Technical Field

[0001] This invention relates to the field of cement screening machine monitoring technology, and in particular to a monitoring system for a cement screening machine. Background Technology

[0002] Cement screening machines are key pieces of equipment widely used in the cement production process. Their main function is to accurately screen and grade cement raw materials to ensure that the final cement product possesses high quality and stable processing characteristics. This equipment effectively removes impurities and substandard particles from the raw materials through meticulous separation, providing crucial quality assurance for cement production.

[0003] In traditional cement screening machine operation, due to the complexity of the production environment and the characteristics of long-term equipment operation, problems such as equipment wear, blockage, and abnormal vibration may occur. These problems not only affect the working efficiency of the screening machine, but may also lead to production interruption and increased maintenance costs.

[0004] Therefore, there is an urgent need to invent a preset system for monitoring the screening process of the cement screening machine, in order to solve the problem that traditional cement screening machines cannot detect potential problems in time during screening operation, which leads to damage to the cement screening machine, resulting in production interruption and increased maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to provide a monitoring system for cement screening machines, which aims to solve the problem that traditional cement screening machines cannot detect potential problems in a timely manner during screening operation, resulting in damage to the cement screening machine, production interruption, and increased maintenance costs.

[0006] On one hand, this invention provides a monitoring system for a cement screening machine, comprising:

[0007] A detection module is installed at the discharge port of the cement screening machine. The detection module is used to detect the cement discharge flow rate and the diameter of the discharged cement particles.

[0008] A vibration detection module is installed inside the cement screening machine. The vibration detection module is used to detect the vibration frequency and surface wear of the screen.

[0009] The scoring module is electrically connected to the detection module and the vibration detection module respectively. The scoring module is used to adjust the working score of the cement screening machine based on the cement discharge flow rate and discharge cement particle diameter of the cement screening machine detected by the detection module, as well as the vibration frequency and surface wear of the screen.

[0010] An alarm module is electrically connected to the scoring module. The alarm module is used to determine the warning level of the cement screening machine based on the relationship between the adjusted work score of the scoring module and the preset work score.

[0011] A communication module is electrically connected to the alarm module, and the communication module is used to send the warning level of the cement screening machine determined by the alarm module.

[0012] Furthermore, the scoring module is also used to obtain the real-time cement discharge flow rate L of the cement screening machine, and the scoring module is also used to determine whether the cement discharge flow rate of the cement screening machine is normal based on the relationship between the real-time cement discharge flow rate L and the preset cement discharge flow rate L0.

[0013] When L = L0, the scoring module determines that the cement discharge flow rate of the cement screening machine is equal to the preset discharge flow rate, and determines whether the cement discharge flow rate of the cement screening machine is normal.

[0014] When L > L0 and L < L0, the scoring module determines that the cement discharge flow rate of the cement screening machine is greater than or less than the preset discharge flow rate, and determines that the cement discharge flow rate of the cement screening machine is abnormal. Based on the relationship between the real-time cement discharge flow rate L and the preset cement discharge flow rate L0, the working score of the cement screening machine is adjusted.

[0015] Furthermore, when the scoring module determines that the cement discharge flow rate of the cement screening machine is abnormal, and adjusts the working score of the cement screening machine based on the relationship between the real-time cement discharge flow rate L and the preset cement discharge flow rate L0, it includes:

[0022] When the scoring module selects the i-th preset adjustment coefficient Mi to adjust the working score of the cement screening machine, i = 1, 2, 3, and determines the adjusted working score of the cement screening machine as Q1, Q1 = Q * Mi, where Q is the initial working score of the cement screening machine.

[0023] Furthermore, when the scoring module selects the i-th preset adjustment coefficient Mi to adjust the working score of the cement screening machine, and determines the adjusted working score of the cement screening machine as Q1, it includes:

[0024] The scoring module is also used to obtain the real-time diameter K of the largest cement particle among the diameters of the cement particles discharged from the cement screening machine. The scoring module is also used to determine whether the cement particles discharged from the cement screening machine are qualified based on the relationship between the real-time diameter K of the largest cement particle and the preset diameter K0 of the largest cement particle.

