Description
Technical Field
The invention relates to the technical field of cold chain monitoring, in particular to a closed-loop cold chain monitoring method.
Background
The cold chain refers to a special supply chain system which is used for ensuring the food safety, biological safety and drug safety of products, and reduces loss, prevents pollution and deterioration because each link of the products is always in a special low-temperature environment required by the products in the processes of processing, storing, transporting, distributing, retailing and using after some food raw materials, processed foods or semi-finished products, special biological products and drugs are purchased, processed and put out a fire.
In order to ensure the quality of cold chain products and food, the existing cold chain scheme mostly adopts a one-object-one-code monitoring method, for example, an agricultural product one-object-one-code traceability system, a unique product code is given to each agricultural product, information such as a production place, transportation vehicle information, storage temperature and the like of the agricultural product is input through code scanning in the production, processing, transportation, sale and other links of the agricultural product, an information traceability record corresponding to the agricultural product is formed, and the corresponding code scanning information input record can be traced from a database as long as the unique product code of the agricultural product is scanned subsequently. For another example, a cold chain transport effectiveness monitoring system and method provided by publication number CN202011032708.7 specifically provide a product effectiveness monitoring system, when in use, a user can obtain factory production information of a secondary vaccine by reading the content of the RFID chip of the vaccine through a mobile phone, and whether a temperature is out of control before use, and the essence of the product also obtains traceable information formed in each cold chain link and recorded in the RFID chip carried by the vaccine, which is consistent with the tracing principle of one-object-one-code agricultural products.
The existing cold chain method has the following technical problems:
traceable information is formed after scanning the unique code attached to the product through cold chain personnel and inputting the information, and cold chain information input is probably fake due to the lack of effective monitoring means for the cold chain personnel when the cold chain personnel input the cold chain information. For example, in a certain cold chain link, a qualified cold chain person a should control the cold chain environment and input cold chain information, but actually, a non-qualified cold chain person B replaces a to complete the work, so that the effective control on the cold chain behavior is lost in the cold chain link. For another example, the allowable cold chain temperature of a product in the cold chain link 1 is 0-5 ℃, but the actual cold chain temperature is 10 ℃ which is not in compliance, and in order to avoid being penalized, cold chain personnel in the link records 3 ℃ to replace 10 ℃ of the real environment, which also causes the cold chain monitoring of the cold chain link to be invalid.

The closed-loop cold chain monitoring method provided by the embodiment of the invention, as shown in fig. 1, comprises the following steps:
s1, a cold chain task is established through a cold chain client comprehensive service platform, and the cold chain task comprises a plurality of cold chain subtasks respectively corresponding to different cold chain links of the same cold chain event; the cold chain typically includes the following cold chain links: freezing process, frozen storage, refrigerated transport and distribution, frozen/refrigerated sales, and the like. The cold chain logistics generally refers to a system project of ensuring the quality and performance of refrigerated and frozen goods in production, storage, transportation and sale and in all links before consumption under a specified low-temperature environment. A cold chain event includes at least one cold chain link, for example, cold chain event 1 includes a cold chain link of freezing process, cold chain event 2 includes a cold chain link of freezing process and freezing storage, and cold chain event 3 includes a cold chain link of freezing storage, freezing transportation and distribution 2, etc. The cold chain event comprises which cold chain links are related to the type of cold chain goods, for example, for the cold chain of tuna, a total of 4 cold chain links involving freezing processing, freezing storage, refrigerated transportation and distribution, and freezing sale are required, and then the cold chain event comprises the 4 cold chain links; and for the cold chain of vegetables and fruits, if only refrigerated transportation and distribution and refrigerated sales are involved, the cold chain event only comprises two cold chain links.
The task content of the cold chain subtask includes unique equipment code information (equipment information is embedded in a two-dimensional code or a one-dimensional bar code, and the equipment information is a unique serial number of the equipment) of the specified cold chain equipment, identity information of cold chain personnel executing the cold chain subtask, an allowed temperature range and/or an allowed humidity range of the specified cold chain equipment, and a task unique code of the cold chain subtask. The task content is, for example: the tuna is processed by processing equipment with a unique equipment code of xxxxxxx001 in a freezing processing link, and is frozen by freezing equipment with a unique equipment code of yyyyyyyyy001, the freezing temperature of the tuna in the freezing processing cold chain link is required to reach below a ℃, and the freezing processing is required to be operated by a specified certain cold chain person or a certain cold chain team; the refrigeration temperature of the vegetables and fruits in the cold chain link of refrigeration transportation and distribution is required to be b-c ℃, the humidity is between d-e, and the refrigeration transportation and distribution are required to be specified certain cold chain personnel.
