[0051] Embodiment two

[0052] Referring toFigure 11 The intelligent spit disc system with intelligent delivery and monitoring is shown, including an information acquisition module 2, an information scanning module 10, an information identification module, and a control module. Each module is connected through a wired and / or wireless network, and the control module is electrically connected with the first servo motor 7, the second servo motor 9, the double-head electric push rod 52, and the electric push rod 6 through a wire.

[0053] The information scanning module 10 is fixed on the lower surface of the support table 4, and is used to obtain the preset disc ID and the corresponding height value of the disc. The information scanning module 10 is integrated with an infrared scanner, a camera, and a height sensor, or uses a required hardware device;

[0054] The information acquisition module 2 is fixed on the surface of the main body case 1, and is used to obtain facial information. The information acquisition module 2 can be realized by using a camera;

[0055] The information identification module inputs the facial information into a preset information library for comparison, and calls the height value of the corresponding disc. It is realized based on a storage hardware such as a hard disk and a retrieval software or tool, such as a retrieval tool such as MySQL, Oracle Database, and Microsoft SQL Server;

[0056] The control module calculates and generates a disc taking instruction according to the height value. The first servo motor 7 drives the support table 4 to the corresponding position according to the disc taking instruction. After the disc is taken by the clamping jaw, the support table 4 is moved to the disc outlet 102, and then the disc is pushed out of the disc outlet 102 by the electric push rod 6. The control module is realized based on a PLC, a Raspberry Pi, a servo driver, or an encoder;

[0057] The information identification module and the control module are fixed in the main body case 1.

[0058] Specifically, the method for the information scanning module 10 to obtain the preset disc ID and the corresponding height value of the disc is as follows:

[0059] A two-dimensional code containing a unique number, i.e., a two-dimensional code containing a disc ID, is engraved on each disc;

[0060] After each disc is used for the first time, the unique number is written into a preset information library and is bound with the facial information of the user;

[0061] When the disc rack 3 containing the cleaned disc is placed into the main body case 1, the support table 4 with the information scanning module 10 moves from the head to the tail of the disc rack 3, so that the information scanning module 10 scans the two-dimensional codes one by one to obtain the corresponding height value of each disc ID, which is marked as H L , H L is an integer greater than or equal to 0, and H L represents the height value of the Lth disc.

[0062] Further, the control module generates the tray taking instruction method according to the height value, that is, obtaining the real-time height value of the turntable 4, marked as HS, HS is an integer greater than or equal to 0, and generating a real-time target value one according to HS L The expression of the real-time target value one ZB1 is: Wherein, P is the pitch of the first reciprocating screw rod 8, that is, the number of threads per unit length, for example, the pitch of the first reciprocating screw rod 8 is 2 mm, so that the screw rod moves 2 mm in the vertical direction per rotation of the first reciprocating screw rod, and P is obtained by a person skilled in the art according to the specification parameters of the first reciprocating screw rod 8;

[0063] M is the number of pulses required for one rotation of the first servo motor 7, for example, 2000 pulses are required for the first servo motor 7 to rotate a full circle, so that M is equal to 2000, and M is obtained by a person skilled in the art according to the model parameters of the first servo motor 7, the first servo motor 7 is executed according to ZB1, and ZB1 is the number of pulses executed by the first servo motor 7, and the turntable 4 is sent to the required tray taking position to take the tray;

[0064] After the tray is taken, a real-time target value two ZB2 is generated according to the expression: The first servo motor 7 is executed according to ZB2, and ZB2 is the number of pulses executed by the first servo motor 7, and the turntable 4 is sent to the tray outlet 102 to take the tray;

[0065] Considering that the first servo motor 7 rotates in different directions, the first reciprocating screw rod 8 can be reversed, that is, the turntable 4 can be controlled to ascend or descend, and And The absolute value is used in the expression, only positive numbers are generated, so the calculated real-time target value one and real-time target value two are integers greater than or equal to 0, so the control module controls the first servo motor 7 to be restrained, if H L -HS or HS-H L Greater than 0, the first servo motor 7 rotates forward;

[0066] If H L -HS or HS-H L Less than 0, the first servo motor 7 rotates reversely; in this way, the up and down movement of the turntable 4 can be realized, that is, the turntable 4 reaches the tray taking position to take the tray and then returns to the tray outlet 102 to take the tray.

