Currently, using infrared transmission and reception is relatively easy to implement and has a lower cost.

[0003] However, reflective infrared emission and reception detection schemes are easily affected by the environment, which can lead to misjudgments when identifying meter measurements. Summary of the Invention

[0010] A sixth aspect of the present invention is that a food processing machine is provided.

[0011] In view of the above, according to a first aspect of the present invention, the present invention provides a control method for a storage assembly, the storage assembly including a storage bin and a detection device, the detection device including a signal transmitter and a signal receiver, the signal transmitter being used to emit detection light to the storage bin, and the signal receiver being used to receive the detection light reflected by the storage bin, the control method including: acquiring a first detection signal from the signal receiver when the storage bin is not installed; acquiring a second detection signal from the signal receiver when the storage bin is installed and the storage bin stores material; and determining a calibration value based on the first detection signal and the second detection signal, so that the storage assembly can determine the storage information of the material in the storage bin based on the calibration value.

[0012] The technical solution of this application proposes a control method for storage components. By running this control method, the calibration value can be redefined. By redefined calibration value, the matching degree between the calibration value and the storage component can be improved, thereby improving the accuracy of material detection.

[0013] In addition, the control method for the storage component proposed in this application has the following additional technical features.

[0014] In the above technical solution, determining the calibration value based on the first detection signal and the second detection signal specifically includes: taking the first sum as the calibration value based on the fact that the first sum of the detection value corresponding to the second detection signal and the first value is less than the detection value corresponding to the first detection signal.

[0015] In this technical solution, a method for determining the calibration value is given. As described above, compared with the case where there is a storage bin for storing materials, the detection value corresponding to the detection signal will be higher when there is no storage bin for storing materials. Therefore, the detection value corresponding to the second detection signal can be used as the calibration value.

[0016] In any of the above technical solutions, a first reminder message is output based on the fact that the first sum is greater than or equal to the detection value corresponding to the first detection signal.

[0017] In this technical solution, by outputting a first reminder message, the user is informed that the current storage bin is not placed correctly, and then the placement of the storage bin is adjusted in a timely manner. In this process, the output first reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0018] In any of the above technical solutions, determining the calibration value based on the first detection signal and the second detection signal specifically includes: acquiring a third detection signal from the signal receiver when the storage bin is installed and the storage bin is not storing any material; determining a second sum of the detection value corresponding to the second detection signal and the second value based on the fact that the first sum of the detection value corresponding to the second detection signal and the first value is less than the detection value corresponding to the first detection signal; and determining the calibration value based on the detection value corresponding to the second detection signal and the detection value corresponding to the third detection signal based on the fact that the second sum is less than the detection value corresponding to the third detection signal.

This method is more complex than the calibration value determination method described above, but the determined calibration value is more reasonable. Therefore, it can improve the accuracy of meter measurement.

[0020] In any of the above technical solutions, determining the calibration value based on the detection value corresponding to the second detection signal and the detection value corresponding to the third detection signal specifically includes: determining the difference between the detection value corresponding to the second detection signal and the detection value corresponding to the third detection signal; determining the product of the difference and a preset proportional coefficient; and using the sum of the product of the detection value corresponding to the second detection signal and the preset proportional coefficient as the calibration value.

[0021] This technical solution provides a specific method for determining the calibration value. In this solution, the difference is determined to identify the difference in the detection signal when there is or is no material. Considering the impact of tolerance on the determination of the calibration value, a preset proportional coefficient is introduced. The difference is corrected using the preset proportional coefficient, and then the corrected difference, i.e., the product mentioned above, is used as compensation for the influence of the sidewall material on the detection value corresponding to the detection signal when there is material, thereby obtaining a calibration value that conforms to the actual use.

[0022] In any of the above technical solutions, a first reminder message is output based on the detection value corresponding to the third detection signal, where the second sum is greater than or equal to the detection value.

[0023] In this technical solution, by outputting a first reminder message, the user is informed that the current storage bin is not placed correctly, and then the placement of the storage bin is adjusted in a timely manner. In this process, the output first reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0024] In any of the above technical solutions, a second reminder message is output based on the fact that the first sum is greater than or equal to the detection value corresponding to the first detection signal.

[0025] In this technical solution, by outputting a second reminder message, the user is informed that the current storage bin is not placed correctly, and thus the placement of the storage bin is adjusted in a timely manner. In this process, the output second reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0026] In any of the above technical solutions, the method further includes: acquiring a fourth detection signal from a signal receiver; determining that the storage bin contains material based on the detection value corresponding to the fourth detection signal being less than or equal to a calibration value; and determining that the storage bin does not contain material based on the detection value corresponding to the fourth detection signal being greater than a calibration value.

[0027] This technical solution provides a method for determining the presence of materials based on recalibrated values. By using recalibrated values ​​to determine the presence of materials, the accuracy of the determination is improved.

