Description

Technical Field

[0001] This invention relates to the field of intelligent control technology, specifically to a fan control system and a system manager. Background Technology

[0002] Fans, as common ventilation and heat dissipation devices, are widely used in homes, industries, and vehicles. Existing fan controls mostly adopt fixed speeds, timers, or simple temperature trigger modes, without analyzing the dynamic changes in fan operating parameters. This easily leads to problems such as ignoring energy consumption and equipment lifespan in pursuit of wind speed and heat dissipation effect, mismatch between wind speed adjustment and environmental requirements, and the inability to provide real-time warnings for operational abnormalities. As a result, the overall control accuracy is low, energy consumption is high, and equipment monitoring is lax.

[0003] Existing publicly available technologies involve fan speed control, which uses a temperature sensor to collect ambient temperature for speed adjustment. However, these technologies do not analyze deviations in operating parameters or consistency of operating trends, thus failing to achieve intelligent management throughout the entire fan lifecycle. Therefore, this invention proposes a fan control system and a system manager. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fan control system and system manager, which solves the problems of existing fan controls failing to analyze changes in operating parameters, having low control precision, and lacking strict supervision.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fan control system, comprising:

[0006] The operation parameter acquisition end is used to acquire the fan operation data reported by the fan and transmit the acquired operation data of different fan units to the operation parameter analysis end.

[0007] The operating parameter analysis terminal marks the operating data of different fan units according to the specific operating path and status of the fan, and performs unified analysis and processing on the marked operating data to determine whether the corresponding fan unit is operating normally.

[0008] The specific method for unified analysis and processing of the operating parameter analysis terminal is as follows:

[0009] The operating data of different fan units are labeled as YD i , where i represents different fan units, and i = 1, 2, ..., n;

[0010] Several sets of running data YD i Perform averaging to confirm the operating average YZ, and then obtain the deviation parameter PC of the current fan unit. i The deviation difference PC iThe value is compared with the preset parameter Y1, where Y1 is the preset value, and its specific value is determined by the operator based on experience. When PC i When the value is greater than Y1, it indicates that the deviation value is too large. The corresponding fan unit is marked as abnormal operation and the abnormal operation analysis terminal is executed. Conversely, when the value is less than Y1, it indicates that the deviation value is normal and the normal operation analysis terminal is executed directly.

[0011] The normal operation analysis unit includes a preliminary marking unit and a comprehensive analysis unit. The preliminary marking unit confirms the total operating data of each normal fan, analyzes whether the corresponding total operating data meets the standards, and marks the corresponding fan based on the analysis results.

[0012] The specific method for analyzing the preliminary marking unit is as follows:

[0013] Confirm the total operating data of the fan and mark it as SJ. t Where t represents different fans, SJ t With preset parameter Y t Comparison was performed, where Y t The preset operating values ​​are determined in advance by the operator. When SJt≥Yt, this fan is marked as a standard fan; otherwise, it is marked as a deviation fan.

[0014] The specific method of analysis and comparison unit is as follows: based on the acquired running image, the corresponding model surface is identified from the complete running model, and the size parameters of the running image and the model surface are compared. When the comparison results are consistent, a trend analysis signal is generated and directly transmitted to the trend analysis unit. When the comparison results are inconsistent, a fan unit abnormal signal is generated and directly transmitted to the display end.

[0015] The comprehensive analysis unit confirms the operating data of each fan unit for different fans, performs comprehensive processing, determines the positive or negative value of the comprehensive processing value, and then re-marks the marked fans.

[0016] The specific method for marking the comprehensive analysis unit is as follows:

[0017] The operating data of different fans and different fan units are marked as SS. t-q Where t represents different fans, and q represents different fan units, where q = 1, 2, ..., m, using FL t-w =SS t-（q+1） -SS t-q We obtain w adjacent differences FL t-w Where w=m-1, and then several adjacent differences FL t-w Perform summation to obtain the merged parameter HB. t ;

[0018] If HB t If the value is greater than 0, and the fan is a standard deviation fan, then mark the standard deviation fan as a standard deviation rising fan;

[0019] If HB t If the value is less than 0, and this fan is a standard fan, then the standard fan will be marked as a standard descending fan;

[0020] In other cases, no processing is performed; the original markings remain unchanged, and the processed fans are transmitted to the display terminal for display.

[0021] The abnormal operation analysis terminal includes an image acquisition unit, an analysis and comparison unit, a model library, and a trend analysis unit;

[0022] The image acquisition unit acquires the operating images of the corresponding fan unit through the on-site image acquisition device of the corresponding fan unit, and transmits the acquired operating images to the analysis and comparison unit.

[0023] The analysis and comparison unit selects a complete operating model of the corresponding fan unit from the model library. The complete operating model is a preset model. The unit analyzes and compares the acquired operating image with the complete operating model. Based on the comparison results, it determines whether the corresponding fan unit is operating normally.

