A power equipment operation fault control system and operation method thereof

Abstract

A power equipment operational fault management and control system and its operating method include a plurality of node devices and a plurality of single-threaded control units arranged in a one-to-one correspondence. This arrangement enables the synchronous collection and processing of single-line operational parameter information corresponding to a single or multiple node devices. The system then automatically controls and adjusts operational protection elements by retrieving adjustment signals, performing self-adjustment of initial faults. Subsequently, by determining the duration of self-adjustment, the system controls the associated detection unit to perform fault screening operations. A secondary analysis and arrangement of node device parameter information is then performed to identify operational protection elements that may be experiencing faults. The system then collects operational and environmental parameters of the operational protection elements, performs image normalization fault screening, and correlates these parameters with environmental parameters for analysis and judgment, ultimately determining the faulty element that may be experiencing a fault. Therefore, this design not only ensures smooth system operation, but also stable and efficient operation.

Description

Technical Field

[0001] The present invention relates to a fault management and control system and an operating method thereof, belonging to the field of power management and control, and in particular to a power equipment operation fault management and control system and an operating method thereof. Background Art

[0002] Power equipment is an electricity production and consumption system consisting of power generation, transmission, transformation, distribution and consumption. It converts primary energy from nature into electricity through power generation devices, and then supplies electricity to users through transmission, transformation and distribution. It mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, hydraulic turbines, generators, motors, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, etc.

[0003] Most of the power management and control systems in existing equipment use real-time monitoring and integration to determine component failures. Since they need to collect, analyze and process data at the same time, the system operation is congested, resulting in detection and operation jams. At the same time, large amounts of data flow can easily cause high storage pressure, making it impossible to implement low-computing and partitioned regular maintenance of node devices, and unable to ensure stable and efficient operation of the system.

[0004] The information disclosed in this background technology section is only intended to increase understanding of the overall background of the application and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in this field. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects and problems of the prior art in terms of system operation jams, low operation stability and efficiency, and to provide an electric power equipment operation fault control system and its operation method with smooth, stable and efficient system operation.

[0006] To achieve the above objectives, the technical solution of the present invention is: a power equipment operation fault management and control system, the management and control system includes a plurality of node devices and a plurality of single-threaded management and control units;

[0007] The plurality of node devices are connected to the plurality of single-threaded control units in a one-to-one correspondence;

[0008] The node device includes a detection sensing element, an operation protection element and an environment adjustment element; the single thread control unit includes a thread collection unit, a thread self-checking unit and an associated detection unit;

[0009] The detection sensing element is used to detect the operating parameter information of the node device; the operation protection element is used to perform retrieval and self-adjustment; the environmental adjustment element is used to adjust the environmental parameters;

[0010] The thread collection unit is used to collect the operating parameter information of the node device detected by the detection sensing element and send it to the thread self-test unit;

[0011] The thread self-check unit is used to receive the operating parameter information of the node device sent by the thread acquisition unit and control the operation protection element to perform a retrieval and self-adjustment operation, and then send the operating parameter information of the node device that may fail to the association detection unit;

[0012] The association detection unit is used to receive the operating parameter information of the node device that may fail sent by the thread self-check unit, perform fault screening, and then control the environment adjustment element to perform environment adjustment operations to analyze and determine the source of the fault.

[0013] An operating method of a power equipment operation fault management and control system, the operating method comprises the following steps:

[0014] S1. The detection sensing element detects operating parameter information of the node device, collects the information through the thread collection unit, and sends the information to the thread self-checking unit. The thread self-checking unit receives the information and performs double normalization processing on the information to determine whether a retrieval adjustment signal is generated. If a retrieval adjustment signal is generated, the operation protection element is controlled to perform a retrieval self-adjustment operation and determine whether the node device may have a fault. If it is determined that a fault may have occurred, the operating parameter information of the node device is sent to the association detection unit to proceed to step S2.

[0015] S2. After receiving the information, the associated detection unit performs secondary analysis and sorting to mark the operating protection components that may have faults as components to be tested. The associated detection unit then collects the operating parameters and environmental parameters of the components to be tested to perform fault screening and determine whether the components to be tested have faults. If the components to be tested have not faulted, the associated detection unit performs fault screening using an image normalization method and associates the environmental parameters with the environmental adjustment components to perform environmental adjustment operations to analyze and determine the source of the fault.