[0025] When K≤K0, the scoring module determines that the output cement particles of the cement screening machine are less than or equal to the preset maximum diameter of cement particles, and determines that the output cement particles of the cement screening machine are qualified.

[0026] When K > K0, the scoring module determines that the cement particles discharged from the cement screening machine are larger than the preset maximum cement particle diameter, and judges that the cement particles discharged from the cement screening machine are unqualified. Based on the relationship between the real-time diameter K of the maximum cement particle and the preset maximum cement particle diameter K0, the working score Q1 of the cement screening machine is corrected.

[0027] Furthermore, when the scoring module determines that the cement particles discharged from the cement screening machine are unqualified, and corrects the adjusted working score Q1 of the cement screening machine based on the relationship between the real-time diameter K of the largest cement particle and the preset diameter K0 of the largest cement particle, it includes:

[0034] Furthermore, when the scoring module selects the i-th preset correction coefficient Ni to correct the adjusted working score Q1 of the cement screening machine, and determines the corrected working score of the cement screening machine as Q2, it includes:

[0035] The scoring module is also used to obtain the current wear degree J of the screen surface, and the scoring module is also used to determine whether the screen is damaged based on the relationship between the current wear degree J of the screen surface and the preset screen surface wear degree J0.

[0036] When J≤J0, the scoring module determines that the current wear degree J of the screen surface is less than or equal to the preset screen surface wear degree, and determines that the screen is not damaged.

[0037] When J > J0, the scoring module determines that the current wear degree J of the screen surface is greater than the preset screen surface wear degree, and determines that the screen has been damaged. Based on the relationship between the current wear degree J of the screen surface and the preset screen surface wear degree J0, the working score Q2 of the cement screening machine is corrected.

[0038] Furthermore, when the scoring module determines that the screen has been damaged, and corrects the working score Q2 of the cement screening machine based on the relationship between the current wear degree J of the screen surface and the preset screen surface wear degree J0, it includes:

[0039] The scoring module is also used to obtain the wear difference value △J between the current wear degree J of the screen surface and the preset wear degree J0 of the screen surface, △J = J - J0. The scoring module is also used to compare the wear difference value △J with the preset wear difference value, and select the corresponding correction coefficient according to the comparison result to correct the working score Q2 of the cement screening machine after correction.

[0040] The scoring module is also used to pre-set a first preset wear difference value △J1 and a second preset wear difference value △J2. The scoring module is also used to pre-set a first preset correction coefficient B1, a second preset correction coefficient B2 and a third preset correction coefficient B3, where △J1 < △J2, 0.5 < B1 < B2 < B3 < 1.

[0043] When △J>△J2, the third preset correction coefficient B3 is selected to correct the working score Q2 of the cement screening machine after correction;

[0044] When the scoring module selects the i-th preset correction coefficient Bi to correct the corrected working score Q2 of the cement screening machine, i = 1, 2, 3, and determines the corrected working score of the cement screening machine as Q3, Q3 = Q2 * Bi.

[0045] Furthermore, when the scoring module selects the i-th preset correction coefficient Bi to correct the corrected working score Q2 of the cement screening machine, and determines the corrected working score of the cement screening machine as Q3, it includes:

[0046] The scoring module is also used to obtain the real-time vibration frequency H of the screen, and the scoring module is also used to determine whether the vibration of the screen is in a normal working state based on the relationship between the real-time vibration frequency H of the screen and the preset vibration frequency H0 of the screen.

[0047] When H = H0, the scoring module determines that the vibration frequency of the screen during operation is equal to the preset vibration frequency, and determines that the vibration of the screen during operation is in normal working condition.

[0048] When H > H0 and H < H0, the scoring module determines that the vibration frequency of the screen during operation is less than or greater than the preset vibration frequency, and determines that the vibration of the screen during operation is in an abnormal working state. Based on the relationship between the real-time vibration frequency H of the screen and the preset vibration frequency H0 of the screen, the working score Q3 of the cement screening machine is corrected.

[0049] Furthermore, when the scoring module determines that the vibration of the screen is in an abnormal working state, and corrects the working score Q3 of the cement screening machine based on the relationship between the real-time vibration frequency H of the screen and the preset vibration frequency H0 of the screen, it includes:

The scoring module is also used to compare the vibration frequency difference value △H with the preset vibration frequency difference value, and select the corresponding correction coefficient according to the comparison result to correct the working score Q3 of the cement screening machine after correction.

