Intelligent supervision equipment realizes real-time monitoring and effective management of oil fume emissions by integrating components such as sensors, controllers, filtering mechanisms and actuators.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0021] Example 1: Figure 1-Figure 6As shown, an intelligent monitoring device for cooking fumes in the catering industry includes a housing 100, a monitor 104, a display controller 105, a filter cartridge 108, two sets of cleaning mechanisms 110, a liquid storage mechanism 120, a driving mechanism 130 and two sets of liquid extraction mechanisms 140.

[0022] An air inlet pipe 101 and an air outlet pipe 102 are installed on the outer surface of the housing 100. Both the air inlet pipe 101 and the air outlet pipe 102 are connected to the interior of the housing 100 and are used to connect to the oil fume exhaust pipe. The monitor 104 is installed in the housing 100. The display controller 105 is installed on the front of the housing 100 and is electrically connected to the monitor 104. The display controller 105 is used to receive information transmitted by the monitor 104 and display the information. The display controller 105 can also be used to control the operation of the components in the housing 100.

[0023] The filter cartridge 108 is installed on the inner wall of the shell 100, and the filter cartridge 108 is located directly below the air outlet pipe 102; the two sets of cleaning mechanisms 110 are used to clean the filter cartridge 108; the liquid storage mechanism 120 is located in the shell 100, and the liquid storage mechanism 120 is used to contain cleaning liquid; the driving mechanism 130 is used to drive the two sets of cleaning mechanisms 110 to operate; the two sets of liquid extraction mechanisms 140 are used to extract the cleaning liquid in the liquid storage mechanism 120 and transport the cleaning liquid to the surface of the filter cartridge 108.

[0024] Specifically, the housing 100 is mounted on a wall, and the air inlet pipe 101 and the air outlet pipe 102 are connected to the oil fume exhaust pipe. When oil fume is discharged, the oil fume enters the housing 100 through the air inlet pipe 101, and after being filtered by the filter cartridge 108, the oil fume is discharged into the oil fume exhaust pipe from the air outlet pipe 102. The monitor 104 in the housing 100 monitors the oil fume passing through the housing 100, and transmits the monitored data to the display controller 105.

[0026] like Figure 6 and Fig. 9 As shown, the cleaning mechanism 110 includes a fixed plate 111, two hydraulic cylinders 112, a cleaning brush 113 and a bump 114. The two hydraulic cylinders 112 are both mounted on the fixed plate 111; the cleaning brush 113 is fixedly connected to the extended ends of the two hydraulic cylinders 112, and the cleaning brush 113 is in contact with the filter cartridge 108; the bump 114 is mounted on the side of the fixed plate 111 away from the hydraulic cylinder 112.

[0027] Specifically, when the fixing plate 111 rotates, the cleaning brush 113 is driven to rotate through the hydraulic cylinder 112, and the cleaning brush 113 cleans the surface of the filter cartridge 108; when it is necessary to adjust the pressure of the cleaning brush 113 on the filter cartridge 108, the two hydraulic cylinders 112 are started so that the hydraulic cylinders 112 push the cleaning brush 113 to move, and the cleaning brush 113 moves relative to the filter cartridge 108, thereby adjusting the pressure of the cleaning brush 113 on the filter cartridge 108.

[0028] like Figure 4-Figure 7 As shown, the liquid storage mechanism 120 includes a box body 121 , a plurality of vertical rods 122 , a plurality of stirring rods 123 and a plurality of gears 124 .

[0029] The box body 121 is installed on the inner bottom surface of the shell 100, and the box body 121 is annular; a liquid adding pipe (not shown) is installed on the box body 121, and the liquid adding pipe extends to the outside of the shell 100 (not shown). By setting the liquid adding pipe, it is convenient to add cleaning liquid into the box body 121. The cleaning liquid is a mixture of oil cleaning agent and water.

[0030] The multiple vertical rods 122 are all rotatably connected to the box body 121; the multiple stirring rods 123 are all located in the box body 121, and the multiple stirring rods 123 are respectively installed on the multiple vertical rods 122; the multiple gears 124 are located outside the box body 121, and the multiple gears 124 are respectively fixedly connected to the multiple vertical rods 122.

