Detailed Implementation

[0013] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0014] In the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0015] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0016] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0017] Please see Figure 1 , Figure 1 This is a flowchart illustrating the industrial equipment behavior prediction method based on multi-source data fusion provided in this application embodiment. In this embodiment, the execution subject of the industrial equipment behavior prediction method is a terminal device. It is understood that the types of terminal devices include, but are not limited to, mobile phones, tablets, laptops, Ultra-Mobile Personal Computers (UMPCs), netbooks, Personal Digital Assistants (PDAs), etc. This application embodiment does not impose any restrictions on the specific type of terminal device.

[0018] Please see Figure 1 The industrial equipment behavior prediction method provided in this application includes, but is not limited to, the following steps: In S100, in response to the start-up command, the system continuously acquires the feature parameter set information and real-time monitoring video stream information of the device under test based on preset sensors.

[0019] Specifically, the terminal device can first respond to the start-up command and continuously acquire the characteristic parameter set information and real-time monitoring video stream information of the device under test based on preset sensors. The start-up command describes the start-up of the device under test, which can be an oil pump, including a heat exchanger. The characteristic parameter set information includes real-time pressure parameter information and real-time temperature parameter information. The real-time pressure parameter information describes the real-time pressure at the inlet and outlet of the heat exchanger, and the real-time temperature parameter information describes the real-time temperature of the heat exchanger.

[0020] Without loss of generality, real-time pressure parameter information can be obtained through a preset pressure sensor; real-time temperature parameter information can be obtained through a preset temperature sensor; and real-time monitoring video stream information can be obtained through a preset image sensor.

[0021] It should be noted that when a heat exchanger is blocked, the narrowed flow channels increase fluid resistance, leading to a significant and abnormal increase in pressure at the inlet and outlet of the heat exchanger. In severely blocked areas, "hot spots" will appear on the surface of the tube bundles or plates, resulting in abnormal temperature regions.

[0022] In S200, the first evaluation result information is generated based on the feature parameter set information and the preset prediction anomaly parameter set information.

[0023] Specifically, after the terminal device acquires the feature parameter set information and the real-time monitoring video stream information, the terminal device can accurately generate the first evaluation result information based on the feature parameter set information and the preset predicted anomaly parameter set information. The first evaluation result information includes the first normal operation information or the first predicted fault operation information. The first normal operation information is used to describe that the device under test is still in normal operation in the future. The first predicted fault operation information is used to describe that the device under test is about to be in fault operation.

[0024] Without loss of generality, the predicted anomaly parameter set information includes the predicted anomaly pressure average information and the predicted anomaly temperature average information. The predicted anomaly pressure average information is used to describe the predicted average pressure value when a blockage anomaly is about to occur, and the predicted anomaly temperature average information is used to describe the predicted average temperature value when a blockage anomaly is about to occur.

[0025] In some possible implementations, to determine accurate information about the predicted anomaly parameter set, please refer to [link / reference needed]. Figure 2 Before step S201, the method also includes, but is not limited to, the following steps: In S201, based on a preset sampling time period, multiple abnormal state information of the device under test and the abnormal time information corresponding to each abnormal state information are obtained.

[0026] Specifically, the terminal device can acquire multiple abnormal status information of the device under test and the abnormal time information corresponding to each abnormal status information based on a preset sampling time period. The sampling period can be one month or one week prior; the abnormal status information describes the blockage abnormality of the device under test; and the abnormal time information describes the moment when the blockage abnormality of the device under test was determined to have occurred within the sampling period.

[0027] In S202, based on the abnormal time information, according to the order of occurrence time, it is determined whether the time interval between any two abnormal state information is less than the preset association time threshold.

[0028] Specifically, after the terminal device obtains the abnormal status information and the abnormal time information, the terminal device can, based on the abnormal time information, sequentially determine whether the time interval between any two abnormal status information is less than a preset association time threshold in the order of their occurrence. The association time threshold can be customized, such as 5 minutes or 10 minutes.

[0029] In S203, if the time interval between two abnormal status information is less than the associated time threshold, the abnormal time information that occurred later is deleted, and the abnormal time information that occurred earlier is determined as the target time information.

