Description

Technical Field

[0001] One or more embodiments of this specification relate to intelligent control technology, and in particular to a method, device, and electronic device for controlling the addition of tobacco flavoring. Background Art

[0002] The process of adding tobacco flavoring is generally as follows: The tobacco flavoring in the storage bottle is squeezed into the conduit under the action of an introduced gas source. When production blending is required, the controller controls the solenoid valve connected to the other end of the conduit to open, allowing the tobacco flavoring to enter the sampler through the solenoid valve and drip into the blending bottle from the sampler. After the weight sensor detects that the weight of the blending bottle reaches the target weight, the solenoid valve is closed to complete the addition process. However, in actual situations, due to the hysteresis error problem of the gravity sensor, the actual weight when the gravity sensor detects the target weight has not reached the target weight, and simply increasing the opening time of the solenoid valve easily leads to overweight addition. Currently, there is no method that can precisely control the addition process of tobacco flavoring. Summary of the Invention

[0010] Preferably, the method further includes: When the environmental information is updated, query the filling control information again.

[0024] See Figure 1 , Figure 1 is a schematic flow diagram of a method for controlling the addition of tobacco flavor provided by an embodiment of the present application. In the embodiment of the present application, the method includes: S101. After detecting the addition instruction, determine the flavor type information of the target tobacco flavor being added, and query the filling control information based on the flavor type information and environmental information.

[0025] Among them, the filling control information includes the single filling duration and the target opening amplitude of the solenoid valve. The single filling duration is the duration required for the target tobacco flavor to exactly fill the sampling tube. The environmental information includes temperature information, pressure information, and humidity information. The solenoid valve is provided at the inlet of the sampler.

[0026] The execution subject of the present application can be a controller.

[0027] In the embodiment of this specification, the schematic diagram of the principle of the addition process is as Figure 2As shown, when the staff generates a sample addition instruction through operations on the corresponding terminal, controls the solenoid valve to fully open, and starts the entire sample addition process, the controller will detect the sample addition instruction. The controller will parse the sample addition instruction to determine the flavor type information of the target tobacco flavor for the current sample addition process based on the additional information of the instruction. Tobacco flavors are fluids with a certain viscosity. Under the action of different environmental information such as temperature, pressure, and humidity, tobacco flavors with different flavor type information will exhibit different viscosities. In order to precisely control the entire sample addition process, the controller needs to determine the current viscosity of the target tobacco flavor. Specifically, the controller can query the data in the filling database to determine the filling control information corresponding to the flavor type information and environmental information, and use this filling control information to represent the viscosity of the target tobacco flavor under the current environmental information.

[0028] As an example, the staff can pre-adjust the environmental information in a test environment where the environmental information can be changed and collect the filling control information of various types of tobacco flavors under different environmental information. Finally, by summarizing these information, a mapping relationship between cigarette type information, environmental information, and filling control information is generated to construct a filling database. In the actual process, the controller only needs to query the filling database based on the cigarette type information and environmental information to obtain the corresponding filling control information. Among them, the reason why the filling control information also includes the target opening amplitude of the solenoid valve is that although a single filling duration can be obtained corresponding to different opening amplitudes of the solenoid valve, in some cases, the single filling duration may be too long, affecting the overall sample addition efficiency. Therefore, a filling duration range can be preset, and a set of filling control information is selected within this range, and this set of filling control information is used as the data in the filling database. In addition, when there are multiple sets of selectable filling control information within the preset range, any set can be selected as the data in the filling database.

[0029] S102. Determine the weight to be blended of the target tobacco flavor, and set a target weight based on the weight to be blended.

[0030] Among them, the target weight is less than the weight to be blended.

[0031] In the embodiments of this specification, the weight to be dispensed is the weight that is expected to be achieved after adding the target tobacco flavoring to the dispensing bottle theoretically. Due to the obvious hysteresis in the detected weight of the gravity sensor during continuous and large-scale sample addition, that is, when the elastic element is loaded, a moment that causes the bottom surface to move outward will inevitably be generated. When the load is removed, due to the existence of the bottom surface friction moment, the moment that causes the bottom surface to move back is less than the moment that causes the bottom surface to move outward during deformation, which blocks the recovery of the deformation of the elastic element and generates a hysteresis error. This makes it so that after continuously and largely adding samples until the detected weight of the gravity sensor reaches the weight to be dispensed, if the sample addition stops, after a period of time, the detected weight will decrease and be lower than the weight to be dispensed. For this reason, this application divides the entire sample addition process into two segments. The first segment is a conventional large-scale sample addition process, and the second segment is a process of adding samples one by one in small amounts. In this way, it is not easy to generate obvious hysteresis in the second segment, which can ensure the accuracy of the detected weight during the second segment of the sample addition process. To divide the sample addition process, the controller will set a target weight lower than the weight to be dispensed according to the weight to be dispensed. As long as the detected weight reaches the target weight, the second segment of the process of adding samples one by one in small amounts will be carried out. Among them, the setting of the target weight can be set according to a certain proportion of the weight to be dispensed (for example, 95% of the weight to be dispensed), or according to the manual experience of the hysteresis error, corresponding target weights are set for different weights to be dispensed, and a database storing the mapping relationship between the two is constructed. In actual situations, the corresponding target weight can be determined through querying the database.

