Description

Technical Field

[0001] The invention belongs to the technical field of operation monitoring and control of sewage treatment coarse screen equipment, and relates to an operation monitoring and control system for sewage treatment coarse screen equipment. Background Art

[0002] The coarse screen equipment for sewage treatment is one of the key equipment used in the pretreatment stage of sewage treatment plants. Its main function is to remove larger solid impurities from sewage, such as plastic bags, wood blocks, paper, etc., to prevent these debris from entering the subsequent treatment links and causing blockage or damage to other equipment. With the increasing severity of global environmental problems, the improvement of environmental awareness has become an important driving force for the development of the sewage treatment industry. All sectors of society are paying more and more attention to water quality safety and environmental protection, which has prompted sewage treatment technology to develop in a more efficient and intelligent direction. Therefore, the monitoring, analysis and control system for the operation of sewage treatment coarse screen equipment is of great significance and role.

[0003] The existing monitoring, analysis and control systems for the operation of sewage treatment coarse screen equipment can basically meet the basic needs, but there are still certain shortcomings: on the one hand, the existing monitoring, analysis and control systems for the operation of sewage treatment coarse screen equipment mainly collect and analyze the operating current, voltage and water level difference of the water body before and after the equipment in real time during the operation of the coarse screen equipment, and then judge whether there are hidden faults in the operation status of the equipment. However, the existing monitoring, analysis and control systems for the operation of sewage treatment coarse screen equipment ignore detailed analysis from the position, equipment conveyor belt transmission conditions, etc., so that it is impossible to more accurately obtain the abnormalities or inefficiencies in the operation of sewage treatment coarse screen equipment, and thus it is impossible to ensure that the sewage treatment coarse screen equipment is always in the best working condition, which is not conducive to arranging maintenance and overhaul plans in advance, and it is impossible to reduce further damage caused by long-term operation of the equipment with problems.

[0004] On the other hand, the existing monitoring, analysis and control systems for the operation of sewage treatment coarse screen equipment lack monitoring and analysis of the cleaning effect of the sewage treatment coarse screen equipment and the accumulation of debris on the conveyor belt during operation. The accumulation of debris on the coarse screen will hinder the flow of water and reduce the treatment efficiency. In addition, the debris accumulated over a long period of time may cause wear or damage to the mechanical parts of the coarse screen, and even cause equipment failure, which is not conducive to extending the service life of the equipment and reducing maintenance costs. It is also impossible to ensure that the cleaning effect of the water before and after the coarse screen equipment meets the standards, and thus it is impossible to reduce the discharge of harmful substances in the sewage and reduce the degree of pollution to the environment, which is not conducive to protecting water resources and maintaining ecological balance. Summary of the invention

[0005] In view of this, in order to solve the problems raised in the above background technology, a sewage treatment coarse screen equipment operation monitoring and control system is now proposed.

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0016] Figure 1 It is a schematic diagram of system module connection of the present invention. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 As shown, the present invention provides a sewage treatment coarse screen equipment operation monitoring and control system, and the specific modules are distributed as follows: equipment operation analysis module, equipment cleaning analysis module, control terminal, equipment cleaning effect analysis module and cloud database. Among them, the connection mode between the modules is: the equipment operation analysis module and the equipment cleaning analysis module are respectively connected to the control terminal, the control terminal is connected to the equipment cleaning effect analysis module, the equipment cleaning effect analysis module is respectively connected to the equipment operation analysis module and the equipment cleaning analysis module, and the cloud database is respectively connected to the equipment operation analysis module, the equipment cleaning analysis module and the equipment cleaning effect analysis module.

[0019] The equipment operation analysis module is used to record the sewage treatment coarse screen equipment that needs to be monitored as each designated sewage treatment coarse screen equipment, and then monitor it in real time, obtain the operation data of each designated sewage treatment coarse screen equipment, analyze the operation feedback indicators of each designated sewage treatment coarse screen equipment, judge the operation control requirements of each designated sewage treatment coarse screen equipment, and then obtain the operation control requirements of each sewage treatment coarse screen equipment.