[0028] In any of the above technical solutions, the number of detection devices is N, and the N detection devices are arranged at intervals along the height direction of the storage box. The control method further includes: acquiring the first detection signal output by the signal receiver under each detection device; and outputting a second reminder message based on the detection value corresponding to the N first detection signals being less than a third value; wherein, N is a positive integer greater than or equal to 2.

[0029] In the above technical solution, by limiting the selection of N detection devices, the accuracy of detection can be improved, and the probability of abnormal detection results caused by the malfunction of one or more detection devices can be avoided.

[0030] In the above technical solution, by limiting the layout of N detection devices, the accuracy of detection can be improved, and the probability of abnormal detection results caused by the malfunction of one or more detection devices can be avoided.

[0031] According to a second aspect of the present invention, a control device for a storage assembly is provided. The storage assembly includes a storage bin and a detection device. The detection device includes a signal transmitter and a signal receiver. The signal transmitter is used to emit detection light to the storage bin, and the signal receiver is used to receive the detection light reflected by the storage bin.

[0032] The technical solution of this application proposes a control device for a storage component. The storage component with the control device can realize the re-determination of calibration values. By re-determining the calibration values, the matching degree between the calibration values ​​and the storage component is improved, thereby improving the accuracy of material detection.

As described above, compared with the case where there is a storage bin for storing materials, the detection value corresponding to the detection signal will be higher when there is no storage bin for storing materials. Therefore, the detection value corresponding to the second detection signal can be used as the calibration value.

[0036] In the above technical solution, the determining unit is also used to: output a first reminder message based on the first sum being greater than or equal to the detection value corresponding to the first detection signal.

[0071] To better understand the above aspects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0072] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0073] Example 1

[0074] like Figure 1 As shown, according to an embodiment of the present invention, a control method for a storage assembly is provided. The storage assembly includes a storage bin and a detection device. The detection device includes a signal transmitter and a signal receiver. The signal transmitter is used to emit detection light into the storage bin, and the signal receiver is used to receive the detection light reflected by the storage bin. The control method includes:

[0075] Step 102: If the storage bin is not installed, acquire the first detection signal from the signal receiver;

[0076] Step 104: With the storage bin installed and the storage bin storing materials, acquire a second detection signal from the signal receiver;

[0077] Step 106: Determine the calibration value based on the first detection signal and the second detection signal, so that the storage component can determine the storage information of the material in the storage bin based on the calibration value.

[0078] The embodiments of this application propose a control method for a storage component. By running this control method, the calibration value can be redefined. By redefined calibration value, the matching degree between the calibration value and the storage component can be improved, thereby improving the accuracy of material detection.

[0079] Specifically, analysis of the reasons for the misjudgment revealed that the calibration value is given directly at the factory when the storage component leaves the factory, and it will not change based on the wear and tear of the storage component and / or changes in the usage environment.

[0080] However, with wear and tear, the light transmittance of the storage box will change. Similarly, the usage scenario will also change, and the calibration value given directly by the factory will no longer be applicable. When using the fixed calibration value to determine the amount of rice, misjudgment is very likely to occur.

[0081] Based on this, embodiments of this application acquire the detection signals of the signal receiver under different conditions in order to determine the calibration value based on the detection signals. In this process, the calibration value directly given at the factory can be recalibrated according to the actual use of the storage bin, thereby eliminating the impact of changes in the light transmittance of the storage bin and / or changes in the usage scenario on the accuracy of material detection.

[0082] Normally, without a storage bin, the signal receiver cannot receive the detection light emitted by the signal transmitter due to the absence of a storage bin. In this case, the first detection signal collected by the signal receiver is not affected by changes in the light transmittance of the storage bin or changes in the usage scenario.

[0083] After installing the storage bin containing the material, a second detection signal can be obtained by the signal receiver when the material is present. Due to the presence of the storage bin and the material, there will inevitably be a change between the detection value corresponding to the second detection signal and the detection value corresponding to the first detection signal. Therefore, the calibration value can be determined using the first and second detection signals.

[0084] In one embodiment, the signal transmitter may be an infrared transmitter, and the signal receiver used in conjunction with the signal transmitter may be an infrared receiver.

[0085] In one embodiment, the material stored in the storage bin can vary depending on the actual usage scenario. In the embodiments of this application, since the second detection value is collected when the storage bin contains material, the determined calibration value can be matched with the stored material, so as to improve the accuracy of the judgment when using the determined calibration value to determine whether material is stored.

[0086] At the same time, it can also eliminate the influence of assembly errors on the detection distance and angle deviation, the type of rice used by the user, the difference in light transmittance of the cabinet material, and the difference in sensitivity of the transmitting and receiving lights between different machines on the determination of whether there is stored material.

[0087] In any of the above embodiments, the material can be rice-based, such as rice, millet, corn, etc., or it can be beans, such as soybeans, red beans, mung beans, etc.