[0016] In step S1, the steps of double normalization processing are:

[0017] S11. After receiving the operating parameter information of the node device, the thread self-check unit compares the operating parameter information of the node device with the corresponding preset threshold range, where the preset threshold range is the operating parameter range value of the node device under normal working conditions; the comparison result includes any one of the following:

[0018] The first type: if the operating parameter information of the node device is within the preset threshold range, then the node device is not faulty;

[0019] The second method: if the operating parameter information of the node device is outside the preset threshold range, proceed to step S12;

[0020] S12. If the operating parameter information of the node device is less than the minimum value of the preset threshold range, the minimum value of the preset threshold range is subtracted from the operating parameter information of the corresponding node device, and then the difference after the subtraction is multiplied by the corresponding weight parameter 1, and finally the products are summed and averaged to obtain the limit minimum mean;

[0021] If the operating parameter information of the node device is greater than the maximum value of the preset threshold range, the maximum value of the preset threshold range is subtracted from the operating parameter information of the corresponding node device, and then the difference after the subtraction is multiplied by the corresponding weight parameter 2, and then the products are summed and averaged to obtain the maximum mean value of the limit;

[0022] Finally, the limit minimum mean and the limit maximum mean are compared with the preset limit threshold range respectively. If the limit minimum mean and the limit maximum mean are both outside the preset limit range, a search adjustment signal is generated;

[0023] In step S1, the steps of performing the retrieval self-adjustment operation and determining whether the node device may have a fault are as follows:

[0024] S13, after the retrieval adjustment signal is generated, the retrieval self-adjustment operation is performed to control the running protection element to perform automatic adjustment;

[0025] S14. After the automatic adjustment is completed, the duration of the adjustment of the operating protection element is obtained, and the duration is compared with a preset duration, where the preset duration is the duration expected to be taken by the operating protection element to complete the automatic adjustment. The comparison result includes any one of the following:

[0026] The first type: if the duration is less than the preset duration, the operating parameter information of the node device is not sent to the association detection unit;

[0027] The second type: if the duration is greater than or equal to the preset duration, the node device may fail, and the operating parameter information of the node device is sent to the association detection unit.

[0028] In step S2, the steps of performing fault screening are:

[0029] S21. After receiving the operating parameter information of the node device, the associated detection unit arranges the data in descending order, obtains the operating protection element corresponding to the largest data, and marks it as the element to be detected;

[0030] S22. Collect the operating parameters and environmental parameters of the component to be inspected within a preset time, and perform a fault screening operation based on the collected parameters to determine whether the component to be inspected has a fault. If it is determined that no fault has occurred, perform an environmental adjustment operation to analyze and determine the source of the fault.

[0031] In step S22, the steps of performing the fault screening operation are:

[0032] S221, the operating parameters include voltage variation amplitude and current variation frequency; the correlation detection unit combines the voltage variation amplitude and current variation frequency of the component to be detected with time records to generate a voltage amplitude-time line graph and a current frequency-time line graph;

[0033] S222, equally intercepting the voltage amplitude-time line graph and the current frequency-time line graph, and generating voltage amplitude line segments and current frequency line segments;

[0034] S223. After respectively superimposing and comparing the voltage amplitude line segment and the current frequency line segment with corresponding preset line segments, obtain the overlap percentages of the voltage amplitude line segment and the current frequency line segment, and then add the overlap percentages and divide by two to obtain an overlap mean; the preset line segments are the voltage amplitude-time line graph and the current frequency-time line graph under normal operating conditions;

[0035] S224. Compare the superposition mean value with a superposition preset value, where the superposition preset value is the superposition mean value under normal working conditions; the comparison result includes any one of the following:

[0036] The first type: if the overlap mean value is less than the overlap preset value, the component to be tested may be faulty;

[0037] The second type: If the superposition mean value ≥ the superposition preset value, perform environmental adjustment operations to analyze and determine the source of the fault.

