[0002] As modern chemical production places higher and higher demands on efficiency and automation, the application of water pumps must not only meet the function of conveying liquids, but also have the characteristics of high efficiency and energy saving, reduce energy consumption, and reduce production costs. For example, by adjusting the working state of the water pump, the pressure and flow in the production process can be optimized and controlled to ensure the continuity and stability of the process. Modern water pumps are usually connected to automated control systems, and precise adjustment and monitoring are achieved through intelligent sensors and controllers to support the automation and digital transformation of chemical plants.

[0003] The wireless transmission and remote monitoring system of water pump operating parameters in existing chemical production has become an important part of digital and intelligent factories. Various sensors installed on the water pump collect the operating parameters and environmental data of the water pump in real time, and use wireless communication technology (such as LoRa, NB-IoT, etc.) to transmit the collected data to the central control system or cloud platform, and then use the remote server or cloud platform to store, analyze and visualize the data, and realize remote control of the water pump. Finally, users can view real-time data through PC or mobile devices, adjust parameters or remotely control, thereby effectively improving the accuracy and automation level of the chemical production process, and providing chemical companies with convenient and efficient management solutions.

[0004] For example, the cloud computing-based water pump management system announced in the invention patent with announcement number: CN106194692B includes: a field control system, a cloud computing control center and a data acquisition center; the field control system is used to set the normal operating parameters of the water pump and manage and control the operating mode of the water pump according to the normal operating parameters of the water pump, and transmit the normal operating parameters of the water pump to the cloud computing control center; the data acquisition center is used to collect the actual operating parameters of the water pump and transmit them to the cloud computing control center; the cloud computing control center is used to adjust the management and control mode of the field control system according to the actual operating parameters and normal operating parameters of the water pump.

[0005] For example, the invention patent with announcement number CN106050637B announces an online monitoring method for the operating status of a large variable speed water pump, including: recording the operating parameters of the water pump status monitoring; determining the numerical functions of the boundaries of the normal operating area of ​​the water pump according to the designed flow-head curve of the water pump; collecting the operating data of the normal state of the newly commissioned water pump, and fitting the flow-head performance curve of the water pump at a certain specified speed after correction; judging whether the water pump is working in the normal operating area according to the operating parameters of the water pump under the monitoring state. If not, an alarm prompt of abnormal operating status is given; according to the operating parameters of the water pump under the monitoring state, the water pump is corrected to a certain specified speed compared with the normal state curve. If the deviation from the normal state curve exceeds a certain degree, an alarm prompt of abnormal operating status of the water pump is given.

The water pump operation evaluation index is used to evaluate the operating status of the water pump. The water pump data includes the water pump operation evaluation index and operating parameters. An operating parameter transmission evaluation module is used to evaluate the effect of wireless transmission of water pump data after executing wireless transmission of water pump data to obtain a transmission effect evaluation index. The transmission effect evaluation index is used to quantify the effect of wireless transmission of water pump data. A comprehensive evaluation result feedback module is used to perform a comprehensive evaluation based on the transmission effect evaluation index and the preset transmission effect threshold range in combination with the water pump operation evaluation index to obtain a comprehensive evaluation result.

[0033] In this embodiment, the preset key positions of the water pump include the water inlet of the water pump, the water outlet of the water pump, the power supply of the water pump motor and the positions of each bearing of the water pump, so as to ensure that the water pump operates under normal operating conditions, thereby achieving the improvement of the quality of wireless transmission of the water pump operating parameters, thereby improving the accuracy of transmission control of the water pump operating parameters.

[0034] Furthermore, the preset key positions of the water pump include the water pump inlet, the water pump outlet, the water pump motor power inlet and the positions of each water pump bearing; the real-time parameters include the water pump inlet pressure, the water pump outlet flow, the water pump outlet pressure, the water pump motor power supply current, the water pump motor power supply voltage, the water pump bearing vibration amplitude, the water pump bearing temperature, the water pump running time and the total water output of the water pump.