[0051] The scoring module is also used to pre-set a first preset vibration frequency difference value △H1 and a second preset vibration frequency difference value △H2. The scoring module is also used to pre-set a first preset correction coefficient V1, a second preset correction coefficient V2 and a third preset correction coefficient V3, where △H1 < 0 < △H2, V1 < V2 < V3 < 1.

[0052] When △H≤△H1, the first preset correction coefficient V1 is selected to correct the working score Q3 of the cement screening machine after correction;

[0055] When △H>△H2, the third preset correction coefficient V3 is selected to correct the working score Q3 of the cement screening machine after correction;

[0056] When the scoring module selects the i-th preset correction coefficient Vi to correct the working score Q3 of the cement screening machine, i = 1, 2, 3, and determines the corrected working score of the cement screening machine as Q4, Q4 = Q3 * Vi.

[0057] Furthermore, when determining the warning level of the cement screening machine based on the relationship between the adjusted work score and the preset work score, the alarm module includes:

[0058] The alarm module is also used to obtain the working score Q4 of the cement screening machine after being corrected by the scoring module;

[0059] The alarm module is also used to preset the working score T1 of the first preset cement screening machine and the working score T2 of the second preset cement screening machine. The alarm module is also used to preset the first preset warning level E1, the second preset warning level E2 and the third preset warning level E3, and T1 < T2, E1 < E2 < E3.

[0060] When Q4≤T1, the alarm module selects the first preset warning level E1 as the warning level of the cement screening machine;

[0063] When the alarm module selects the i-th preset warning level Ei as the warning level of the cement screening machine, i = 1, 2, 3, and determines the warning level of the cement screening machine as Ei.

[0064] Compared with existing technologies, the monitoring system for a cement screening machine in this embodiment of the invention offers the following advantages: Firstly, by setting up detection and vibration detection modules, real-time monitoring of key parameters of the cement screening machine is achieved, including cement discharge flow rate, discharge cement particle diameter, screen vibration frequency, and screen surface wear. This helps to promptly detect changes and abnormalities during the operation of the cement screening machine. Secondly, through the scoring module, the system can comprehensively evaluate and adjust the working score of the cement screening machine based on the detected parameters. This allows the system to dynamically adjust the equipment performance according to actual working conditions, helping to improve the working efficiency of the screening machine and the quality of cement products. Simultaneously, by equipping an alarm module, the warning level of the cement screening machine is determined based on the relationship between the adjusted working score and the preset working score. This allows operators to quickly understand the operating status of the equipment and take timely maintenance measures, thereby reducing the impact of potential faults on production. Finally, through the communication module, the system can send the determined warning level of the cement screening machine to relevant personnel, realizing remote monitoring and management. This improves the efficiency of information transmission, enabling production managers to understand the equipment status in real time and formulate corresponding maintenance plans and production scheduling in a timely manner.

[0066] Figure 2 This is a flowchart of a monitoring system for a cement screening machine according to an embodiment of the present invention. Detailed Implementation

[0067] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0068] like Figure 1 and Figure 2As shown, a monitoring system for a cement screening machine according to an embodiment of the present invention includes: a detection module, a vibration detection module, a scoring module, an alarm module, and a communication module. The detection module is located at the discharge port of the cement screening machine and is used to detect the cement discharge flow rate and the diameter of the discharged cement particles. The vibration detection module is located inside the cement screening machine and is used to detect the vibration frequency and surface wear of the screen. The scoring module is electrically connected to both the detection module and the vibration detection module, and is used to adjust the working score of the cement screening machine based on the cement discharge flow rate, the diameter of the discharged cement particles, the vibration frequency, and the surface wear of the screen detected by the detection modules. The alarm module is electrically connected to the scoring module and is used to determine the warning level of the cement screening machine based on the relationship between the adjusted working score and the preset working score. The communication module is electrically connected to the alarm module and is used to send the warning level of the cement screening machine determined by the alarm module.

