In other embodiments of the present invention, when a material enters a preset process, after scanning a unique code, judging whether a unique code missing condition exists in a preamble step, and it should be noted that, when an MES is used in a production process, personnel is also crucial to execute a process, and because a hand-held terminal is used to scan the code at the beginning and the end of each process, the missing code may exist and directly flow into a next process, and the tracing of the material is disadvantageous, therefore, process nodes are established in advance according to the production process, that is, code scanning authentication is required at each process node, and non-scanned code nodes between two nodes are reminded; if the unique code missing condition exists in the preamble step, judging whether the preamble step of the unique code missing is a key procedure, wherein the key procedure is a preset procedure, and prescribing according to the process requirement; if the preamble step of the unique code missing scan is judged to be a key procedure, the corresponding key procedure is required to be executed again; if the preamble step of the unique code missing is judged not to be a key procedure, the background automatically supplements the lost data and prompts.
Specifically, in the step of automatically supplementing the lost data and prompting the background, the operator information is associated with the record of the supplemented lost data, when the record of the supplemented lost data exceeds the preset times, the operator is checked, and it can be understood that the working state of the operator can be known through the supplemented lost data recorded on the MES, whether the working procedure is strictly executed or not, and the processing such as changing the post or adjusting the post can be performed according to the check result.
More specifically, in the step of automatically supplementing the missing data and prompting, the background counts the procedure of supplementing the missing data in the production line, determines the counted times of the procedure, and when the counted times exceed a threshold value, evaluates the procedure to determine the necessity of the procedure, so as to optimize the whole process and remove unnecessary procedures.
It should be noted that in other embodiments of the present invention, the amount of data generated in the MES system is relatively large and belongs to relatively important data, so how to encrypt the data is also important. Specifically, encrypting data generated during production and manufacture through an MES system each time, wherein basic information of solder paste, basic information of a steel mesh and basic information of a scraper are respectively determined, and an encryption code group of a preset data packet is determined according to a sequence formed by the basic information of the solder paste, the basic information of the steel mesh and the basic information of the scraper, wherein the preset data packet can be data generated under a work order; further, the work number in the current operator information is obtained, corresponding code words are determined from the encryption sub-code groups formed by the basic information of the solder paste, the basic information of the steel mesh and the basic information of the scraper according to the work number, and the code groups formed by the code words are used as pre-encryption code groups; furthermore, the pre-encryption code group and the encryption code group are combined to form a target code group, and the preset data packet is stored in a corresponding database according to the target code group.
Specifically, first, the basic information of the solder paste, the basic information of the steel mesh and the target information in the basic information of the scraper are determined respectively, for example, the solder paste type number, the solder paste type, the stirring time (seconds) and the maximum refrigerating frequency in the basic information of the solder paste, the steel mesh type, the steel mesh cleaning period and the upper limit of the steel mesh use frequency in the basic information of the steel mesh, the basic information of the scraper, the scraper type, the scraper cleaning period and the upper limit of the scraper use frequency in the basic information of the scraper are all converted into pinyin letters for representing possible characters in the target information, and it can be understood that the finally formed encryption code group sequentially consists of pinyin letters and digits according to the determining sequence of the target information.
The method comprises the steps of obtaining a work number in current operator information, for example, the work number is 1856, determining corresponding code words from an encryption sub-code group formed by solder paste basic information, steel mesh basic information and scraper basic information according to the work number, wherein it is understood that the solder paste basic information, the steel mesh basic information and the scraper basic information can respectively obtain the encryption sub-code groups, namely 3 encryption sub-code groups, and determining code words of 1 st bit, 8 th bit, 5 th bit and 6 th bit in the 3 encryption sub-code groups according to the work number of 1856, wherein the 1 st bit is represented as the leftmost code word of the encryption sub-code group, if the number of bits is too large and no corresponding code words exist, obtaining the rightmost code words of the encryption sub-code group, and finally taking the code groups formed by the code words as pre-encryption code groups.
Since the length of the encryption code set may be too long, the length of the encryption code set may need to be limited, meanwhile, the duty ratio of the finally formed pinyin letters and digits of the encryption code set is controlled, specifically, the preset length is obtained, the continuous code words of the encryption code set are randomly intercepted according to the preset length, the number of pinyin letters and the number of digits in the intercepted encryption code set are determined, the duty ratio is calculated, and whether the duty ratio is larger than a preset value is judged, it is understood that the number of pinyin letters is generally expected to be larger than the number of digits, when the duty ratio is smaller than the preset value, the number of pinyin letters needing to be supplemented is determined according to the preset value, the intercepted encryption code set is taken as a reference, the pinyin letters needing to be supplemented are alternately searched to the two sides, then digits in the intercepted encryption code set are replaced according to the reference, in the step of alternately searching the pinyin letters to the two sides of the intercepted encryption code set, firstly, the length of the side with the longer code words of the two sides of the intercepted encryption code set is obtained, the pinyin letters on the side with the longer side of the code words is determined, and the pinyin letters on the side with the longer side are searched, and the pinyin letters on the side of the side is searched alternately.