[0037] In this embodiment, since the real-time parameters collected by the sensor may contain noise, outliers or erroneous values, the real-time parameters need to be preprocessed to ensure the accuracy of subsequent analysis; data cleaning refers to using visualization tools (such as heat maps) to identify missing values ​​for the acquired real-time environmental data and filling the missing values ​​through interpolation methods, such as the mean interpolation method to calculate the mean of the column containing missing values, replace the missing values ​​in the column with the mean, and use statistical methods (such as box plots) to identify outliers and delete them. Box plots are a common graphical method for identifying outliers. They visualize the distribution of data based on quartiles and intuitively display outliers. The "whiskers" of the box plot represent the normal range of the data, and data points outside the whiskers are considered outliers. The output of the sensor may have different dimensions or ranges, which can be converted to the same dimension or standardized range through data normalization for unified processing. For example, the data is converted to a normal distribution with a mean of 0 and a standard deviation of 1 through Z-score standardization. The second operating data is transformed through the logarithmic transformation method and then fused through the Kalman filter. The logarithmic transformation method can be used for time series data showing exponential growth. Taking the logarithm can help eliminate the growth trend and make it easier to process.

When used, the weight corresponding to the preset operating fault temperature can be directly obtained from the preset database, and the corresponding relationship can be a preset mapping relationship. For example, the operating fault temperature of the water pump and the weight corresponding to the operating fault temperature of the water pump preset in the preset database form a mapping set, and the real-time operating fault temperature of the water pump is input into the mapping set to obtain the corresponding weight. The mapping relationship can be one-to-one or many-to-one. In this example, the value range is [0, 1].

[0048] In this example, the sum of the operating fault vibration weight, the operating fault temperature weight, and the operating fault current weight is 1. The operating fault current weight is used to describe the influence of the current in the water pump operating fault on the water pump operating fault.

[0049] like Figure 2 As shown, it is a change graph of the water pump operation evaluation index provided in an embodiment of the present application, wherein the following settings are set: the number of preset time intervals is 1, the operation efficiency weight is 0.5, the average current of the water pump motor power supply inlet is 10A, the average voltage of the water pump motor power supply inlet is 220V, the motor efficiency influencing factor is 0.9, the operation fault weight is 0.2, the operation fault vibration weight is 0.3, the operation fault temperature weight is 0.4, the operation fault current weight is 0.3, the operation energy consumption weight is 0.3, the total working time of the water pump is 3600 seconds, the total water consumption of the water pump is 1000 liters, the optimal water pump bearing vibration amplitude is 0.1, the optimal water pump bearing temperature is 60 degrees Celsius, and the optimal water pump motor power supply inlet current is 10A; it can be seen from the figure that when the average current of the water pump motor power supply inlet and the average voltage of the water pump motor power supply inlet are a certain value, as the average water pump outlet flow rate and the average water pump outlet pressure increase, the water pump operation evaluation index increases accordingly.

[0050] The water pump operation evaluation index is used to evaluate the operating status of the water pump. The water pump operation evaluation index is obtained by quantitatively considering the correlation and mutual influence between various factors and performing comprehensive analysis. For example, when the average current of the water pump motor power inlet and the average voltage of the water pump motor power inlet are fixed values, if the average flow rate at the water pump outlet and the average pressure at the water pump outlet increase, it indicates that the water pump efficiency is high. However, at this time, it is also necessary to consider whether the average vibration amplitude of the water pump bearing and the average temperature of the water pump bearing deviate from the optimal water pump bearing vibration amplitude and the optimal water pump bearing temperature. As the average water pump bearing temperature increases, the water pump bearing temperature increases. The increase in the value may cause changes in the metal material properties of the bearing, and even cause material expansion and deformation, which will increase the average vibration amplitude of the water pump bearing. When the average vibration amplitude of the water pump bearing increases, it means that the bearing has been subjected to additional mechanical shock or wear, resulting in increased friction. The increased friction will aggravate the heat accumulation inside the bearing, thereby causing the average temperature of the water pump bearing to rise. The stronger the vibration, the faster the friction growth rate, and the more obvious the trend of the average water pump bearing temperature increase. In addition, the various parameters are related and do not exist independently. The numerical evaluation of the operating status of the water pump is realized.

[0051] Furthermore, whether to execute wireless transmission of water pump data is determined based on the water pump operation evaluation index and the preset operation evaluation threshold range, and the following steps are also included: if the water pump operation evaluation index exceeds the preset operation evaluation threshold range, the water pump data is not wirelessly transmitted, and water pump operation evaluation feedback is performed at the same time, and preset personnel are reminded via text messages to detect abnormal operation status of the water pump; if the water pump operation evaluation index is within the preset operation evaluation threshold range, the water pump data is encrypted before wireless transmission, and the water pump data is backed up in real time and uploaded to cloud storage.

