In some embodiments, the drum net main shaft bearing seat vibration sensor 122 can timely understand the working condition of the main shaft bearing seat 332 by monitoring the vibration condition of the main shaft bearing seat 332, and when the vibration condition of the main shaft bearing seat 332 does not meet the expected vibration data, the monitored vibration condition of the main shaft bearing seat 332 is sent to the monitoring personnel of the drum net frame 320 to protect the safety of the drum net frame 320.

[0069] In some embodiments, the drum net main shaft displacement sensor 123 can obtain the trajectory of the axis of the main shaft bearing 331 by monitoring the displacement of the main shaft bearing 331, so that the monitoring personnel of the drum net skeleton 320 can find the misalignment of the main shaft assembly 330 caused by manufacturing and installation problems of the drum net skeleton 320 based on the trajectory of the axis of the main shaft bearing 331.

[0070] In some embodiments, a convex point is set on the main shaft bearing 331 as a reference point, and the position change of the convex point is monitored by the drum net main shaft key phase monitoring sensor 124, so that the eccentricity and vibration phase of the main shaft assembly 330 can be obtained, and then according to the convex point and the drum net main shaft encoder 125, the technical pulse value and rotation direction of the main shaft assembly 330 can be obtained. Based on the eccentricity, vibration phase, technical pulse value and rotation direction of the above-mentioned main shaft assembly 330, the rotation speed and rotation angle of the main shaft bearing 331 can be calculated. In addition, the monitoring personnel of the drum net skeleton 320 can locate the fault of the drum net main body assembly 300 based on the rotation state such as the rotation speed and rotation angle of the main shaft bearing 331.

[0071] like Figure 5 As shown, a drum network security data display system provided by an embodiment of the present application, the drum network security data display unit 200 includes a drum network security data conversion module 210, a drum network security data processing module 220 and a drum network security data visualization module 230, the drum network security data conversion module 210 is used to convert the drum network security data into drum network security digital data, to realize the collection of drum network security data, the drum network security data processing module 220 establishes a communication connection with the drum network security data conversion module 210, the drum network security data processing module 220 is used to store the drum network security digital data, and convert the drum network security digital data into drum network security format data, the drum network security data visualization module 230 establishes a communication connection with the drum network security data processing module 220, and the drum network security data visualization module 230 is used to display the drum network security format data.

[0072] In some embodiments, the drum network safety data processing module 220 can be used to perform eigenvalue analysis and eigenvalue calculation on the drum network safety data sensed by the first sensor component 110 and the second sensor component 120, so as to reduce the time of drum network safety data transmission and improve the timeliness of drum network safety data.

[0073] In some embodiments, the drum network safety data visualization module 230 can display the drum network safety data sensed by the first sensor component 110 and the second sensor component 120 in an expression form preset by the monitoring personnel.

[0074] Figure 6 is a flow chart of a drum network security data display method provided in an embodiment of the present application, which can be applied to the above-mentioned drum network security data display system. Figure 6 The method may include but is not limited to steps S601 to S605.

Secondly, the drum network safety data conversion module 210 is used to perform analog-to-digital conversion on the drum network safety simulation data to obtain drum network safety digital data, and then the drum network safety data processing module 220 is used to format the drum network safety digital data to obtain drum network safety format data. Finally, the drum network safety data visualization module 230 is used to visualize the drum network safety format data to display the drum network safety data to the staff of the nuclear power plant. Therefore, the present application can generate drum network safety data by operating the drum network safety data excitation unit 100, and then use the drum network safety data perception unit 100 to monitor the drum network safety data to obtain drum network safety simulation data, thereby realizing real-time detection of the drum network safety data. Furthermore, the drum network safety data processing module 220 is used to perform analog-to-digital conversion on the drum network safety simulation data to obtain drum network safety digital data, thereby realizing the collection of drum network safety data.

Finally, the drum network safety data visualization module 230 is used to display the drum network safety format data, thereby realizing real-time observation of the drum network safety data by nuclear power plant staff.

[0081] In one application scenario, taking the setting of a sensor on the drum net 112 as an example, by setting a sensor on the drum net main body component 300, real-time monitoring of the drum net main body component 300 is achieved, and then the drum net safety data monitored by the sensor is converted into analog to digital through the analog to digital conversion device to obtain drum net safety digital data in digital format, thereby realizing the collection of drum net safety data. Furthermore, the drum net safety data processing module 220 is used to perform data formatting and data storage processing on the drum net safety digital data to obtain drum net safety format data.