[0024] The trend analysis unit performs trend analysis on different running images. From the complete running model, it confirms the trend value of the corresponding model surface and then analyzes whether the two sets of trend values ​​are consistent. If they are consistent, there is no problem; if they are inconsistent, it means that the corresponding fan unit is abnormal.

[0025] The trend analysis unit performs trend analysis in the following specific way:

[0026] From the running image, confirm whether the corresponding fan unit has any protruding vertices:

[0027] If a vertex exists, connect the confirmed vertex to the center point of the fan unit and mark the confirmed connection as the running line. Then, select the vertex and the center point of the fan unit in the complete running model and connect them to confirm the model line. Place the running line and the model line in a two-dimensional coordinate system. Use the point coordinates inside the two-dimensional coordinate system to confirm the linear equations of the two sets of line segments respectively. Mark the internal trend value of the linear equation of the running line as K1 and the internal trend value of the linear equation of the model line as K2. When K1=K2, no processing is performed. Otherwise, an abnormal signal of the fan unit is generated and directly transmitted to the display terminal.

[0028] If no vertex exists, select the two endpoints of the fan unit to confirm the running line belonging to the fan unit. At the same time, select the two endpoints of the complete running model to confirm the model line belonging to this running model. Combine the running line and the model line with the two-dimensional coordinate system to confirm the corresponding trend value K. Then compare whether the trend value K is consistent. If consistent, no processing is performed. Otherwise, generate a fan unit abnormal signal and transmit it directly to the display terminal.

[0029] A system manager for performing:

[0030] Full-cycle management including operation parameter acquisition, operation parameter analysis, normal operation marking, abnormal operation judgment, trend analysis, signal output and status display.

[0031] Beneficial effects

[0032] This invention provides a fan control system and a system manager. Compared with the prior art, it has the following advantages:

[0033] This invention analyzes corresponding operating values ​​to determine if there are any operational abnormalities in the fan units of a given fan. If so, an operational abnormality analysis is performed, prioritizing the analysis of whether the operating parameters of the fan units are consistent. Subsequently, the angles of the fan units are analyzed to determine if they are consistent. If both are normal, it indicates that there are no operational problems. If abnormalities are found, timely handling and warnings are issued to improve the overall control effect of the fan units and avoid situations where energy consumption and lifespan are ignored in order to improve operating performance, thus ensuring control quality to a certain extent. Subsequently, the overall operating status of normal fan units is analyzed. During the analysis, the fluctuation trend of each fan unit is taken into account and marked in a timely manner. At the same time, the operator makes corresponding control adjustment plans in a timely manner to improve accuracy and make subsequent control adjustments more rational, avoiding control adjustment abnormalities.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This application provides a fan control system, including an operating parameter acquisition terminal, an operating parameter analysis terminal, a normal operation analysis terminal, an abnormal operation analysis terminal, and a display terminal, wherein the operating parameter acquisition terminal is electrically connected to the input node of the operating parameter analysis terminal, and the operating parameter analysis terminal is electrically connected to the input nodes of the normal operation analysis terminal and the abnormal operation analysis terminal, respectively.

[0037] The normal operation analysis terminal includes a preliminary marking unit and a comprehensive analysis unit, and the abnormal operation analysis terminal includes an operation image acquisition unit, an analysis and comparison unit, a model library, and a trend analysis unit. The operation image acquisition unit and the model library are electrically connected to the input node of the analysis and comparison unit, and the analysis and comparison unit is electrically connected to the input node of the trend analysis unit.

[0038] The operating parameter acquisition terminal is used to acquire the fan operating data reported by the fan and transmit the acquired operating data of different fan units to the operating parameter analysis terminal.

[0039] The operating parameter analysis terminal marks the operating data of different fan units according to the specific operating path and status of the fans, and performs unified analysis and processing on the marked operating data to determine whether the corresponding fan unit is operating normally. Specifically, the unified analysis and processing is performed by marking the operating data of different fan units as YD. i Where i represents different fan units, and i = 1, 2, ..., n; several sets of operating data YD i Perform averaging to confirm the operating average YZ, and then obtain the deviation parameter PC of the current fan unit. i The deviation difference PC i The value is compared with the preset parameter Y1, where Y1 is the preset value, and its specific value is determined by the operator based on experience. When PC i When the value is greater than Y1, it indicates that the deviation value is too large. The corresponding fan unit is marked as abnormal operation and the abnormal operation analysis terminal is executed. Conversely, when the value is less than Y1, it indicates that the deviation value is normal and the normal operation analysis terminal is executed directly.

[0040] The image acquisition unit inside the abnormal operation analysis terminal acquires the operation image of the corresponding fan unit through the on-site image acquisition device of the corresponding fan unit, and transmits the acquired operation image to the analysis and comparison unit.

