It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0035] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0036] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] Figure 1 is a block diagram showing a control device according to some embodiments of the present disclosure. Figure 1 As shown, the control device includes an RFID sensor 110, a feed start button 120, a PLC 130 and an RFID read-write controller 140. The RFID sensor 110, the feed start button 120 and the RFID read-write controller 140 are electrically connected to the PLC 130, respectively.

[0041] The RFID sensor 110 is used to generate a location signal (i.e., a vehicle location signal) when sensing the RFID chip of the mobile tank vehicle, and transmit the location signal to the PLC 130.

[0042] The feed start button 120 is used to send a feed start signal to the PLC 130 when being pressed.

[0043] PLC 130 is used to clear the information buffer (also called RFID information buffer) in the PLC after receiving the feeding start signal, and send an information reading signal to the RFID read-write controller 140 when the feeding start signal is received and the received in-place signal is continuously maintained (that is, the RFID sensor maintains the signal sensed by the RFID chip, that is, the RFID chip is always in a position close to the RFID sensor); it is also used to compare the material fragrance brand information of the RFID chip received from the RFID read-write controller 140 with the pre-stored material fragrance brand information, and control the execution of the feeding operation when the material fragrance brand information of the RFID chip is consistent with the pre-stored material fragrance brand information, and do not control the execution of the feeding operation (that is, do not execute the feeding operation) when the material fragrance brand information of the RFID chip is inconsistent with the pre-stored material fragrance brand information.

[0044] For example, the pre-stored brand information of the flavoring material includes: the brand information of the flavoring material issued by the production line or the brand information of the flavoring material already in the material tank.

[0045] In some embodiments, PLC 130 is used to compare the material fragrance brand information of the RFID chip with the material fragrance brand information issued by the production line when the material tank is empty. When the material fragrance brand information of the RFID chip is consistent with the material fragrance brand information issued by the production line, it is determined that the comparison is successful and the feeding operation is controlled to be executed. When the material fragrance brand information of the RFID chip is inconsistent with the material fragrance brand information issued by the production line, it is determined that the comparison fails and the feeding operation is not controlled to be executed. This achieves the purpose of controlling whether to execute the feeding operation when the material tank is empty.

[0046] In other embodiments, PLC 130 is used to compare the brand information of the incense on the RFID chip with the brand information of the incense in the material tank when there is incense in the material tank (i.e., the material tank is not empty). When the brand information of the incense on the RFID chip is consistent with the brand information of the incense in the material tank, it is determined that the comparison is successful and the feeding operation is controlled to be executed. When the brand information of the incense on the RFID chip is inconsistent with the brand information of the incense in the material tank, it is determined that the comparison fails and the feeding operation is not controlled to be executed. This achieves the purpose of controlling whether to execute the feeding operation when there is incense in the material tank.

[0047] The RFID read / write controller 140 is used to read the brand information of the material fragrance of the RFID chip after receiving the information reading signal, and transmit the brand information of the material fragrance of the RFID chip to the information buffer.

[0048] So far, a control device according to some embodiments of the present disclosure is provided. The control device includes: an RFID sensor, which is used to generate an in-place signal when sensing the RFID chip of the mobile tank trolley, and transmit the in-place signal to the programmable logic controller PLC; a feeding start button, which is used to send a feeding start signal to the PLC when it is pressed; the PLC, which is used to clear the information buffer in the PLC after receiving the feeding start signal, and send an information reading signal to the RFID read-write controller when the feeding start signal is received and the received in-place signal is continuously maintained; and the material fragrance brand information of the RFID chip received from the RFID read-write controller is compared with the pre-stored material fragrance brand information, and the material fragrance brand information of the RFID chip is controlled to execute the feeding operation when the material fragrance brand information of the RFID chip is consistent with the pre-stored material fragrance brand information, and the material fragrance brand information of the RFID chip is inconsistent with the pre-stored material fragrance brand information. The feeding operation is not controlled; and the RFID read-write controller is used to read the material fragrance brand information of the RFID chip after receiving the information reading signal, and transmit the material fragrance brand information of the RFID chip to the information buffer. This can improve the accuracy of the material fragrance brand reading and verification information.

[0049] The inventors of the present disclosure discovered that, in the related technology, when an RFID reading signal is generated but an RFID failure occurs, the information buffer of the PLC may not be refreshed successfully. At this time, the information buffer retains the brand information of the material fragrance read by the last RFID; even if the brand information of the material fragrance of the mobile tank is not the brand information of the material fragrance in the material tank at this time, because the brand retained in the information buffer is consistent with the brand in the material tank, adding materials to the material tank midway at this time is still successful. This situation violates the basic requirement that the brand of the material liquid in the mobile tank must be consistent with the brand of the material tank when replenishing the material liquid in the material tank midway, resulting in a failure.

