[0026] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0027] Figure 1 is a system block diagram of Embodiment 1 of the present invention;

[0028] Figure 2 This is a flow chart of the method of Embodiment 2 of the present invention. DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0030] Embodiment 1: Figure 1 As shown, an environmentally friendly dust removal screen feeding monitoring and control system includes a monitoring and control platform, which is communicatively connected to an operation test module, a data statistics module, a monitoring and control module and a database. The monitoring and control platform is used to receive a test parameter set generated by the operation test module and forward the test parameter set to the data statistics module. The monitoring and control platform is also used to receive a parameter control set generated by the data statistics module and forward the parameter control set to the database for storage.

[0031] The operation test module is used to test and analyze the operation parameters of the environmental dust removal screen: generate a test cycle, execute several test processes within the test cycle, obtain the dust concentration value at the entrance of the environmental dust removal screen at the beginning of the test process, and assign test analysis values ​​to the operation parameters of the test process. The test analysis values ​​are randomly selected from the preset range of operation parameter values;

[0032] The operating parameters of the environmental dust removal screen include processing air volume, cleaning pressure, air inlet resistance, etc. It should be noted that each operating parameter corresponds to a test cycle, that is, when the processing air volume is used as an operating parameter for test analysis, the set values ​​of the cleaning pressure and the air inlet resistance in the corresponding test cycle are fixed values ​​selected from the corresponding value range;

[0033] Then, the efficiency data XL and response data YX of the environmental dust removal screen during the test are obtained. The efficiency data XL is the average dust removal efficiency of the environmental dust removal screen during the test. The dust removal efficiency is an important indicator for measuring the performance of the dust collector, which indicates the ratio of the amount of dust removed by the dust collector per unit time to the amount of dust entering the dust collector. The response data YX is the average start-stop response time of the environmental dust removal screen during the test.

[0034] The execution coefficient ZX of the test process is obtained by the formula ZX=u1×XL-u2×YX, where u1 and u2 are both proportional coefficients, and u1>u2>1. The dust concentration value, test analysis value and execution coefficient ZX of the test process constitute the test parameter set of the test process. The test parameter sets of all test processes are sent to the monitoring and control platform. After assigning the test analysis value to the test process, multiple operating status parameters of the test process are collected and calculated to obtain the execution coefficient, and the test parameter set is constructed to provide data support for the data statistics process.

[0035] The data statistics module is used to perform data statistics analysis on the operating parameter test of the environmental dust removal screen: the maximum and minimum dust concentration values ​​of all test processes constitute a concentration range, the concentration range is divided into several concentration intervals, and the test process with dust concentration values ​​within the concentration interval is marked as a matching process. The execution coefficient ZX of all matching processes in the concentration interval is calculated by variance to obtain the distribution tendency value of the concentration interval, the distribution tendency threshold is obtained through the database, and the distribution tendency value is compared with the distribution tendency threshold:

[0036] If the allocation tendency value is less than the allocation tendency threshold, it is determined that the operating parameters of the concentration interval do not have an execution tendency, and the maximum and minimum test analysis values ​​in the matching process are marked as matching analysis values ​​of the concentration interval; if the allocation tendency value is greater than or equal to the allocation tendency threshold, it is determined that the operating parameters of the concentration interval have an execution tendency, and the test analysis value corresponding to the matching process with the largest execution coefficient ZX value is marked as the matching analysis value of the concentration interval;

[0037] It should be noted that whether the operating parameters of the concentration range have an execution tendency indicates the degree of influence of the values ​​of different operating parameters on the overall operating state of the environmental dust removal screen. When the operating parameters do not have an execution tendency, it means that the values ​​of different operating parameters have a small influence on the overall operating state of the environmental dust removal screen.

[0038] Therefore, when the operating parameter without execution tendency is the processing air volume, the maximum value of the processing air volume within the concentration range can be marked as the corresponding matching analysis value to improve the operating efficiency of the equipment. The operating efficiency is the overall dust removal efficiency of the entire process of a single operation of the environmentally friendly dust removal screen; and when the operating parameter without execution tendency is the air inlet resistance, the minimum value of the air inlet resistance within the concentration range can be marked as the corresponding matching analysis value to reduce the operating energy consumption of the equipment, that is, when the operating parameter of the concentration range does not have an execution tendency, its specific matching analysis value can be set according to the characteristics of the specific operating parameter.