[0020] As a preferred feasibility example, the operation data of each designated sewage treatment coarse screen equipment includes position compliance, transmission speed, transmission smoothness, water level difference and water flow.

[0021] It should be further explained that the reasons for using position compliance, transmission speed, transmission smoothness, water level difference and water flow as the operating data of each designated sewage treatment coarse screen equipment are: (1) Position compliance refers to the degree of match between the conveyor belt position and the standard position when the coarse screen is in operation. In the sewage treatment system, the conveyor belt position of the coarse screen is crucial to the pretreatment effect of the sewage. Reasonable conveyor belt position can ensure that the sewage is fully intercepted and filtered before entering the subsequent treatment unit, thereby improving the efficiency of the entire treatment system. Therefore, monitoring position compliance is one of the important indicators for evaluating the operating status of the coarse screen equipment.

[0022] (2) The transmission speed is a key parameter in the operation of the coarse screen equipment, which directly affects the filtration effect of sewage and the processing capacity of the equipment. Too fast a transmission speed may lead to poor interception effect, so that some solid matter cannot be effectively intercepted and enter the subsequent treatment unit, while too slow a transmission speed may cause equipment overload, increase equipment wear and energy consumption. Therefore, controlling the transmission speed within a reasonable range is the key to ensure the efficient and stable operation of the coarse screen equipment.

[0023] (3) Transmission smoothness reflects the operating status of the transmission system of the coarse screen equipment. Smooth transmission can ensure the smooth operation of the equipment and reduce the occurrence of failures. If the transmission is not smooth, it may cause problems such as equipment jamming and abnormal noise, and even cause equipment damage in serious cases. Therefore, monitoring transmission smoothness is of great significance for timely detection and resolution of equipment problems.

[0024] (4) Water level difference is an important parameter that reflects the interception effect of the coarse screen. In the sewage treatment process, the coarse screen reduces the suspended solids content in the sewage by intercepting the solid matter in the sewage. When the sewage passes through the coarse screen, due to the interception effect of the solid matter, a certain water level difference will be formed before and after the screen. Monitoring the water level difference can understand whether the interception effect of the screen meets the standard and adjust the operating status of the equipment accordingly.

[0025] (5) Water flow is one of the basic parameters in the sewage treatment process, which directly affects the operating efficiency and processing capacity of the entire treatment system. For coarse screen equipment, the size of the water flow determines the amount of sewage and solid matter content that the equipment needs to treat. Therefore, monitoring the water flow can help understand whether the equipment's processing capacity meets actual needs, and optimize equipment configuration and operation scheduling accordingly.

[0026] It needs to be further explained that the specific method of obtaining the position conformity, transmission speed, transmission smoothness, water level difference and water flow of each designated sewage treatment coarse screen equipment is: use the deployed high-definition camera to shoot each designated sewage treatment coarse screen equipment to obtain a high-definition image of each designated sewage treatment coarse screen equipment, and use image processing technology to analyze the conveyor belt position in the high-definition image of each designated sewage treatment coarse screen equipment, and compare it with the standard position of the conveyor belt in the standard image of each designated sewage treatment coarse screen equipment stored in the cloud database to obtain the overlap between the conveyor belt position in the high-definition image of each designated sewage treatment coarse screen equipment and the standard position of the conveyor belt in the corresponding standard image, which is recorded as the position conformity of each designated sewage treatment coarse screen equipment.

[0027] The transmission speed of each designated sewage treatment coarse screen equipment is directly measured by using the arranged speed sensors.

[0028] The vibration sensors are used to directly detect the vibration amplitudes of each designated sewage treatment coarse screen equipment. ,in , The serial number of each designated sewage treatment coarse screen equipment, To specify the number of sewage treatment coarse screen equipment, , is the number of each vibration, The vibration frequency is obtained by using the arranged current sensor to detect the transmission machine of each designated sewage treatment coarse screen equipment to obtain the detection current of each transmission machine of each designated sewage treatment coarse screen equipment. ,in , is the number of each test, Analyze the transmission smoothness of each designated sewage treatment coarse screen equipment for the number of tests ,in For the The maximum vibration amplitude of a specified sewage treatment coarse screen equipment, is the set allowable current difference.