[0031] Specifically, by adding cleaning liquid into the box body 121; when the gear 124 rotates, it will drive the vertical rod 122 to rotate, and then drive the multiple stirring rods 123 to rotate, so that the stirring rods 123 stir the cleaning liquid in the box body 121, thereby avoiding stratification and segregation of the cleaning liquid.

[0032] like Figure 5-Figure 9 As shown, the driving mechanism 130 includes a mounting plate 131, a motor 132, a protective cover 133, a connecting plate 134 and a gear ring 135. The mounting plate 131 is mounted on the box body 121; the motor 132 is mounted on the top surface of the mounting plate 131; the protective cover 133 is mounted on the power output shaft of the motor 132; the connecting plate 134 is fixedly connected to the upper end of the power output shaft of the motor 132, and the connecting plate 134 is fixedly connected to the two fixing plates 111; the gear ring 135 is fixedly connected to the connecting plate 134, and the gear ring 135 is meshed with the plurality of gears 124.

[0033] Specifically, when the motor 132 is running, the power output shaft of the motor 132 will drive the connecting plate 134 to rotate, thereby driving the two sets of cleaning mechanisms 110 to rotate, and then the two cleaning mechanisms 110 clean the filter cartridge 108 .

[0034] When the connecting plate 134 rotates, the gear ring 135 is also driven to rotate, thereby meshing and driving the plurality of gears 124 to rotate simultaneously.

[0035] The protective cover 133 can be provided to prevent the oil stains cleaned by the cleaning brush 113 from falling on the motor 132 , thereby protecting the motor 132 .

[0036] like Figure 8 and Fig. 9 As shown, the pumping mechanism 140 includes a mounting frame 141, a piston cylinder 142, a push plate 146, a spring 145, a hollow ring 147 and a through groove 148. The mounting frame 141 is mounted on the inner wall of the housing 100; the piston cylinder 142 is mounted on the mounting frame 141, a piston sheet is slidably connected inside the piston cylinder 142, a piston rod is mounted on the piston sheet, the piston rod extends to the outside of the piston cylinder 142, a pumping tube 143 and a liquid infusion tube 144 are mounted on the piston cylinder 142, and the other end of the pumping tube 143 extends into the box body 121; the push plate 146 is fixedly connected to one end of the piston rod located outside the piston cylinder 142, and a groove matching the protrusion 114 is opened on the push plate 146; the two ends of the spring 145 are respectively connected to the piston cylinder 142 and the push plate 146. The hollow ring 147 is installed on the inner top surface of the shell 100 , and the hollow ring 147 is sleeved on the filter cartridge 108 . The hollow ring 147 is fixedly connected to one end of the infusion tube 144 . The through groove 148 is annular and is opened on the inner wall of the hollow ring 147 .

[0037] One-way valves are installed in both the suction tube 143 and the infusion tube 144, so that the cleaning liquid in the box body 121 can only enter the piston cylinder 142 through the suction tube 143 in one direction, and the cleaning liquid in the piston cylinder 142 can only enter the hollow ring 147 through the infusion tube 144 in one direction.

[0038] Specifically, when the push plate 146 moves in a direction away from the piston cylinder 142 , the piston rod pulls the piston plate to move, thereby pumping the cleaning liquid in the box body 121 into the piston cylinder 142 through the liquid pumping tube 143 .

[0039] When the push plate 146 moves toward the direction of the piston cylinder 142, the push plate 146 pushes the piston plate to move through the piston rod, and then the cleaning liquid in the piston cylinder 142 is transported to the hollow ring 147 through the liquid delivery tube 144. By reciprocating the push plate 146 horizontally, the cleaning liquid in the box 121 is continuously transported to the hollow ring 147, and the cleaning liquid in the hollow ring 147 flows out through the through groove 148, and finally flows to the filter cylinder 108, so that the cleaning liquid cooperates with the cleaning brush 113 to clean the filter cylinder 108.