[0052] In this embodiment, if the water pump data is not transmitted wirelessly, a preset personnel will be reminded via text message to detect the abnormal operating status of the water pump. The abnormal operating status detection of the water pump includes troubleshooting and repair operations, specifically including cleaning the pipes and replacing water pump parts; the water pump data is encrypted before wireless transmission. The encryption process can use a symmetric encryption algorithm or an asymmetric encryption algorithm to ensure that the water pump data will not be eavesdropped or tampered with during the wireless transmission process; based on the judgment of the water pump operation evaluation index and the preset operation evaluation threshold range, the transmission of unreliable data when the water pump operation status is abnormal can be avoided, thereby improving the effectiveness of water pump data transmission.

[0053] Furthermore, the specific steps for evaluating the effect of wireless transmission of water pump data to obtain a transmission effect evaluation index are as follows: obtaining the operating parameters within a preset time interval, the standard deviation of the operating parameters, and the actually received operating parameters of a preset remote monitoring center, the actually received operating parameters are used to describe the operating parameters of the sensor on the water pump received by the remote monitoring center of the water pump operating parameters through wireless transmission; obtaining the water pump transmission data during the wireless transmission of water pump data within a preset time interval, the water pump transmission data includes the average transmission signal strength, the average transmission rate, the transmission packet loss rate, and the transmission delay; combining the operating parameters, the standard deviation of the operating parameters, the actually received operating parameters, and the water pump transmission data with the environmental impact factors obtained from the preset database and the transmission effect evaluation weights to obtain the transmission effect evaluation index.

[0054] Among them, the transmission effect evaluation weight includes a transmission stability performance weight and a transmission accuracy performance weight. The transmission stability performance weight is used to describe the influence of the stability performance of the wireless transmission of water pump data on the transmission effect evaluation index. Specifically, the transmission stability performance is the weight corresponding to the transmission stability performance preset in the preset database, which represents the numerical value of the influence of the stability performance of the wireless transmission of water pump data on the transmission effect evaluation index. When used, the weight corresponding to the preset transmission stability performance can be directly obtained from the preset database, and the corresponding relationship can be a pre-set mapping relationship. For example, the stability performance of the wireless transmission of water pump data and the weight corresponding to the stability performance of the wireless transmission of water pump data preset in the preset database form a mapping set, and the stability performance of the wireless transmission of real-time water pump data is input into the mapping set to obtain the corresponding weight. The mapping relationship can be one-to-one or many-to-one. In this example, the value range is [0, 1]; the transmission accuracy performance weight is used to describe the influence of the accuracy performance of the wireless transmission of water pump data on the transmission effect evaluation index. In this example, the sum of the transmission effect evaluation weight and the transmission accuracy performance weight is 1.

[0055] The transmission effect evaluation index is calculated using the following formula:

[0056] ;

[0057] ;

[0058] In the formula, represents the transmission effect evaluation index within the fth preset time interval, represents the transmission stability performance weight, represents the average transmission signal strength in the fth preset time interval, represents the average transmission rate in the fth preset time interval, represents the transmission packet loss rate within the fth preset time interval, represents the transmission delay within the fth preset time interval, represents the environmental impact factor, represents the receiving error coefficient of the a-th type operating parameter, Indicates the number of preset time intervals, , Indicates the total number of preset time intervals, represents the transmission accuracy performance weight, represents the standard deviation of the a-th type of operating parameter in the f-th preset time interval, Indicates the number of categories of operating parameters, , Indicates the total number of categories of operating parameters, represents the a-th type of operating parameters in the f-th preset time interval, Indicates the actual receiving operating parameters of the ath type in the fth preset time interval.

[0059] Specific assumptions: the preset time interval is 1, the total number of categories of operating parameters is 1, and the specific assumption is that the category of the operating parameter is the water pump bearing temperature, the transmission stability performance weight is 0.5, the transmission accuracy performance weight is 0.5, the average transmission signal strength is 5dBm, the average transmission rate is 15kbps, the transmission packet loss rate is 0.7, the transmission delay is 22ms, and the environmental impact factor is 3. The above method can be used to calculate the transmission effect evaluation index. The statistical table of the change of the transmission effect evaluation index is shown in Table 1:

[0060] Table 1 Statistics of changes in transmission effect evaluation index

[0061]

[0062] The transmission effect evaluation index is used to quantify the wireless transmission effect of water pump data; among them, the transmission effect evaluation index includes parameters in multiple aspects, and the various parameters are related, not independent, and not obtained by simple combination and addition; for example, even if the transmission delay is small, it does not necessarily mean that the transmission effect evaluation index is large, and the receiving error coefficient must be considered at this time; as shown in Table 1, when the transmission signal strength, average transmission rate, packet loss rate and transmission delay are fixed values, as the receiving error coefficient decreases, the transmission effect evaluation index increases; and as the transmission signal strength increases, the signal's anti-interference ability increases, and the packet loss rate decreases; and as the packet loss rate increases, in order to reduce the packet loss rate, the average transmission rate will decrease, and the transmission delay will increase; as the transmission signal strength increases, the average transmission rate increases, the packet loss rate decreases, the transmission delay decreases, and the transmission effect evaluation index increases; a more accurate evaluation of the wireless transmission effect of water pump data is achieved.