[0029] The water level heights of the water bodies in front of and behind each designated sewage treatment coarse screen device are directly measured using liquid level sensors arranged in the water bodies in front of and behind each designated sewage treatment coarse screen device. The water level heights of the water bodies in front of and behind each designated sewage treatment coarse screen device are further subtracted from the water level heights of the water bodies behind them. The difference is recorded as the water level difference of each designated sewage treatment coarse screen device.

[0030] The water flow of each designated sewage treatment coarse screen equipment is directly measured using the deployed flow meters.

[0031] As a preferred feasibility example, the operation feedback indicators of each designated sewage treatment coarse screen equipment are specifically analyzed in the following manner: extracting the position conformity, transmission speed and transmission smoothness of each designated sewage treatment coarse screen equipment, which are recorded as ,in , The serial number of each designated sewage treatment coarse screen equipment, Analyze the mechanical evaluation index corresponding to the operation feedback index of each designated sewage treatment coarse screen equipment for the specified number of sewage treatment coarse screen equipment ,in are the position compliance threshold and transmission smoothness threshold of the sewage treatment coarse screen equipment extracted from the cloud database, Extracted from the cloud database The standard transmission speed of a specified sewage treatment coarse screen equipment, It is the permissible difference between the set transmission speed and the standard transmission speed.

[0032] It should be further explained that the permissible difference between the set transmission speed and the standard transmission speed may be 0.01 m / s, which means that a deviation of one percent is allowed between the transmission speed and the standard transmission speed.

[0033] Extract the water level difference and water flow rate of each designated sewage treatment coarse screen equipment and record them as , analyze the corresponding water flow evaluation index of the operation feedback indicators of each designated sewage treatment coarse screen equipment ,in are the standard water level difference and standard water flow of the sewage treatment coarse screen equipment extracted from the cloud database, They are the allowable difference between the set water level difference and the standard water level difference, and the allowable difference between the water flow rate and the standard water flow rate.

[0034] It should be further explained that the allowable difference between the set water level difference and the standard water level difference and the allowable difference between the water flow rate and the standard water flow rate can be set to 0.01 meters and 0.01 cubic meters per second respectively, which means that a deviation of one percent is allowed between the water level difference and the standard water level difference and between the water flow rate and the standard water flow rate.

[0035] Analyze the operational feedback indicators of each designated sewage treatment coarse screen equipment ,in They are the weight coefficients of the mechanical evaluation index corresponding to the set operating indicators and the water flow evaluation index corresponding to the set operating indicators.

[0036] It should be further explained that the weight coefficients of the mechanical evaluation index corresponding to the set operating index and the water flow evaluation index corresponding to the set operating index are set to 0.55 and 0.45 respectively.

[0037] The mechanical evaluation index focuses on the mechanical performance, operating status and stability of sewage treatment coarse screen equipment. The stable operation of these equipment is the key to ensure the continuous operation of the entire sewage treatment system. Therefore, the mechanical evaluation index is given a higher weight coefficient of 0.55, which can better reflect the importance of the equipment in the sewage treatment process. Through regular evaluation and monitoring of mechanical performance, potential equipment failures can be discovered and resolved in a timely manner, maintenance costs and downtime can be reduced, and overall operational efficiency can be improved. Therefore, a higher weight coefficient helps to strengthen the importance of equipment maintenance management.

[0038] The water flow assessment index focuses on the flow state, water quality changes and treatment effects of sewage during treatment. These indicators directly reflect the treatment capacity and effluent quality of the sewage treatment system. Giving the water flow assessment index an appropriate weight coefficient of 0.45 can ensure that the importance of water quality treatment effects is fully considered during the assessment process. By analyzing the water flow assessment index, we can understand the flow characteristics and change laws of sewage during treatment, providing a basis for system optimization and adjustment.

