Description

Technical Field

[0001] The present invention relates to the technical field of smart cities based on the Internet, and in particular to a pressure regulating method for a domestic waste dehydration device of a smart city based on the Internet. Background Art

[0002] As the amount of domestic waste in cities increases, it needs to be disposed of in a timely manner. At present, the main methods of treating domestic waste are: first, sanitary landfill; second, transporting domestic waste to incineration sites for incineration and power generation. The landfill method not only occupies a large amount of land, but also the leachate and odorous gases generated by the landfill will cause serious pollution to the environment.

[0003] Nowadays, domestic waste dehydration equipment is widely used. The strong pressure of the hydraulic device is used to separate the biomass waste with high water content from other difficult-to-biodegrade waste. The separated water is recycled and the separated solid waste is further processed by landfill, incineration, etc.

[0004] The process of dehydrating domestic waste using a domestic waste dehydration device is a very important step in the treatment of domestic waste. Among them, the pressure of the domestic waste dehydration device is a key factor to ensure the normal operation of the domestic waste dehydration device. When the pressure increases, the dehydration rate of domestic waste increases relatively, but at the same time, the power input will also be quite large. Due to the different domestic wastes being squeezed, the dehydration rate after squeezing is different. If the same pressure is used for squeezing, there will be problems such as excessive pressure, increased energy consumption or insufficient dehydration, and the treatment effect is poor.

[0005] With the rapid development of the Internet and the introduction of new concepts, new directions and new elements such as smart cities, how to effectively improve the treatment of domestic waste has become a new research direction. Summary of the invention

[0050] Figure 1It is a schematic block diagram of the process structure of the present invention. DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments. The illustrative embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0052] Embodiment 1:

[0053] like Figure 1 As shown, a pressure regulation method for a smart city domestic waste dehydration device based on the Internet includes the following steps:

[0054] A001: Obtain the net weight of domestic waste in each domestic waste dehydration device in the previous L days;

[0055] A002: Obtain the pressure data set of the pressure components in each domestic waste dehydration device and the amount of domestic waste dehydration in each domestic waste dehydration device in the previous L days;

[0056] A003: Determine the quality index of each domestic waste dehydration device in the previous L days based on the net weight of domestic waste in each domestic waste dehydration device and the amount of domestic waste dehydrated in each domestic waste dehydration device in the previous L days;

[0057] A004: Based on the pressure data set of the pressure parts in each domestic waste dehydration device in the previous L days, determine the operation stability value of the pressing device of each domestic waste dehydration device in the previous L days;

[0058] A005: judging the estimated value of the dehydration potential of the domestic waste on the previous L days based on the domestic waste dehydration quality measurement index and the operating stability value of the pressing device of the domestic waste dehydration device on the previous L days; and estimating the estimated value of the dehydration potential of the domestic waste on the next day using the expected model of the estimated value of the dehydration potential of the domestic waste based on the estimated value of the dehydration potential of the domestic waste on the previous L days;

[0059] A006: Adjust the pressure of the domestic waste dehydration device based on the estimated domestic waste dehydration potential for the next day.

[0060] This embodiment is mainly aimed at the existing technology of squeezing domestic waste. Due to the different types of domestic waste, even if multiple types of domestic waste are mixed together, the pressure of the domestic waste dehydration device required is still different. If the same pressure of the domestic waste dehydration device is used for dehydration and squeezing, there will be problems such as excessive pressure causing great wear and tear on the machine, and there may also be problems such as insufficient dehydration, resulting in poor domestic waste treatment effect and low efficiency.

[0061] The present technical solution is a pressure regulating method for a domestic waste dehydration device in a smart city based on the Internet, which is specifically implemented through a corresponding device, including a weight detection component for detecting the net weight of domestic waste in the domestic waste dehydration device, a pressure detection component for detecting the pressure of a pressure component of the domestic waste dehydration device, a dehydration volume detection component for detecting the dehydration rate of domestic waste in the domestic waste dehydration device, and a domestic waste dehydration device control component. The weight detection component, the pressure detection component, the dehydration volume detection component and the domestic waste dehydration device control component jointly complete the pressure regulation of the domestic waste dehydration device.