[0088] In this embodiment, the path of the detection light is specifically described when material is stored in the storage bin. Specifically, the storage bin has a translucent sidewall, which, when installed, faces the signal transmitter and receiver so that the detection light can propagate through the sidewall. A portion of the detection light passes through the sidewall into the storage bin and, reflected by the material, propagates through the sidewall to the signal receiver. Another portion of the detection light is reflected off the sidewall and propagates to the signal receiver.

[0089] In one embodiment, the intensity of the detection light received by the signal receiver is negatively correlated with the detection value corresponding to the output detection signal. Specifically, the more detection light the signal receiver receives, the greater the intensity of the received detection light, and the lower the detection value corresponding to the output detection signal. Conversely, the fewer detection light the signal receiver receives, the smaller the intensity of the received detection light, and the higher the detection value corresponding to the output detection signal. Based on this, the change between the first detection signal and the second detection signal can be determined, and the calibration value can be determined using this change.

[0090] In addition, the control method for the storage component proposed in this application has the following additional technical features.

[0091] In the above embodiments, determining the calibration value based on the first detection signal and the second detection signal specifically includes: taking the first sum as the calibration value based on the fact that the first sum of the detection value corresponding to the second detection signal and the first value is less than the detection value corresponding to the first detection signal.

[0092] In this embodiment, a scheme for determining the calibration value is given. As described above, compared with the case where there is a storage bin for storing materials, the detection value corresponding to the detection signal will be higher when there is no storage bin for storing materials. Therefore, the detection value corresponding to the second detection signal can be used as the calibration value.

[0093] Considering that there may be errors in the process of the signal receiver collecting and detecting light and the detection signal, a first value is introduced to take into account the impact of this error. The first value is then summed with the detection value corresponding to the second detection signal to obtain a first sum value, which is used as the calibration value.

[0094] In the above embodiments, by introducing a first value, the degree of matching between the calibration value and the actual use scenario is improved, thereby improving the accuracy of judging whether there is material and the amount of material.

[0095] In one embodiment, the first value can be selected according to actual usage needs, and its specific value will not be described in detail here.

[0096] In any of the above embodiments, a first reminder message is output based on the first sum being greater than or equal to the detection value corresponding to the first detection signal.

[0097] In this embodiment, by outputting a first reminder message, the user is informed that the current storage bin is not placed correctly, and thus the placement of the storage bin is adjusted in a timely manner. In this process, the output first reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0098] In one embodiment, the first reminder message may take the form of one or more of text, sound, and light, so as to select according to the actual use scenario of the storage component in order to meet the use needs of different scenarios.

[0099] In any of the above embodiments, determining the calibration value based on the first detection signal and the second detection signal specifically includes: when the storage bin is installed and the storage bin is not storing material, acquiring a third detection signal from the signal receiver; determining a second sum of the detection value corresponding to the second detection signal and the second value based on the fact that the first sum of the detection value corresponding to the second detection signal and the first value is less than the detection value corresponding to the first detection signal; and determining the calibration value based on the detection value corresponding to the second detection signal and the detection value corresponding to the third detection signal based on the fact that the second sum is less than the detection value corresponding to the third detection signal.

[0100] In this embodiment, another method for determining the calibration value is presented. This method is more complex than the method described above, but the determined calibration value is more reasonable. Therefore, it can improve the accuracy of meter measurement.

[0101] Specifically, the calibration value determination scheme described above is more applicable when the light transmittance of the side wall of the feed box is relatively good, that is, the light transmittance of the material forming the side wall is very high. If the light transmittance of the material forming the side wall is not very high, that is, the side wall is not completely transparent, the calibration value determined according to the calibration value determination scheme described above is prone to misjudgment of the meter quantity.

[0102] To overcome the above situation, the embodiments of this application propose another embodiment for determining the calibration value. Specifically, a third detection signal collected by a signal receiver is obtained under a storage bin containing unstored materials. If the first detection signal and the second detection signal satisfy the first condition, it is determined whether the second detection signal and the third detection signal satisfy the second condition. If they do, the calibration value is determined based on the second detection signal and the third detection signal.

[0103] In the above embodiments, as can be seen from the above text, the first condition is the same as the determination condition for determining the calibration value mentioned above. Therefore, the other calibration value determination scheme given in this embodiment is essentially based on the conditions for determining the calibration value mentioned above, with the addition of a determination condition (i.e., the second condition). The addition of the determination condition improves the adaptability of the calibration value to the actual use scenario, thereby improving the accuracy of the meter measurement.

[0104] Specifically, the determination of the calibration value is no longer related to the second detection signal, but also to the third detection signal. The third detection signal is the signal output by the signal receiver under the storage bin with no stored material. Therefore, the determined calibration value can eliminate the influence of the side wall material, thereby eliminating the influence of the rice bin material aging and bin surface wear on the calibration value, thus improving the adaptability of the calibration value to the actual use scenario.

[0105] In any of the above embodiments, determining the calibration value based on the detection value corresponding to the second detection signal and the detection value corresponding to the third detection signal specifically includes: determining the difference between the detection value corresponding to the second detection signal and the detection value corresponding to the third detection signal; determining the product of the difference and a preset proportional coefficient; and using the sum of the product of the detection value corresponding to the second detection signal and the preset proportional coefficient as the calibration value.