[0067] Embodiment three

[0068] Referring to Figure 12 And Figure 13A pressure sensor is embedded in the surface of the tray 4, which is used to identify the pressure value on the surface of the tray 4. The pressure value is a value greater than or equal to 0. By identifying the pressure value on the surface of the tray 4, it can be determined whether there is a dinner plate on the surface of the tray 4. If the pressure value on the surface of the tray 4 is greater than or equal to a preset pressure value, a dinner plate is placed on the surface of the tray 4. If the pressure value on the surface of the tray 4 is less than the preset pressure value, no dinner plate is placed on the surface of the tray 4. The preset pressure value is the value obtained by the pressure sensor when a normal dinner plate is placed on the tray 4.

[0069] The intelligent tray dispensing system with intelligent delivery and monitoring also includes a tray conveying recognition module for determining the tray conveying status. The tray recognition module's identification methods include:

[0070] Get the real-time characteristic data of the plate conveyor, including pressure value, H L and HS;

[0071] The real-time feature data of the tray conveying is input into the trained tray conveying recognition model to obtain the tray conveying status, which is tray picking up, tray picking up completed, tray delivering, tray delivering completed, and tray discharging completed.

[0072] The training method for the tray delivery recognition model is:

[0073] Before training the tray delivery recognition model, k groups of historical feature data are collected, and the tray delivery status of the k groups of historical feature data are numerically labeled. When the tray delivery status is in the process of taking the tray, it is labeled as 1, when the tray delivery status is completed, it is labeled as 2, when the tray delivery status is in the process of delivering the tray, it is labeled as 3, when the tray delivery status is completed, it is labeled as 4, and when the tray delivery status is completed, it is labeled as 5; each group of historical feature data is used as the input of the machine learning model, and the machine learning model uses the predicted labeling of each group of historical feature data as the output, the actual labeling as the prediction target, and the minimization of the sum of the prediction accuracy of all labels as the training target; the calculation formula for the prediction accuracy is: k =(a k -w k ) 2 , where k is the number of the plate conveying characteristic data, z k is the prediction accuracy, a k is the predicted label value corresponding to the kth group of plate delivery feature data, w k The machine learning model is trained for the actual annotations corresponding to the k-th group of plate delivery feature data until the sum of the prediction accuracies reaches a stable state. The training is then stopped and the trained machine learning model is used as the plate delivery recognition model. The plate delivery recognition model is either a naive Bayes model or a support vector machine model.

[0074] Further, the control module determines whether to generate a control instruction based on the conveying state output by the dish conveying recognition model. The control instruction includes a primary instruction and a secondary instruction.

[0075] If the dish conveying state is the dish taking completion, the primary instruction is generated.

[0076] If the dish conveying state is the dish sending completion, the secondary instruction is generated.

[0077] If the dish conveying state is the dish taking, the dish sending or the dish taking end, no control instruction is generated.

[0078] Further, if the dish conveying state is the dish taking completion, i.e., the tray 4 reaches the specified position, the control module controls the double-end electric push rod 52 and the second servo motor 9 in the translation driving mechanism to work in sequence based on the primary instruction, to complete the action of clamping the dish and translating the dish to the tray 4. The working process control principle of the double-end electric push rod 52 and the second servo motor 9 is the same as that of the first servo motor 7, which will not be described here.

[0079] If the dish conveying state is the dish sending completion, i.e., the tray 4 reaches the dish outlet 102, the control module controls the electric push rod 6 to push the dish out of the dish outlet 102 through the push block 61 based on the secondary instruction. After the dish is sent out, the electric push rod 6 is reset.

[0080] The dish conveying recognition module stops working until the dish taking instruction is generated, and the dish conveying recognition module works again.

[0081] Embodiment Four

[0082] Referring to FIGS. 1, 2 and 3, Figure 7 and Figure 8 The shell 51 is in sliding connection with the tray 4, and two clamping jaws are arranged in the shell 51, and the clamping directions of the two clamping jaws are opposite. Correspondingly, two double-end electric push rods 52 are arranged, which are double-end electric push rod one and double-end electric push rod two. In this way, two dish racks 3 can be arranged in the main body case 1, which are arranged on both sides of the tray 4, so as to improve the utilization rate of the space in the main body case 1 and the storage amount of the dishes.

[0083] The control difference only needs to be scanned twice on the basis of embodiment two (when it is used again, i.e., after the dish rack 3 with the cleaned dishes is placed in the main body case 1, the information scanning module 10 is moved from the head to the tail of the dish rack 3 by the tray 4, and the information scanning module 10 scans the two-dimensional code one by one to obtain the corresponding height value of each dish ID.). The first time is to obtain the corresponding height value of each dish ID marked as R area, and the second time is to obtain the corresponding height value of each dish ID marked as L area.