[0040] like Figure 1-Figure 3As shown, the intelligent monitoring device for cooking fume in the catering industry also includes a plurality of bolts 103, a discharge hopper 106 and a sealing cover 107. The plurality of bolts 103 are all mounted on the housing 100; the discharge hopper 106 is mounted on the bottom surface of the housing 100, the discharge hopper 106 is located directly below the filter cartridge 108, and the discharge hopper 106 is connected to the inside of the housing 100; the sealing cover 107 is threadedly connected to the lower end of the discharge hopper 106.

[0041] Specifically, the housing 100 can be mounted on a wall by providing a plurality of bolts 103. The grease removed by the cleaning brush 113 can be collected by providing a discharge hopper 106, and the grease in the discharge hopper 106 can be led out by providing a sealing cover 107.

[0042] Working principle: During specific use, the shell 100 is installed on the wall by using multiple bolts 103, and the air inlet pipe 101 and the air outlet pipe 102 are connected to the oil fume exhaust pipe. When oil fume is discharged, the oil fume will enter the shell 100 through the air inlet pipe 101, and after being filtered by the filter cartridge 108, the oil fume will be discharged from the air outlet pipe 102 to the oil fume exhaust pipe, and the monitor 104 in the shell 100 will monitor the oil fume passing through the shell 100 and transmit the monitored data to the display controller 105.

[0043] When the filter cartridge 108 needs to be cleaned, the motor 132 is started so that the power output shaft of the motor 132 drives the connecting plate 134 to rotate, thereby driving the two fixing plates 111 to rotate, and then driving the cleaning brush 113 to rotate through the hydraulic cylinder 112, and then the filter cartridge 108 is cleaned by the two cleaning brushes 113.

[0044] When the fixed plate 111 rotates, the protrusion 114 will also be driven to rotate. The rotating protrusion 114 will intermittently contact the push plate 146. When the protrusion 114 contacts the push plate 146, the protrusion 114 will push the push plate 146 to move toward the direction close to the piston cylinder 142. The push plate 146 will push the piston plate to move through the piston rod, and then the cleaning liquid in the piston cylinder 142 will be transported to the hollow ring 147 through the infusion tube 144.

[0045] When the protrusion 114 is separated from the push plate 146, the spring 145 pushes the push plate 146 to move away from the piston cylinder 142 due to the rebound force, and the piston plate is pulled to move through the piston rod, thereby pumping the cleaning liquid in the box 121 into the piston cylinder 142 through the liquid pumping tube 143. The cooperation of the rotating protrusion 114 and the spring 145 will cause the push plate 146 to reciprocate, and then continuously transport the cleaning liquid in the box 121 to the hollow ring 147, and the cleaning liquid in the hollow ring 147 will flow out through the through groove 148, and finally the cleaning liquid will flow to the filter cartridge 108, so that the cleaning brush 113 and the cleaning liquid cooperate to clean the filter cartridge 108.

[0046] When the motor 132 drives the connecting plate 134 to rotate, it will also drive the gear ring 135 to rotate. The rotating gear ring 135 will mesh and drive the multiple gears 124 to rotate, and then drive the multiple vertical rods 122 and the multiple stirring rods 123 to rotate, so that the stirring rods 123 stir the cleaning liquid in the box body 121, thereby avoiding stratification and segregation of the cleaning liquid, thereby facilitating the cleaning of the filter cartridge 108 with the cleaning liquid.

[0047] The oil stains cleaned by the cleaning brush 113 will move downward, and some of the oil stains will fall directly into the discharge hopper 106; some of the oil stains will fall onto the protective cover 133, and these oil stains will flow downward along the slope of the protective cover 133, and finally fall into the discharge hopper 106; then the oil stains in the discharge hopper 106 can be discharged by unscrewing the sealing cover 107.

[0048] Example 2: Figure 1-Figure 10 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: An intelligent monitoring device for cooking fumes in the catering industry also includes a control system; The control system includes: a data collection module, a data analysis module, a data acquisition module and a time prediction module. The modules are connected by wired / wireless means to realize data transmission.