[0106] In this embodiment, a specific method for determining the calibration value is given. In this embodiment, the difference is determined to determine the difference in the detection signal when there is no material. Considering the influence of tolerance on the determination of the calibration value, a preset proportional coefficient is introduced. The difference is corrected by the preset proportional coefficient, and then the corrected difference, that is, the product mentioned above, is used as compensation for the influence of the sidewall material to the detection value corresponding to the detection signal when there is material, so as to obtain a calibration value that conforms to the actual use.

[0107] In the above embodiments, the preset proportional coefficient is selected according to the actual usage. In the embodiments of this application, the preset proportional coefficient is 0.5.

[0108] In any of the above embodiments, a first reminder message is output based on the detection value corresponding to the third detection signal, where the second sum is greater than or equal to the detection value.

[0109] In this embodiment, by outputting a first reminder message, the user is informed that the current storage bin is not placed correctly, and thus the placement of the storage bin is adjusted in a timely manner. In this process, the output first reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0110] In any of the above embodiments, a second reminder message is output based on the first sum being greater than or equal to the detection value corresponding to the first detection signal.

[0111] In this embodiment, by outputting a second reminder message, the user is informed that the current storage bin is not placed correctly, and thus the placement of the storage bin is adjusted in a timely manner. In this process, the output second reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0112] In one embodiment, the first reminder message may take the form of one or more of text, sound, and light, so as to select according to the actual use scenario of the storage component in order to meet the use needs of different scenarios.

[0113] In one embodiment, the difference between the first reminder message and the second reminder message is that the first reminder message is used to remind that the storage bin containing materials is not placed correctly, while the second reminder message is used to remind that the storage bin without materials is not placed correctly.

[0114] In any of the above embodiments, the method further includes: acquiring a fourth detection signal from a signal receiver; determining that the storage bin contains material based on the detection value corresponding to the fourth detection signal being less than or equal to a calibration value; and determining that the storage bin does not contain material based on the detection value corresponding to the fourth detection signal being greater than a calibration value.

[0115] In this embodiment, a scheme is provided to determine whether there is material based on the recalibrated calibration value. By using the recalibrated calibration value to determine the material, the accuracy of the determination is improved.

[0116] In any of the above embodiments, the number of detection devices is N, and the N detection devices are arranged at intervals along the height direction of the storage box. The control method further includes: acquiring the first detection signal output by the signal receiver under each detection device; and outputting a second reminder message based on the detection value corresponding to the N first detection signals being less than a third value; wherein, N is a positive integer greater than or equal to 2.

[0117] In this embodiment, a scheme for determining whether to place a storage bin is provided. In this embodiment, a second reminder message is output so that the user is aware that the storage bin is not placed correctly and can adjust the placement of the storage bin in a timely manner. In this process, the output second reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0118] In one embodiment, the first reminder message may take the form of one or more of text, sound, and light, so as to select according to the actual use scenario of the storage component in order to meet the use needs of different scenarios.

[0119] In one embodiment, the value of the third value is determined based on the actual usage scenario, and is not limited here.

[0120] In the above embodiments, by limiting the selection of N detection devices, the accuracy of detection is improved, and the probability of abnormal detection results due to the malfunction of one or more detection devices is avoided.

[0121] In the above embodiments, by limiting the layout of N detection devices, the accuracy of detection is improved, and the probability of abnormal detection results due to the malfunction of one or more detection devices is avoided.

[0122] In one embodiment, the distance between two adjacent detection devices is greater than a preset distance, wherein the preset distance is related to the parameters of the signal transmitter and the signal receiver in the detection device, specifically, it is related to the emission angle and emission intensity of the signal transmitter, and the reception angle and sensitivity of the signal receiver.

[0123] In one embodiment, such as Figure 2As shown, the present invention provides a control device 200 for a storage assembly. The storage assembly includes a storage bin and a detection device. The detection device includes a signal transmitter and a signal receiver. The signal transmitter is used to emit detection light to the storage bin, and the signal receiver is used to receive the detection light reflected by the storage bin. The control device includes: an acquisition unit 202, used to acquire a first detection signal from the signal receiver when the storage bin is not installed; and to acquire a second detection signal from the signal receiver when the storage bin is installed and the storage bin stores material; and a determination unit 204, used to determine a calibration value based on the first and second detection signals, so that the storage assembly can determine the storage information of the material in the storage bin based on the calibration value.

[0124] Embodiments of this application propose a control device for a storage component. The storage component having the control device can redetermine calibration values. By redetermining the calibration values, the matching degree between the calibration values ​​and the storage component is improved, thereby improving the accuracy of material detection.

[0125] Specifically, analysis of the reasons for the misjudgment revealed that the calibration value is given directly at the factory when the storage component leaves the factory, and it will not change based on the wear and tear of the storage component and / or changes in the usage environment.