[0063] Furthermore, the specific steps of conducting a comprehensive evaluation based on the transmission effect evaluation index and the preset transmission effect threshold range in combination with the water pump operation evaluation index to obtain a comprehensive evaluation result are as follows: comparing the obtained water pump operation evaluation index with the corresponding preset operation evaluation threshold range to obtain a water pump operation evaluation result; if the water pump operation evaluation index exceeds the preset operation evaluation threshold range, the water pump operation evaluation result is recorded as abnormal water pump operation and no wireless transmission of water pump data is performed; otherwise, the water pump operation evaluation result is recorded as normal water pump operation and wireless transmission of water pump data is performed; comparing the obtained transmission effect evaluation index with the corresponding preset transmission effect threshold range to obtain a transmission effect evaluation result; if the transmission effect evaluation index is within the preset transmission effect threshold range, the transmission effect evaluation result is recorded as normal water pump operation and normal wireless transmission of water pump data; otherwise, the transmission effect evaluation result is recorded as normal water pump operation and abnormal wireless transmission of water pump data; the comprehensive evaluation result includes the water pump operation evaluation result and the transmission effect evaluation result.

[0064] In this embodiment, the preset transmission effect threshold range is set by professionals according to standards in the field. For example, the preset transmission effect threshold range can be determined by setting the average transmission signal strength range (-50dBm to -80dBm), the average transmission rate range (50kbps to 100kbps), the transmission packet loss rate range (0% to 1%), the transmission delay range (50ms to 100ms) and the receiving error coefficient range (5 to 10); through the dual evaluation of the water pump operating status and the water pump data transmission effect, the comprehensive evaluation result is used to reflect the water pump operating status and the water pump data transmission effect, so as to facilitate the preset personnel to better perform the transmission control and monitoring of the water pump operating parameters, thereby realizing the transmission control of the water pump operating parameters.

[0065] like Figure 3 As shown, it is a flow chart of a method for wireless transmission and remote monitoring of water pump operating parameters provided in an embodiment of the present application, which is applied to a system for wireless transmission and remote monitoring of water pump operating parameters, and the method includes the following steps: S1, collecting real-time parameters within a preset time interval through sensors, preprocessing the real-time parameters to obtain operating parameters, and the sensors are deployed at preset key positions of the water pump; S2, evaluating the operating status of the water pump to obtain a water pump operation evaluation index, and judging whether to execute wireless transmission of water pump data based on the water pump operation evaluation index and a preset operation evaluation threshold range, the water pump operation evaluation index is used to evaluate the operating status of the water pump, and the water pump data includes the water pump operation evaluation index and operating parameters; S3, after executing the wireless transmission of the water pump data, evaluating the effect of the wireless transmission of the water pump data to obtain a transmission effect evaluation index, and the transmission effect evaluation index is used to quantify the effect of the wireless transmission of the water pump data; S4, performing a comprehensive evaluation based on the transmission effect evaluation index and the preset transmission effect threshold range and in combination with the water pump operation evaluation index to obtain a comprehensive evaluation result.

[0066] In this embodiment, preprocessing can ensure that the water pump operating parameters are of high quality and operability, and the operating parameters are used to describe the operating status of the water pump; wherein, the comprehensive evaluation results include water pump operation evaluation results and transmission effect evaluation results; through all-round monitoring of the water pump operation, the accuracy of the transmission control of the water pump operating parameters is improved.

[0067] To summarize, the embodiment of the present application evaluates the operating status of the water pump to obtain a water pump operation evaluation index and determines whether to execute wireless transmission of water pump data, then evaluates the effect of wireless transmission of water pump data to obtain a transmission effect evaluation index, and finally performs a comprehensive evaluation to obtain a comprehensive evaluation result, thereby realizing the monitoring of the water pump operating status and wireless transmission of water pump data and feedback of abnormal situations, and further more accurately performing transmission control of water pump operating parameters, effectively solving the problem of inaccurate transmission control of water pump operating parameters in chemical production in the prior art.
