Description

Technical Field

[0001] The present invention relates to the technical field of agricultural waste treatment, in particular to a method and system for controlling a load of agricultural waste treatment equipment, agricultural waste treatment equipment and a medium. Background Art

[0002] The existing agricultural pollution equipment control working conditions mainly include the following:

[0003] (1) Manual control, that is, on-site personnel adjust the start and stop and operation mode of the fan, booster pump and return pump in real time by understanding the online data and operating parameters of the equipment.

[0004] (2) PID control, that is, the linkage between online data and fans, water pumps and return pumps, and through the combination with PLC and other hardware, real-time adjustment of system operating conditions can be achieved.

[0005] (3) Robust control, that is, based on the water quality model, by comparing the real-time collected online data with the model, the system's air supply, processing volume, and return volume are controlled to ensure that the system has a good buffer when it is impacted by water quantity and quality.

[0006] However, the related technical solutions have the following disadvantages:

[0007] (1) Manual control: A large number of on-site operators are required. In addition, the manpower cost is high due to the dispersion of agricultural pollution sites and the volatility of water quality and quantity. The system operating conditions need to be adjusted in real time around the clock. Therefore, it is difficult for the system to stably produce water that meets the standards.

[0008] (2) PID control requires the fan, water pump and reflux to be linked with online data. Although PID control can achieve precise control and the system can achieve good dynamic response, accurate inlet and outlet water volume and quality data are required to achieve precise regulation of online data. The requirements for online instruments are very high, the investment cost of the equipment is large, and the measurement accuracy of online detection equipment is low. The long-term accumulated measurement error still requires manual calibration by the operation and maintenance personnel, which does not reduce the intensity of on-site operations.

[0009] (3) Robust control: It is necessary to model the changes in water quality and quantity at agricultural pollution sites, which is difficult to operate. In addition, the conditions at various agricultural pollution sites vary greatly, making it difficult to operate. Summary of the invention

[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limitations of the present invention. For the step numbers in the following embodiments, they are only provided for the convenience of explanation, and the order between the steps is not limited in any way. The execution order of each step in the embodiment can be adaptively adjusted according to the understanding of those skilled in the art.

[0043] In view of the defects and deficiencies of the control method for agricultural sewage treatment in the relevant technical solutions pointed out in the background technology: In rural sewage treatment equipment, A 2 The control of the O process has the characteristics of large time lag, nonlinearity and strong interference. At the same time, in response to the large fluctuations in the quality and quantity of rural sewage, the relevant sensors in agricultural sewage equipment are expensive, and someone is required to adjust the working conditions on site, resulting in increased labor costs, and it is impossible to link with the working conditions in real time, dynamically adjust the dosage and proportion of the dosing, and the control model is complex and has low stability, and the control strategy does not respond in time. A fuzzy control is proposed, which is low in price, quick in response, strong in anti-interference ability, and has few people to maintain and unattended. New working condition control scheme.

[0044] In the first aspect, Figure 1 As shown, the technical solution of the present application provides a method for controlling the load of agricultural waste treatment equipment; the method comprises steps S100-S300:

[0045] S100, obtaining a first value of dissolved oxygen sampling, and performing convolution calculation on the first value and a preset first attenuation function to obtain a second value of dissolved oxygen;

[0046] Among them, the first value can be a value measured by an online dissolved oxygen (DO) meter, that is, the measured value of dissolved oxygen; the second value refers to the convolution of the measured online dissolved oxygen value and the attenuation function, that is, the value obtained by multiplying the measured value by the weight corresponding to the attenuation function. Specifically in the embodiment, the load operation logic of the embodiment is to convolve the currently collected online DO value with the set attenuation function, that is, the sampled value multiplied by the weighted value and the sum is used to judge the DO value of the load, and the judgment mode is subsequently triggered according to the DO value obtained by the measurement. The first attenuation function in the embodiment includes but is not limited to linear attenuation or exponential attenuation; it can also be changed according to the system characteristics in the implementation scenario.

[0047] In some feasible embodiments, in the step of obtaining a first value of dissolved oxygen sampling, performing convolution calculation on the first value and a preset first attenuation function to obtain a second value of dissolved oxygen, the calculation formula of the second value is:

[0048]

[0049] in DO 计算 is the second value, that is, the measured value of DO multiplied by the weight corresponding to the attenuation function. 测量 is the first value, namely the measured value of dissolved oxygen; G(x) is the first attenuation function.

[0050] S200, obtaining a third value of the flow sample, and performing convolution calculation on the third value and a preset second attenuation function to obtain a fourth value of the flow;

[0051] Among them, the third value can be a flow value obtained by an online flow meter; the fourth value is the convolution of the value of the measured flow meter and the attenuation function, that is, the value obtained by multiplying the measured value by the weight corresponding to the attenuation function; the second attenuation function in the embodiment is the same as the first attenuation function in step S100. Specifically in the embodiment, the load operation logic of the embodiment is to convolve the currently collected online flow value with the set attenuation function, that is, the sum of the sampled value multiplied by the weighted value is the DO value for judging the load, and the judgment mode is subsequently triggered according to the DO value obtained by the measurement. The second attenuation function in the embodiment includes but is not limited to linear attenuation or exponential attenuation, and can also be changed according to the system characteristics in the implementation scenario.