[0126] However, with wear and tear, the light transmittance of the storage box will change. Similarly, the usage scenario will also change, and the calibration value given directly by the factory will no longer be applicable. When using the fixed calibration value to determine the amount of rice, misjudgment is very likely to occur.

[0127] Based on this, embodiments of this application acquire the detection signals of the signal receiver under different conditions in order to determine the calibration value based on the detection signals. In this process, the calibration value directly given at the factory can be recalibrated according to the actual use of the storage bin, thereby eliminating the impact of changes in the light transmittance of the storage bin and / or changes in the usage scenario on the accuracy of material detection.

[0128] Normally, without a storage bin, the signal receiver cannot receive the detection light emitted by the signal transmitter due to the absence of a storage bin. In this case, the first detection signal collected by the signal receiver is not affected by changes in the light transmittance of the storage bin or changes in the usage scenario.

[0129] After installing the storage bin containing the material, a second detection signal can be obtained by the signal receiver when the material is present. Due to the presence of the storage bin and the material, there will inevitably be a change between the detection value corresponding to the second detection signal and the detection value corresponding to the first detection signal. Therefore, the calibration value can be determined using the first and second detection signals.

[0130] In one embodiment, the signal transmitter may be an infrared transmitter, and the signal receiver used in conjunction with the signal transmitter may be an infrared receiver.

[0131] In one embodiment, the material stored in the storage bin can vary depending on the actual usage scenario. In the embodiments of this application, since the second detection value is collected when the storage bin contains material, the determined calibration value can be matched with the stored material, so as to improve the accuracy of the judgment when using the determined calibration value to determine whether material is stored.

[0132] At the same time, it can also eliminate the influence of assembly errors on the detection distance and angle deviation, the type of rice used by the user, the difference in light transmittance of the cabinet material, and the difference in sensitivity of the transmitting and receiving lights between different machines on the determination of whether there is stored material.

[0133] In any of the above embodiments, the material can be rice-based, such as rice, millet, corn, etc., or it can be beans, such as soybeans, red beans, mung beans, etc.

[0134] In this embodiment, the path of the detection light is specifically described when material is stored in the storage bin. Specifically, the storage bin has a translucent sidewall, which, when installed, faces the signal transmitter and receiver so that the detection light can propagate through the sidewall. A portion of the detection light passes through the sidewall into the storage bin and, reflected by the material, propagates through the sidewall to the signal receiver. Another portion of the detection light is reflected off the sidewall and propagates to the signal receiver.

[0135] In one embodiment, the intensity of the detection light received by the signal receiver is negatively correlated with the detection value corresponding to the output detection signal. Specifically, the more detection light the signal receiver receives, the greater the intensity of the received detection light, and the lower the detection value corresponding to the output detection signal. Conversely, the fewer detection light the signal receiver receives, the smaller the intensity of the received detection light, and the higher the detection value corresponding to the output detection signal. Based on this, the change between the first detection signal and the second detection signal can be determined, and the calibration value can be determined using this change.

[0136] In addition, the control device 200 for the storage component proposed in this application also has the following additional technical features.

[0137] In the above embodiment, the determining unit 204 is specifically used to: take the first sum as a calibration value based on the fact that the first sum of the detection value corresponding to the second detection signal and the first value is less than the detection value corresponding to the first detection signal.

[0138] In this embodiment, a scheme for determining the calibration value is given. As described above, compared with the case where there is a storage bin for storing materials, the detection value corresponding to the detection signal will be higher when there is no storage bin for storing materials. Therefore, the detection value corresponding to the second detection signal can be used as the calibration value.

[0139] Considering that there may be errors in the process of the signal receiver collecting and detecting light and the detection signal, a first value is introduced to take into account the impact of this error. The first value is then summed with the detection value corresponding to the second detection signal to obtain a first sum value, which is used as the calibration value.

[0140] In the above embodiments, by introducing a first value, the degree of matching between the calibration value and the actual use scenario is improved, thereby improving the accuracy of judging whether there is material and the amount of material.

[0141] In one embodiment, the first value can be selected according to actual usage needs, and its specific value will not be described in detail here.

[0142] In the above embodiment, the determining unit 204 is further configured to: output a first reminder message based on the first sum being greater than or equal to the detection value corresponding to the first detection signal.

[0143] In this embodiment, by outputting a first reminder message, the user is informed that the current storage bin is not placed correctly, and thus the placement of the storage bin is adjusted in a timely manner. In this process, the output first reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0144] In one embodiment, the first reminder message may take the form of one or more of text, sound, and light, so as to select according to the actual use scenario of the storage component in order to meet the use needs of different scenarios.

[0145] In the above embodiments, the determining unit 204 is specifically used for: acquiring a third detection signal from a signal receiver when the storage bin is installed and the storage bin is not storing any material; determining a second sum of the detection value corresponding to the second detection signal and the second value based on the fact that the first sum of the detection value corresponding to the second detection signal and the first value is less than the detection value corresponding to the first detection signal; and determining a calibration value based on the fact that the second sum is less than the detection value corresponding to the third detection signal and the detection value corresponding to the second detection signal and the third detection signal.

