Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1, which is a schematic flow chart of a method for automatically adjusting and controlling a cavity environment of a self-service food packaging sales terminal according to a first embodiment of the present invention, the method is applied to a self-service food packaging sales terminal (i.e., a vending machine), and includes steps S101 to S103, where:

s101, reading label information of all dish packages currently stored in a cavity of the sales terminal when the closing of a box door of the sales terminal is detected; each dish package is provided with a tag capable of being read, and the tag information of each dish package comprises dish storage parameter information.

In this step, in a specific implementation, when it is detected that the sales terminal box door is closed, tag information of all dish packages currently stored in the cavity of the sales terminal can be read by the RFID reader-writer, and accordingly, a tag on each dish package, which is provided with tag information that can be read, is an RFID electronic tag. As can be appreciated, the use of the RFID tag facilitates writing, reading and modifying of the tag information of each dish package, and in this embodiment, the tag information of each dish package stored in the cavity of the sales terminal is at least written with a tag ID, a unit price of the dish and dish storage parameter information, where the tag ID is used as a unique identification code of each dish package, and the unit price of the dish is a sales price of each dish package. The dish storage parameter information comprises dish storage temperature and/or humidity parameter information. Preferably, the dish storage temperature information of each dish package is a temperature range; and storing humidity information of each dish packaged by the dishes in a humidity range.

As a preferable scheme, the label information of each dish package may further include a dish type, and for use as a sales terminal for selling general dish packages, the dish type may be different dish names or codes thereof, such as corn, cabbage, pumpkin, and the like; for a sales terminal that sells standard dish packages suitable for a cooker in coordination, the dish category may correspond to each recipe name or its code, such as hand-torn cabbage, Tuo chicken dices, braised pork in brown sauce, etc.

S102, determining the current optimal environmental parameters of the sales terminal cavity according to the dish storage parameter information in the label information of each dish package.

The dish storage parameter information comprises dish storage temperature and/or humidity parameter information, and the optimal environment parameter is an optimal temperature parameter and/or an optimal humidity parameter. In order to prolong the freshness keeping time of the dishes, the temperature and the humidity of the environment of the cavity of the sales terminal for storing the dishes need to meet the requirements of all the dishes placed in the cavity, in this embodiment, the optimal storage temperature and/or humidity parameter information meeting the storage requirement of the dishes is obtained by obtaining the storage temperature and/or humidity parameter information of the dishes packaged in the cavity of the sales terminal and calculating based on the storage temperature information of the dishes, and the temperature and/or the humidity of the cavity of the sales terminal is adjusted according to the optimal storage temperature and/or humidity parameter information.

In specific implementation, the optimal storage temperature parameter information can be obtained in the following way:

Preferably, the optimal temperature parameter is based on a maximum temperature value in the same temperature range in the dish storage temperature information of each dish package.

For example, the dish storing temperature information among the label information among the three packages of dishes currently stored in the cavity of the sales terminal (dish a1, dish a2, and dish A3) is read.

(1) When the storage temperature information of the three dishes packaged by the dishes is respectively dish A1: 1-9 ℃, dish A2: 3-10 ℃, dish A3: 4-12 ℃, and the preservation temperature information of the three dishes packaged by the dishes has the same temperature range: 4-9 deg.c, and thus the optimum temperature parameter may be determined as a temperature value in the temperature range of 4-9 deg.c. Preferably, the maximum temperature value in the temperature range of 4 ℃ to 9 ℃, that is, 9 ℃ is used as the optimal temperature parameter. Therefore, as an optimal scheme, the maximum temperature value in the same temperature range in the dish storage temperature information of each dish package is used as the optimal temperature parameter, so that the storage temperature requirement of dishes can be met, and the electric energy can be effectively saved.

(2) When the storage temperature information of the three dishes packaged by the dishes is respectively dish A1: 1-5 ℃, dish A2: 6-12 ℃, vegetable A3: 7-14 ℃, and the information of the preserving temperatures of the three dishes in the dish packages does not have the same temperature range, and in this time, the optimal temperature parameter is the maximum value which is equal to or less than the information of the preserving temperatures of the dishes in each dish package, namely 5 ℃.

Likewise, the best-to-preserve humidity parameter information may be obtained by:

for example, the dish keeping humidity information among the label information in the three dish packages (dish a1, dish a2, and dish A3) currently stored in the cavity of the sales terminal is read.

(1) When the preservation humidity information of the three dishes packaged by the dishes is respectively dish A1: 10% RH-60% RH, dish a 2: 20% RH-70% RH, dish a 3: 30% RH-80% RH, it can be seen that the humidity information of the three dishes packaged by the dish has the same humidity range: 30% RH to 60% RH, and thus, the optimal humidity parameter may be determined as a humidity value in one of the humidity ranges 30% RH to 60% RH. Preferably, the minimum humidity value of the humidity range of 30% RH to 60% RH, i.e., 30% RH, is used as the optimal humidity parameter. Therefore, as an optimal scheme, the minimum humidity value in the same humidity range in the dish storage humidity information of each dish package is used as an optimal humidity parameter, so that the dish storage humidity requirement can be met, and the electric energy can be effectively saved.

