Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is, however, susceptible of embodiment in many other ways than those herein described and similar generalizations can be made by those skilled in the art without departing from the spirit of the application and the application is therefore not limited to the specific embodiments disclosed below.

The embodiment of the application provides a kitchen data processing method, a kitchen data processing device, electronic equipment and a storage medium. The following examples are described in detail.

The kitchen data processing method provided by the embodiment of the application can be applied to a system environment comprising a configuration management client and a server. A parameter set-related configuration for controlling kitchen video acquisition is received by a configuration management client. The parameter set indicates at least a capture period or capture frequency of kitchen video data of a merchant hitting the parameter set. In practice, the parameter set of a specific acquisition scheme can be designed according to the kitchen video acquisition requirements in different scenes. An exemplary parameter set design includes: global parameter set, configuration parameter set, merchant risk layering parameter set, peak period parameter set; the merchant can hit one or more parameter sets, and the parameter set for collecting kitchen video data is selected from the hit parameter sets according to a preset rule to be the video collection parameter set. The global parameter set is a global mode for controlling the acquisition period and/or controlling the frame extraction logic when acquiring the video, that is, the kitchen video can be acquired by a full-scale catering merchant accessing the system environment under the default of a platform deploying the system environment. By a configuration parameter set, it is understood a local parameter set for controlling the acquisition period and/or controlling the frame extraction logic when acquiring video for merchants hitting the corresponding configuration parameter set. The configuration parameter set may include a regional parameter set, a merchant list parameter set, and the like. For example, a regional parameter set is configured for a region, i.e. whether the merchant hits the configured regional parameter set is determined according to the geographic region to which the merchant belongs, and then a merchant list parameter set is configured, i.e. whether the merchant hits the configured merchant list parameter set is determined according to the merchant identifier or the merchant name. Each configured set of configuration parameters may individually configure the acquisition period or acquisition frequency. In a parameter set design mode, the priority of the configuration parameter set is higher than that of the global parameter set, and if the configuration parameter set is hit by a merchant, the configuration parameter set is used as a video acquisition parameter set for acquiring kitchen videos. The peak period parameter set is a parameter set according to the characteristics of the catering industry and aiming at a specified time period, for example, the parameter set is arranged at the peak period of food production such as lunch, dinner and the like, so that the sampling frequency can be increased, and videos of each order production are collected to provide a data basis for backtracking of food safety events; for another example, a parameter set is set for a period of night time in which the mice are not on peak, such as early morning. In one parameter set design manner, the priority of the peak period parameter set is higher than the priority of the configuration parameter set and the priority of the risk layering parameter set, that is, even if the user hits other configuration parameter sets and risk layering parameter sets in the peak period, the peak period parameter set is taken as the video acquisition parameter set, and if the user does not hit the other configuration parameter sets and risk layering parameter sets in the peak period, the parameter set with the higher priority or the parameter set with a shorter sampling period is taken as the video acquisition parameter set. The merchant risk layering parameter set is a parameter set corresponding to the layering for carrying out risk grading on merchants according to the risk grading of the merchants, and carrying out risk layering on the merchants according to the merchant risk layering of different risk grades. An exemplary merchant risk stratification includes: dividing merchants with food safety risks identified in three consecutive months into first risk classes, such as red risk merchants, setting the sampling period of a first risk class parameter set to be shorter, and collecting kitchen videos every 5 minutes; dividing merchants with food safety risks in two consecutive months into second risk classes such as orange risk merchants, and setting the sampling period of the second risk class parameter set to 15 minutes; merchants with food safety risk for nearly one month are classified as third risk classes, such as yellow risk merchants, and the sampling period of the third risk class parameter set is set to 30 minutes. For a risk-free merchant, other parameter sets, such as a configuration parameter set, a global parameter set, etc., are hit. Therefore, layering of merchants is achieved, different video acquisition periods are adopted, and effectiveness of video acquisition is improved. The timing task can automatically adjust the affiliated merchant risk level aiming at the merchant, and the merchant risk layering parameter set is combined, so that the acquisition frequency of the kitchen video is automatically improved or reduced, and the video acquisition efficiency is improved. Of course, the configuration management client also receives a specified risk stratification-related configuration for specifying a merchant risk level to which one or more merchants belong. For the merchant with the specified merchant risk level, the timing task for automatically adjusting the merchant risk level is not processed.

