The invention also relates to a control method adopting the weighing self-selecting dining equipment, which comprises the following steps:

step 1: the user takes the dinner plate 7 and binds the dinner plate 7 with the user;

in the invention, a user can be mainly identified through a face recognition technology or an NFC card reading technology and the like, then the dinner plate 7 is identified through interaction with an information receiving and sending mechanism in the dinner plate 7, the dinner plate 7 and the information receiving and sending mechanism are bound to a settlement position, and all behaviors generated by the dinner plate 7 are directly related to the user; in practice, the binding is theoretically the user's ID or other identification information and the identification information of the dinner plate 7.

Step 2: inputting required dishes and corresponding number of servings through an input unit based on the labels on the plurality of dish basins 2;

in the invention, in order to facilitate the operation, a label is generally arranged on the dish basin 2, a user confirms the dish according to the label when selecting the required dishes, and simultaneously inputs the number of copies, the number of copies is generally directly set by a shop, and different grams can be set as one copy based on the actual sales demand.

In the invention, after the dishes in any dish basin 2 are replaced, the background, such as the unit price of the dishes represented by the current label in the controller, should be changed in time.

And step 3: the container transportation unit moves to the position above the container storage unit corresponding to the dish, the container storage unit is opened, the container transportation unit takes the container 13, and the container transportation unit moves to the position above or at the side part of the dish;

and 4, step 4: the motor 22 rotates one or more times, and the dish picking unit puts the selected number of dishes into the container 13; the container transportation unit places a container 13 containing dishes on the bedplate 4;

in the invention, the container transportation unit is controlled to be started, the container storage unit is matched with the container to pick up the container 13, after the container 13 is sent to the vicinity of the dishes, the motor 22 drives the dish beating device 21 of the dish picking up unit to rotate for one time or more times, and the selected number of the dishes are placed in the container 13, wherein the number of the rotation times can be obtained through limited experiments and is generally within a certain range from top to bottom.

And 5: the dish weighing unit reads the weight of the dishes, and when the container 13 is taken down, the dishes and the corresponding weight are written into the signal receiving and transmitting mechanism of the dinner plate 7 corresponding to the current position;

in the invention, after the dish serving is finished, the container conveying unit places the container 13 on the bedplate 4 to read the accurate weight of the dishes, namely for example, the user selects 500g of dishes, but actually serves between 480g and 520g of dishes, the accurate gram weight is weighed at the moment, and the controller writes the accurate gram weight into the signal receiving and transmitting mechanism of the dinner plate 7 corresponding to the current position of the dish pushing area 5.

Step 6: and (4) after the dish taking is finished, directly reading the dish information and the weight settlement stored in the signal receiving and transmitting mechanism of the dinner plate 7.

In the invention, after the dish taking is finished, the settlement can be carried out based on all the recorded dish information and weight.

The method also ensures that the users who can hold a plurality of stations can order food, and has high rotation speed and high settlement efficiency.