[0050] In the above-mentioned control device of the embodiment of the present disclosure, by automatically clearing the information buffer in the PLC, it can be ensured that the information buffer is automatically cleared after the feeding from the mobile tank is completed, eliminating the quality risk of the brand information read by the last RFID in the information buffer. For example, when the same brand of materials is batched several times in succession, due to the capacity limitation of the material fragrance storage tank (i.e., the material tank), it is necessary to replenish the material fragrance in the mobile tank to the material tank multiple times. For such a situation, the above-mentioned control device improves the stability and accuracy of RFID information reading, and can prevent as much as possible the situation where important information such as the chip brand will not be updated to the PLC due to abnormalities in the RFID read-write controller, thereby ensuring the process quality of the flavoring and feeding process.

[0051] Figure 2 is a structural block diagram showing a control device according to some other embodiments of the present disclosure. Figure 2 As shown, the control device includes an RFID sensor 110 , a feed start button 120 , a PLC 130 and an RFID read-write controller 140 .

[0052] In some embodiments, Figure 2 As shown, the control device may further include a host computer 250. The host computer 250 is used to receive the material and fragrance brand information of the RFID chip from the PLC 130 and display the material and fragrance brand information of the RFID chip. Here, the host computer has a display, so the material and fragrance brand information of the RFID chip can be displayed.

[0053] In some embodiments, the PLC 130 can also be used to clear the information buffer when the material fragrance brand information of the RFID chip is inconsistent with the pre-stored material fragrance brand information, and send an alarm signal to the host computer 250. The host computer 250 can also be used to execute an alarm after receiving the alarm signal to prompt the brand verification error.

[0054] In some embodiments, the host computer 250 can also be used to send a production end command to the PLC 130. The PLC 130 can also be used to control the cleaning of the material tank and clear the information buffer after receiving the production end command. This facilitates the implementation of the next flavoring and adding process and ensures the accuracy of the brand information as much as possible.

[0055] In some embodiments, Figure 2 As shown, the control device may further include a feed valve 260. The feed valve 260 is disposed on the feed channel of the material tank. The feed valve 260 is used to open after receiving a feed valve opening signal. The PLC 130 is used to send a feed valve opening signal to the feed valve 260 when controlling the execution of the feed operation.

[0056] In some embodiments, Figure 2As shown, the control device may further include a pneumatic pump 270. The pneumatic pump 270 is a power source for extracting the material fragrance from the mobile tank into the material tank. The pneumatic pump 270 is used to start after receiving a pneumatic pump start signal to provide power for extracting the material fragrance from the mobile tank into the material tank. The PLC 130 is used to send a pneumatic pump start signal to the pneumatic pump 270 when controlling the execution of the feeding operation.

[0057] In the above embodiment, the feeding operation of extracting the material fragrance from the mobile tank into the material tank can be realized by PLC controlling the opening of the feeding valve and starting the pneumatic pump.

[0058] In some embodiments of the present disclosure, a flavoring feeder is also provided, the flavoring feeder comprising the control device as described above, for example Figure 1 or Figure 2 Controls shown.

[0059] Figure 3 is a flow chart showing a control method according to some embodiments of the present disclosure. Figure 3 As shown, the control method includes steps S302 to S314. The control method can be executed in a PLC.

[0060] In step S302, the arrival signal sent by the RFID sensor and the feed start signal sent by the feed start button are received.

[0061] In step S304, after receiving the feed start signal, the information buffer in the PLC is cleared.

[0062] In step S306, when the feed start signal is received and the received arrival signal is continuously maintained, an information reading signal is sent to the RFID read-write controller.

[0063] In step S308, the fragrance brand information of the RFID chip read by the RFID read-write controller is received.

[0064] In step S310, the fragrance brand information of the RFID chip is compared with the pre-stored fragrance brand information.

[0065] In step S312, the feeding operation is controlled to be executed when the material fragrance brand information of the RFID chip is consistent with the pre-stored material fragrance brand information.

[0066] In some embodiments, the control to execute the feeding operation includes: sending a feeding valve opening signal to the feeding valve to open the feeding valve; and sending a pneumatic pump starting signal to the pneumatic pump to start the pneumatic pump, so that the pneumatic pump provides power to extract the material fragrance from the mobile tank into the material tank.

[0067] In step S314, when the material fragrance brand information of the RFID chip is inconsistent with the pre-stored material fragrance brand information, the feeding operation is not controlled to be executed.

[0068] In some embodiments, the control method may further include: clearing the information buffer when the material fragrance brand information of the RFID chip is inconsistent with the pre-stored material fragrance brand information, and sending an alarm signal to the host computer so that the host computer executes an alarm to prompt a brand verification error.

[0069] So far, a control method according to some embodiments of the present disclosure is provided. The method improves the stability and accuracy of RFID information reading, can prevent as much as possible the situation where important information such as chip brand number will not be updated to PLC due to abnormality of RFID read / write controller, etc., and ensure the process quality of flavoring and feeding process.

[0070] In some embodiments, the pre-stored flavor brand information includes: the flavor brand information issued by the production line or the flavor brand information already in the flavor tank.