The server receives configuration information sent by the configuration management client, determines a video acquisition parameter set of kitchen video data of the businesses according to the configuration information in effect, acquires the kitchen video data of the businesses in a targeted manner according to an acquisition period or an acquisition frequency indicated by the video acquisition parameter set hit by each business, so as to obtain an effective video, identifies a security risk video containing an abnormal picture according to the acquired kitchen video data, associates the security risk video with the business information and stores the security risk video, is convenient for sending early warning prompt information to the businesses according to the security risk video, promotes the businesses to treat, and solves the kitchen food security problem.

The configuration management client can be a computer used for operation management and the like of a catering industry platform. The server may be a back-end server for processing kitchen video data of the merchant, etc.

Of course, a merchant client may also be included in the system environment. After the server side identifies the abnormal video, the related data and/or early warning prompt information of the abnormal video can be sent to the merchant client side to inform the merchant, so that the server side is convenient to take treatment measures in time, and the food safety problem is solved.

It should be noted that the above disclosed information is only used to aid in understanding the present application, and is not meant to constitute prior art known to those of ordinary skill in the art.

A kitchen data processing method provided in a first embodiment of the present application will be described with reference to fig. 1 to 3. The kitchen data processing method shown in fig. 1 comprises the following steps: step S101 to step S102.

Step S101, a first task for determining a video acquisition parameter set is started, wherein the first task is used for determining the video acquisition parameter set corresponding to a merchant for which kitchen video data are to be acquired.

Specifically, the kitchen environment is complex in constitution, the kitchen related space is divided into a plurality of key areas, the camera equipment is arranged, initial data are obtained by the camera equipment to serve as a kitchen video source, kitchen video data of each merchant are sampled from the kitchen video source, and food safety risks are further identified. In this embodiment, the video acquisition parameter set of the merchant controls the acquisition frequency of the kitchen video data of the merchant, so as to reduce the consumption of hardware resources as much as possible and reduce invalid video sampling data, and further detect the video data, such as pests, staff, manufacturing processes, early meal preparation areas, manufacturing areas, manufactured food packaging areas, and the like, which are acquired in the kitchen of the merchant and are related to food safety, comprehensively judge the food safety condition, and early warn against abnormal situations. Thereby improving the monitoring efficiency of food safety.

Specifically, the kitchen related space can be divided into a raw material acceptance area, a raw material storage area, a preliminary meal preparation area (including raw material cleaning, preparation and the like), a preparation area, a food preparation circulation area, a food packing area, a food preparation appliance and meal appliance cleaning and sterilizing area, a food preparation appliance and meal appliance storage area, a kitchen door area, a meal preparation room door area and other key areas; and recording the kitchen video source in the dimension of the commercial tenant or recording the kitchen video source in the dimension of key areas of different commercial tenants for acquiring the kitchen video data.

In this embodiment, in order to improve the effectiveness of the collected kitchen video data, different collection schemes may be formulated, and the collection of the kitchen video data of each merchant may be controlled by the parameter set corresponding to the collection scheme. The parameter set is indicative of at least a collection period. In one embodiment, a global parameter set that can be hit by each merchant is included, as well as a configuration parameter set and/or merchant risk stratification parameter set for controlling the acquisition frequency of a portion of the merchants. The global parameter set is a default hit parameter set of each merchant. The configuration parameter set is a parameter set hit by part of merchants, and can be further subdivided into a regional parameter set, a merchant list parameter set and the like. The merchant risk layering parameter set is a merchant risk grade layering of food security risks for merchants by a pointer, and different parameter sets are preset for merchants with different risk layering. Different collection parameter sets can be set for different merchant risk levels. In one embodiment, the system further comprises a peak period parameter set configured for peak periods, and the peak period parameter set is used for controlling the acquisition frequency and/or frame extraction logic of each merchant in the peak period. The parameter set may also indicate frame extraction logic for controlling a frame extraction processing mode when kitchen video data is collected for a merchant hitting the parameter set. The parameter set may also indicate a sampling duration. Of course, other parameter set designs may be used, all of which are within the scope of the present application. In one embodiment, the period of effectiveness of the parameter set may be specified when the parameter set is set. Therefore, kitchen video data are collected by merchants hitting the parameter set in different time periods through the collection period and/or frame extraction logic indicated by the parameter set. The above embodiments may be combined with each other without collision.

