step S100: performing metal detection according to a first metal acquisition device to obtain first metal detector information;

specifically, the first metal collecting device is a device for collecting metal foreign matter information in sewage, and is composed of a metal detector and a data processor, and is used for detecting and collecting the metal information to further obtain the first metal detector information, further, the first metal detector information is information obtained after metal detection is carried out on treated sewage suspended matters, wherein the sewage suspended matters can cause great influence on water quality, so that the sewage suspended matters are filtered, but metal fragments discharged by some factories can exist in the sewage, sludge or floccules during filtering, and the metal detector information collected and obtained by the first metal collecting device is analyzed to provide an information basis for analysis of collision detection.

Step S200: obtaining first filter screen material information of a first filter device;

Step S300: carrying out data transmission according to the motor control parameter of the first filtering device to obtain a first water inlet speed;

particularly, because first filter equipment is used for collecting and filtering the sewage suspended solid, through motor control parameter control first filter equipment's water inlet sewage inflow speed, and then filter through filter equipment, wherein, through obtaining the water velocity of water inlet, can further carry out the analysis to the water velocity of flowing into filter equipment to further carry out the analysis to the water velocity that contains metallic foreign matter, its metallic foreign matter that obtains gets into filter equipment's speed, consequently, motor control parameter can accurately obtain first water inlet water velocity, through the acquireing of realization information in the control parameter input system that data transmission will correspond.

Step S400: performing collision reaction detection on the first metal detector information and the first filter screen material information to obtain first collision detection information;

specifically, the collision response detection is performed according to the information of the metal detector and the corresponding information of the filter material, and the collision prediction is performed according to the collision between the metal detector and the filter material, for example, when the filter material includes a filter membrane, the foreign object made of metal material easily collides with the filter membrane, so that the filter membrane is damaged. Therefore, collision information prediction is carried out through the first metal detector information and the first filter screen material information, when the metal detector collides the filter screen, the risk of damage of the filter screen is calculated and analyzed, a prediction model is completed according to the attribute reaction condition between the metal detector information and the filter screen, further, the prediction of the collision information is based on the collision detection model to carry out collision damage prediction analysis, wherein the collision detection model is a mathematical model and can be obtained through training of multiple groups of training data, so that the model construction is completed when the data is converged, then the real-time metal detector information and the filter screen material information are input into the model to carry out collision damage prediction, the first collision detection information is further obtained, and the secondary data analysis after the collision detection information is completed on the basis of the collision detection information.

Step S500: generating a first collision evaluation result according to the first water inlet speed;

specifically, water inlet water flow speed obtained based on the first water inlet speed is obtained, metal detector information is obtained, and further the speed of a metal detector contained in water inlet water flow is obtained, and since collision acceleration can be generated when the metal detector information collides with the first filter screen, collision damage assessment is completed according to the acceleration and the metal quality of the metal detector, wherein the first collision assessment result is based on the water inlet speed of the first filter device for collision acceleration analysis, and can also be assessed according to the space structure between the water inlet and the filter screen, so that the accurate first collision assessment result is obtained, and effectiveness of early warning analysis is guaranteed.

Further, as shown in fig. 2, wherein, the metal detection is performed according to the first metal collecting device to obtain the first metal detector information, step S100 in the embodiment of the present application further includes:

step S110: obtaining first historical flotage collection information;

step S120: performing metal screening on the first historical suspended matter collected information to obtain first screening metal, wherein the first screening metal is a filtered matter of the first filtering device;

step S140: constructing a first metal identification database according to the first mark detection signal;

step S150: the first metal detector identifies the first metal detector via the first metal identification database.

Specifically, by analyzing the types and categories of suspended matters in the historical suspended matters of the first filtering device, when a sewage treatment plant treats sewage in a certain area, the discharged sewage foreign matters have high similarity according to the types of plants around the sewage treatment plant, therefore, by collecting the historical suspended matters, screening the flocculent, organic matters, gravel and other foreign matters in the historical suspended matters, screening the metals in the historical suspended matters to generate the first screened metals, detecting the screened metals one by one in the first metal collecting device, and obtaining signals for detecting reflection, a data processing unit in a root device marks the signals by character strings, wherein the characteristics of each category of metals have unique identification information, so that all the marked information is used as a metal identification database to complete the identification of the detection of the sewage metals, and further, the first metal identification database can be continuously updated by setting a certain period, so that the integrity and accuracy of information in the database are ensured, the information acquisition accuracy of the first metal acquisition device is achieved, and the information of the first metal detector is further accurately identified.

step S540: and generating the first collision evaluation result according to the first rotating speed and the first water inlet speed.