[0038] In step S224, the steps of the environment adjustment operation are:

[0039] Compare the environmental parameters with the corresponding preset environmental parameter ranges, where the preset environmental parameter ranges are the environmental parameter range values under normal working conditions; the comparison results include any one of the following:

[0040] The first type: if the environmental parameters are within the preset environmental parameter range, then the component to be tested is not faulty;

[0041] The second method: If the environmental parameter is outside the preset environmental parameter range, the environmental parameter is subtracted from the maximum value and the minimum value in the corresponding preset environmental parameter range, and then the differences after subtraction are summed and averaged to obtain the environmental adjustment mean, and the environmental processing operation is performed based on the environmental adjustment mean. If the environmental adjustment mean is still generated after the preset time after the environmental processing operation, the environmental adjustment component is marked as a component to be tested, and the component to be tested may be faulty.

[0042] In step S224, the environmental processing operation refers to:

[0043] The positive and negative values of the environment adjustment mean are used to control the environment adjustment elements so that the parameters are adaptively adjusted so that the node device is in the best operating environment. After the environment processing operation is completed, step S224 is repeated.

[0044] The control system further includes a server and an operation and maintenance detection unit, wherein the plurality of single-thread control units and the operation and maintenance detection units are all connected to the server, and a thread storage unit is further provided in the single-thread control unit;

[0045] The server is used to receive and store node device information that may fail screened by the single-threaded control unit;

[0046] The thread storage unit is used to retrieve the relevant data of the thread self-checking unit and the associated detection unit for temporary storage. When the storage capacity reaches a preset amount, it packages it into a data packet to be checked and sends it to the server. The original data corresponding to the data packet to be checked is deleted within a preset time after the data packet to be checked is sent. After the server receives the data packet to be checked, it stores it according to the time of receipt;

[0047] The operation and maintenance detection unit is used to extract data of the data packet to be detected, obtain its mean coordinate set, and perform cumulative normalization processing on it to determine whether overall maintenance is required.

[0048] The steps for determining whether overall maintenance is required are:

[0049] S3. The operation and maintenance detection unit extracts and decompresses the data packets to be inspected within a preset period, and then sums and averages the similar data in the data packets to be inspected to obtain a mean coordinate set. The mean coordinate set is specifically expressed as follows:

[0050] {A1: (Q1, W1, P1), A2: (Q2, W2, P2), ..., An: (Qi, Wi, Pi)};

[0051] Among them: A1, A2, An are the mean coordinate sets, Q, W, P are the same type of data in the data packet to be inspected;

[0052] Where: i and n are both positive integers, and i=n;

[0053] S4. Analyze it using the cumulative normalization formula to obtain the overall operation and maintenance benchmark value Y. The cumulative normalization formula is as follows:

[0054]

[0055]

[0056]

[0057]

[0058] Among them: k1, k2, k3 are all correction coefficients, and k1>k2>k3;

[0059] S5. Compare the overall operation and maintenance benchmark value Y with the preset decay range y. If the overall operation and maintenance benchmark value Y is within the preset decay range y, a maintenance signal is generated, the node device is marked as a component to be replaced, and the information of the component to be replaced is sent to the server; if the overall operation and maintenance benchmark value Y is within the preset decay range y, no maintenance signal is generated and no overall maintenance is required.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

[0061] 1. In the present invention, an electric power equipment operation fault control system and its operation method are configured by setting a one-to-one correspondence between a plurality of node devices and a plurality of single-thread control units, so as to realize the information collection and processing of the single-line operation parameters corresponding to a single or multiple node devices in synchronization, reduce the possibility of system congestion and lag, and automatically control and adjust the operation protection element by retrieving the adjustment signal to realize the self-adjustment of the initial fault and improve the operation and maintenance efficiency. Then, by determining the duration of the self-adjustment, the associated detection unit is controlled to perform a fault screening operation, and then the node device parameter information is arranged through secondary analysis to lock the operation protection element that may have a fault, and the operation parameters and environmental parameters of the operation protection element are collected, and the image normalization method is used for fault screening and the environmental parameters are analyzed and judged. Finally, the fault element that may have a fault is determined. When analyzing and judging the source of the fault, the corresponding parameter data is collected, avoiding the extra consumption caused by continuous collection, reducing the consumption of dynamic detection, and ensuring the stable and efficient operation of the system. Therefore, the present invention not only has a smooth system operation, but also runs stably and efficiently.