[0069] Understandably, by setting a detection module at the discharge port of the cement screening machine, accurate detection of the cement discharge flow rate and the diameter of the discharged cement particles is achieved. Simultaneously, the vibration detection module, located inside the cement screening machine, effectively monitors the vibration frequency and surface wear of the screen. This allows for a comprehensive understanding of the cement screening machine's operating status, enabling timely detection of potential problems. Secondly, the scoring module, through electrical connection with the detection and vibration detection modules, comprehensively considers multiple parameters such as cement discharge flow rate, discharged cement particle diameter, screen vibration frequency, and surface wear to adjust the cement screening machine's performance score. This comprehensive scoring method helps to more accurately reflect the overall performance of the equipment, providing operators with more comprehensive information. Thirdly, the introduction of an alarm module electrically connected to the scoring module enables the determination of the cement screening machine's warning level based on the relationship between the adjusted performance score and the preset score. This intelligent warning system allows operators to quickly understand the equipment's operating status, detect potential faults or anomalies in advance, and help reduce downtime and maintenance costs. Finally, through the application of a communication module, the system can remotely send the determined cement screening machine warning level, achieving remote monitoring and real-time management of the equipment status. This provides production managers with a convenient means to take timely and necessary actions to ensure the smooth operation of production.

[0070] In a specific embodiment of this application, the above steps are implemented as follows: A detection module is installed at the discharge port of the cement screening machine, using sensors to detect the cement discharge flow rate and the diameter of the discharged cement particles in real time. A vibration detection module is located inside the cement screening machine, using vibration sensors to monitor the vibration frequency and surface wear of the screen. A scoring module is connected to the detection module and the vibration detection module, using advanced algorithms and real-time data to comprehensively evaluate multiple parameters of the cement screening machine, such as the cement discharge flow rate, the diameter of the discharged cement particles, and the vibration frequency and surface wear of the screen. If the scoring module detects that some parameters are abnormal or close to critical values, the system will adjust the working score of the cement screening machine accordingly. An alarm module is connected to the scoring module, and by comparing the adjusted working score with the preset working score in real time, it determines the warning level of the cement screening machine. For example, if the scoring module finds that the cement discharge flow rate decreases, the particle diameter increases, and the screen frequency increases and the surface wear increases significantly, the system may determine that the equipment may be faulty or needs maintenance, thereby triggering the corresponding warning level. Finally, the communication module connects to the alarm module, sending the determined warning level of the cement screening machine to a designated receiver. For example, this information can be transmitted to production managers via mobile application, email, or other remote monitoring platforms, enabling them to take timely measures to ensure the normal operation of the equipment and avoid potential production interruptions and increased costs. This system structure and functionality allows manufacturers to manage cement screening machines more intelligently, improving production efficiency and equipment reliability.

[0071] The above scenarios are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0072] Specifically, in some embodiments of the present invention, the scoring module is further used to obtain the real-time cement discharge flow rate L of the cement screening machine. The scoring module is also used to determine whether the cement discharge flow rate of the cement screening machine is normal based on the relationship between the real-time cement discharge flow rate L and the preset cement discharge flow rate L0: When L = L0, the scoring module determines that the cement discharge flow rate of the cement screening machine is equal to the preset discharge flow rate, and thus determines whether the cement discharge flow rate of the cement screening machine is normal. When L > L0 or L < L0, the scoring module determines that the cement discharge flow rate of the cement screening machine is greater than or less than the preset discharge flow rate, and thus determines that the cement discharge flow rate of the cement screening machine is abnormal. Based on the relationship between the real-time cement discharge flow rate L and the preset cement discharge flow rate L0, the scoring module adjusts the working score of the cement screening machine.

[0073] Specifically, in some embodiments of the present invention, when the scoring module determines that the cement discharge flow rate of the cement screening machine is abnormal, and adjusts the working score of the cement screening machine according to the relationship between the real-time cement discharge flow rate L and the preset cement discharge flow rate L0, the scoring module is further used to obtain the discharge flow rate difference ΔL between the real-time cement discharge flow rate L and the preset cement discharge flow rate L0, where ΔL = L - L0. The scoring module is further used to compare the discharge flow rate difference ΔL with the preset discharge flow rate difference, and select the corresponding adjustment coefficient to adjust the working score of the cement screening machine according to the comparison result. In this case, the scoring module is further used to pre-set a first preset discharge flow rate difference ΔL1 and a second preset discharge flow rate difference ΔL2. The scoring module is also used to pre-set a first preset adjustment coefficient M1, a second preset adjustment coefficient M2 and a third preset adjustment coefficient M3, where ΔL1 < 0 < ΔL2, and M1 < M2 < M3 < 0.5.