[0041] The analysis and comparison unit selects a complete operating model of the corresponding fan unit from the model library. The complete operating model is a preset model, and its specific parameters are determined in advance by the operator. The acquired operating image is analyzed and compared with the complete operating model. Based on the comparison results, it is determined whether the corresponding fan unit is operating normally. The specific method of analysis and comparison is as follows: based on the acquired operating image, the corresponding model surface is identified from the complete operating model. The size parameters of the operating image and the model surface are compared. When the comparison results are consistent, a trend analysis signal is generated and directly transmitted to the trend analysis unit. When the comparison results are inconsistent, a fan unit abnormal signal is generated and directly transmitted to the display end.

[0042] The trend analysis unit performs trend analysis on different running images based on trend analysis signals. It then confirms the trend value of the corresponding model surface within the complete running model and analyzes whether the two sets of trend values ​​are consistent. If they are consistent, there is no problem; if they are inconsistent, it indicates an abnormality in the corresponding fan unit. The specific method for trend analysis is as follows: From the running image, it confirms whether the corresponding fan unit has a protruding vertex. If a vertex exists, it connects the confirmed vertex to the center point of the fan unit, marking the connection as the running line. Then, from the complete running model, it selects the vertex and the center point of the model fan unit, connects them, and confirms the model line. The running line and the model line are placed in a two-dimensional coordinate system. The analysis is then performed within the two-dimensional coordinate system. The coordinates of the points are used to confirm the linear equations of the two sets of line segments. The internal trend value of the linear equation of the running line is marked as K1, and the internal trend value of the linear equation of the model line is marked as K2. When K1=K2, no processing is performed. Otherwise, a fan unit abnormal signal is generated and directly transmitted to the display. If there are no vertices, the two endpoints of the fan unit are selected to confirm the running line belonging to the fan unit. At the same time, the two endpoints of the complete running model are selected to confirm the model line belonging to this running model. The running line and the model line are combined with the two-dimensional coordinate system to confirm the corresponding trend value K. The trend values ​​K are then compared to see if they are consistent. If they are consistent, no processing is performed. Otherwise, a fan unit abnormal signal is generated and directly transmitted to the display.

[0043] The preliminary marking unit inside the normal operation analysis terminal confirms the total operating data of each normal fan. A fan unit contains several fan units; if no fan unit has a problem, it indicates that the fan is in normal operation. If a problem exists, it is analyzed and processed by the abnormal operation analysis terminal to determine if the corresponding total operating data meets the standards. Based on the analysis results, the corresponding fan is initially marked. Specifically, the analysis method involves confirming the total operating data of the fan and marking it as SJ. t Where t represents different fans, SJ t With preset parameter Y t Comparison was performed, where Yt The preset operating values ​​are determined in advance by the operator. When SJ t ≥Y t When the condition is met, mark the fan as a standard fan; otherwise, mark it as a tolerance fan.

[0044] The comprehensive analysis unit confirms the operating data of each fan unit for different fans, performs comprehensive processing, determines the positive or negative value of the comprehensive processing value, and then re-marks the marked fans. Specifically, the marking process involves labeling the operating data of different fans and fan units as SS. t-q Where t represents different fans, and q represents different fan units, where q = 1, 2, ..., m, using FL t-w =SS t-（q+1） -SS t-q We obtain w adjacent differences FL t-w Where w=m-1, and then several adjacent differences FL t-w Perform summation to obtain the merged parameter HB. t If HB t If the value is greater than 0, and the fan is a standard deviation fan, then mark the standard deviation fan as a standard deviation rising fan; if HB t If the value is less than 0, and the fan is a standard fan, then the standard fan will be marked as a standard descending fan; otherwise, no processing will be performed, the original marking will remain unchanged, and the processed fans will be transmitted to the display terminal for display.

[0045] Example 2

[0046] A fan control method includes the following steps: Step 1: Based on the fan operation data, determine whether different fan units of the corresponding fan are normal. If not, analyze through an abnormal operation analysis terminal; if normal, analyze through a normal operation analysis terminal. Step 2: The abnormal operation analysis terminal first confirms the model surface corresponding to the complete operation model based on the corresponding operation image, compares the parameters of the operation image and the model surface, and analyzes whether the dimensions are consistent. If they are inconsistent, it indicates a fan abnormality. If they are consistent, perform angle analysis. If the angle analysis results are inconsistent, it also indicates a fan abnormality. Step 3: Analyze the operating status of normal fans, and mark different fans according to the analysis results. At the same time, analyze the interval operation status of different fans and different fan units to determine whether it is an upward or downward trend, and mark and display it again for external personnel to respond in a timely manner and make corresponding control and adjustment plans.