[0062] 2. The present invention provides a power equipment operation fault control system and its operation method, further comprising a thread storage unit and an operation and maintenance detection unit. The thread storage unit is used to retrieve relevant data from the thread self-test unit and the associated detection unit for temporary storage. When the storage capacity reaches a preset capacity, the data is packaged into a data packet to be inspected and sent to the server. The original data corresponding to the data packet is deleted within a preset time after the data packet to be inspected is sent. After receiving the data packet to be inspected, the server stores it according to the time of receipt, thereby reducing its own storage pressure. The operation and maintenance detection unit periodically extracts data from the data packet to be inspected to determine whether overall maintenance is required. Regular overall system maintenance is conducive to maintaining efficient and stable operation of the system. Therefore, the system of the present invention operates stably and efficiently.

[0063] 3. In the present invention, a power equipment operation fault management and control system and its operation method are provided with a registration and login unit in the server, and interact with the server via a mobile terminal. When a system fault occurs, the fault information is sent from the server to the mobile terminal, facilitating timely maintenance by maintenance personnel and improving operation and maintenance efficiency. After the maintenance personnel register as registered personnel and perform maintenance, the maintenance situation is recorded, facilitating the later statistics of maintenance data, and promoting the long-term stable operation of the system. Therefore, the present invention not only has high operation and maintenance efficiency, but also relatively stable system operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0069] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] See also Figure 1 — Figure 3 , a power equipment operation fault management and control system, the management and control system includes a plurality of node devices 1 and a plurality of single-threaded management and control units 2;

[0071] The plurality of node devices 1 are connected to the plurality of single-threaded control units 2 in a one-to-one correspondence;

[0072] The node device 1 includes a detection sensing element 11, an operation protection element 12 and an environment adjustment element 13; the single thread control unit 2 includes a thread collection unit 21, a thread self-checking unit 22 and an association detection unit 23;

[0073] The detection sensing element 11 is used to detect the operating parameter information of the node device 1; the operation protection element 12 is used to perform retrieval and self-adjustment; the environmental adjustment element 13 is used to adjust the environmental parameters;

[0074] The thread collection unit 21 is used to collect the operating parameter information of the node device 1 detected by the detection sensing element 11 and send it to the thread self-checking unit 22;

[0075] The thread self-checking unit 22 is used to receive the operating parameter information of the node device 1 sent by the thread collecting unit 21 and control the operation protection element 12 to perform a retrieval and self-adjustment operation, and then send the operating parameter information of the node device 1 that may fail to the association detection unit 23;

[0076] The association detection unit 23 is used to receive the operating parameter information of the node device 1 that may fail sent by the thread self-check unit 22, perform fault screening, and then control the environment adjustment element 13 to perform environment adjustment operations to analyze and determine the source of the fault.

[0077] An operating method of a power equipment operation fault management and control system, the operating method comprises the following steps:

[0078] S1. The detection sensing element 11 detects operating parameter information of the node device 1, collects the information through the thread collection unit 21, and sends the information to the thread self-checking unit 22. The thread self-checking unit 22 receives the information and performs a double normalization process on the information to determine whether a search adjustment signal is generated. If a search adjustment signal is generated, the operation protection element 12 is controlled to perform a search self-adjustment operation and determine whether the node device 1 may have a fault. If it is determined that a fault may have occurred, the operating parameter information of the node device 1 is sent to the association detection unit 23 to perform step S2.

[0079] S2. After receiving the information, the associated detection unit 23 marks the operating protection element 12 that may have a fault as the component to be detected through secondary analysis and arrangement, and then collects the operating parameters and environmental parameters of the component to be detected to perform fault screening and determine whether the component to be detected has a fault. If it is determined that there is no fault, the image normalization method is used to perform fault screening, and the associated environmental parameters are used to control the environmental adjustment element 13 to perform environmental adjustment operations to analyze and determine the source of the fault.

