Detailed Description
The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, based on the embodiments in this disclosure are intended to be within the scope of this disclosure.
The embodiment of the disclosure provides a control method of a garbage incinerator, as shown in fig. 1, the method for identifying sound effects in a vehicle comprises the following steps:
Step 101, obtaining a reference parameter and a first parameter.
The reference parameter is used for indicating the optimal incineration effect of the garbage incinerator in the historical period, and the first parameter is used for indicating the current incineration effect of the garbage incinerator.
In the method, the incineration effect of the garbage incinerator is quantified in a numerical form, so that the incineration effect of the garbage incinerator is conveniently monitored, and further follow-up variable regulation and control are guided.
In an example, a trained target model may be applied to analyze properties (such as quality, composition, color, output rate, etc.) of tail end products (such as flue gas, ash, etc.) of the garbage incinerator, so as to obtain parameters indicating the incineration effect of the garbage incinerator.
In the above example, the initial network model (such as DNN, CNN, LSTM, resNet) may be iteratively trained by using a preset plurality of sets of training data, until the iteration is finished, a model obtained by training is determined to be the target model, where the output of the last but one layer of the target model may be used as a parameter indicating the incineration effect of the garbage incinerator, and one set of training data includes first sub-data and second sub-data derived from the same garbage incinerator, where the incineration effect corresponding to the first sub-data is better than the incineration effect corresponding to the second sub-data, the first sub-data is an attribute of a tail end product of the garbage incinerator in a first period, the second sub-data is an attribute of a tail end product of the garbage incinerator in a second period, the first moment and the second period are different periods, and the target model is used to determine attribute data corresponding to a better incineration effect in two attribute data (i.e., an attribute of the tail end product of the garbage incinerator).
The larger the parameter value output by the target model, the better the incineration effect of the garbage incinerator is illustrated by the example.
And 102, determining the difference between the reference parameter and the first parameter as a first target deviation when the incineration effect indicated by the reference parameter is better than the incineration effect indicated by the first parameter.
The implementation process of step 102 specifically includes:
Calculating a difference between the reference parameter and the first parameter when the reference parameter is greater than the first parameter;
Skipping a subsequent action when the difference between the reference parameter and the first parameter is less than or equal to a preset deviation threshold; and determining the difference between the reference parameter and the first parameter as a first target deviation when the difference between the reference parameter and the first parameter is greater than a preset deviation threshold.
The condition that the difference between the reference parameter and the first parameter is smaller than or equal to the preset deviation threshold value can be understood that the current incineration effect of the garbage incinerator can be approximately considered to reach the historical optimal level.
And 103, regulating and controlling a plurality of control variables of the garbage incinerator according to the first target deviation.
The plurality of control variables comprise air chamber flow, main steam flow, oxygen content and garbage feeding amount of the garbage incinerator; the incineration effect of the regulated garbage incinerator is better than the incineration effect indicated by the first parameter.
In the embodiment of the disclosure, the current incineration effect of the garbage incinerator is evaluated by taking the optimal incineration effect of the garbage incinerator in the historical period as a reference, and when the current incineration effect is lower than the historical optimal incineration effect, a plurality of control variables of the garbage incinerator are regulated and controlled based on the deviation of the current incineration effect and the historical optimal incineration effect, so that the incineration effect of the garbage incinerator is optimized.
Wherein, the regulation and control of a plurality of control variables of the garbage incinerator can be as follows: at least one of increasing or decreasing the flow rate of the air chamber, increasing or decreasing the flow rate of the main steam, increasing or decreasing the oxygen content, and increasing or decreasing the feed rate of the waste.
In the disclosure, each control variable is provided with a corresponding regulation and control direction, if the current incineration effect of the garbage incinerator is poor after the variable is regulated based on the regulation and control direction corresponding to a certain control variable, the regulation and control direction of the control variable is reversed, and the variable is regulated again based on the reversed regulation and control direction.
For example, if the air chamber flow rate of the garbage incinerator is increased according to the first target deviation (the adjustment direction of the air chamber flow rate is increased at this time), and then the combustion effect of the garbage incinerator after the adjustment is monitored to be poor, the adjustment direction of the air chamber flow rate is reversed, the adjustment direction of the air chamber flow rate is reduced at this time, and the combustion effect of the garbage incinerator is optimized by reducing the air chamber flow rate.