[0032] In an implementable manner, setting the target weight based on the weight to be dispensed includes: Query the weight to be dispensed in a preset error database to obtain an error weight. The mapping relationship between the weight to be dispensed and the error weight is stored in the error database; Set the error weight as the target weight.

[0033] In the embodiments of this specification, the controller may pre-store an error database. According to the manual experience of the hysteresis error, corresponding error weights are set for different weights to be dispensed. The error weight may be the weight at which the detected weight drops from the weight to be dispensed under the influence of hysteresis. Finally, the controller will use the queried error weight as the target weight.

[0034] S103. Monitor the detected weight of the weight sensor. When the detected weight reaches the target weight, generate control information.

[0035] Among them, the control information is used to instruct the solenoid valve to open the valve amplitude to the target opening amplitude and maintain the single filling duration every time the first preset waiting duration elapses until the detected weight reaches the weight to be dispensed.

[0036] In the embodiments of this specification, the controller continuously monitors the detected weight of the weight sensor. When the detected weight reaches the target weight, the controller considers that the actual weight is almost reaching the weight to be formulated. At this time, the controller generates control information to control the solenoid valve for the next stage of the sample addition process. Under the control of the control information, the solenoid valve first enters the closed state, and then every time the first preset waiting duration (e.g., 20 s) elapses, it will open the valve according to the target opening amplitude and close after maintaining the single filling duration in the open state. Through the cycle of this process, the target tobacco flavor will be added to the formulation bottle in multiple small amounts. Each small addition will not cause obvious lag problems again, and during the multiple addition process, the lagging effect caused by the large amount of sample addition in the previous stage has been eliminated. When the final detected weight reaches the weight to be formulated, it means that the actual weight really reaches the weight to be formulated, and thus the control can be ended to complete the entire sample addition process flow.

[0037] Among them, as Figure 3 shown, the reason why this application selects the duration that the target tobacco flavor exactly fills the sampling tube as the single filling duration is considered that when the sampling tube of the sampler just touches the bottom of the formulation bottle, after the solenoid valve is closed, the tobacco flavor in the sampling tube of the sampler will be exactly filled, and at this time, the tobacco flavor in the sampling tube just contacts the tobacco flavor in the formulation bottle. At this time, due to the viscosity of the tobacco flavor, under the action of the negative pressure between the formulation bottle and the sampler, the tobacco flavor in the sampling tube will be completely squeezed into the formulation bottle. This can ensure that each newly added tobacco flavor is completely added to the formulation bottle, and at the same time, the tobacco flavor added each time is exactly the amount of the tobacco flavor with the volume of the sampling tube, which is convenient for accurately determining the quality of the tobacco flavor added each time. Among them, for the situation where negative pressure cannot be formed independently, the solenoid valve can be set to apply air pressure to the sampler after the solenoid valve is closed to actively form negative pressure.

[0038] In an implementable manner, the filling control information further includes the single filling mass, and the single filling mass is the mass of the target tobacco flavor that can exactly fill the sampling tube of the sampler; After generating the control information, it further includes: After the second preset waiting duration, determine the first weight difference between the weight to be formulated and the detected weight, and determine the remaining number of times based on the first weight difference and the single filling mass; Display the remaining number of times on the target interface.

[0039] In the embodiments of this specification, in the foregoing embodiments, only the filling duration for each time can be accurately controlled for each sample addition, but it is difficult for the staff waiting beside to intuitively understand how many more times of sample addition are needed to complete the sample addition process. Therefore, the filling control information may further include the single filling mass, which can also be tested in the test environment and then entered into the filling database for storage. Since it takes some time to eliminate the hysteresis error of the weight sensor, the controller will not immediately calculate the number of times when entering the stage of successive small sample additions. Instead, it waits for a second preset duration (e.g., 30 s). After the second preset duration, the controller considers that the error of the weight sensor has been eliminated at this time and the detected data is accurate enough. At this time, the controller will perform a division operation based on the first weight difference between the detected weight and the weight to be dispensed, and the single weight corresponding to the single filling mass, to obtain the remaining number of times. After determining the remaining number of times, the controller will display the remaining number of times on the target interface of the target terminal used by the staff, so that the staff can intuitively understand how many more times of sample addition the process will perform by observing the target interface.