[0146] In this embodiment, another method for determining the calibration value is presented. This method is more complex than the method described above, but the determined calibration value is more reasonable. Therefore, it can improve the accuracy of meter measurement.

[0147] Specifically, the calibration value determination scheme described above is more applicable when the light transmittance of the side wall of the feed box is relatively good, that is, the light transmittance of the material forming the side wall is very high. If the light transmittance of the material forming the side wall is not very high, that is, the side wall is not completely transparent, the calibration value determined according to the calibration value determination scheme described above is prone to misjudgment of the meter quantity.

[0148] To overcome the above situation, the embodiments of this application propose another embodiment for determining the calibration value. Specifically, a third detection signal collected by a signal receiver is obtained under a storage bin containing unstored materials. If the first detection signal and the second detection signal satisfy the first condition, it is determined whether the second detection signal and the third detection signal satisfy the second condition. If they do, the calibration value is determined based on the second detection signal and the third detection signal.

[0149] In the above embodiments, as can be seen from the above text, the first condition is the same as the determination condition for determining the calibration value mentioned above. Therefore, the other calibration value determination scheme given in this embodiment is essentially based on the conditions for determining the calibration value mentioned above, with the addition of a determination condition (i.e., the second condition). The addition of the determination condition improves the adaptability of the calibration value to the actual use scenario, thereby improving the accuracy of the meter measurement.

[0150] Specifically, the determination of the calibration value is no longer related to the second detection signal, but also to the third detection signal. The third detection signal is the signal output by the signal receiver under the storage bin with no stored material. Therefore, the determined calibration value can eliminate the influence of the side wall material, thereby eliminating the influence of the rice bin material aging and bin surface wear on the calibration value, thus improving the adaptability of the calibration value to the actual use scenario.

[0151] In the above embodiments, the determining unit 204 is specifically used to: determine the difference between the detection value corresponding to the second detection signal and the detection value corresponding to the third detection signal; determine the product of the difference and a preset proportional coefficient; and use the sum of the product of the detection value corresponding to the second detection signal and the preset proportional coefficient as a calibration value.

[0152] In this embodiment, a specific method for determining the calibration value is given. In this embodiment, the difference is determined to determine the difference in the detection signal when there is no material. Considering the influence of tolerance on the determination of the calibration value, a preset proportional coefficient is introduced. The difference is corrected by the preset proportional coefficient, and then the corrected difference, that is, the product mentioned above, is used as compensation for the influence of the sidewall material to the detection value corresponding to the detection signal when there is material, so as to obtain a calibration value that conforms to the actual use.

[0153] In the above embodiments, the preset proportional coefficient is selected according to the actual usage. In the embodiments of this application, the preset proportional coefficient is 0.5.

[0154] In the above embodiment, the determining unit 204 is further configured to: output a first reminder message based on the detection value corresponding to the third detection signal that the second sum is greater than or equal to the detection value.

[0155] In this embodiment, by outputting a first reminder message, the user is informed that the current storage bin is not placed correctly, and thus the placement of the storage bin is adjusted in a timely manner. In this process, the output first reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0156] In the above embodiment, the determining unit 204 is further configured to: output a second reminder message based on the first sum being greater than or equal to the detection value corresponding to the first detection signal.

[0157] In this embodiment, by outputting a second reminder message, the user is informed that the current storage bin is not placed correctly, and thus the placement of the storage bin is adjusted in a timely manner. In this process, the output second reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0158] In one embodiment, the first reminder message may take the form of one or more of text, sound, and light, so as to select according to the actual use scenario of the storage component in order to meet the use needs of different scenarios.

[0159] In one embodiment, the difference between the first reminder message and the second reminder message is that the first reminder message is used to remind that the storage bin containing materials is not placed correctly, while the second reminder message is used to remind that the storage bin without materials is not placed correctly.

[0160] In the above embodiments, the determining unit 204 is further configured to: acquire a fourth detection signal from the signal receiver; determine that the storage bin contains material based on the detection value corresponding to the fourth detection signal being less than or equal to the calibration value; and determine that the storage bin does not contain material based on the detection value corresponding to the fourth detection signal being greater than the calibration value.

[0161] In this embodiment, a scheme is provided to determine whether there is material based on the recalibrated calibration value. By using the recalibrated calibration value to determine the material, the accuracy of the determination is improved.

[0162] In the above embodiment, the number of detection devices is N, and the N detection devices are arranged at intervals along the height direction of the storage box. The determining unit 204 is also used to: acquire the first detection signal output by the signal receiver under each detection device; and output a second reminder message based on the detection value corresponding to the N first detection signals being less than a third value; wherein, N is a positive integer greater than or equal to 2.

[0163] In this embodiment, a scheme for determining whether to place a storage bin is provided. In this embodiment, a second reminder message is output so that the user is aware that the storage bin is not placed correctly and can adjust the placement of the storage bin in a timely manner. In this process, the output second reminder message serves to guide the user's operation, thereby accurately and quickly determining the calibration value.