Specifically, examples of parameter set-related configurations are as follows: (1) For the global parameter set, camera data are collected every 2 hours, and all merchants hit the global parameter set by default. (2) The regional parameter set can be formulated according to the urban region, and can also be formulated according to different geographic regions of the city. (3) Parameter sets can be formulated according to business categories and/or business periods to which the merchant belongs, for example, corresponding configuration parameter sets are formulated for different business categories and business periods such as afternoon tea, breakfast, overnight and the like, so that corresponding acquisition period and/or frame extraction logic are adopted according to business characteristics of the merchant. In addition, the acquisition period (or acquisition frequency) may be configured separately for each parameter set, such as acquisition once every 4 hours, etc. The configuration mode of the acquisition period can be a mode of selection or input, for example, the configuration acquisition period is 5 minutes, 10 minutes, 15 minutes, 20 minutes, 30 minutes, 40 minutes, 45 minutes, 60 minutes, 90 minutes, 2 hours, 3 hours, 4 hours, 6 hours, 8 hours, and the like.

In this embodiment, the peak period parameter set may be determined according to a business class and/or a business period to which the merchant belongs. Also, the rush hour parameter set may be set for different critical areas. For example, regarding lunch periods (10:00-12:00 am), dinner periods (17:00-19:00) as production rush hour periods, a rush hour parameter set is set for the following key areas: the front meal preparation area (including raw material cleaning, preparation and the like), the manufacturing area, the food production circulation area, the food production packaging area, the food production tool and meal tool cleaning and disinfecting area, the food production tool and meal tool preservation area and the like are used for facilitating control of video monitoring and identification of the artificial health risks related to the manual production of food at a higher acquisition frequency. For another example, using the early morning hours (2:00-4:00 pm) as the rush hour time sets parameters for the following critical areas: raw material storage area, preliminary meal preparation area (including raw material cleaning, preparation, etc.), manufacturing area, thereby facilitating control of video monitoring and identification of environmental health risks related to pest emergence at higher acquisition frequencies.

In this embodiment, the relevant processing procedure for acquiring the kitchen video data is decoupled into a parameter set configuration task, a parameter set calculation task for determining a video acquisition parameter set, and a video acquisition task for acquiring the kitchen video data, so as to improve the processing flexibility and the processing efficiency. The parameter set configuration task is a task for executing a parameter set configuration command. Specifically, the parameter set configuration task is a front-end task, and is configured to receive configuration information of a parameter set input by an operation user using a configuration management client, store the configuration information after performing input validity check, and enable the configuration information to be effective, so that the first task obtains configuration information related to the parameter set to calculate an actual video acquisition parameter set of a merchant according to the configuration information. The parameter set configuration task specifically comprises the following steps: receiving configuration information aiming at a configuration parameter set and/or a risk layering parameter set, wherein the configuration information comprises sampling periods and/or parameter set priorities indicated by the corresponding parameter sets; checking whether the time length sequence of the sampling periods of different parameter sets accords with a preset standard sequence or not according to the configuration information, and if not, generating prompt information that the sampling periods are inconsistent with the preset standard sequence; and/or checking whether the parameter set priorities of different parameter sets accord with a preset priority order aiming at the configuration information, if not, generating prompt information of which the priorities are inconsistent with the preset priority order; and validating the configuration information in response to confirming the continued configuration for the prompt information. Of course, a merchant list provided by a third party and required to be monitored can be imported, and a merchant list parameter set is generated according to monitoring requirement information of merchants in the merchant list.