[0039] As a preferred feasibility example, the specific judgment method of the operation control requirements of each designated sewage treatment coarse screen equipment includes: subtracting the operation feedback index of each designated sewage treatment coarse screen equipment from the preset operation feedback index threshold value, and obtaining the difference between the operation feedback index of each designated sewage treatment coarse screen equipment and the operation feedback index threshold value; if the difference between the operation feedback index of a designated sewage treatment coarse screen equipment and the operation feedback index threshold value is less than 0, then the operation control requirement of the designated sewage treatment coarse screen equipment is recorded as the operation control requirement required, and the designated sewage treatment coarse screen equipment is recorded as the operation control sewage treatment coarse screen equipment.

[0040] Then the operation control of each sewage treatment coarse screen equipment is obtained.

[0041] The control terminal is used to control each operation control sewage treatment coarse screen equipment and each cleaning control sewage treatment coarse screen equipment.

[0042] As a preferred feasibility example, the specific operation of controlling each operation-controlled sewage treatment coarse screen device includes: filtering the operation data of each operation-controlled sewage treatment coarse screen device from the operation data of each designated sewage treatment coarse screen device to obtain the operation data of each operation-controlled sewage treatment coarse screen device.

[0043] The indicator lights of each component of each operation and control sewage treatment coarse screen equipment are extracted from the cloud database. Combined with the operation data of each operation and control sewage treatment coarse screen equipment, the operation failure causes of each operation and control sewage treatment coarse screen equipment are analyzed, and then corresponding feedback and operation control are carried out.

[0044] A specific example, the component indicator lights of the component indicator lights that control the operation of the sewage treatment coarse screen equipment include but are not limited to a drive motor overload indicator light, a tooth rake control motor overload indicator light, a cable break indicator light, a steel rope break indicator light, and a tooth rake not reaching the bottom indicator light.

[0045] The operation data of each operation control sewage treatment coarse screen equipment include position compliance, transmission speed, transmission smoothness, water level difference and water flow.

[0046] It needs to be further explained that the specific content of analyzing the causes of operating failures of each operating and controlling sewage treatment coarse screen equipment includes: extracting the indicator lights of each component of each operating and controlling sewage treatment coarse screen equipment. If the indicator light of a component of a certain operating and controlling sewage treatment coarse screen equipment is red, and the operating data of the operating and controlling sewage treatment coarse screen equipment meet the requirements, it means that the cause of the operating failure of the operating and controlling sewage treatment coarse screen equipment is the operating failure of a component, which is then fed back and further inspected and processed by professionals.

[0047] If the indicator lights of the components of a certain operation control sewage treatment coarse screen equipment are all green, and there is an item in the operation data of the operation control sewage treatment coarse screen equipment that does not meet the requirements, it means that the operation failure of the operation control sewage treatment coarse screen equipment is caused by the operation data failure, which will then be fed back and operated.

[0048] The present invention analyzes the operation feedback indicators of each designated sewage treatment coarse screen equipment and obtains each operation control sewage treatment coarse screen equipment, which helps to promptly discover and solve abnormal or inefficiency problems in the operation of sewage treatment coarse screen equipment, ensures that the sewage treatment coarse screen equipment is always in the best working state, thereby improving the overall sewage treatment efficiency, and is also conducive to arranging maintenance and overhaul plans in advance, reducing further damage caused by long-term operation of equipment with problems.

[0049] The equipment cleaning analysis module is used to obtain the cleaning data of each designated sewage treatment coarse screen equipment, analyze the cleaning feedback indicators of each designated sewage treatment coarse screen equipment, determine the cleaning control requirements of each designated sewage treatment coarse screen equipment, and then obtain the cleaning control of each sewage treatment coarse screen equipment.

[0050] As a preferred feasibility example, the cleaning data of each designated sewage treatment coarse screen device includes the degree of debris accumulation, the number of debris types and the name of each debris type.