[0164] In one embodiment, the first reminder message may take the form of one or more of text, sound, and light, so as to select according to the actual use scenario of the storage component in order to meet the use needs of different scenarios.

[0165] In one embodiment, the value of the third value is determined based on the actual usage scenario, and is not limited here.

[0166] In the above embodiments, by limiting the selection of N detection devices, the accuracy of detection is improved, and the probability of abnormal detection results due to the malfunction of one or more detection devices is avoided.

[0167] In the above embodiments, by limiting the layout of N detection devices, the accuracy of detection is improved, and the probability of abnormal detection results due to the malfunction of one or more detection devices is avoided.

[0168] In one embodiment, the distance between two adjacent detection devices is greater than a preset distance, wherein the preset distance is related to the parameters of the signal transmitter and the signal receiver in the detection device, specifically, it is related to the emission angle and emission intensity of the signal transmitter, and the reception angle and sensitivity of the signal receiver.

[0169] In one embodiment, such as Figure 3 As shown, the present invention provides a control device 300 for a storage component, comprising: a controller 302 and a memory 304, wherein the memory 304 stores a program or instructions, and the controller 302 implements the steps of any of the methods in the first aspect when executing the program or instructions in the memory 304.

[0170] In one embodiment, the present invention provides a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of any of the methods in the first aspect.

[0171] In one embodiment, the present invention provides a storage component, including: a control device for any of the storage components described above; and / or a readable storage medium as described above.

[0172] In one embodiment, the signal transmitter and the signal receiver are spaced apart along a first direction, wherein the first direction is parallel or perpendicular to the height direction of the storage bin.

[0173] In one embodiment, such as Figure 4 and Figure 5 As shown, the layout scheme of N detection devices is given, as well as the layout scheme of detection device 404 when the first direction is perpendicular to the height direction of storage box 402, wherein, as Figure 5 As shown, the signal transmitter 4042 and the signal receiver 4044 are arranged at intervals at the same height in the storage bin 402.

[0174] like Figure 4 As shown, taking a rice bin as an example, a set of infrared transceivers (one infrared emitter and one infrared receiver, at the same horizontal level) are placed at different heights within the rice bin. The presence of an infrared receiver at a given location, and whether there is a sufficient signal, determines the rice storage height. Since rice grains are stacked differently and exhibit non-fully planar reflection, the reflected signal has a certain level range. Furthermore, the rice bin may not be made of fully infrared-transparent material, and the bin itself may also reflect some signal. Therefore, in practical applications, instead of directly using high or low voltage levels for judgment, AD voltage sampling may be employed.

[0175] Among them, such as Figure 6 As shown, a three-stage detection method is used, where N can be understood as 3. The signal transmitter 4042 is an infrared emitting lamp with a wavelength of 890nm to 980nm. For example, if a wavelength of 940nm is selected, the signal receiver 4044 is a sensor device that emits infrared light. When the infrared sensor receives infrared light of the above wavelength, current flows through the device. The greater the light intensity, the greater the current flows.

[0176] In this circuit, capacitor C is used for filtering; resistors R1 and R2 are current-limiting resistors used to adjust the emission intensity; and resistor R3 is a light intensity sampling resistor, which can adjust the level of the sampled signal under the same received light intensity. According to circuit principles, the greater the light intensity, the lower the sampled signal; under the same light intensity, the larger the sampling resistor, the lower the sampled signal; under the same conditions, the smaller the current-limiting resistor of the transmitting lamp, the greater the emitted light intensity; the more light received, the lower the sampled signal; when there is no reception, our sampled signal is the highest, which is the power supply level +5V.

[0177] like Figure 7As shown, the three-segment method yields three detection values, namely IR1, IR2, and IR3.

[0178] The following are methods for testing using the same calibration value:

[0179] Step 702, enter detection mode;

[0180] Step 704, boxless detection, IR1>190; IR2>190; IR3>190. If the judgment result is yes, proceed to step 706; if the judgment result is no, proceed to step 708.

[0181] Step 706, put it into the rice box;

[0182] Step 708, empty box defect;

[0183] Step 710: Detection of IR1 < 130; IR2 < 130; IR3 < 130. If the result is yes, end; if the result is no, proceed to step 712.

[0184] Step 712, output rice box malfunction.

[0185] The value 130 represents a threshold for determining whether there is rice. Different products may have different detection distances and angles due to assembly errors, differences in the type of rice used by the user, differences in the light transmittance of the cabinet material, and differences in the sensitivity of the transmitting and receiving lights between different machines. Using a single threshold for judgment on different machines can easily lead to misjudgments.