[0039] The matching analysis values ​​of all concentration intervals constitute the parameter control set of the environmental dust removal screen, and the parameter control set is sent to the monitoring and control platform; the test process is divided into concentration intervals according to the dust concentration value, and then the execution tendency of the operating parameters of the concentration interval is analyzed according to the allocated tendency value, and the matching analysis value of the concentration interval is marked according to the analysis result, and then the operating parameters of the environmental dust removal screen are set according to the matching analysis value.

[0040] The monitoring and control module is used to perform operation control analysis on the environmentally friendly dust removal screen: generate a monitoring cycle, and before the environmentally friendly dust removal screen operates within the monitoring cycle, obtain the dust concentration value at the entrance of the environmentally friendly dust removal screen and mark it as the concentration monitoring value, call the parameter control set of the environmentally friendly dust removal screen through the database, mark the matching analysis value of the concentration range corresponding to the concentration monitoring value as the control analysis value, and set the value of the operating parameter of the environmentally friendly dust removal screen as the control analysis value; before the environmentally friendly dust removal screen operates, obtain the concentration monitoring value, and then call the matching analysis value corresponding to the concentration monitoring value in the parameter control set to adjust the various operating parameters of the environmentally friendly dust removal screen to the optimal value, so as to ensure the operating efficiency of the environmentally friendly dust removal screen and the timeliness of the stop control response.

[0041] Embodiment 2: Figure 2 As shown, the present invention also proposes an environmentally friendly dust removal screen feeding monitoring and control method, comprising the following steps:

[0042] Step 1: Test and analyze the operating parameters of the environmental dust removal screen: generate a test cycle, execute several test processes within the test cycle, obtain the dust concentration value at the entrance of the environmental dust removal screen at the beginning of the test process, and assign test analysis values ​​to the operating parameters of the test process;

[0043] Step 2: Obtain the execution coefficient ZX of the test process, and send the dust concentration values, test analysis values ​​and execution coefficient ZX of all test processes to the data statistics module through the monitoring and control platform;

[0044] Step 3: Perform statistical analysis on the operating parameter test of the environmental dust removal screen: The maximum and minimum dust concentration values ​​of all test processes constitute a concentration range, divide the concentration range into several concentration intervals, and mark the matching analysis value of each concentration interval;

[0045] Step 4: Conduct operation control analysis on the environmental dust removal screen: Generate a monitoring cycle. Within the monitoring cycle, retrieve the control analysis value before the environmental dust removal screen is operated, and set the value of the environmental dust removal screen operation parameter as the control analysis value.

[0046] When the present invention is working, a test cycle is generated, several test processes are executed within the test cycle, the dust concentration value at the entrance of the environmental dust removal screen is obtained at the beginning of the test process, and a test analysis value is assigned to the operating parameters of the test process; the execution coefficient ZX of the test process is obtained, and the dust concentration value, test analysis value and execution coefficient ZX of all test processes are sent to the data statistics module through the monitoring and control platform;

[0047] The maximum and minimum dust concentration values ​​of all test processes constitute a concentration range, which is divided into several concentration intervals, and the matching analysis value of each concentration interval is marked; a monitoring cycle is generated, and within the monitoring cycle, the control analysis value is retrieved before the environmental dust removal screen is operated, and the value of the environmental dust removal screen operation parameter is set as the control analysis value.

[0048] The above contents are merely examples and explanations of the structure of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.

[0049] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula close to the real value. The coefficients in the formula are set by technicians in this field according to the actual situation; for example: formula ZX=u1×XL-u2×YX; technicians in this field collect multiple groups of sample data and set corresponding execution coefficients for each group of sample data; substitute the set execution coefficients and the collected sample data into the formula, any two formulas constitute a set of two-variable linear equations, screen the calculated coefficients and take the average, and obtain the values ​​of u1 and u2 as 2.53 and 2.19 respectively;

[0050] The size of the coefficient is to quantify each parameter to obtain a specific value for subsequent comparison. The size of the coefficient depends on the amount of sample data and the initial setting of the corresponding execution coefficient for each set of sample data by technical personnel in this field; as long as it does not affect the proportional relationship between the parameter and the quantized value, such as the execution coefficient is proportional to the value of the efficiency data.