[0062] Specifically, the function of the weight detection component is to detect the weight or net weight of domestic waste added to the domestic waste dehydration device each time, and send the detected data such as the net weight of domestic waste to the domestic waste dehydration device control component or the domestic waste dehydration device control module. The function of the dehydration amount detection component is to detect the dehydration amount of domestic waste each time of each domestic waste dehydration device, that is, the dehydration amount of domestic waste each time the domestic waste dehydration device squeezes the domestic waste, and send the detected dehydration amount of domestic waste each time to the domestic waste dehydration device control component. The domestic waste dehydration device is connected to the weight detection component, the pressure detection component and the dehydration amount detection component, and receives data such as the net weight of domestic waste, the pressure of the pressure component of the domestic waste dehydration device, and the dehydration amount, and analyzes these data and then performs pressure regulation.

[0063] Specifically, in the process of squeezing by using the domestic waste dehydration device, since the amount of domestic waste put into the internal space of the domestic waste squeezing device is the same when the domestic waste dehydration device processes the domestic waste, after the same squeezing, due to the different types of domestic waste itself, the net weight of the domestic waste put in each time is different. Therefore, the net weight of the domestic waste is obtained.

[0064] When domestic waste is put into the domestic waste dehydration device for squeezing, in order to avoid damage to the squeezing device during the squeezing process, that is, the reaction force of the domestic waste on the squeezing device when the domestic waste is squeezed, the squeezing device is the core processing component of the domestic waste dehydration device for domestic waste. Pressure pieces are evenly distributed and installed at the bottom of the squeezing device. The pressure pieces can specifically be springs and other pressure pieces. The squeezing device includes multiple sub-squeezing devices, which can realize the separate squeezing of domestic waste. Multiple sub-squeezing devices constitute a squeezing device, that is, a total squeezing device.

[0065] During each squeezing process of domestic waste, the pressure detection parts are used to obtain the force exerted on the pressure parts during the entire squeezing operation. The number of pressure parts here can be four or more, and they are evenly distributed at the bottom of the squeezing device. The average force of the pressure parts is the pressure of the pressure parts detected each time during the squeezing process, that is, the pressure data set of the pressure parts of the domestic waste dehydration device.

[0066] After each squeezing of domestic waste, the squeezing is carried out according to the predetermined time. After the squeezing is completed, the domestic waste is weighed and the dehydration amount is measured, so as to obtain the dehydration amount of the domestic waste dehydration device each time.

[0067] During the domestic waste dehydration process, the above method can be used to obtain the amount of domestic waste dehydration corresponding to each domestic waste dehydration device. For example, in the previous L days, one domestic waste dehydration device had to process 5 tons of domestic waste each time, and it had to process 10 times a day. The amount of domestic waste dehydration of the domestic waste pressing device and the amount of domestic waste processed each day can be obtained according to the number of domestic waste pressing devices.

[0068] Optionally, in step A005, the specific method for determining the estimated value of the dehydration potential of domestic waste in the previous L days is:

[0069] A0051: Based on the net weight of domestic waste in each domestic waste dehydration device and the amount of domestic waste dehydrated in each domestic waste dehydration device in the previous L days, respectively obtain the average net weight of domestic waste and the average amount of domestic waste dehydrated in the domestic waste dehydration device in the previous L days;

[0070] Specifically, for the net weight of domestic waste in the domestic waste dehydration device on each of the previous L days, the corresponding mean is obtained, thereby obtaining the mean net weight of domestic waste in the domestic waste dehydration device on each of the previous L days. The mean net weight of domestic waste represents the amount of domestic waste processed by the domestic waste dehydration device each time, reflects the domestic waste processing capacity and level, and improves the environmental protection and beautiful environment of the city.