[0074] When △L≤△L1, the first preset adjustment coefficient M1 is selected to adjust the working score of the cement screening machine.

[0075] When △L1<△L≤0, the working score of the cement screening machine will not be adjusted.

[0076] When 0 < △L ≤ △L2, the second preset adjustment coefficient M2 is selected to adjust the working score of the cement screening machine.

[0077] When △L>△L2, the third preset adjustment coefficient M3 is selected to adjust the working score of the cement screening machine.

[0078] When the scoring module selects the i-th preset adjustment coefficient Mi to adjust the working score of the cement screening machine, i = 1, 2, 3, and determines the adjusted working score of the cement screening machine as Q1, set Q1 = Q * Mi, where Q is the initial working score of the cement screening machine.

[0079] Specifically, in some embodiments of the present invention, when the scoring module selects the i-th preset adjustment coefficient Mi to adjust the working score of the cement screening machine and determines the adjusted working score of the cement screening machine as Q1, the following steps are included: the scoring module is further used to obtain the real-time diameter K of the largest cement particle among the diameters of the discharged cement particles from the cement screening machine. The scoring module is further used to determine whether the discharged cement particles from the cement screening machine are qualified based on the relationship between the real-time diameter K of the largest cement particle and the preset diameter K0 of the largest cement particle: when K≤K0, the scoring module determines that the discharged cement particles from the cement screening machine are less than or equal to the preset diameter of the largest cement particle, and determines that the discharged cement particles from the cement screening machine are qualified. When K>K0, the scoring module determines that the discharged cement particles from the cement screening machine are greater than the preset diameter of the largest cement particle, and determines that the discharged cement particles from the cement screening machine are unqualified. The adjusted working score Q1 of the cement screening machine is then corrected based on the relationship between the real-time diameter K of the largest cement particle and the preset diameter K0 of the largest cement particle.

[0080] Specifically, in some embodiments of the present invention, when the scoring module determines that the cement particles discharged from the cement screening machine are unqualified, and corrects the adjusted working score Q1 of the cement screening machine based on the relationship between the real-time diameter K of the largest cement particle and the preset diameter K0 of the largest cement particle, the scoring module is further used to obtain the particle diameter difference ΔK between the real-time diameter K of the largest cement particle and the preset diameter K0 of the largest cement particle, ΔK = K - K0. The scoring module is further used to compare the particle diameter difference ΔK with the preset particle diameter difference, and select the corresponding correction coefficient based on the comparison result to correct the adjusted working score Q1 of the cement screening machine. In this case, the scoring module is further used to pre-set the first preset particle diameter difference ΔK1 and the second preset particle diameter difference ΔK2. The scoring module is also used to pre-set the first preset correction coefficient N1, the second preset correction coefficient N2 and the third preset correction coefficient N3, and ΔK1 < ΔK2, 0.2 < N1 < N2 < N3 < 0.75.

[0081] When △K≤△K1, the first preset correction coefficient N1 is selected to correct the adjusted working score Q1 of the cement screening machine.

[0082] When △K1<△K≤△K2, the second preset correction coefficient N2 is selected to correct the adjusted working score Q1 of the cement screening machine.

[0083] When △K>△K2, the third preset correction coefficient N3 is selected to correct the adjusted working score Q1 of the cement screening machine.

[0084] When the scoring module selects the i-th preset correction coefficient Ni to correct the adjusted working score Q1 of the cement screening machine, i = 1, 2, 3, and determines the corrected working score of the cement screening machine as Q2, Q2 = Q1 * Ni.