Specifically, the first task is a parameter set calculation task, the second task is a video acquisition task, and the first task and the second task are back-end tasks. In one embodiment, the method is processed in a T+1 mode, the first task calculates the video acquisition parameter set of each merchant according to the data of the previous natural day in the early morning, so that the total table comprising the video acquisition parameter set of each merchant can be calculated, and merchants with different acquisition periods can be classified and written into the message areas corresponding to the acquisition periods according to the acquisition periods. The second task may be executed in a unit time as a period (for example, executed by a timer every minute), and when an acquisition period is reached, the corresponding merchant is queried in the summary table or the message area corresponding to the acquisition period is polled to read the corresponding merchant, so as to obtain kitchen video data of the corresponding merchant. In other embodiments, the video acquisition task may also be decoupled into a second task and a third task. The second task is used for acquiring the commercial tenant to be acquired at the current time according to the video acquisition parameter set of each commercial tenant calculated by the first task, constructing a current acquisition message chain or writing the acquisition information of each commercial tenant into a message area corresponding to each acquisition period in a classified manner; and a third task, configured to read a message from the message chain or poll the corresponding message area according to different acquisition periods, access the kitchen video source for merchant information corresponding to the message, and extract a video frame from the kitchen video source according to frame extraction logic indicated by a video acquisition parameter set of the merchant, so as to obtain kitchen video data of sampling duration indicated by the video acquisition parameter set, and use the kitchen video data as a data analysis object for identifying food security risks. The different embodiments may be combined with each other without conflict.

In this embodiment, the method further includes layering the risk levels of the merchants, and setting corresponding risk layering parameter sets for the merchants of each risk layering. For example, if a merchant identifies food safety anomalies three months in succession, adding the merchant to a first risk level hierarchy, the hierarchical risk level hierarchy parameter set indicating a collection period of 5 minutes; if food safety abnormality is identified in two continuous months, adding the merchant into a second risk level hierarchy, wherein a risk hierarchy parameter set of the hierarchy indicates a collection period of 15 minutes; if a food safety anomaly was identified in the last month, the merchant is added to a second risk level hierarchy, the risk level hierarchy parameter set of which indicates a collection period of 30 minutes. Furthermore, the first task can be used for risk stratification of the merchant, and the timing task can be started to asynchronously perform risk stratification of the merchant, so that the merchant can automatically move among all risk layers based on historical risk data, and the method specifically comprises the following steps: starting a fourth task for adjusting the risk level of the merchant to which the merchant belongs; the fourth task is a timing task and is executed asynchronously with the first task; the fourth task comprises the steps of obtaining historical abnormal data of a merchant and determining a merchant risk level to which the merchant belongs according to the historical abnormal data; wherein the determining, according to the historical abnormal data, the merchant risk level to which the merchant belongs includes: if no abnormal data exists in a first specified number of continuous time periods, dividing the merchant into risk-free merchants; if there is anomalous data for each period within a first specified number of consecutive periods (e.g., 3 months in succession), then classifying the merchant as a first risk level (e.g., red risk stratification); if there is anomalous data within the first specified number of consecutive time periods and the anomalous data is within a second specified number of consecutive time periods (e.g., approximately 2 months), then classifying the merchant as a second risk level; if there is anomalous data within the first specified number of consecutive time periods and the anomalous data is within a third specified time period (e.g., approximately 1 month), then classifying the merchant as a third risk level; the first specified number of consecutive time periods includes the second specified number of consecutive time periods and the third specified time period; wherein the method further comprises: receiving a set of merchant risk levels for specified merchants, the specified merchants identified as specified risk merchants with specified risk levels; the fourth task includes eliminating the specified risk merchant when the merchant risk level to which the merchant belongs is adjusted so as to maintain the merchant risk level configured for the specified risk merchant. Thus, kitchen video data is conveniently collected for a specified risk merchant with a collection period of a specified merchant risk level.

Referring to fig. 2, a risk stratification process for adjusting a risk level of a merchant is shown, including: the risk level can be specified for the merchant, for example, the merchant is divided into a risk-free layer, a yellow risk layer, an orange risk layer and a red risk layer, wherein the risk-free layer, the yellow risk layer, the orange risk layer and the red risk layer respectively represent different risk levels, different risk degrees are reflected, and the risk-free, yellow, orange and red represent gradual increase of the risk degrees. The figure also includes: and automatically adjusting risk layering corresponding to the merchant according to the historical abnormal data (namely the historical risk data). S201, judging whether the continuous three months are abnormal, and if the continuous three months are abnormal, dividing the merchant into risk-free layering; if not, S202 is performed. S202, judging whether food safety risks occur in the last month, if so, dividing merchants into yellow risk stratification; if not, S203 is performed. S203, judging whether the food safety risk occurs in the next two months, if so, dividing the merchant into orange risk layers; if not, S204 is performed. S204, whether the food safety risk occurs in the last three months, if so, the merchant is classified into red risk stratification.