[0040] In an implementable manner, after determining the remaining number of times based on the first weight difference and the single filling mass, it further includes: When the remaining number of times is not an integer, a cancellation message is generated, and the cancellation message is used to instruct the solenoid valve to stop working after completing the current filling; After a third preset waiting duration, determine the second weight difference between the weight to be dispensed and the detected weight, and determine the target sample addition tube among the candidate sample addition tubes based on the second weight difference. The target single filling mass corresponding to the target sample addition tube can be divided evenly by the second weight difference; Generate a replacement reminder message based on the target sample addition tube.

[0041] In the embodiments of this specification, in some cases, the first weight difference and the single filling mass cannot be divided evenly. This means that when adding samples successively according to the current single filling mass, it is impossible to accurately reach the weight to be prepared anyway. To avoid this situation, when the controller determines that the remaining number of times is not an integer, it will first generate a cancellation message to cancel the successive sample addition process controlled by the control information. Then, since the orifice tube of the sampler can be replaced and the sampler is generally equipped with multiple orifice tubes of different thicknesses, during the process of testing data in the test environment and constructing the filling database, the filling control information corresponding to different thicknesses of orifice tubes can also be tested and stored respectively. Considering that when canceling the operation, the sampler is already in the process of this sample addition, the cancellation message will not cancel the current ongoing sample addition process, but only the subsequent sample addition processes. Therefore, the controller will first wait for a third preset waiting duration (such as 20 s) until the current sample addition is completed, and then re-determine the second weight difference. By comparing the second weight difference with the single filling mass corresponding to each orifice tube, the target sampler orifice tube that can make the remaining number of times divisible can be determined, and the controller will generate a replacement reminder message with the target sampler orifice tube and send it to the target terminal of the staff to remind the staff to replace the orifice tube.

[0042] In an implementable manner, after generating the control information, it further includes: After the second preset waiting duration, obtain a captured image of the dispensing bottle, determine the liquid level height of the dispensing bottle based on the captured image, and calculate an estimated weight based on the liquid level height; Compare the estimated weight with the detected weight to generate an error judgment result.

[0043] In the embodiments of this specification, considering that as the service life increases and the equipment components age and are damaged, there is still a possibility of error in the detection result after eliminating the hysteresis error. After waiting for the second preset waiting duration to eliminate the hysteresis error, the controller will collect a captured image of the dispensing bottle through the camera and perform image recognition on the captured image to determine the liquid level height of the dispensing bottle. Based on parameters such as the liquid level height, the inner diameter width of the dispensing bottle, and the weight of the dispensing bottle itself, the controller can estimate the weight of the dispensing bottle at this time to obtain an estimated weight. Then, the controller will compare the estimated weight with the detected weight and generate an error judgment result. The staff can obtain this error judgment result to judge whether there is an abnormality in the detected value of the weight sensor and decide whether to perform corresponding control operations to interfere with the current sample addition process according to the judgment result.

[0044] In an implementable manner, the error judgment result includes a first error judgment result and a second error judgment result; Comparing the estimated weight and the detected weight to generate an error judgment result, including: Comparing the estimated weight and the detected weight; When a third weight difference between the estimated weight and the detected weight is less than a preset difference, generating a first error judgment result, where the first error judgment result is used to characterize that the weight sensor is detecting normally; When the third weight difference between the estimated weight and the detected weight is not less than the preset difference, generating a second error judgment result, where the second error judgment result is used to characterize that the weight sensor is detecting abnormally.

[0045] In the embodiments of the present specification, considering that the estimated weight is a predicted value and there will be certain errors itself, as long as the difference between the estimated weight and the detected weight is within the preset error, it is considered that the weight sensor is normal, otherwise it is considered that the weight sensor is abnormal. According to different comparison results, the controller will generate different error judgment results to send to the target terminal of the staff to inform the staff of the current situation of the weight sensor. The staff can stop the sample addition process in time after finding that the weight sensor is abnormal to avoid inaccurate weight to be blended in the blending bottle and affecting the quality of the products produced subsequently.

[0046] In an implementable manner, the method further includes: When the environmental information is updated, re-querying the filling control information.

[0047] In the embodiments of the present specification, during the sample addition process, the environmental information may change over time. Therefore, the controller will also continuously obtain the latest environmental information through temperature sensors, humidity sensors, etc. When the controller finds that the environmental information has changed and is updated, the controller will re-query the filling control information that matches the latest environmental information to ensure the accuracy of the sample addition process in real time.