(2) When the preservation humidity information of the three dishes packaged by the dishes is respectively dish A1: 10% RH-40% RH, dish a 2: 50% RH-70% RH, vegetable A3: 50% RH-80% RH, it can be seen that the dish preservation humidity information of three dish packages does not have the same humidity range, and at this time, the optimal humidity parameter is the minimum value which is equal to or greater than the dish preservation humidity information of each dish package, namely 50% RH.

It can be understood that the dish described in this embodiment may include food materials such as meat, not only vegetables.

In addition, as a priority scheme of this embodiment, in order to further ensure the freshness of the dishes packaged in each dish stored in the cavity of the sales terminal, the storage temperature and/or humidity of the dishes packaged in the same cavity of the sales terminal may be set to be similar, that is, the same storage temperature range and/or the same storage humidity range exist, so as to effectively improve the freshness keeping time of the dish package.

S103, controlling the current environmental parameter of the sales terminal cavity to be the optimal environmental parameter.

Wherein, this step specifically includes:

When the method is specifically implemented, the current actual temperature and/or humidity of the cavity of the sales terminal can be detected in real time through the temperature sensor and/or the humidity sensor, if the current actual temperature and/or humidity of the cavity of the sales terminal is consistent with the calculated optimal temperature parameter and/or optimal humidity parameter, the current environment of the cavity of the sales terminal does not need to be adjusted, and otherwise, a corresponding environment parameter (temperature and/or humidity parameter) adjusting instruction needs to be generated to correspondingly adjust the current environment parameter of the cavity of the sales terminal. Specifically, the refrigeration module and/or the humidity regulator arranged in the sales terminal cavity can be used for carrying out corresponding adjustment.

As an optimization scheme of this embodiment, after the step S103, the method further includes the steps of:

During specific implementation, the adjusted current environmental parameters (temperature and/or humidity parameters) of the cavity of the sales terminal can be displayed through a display screen arranged on the outer surface of the sales terminal, so that users (including consumers and managers) can know the current temperature and/or humidity of the cavity of the sales terminal in time, and user experience is effectively improved.

Further, as a modification of this embodiment, the tag information of each dish package further includes a tag ID and a unit price of the dish, and after step S101, the method further includes the following steps:

And/or, after the step S101, the method further comprises the following steps:

It should be noted that the automatic cavity environment adjustment control method for the self-service vegetable packaging sale terminal provided in this embodiment is applicable to a self-service vegetable packaging sale terminal (i.e., a sale machine), and the self-service vegetable packaging sale terminal adopts a self-service sale mode of "selecting before payment", that is, after a currently used user (consumer) is authenticated, a sale terminal box door is opened for the user to select vegetable packages, and when the user finishes selecting and closing the sale terminal box door, all vegetable packaging labels read when the sale terminal box door is closed are compared with all vegetable packaging labels read when the sale terminal box door is opened, and the reduced labels are vegetable packages taken away by the user correspondingly, and a bill is generated according to the reduced label information to complete the charging operation for the user.

In the specific embodiment, the user may be authenticated in the following two ways:

the first method is as follows: the local (sales terminal) acquires the current user information and sends the current user information to the server for authentication;

the second method comprises the following steps: by attaching the two-dimension code image to the sales terminal, when a user wants to open the box door to obtain a dish packing box, the user can scan the two-dimension code image through a client (such as a mobile phone) to request to open the box door.

In addition, if the current user authentication is the administrator, the administrator can mend the dish packages or clean the overdue dish packages by opening the door of the sales terminal, and when the administrator completes closing the door of the sales terminal, the increased labels are the dish packages mended by the administrator, the decreased labels are the overdue dish packages cleaned by the administrator, and the information of the increased or decreased labels is used as the basis for the notification according to the comparison between all the dish package labels read when the door of the sales terminal is closed and all the dish package labels read when the door of the sales terminal is opened.

It can be understood that the self-service sales terminal can only be operated by one user at a time, that is, the self-service sales terminal can only identify and authenticate one user identity at a time, that is, during the period from the current user opening the door of the sales terminal to closing the door of the sales terminal, the sales terminal and the server refuse the request of other users for opening the sales terminal for use, that is, the server refuse the identity authentication request of other users to the sales terminal in the use state of the sales terminal, thereby ensuring that: 1. when the user is authenticated that the consumer uses the sales terminal, the reduced dish packages in the period from the opening to the closing of the door of the sales terminal can be ensured to be the dish packaging boxes taken away by the current consumer and serve as the basis for deduction; 2. when the user is authenticated as the administrator, the dish packages increased during the period from the opening to the closing of the door of the sales terminal can be guaranteed to be the dish packages supplemented by the current administrator, and the dish packages decreased during the period from the opening to the closing of the door of the sales terminal can be guaranteed to be the overdue dish packages cleaned by the current administrator and serve as the basis for the source of the notification.