In one embodiment, the adjusting the plurality of control variables of the garbage incinerator according to the first target deviation includes:
Acquiring a plurality of continuous deviation intervals, wherein the deviation intervals correspond to the control variables one by one, each deviation interval is determined according to the influence degree of the corresponding control variable on the incineration effect of the garbage incinerator, and the larger the influence degree is, the larger the interval minimum value of the corresponding deviation interval is;
Determining a first target variable in the plurality of control variables according to the first target deviation, wherein the first target deviation is located in a deviation interval corresponding to the first target variable;
and regulating and controlling the first target variable according to the first target deviation.
For example, if the plurality of control variables include a first control variable, a second control variable, and a third control variable, and the degrees of influence of the first control variable, the second control variable, and the third control variable on the incineration effect of the garbage incinerator decrease sequentially, the three continuous deviation intervals corresponding to the first control variable, the second control variable, and the third control variable may be: [50, 30], (30, 15], (15, 5], wherein 30 is a section minimum value of a deviation section corresponding to the first control variable, 15 is a section minimum value of a deviation section corresponding to the second control variable, and 5 is a section minimum value of a deviation section corresponding to the third control variable.
The reaction process of the garbage incinerator is a nonlinear, multivariable coupling, time-varying and large-time-lag industrial process, the reaction mechanism is complex and the influence factors are numerous, so that if a plurality of control variables in the garbage incinerator are regulated and controlled at the same time, the interaction among the plurality of control variables can cause great fluctuation of regulation and control effects, and further deviate from an expected regulation and control target, and the regulation and control effects brought by regulation and control means have hysteresis, so that after the regulation and control in the current stage fail, the condition can be discovered and remedied at least until the next stage, but due to the instability of the regulation and control effects, the garbage incinerator is in a state of repeated fluctuation, the incineration effect of the garbage incinerator is seriously reduced, and based on the influence degree of the plurality of control variables on the incineration effect of the garbage incinerator, a plurality of continuous deviation intervals are formed; after the first target deviation is calculated, the control variable corresponding to the deviation interval in which the first target deviation falls is determined to be the first target variable, and the first target variable is independently regulated and controlled, so that the problem of repeated fluctuation caused by simultaneous regulation and control of multiple control variables can be avoided, the regulation and control times of the garbage incinerator can be shortened as much as possible, and the time consumption of the current incineration effect of the garbage incinerator to reach the historical optimal incineration effect is shortened.
In one embodiment, the adjusting the first target variable according to the first target deviation includes:
regulating and controlling the first target variable according to the first target deviation and a first regulating rate;
Acquiring a second parameter, wherein the second parameter is the incineration effect of the garbage incinerator after the first target variable is regulated and controlled according to the first regulation rate;
Determining a difference between the reference parameter and the second parameter as a second target deviation when the incineration effect indicated by the reference parameter is better than the incineration effect indicated by the second parameter;
And under the condition that the second target deviation is positioned in a deviation interval corresponding to the first target variable, regulating and controlling the first target variable according to a second regulating rate according to the second target deviation, wherein the second regulating rate is smaller than the first regulating rate.
It should be understood that this embodiment is directed to the case where the regulation direction of the first target variable is correct but the regulation amplitude is insufficient, that is, the incineration effect indicated by the second parameter is better than the incineration effect indicated by the first parameter.
In this embodiment, if the first target variable is adjusted once, the incineration effect of the garbage incinerator is improved but the history is not optimal, and when the adjusted deviation result indicates that the first target variable is still adjusted, the incineration effect of the garbage incinerator is continuously approaching to the history to be optimal in an iterative adjustment manner by adjusting the first target variable again, so as to gradually reduce the fluctuation range of the in-furnace reaction of the garbage incinerator in the adjustment stage, and improve the overall incineration effect of the garbage incinerator.
In one example, the first target variable may be further configured to be adjusted according to the first target deviation at a first adjustment rate and a first adjustment magnitude, and the first target variable may be adjusted according to the second target deviation at a second adjustment rate and a second adjustment magnitude, wherein the first adjustment magnitude is less than the second adjustment magnitude;
In this case, when the same control variable is adjusted a plurality of times, it is considered that the adjustment range of the control variable in the previous adjustment is lower, and the adjustment range of the last adjustment is set to be larger than the adjustment range of the previous adjustment, so that the adjustment frequency of the control variable can be shortened, and the adjustment rate of the last adjustment is set to be smaller than the adjustment rate of the previous adjustment.
