Description

Technical Field

[0001] The present invention relates to the technical field of scale inhibition effect monitoring, and in particular to a real-time monitoring method and a monitoring system for scale inhibition effect of electric pulse water treatment. Background Art

[0002] With the development of modern society, water resources, a vital component of human life and work, are becoming increasingly polluted. To prevent excessive water waste, the government has implemented a series of regulations for industrial wastewater discharge, requiring it to meet standards before it can be discharged, thereby facilitating its secondary use. Industrial wastewater, whether treated or not, contains impurities. These impurities or sediment can easily remain in pipes and form scale on the pipe walls. Scale not only affects water flow but also reduces heat transfer. Currently, chemical and physical treatment methods are used to prevent scale buildup.

[0003] The commonly used chemical treatment method is to add scale inhibitors to the water, which have the function of dispersing insoluble inorganic salts in the water and preventing or interfering with the precipitation and scaling of insoluble inorganic salts on the metal surface. The commonly used scale inhibitors are phosphorus-based corrosion inhibitors; however, scale inhibitors are external agents and can easily cause secondary pollution of the water body.

[0004] There are many methods for physically treating industrial circulating water. In addition to magnetization, high-voltage electrostatic field treatment, ultrasonic treatment, and high-frequency electromagnetic field treatment, the most popular method is electric pulse water treatment. This method inhibits scale by applying a periodic damped oscillating electric pulse signal to the water to be treated. The effectiveness of this method is closely related to the shape and energy of the periodic damped oscillating electric pulse signal in the water. Based on these methods, a variety of physical industrial circulating water treatment devices have been developed.

[0005] Neither chemical nor physical treatment methods can monitor the scale inhibition effect in real time. In addition, there is no means to monitor the degree of scaling in the existing technology. Summary of the Invention

[0006] The main purpose of the present invention is to provide a real-time monitoring method, monitoring system, electronic device and computer-readable storage medium for the scale inhibition effect of electric pulse water treatment to solve the technical problem in the prior art that the scale inhibition effect and scaling degree cannot be monitored in real time.

[0007] In order to solve the above technical problems, the present invention first provides a real-time monitoring method for the scale inhibition effect of electric pulse water treatment. The technical solution is as follows:

[0010] S200, calculating the similarity between the voltage data and a preset electric pulse oscillation waveform signal;

[0011] If the similarity is lower than the preset similarity threshold, then step S100 is performed after outputting the similarity; if the similarity is higher than the preset similarity threshold, then step S300 is performed;

[0012] S300, obtaining a damped oscillation waveform by fitting the voltage data;

[0013] S400 , in each oscillation cycle, multiplying and accumulating the current data and the voltage data at the same time to obtain the energy value of each oscillation cycle;

[0014] If the energy value is lower than the preset energy value threshold, step S100 is performed after outputting the energy value; if the energy value is higher than the preset energy value threshold, step S100 is performed directly.

[0015] Furthermore, the similarity adopts cosine similarity.

[0016] Furthermore, the similarity threshold is 0.9.

[0017] Furthermore, the amplitude, phase, damping factor and frequency of the voltage data are processed using the Prony algorithm to obtain a damped oscillation waveform.

[0018] Furthermore, in S100 , the current data and voltage data in the pipeline are synchronously acquired by the synchronous triggering device.

[0019] Furthermore, the current data is a digital voltage signal, and the current data is a digital current signal.

[0020] Furthermore, when the similarity is lower than a preset similarity threshold and / or the energy value is lower than a preset energy value threshold, the pulse frequency and / or amplitude of the electric pulse water treatment and antiscaling device is immediately adjusted.

[0021] In order to solve the above technical problems, the present invention provides a real-time monitoring system for the scale inhibition effect of electric pulse water treatment. The technical solution is as follows:

DETAILED DESCRIPTION

[0042] The present invention is described clearly and completely below with reference to the accompanying drawings. A person skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be noted that:

[0043] The technical solutions and technical features provided in each part of the present invention, including the following description, may be combined with each other unless there is any conflict.

[0044] In addition, the embodiments of the present invention described below are generally only part of the embodiments of the present invention, rather than all of the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts should fall within the scope of protection of the present invention.

[0045] Regarding the terms and units in the present invention: The terms "include", "have" and any variations thereof in the description and claims of the present invention and the related parts are intended to cover non-exclusive inclusions.

[0046] Figure 1 This is a flow chart of an embodiment of a method for real-time monitoring of scale inhibition effect of electric pulse water treatment according to the present invention.

[0047] like Figure 1 As shown, the real-time monitoring method for scale inhibition effect of electric pulse water treatment includes the following steps:

[0048] S100, obtaining current data and voltage data in the pipeline;

[0049] S200, calculating the similarity between the voltage data and a preset electric pulse oscillation waveform signal;

[0050] If the similarity is lower than the preset similarity threshold, then step S100 is performed after outputting the similarity; if the similarity is higher than the preset similarity threshold, then step S300 is performed;

[0051] S300, obtaining a damped oscillation waveform by fitting the voltage data;

[0052] S400 , in each oscillation cycle, multiplying and accumulating the current data and the voltage data at the same time to obtain the energy value of each oscillation cycle;

[0053] If the energy value is lower than the preset energy value threshold, step S100 is performed after outputting the energy value; if the energy value is higher than the preset energy value threshold, step S100 is performed directly.

[0054] The similarity is measured using cosine similarity, also known as cosine similarity. This measure evaluates the similarity between two vectors by calculating the cosine of the angle between them. Unlike other similarity measures, such as Euclidean distance, cosine similarity is less sensitive to absolute values ​​and focuses more on distinguishing differences in direction. This makes it well-suited for use in determining whether the shapes of two signals are similar.

[0055] After multiple field measurements, we found that when the cosine similarity is lower than 0.9, the difference between the two waveforms is more obvious. The closer the cosine similarity is to 1, the more similar the two waveforms are; therefore, the similarity threshold is 0.9.

[0056] The Prony algorithm is used to process the amplitude, phase, damping factor, and frequency of the voltage data to obtain a damped oscillation waveform. The Prony method uses a linear combination of a set of exponential terms to fit equally spaced sampled data. Compared to the fast Fourier transform, the Prony algorithm can obtain the low-frequency content in the signal with a short sampling time, and the interval between the calculated frequencies (resolution) is independent of the sampling time, resulting in a high resolution. The calculated result also contains the attenuation coefficient, making it suitable for scenarios in the present invention where the amplitude, phase, damping factor, and frequency need to be calculated simultaneously and the sampling time is short.

[0057] The current data and voltage data in the pipeline in S100 are synchronously acquired by the synchronous triggering device; thereby, it is convenient to acquire the values ​​of the synchronized current data and voltage data at the same time in S400.

[0058] The current data is a digital voltage signal, and the current data is a digital current signal. Compared with analog signals, digital signals have strong anti-interference capabilities, no noise accumulation, and are easy to store, process, and exchange, which is suitable for the working conditions of the present invention and the scenarios that require storage and processing.

[0059] When the similarity is lower than the preset similarity threshold and / or the energy value is lower than the preset energy value threshold, the pulse frequency and / or amplitude of the electric pulse water treatment and scale inhibition equipment is immediately adjusted; thereby, the operation of the electric pulse water treatment and scale inhibition equipment can be more reasonably controlled, for example, the operating parameters of the electric pulse water treatment and scale inhibition equipment can be adjusted in real time, thereby significantly improving the scale inhibition effect.