[0051] It is necessary to further explain that the reasons for using the degree of debris accumulation, the number of debris types and the names of each debris type as the cleaning data for each designated sewage treatment coarse screen equipment are: (1) The degree of debris accumulation directly reflects the operating efficiency and filtration effect of the coarse screen. Excessive accumulation indicates that the screen may be close to or exceed its processing capacity and needs to be cleaned in time to restore its normal operation. Regular monitoring of the degree of debris accumulation can help prevent screen blockage and avoid subsequent treatment equipment failure or shutdown due to blockage.

[0052] (2) The number of debris types reflects the complexity and characteristics of sewage. Different types of debris may have different effects on the screen and subsequent treatment equipment, so understanding their types helps to develop targeted treatment plans. By counting the number of debris types, these problems can be discovered and dealt with in a timely manner. Changes in the number of debris types can also be used as an indicator to evaluate the effectiveness of sewage treatment. If the amount of a certain type of debris is significantly reduced, it may mean that the effectiveness of the treatment process has been improved.

[0053] (3) Knowing the specific names of debris types helps to carry out precise cleaning work. Different types of debris may require different cleaning methods and tools. Knowing the names of debris types helps to analyze the sources of these debris and take measures to reduce the chance of them entering the sewage treatment system. For common types of debris, the design of the grille can be improved to improve its filtering effect and anti-clogging ability. For example, for debris that is easy to entangle, the shape and spacing of the grille bars can be optimized.

[0054] It should be further explained that the specific method for obtaining the degree of debris accumulation, the number of debris types and the names of each type of debris of each designated sewage treatment coarse screen equipment is: using the deployed high-definition camera to shoot each designated sewage treatment coarse screen equipment to obtain a high-definition image of each designated sewage treatment coarse screen equipment, and further using image analysis technology to analyze and obtain the debris coverage area in the high-definition image of each designated sewage treatment coarse screen equipment ,in , The serial number of each designated sewage treatment coarse screen equipment, The number of designated sewage treatment coarse screen equipment is measured by using the deployed pressure sensors to directly measure the debris weight of each designated sewage treatment coarse screen equipment. . Analyze the degree of debris accumulation in each designated sewage treatment coarse screen equipment ,in They are respectively the correction value corresponding to the unit debris coverage area and the correction value corresponding to the unit debris weight.

[0055] Image analysis technology is further used to analyze the high-definition images of each designated sewage treatment coarse screen equipment to obtain the types of debris in the high-definition images of each designated sewage treatment coarse screen equipment, and statistics are performed to obtain the number of debris types in the high-definition images of each designated sewage treatment coarse screen equipment, which is recorded as the number of debris types for each designated sewage treatment coarse screen equipment.

[0056] The pictures corresponding to each type of debris in the high-definition image of each designated sewage treatment coarse screen equipment are matched with the pictures corresponding to each reference debris type name stored in the cloud database to obtain the names of each type of debris for each designated sewage treatment coarse screen equipment.

[0057] As a preferred feasibility example, the cleaning feedback index of each designated sewage treatment coarse screen equipment, its specific analysis method includes: extracting the name of each debris type of each designated sewage treatment coarse screen equipment, matching it with the cleaning feedback corresponding impact index corresponding to each reference debris type name stored in the cloud database, and obtaining the cleaning feedback corresponding impact index corresponding to each debris type name of each designated sewage treatment coarse screen equipment. ,in , is the number of each type of sundries. The number of names of miscellaneous items.

[0058] The debris accumulation degree and the number of debris types of each designated sewage treatment coarse screen equipment are extracted and recorded as , analyze the cleaning feedback indicators of each designated sewage treatment coarse screen equipment ,in is the debris accumulation level threshold of the sewage treatment coarse screen equipment extracted from the cloud database.