S2, issuing each cold chain subtask to a cold chain person working in a corresponding cold chain link;
s3, each cold chain worker receives the issued cold chain subtask through a client running on the intelligent terminal, scans the unique equipment code attached to the cold chain equipment specified in the task through a code scanning function embedded in the receiving page, and then the client forms the cold chain information of the cold chain link according to a first strategy and binds the cold chain information and the corresponding cold chain subtask to form binding information (the binding information also comprises time for forming the binding information, the time for forming the binding information is defined as second time for distinguishing the time for forming the cold chain information, and the time for forming the cold chain information is defined as first time) and stores the binding information;
the method for forming the cold chain information of the cold chain link by the client according to the first strategy comprises the following steps:
s31, after a cold chain person scans the unique equipment code of the cold chain equipment, the client sends a cold chain environment information acquisition instruction to the cold chain equipment, and simultaneously activates a monitoring device special for monitoring the scanned cold chain equipment;
s32, after receiving the acquisition instruction, the cold chain equipment sends self cold chain environment information (including the current cold chain temperature and/or cold chain humidity of the cold chain equipment) to the platform; the activated monitoring device sends the continuously monitored real-time video stream to the platform;
s33, the platform acquires identity information of login personnel identified by the intelligent terminal when the cold chain personnel log in the client;
and S34, the platform forms the cold chain environment information, the real-time video stream, the identity information of the login personnel identified in the step S33 and the scanned unique equipment code which are uploaded after the unique equipment code is scanned by the received cold chain personnel into cold chain information corresponding to the cold chain link in a cold chain event. Each piece of cold chain information also includes a first time at which the cold chain information was formed.
As shown in fig. 1, after the binding information is formed, the closed-loop cold chain monitoring method proceeds to the following steps:
s4, the platform takes the unique equipment code of the cold chain equipment in the corresponding cold chain link scanned by the quality testing personnel as an instruction, and retrieves the quality testing data through a second strategy;
the method for retrieving the quality control data through the second strategy specifically comprises the following steps:
s41, verifying the identity of a quality inspector and automatically matching a cold chain path corresponding to the unique equipment code scanned by the quality inspector after the identity of the quality inspector passes the verification (the identity verification method of the quality inspector is a conventional face recognition verification method, and the identity of the quality inspector is verified firstly when the quality inspector scans the unique equipment code); the cold chain path refers to a path through which different cold chain products pass through different cold chain links. For example, assume that there are 4 cold chain links, which are: freezing processing, frozen storage, refrigerated transport and delivery, cold-stored sale, there are two refrigeration plant in this cold chain link of freezing processing, be refrigeration plant 1, refrigeration plant 2 respectively, this cold chain link of frozen storage has one and stores equipment 1, this cold chain link of refrigerated transport and delivery has configured a refrigeration plant 1 in the transport vechicle, and there is a refrigeration plant 2 in this cold chain link of final refrigerated sale, then the cold chain product has two cold chain routes in this 4 cold chain links, first cold chain route is: freezer 1-storage 1-refrigerator 2, the second cold chain path being: freezer 2-storage 1-refrigerator 2. If the quality testing personnel sweep the unique equipment code of the refrigeration equipment 1, the platform automatically matches a first cold chain path and a second cold chain path. In an actual application scenario, a cold chain path is set in advance by a user, namely, when a cold chain task is sent next, the cold chain path is already set, and cold chain equipment in different cold chain links at least has one cold chain path.
S42, obtaining a unique device code corresponding to each cold chain device in each matched cold chain path, then matching binding information corresponding to each obtained unique device code in a specified period from the database, and forming a binding information set corresponding to each cold chain path as quality inspection data required by the current quality inspection behavior, where the specified period is a forming time allowed range of the quality inspection data required for obtaining quality inspection, for example, the specified period is set as: taking the time when the quality testing personnel scans the unique equipment code of the cold chain equipment as the current time, and searching the binding information set corresponding to each cold chain path within 3 days before and after the retrieval; it should be noted that, for example, for a first cold chain path of the freezing device 1-the storage device 1-the refrigerating device 2, if the cold chain action only executes 3 cold chain links of freezing processing, freezing storage, and refrigerated transportation and distribution, when the quality inspector scans the refrigerating device 1 in the cold chain link of freezing storage, because the cold chain action has not yet executed the cold chain link of final refrigerated sales, the binding information set corresponding to the matched cold chain path only includes the binding information corresponding to the freezing device 1, the storage device 1, and the refrigerating device 1, but not the binding information corresponding to the refrigerating device 2.
It should be noted that, usually, corresponding quality inspection personnel are configured for different cold chain links, and the quality inspection personnel in the corresponding cold chain link is usually only interested in compliance of cold chain operations and the like of the current cold chain link or the previous cold chain link in the current and same cold chain path, so that preferably, when acquiring the binding information set corresponding to each cold chain path, the binding information corresponding to each cold chain device scanned by the quality inspection personnel in the specified period of the corresponding position node of the cold chain path where the cold chain device is located and each cold chain device of the previous position node is acquired, and the binding information set corresponding to each cold chain path is formed as the quality inspection data required by the quality inspection behavior.