[0052] In some feasible embodiments, in the step of obtaining the third value of the flow sample, performing convolution calculation on the third value and the preset second attenuation function to obtain the fourth value of the flow, the calculation formula of the fourth value is:

[0053]

[0054] in Q 计算 is the fourth value, i.e., the value obtained by multiplying the measured flow value by the weight corresponding to the attenuation function, Q 测量 is the third value, that is, the value obtained by the online flow meter, and G′(x) is the second attenuation function.

[0055] S300, determining a system operating condition according to the second value and the fourth value, determining an operating mode of a system device according to the system operating condition, and controlling the system device to operate according to the operating mode;

[0056] Specifically in the embodiment, a double load judgment is performed based on the DO value and flow value calculated in step S100 and step S200 to determine the system working condition at the current moment. By controlling the start and stop mode of the system equipment, such as the fan and the water pump, the system can be switched between low load, normal mode and high load.

[0057] In some feasible embodiments, the system equipment may include, but is not limited to, a water pump and a fan. Further, in the embodiment, the system operating condition is determined according to the second value and the fourth value, the operation mode of the system equipment is determined according to the system operating condition, and the step S300 of controlling the operation of the system equipment according to the operation mode may include step S310:

[0058] S310, determining that the second value is greater than a preset first threshold value, and the fourth value is not less than a preset third threshold value, maintaining at least one fan in a normally open operation mode, and controlling the water pump in an intermittent operation mode.

[0059] Specifically in the embodiment, it is load mode 1 in the embodiment. When the calculated DO value is greater than 5mg / L, that is, the first threshold value, the optimal ratio can be determined according to the on-site commissioning personnel in the embodiment. The embodiment enters flow judgment. If the flow measurement value exceeds 8.3m3 / h, it is determined whether the two fans are turned on, and a high flow alarm is issued to the background operation platform. For example, after the two fans are started, the water pump enters the intermittent operation mode. The water pump is turned on for two hours and stopped for two hours. One fan is always on, and the other adopts the intermittent operation mode, which is turned on for one hour and stopped for one hour. For another example, if only one fan is running, the water pump enters the intermittent operation mode, and the fan maintains the current operating condition.

[0060] In some feasible implementations, the method determines the system operating condition according to the second value and the fourth value, determines the operating mode of the system device according to the system operating condition, and controls the operation of the system device according to the operating mode. In step S300, step S320 may be included:

[0061] S320, determining that the second value is greater than the first threshold value and the fourth value is less than the third threshold value, maintaining at least one fan in the intermittent operation mode, and controlling the water pump to be in the normally open operation mode.

[0062] Specifically in the embodiment, that is, load mode 2 in the embodiment, when the calculated DO value is greater than 5mg / L and the calculated flow value is less than 8.3m3 / h, it is determined whether the two fans are turned on; for example, if the two fans are always on, one fan is always on, and the other adopts an intermittent operation mode, which is turned on for one hour and stopped for one hour. The water pump is in a continuous operation mode. If only one fan is running, the fan is turned on for one hour and stopped for one hour, and the water pump enters a continuous operation mode.

[0063] In some feasible implementations, the method determines the system operating condition according to the second value and the fourth value, determines the operating mode of the system device according to the system operating condition, and controls the system device to work according to the operating mode. In this step S300, step S330 may be included:

[0064] S330, determining that the second value is less than a preset second threshold value, maintaining the two fans in a normally-on operation mode, and controlling the water pump in an intermittent operation mode.

[0065] Specifically in the embodiment, in load mode three of the embodiment, when the calculated DO value is less than 1.5mg / L, the system enters flow judgment. If the flow measurement value exceeds 8.3m3 / h, it determines whether the two fans are turned on, and at the same time sends a high-flow and high-load alarm to the back-end operating platform. For example, after the two fans start, the fans maintain the current operating mode, and the water pump enters the intermittent operation mode, starting for two hours and stopping for two hours; for another example, if only one fan is running, the other fan is turned on, and the water pump enters the intermittent operation condition, starting for two hours and stopping for two hours.

[0066] Alternatively, when the calculated DO value is less than 1.5 mg / L, the embodiment enters flow judgment. If the calculated flow value does not exceed 8.3 m3 / h, it determines whether the two fans are turned on. For example, after the two fans are started, the water pump enters the intermittent operation mode, starting for two hours and stopping for two hours. For example, if only one fan is running, the other fan is turned on and the water pump enters the intermittent operation condition.

