Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The liquid asphalt addition control method provided in this application embodiment can be applied to, for example... Figure 1 The liquid asphalt addition control system shown includes a control computer 1, a PLC control module 2, a frequency converter 3, a motor 4, an asphalt pump 5, a manual valve 6, a flow meter 7, an electric valve 8, a bypass valve 9, a production system 10, a first cable 11, and a second cable 12. The control computer 1 is connected to the PLC control module 2, which is connected to the frequency converter 3 and the flow meter 7. The frequency converter 3 is connected to the motor 4, which is connected to the asphalt pump 5. The output terminal of the asphalt pump 5 is connected to the input terminal of the manual valve 6. The input end of the bypass valve 9 is connected to the power supply, the output end of the manual valve 6 is connected to the input end of the flow meter 7, the output end of the flow meter 7 is connected to the input end of the electric valve 8, the output end of the bypass valve 9 is connected to the input end of the electric valve 8, and the output end of the electric valve 8 is connected to the production system. The PLC control module 2 is connected to the frequency converter 3 via the first cable 11. The PLC control module 2 can also be connected to the frequency converter 3 via the second cable 12. The control computer 1 can be, but is not limited to, various desktop computers, laptops, etc. The production system 10 can be a production system 10 that produces products that require the addition of liquid asphalt (e.g., a carbon anode production system 10).

[0022] In one exemplary embodiment, such as Figure 2 As shown, a method for controlling the addition of liquid asphalt is provided. This method is executed by a computer device, specifically by a terminal or server alone, or by both a terminal and a server. In this embodiment, it includes steps 201 to 205. Wherein: Step 201: When a malfunction of the flow meter is detected, the manual valve is closed and the preset frequency of the frequency converter is determined.

[0023] As an optional implementation, step 201, determining the preset frequency of the frequency converter, may include: Obtain the historical operating frequency of the inverter 3; The average operating frequency of the inverter 3 is determined by calculating the historical operating frequencies. The average operating frequency is determined to be a preset frequency.

[0024] This implementation method, by acquiring the historical operating frequency of inverter 3 and calculating the average operating frequency as the preset frequency, fully considers the past operating conditions of inverter 3. This setting method based on actual operating data allows the preset frequency to better match the normal operating needs of the equipment, avoiding equipment instability caused by unreasonable frequency settings. In the control of liquid asphalt addition, it can ensure the stable operation of equipment such as asphalt pump 5, ensuring a stable supply of liquid asphalt, thereby providing strong support for the smooth operation of the production process and guaranteeing product quality.

[0025] As an optional implementation, before step 201, the following may also be included: Obtain the real-time asphalt flow rate collected by the flow meter 7; If the real-time asphalt flow rate is 0, proceed to steps 201 to 205. If the real-time asphalt flow rate is not 0, then the flow rate error between the real-time asphalt flow rate and the preset asphalt flow rate is determined. The adjustment frequency of the frequency converter 3 is determined based on the flow error; The frequency converter 3 is adjusted based on the adjustment frequency so that the frequency converter 3 adjusts the speed of the motor 4 and the asphalt pump 5.

[0026] In this implementation method, the real-time asphalt flow rate is first obtained. If it is 0, a fault procedure is followed to ensure timely response to abnormal situations. If it is not 0, the error between the real-time and preset asphalt flow rates is determined, and the frequency converter 3 is adjusted to regulate the speed of the motor 4 and the asphalt pump 5. This allows for dynamic and precise adjustment based on the actual flow rate, ensuring that the amount of liquid asphalt added better matches production needs. This avoids excessive flow deviation from affecting production, ensuring a stable and accurate supply of liquid asphalt to the production process, which helps maintain the continuity and stability of production, thereby guaranteeing product quality.

[0027] In this embodiment of the application, the formula for determining the flow error e(t) between the real-time asphalt flow rate and the preset asphalt flow rate can be: e(t) = SP - PV Where SP represents the preset asphalt flow rate and PV represents the real-time asphalt flow rate. The frequency of the inverter 3 can be continuously corrected based on the measured flow rate error, thereby correcting the speed of the motor 4 and the asphalt pump 5 to adjust the input flow rate of liquid asphalt until the flow rate error approaches zero.

[0028] Optionally, adjusting the frequency converter 3 based on the adjustment frequency to adjust the speed of the motor 4 and the asphalt pump 5 may include: The frequency converter 3 is adjusted based on the adjustment frequency to determine the current speed of the frequency converter 3; Determine the current motor speed and the current asphalt pump speed corresponding to the current rotational speed; The inverter 3 controls the speed of the motor 4 to the current motor speed; The motor 4 controls the rotation speed of the asphalt pump 5 to the current asphalt pump speed, so that liquid asphalt passes through the asphalt pump 5, the bypass valve 9, and the electric valve 8 to enter the production system 10.

[0029] In this implementation, the current speed of the frequency converter 3 is determined by adjusting the frequency, and the corresponding speeds of the motor 4 and asphalt pump 5 are further defined, forming a precise speed control chain. By precisely controlling the speed of the motor 4 through the frequency converter 3, and then precisely regulating the speed of the asphalt pump 5 through the motor 4, liquid asphalt can be stably and stably fed into the production system 10 along a specific path according to a pre-set schedule. In this way, the asphalt supply can be flexibly and precisely adjusted according to actual flow requirements, avoiding over- or under-supply, ensuring the stability and continuity of the production process, effectively improving production efficiency, and ultimately ensuring the quality of the final product.