The method for acquiring the binding information corresponding to each cold chain device in the designated period comprises the following steps:
a1, a platform firstly acquires all binding information corresponding to each cold chain device in each cold chain path serving as a quality inspection data acquisition object from a database;
a2, analyzing second time for forming the binding information recorded in each piece of binding information corresponding to each piece of cold chain equipment;
a3, judging whether the second time corresponding to each piece of binding information is in a specified period,
if so, taking the binding information as quality inspection data required for quality inspection of the cold chain link where the cold chain equipment is located;
if not, filtering the binding information;
a4, further analyzing the unique cold chain subtask codes recorded in each piece of binding information retained after the filtering in the step A3;
and A5, classifying the binding information carrying the unique code of the cold chain subtask under the corresponding cold chain event according to the attribution relationship of the cold chain subtask and the cold chain task and the corresponding relationship of the cold chain task and the cold chain event, and finally forming the binding information respectively corresponding to each cold chain device in each cold chain path under each cold chain event in the specified period as quality inspection data.
For example, the method for classifying the binding information under the corresponding cold chain event is as follows: the cold chain task created in the step S1 includes a plurality of cold chain subtasks respectively corresponding to different cold chain links under the same cold chain event, each cold chain subtask has a unique code, for example, the unique code of the cold chain subtask 1 is bm0001, the unique code of the cold chain subtask 2 is bm0002, the unique code of the cold chain subtask 3 is bm0003, the 3 cold chain subtasks belong to the same cold chain task encoded as bm01, and based on the attribution relationship of bm0001, bm0002, bm0003 and bm01, the cold chain task encoded as bm01 can be quickly matched, and the event number of the cold chain event corresponding to the cold chain task encoded as bm01, for example, is sj01, according to the preset association relationship between bm01 and sj01, the cold chain event corresponding to the cold chain task of bm01 can be quickly matched.
After the quality inspection data required by the quality inspection is retrieved, with reference to fig. 1, the closed-loop cold chain monitoring method provided by the invention is transferred to the following steps:
and S5, the platform judges whether the cold chain event is in compliance or not through a third strategy based on the quality inspection data retrieved in the step S4, and pushes a judgment result to a quality inspector.
The method for judging whether the cold chain event is in compliance through the third strategy specifically comprises the following steps:
s51, analyzing the content of each piece of binding information contained in the quality inspection data generated under each cold chain event;
s52, judging whether the cold chain temperature and/or the cold chain humidity of the cold chain equipment recorded in the analyzed cold chain environment information fall into the allowable temperature range and/or the allowable humidity range corresponding to the cold chain equipment recorded in the analyzed cold chain subtask,
if yes, judging that the cold chain temperature and/or the cold chain humidity of the cold chain link of the cold chain equipment are/is in compliance, and turning to the step S53;
if not, judging that the cold chain event is not compliant, marking the non-compliant cold chain equipment and the cold chain link where the cold chain equipment is located, and pushing a marking result and a non-compliant judgment result of the cold chain event into a quality inspection result to a quality inspector;
s53, identifying the analyzed identity information of the cold chain personnel in the real-time video stream monitored by the monitoring device special for monitoring the cold chain equipment (the identification of the personnel identity can be realized by the existing identity identification algorithms such as face identification and the like);
s54, judging whether the identity of the identified cold chain personnel is consistent with the identity information of the cold chain personnel carried in the analyzed cold chain subtask,
if yes, judging the cold chain operation compliance of the cold chain personnel in the cold chain link, and turning to the step S55;
if not, judging that the cold chain event is not in compliance, marking the cold chain personnel who operate in violation and the cold chain link assigned to the cold chain personnel, and forming a marking result and a non-compliance judgment result of the cold chain event into a quality inspection result and pushing the quality inspection result to quality inspection personnel;
s55, judging whether all cold chain personnel in all cold chain links in the same cold chain event operate the compliance,
if so, judging the compliance of the cold chain event, and pushing a judgment result to a quality inspector;
if not, judging that the cold chain time is not in compliance, and pushing the judgment result to a quality inspector.
In conclusion, each cold chain device in each cold chain link is endowed with a corresponding unique device code, and a special monitoring device is arranged for each cold chain device, so that the special device is automatically activated to continuously monitor the corresponding cold chain device after a cold chain worker receives a cold chain subtask. And subsequently, when the quality inspection is carried out on the cold chain link, the cold chain personnel who receive the cold chain subtask and the personnel identities which are monitored by the special monitoring equipment and actually execute the cold chain subtask are compared, so that the false behaviors of cold chain operation and the like of replacing qualified personnel by unqualified personnel are effectively prevented. And after the cold chain equipment scans the unique equipment code by cold chain personnel, the cold chain information of the cold chain equipment is actively sent to the platform, so that the problem of information entry and counterfeiting of the cold chain personnel is solved.