[0186] like Figure 7 As shown, if the presence or absence of rice is determined by a value of 130, and a machine in the product detects rice with a value of 143, it will be incorrectly judged as having no rice. For example... Figure 8 Based on the data and theoretical analysis shown, we can see that the value indicating whether a machine has rice is not a fixed number, but fluctuates within a certain range. Therefore, to better adapt the product to different parts and avoid misjudgments caused by differences in the rice type used by users, the following steps are performed: Figure 9 and Figure 10 The calibration.

[0187] like Figure 9 As shown, the calibration process includes:

[0188] Step 902, enter detection mode;

[0189] Step 904, boxless detection, IR1>190; IR2>190; IR3>190. If the judgment result is yes, proceed to step 906; if the judgment result is no, proceed to step 908.

[0190] Step 906: Record the unboxed AD value Vn and put it into the box with rice.

[0191] Step 908, empty box output is faulty;

[0192] Step 910: Sample and detect the AD value Vr.

[0193] Step 912, Vr+Cs<Vn, where Cs=20, if the judgment result is yes, proceed to step 914, if the judgment result is no, proceed to step 916;

[0194] Step 914: Write the threshold value;

[0195] Step 916, rice box output error.

[0196] Among them, the threshold for writing rice is equal to Vn+20, and the threshold is <Vr+Cs.

[0197] like Figure 10 As shown, the calibration process includes:

[0198] Step 1002: Enter detection mode;

[0199] Step 1004, boxless detection, IR1>190; IR2>190; IR3>190. If the judgment result is yes, proceed to step 1006; if the judgment result is no, proceed to step 1008.

[0200] Step 1006: Record the empty rice box AD value Vn and put it into an empty rice box;

[0201] Step 1008, Output: Empty box defect;

[0202] Step 1010: Sample empty meter and detect AD value Vs;

[0203] Step 1012, Vs+Cs<Vn, where Cs=0 to 50. If the judgment result is yes, proceed to step 1014; if the judgment result is no, proceed to step 1016.

[0204] Step 1014: Place the rice in a full rice box and sample the rice to detect the AD value Vr;

[0205] Step 1016, rice box malfunction;

[0206] Step 1018, Vr+Cr<Vn, where Cr=20, if the judgment result is yes, proceed to step 1020, if the judgment result is no, proceed to step 1022;

[0207] Step 1020: Write the threshold value;

[0208] Step 1022: Output rice box malfunction.

[0209] Among them, the written rice threshold is equal to (Vr + Vs) / 2.

[0210] Among them, first enter the calibration mode, record the AD value Vn sampled by the machine without the box at this time, and judge whether the Vn value meets the requirements. Since there is no occlusion reflection of the infrared transceiver lamp at this time, the receiving sensor theoretically has no infrared value. This is not affected by factors such as rice variety, emission lamp intensity, receiving lamp sensitivity, distance, box material, receiving angle, etc. The sampled AD should be close to the maximum value. Here, a fixed value can be taken for judgment, such as 190 in the example.

[0211] After the first step is confirmed to be OK, as Figure 9 shown, when the light transmittance of the box material is very high and the influence factor of the box material can be ignored, the box with rice can be directly put in. At this time, judge and record the sampled AD value Vr when the rice is full. Theoretically, Vr should be less than Vn. Considering the tolerance, the value of Vr + Cs should also be less than Vn + C. For example, C = 20. At this time, we can calibrate the threshold of this calibrated machine as Vr + Cs. That is to say, subsequently, this machine judges whether there is rice at this position according to whether it is less than the value of Vr + Cs. When the sampled value is less than or equal to Vr + Cs, it is judged that there is rice; when it is greater than Vr + Cs, it is judged that there is no rice.

[0212] In fact, the material of the rice box design may not be completely light-transmitting. If judged according to the Figure 9 logical algorithm, the value of Vr + Cs may be close to the value of Vn. If still judged according to the value of Vr + Cs, it is easy to misjudge an empty box as having rice. Therefore, according to the Figure 10 calibration method 2, the difference compared with method 1 is that before sampling the full-rice box Vr, the value Vs of the empty-rice box is also sampled. Theoretically, Vr + Cr < Vs, and Cr is the minimum interval of the design difference, for example, between 20 and 100. That is to say, Vs - Vr > 20. Considering the tolerance, this scheme does not limit a fixed value and uses the intermediate value, such as Vr + (Vs - Vr) / 2, which is equal to (Vr + Vs) / 2. That is to say, our calibration value is (Vr + Vs) / 2. Such a calibrated value is in the middle of the empty box and the full-rice box. Using the intermediate value is to consider that the actual detected Vr value may deviate due to the influence of different rice varieties and usage environment interference, increasing the compatibility and reliability of the system.

[0213] In addition to the above calibration of the product before leaving the factory, similarly, if the user finds that the detection is inaccurate during use, such as environmental interference light sources, aging of the material of the used rice box, different rice varieties used by the user, wear on the surface of the box, deviation of the placement position of the rice box after long-term use, aging attenuation of the infrared transceiver lamp, etc., affecting the recognition accuracy, the above calibration mode can be entered according to the above steps for adaptive calibration to be compatible with the actual use environment of the user.