[0071] A0052: Determine the estimated value of the domestic waste dehydration potential for the previous L days based on the average net weight of domestic waste in the domestic waste dehydration device and the average amount of domestic waste dehydrated in the domestic waste dehydration device for the previous L days.

[0072] Specifically, there is a certain relationship between the estimated value of the dehydration potential of domestic waste in the previous L days, the estimated value of the dehydration potential of domestic waste, and the average value of the net weight of domestic waste and the average value of the dehydration amount of domestic waste. For example, the greater the dehydration amount of domestic waste, the greater the corresponding net weight of domestic waste, which means that the estimated value of the dehydration potential of such domestic waste is higher, and the pressure during the treatment process of the domestic waste dehydration device is reduced, and the various components work well together.

[0073] Optionally, in step A004, the specific method for determining the operation stability value of the pressing device of the domestic waste dehydration device in the previous L days is:

[0074] A0041: Based on the pressure data set of the pressure parts in each domestic waste dehydration device in the previous L days, obtain the operation stability value of the sub-pressing device of the domestic waste dehydration device in the previous L days;

[0075] A0042: Based on the operation stability value of the neutron pressing device of each domestic waste dehydration device in the previous L days, the operation stability value of the pressing device of the domestic waste dehydration device in the previous L days is obtained. The calculation formula for the operation stability value of the neutron pressing device of each domestic waste dehydration device in the previous L days is:

[0076]

[0077] Among them, M X is the operation stability value of the sub-pressing device of the X-th domestic waste dehydration device on the previous day, R is the total value of the component quantity of the pressure data set of the pressure parts of the X-th domestic waste dehydration device on the previous day, H t is the pressure of the Xth pressure piece of the pressure data set of the Xth domestic waste dehydration device on the previous day, H t-1 is the t-1th pressure piece pressure of the pressure piece pressure data set of the Xth domestic waste dehydration device on the previous day, H e is the e-th pressure piece pressure of the first t pressure piece pressures of the pressure piece pressure data set of the i-th domestic waste dehydration device on the previous day, H g is the g-th pressure piece pressure in the first t-1 pressure piece pressures of the pressure piece pressure data set of the ith domestic waste dehydration device on the previous day, and abs() is the absolute value function.

[0078] Specifically, since pressure pieces are installed on the bottom surface of the pressing device of the domestic waste dehydration device, the number of pressure pieces may be six. Due to the different distribution of domestic waste during the compression process, the pressing device may be unstable during the compression process. In the above calculation formula for the operating stability value of the pressing device, when the pressing device is not biased due to the different net weights of domestic waste in the six pressure pieces, the operating stability of the pressing device is good. That is, the pressure of the t-th pressure piece is the same as the pressure of the t-1th pressure piece in the pressure piece pressure data set recorded using the Internet, and there is no difference, which means that the operating stability of the pressing device is good.

[0079] Optionally, the calculation formula for the operation stability value of the pressing device of the domestic waste dehydration device in the previous L days is:

[0080]

[0081] Among them, M' is the operating stability value of the pressing device of the domestic waste dehydration device on the previous day, M x is the operating stability value of the sub-squeezing device of the Xth domestic waste dehydration device on the previous day, and W is the total number of operating stability values ​​of the sub-squeezing devices of the domestic waste dehydration device on the previous day.

[0082] Optionally, in step A005, the calculation formula for the estimated value of the dehydration potential of domestic waste is:

[0083] B=e U *f(M')

[0084] Among them, B is the estimated value of the domestic waste dehydration potential on the previous day, U is the domestic waste dehydration quality measurement index on the previous day, M' is the operating stability value of the pressing device of the domestic waste dehydration device on the previous day, and f() is the normalization function.