[0071] In some embodiments, comparing the material fragrance brand information of the RFID chip with the pre-stored material fragrance brand information includes: when the material tank is empty, comparing the material fragrance brand information of the RFID chip with the material fragrance brand information issued by the production line; wherein, when the material fragrance brand information of the RFID chip is consistent with the material fragrance brand information issued by the production line, it is determined that the comparison is successful and the feeding operation is controlled to be executed; when the material fragrance brand information of the RFID chip is inconsistent with the material fragrance brand information issued by the production line, it is determined that the comparison fails and the feeding operation is not controlled to be executed.

[0072] In other embodiments, comparing the brand information of the material fragrance on the RFID chip with the pre-stored brand information of the material fragrance includes: when there is material fragrance in the material tank, comparing the brand information of the material fragrance on the RFID chip with the brand information of the material fragrance already in the material tank; wherein, when the brand information of the material fragrance on the RFID chip is consistent with the brand information of the material fragrance already in the material tank, it is determined that the comparison is successful and the feeding operation is controlled to be executed; when the brand information of the material fragrance on the RFID chip is inconsistent with the brand information of the material fragrance already in the material tank, it is determined that the comparison fails and the feeding operation is not controlled to be executed.

[0073] In some embodiments, the control method may further include: sending the brand information of the material and fragrance of the RFID chip to the host computer so that the host computer displays the brand information of the material and fragrance of the RFID chip.

[0074] In some embodiments, the control method may further include: after receiving a production end command from a host computer, controlling the execution of tank cleaning and clearing an information buffer.

[0075] Figure 4 FIG. 1 is a flow chart showing a control method according to other embodiments of the present disclosure. Figure 4 As shown, the control method may include S402 to S418. The control method may be executed in a PLC.

[0076] In step S402, the arrival signal sent by the RFID sensor and the feed start signal sent by the feed start button are received.

[0077] For example, when the chip of the mobile tank trolley is close to the RFID sensor, the RFID sensor automatically generates an arrival signal when it senses the RFID chip and transmits it to the PLC, which receives the arrival signal.

[0078] When the feed start button is pressed, a feed start signal is sent to the PLC, and the PLC receives the feed start signal.

[0079] In step S404, after receiving the feed start signal, the information buffer in the PLC is cleared.

[0080] In step S406, when the feed start signal is received and the received arrival signal is continuously maintained, an information reading signal is sent to the RFID read-write controller.

[0081] In the above steps, the arrival of the trolley and the start of feeding of the barrel are determined by receiving the arrival signal and the feeding start signal. When both conditions are met, the information reading signal is triggered.

[0082] For example, it can be determined whether the trolley arrival signal is 1. If so, it is determined whether the feed start button is pressed, otherwise the program returns to the beginning. If it is determined that the feed start button is pressed, the information reading signal is triggered, otherwise the program returns to the beginning.

[0083] For another example, the process of PLC triggering information reading signal is as follows:

[0084] First read the process

[0085] DB1.DBB 116: "APPL0_DB".CMDBUF[3].CMD is set to B#16#70;

[0086] DB1.DBW4: "APPL0_DB".CMDSEL is set to 3; DB1.DBW140: "APPL0_DB".CMDBUF[3].Length is set to "write carrier data length", which is usually 70.

[0087] Then change DB1.DBX 0.0: "APPL0_DB".EXECUTE from 0 to 1 to trigger it once.

[0088] In step S408, the fragrance brand information of the RFID chip read by the RFID read-write controller is received.

[0089] After receiving the material flavor brand information from the RFID chip, the PLC can also write the brand code (i.e. the material flavor brand information from the RFID chip) and other data in the information buffer area into the upper computer of the flavoring and feeding machine for screen display.

[0090] In step S410, when the material tank is empty, it is determined whether the material fragrance brand information of the RFID chip is consistent with the material fragrance brand information issued by the production line. If yes, the process proceeds to step S414; otherwise, the process proceeds to step S416.

[0091] Here, the host computer system can transmit the material brand information to the production line, and the production line sends it to the PLC and stores it in the PLC as a basis for comparison with the material brand information of the RFID chip.

[0092] In step S412, if there is incense in the material tank, it is determined whether the brand information of the incense on the RFID chip is consistent with the brand information of the incense in the material tank. If yes, the process proceeds to step S414; otherwise, the process proceeds to step S416.

[0093] In step S414, the comparison is successful, feeding is allowed, the feeding valve is controlled to open, and the pneumatic pump is operated.

[0094] In step S416, if the comparison fails, the information buffer is cleared, and a brand verification error alarm is generated on the screen of the host computer.

[0095] In step S418, after receiving the production end command from the host computer, the control executes the material tank cleaning and clears the information buffer.

[0096] For example, when the production of the material tank is completed, the operator sends a production end command through the host computer. After receiving the production end command, the PLC controls the cleaning equipment to clean the material tank. After the cleaning is completed, the PLC automatically clears the information buffer.

[0097] So far, control methods according to other embodiments of the present disclosure are provided. The control method realizes the application of the RFID information reading, writing and verification method of the flavoring and feeding system, improves the stability and accuracy of RFID information reading, and tries to prevent the situation where important information such as chip brand number will not be updated to the PLC due to abnormality of the RFID read-write controller, thereby ensuring the process quality of the flavoring and feeding process.
