Typical application of the industrial internet of things-quality tracing: when a product has a quality problem, all products with similar quality problems can be found based on the product data with the found problems. However, the product with quality problem located by quality tracing needs to be finally judged by human, but in the face of thousands of products, the factory logistics cannot pause normal processing due to part of the suspicious products, and the judgment and treatment of the suspicious products are hindered.
The traditional quality analysis system can preliminarily position the range of the suspicious product, but cannot solve the following problems from the aspect of suspicious product control:
1) in a factory, factors such as persons, machines, materials, methods, loops and the like are traced from the appearance of suspicious products to the tracing location, related similar products cannot be fed back to an operator in real time, and related operations of the operator often cause the range diffusion of the suspicious products.
2) For a continuous production plant, the production stop time is avoided, and related personnel can detect, locate and control all suspicious products. And the normal production is influenced in the implementation process.
3) For a production line with more working procedures, the related lists of suspicious products for analysis and positioning are often large in quantity, and if the lists are manually controlled and processed uniformly, the cost on time and labor is immeasurable.
4) Traditional quality control, from upper management personnel to operators, can not guarantee accuracy and no leakage.

(6) the materials with the containment marks are put into a containment warehouse for unified processing;
(7) and (4) judging the restrained articles by related personnel, redefining and separating the quality of the suspicious articles, and releasing the restraint after the whole material is judged.
Preferably, the key information is expressed as material + batch number, equipment + time, equipment + model number + time and raw material bar code.
Preferably, when the reason of the suspicious product is located, the problem reason of the suspicious product can be accurately located by utilizing big data analysis on the collected data of people, machines, materials, methods and tests based on an analysis system.
Preferably, the suspicious list of the current latest data is obtained as follows: the tracing analysis system determines the range of the suspicious products based on a past time period, and calculates the current time, so that the suspicious product range is circulated to generate a new suspicious product list.

Detailed Description
The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto:
example (b): as shown in fig. 1, the traceability analysis system analyzes based on a large amount of factory data acquired by the MES system and the logistics system, locates the reason of the suspicious product and converts the reason into the dimensional factor generated by the suspicious product, obtains a real-time list of the suspicious product by tracking the analysis system and the logistics system, marks the suspicious product in the list, and limits the actions of delivering, producing, returning, forwarding, ex-warehouse, delivering and the like of the problem product by judging the mark.
The containment branch tracks and contains two parts:
a tracking part: the tracing analysis system analyzes the big data to obtain the reason of the suspicious goods and converts the reason into the dimension factor of the suspicious goods, primary tracking is carried out according to certain dimension conditions, the analysis result and the containment instruction are sent to the logistics system, the logistics system carries out secondary non-repeated calculation based on the obtained result to obtain a real-time list of the suspicious goods, and containment marking is carried out on the suspicious goods in the list.
The containment part is that the logistics system limits the circulation of the materials marked with containment marks before various operations of the workshop and the warehouse; for materials which have containment marks and are being processed by equipment, the new materials generated increase the containment marks.
As shown in fig. 2, a containment method based on a logistics system and a retrospective analysis system mainly includes the following steps:
(1) the part factory finds that the parts have problems, and the detection personnel firstly determine the problems through quality inspection. Determine sources of problems such as: working procedures, materials and the like.
(2) Through the traceability of the analysis system, the whole logistics state is checked, and the wrong logistics node is positioned, and the node can be often interpreted as key information such as 'material + batch', 'equipment + time', 'equipment + model number + time', 'raw material bar code' and the like by the analysis system.
(3) The analysis system executes containment by operating the page, and the analyst enters the relevant description of containment.
(4) And (4) tracking a suspicious item list based on the current latest data by the analysis system based on the key information in the step (3). The process is huge in data quantity, and the advantages of large data analysis and calculation are fully exerted.
(5) Because the continuous flow of the factory logistics and the time difference from the analysis system to the logistics system cause the data lag, the logistics system performs secondary non-repeated calculation based on the calculation result of the analysis system to obtain the real-time logistics state of the suspicious product based on the bar code and the logistics snapshot.
(6) The marking of the suspicious material is divided into two parts: a part is generated by the step (5); another part is generated by plant logistics actions such as production, material return, plant adjustments, etc. (not all circulation actions are allowed for the contained material). For the new bar code generated by the latter, the logistics system will add a containment flag. By the marking mode, the logistics system can control the real-time situation of the materials, the restrained materials and the unrestrained materials can be processed in a distinguishing mode, and the influence on factory production is reduced.
(7) For the circulation of the material, whether the material is marked in a restrained mode or not is checked based on the bar code, when the material is marked, the operation of a part is limited, and a user is prompted, for example: feeding, warehousing, delivery and the like. All the control is automatically completed by the logistics system, and other operations except daily work of operators are not needed for auxiliary support, so that the personnel cost and the communication cost are reduced. Description of the drawings: a plurality of restraining actions of a factory can exist simultaneously and are not interfered with each other, if a certain material is restrained by a plurality of restraining actions simultaneously, the restraining actions are cancelled, and then the material flow is allowed to continue.
(8) After the containment marking, the actual processing mode of the suspicious goods in the factory is different according to different factory management;
and (4) judging the contained article by related personnel, and redefining and separating the quality of the suspicious article.
(9) When all the suspicious materials are checked and judged, the restraining action can be released.
In conclusion, the invention can directly control the circulation of the same kind of products being processed through the analysis system only by analyzing the problem products, and has quick response; the material circulation is controlled based on a controllable range, and the influence surface is small; the factory action coverage is comprehensive, and the mark from analysis to logistics control is real-time and complete by adopting a tracking algorithm; almost one-button control of the circulation of suspicious products is realized, and the management cost is low.
While the invention has been described in connection with specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