[0085] Optionally, the operating stability value of the pressing device is a calibration reference value, wherein:

[0086]

[0087] Specifically, according to the estimated value of the domestic waste dehydration potential, it can be known that the estimated value of the domestic waste dehydration potential is related to the domestic waste dehydration quality measurement index. The better the domestic waste dehydration quality measurement index data is, the more efficient the entire domestic waste treatment process is, the better the equipment operates, and the more indicators and parameters of various aspects are suitable for squeezing needs, the higher the domestic waste dehydration potential evaluation value is. On the contrary, there may be a situation where the type of domestic waste itself is not compatible with the working parameters adopted by the domestic waste dehydration device, and the working efficiency is low.

[0088] According to the above operation steps, after obtaining the estimated value of domestic waste dehydration potential of the previous L days, the estimated value of domestic waste dehydration potential of the previous L days is input into the simulated expected model of estimated value of domestic waste dehydration potential. The core of estimating the estimated value of domestic waste dehydration potential lies in the simulated expected model of estimated value of domestic waste dehydration potential.

[0089] Optionally, in step A005, in estimating the estimated value of dehydration potential of domestic waste in a future time period using the expected model of estimated value of dehydration potential of domestic waste, the operation steps of obtaining the expected model of estimated value of dehydration potential of domestic waste are:

[0090] A0053: Establishing a prediction model for the estimated value of dehydration potential of domestic waste, and obtaining simulation data of the prediction model for the estimated value of dehydration potential of domestic waste;

[0091] Specifically, the RNN network can be used to establish a model for estimating the dehydration potential of domestic waste. The model for estimating the dehydration potential of domestic waste is also called a prediction network for estimating the dehydration potential of domestic waste. The model for estimating the dehydration potential of domestic waste is a sequence prediction network that can predict the dehydration potential of domestic waste one day in the future based on the previous estimating potential of domestic waste. The specific implementation process of using the RNN network to construct the model for estimating the dehydration potential of domestic waste is common knowledge for those skilled in the art and will not be described in detail in this embodiment.

[0092] A0054: During the operation of the domestic waste dehydration device, obtain the net weight of domestic waste in each domestic waste dehydration device on day Z, the pressure data set of the pressure parts of the domestic waste dehydration device, and the dehydration amount of domestic waste in the domestic waste dehydration device;

[0093] A0055: Based on the net weight of domestic waste in each domestic waste dehydration device on day Z, obtain the domestic waste dehydration quality measurement index on day Z;

[0094] A0056: Based on the pressure data set of the pressure parts of each domestic waste dehydration device on day Z, the operating stability value of the pressing device of the domestic waste dehydration device on day Z is obtained; based on the domestic waste dehydration quality measurement index and the operating stability value of the pressing device of the domestic waste dehydration device on day Z, the estimated value of the domestic waste dehydration potential on day Z is the simulation data of the expected model of the estimated value of the domestic waste dehydration potential;

[0095] A0057: simulating the expected model of the estimated dehydration potential of domestic waste by using the simulated data of the expected model of the estimated dehydration potential of domestic waste to obtain a simulated expected model of the estimated dehydration potential of domestic waste; calculating the difference between each estimated dehydration potential of domestic waste and other estimated dehydration potential of domestic waste according to the expected model of the estimated dehydration potential of domestic waste on day Z, and obtaining the total difference between each estimated dehydration potential of domestic waste and each other estimated dehydration potential of domestic waste;

[0096] A0058: Obtain a correction reference value corresponding to each estimated value of dehydration potential of domestic waste based on the total difference between the estimated value of dehydration potential of domestic waste on day Z and each other estimated value of dehydration potential of domestic waste;

[0097] A0059: Based on the correction reference value of each simulation data of the estimated value of dehydration potential of domestic waste, the depreciation value of the expected model of the estimated value of dehydration potential of domestic waste is corrected.

[0098] Specifically, after obtaining the simulation data of the expected model of the estimated value of the dehydration potential of domestic waste, these simulation data are sent to the expected model of the estimated value of the dehydration potential of domestic waste, and the simulation data are continuous in time, so as to realize the simulation of the expected model of the estimated value of the dehydration potential of domestic waste. When training the expected model of the estimated value of the dehydration potential of domestic waste, the first part of the data in the simulation data set is used as input, and the second simulation data set of the first part of the input data is used as the corresponding network output value. Since the specific process of training the expected model of the estimated value of the dehydration potential of domestic waste using the determined simulation data set is a prior art, it will not be described in detail here.