[0049] The data acquisition module is used to collect comprehensive data information of intelligent monitoring equipment, where the comprehensive data information includes oil stain thickness, temperature, contact pressure and cumulative working time.

[0050] The oil stain thickness refers to the thickness of the oil stain on the surface of the filter cartridge 108 . The oil stain thickness can be measured in real time using a laser ranging sensor.

[0051] The temperature refers to the surface temperature of the filter cartridge 108 , and the temperature can be obtained by measuring the filter cartridge 108 with an infrared temperature sensor.

[0052] The contact pressure refers to the pressure when the cleaning brush 113 contacts the surface of the filter cartridge 108 . The contact pressure between the cleaning brush 113 and the surface of the filter cartridge 108 can be measured in real time by installing a pressure sensor on the cleaning brush 113 .

[0053] The accumulated working time refers to the accumulated working time of the cleaning brush 113 , that is, the accumulated working time of the cleaning brush 113 cleaning the filter cartridge 108 . The accumulated working time can be obtained by recording through a timer.

[0054] The data analysis module is used to receive the threshold range of the speed influence coefficient preset by the user, generate the speed influence coefficient according to the comprehensive data information, and then compare the speed influence coefficient with the threshold range of the preset speed influence coefficient to determine and generate the corresponding speed level; The speed influence coefficient is generated as follows: ; In the formula, is the speed influence coefficient, is the thickness of oil stain on the surface of the filter cartridge 108, is the surface temperature of the filter cartridge 108, is the pressure when the cleaning brush 113 contacts the surface of the filter cartridge 108, is the cumulative working time of the cleaning brush 113, , , and are all weight coefficients, which are determined by technicians in this field according to specific application requirements. , , and All are greater than 0; The thicker the oil stain on the surface of the filter cartridge 108 is, the greater the cleaning force and the longer the cleaning time are needed to remove it. Therefore, the thicker the oil stain is, the more difficult it is to clean it, and the rotation speed of the cleaning brush 113 needs to be increased to maintain the cleaning effect. The higher the surface temperature of the filter cartridge 108, the lower the viscosity of the oil, and the easier it is to clean. On the contrary, the lower the temperature, the higher the solidification degree of the oil, and the more difficult it is to clean. It is necessary to increase the rotation speed of the cleaning brush 113 to maintain the cleaning effect. The greater the pressure when the cleaning brush 113 contacts the surface of the filter cartridge 108, the better the cleaning effect and the lower the cleaning difficulty. On the contrary, when the pressure when the cleaning brush 113 contacts the surface of the filter cartridge 108 is smaller, the greater the cleaning difficulty and the rotation speed of the cleaning brush 113 needs to be increased to maintain the cleaning effect. The longer the cumulative working time of the cleaning brush 113 is, the more the bristles of the cleaning brush 113 are worn, the lower the cleaning efficiency is, and the more difficult the cleaning is, so it is necessary to increase the rotation speed of the cleaning brush 113 to maintain the cleaning effect; and vice versa.

[0055] It should be noted that the formulas involved in the above-mentioned are all calculated by removing dimensions and taking numerical values. They are a formula that is closest to the actual situation obtained by collecting a large amount of data and performing software simulation. The weight coefficients in the formulas and the various preset thresholds in the analysis process are set by technical personnel in this field according to actual conditions or obtained by simulating a large amount of data; the size of the weight coefficient is to quantify each parameter to obtain a specific value for subsequent comparison. The size of the weight coefficient depends on the amount of sample data and the corresponding processing coefficients initially set by technical personnel in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameters and the quantized values.