[0030] Specifically, if the time interval between two abnormal status information is less than the associated time threshold, the terminal device can delete the abnormal time information that occurred later, retain the abnormal time information that occurred earlier, and determine the abnormal time information that occurred earlier as the target time information, thereby eliminating redundant abnormal status information that continues to be generated due to failure to stop operation in time when a blockage occurs.

[0031] In S204, for each target time information, the backtracking time information is determined according to the preset backtracking time interval value.

[0032] Specifically, after the terminal device determines the target time information, the terminal device can perform this processing for each target time information. According to the preset backtracking time interval value, the backtracking time information is determined. The occurrence time of the backtracking time information is earlier than the occurrence time of the target time information. The time interval between the backtracking time information and the target time information is the backtracking time interval value. The backtracking time interval value can be customized, such as 1 minute or 3 minutes.

[0033] In S205, based on the retrospective time information, the predicted abnormal pressure value information and the predicted abnormal temperature parameter value information are determined.

[0034] Specifically, after the terminal device determines the retrospective time information, it can determine the pressure value of the device under test in the retrospective time information as the predicted abnormal pressure value information, and determine the temperature value of the device under test in the retrospective time information as the predicted abnormal temperature parameter value information.

[0035] In S206, the average value of predicted abnormal pressure is generated based on multiple predicted abnormal pressure values.

[0036] Specifically, after the terminal device determines the predicted abnormal pressure value information and the predicted abnormal temperature parameter value information, the terminal device can generate the predicted abnormal pressure average value information based on the average of the sum of multiple predicted abnormal pressure value information.

[0037] In S207, the mean value information of the predicted abnormal temperature parameters is generated based on multiple predicted abnormal temperature parameter values.

[0038] Specifically, after the terminal device generates the predicted abnormal pressure average information, the terminal device can generate the predicted abnormal temperature parameter average information based on the average of the sum of multiple predicted abnormal temperature parameter values.

[0039] In some possible implementations, to generate the first evaluation result information, please refer to [link / reference]. Figure 3 Step S200 includes, but is not limited to, the following steps: In S210, pressure difference information is generated based on real-time pressure parameter information and predicted average abnormal pressure information.

[0040] Specifically, after the terminal device acquires the feature parameter set information and the real-time monitoring video stream information, the terminal device can generate pressure difference information by subtracting the predicted average abnormal pressure information from the real-time pressure parameter information.

[0041] In S220, temperature difference information is generated based on real-time temperature parameter information and predicted abnormal temperature parameter values.

[0042] Specifically, after the terminal device generates pressure difference information, it can generate temperature difference information by subtracting the predicted abnormal temperature parameter value from the real-time temperature parameter information.

[0043] In S230, it is determined whether the pressure difference information is less than the preset pressure threshold information and whether the temperature difference information is less than the preset temperature threshold information.

[0044] Specifically, after the terminal device generates temperature difference information, it can determine whether the pressure difference information is less than the preset pressure threshold information, and whether the temperature difference information is less than the preset temperature threshold information. Both the pressure threshold information and the temperature threshold information can be customized by maintenance personnel according to the specific situation of the device to be tested.

[0045] In S240, if the pressure difference information is less than the pressure threshold information and the temperature difference information is less than the temperature threshold information, then the first normal operation information is generated; otherwise, the first predicted fault operation information is generated.

[0046] Specifically, if the pressure difference information is less than the pressure threshold information and the temperature difference information is less than the temperature threshold information, the terminal device can generate the first normal operation information; otherwise, the terminal device can generate the first predicted fault operation information.

[0047] In S300, a second evaluation result is generated based on a preset target detection algorithm and real-time monitoring video stream information.

[0048] Specifically, after the terminal device generates the first evaluation result information, it can accurately generate the second evaluation result information based on the preset target detection algorithm and the real-time monitoring video stream information, thereby realizing the re-evaluation of the device under test. The second evaluation result information includes the second normal operation information or the second fault operation information. The second normal operation information is used to describe that the device under test is in a normal operation state after re-evaluation, and the second fault operation information is used to describe that the device under test is in a fault operation state after re-evaluation, that is, the device under test is in a blocked abnormality. The real-time monitoring video stream information includes multiple real-time monitoring image information.