[0030] Step 202: Determine the preset motor speed and preset asphalt pump speed corresponding to the preset frequency.

[0031] Step 203: The frequency of the frequency converter is controlled by the control computer using the PLC control module to the preset frequency.

[0032] As an optional implementation, step 203, whereby the control computer uses the PLC control module to control the frequency of the frequency converter to the preset frequency, can specifically be implemented as follows: The control computer 1 uses the PLC control module 2 to send the preset frequency to the frequency converter 3 via the first cable 11, so that the operating frequency of the frequency converter 3 is the preset frequency.

[0033] In this implementation method, the control computer 1, using the PLC control module 2, precisely sends a preset frequency to the frequency converter 3 via the first cable 11, enabling remote and efficient transmission of control commands. This wired transmission method is stable and reliable, effectively avoiding signal interference or loss, ensuring that the frequency converter 3 accurately receives the preset frequency information and operates accordingly. This guarantees precise control of the speeds of the motor 4 and the asphalt pump 5, ensuring a stable and accurate addition of liquid asphalt, making the production process more orderly and controllable, providing a solid guarantee for product quality stability, and improving the overall reliability and efficiency of production.

[0034] Step 204: Control the speed of the motor to the preset motor speed using the frequency converter.

[0035] Step 205: The speed of the asphalt pump is controlled by the motor to the preset asphalt pump speed, so that the liquid asphalt passes through the asphalt pump, the bypass valve and the electric valve to enter the production system.

[0036] For example, if flow meter 7 is not malfunctioning, liquid asphalt can be added in the following manner: 1) The control computer 1 sets the amount of asphalt to be added through the PLC control system; 2) The PLC control system monitors the real-time asphalt addition flow rate through flow meter 7; 3) The PLC control system calculates the real-time flow rate and controls the frequency of the inverter 3 via the second cable 12, thereby controlling the speed of the motor 4 and the asphalt pump 5. 4) Liquid asphalt is added to the production system 10 via asphalt pump 5 through manual valve 6, flow meter 7, and electric valve 8.

[0037] If flow meter 7 malfunctions, liquid asphalt can be added using the following method: 1) Add a control box to the control computer 1 to set the frequency of the inverter 3; 2) The frequency signal of the control computer 1 is connected to the frequency receiving signal of the frequency converter 3 through the PLC control system using the first cable 11. 3) The control computer 1 sets the frequency of the inverter 3 based on work experience through the PLC control system; 4) According to the set frequency, the PLC control system controls the frequency of the frequency converter 3 through the cable, and controls the speed of the motor 4 and the asphalt pump 5 (the speed of the motor 4 depends on the frequency of the frequency converter 3. The higher the frequency, the higher the speed, and the lower the frequency, the lower the speed; for example, the motor 4 has the highest speed when the frequency is 50HZ). 5) An appropriate amount of liquid asphalt is added to the production system 10 through bypass valve 9 and electric valve 8.

[0038] Implementing steps 201 to 205 avoids the problem of unstable liquid asphalt addition caused by flow meter 7 malfunction, ensuring the continuity and accuracy of liquid asphalt addition, thereby effectively guaranteeing the quality of produced carbon anodes. Furthermore, this application can also ensure the stable operation of equipment such as asphalt pump 5, ensuring a stable supply of liquid asphalt, thus providing strong support for the smooth operation of the production process and guaranteeing product quality. In addition, this application can maintain the continuity and stability of production, thereby guaranteeing product quality. Furthermore, this application can ensure the stability and continuity of the production process, effectively improving production efficiency, thereby ensuring the quality of the final product. In addition, this application can also ensure precise control of the speed of motor 4 and asphalt pump 5, making the liquid asphalt addition stable and accurate, and making the production process more orderly and controllable.

The determining unit 302 is used to determine the preset motor speed and the preset asphalt pump speed corresponding to the preset frequency; The first control unit 303 is used to control the frequency of the frequency converter 3 to the preset frequency via the control computer 1 and the PLC control module 2. The second control unit 304 is used to control the speed of the motor 4 to the preset motor speed through the frequency converter 3; The third control unit 305 is used to control the rotation speed of the asphalt pump 5 to the preset asphalt pump speed through the motor 4, so that the liquid asphalt passes through the asphalt pump 5, the bypass valve 9 and the electric valve 8 to enter the production system 10.

[0041] As an optional implementation, the method by which the shut-off unit 301 determines the preset frequency of the frequency converter 3 can be as follows: Obtain the historical operating frequency of the inverter 3; The average operating frequency of the inverter 3 is determined by calculating the historical operating frequencies.

This guarantees precise control of the speeds of the motor 4 and the asphalt pump 5, ensuring a stable and accurate addition of liquid asphalt, making the production process more orderly and controllable, providing a solid guarantee for product quality stability, and improving the overall reliability and efficiency of production.

[0045] As an optional implementation, the closing unit 301 is also used for: Obtain the real-time asphalt flow rate collected by the flow meter 7; If the real-time asphalt flow rate is 0, it is determined that the flow meter 7 has malfunctioned, and the shutdown unit 301 is triggered to shut down the manual valve 6 and determine the preset frequency of the frequency converter 3. If the real-time asphalt flow rate is not 0, then the flow rate error between the real-time asphalt flow rate and the preset asphalt flow rate is determined. The adjustment frequency of the frequency converter 3 is determined based on the flow error; The frequency converter 3 is adjusted based on the adjustment frequency so that the frequency converter 3 adjusts the speed of the motor 4 and the asphalt pump 5.