[0080] In step S1, the steps of double normalization processing are:

[0081] S11. After receiving the operating parameter information of the node device 1, the thread self-check unit 22 compares the operating parameter information of the node device 1 with the corresponding preset threshold ranges, where the preset threshold ranges are the operating parameter range values of the node device 1 under normal operating conditions. The comparison results include any one of the following:

[0082] The first type: if the operating parameter information of the node device 1 is within the preset threshold range, then the node device 1 is not faulty;

[0083] The second method: if the operating parameter information of the node device 1 is outside the preset threshold range, proceed to step S12;

[0084] S12. If the operating parameter information of node device 1 is less than the minimum value of the preset threshold range, the minimum value of the preset threshold range is subtracted from the corresponding operating parameter information of node device 1, and then the subtraction difference is multiplied by the corresponding weight parameter 1, and finally the products are summed and averaged to obtain the limit minimum mean;

[0085] If the operating parameter information of node device 1 is greater than the maximum value of the preset threshold range, the maximum value of the preset threshold range is subtracted from the corresponding operating parameter information of node device 1, and then the difference after subtraction is multiplied by the corresponding weight parameter 2, and then the products are summed and averaged to obtain the maximum mean value of the limit;

[0086] Finally, the limit minimum mean and the limit maximum mean are compared with the preset limit threshold range respectively. If the limit minimum mean and the limit maximum mean are both outside the preset limit range, a retrieval adjustment signal is generated.

[0087] In step S1, the steps of performing the retrieval self-adjustment operation and determining whether the node device may have a fault are as follows:

[0088] S13, after the retrieval adjustment signal is generated, the retrieval self-adjustment operation is performed to control the operation protection element 12 to perform automatic adjustment;

[0089] S14: After the automatic adjustment is completed, the duration of the adjustment of the operating protection element 12 is obtained, and the duration is compared with a preset duration, where the preset duration is the duration expected to be taken by the operating protection element 12 to complete the automatic adjustment. The comparison result includes any one of the following:

[0090] The first type: if the duration is less than the preset duration, the operating parameter information of the node device 1 is not sent to the association detection unit 23;

[0091] The second type: if the duration is greater than or equal to the preset duration, the node device 1 may fail, and the operating parameter information of the node device 1 is sent to the association detection unit 23 .

[0092] In step S2, the steps of performing fault screening are:

[0093] S21, after receiving the operating parameter information of the node device 1, the association detection unit 23 arranges the data therein from largest to smallest, obtains the operating protection element 12 corresponding to the largest data, and marks it as the element to be detected;

[0094] S22. Collect the operating parameters and environmental parameters of the component to be inspected within a preset time, and perform a fault screening operation based on the collected parameters to determine whether the component to be inspected has a fault. If it is determined that no fault has occurred, perform an environmental adjustment operation to analyze and determine the source of the fault.

[0095] In step S22, the steps of performing the fault screening operation are:

[0096] S221, the operating parameters include voltage variation amplitude and current variation frequency; the correlation detection unit 23 combines the voltage variation amplitude and current variation frequency of the component to be detected with time records to generate a voltage amplitude-time line graph and a current frequency-time line graph;

[0097] S222, equally intercepting the voltage amplitude-time line graph and the current frequency-time line graph, and generating voltage amplitude line segments and current frequency line segments;

[0098] S223. After respectively superimposing and comparing the voltage amplitude line segment and the current frequency line segment with corresponding preset line segments, obtain the overlap percentages of the voltage amplitude line segment and the current frequency line segment, and then add the overlap percentages and divide by two to obtain an overlap mean; the preset line segments are the voltage amplitude-time line graph and the current frequency-time line graph under normal operating conditions;

[0099] S224. Compare the superposition mean value with a superposition preset value, where the superposition preset value is the superposition mean value under normal working conditions; the comparison result includes any one of the following:

[0100] The first type: if the overlap mean value is less than the overlap preset value, the component to be tested may be faulty;

[0101] The second type: If the superposition mean value ≥ the superposition preset value, perform environmental adjustment operations to analyze and determine the source of the fault.

[0102] In step S224, the steps of the environment adjustment operation are:

[0103] Compare the environmental parameters with the corresponding preset environmental parameter ranges, where the preset environmental parameter ranges are the environmental parameter range values under normal working conditions; the comparison results include any one of the following:

[0104] The first type: if the environmental parameters are within the preset environmental parameter range, then the component to be tested is not faulty;

[0105] The second type: If the environmental parameter is outside the preset environmental parameter range, the environmental parameter is subtracted from the maximum value and the minimum value in the corresponding preset environmental parameter range, and then the differences after subtraction are summed and averaged to obtain the environmental adjustment mean, and the environmental processing operation is performed based on the environmental adjustment mean. If the environmental adjustment mean is still generated after the preset time after the environmental processing operation, the environmental adjustment element 13 is marked as a component to be tested, and the component to be tested may be faulty.