Specifically, according to the specific flow requirements of sewage treatment, the first filtering device is applied to different filtering scenes, and according to the equipment basic information of a sewage treatment plant, there is a certain difference in the structure of the first filtering device, for example, in order to increase the filtering efficiency, there are some variation characteristics in the structure of the first filtering screen, and based on the variation characteristics, when the first filtering screen structure is an annular structure, there is a first annular rotation control motor, so that data transmission of control parameters is performed according to the rotation motor to obtain the rotation speed of the first filtering screen, since the environmental filtering screen generates collision gain when metal with a certain acceleration contacts the surface of the filtering screen during the rotation process, the risk of breakage of the filtering screen is increased, and therefore, by evaluating the collision loss of the metal through the water flow speed of the water inlet and the rotation speed of the filtering screen, acceleration and stress analysis can be carried out by constructing a space rectangular coordinate system, the first collision assessment result is generated according to the calculation result, an assessment module can be increased in a targeted manner according to the real-time working condition of the filtering device, so that accurate assessment information is obtained, and the method has high applicability.

step S513: performing loss analysis on the filtering effect of the first filtering device based on the first filtering loss to obtain first filtering evaluation information;

step S514: and obtaining second early warning information according to the first filtering evaluation information.

Specifically, the first refilter index is data representing the refilter of the filter screen in a datamation manner, in particular, the structure of the filter screen is, for example, an annular structure or a structure with a filtering space, the first filter screen material information includes the size of the filtering holes, and then the reverse refilter loss of the filtered water flow passing through the filter screen is analyzed to obtain the first refilter index, further, when the water inlet speed of the filter device also causes a certain loss influence on the reverse refilter, so as to perform loss analysis on the filtering effect of the filter device according to the refilter loss, when the first refilter evaluation exceeds a preset refilter condition, it indicates that the current refilter loss is large, and affects the filtering effect of the first filter device, and further, the efficiency of image sewage treatment is improved, and therefore, when the first refilter evaluation coefficient exceeds a preset refilter condition, second warning information is obtained, the water inlet stability is guaranteed by changing the size of the filter screen or adjusting the rotating speed of the motor, and the filtering quality and the filtering efficiency are further improved through early warning.

Further, as shown in fig. 6, the generating the first collision assessment result according to the first rotation speed and the first water inlet speed further includes, in embodiment S400 of the present application:

step S410: constructing a first space coordinate system by simulating the working conditions of the first filtering device;

step S420: constructing a first objective function by taking the first rotating speed and the first water inlet speed as variable factors and the first collision speed as a response result;

step S430: obtaining a first response result of the first objective function according to the first objective function and the first space coordinate system;

step S440: and generating the first collision evaluation result according to the first response result.

Further, since it is necessary to calculate the corresponding screen impact damage, the result is outputted in response to the first impact speed as a function, where the first impact speed is the self speed of the first metal detector when contacting the first screen plane. By constructing the function response of the target function for completing the collision detection, the corresponding evaluation result is generated according to the response result corresponding to the function, the first collision evaluation result is ensured to have higher mathematical logicality and use reliability, the accuracy of the early warning mechanism is further increased, and the accuracy and the logicality of the collision analysis are further ensured.

Further, as shown in fig. 7, where the generating the first collision assessment result according to the first response result further includes:

step S441: performing collision variable analysis on the first metal detector information to obtain a first collision variable index;

step S443: taking the first constraint condition as a constraint condition of the first objective function to obtain a second response result;

step S444: and generating a second collision evaluation result according to the second response result.

In particular, the first objective function is based on the first rotation speed and the first water inlet speed as basic variable factors, and other variables which are analyzed according to the characteristics of the metal detector information, such as, when the information quality of the metal detector, the geometrical shape, the metal material and other variable indexes are used, therefore, by generating the first constraint condition by the metal detector information, further, a plurality of variable influences such as the service time of the filter screen and the cleaning time limit can be included as the second constraint condition, thereby obtaining a second response result of the second objective function, generating a second collision damage evaluation result, achieving the purpose of accurately obtaining the response result, and further, the applicability and high availability of the collision assessment information are improved, and the early warning quality and precision are further improved.