[0059] As a preferred feasibility example, the specific judgment method of the cleaning control demand of each designated sewage treatment coarse screen equipment includes: comparing the cleaning feedback index of each designated sewage treatment coarse screen equipment with the preset cleaning feedback index threshold; if the cleaning feedback index of a designated sewage treatment coarse screen equipment is less than the cleaning feedback index threshold, then the cleaning control demand of the designated sewage treatment coarse screen equipment is recorded as a cleaning control demand, and the designated sewage treatment coarse screen equipment is recorded as a cleaning control sewage treatment coarse screen equipment; otherwise, the cleaning control demand of the designated sewage treatment coarse screen equipment is recorded as no cleaning control demand is required.

[0060] Then, various clean and controlled sewage treatment coarse screen equipments are obtained.

[0061] As a preferred feasibility example, the specific operation of controlling each clean and controlled sewage treatment coarse screen device includes: extracting the names of various types of debris from each designated sewage treatment coarse screen device, screening out the names of various types of debris from each clean and controlled sewage treatment coarse screen device, and further performing corresponding cleaning control on each clean and controlled sewage treatment coarse screen device according to the cleaning control method of each type of debris.

[0062] The present invention analyzes the cleaning feedback index of each designated sewage treatment coarse screen equipment and obtains each cleaning control sewage treatment coarse screen equipment, which helps to timely discover and remove debris on the sewage treatment coarse screen equipment, ensures smooth water flow, thereby improving the treatment efficiency of the entire sewage treatment system, and is also beneficial to reduce the impact and wear of debris on the sewage treatment coarse screen equipment, which is beneficial to extend the service life of the equipment and reduce maintenance costs.

[0063] The equipment cleaning effect analysis module is used to obtain the water cleaning data before and after each designated sewage treatment coarse screen equipment, analyze the water cleaning effect before and after each designated sewage treatment coarse screen equipment, and obtain each sewage treatment coarse screen equipment with unqualified cleaning effect, further analyze the reasons for the unqualified sewage treatment coarse screen equipment with unqualified cleaning effect, and provide feedback;

[0064] As a preferred feasibility example, the water cleaning data before and after each designated sewage treatment coarse screen device includes the amount of suspended solids and turbidity of the water before and after.

[0065] It should be further explained that the reason for using the suspended solids and turbidity of the water body before and after the coarse screen as the clean water body data before and after each designated sewage treatment coarse screen equipment is: (1) The suspended solids amount is an important indicator to measure the content of insoluble solid particles in the water body. By comparing the suspended solids amount of the water body before and after the coarse screen, the interception effect of the coarse screen on the suspended solids in the sewage can be intuitively evaluated. If the difference in the amount of suspended solids before and after is significant, it means that the coarse screen has a better filtering effect. Otherwise, it may be necessary to check the operating status of the screen or perform necessary maintenance.

[0066] (2) Turbidity is a physical quantity that reflects the clarity of water and is closely related to the content of suspended matter, colloids, etc. in the water. By measuring the turbidity of the water before and after the coarse screen, the filtration effect of the screen can be further verified. The reduction in turbidity means that the water becomes clearer, which indirectly shows that the coarse screen removes impurities in the sewage.

[0067] It needs to be further explained that the specific method for obtaining the suspended solids content and turbidity of the water bodies before and after each designated sewage treatment coarse screen device is: a certain volume of representative water samples are collected from the water bodies before and after each designated sewage treatment coarse screen device, and recorded as the samples of the water bodies before and after each designated sewage treatment coarse screen device, respectively; the samples of the water bodies before and after each designated sewage treatment coarse screen device are further filtered using a filter membrane of known weight to obtain the filter membrane after filtering the samples of the water bodies before and after each designated sewage treatment coarse screen device, and the filter membrane is placed in an oven to dry to constant weight, and then the weight of the filter membrane after filtering the samples of the water bodies before and after each designated sewage treatment coarse screen device is weighed with a balance. , according to the analytical formula and Get the amount of suspended solids in the water before and after each designated sewage treatment coarse screen equipment ,in is the weight of the filter membrane, The volume of the water sample before and after each designated sewage treatment coarse screen equipment.