Finally, the drum net safety format data to be displayed is displayed to the drum net safety data visualization module 230.

When the drum net frame 320 rotates, the drum net frame 320 drives the main shaft assembly 330 to rotate through welding, latches or rivet connections, thereby forming drum net safety data.

[0092] In step S701 and step S702 of some embodiments, the drum net surface radial displacement sensor 111 and the drum net surface axial displacement sensor 112 can obtain the drum surface radial displacement data by monitoring the radial displacement of the drum net skeleton 320, and obtain the drum surface axial displacement data by monitoring the axial displacement of the drum net skeleton 320, thereby realizing the monitoring of the deformation of the drum net skeleton 320 caused by operation beyond the design condition or failure of the main structural components of the main body. Furthermore, when the drum surface radial displacement data and the drum surface axial displacement data exceed the set threshold value, the monitoring personnel of the nuclear power plant can be promptly reminded to take effective countermeasures to prevent the overall structural deformation of the drum net skeleton 320 from being too large, resulting in excessive side clearance of the net surface, affecting the interception rate and possibly causing shutdown of the drum net skeleton 320.

The drum net main shaft bearing seat vibration sensor 122 is used to monitor the vibration condition of the main shaft bearing seat 332, and timely understand the working condition of the main shaft bearing seat 332. Specifically, the drum net main shaft limit tie rod bolt preload force sensor 121 obtains the limit tie rod stress data by monitoring the stress state of the limit tie rod 333, and the drum net main shaft bearing seat vibration sensor 122 obtains the bearing seat vibration data by monitoring the vibration state of the main shaft bearing seat 332.

[0094] In step S705 of some embodiments, the radial displacement of the main shaft bearing 331 is monitored by using the drum net main shaft displacement sensor 123 to obtain the main shaft displacement data.

[0095] In step S706 of some embodiments, the drum net spindle key phase monitoring sensor 124 obtains the spindle key phase data by monitoring the eccentricity and vibration phase of the spindle assembly 330, and the drum net spindle encoder 125 obtains the spindle speed data and the spindle count data by recording the number of rotations and the rotation direction of the spindle assembly 330. The above-mentioned spindle key phase data, spindle speed data and spindle count data are merged to obtain the spindle rotation data. It should be noted that the drum net spindle key phase monitoring sensor 124 and the drum net spindle encoder 125 can be used in combination to realize fault monitoring and fault location of the drum net skeleton 320 and the spindle assembly 330, so as to improve the efficiency of solving faults of the drum net main assembly 300.

[0096] In step S707 of some embodiments, by combining drum surface radial displacement data, drum surface axial displacement data, limit pull rod stress data, bearing seat vibration data, spindle displacement data, spindle key phase data and spindle rotation data, drum net safety simulation data for representing the safety status of the drum net main body assembly 300 can be obtained.

[0098] In step S603 of some embodiments, the drum network safety analog data is converted into drum network safety digital data by the drum network safety data conversion module 210, which can improve the readability of the data and thus realize the collection of drum network safety data.

[0099] In step S604 of some embodiments, the drum network safety data processing module 220 can perform data formatting and data storage processing on the drum network safety digital data to obtain drum network safety format data. If the nuclear power plant monitoring personnel need to promptly understand the collected drum network safety digital data, the drum network safety data processing module 220 can be used to perform data analysis on the drum network safety digital data, extract characteristic information from the drum network safety digital data, and display the characteristic information to the nuclear power plant monitoring personnel.

[0100] In step S605 of some embodiments, the drum network safety format data is visualized to display the drum network safety format data, so that the nuclear power plant monitoring personnel can observe the working status of the drum network main assembly 300 in time.

[0101] The drum network safety data display system, method and device provided in the embodiment of the present application can generate drum network safety data by operating the drum network safety data excitation unit 100, and then use the drum network safety data perception unit 100 to monitor the drum network safety data to obtain drum network safety simulation data, thereby realizing real-time detection of the drum network safety data. Furthermore, the drum network safety data processing module 220 is used to perform analog-to-digital conversion on the drum network safety simulation data to obtain drum network safety digital data, thereby realizing the collection of drum network safety data. The drum network safety data processing module 220 is then used to format the drum network safety digital data to obtain drum network safety format data, thereby obtaining formatted drum network safety data.
