BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to more clearly illustrate the specific embodiments of the present invention, the drawings required for use in the embodiments are briefly introduced below.

[0034] Figure 1 It is a schematic diagram of a method for energy saving and energy reduction based on vision and machine speed coupling provided by the present invention.

[0035] Figure 2 It is a schematic diagram of a system for saving energy and reducing consumption based on vision and machine speed coupling provided by the present invention. DETAILED DESCRIPTION

[0036] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0037] In view of the fact that the air pressure supply of the current cigarette packaging machine cannot be adjusted according to the equipment status, the present invention provides a method and system for saving energy and reducing consumption based on vision and machine speed coupling, which solves the problem that the air pressure supply of the existing cigarette packaging machine cannot be adjusted according to the equipment operation status, which easily causes energy loss. It can improve the intelligence of the air pressure supply system of the packaging machine and reduce the energy loss of equipment operation.

[0038] like Figure 1 As shown, a method for energy saving and energy reduction based on vision and machine speed coupling includes:

[0039] S1: Capture video of the pressure gauge of the cigarette packaging machine, identify the pressure gauge reading based on the video image of the pressure gauge, and then store it in the air pressure database of the industrial computer.

[0040] S2: Obtain the operating frequency and operating current of the cigarette packaging machine motor through the motor inverter and store them in the equipment status database of the industrial computer.

[0041] S3: The industrial computer is provided with a fitting algorithm to fit the corresponding data in the air pressure database and the device status database.

[0042] S4: The industrial computer adjusts the proportional regulating valves at the outlets of the positive pressure and negative pressure pipelines according to the fitted values, so that the air pressure supply is adjusted according to the operating status of the equipment.

[0043] Specifically, a visual recognition device is installed at the position of the pressure gauge of the packaging machine to identify the values ​​of the mechanical pointer pressure gauge and the digital pressure gauge in real time. The identified values ​​are stored in the air pressure database of the industrial computer. The frequency, voltage, current and other data of the motor inverter are retrieved through the PLC and stored in the equipment status database. The air pressure database and the equipment status database are fitted so that when the frequency or current is 0, the air pressure value is reduced to the basic operating air pressure of the packaging machine by adjusting the proportional regulating valve installed at the outlet of the positive pressure and negative pressure pipelines. Finally, the air pressure changes with the machine operation state. At the same time, when the machine speed is 0, the positive and negative pressure states are reduced to the basic pressure state. This method can improve the intelligence of the air pressure supply system of the packaging machine and reduce the energy loss of equipment operation.

[0044] The method also includes: setting a corresponding table between the running speed of the packaging machine and the air pressure, and the industrial computer controls the opening of the proportional regulating valve according to the corresponding table to adjust the air pressure supply.

[0045] In actual application, the industrial computer controls the positive and negative pressure values ​​according to the pressure gauge reading. When the pressure is high and the speed of the packaging machine is at the lowest or 0, the pressure is reduced to the basic pressure. When the speed is at 0 for more than 3 minutes, the pressure is reduced to the maintenance pressure (0.35 MPa). The specific corresponding thresholds are shown in Table 1.

[0046]

[0047] Furthermore, the step of collecting video of the pressure gauge of the cigarette packaging machine and identifying the pressure gauge reading according to the video image of the pressure gauge includes:

[0048] Collect pressure gauge images at different angles, scales, and brightness;

[0049] A neural network image recognition model is set, and the pressure gauge image is imported into the neural network image recognition model for training to be used for identifying the pressure gauge reading.

[0050] Furthermore, the method of collecting video of the pressure gauge of the cigarette packaging machine and identifying the pressure gauge reading according to the video image of the pressure gauge also includes:

[0051] The pressure gauge images of digital pressure gauges and pointer pressure gauges are collected, and the pressure gauge images are gray-processed, and then the pressure gauge readings are recognized through OCR.

[0052] In practical applications, the pointer pressure gauge data is monitored in real time by industrial cameras, and the digital pressure gauge data is superimposed through neural network and OCR recognition, and then processed by visual processing methods such as grayscale processing. The specific processing process is as follows:

[0053] Collect digital and pointer pressure gauge images at different angles, scales, and brightness and import them into the CNN neural network for training. Constantly adjust the values ​​and stacking layers to accurately identify and distinguish the images of digital and pointer pressure gauges, and enter different processes respectively.

[0054] Pointer pressure gauge recognition structure construction: Binarize the image of the pointer instrument and perform grayscale processing to maximize the image clarity and features. OCR recognizes the grayscale processed numbers. And recognizes the digital interval with pointer lines. Divide the interval into equal intervals according to the distance between adjacent scale numbers. Read the first and last numbers of the recognized interval, estimate the pressure gauge reading according to the ratio of the distance between the scale lines and the two numbers, and record it in the database.

[0055] The digital pressure gauge is processed by grayscale and the reading is directly recognized by OCR and recorded in the database.

[0056] Further, the fitting of the corresponding data in the air pressure database and the device status database includes:

[0057] The corresponding pressure gauge reading, the operating frequency and the operating current are fitted.

[0058] Furthermore, the air pressure supply is adjusted according to the operating state of the equipment, including:

[0059] When the operating frequency or the operating current is 0, the air pressure value is controlled to be reduced to the basic operating air pressure of the packaging machine.

[0060] It can be seen that the present invention provides a method for saving energy and reducing consumption based on vision and machine speed coupling, collects video of the pressure gauge of the cigarette packaging machine, identifies the pressure gauge reading, obtains the operating frequency and operating current of the cigarette packaging machine motor through the motor inverter, and the industrial computer adjusts the positive and negative pressure values ​​of the packaging machine according to the fitting values ​​of the pressure gauge reading, operating frequency and operating current, so that the air pressure supply is adjusted according to the operating state of the equipment.

The PLC controller is connected to the motor inverter signal of the cigarette packaging machine to obtain the operating frequency and operating current of the motor. The industrial computer is provided with a fitting algorithm, which fits the pressure gauge reading, the operating frequency and the operating current, and controls the opening of the proportional control valve according to the obtained fitting value, so that the air pressure supply is adjusted with the motor running state.
