specifically, when the number of processes is large in a factory and a certain accessory needs to be searched for reporting a flaw detection result, searching can be performed by filtering the casting number or the decomposition date (when the casting number does not know the decomposition date, the decomposition date is empty and is not selected, otherwise, the casting number is not selected);
specifically, a're-detection qualified' list is formed for the parts with cracks or needing to be welded and repaired in the flaw detection inspection result, and after the parts needing to be confirmed by the re-detection are qualified, the flaw detector checks the're-detection qualified' and submits the parts to the database after the parts are confirmed to be correct.
Further, the self-checking module comprises: the system has two functions of qualified decomposition and flaw detection to self-check and alive decomposition and flaw detection to self-check, and after the flaw detection is qualified or qualified by repeated detection, the system automatically counts out an information list of the flaw detection to self-check according to whether the decomposition detection procedure is alive or not;
specifically, a detected fault self-inspection list is divided into two reports to be displayed, the decomposed parts are qualified and the decomposed parts are alive, the parts qualified in the decomposition and inspection are subjected to default qualification, an operator selects qualified swing bolster parts after the self-inspection is finished, the qualified swing bolster parts are submitted to a database, and the page is automatically refreshed after the self-inspection is successfully submitted;
specifically, the accessories with lives for decomposition and inspection are checked and submitted according to inspection items through a self-inspection interface, after the submission is completed, a 'list with lives for decomposition and inspection waiting self-inspection' is returned, and at the moment, the list still displays the information of the accessories with lives for decomposition and inspection which are submitted just now, and refreshing is carried out;
specifically, the accessories which are qualified in decomposition can be submitted in batch after self-inspection is qualified, and the accessories which are alive in decomposition can only be submitted according to a casting number, a manufacturing date and a factory code, but cannot be submitted in batch;
specifically, the self-inspection interface list is not displayed when the scrapped accessories are subjected to flaw detection or scrapped component decomposition or scrapped component life management;
specifically, qualified accessories are decomposed, a self-checking interface is default 'qualified', live accessories are decomposed, and a self-checking interface is default 'qualified for repair'.