[0106] In step S224, the environmental processing operation refers to:

[0107] The positive and negative values of the environment adjustment mean are used to control the environment adjustment element 13 so that it can adaptively adjust the parameters so that the node device 1 is in the best operating environment. After the environment processing operation is completed, step S224 is repeated.

[0108] The control system further includes a server 3 and an operation and maintenance detection unit 4. The plurality of single-thread control units 2 and the operation and maintenance detection unit 4 are connected to the server 3. The single-thread control unit 2 is further provided with a thread storage unit 24.

[0109] The server 3 is used to receive and store information of node devices 1 that may fail, which is screened by the single-threaded control unit 2;

[0110] The thread storage unit 24 is used to retrieve the relevant data of the thread self-checking unit 22 and the associated detection unit 23 for temporary storage. When the storage capacity reaches a preset amount, it packages the data into a data packet to be checked and sends it to the server 3. The original data corresponding to the data packet to be checked is deleted within a preset time after the data packet to be checked is sent. After receiving the data packet to be checked, the server 3 stores it according to the time of receipt.

[0111] The operation and maintenance detection unit 4 is used to extract data of the data packet to be detected, obtain its mean coordinate set, and perform cumulative normalization processing on it to determine whether overall maintenance is required.

[0112] The steps for determining whether overall maintenance is required are:

[0113] S3, the operation and maintenance detection unit 4 extracts the data packets to be inspected within a preset period and decompresses them, and then sums and averages the similar data in the data packets to be inspected to obtain a mean coordinate set, which is specifically expressed as follows:

[0114] {A1: (Q1, W1, P1), A2: (Q2, W2, P2), ..., An: (Qi, Wi, Pi)};

[0115] Among them: A1, A2, An are the mean coordinate sets, Q, W, P are the same type of data in the data packet to be inspected;

[0116] Where: i and n are both positive integers, and i=n;

[0117] S4. Analyze it using the cumulative normalization formula to obtain the overall operation and maintenance benchmark value Y. The cumulative normalization formula is as follows:

[0118]

[0119]

[0120]

[0121]

[0122] Among them: k1, k2, k3 are all correction coefficients, and k1>k2>k3;

[0123] S5. Compare the overall operation and maintenance benchmark value Y with the preset decay range y. If the overall operation and maintenance benchmark value Y is within the preset decay range y, a maintenance signal is generated, the node device 1 is marked as a component to be replaced, and the information of the component to be replaced is sent to the server 3; if the overall operation and maintenance benchmark value Y is within the preset decay range y, no maintenance signal is generated and no overall maintenance is required.

[0124] The principle of the present invention is described as follows:

[0125] The environmental processing operation is specifically to control the environmental adjustment element 13 to adaptively adjust the parameters through the positive and negative environmental adjustment mean values so that the node device 1 is in the best operating environment. Taking the environmental adjustment element 13 as a temperature adjustment device as an example, if the best operating environment is 0°, when the environmental adjustment mean value is -5, the environmental adjustment element 13 is controlled to increase the temperature inside the node device 1 to ensure that the temperature inside is in the best operating temperature environment. Similarly, when the environmental adjustment mean value is +5, the environmental adjustment element 13 is controlled to lower the temperature inside the node device 1.

[0132] The thread self-checking unit 22 is used to receive the operating parameter information of the node device 1 sent by the thread collecting unit 21 and control the operation protection element 12 to perform a retrieval and self-adjustment operation, and then send the operating parameter information of the node device 1 that may fail to the association detection unit 23;

[0133] The association detection unit 23 is used to receive the operating parameter information of the node device 1 that may have a fault sent by the thread self-checking unit 22, and perform fault screening, and then control the environment adjustment element 13 to perform an environment adjustment operation to analyze and determine the source of the fault;

[0134] The operation method steps of the control system are as follows:

[0136] Furthermore, the steps of the double normalization process are as follows:

[0137] S11. After receiving the operating parameter information of the node device 1, the thread self-check unit 22 compares the operating parameter information of the node device 1 with the corresponding preset threshold ranges, where the preset threshold ranges are the operating parameter range values of the node device 1 under normal operating conditions.