[0099] Optionally, in step A006, the pressure of the domestic waste dehydration device is adjusted according to the estimated value of the domestic waste dehydration potential in the future time period, and the specific steps of adjusting the pressure include:

[0100] A0061: if the estimated value of the domestic waste dehydration potential predicted for the next day is greater than the critical value of the estimated value of the domestic waste dehydration potential, reducing the pressure of the domestic waste dehydration device;

[0101] A0062: If the estimated value of the domestic waste dehydration potential predicted for the next day is less than the critical value of the estimated value of the domestic waste dehydration potential, the pressure of the domestic waste dehydration device is increased.

[0102] In this embodiment, the domestic waste dehydration quality measurement index of the previous L days is determined by the net weight of domestic waste and the amount of domestic waste dehydration corresponding to the pressing device in each domestic waste dehydration device of the previous L days, and the operating stability value of the pressing device of the previous L days is obtained based on the pressure data set of the pressure parts of the pressing device in each domestic waste dehydration device of the previous L days. Then, the domestic waste dehydration potential estimated value for the next day is estimated based on the domestic waste dehydration quality measurement index of the previous L days, and based on the estimated domestic waste dehydration potential estimated value, the pressure of the domestic waste dehydration device is adjusted to avoid problems such as excessive pressure causing large wear on the device or insufficient dehydration and squeezing.

[0103] Since the dehydration potential of domestic waste is estimated on the next day, the dehydration conditions can be different according to the types of domestic waste. The pressure of the domestic waste dehydration device can be adaptively adjusted and corrected based on the dehydration conditions, thereby avoiding the use of higher pressure to press domestic waste that is easy to dehydrate and squeeze, which may cause wear on the domestic waste dehydration device, and the lack of dehydration caused by pressing domestic waste that is not easy to dehydrate, such as domestic waste with a relatively high fiber content, some cloths and clothes, etc. The pressing effect is effectively improved, the domestic waste dehydration device can be monitored, and adjustments can be made according to the situation.

[0104] The network is the loss value that determines the final training and estimation results of the network. The expected model often uses the mean difference loss value of the loss value. Since each simulated data set in the mean difference loss value is the same, there may be mutual influence between the simulated data sets. Therefore, the above proposes corresponding correction reference values ​​for different simulated data sets, and uses the correction reference values ​​to adjust the loss value, thereby improving the final simulation and estimation effect of the expected model.

[0105] If the estimated value of the dehydration potential of domestic waste in the next day is larger, it means that the equipment is stable, the treatment efficiency of this type of domestic waste is high, and the pressure and other parameters currently used are relatively appropriate. On the contrary, the pressure of the domestic waste dehydration device currently used may be larger than the standard pressure and needs to be adjusted. The specific adjustment range can be set according to actual conditions and experience, and will not be described in detail here.

[0106] Optionally, step A0058: according to the total difference between the estimated value of the dehydration potential of domestic waste on day Z and each other estimated value of the dehydration potential of domestic waste, obtain the correction reference value corresponding to each estimated value of the dehydration potential of domestic waste, and the calculation formula of the correction reference value is:

[0107] J X =1 / (1+k x )

[0108] Among them, J x is the correction reference value corresponding to the Xth estimated value of the dehydration potential of domestic waste, that is, the correction reference value corresponding to the Xth simulation data, K x It is the sum of the differences between the Xth estimated dehydration potential of domestic waste and every other estimated dehydration potential of domestic waste.

[0109] Specifically, through the correction reference value, it can be seen that when the total difference between the estimated value of the dehydration potential of domestic waste and each other estimated value of the dehydration potential of domestic waste is smaller, it means that the data simulation sets are closer.