[0056] The speed levels are generated as follows: The speed levels include a first speed, a second speed and a third speed, wherein the first speed, the second speed and the third speed are successively increased, and the first speed, the second speed and the third speed are all the speeds of the motor 132. Since the cleaning mechanism 110 is driven by the motor 132, the speed of the motor 132 is the same as the speed of the cleaning mechanism 110. The threshold range of the preset speed influence coefficient is , , < ; like , indicating that the cleaning difficulty of the filter cartridge 108 is relatively low, at this time, the data analysis module generates a primary speed; like , indicating that the cleaning difficulty of the filter cartridge 108 is moderate, at this time, the data analysis module generates a secondary speed; like , indicating that the cleaning difficulty of the filter cartridge 108 is relatively high. At this time, the data analysis module generates a third-level rotation speed.

[0057] in, and It is determined by those skilled in the art according to specific application requirements.

[0058] Exemplarily, the speeds of motor 132 corresponding to the first-level speed, the second-level speed, and the third-level speed are 700 rpm, 900 rpm, and 1100 rpm, respectively; the speed of motor 132 can also be customized according to specific circumstances; the speed of motor 132 is controlled according to the corresponding speed level.

[0059] According to the corresponding speed level, the data analysis module generates a corresponding speed level control signal. For example, when the speed level is level one, the data analysis module generates a level one speed control signal, and then sends the level one speed control signal to the controller of the motor 132, thereby controlling and adjusting the speed of the motor 132, and thereby adjusting the speed of the cleaning mechanism 110.

[0060] The data acquisition module is used to collect a historical training data set of the intelligent monitoring device, and the historical training data set includes cleaning comprehensive impact data and cleaning duration; wherein the cleaning comprehensive impact data includes comprehensive data information and speed data of the motor 132, and the speed data of the motor 132 can be obtained through a Hall effect sensor; The cleaning time refers to the time from when the cleaning brush 113 starts cleaning the filter cartridge 108 to when the cleaning of the filter cartridge 108 is completed. The cleaning time can be obtained by a timer.

[0061] The time prediction module trains a machine learning model to predict the cleaning time based on the historical training data set, collects real-time cleaning comprehensive impact data, and inputs it into the trained machine learning model to predict the cleaning time; The training method of the machine learning model that predicts cleaning time includes: Convert the collected comprehensive cleaning impact data into a corresponding set of feature vectors; Each set of feature vectors is used as the input of the machine learning model. The machine learning model takes the cleaning time corresponding to each set of comprehensive cleaning impact data as the output, the actual cleaning time corresponding to each set of comprehensive cleaning impact data is used as the prediction target, and minimizing the loss function value of the machine learning model is used as the training target; training is stopped when the loss function value of the machine learning model is less than or equal to the preset target loss value.

[0062] The machine learning model can be one of the models such as SVM regression, random forest regression or neural network regression.

[0063] The loss function value of the machine learning model is the mean square error; Mean square error is one of the commonly used loss functions. Minimization is used as the goal to train the model so that the machine learning model better fits the data, thereby improving the performance and accuracy of the model; In the loss function is the loss function value of the machine learning model, x is the feature vector group number; m is the number of feature vector groups; is the cleaning time predicted by the x-th group of feature vectors, is the actual cleaning time corresponding to the xth group of feature vectors; Other model parameters of the machine learning model, target loss value, optimization algorithm, training set test set validation set ratio, and loss function optimization are all achieved through actual engineering implementation and continuous experimental tuning.

[0064] The running time of the motor 132 is controlled according to the predicted cleaning time; when the running time of the motor 132 is the same as the predicted cleaning time, the motor 132 is powered off and stopped.

[0065] To summarize, the control system collects comprehensive data information such as oil thickness, temperature, contact pressure and cumulative working time in real time through the data acquisition module. The data analysis module generates a speed influence coefficient based on this information, and judges and generates a corresponding speed level, thereby controlling the speed of the motor 132, reducing energy consumption while maintaining the cleaning effect; the time prediction module in the control system is based on a historical training data set, and trains a machine learning model to predict the cleaning time, which can predict the time required for cleaning, thereby more accurately controlling the operating time of the motor 132 and further reducing energy consumption.

[0066] Furthermore, the control system can automatically adjust the rotation speed of the cleaning mechanism 110 according to the cleaning difficulty of the filter cartridge 108 without manual intervention.