[0085] Specifically, in some embodiments of the present invention, when the scoring module selects the i-th preset correction coefficient Ni to correct the adjusted working score Q1 of the cement screening machine and determines the corrected working score of the cement screening machine as Q2, the scoring module is further configured to obtain the current surface wear degree J of the screen, and the scoring module is further configured to determine whether the screen is damaged based on the relationship between the current surface wear degree J of the screen and the preset screen surface wear degree J0: when J≤J0, the scoring module determines that the current surface wear degree J of the screen is less than or equal to the preset screen surface wear degree, and determines that the screen is not damaged. When J>J0, the scoring module determines that the current surface wear degree J of the screen is greater than the preset screen surface wear degree, and determines that the screen has been damaged, and corrects the corrected working score Q2 of the cement screening machine based on the relationship between the current surface wear degree J of the screen and the preset screen surface wear degree J0.

[0086] Specifically, in some embodiments of the present invention, when the scoring module determines that the screen has been damaged and corrects the working score Q2 of the cement screening machine based on the relationship between the current wear degree J of the screen surface and the preset wear degree J0 of the screen surface, the scoring module is further used to obtain the wear degree difference value △J between the current wear degree J of the screen surface and the preset wear degree J0 of the screen surface, △J = J - J0. The scoring module is further used to compare the wear degree difference value △J with the preset wear degree difference value and select the corresponding correction coefficient based on the comparison result to correct the working score Q2 of the cement screening machine. In this case, the scoring module is further used to pre-set the first preset wear degree difference value △J1 and the second preset wear degree difference value △J2, and the scoring module is further used to pre-set the first preset correction coefficient B1, the second preset correction coefficient B2 and the third preset correction coefficient B3, and △J1 < △J2, 0.5 < B1 < B2 < B3 < 1.

[0087] When △J≤△J1, the first preset correction coefficient B1 is selected to correct the working score Q2 of the cement screening machine.

[0088] When △J1<△J≤△J2, the second preset correction coefficient B2 is selected to correct the working score Q2 of the cement screening machine.

[0089] When △J>△J2, the third preset correction coefficient B3 is selected to correct the working score Q2 of the cement screening machine.

[0090] When the scoring module selects the i-th preset correction coefficient Bi to correct the working score Q2 of the cement screening machine, i = 1, 2, 3, and determines the working score of the cement screening machine as Q3, Q3 = Q2 * Bi.

[0091] Specifically, in some embodiments of the present invention, when the scoring module selects the i-th preset correction coefficient Bi to correct the working score Q2 of the corrected cement screening machine and determines the working score Q3 of the corrected cement screening machine, the scoring module is further configured to obtain the real-time vibration frequency H of the screen, and the scoring module is further configured to determine whether the vibration of the screen is in a normal working state based on the relationship between the real-time vibration frequency H and the preset vibration frequency H0 of the screen: when H = H0, the scoring module determines that the vibration frequency of the screen is equal to the preset vibration frequency, and determines that the vibration of the screen is in a normal working state. When H > H0 or H < H0, the scoring module determines that the vibration frequency of the screen is less than or greater than the preset vibration frequency, and determines that the vibration of the screen is in an abnormal working state, and corrects the working score Q3 of the corrected cement screening machine based on the relationship between the real-time vibration frequency H and the preset vibration frequency H0 of the screen.

[0092] Specifically, in some embodiments of the present invention, when the scoring module determines that the vibration of the screen is in an abnormal working state and corrects the working score Q3 of the cement screening machine according to the relationship between the real-time vibration frequency H of the screen and the preset vibration frequency H0 of the screen, the scoring module is further used to obtain the vibration frequency difference value ΔH between the real-time vibration frequency H of the screen and the preset vibration frequency H0 of the screen, ΔH = H - H0. The scoring module is further used to compare the vibration frequency difference value ΔH with the preset vibration frequency difference value, and select the corresponding correction coefficient to correct the working score Q3 of the cement screening machine according to the comparison result. In this case, the scoring module is further used to pre-set the first preset vibration frequency difference value ΔH1 and the second preset vibration frequency difference value ΔH2. The scoring module is further used to pre-set the first preset correction coefficient V1, the second preset correction coefficient V2 and the third preset correction coefficient V3, and ΔH1 < 0 < ΔH2, V1 < V2 < V3 < 1.

[0093] When △H≤△H1, the first preset correction coefficient V1 is selected to correct the working score Q3 of the cement screening machine after correction.

[0094] When △H1<△H≤0, the working score Q3 of the corrected cement screening machine will not be corrected.