[0049] In some possible implementations, for accurate generation of second evaluation result information, please refer to [link / reference]. Figure 4 Step S300 includes, but is not limited to, the following steps: In S310, for each real-time monitoring image, the contour information to be detected is determined based on a preset edge contour extraction algorithm.

[0050] Specifically, the terminal device can perform this processing on each real-time monitoring image information. Based on a preset edge contour extraction algorithm, it determines the contour information to be detected corresponding to each real-time monitoring image information. The edge contour extraction algorithm can be the Canny algorithm or the Sobel algorithm.

[0051] In S320, based on a preset target detection algorithm, the object type information corresponding to the contour information to be detected is determined according to the contour information to be detected.

[0052] Specifically, after the terminal device determines the contour information to be detected, it can determine the object type information corresponding to the contour information based on the preset target detection algorithm. The object type information describes the type corresponding to the contour information to be detected. The object type information includes device type information or other type information. The device type information describes the device itself, which is the device to be detected, i.e., the shape contour of the device itself. Other type information can be an oily area, which is the oily deposit area accumulated on the outer shell due to heat exchanger blockage.

[0053] In S330, if the object type information is device type information, then second normal operation information is generated; otherwise, second fault operation information is generated.

[0054] Specifically, if the object type information is device type information, it indicates that the outline in the real-time monitoring image information is the original shape outline of the device to be detected, so the terminal device can generate the second normal operation information; otherwise, it indicates that in addition to the original shape outline of the device to be detected, there are other dirt outlines in the outline of the real-time monitoring image information, so the terminal device can generate the second fault operation information.

[0055] In S400, anomaly prediction information is generated based on the first evaluation result information and the second evaluation result information.

[0056] Specifically, after the terminal device generates the second evaluation result information, it can comprehensively generate anomaly prediction information based on the first and second evaluation result information, thereby predicting the blockage anomaly of the heat exchanger in advance and facilitating the early implementation of corresponding measures. The anomaly prediction information includes anomaly height occurrence information or anomaly moderate occurrence information. Anomaly height occurrence information is used to describe the equipment under test with a very high probability of blockage anomaly, while anomaly moderate occurrence information is used to describe the equipment under test with a relatively high probability of blockage anomaly. The anomaly occurrence rate of anomaly moderate occurrence information is lower than that of anomaly height occurrence information.

[0057] In some possible implementations, for accurate generation of anomaly prediction information, please refer to [link / reference]. Figure 5 Step S400 includes, but is not limited to, the following steps: In S410, if the first evaluation result information is the first predicted fault operation information and the second evaluation result information is the second fault operation information, then abnormal height occurrence information is generated.

[0058] Specifically, if the first assessment result information is the first predicted fault operation information and the second assessment result information is the second fault operation information, then the terminal device can accurately generate abnormal height occurrence information.

[0059] In S420, if the first evaluation result information is the first predicted fault operation information, or the second evaluation result information is the second fault operation information, then the abnormality moderate occurrence information is generated.

[0060] Specifically, if the first assessment result information is the first predicted fault operation information, or the second assessment result information is the second fault operation information, then the terminal device can accurately generate the abnormality moderate occurrence information.

[0061] In one possible implementation, the terminal device can also incorporate a graph neural network (GNN) and a Transformer for state prediction to further assist in predicting the timing of heat exchanger blockage.

[0062] The implementation principle of the industrial equipment behavior prediction method based on multi-source data fusion in this application embodiment is as follows: The terminal device can first respond to the start-up command, continuously acquire the feature parameter set information and real-time monitoring video stream information of the device to be detected based on the preset sensors, and then quickly generate the first evaluation result information based on the feature parameter set information and the preset prediction anomaly parameter set information. Then, based on the preset target detection algorithm and the real-time monitoring video stream information, the second evaluation result information is efficiently generated. Finally, based on the first evaluation result information and the second evaluation result information, the anomaly prediction information is accurately generated, thereby realizing the early prediction of the blockage anomaly of the oil pump and greatly improving reliability.