In one embodiment, after said determining the difference between the reference parameter and the second parameter as the second target deviation, the method further comprises:
determining a second target variable in the plurality of deviation intervals when the second target deviation is not in the deviation interval corresponding to the first target variable, wherein the second target deviation is located in the deviation interval corresponding to the second target variable;
And regulating and controlling the second target variable according to the second target deviation, wherein the influence degree of the second target variable on the incineration effect of the garbage incinerator is lower than that of the first target variable.
Through the arrangement, the selective adjustment of each control variable of the garbage incinerator is realized, and after one or more adjustments are carried out based on the control variable with larger influence degree, if the incineration effect of the garbage incinerator approaches to the optimal history, the current adjustment of each control variable of the garbage incinerator is ended; otherwise, the control variables with smaller influence degree are continuously adjusted correspondingly until the incineration effect of the garbage incinerator approaches to the optimal history.
The step-type adjustment device can not only shorten the time consumption of the garbage incinerator for approaching the optimal incineration effect to the history, but also effectively reduce the fluctuation range of the garbage incinerator for reaction in the adjustment stage, and can avoid the problem of repeated fluctuation caused by simultaneous adjustment and control of multiple control variables by only adjusting one control variable at a time.
In one embodiment, the adjustment rate corresponding to the second target variable is less than the adjustment rate corresponding to the first target variable.
The first target variable may be understood as any one of the plurality of control variables, and the second target variable may be understood as any one of the plurality of control variables having a lower degree of influence on the incineration effect of the garbage incinerator than the first target variable.
In the embodiment, the adjustment rate corresponding to the second target variable is set to be smaller than the adjustment rate corresponding to the first target variable, so that the adjustment rate of the corresponding control variable is reduced in an intermediate and later stage of adjustment of the garbage incinerator, and the fluctuation range of the in-furnace reaction of the garbage incinerator in the adjustment stage is further reduced.
In this case, since each control variable can take a plurality of adjustment rates during the adjustment phase, the adjustment rate corresponding to the second target variable is smaller than the adjustment rate corresponding to the first target variable is understood as: the maximum rate of the second target variable in the plurality of adjustment rates corresponding to the adjustment stage is smaller than the minimum rate of the first target variable in the plurality of adjustment rates corresponding to the adjustment stage.
In one embodiment, the incineration effect is determined according to at least one of the following:
The blackness of the flue gas discharged from the tail end of the garbage incinerator;
the content of target components in the flue gas exhausted from the tail end of the garbage incinerator indicates that the garbage incinerator has incomplete combustion;
The tail end of the garbage incinerator discharges ash in unit time;
wherein, the greater the blackness of the flue gas, the poorer the incineration effect; the larger the content of the target component is, the worse the incineration effect is; the larger the ash discharge amount is, the poorer the incineration effect is.
In this embodiment, the incineration effect of the garbage incinerator is comprehensively determined based on three indexes of the blackness of the flue gas exhausted from the tail end of the garbage incinerator, the content of the target component in the flue gas exhausted from the tail end of the garbage incinerator, and the ash exhaust amount of the tail end in unit time, so that the determined parameters (such as the reference parameter, the first parameter, the second parameter, and the like) can be more accurate.
Wherein, the flue gas blackness can be understood as ringeman blackness; the target components are components that are not generated when the garbage incinerator is completely combusted, but are generated only when the garbage incinerator is not completely combusted, for example: dioxins, carbon monoxide, and the like.
Illustratively, the unit time may be one minute, 10 minutes, or the like.
In one embodiment, the reference parameter is updated based on the first parameter when the incineration effect indicated by the first parameter is better than the incineration effect indicated by the reference parameter.
In the embodiment, under the condition that the current incineration effect of the garbage incinerator is better than the history optimum, the current incineration effect of the garbage incinerator is updated to the history optimum so as to dynamically update the reference parameters, and further adapt to the condition that the incineration effect of the garbage incinerator is continuously optimized in actual production, so that the application of the method is more flexible.
Wherein the reference parameter is updated based on the first parameter, and the first parameter is used as the new reference parameter.