[0068] The turbidity of the water before and after each designated sewage treatment coarse screen equipment is directly measured using a turbidity meter.

[0069] As a preferred feasibility example, the specific analysis method of the cleaning effect of the water body before and after each designated sewage treatment coarse screen equipment includes: extracting the suspended solids and turbidity of the water body before and after each designated sewage treatment coarse screen equipment, respectively recorded as , analyze the evaluation coefficient of water cleaning effect before and after each designated sewage treatment coarse screen equipment ,in They are the standard deviation of suspended solids and turbidity in the water before and after the sewage treatment coarse screen equipment extracted from the cloud database. , Is a non-symbol.

[0070] It needs to be further explained that It indicates that the suspended solids and turbidity of the water bodies before and after each designated sewage treatment coarse screen equipment are within the allowable deviation.

[0071] The front and rear water cleaning effect evaluation coefficients of each designated sewage treatment coarse screen equipment are compared with the preset front and rear water cleaning effect evaluation coefficient thresholds, and the designated sewage treatment coarse screen equipment whose front and rear water cleaning effect evaluation coefficients are less than the front and rear water cleaning effect evaluation coefficient thresholds are screened out and recorded as sewage treatment coarse screen equipment with unqualified cleaning effects.

[0072] As a preferred feasibility example, the specific analysis method of the reasons for the failure of each sewage treatment coarse screen device with unqualified cleaning effect includes: extracting the number of each operation control sewage treatment coarse screen device and the number of each cleaning control sewage treatment coarse screen device.

[0073] The numbers of each sewage treatment coarse screen equipment with unqualified cleaning effect are matched with the numbers of each operation control sewage treatment coarse screen equipment and the numbers of each cleaning control sewage treatment coarse screen equipment respectively. If the number of a sewage treatment coarse screen equipment with unqualified cleaning effect is successfully matched with the number of an operation control sewage treatment coarse screen equipment or the number of a cleaning control sewage treatment coarse screen equipment, the failure reason of the sewage treatment coarse screen equipment with unqualified cleaning effect is recorded as equipment operation failure or equipment cleaning failure.

[0074] If the number of a sewage treatment coarse screen equipment with unqualified cleaning effect successfully matches the number of a sewage treatment coarse screen equipment with operation control and the number of a sewage treatment coarse screen equipment with cleaning control, the failure reason of the sewage treatment coarse screen equipment with unqualified cleaning effect will be recorded as equipment operation failure and equipment cleaning failure.

[0075] If the number of a sewage treatment coarse screen device with unqualified cleaning effect fails to match the number of a certain operation control sewage treatment coarse screen device or the number of a certain cleaning control sewage treatment coarse screen device, the failure cause of the sewage treatment coarse screen device with unqualified cleaning effect shall be recorded as other faults.

[0076] The cloud database is used to store the position compliance threshold, transmission smoothness threshold, standard water level difference, standard water flow rate and debris accumulation threshold of the sewage treatment coarse screen equipment, store the standard transmission speed of each specified sewage treatment coarse screen equipment, store the standard deviation value of the suspended solids and the standard deviation value of the turbidity of the water body before and after the sewage treatment coarse screen equipment, and store the cleaning feedback corresponding to each reference debris type name. The corresponding impact index.

[0077] The present invention analyzes the cleaning effects of the front and rear water bodies of each designated sewage treatment coarse screen equipment, obtains each sewage treatment coarse screen equipment with unqualified cleaning effects and analyzes the reasons for the unqualified cleaning effects, which is conducive to intuitively evaluating the cleaning effects of the coarse screen equipment, and performing targeted equipment maintenance and adjustments on the equipment with unqualified cleaning effects, ensuring that the cleaning effects of the front and rear water bodies of the coarse screen equipment meet the standards, reducing the discharge of harmful substances in sewage, reducing the degree of pollution to the environment, and also helping to optimize the operating status of the sewage treatment coarse screen equipment and reduce the occurrence rate of failures.