[0095] When 0 < ΔH ≤ ΔH2, the second preset correction coefficient V2 is selected to correct the working score Q3 of the corrected cement screening machine.

[0096] When △H>△H2, the third preset correction coefficient V3 is selected to correct the working score Q3 of the corrected cement screening machine.

[0097] When the scoring module selects the i-th preset correction coefficient Vi to correct the working score Q3 of the cement screening machine, i = 1, 2, 3, and determines the corrected working score of the cement screening machine as Q4, Q4 = Q3 * Vi.

[0098] Understandably, the detection module monitors the cement discharge flow rate and particle diameter in real time to evaluate the system's performance. By comparing with preset values, abnormal flow rates or particle size issues can be detected promptly, ensuring cement product quality. Secondly, the vibration detection module monitors the screen's vibration frequency and wear, helping to determine the screen's condition. This helps to promptly detect and prevent screen wear problems, improving screening efficiency. Subsequently, the scoring module comprehensively evaluates the cement screening machine's operating status based on multiple parameters, including flow rate, particle diameter, and vibration frequency. This comprehensive evaluation is more thorough and accurate, helping to accurately determine the equipment's operating condition. Simultaneously, the scoring module automatically adjusts the cement screening machine's operating score based on the monitored data, achieving automated adjustment, reducing the burden of manual intervention, and improving the system's adaptability and intelligence. Furthermore, the alarm module, working in conjunction with the scoring module, enables real-time monitoring and anomaly warnings of the cement screening machine's status. The communication module promptly transmits abnormal situations to relevant personnel, enabling them to take swift action to prevent potential problems and ensure production continuity. Finally, the scoring module can not only adjust the operating score but also correct it in real time based on factors such as vibration and wear. This dynamic adjustment helps to more accurately reflect the equipment's status and promptly correct potential problems. Furthermore, by monitoring multiple aspects such as discharge flow rate, particle diameter, screen vibration, and wear, the equipment status can be detected in all aspects, providing comprehensive information support for fault diagnosis and maintenance.

[0099] Specifically, in some embodiments of the present invention, when the alarm module is used to determine the warning level of the cement screening machine based on the relationship between the adjusted work score of the scoring module and the preset work score, the alarm module further includes: obtaining the corrected work score Q4 of the cement screening machine from the scoring module. The alarm module is also used to preset a first preset work score T1 and a second preset work score T2 for the cement screening machine, and to preset a first preset warning level E1, a second preset warning level E2, and a third preset warning level E3, where T1 < T2, E1 < E2 < E3.

[0100] When Q4≤T1, the alarm module selects the first preset warning level E1 as the warning level for the cement screening machine.

[0101] When T1 < Q4 ≤ T2, the alarm module selects the second preset warning level E2 as the warning level for the cement screening machine.

[0102] When Q4 > T2, the alarm module selects the third preset warning level E3 as the warning level for the cement screening machine.

[0103] When the alarm module selects the i-th preset warning level E i as the warning level for the cement screening machine, i = 1, 2, 3, and determines the warning level of the cement screening machine as E i.

[0104] In summary, this invention provides a monitoring system for a cement screening machine. By incorporating a detection module and a vibration detection module, it achieves real-time monitoring of key parameters of the cement screening machine, including cement discharge flow rate, discharge cement particle diameter, screen vibration frequency, and screen surface wear. This helps to promptly detect changes and abnormalities during the operation of the cement screening machine. Secondly, through a scoring module, the system can comprehensively evaluate and adjust the working score of the cement screening machine based on the detected parameters. This allows the system to dynamically adjust the equipment performance according to actual working conditions, helping to improve the working efficiency of the screening machine and the quality of cement products. Simultaneously, by equipping an alarm module, the system determines the warning level of the cement screening machine based on the relationship between the adjusted working score and the preset working score. This allows operators to quickly understand the operating status of the equipment and take timely maintenance measures, thereby reducing the impact of potential faults on production. Finally, through a communication module, the system can send the determined warning level of the cement screening machine to relevant personnel, achieving remote monitoring and management. This improves the efficiency of information transmission, enabling production managers to understand the equipment status in real time and formulate corresponding maintenance plans and production scheduling in a timely manner.