[0067] In some feasible embodiments, when the calculated DO value is 1.5-5 mg / L, the embodiment enters flow judgment. If the calculated flow value exceeds 8.3 m3 / h, it enters intermittent operation mode, and the device of the embodiment enters an intermittent operation mode of two starts and two stops; if the calculated flow value does not exceed 8.3 m3 / h, the current operation mode is maintained. In addition, in order to ensure the requirements for the amount of water to be processed, the embodiment adds a reset button under low-load conditions, and manually restores to the continuous operation mode according to the actual situation to avoid the system running at low water volume for a long time, which reduces the processing volume.

[0068] In some feasible embodiments, the embodiment determines the system operating condition according to the second value and the fourth value, determines the operating mode of the system device according to the system operating condition, and controls the system device to work according to the operating mode. After step S300, the method further includes step S400:

[0069] S400, obtaining a fifth value of the sludge change, and determining the sludge discharge frequency and the sludge discharge time according to the fifth value;

[0070] Specifically in the embodiment, the embodiment can observe the changes in sludge SV30 in different periods and seasons through the online SV30 equipment, determine the frequency and duration of sludge discharge, such as in summer when the temperature is high, the sludge discharge amount can be controlled according to the value of the online SV30, and the sludge age can be compressed to 10-13 days. For example, in winter when the temperature is low, below 15°C, the sludge discharge cycle can be controlled to 15-20 days according to the value of the online SV30, and the sludge age can be appropriately extended, which is beneficial for application in low-temperature and high-concentration water bodies in the north, and is beneficial to the nitrification of water bodies.

[0071] On the other hand, the technical solution of the present application also provides a load control system for agricultural waste treatment equipment, the system comprising:

[0072] a dissolved oxygen determination unit, configured to obtain a first value of dissolved oxygen sampling, and perform convolution calculation on the first value and a preset first attenuation function to obtain a second value of dissolved oxygen;

[0073] A flow determination unit, configured to obtain a third value of the flow sample, and perform convolution calculation on the third value and a preset second attenuation function to obtain a fourth value of the flow;

[0074] The working mode determination unit is used to determine the system working condition according to the second value and the fourth value, determine the operating mode of the system equipment according to the system working condition, and control the operation of the system equipment according to the operating mode.

[0075] In some feasible embodiments, the agricultural waste treatment equipment load control system may also be provided with a remote control platform to observe the working state of the system in real time and observe whether the system issues an alarm. By obtaining hourly data of online DO values, flow meters, etc., the working state of the system can be better adjusted.

[0076] On the other hand, the technical solution of the present application also provides agricultural waste treatment equipment; it includes:

[0077] At least one processor; at least one memory, the memory being used to store at least one program; when the at least one program is executed by the at least one processor, the at least one processor runs the agricultural waste treatment equipment load control method as in the first aspect.

[0078] An embodiment of the present invention further provides a storage medium storing a corresponding execution program, which is executed by a processor to implement the agricultural waste treatment equipment load control method in the first aspect.

[0079] From the above specific implementation process, it can be concluded that the technical solution provided by the present invention has the following advantages or strengths compared with the prior art:

[0080] (1) The technical solution of the present application eliminates the frequency converters for fans and water pumps and adopts an intermittent operation mode, which effectively reduces the investment cost and can adapt to the on-site use environment of agricultural sewage equipment.

[0081] (2) The technical solution of this application can increase / decrease the air supply in advance by setting different DO value trigger conditions and starting and stopping more than one fan, which can better adapt to the water quality fluctuations at the agricultural sewage site, and avoid the impact of abnormal water quality and water volume on the system by setting the intermittent operation mode. Intermittent operation can play the role of peak shaving and valley filling, which can better adapt to the fluctuations in water quality and water volume of rural sewage and avoid the impact of different sampling cycles and sampling accuracies on the dynamic performance of the system during the inverter data acquisition process.

[0082] (3) The technical solution of the present application uses the convolution between the DO value and the attenuation function to calculate the DO value as the trigger condition, avoiding system misoperation caused by using only the current DO value, which is beneficial to reducing the impact of online value fluctuations on the system. At the same time, by setting different attenuation functions, the processing conditions of the system can be better reflected.

[0083] (4) The technical solution of the present application avoids the numerical modeling of water quality and quantity models and simplifies the control logic by dividing the fuzzy control into the dosing mode and the non-dosing mode, and further subdividing the different decisions under the two modes.

[0084] (5) The technical solution of the present application reasonably sets the sampling cycle, which can avoid frequent starting and stopping of the equipment and is beneficial to the maintenance of the equipment. At the same time, the online SV30 data can reflect the SV30 changes of the system in different periods and seasons in real time, which is beneficial to adjust the frequency and intensity of mud discharge.

[0085] (6) The technical solution of this application is equipped with a remote engineering alarm system, which can monitor the working condition data in real time, observe the working condition of the equipment, and the running time of each sub-equipment such as air pump, water pump and fan, online DO, and hourly data of flow meter. It is in line with the characteristics of decentralized rural sewage.
