Description

Steel product quality certificate checking system and method based on RFID

Technical field

The invention belongs to the computer information network system technical field, can be used for enterprises such as construction work, shipyard, equipment manufacturing to the steel product quality certificate check in real time at the scene, consult, third party's supervision and the inspection-free authentication of quality.

Technical background

Along with China's economic construction is flourish, steel product is extensive use of in construction work, household electrical appliances, boats and ships, automobile, railway and equipment manufacture.Steel product quality certificate (be called again " material single ") is the producer or wholesale dealer to the quality condition of the steel product that the is dealt into the user appended documentation of making an explanation, and just as same " I.D. ", has wherein comprised the name of product of steel, the place of production, date, heat (batch) number, kind, model, size, weight, operative norm, information such as chemical constitution, and physical property such as yield strength, pulling strengrth.It can prove steel quality and performance characteristic, and the foundation that is to use unit product design, manufacturing process to select also is the main legal basis in engineering or the product quality objection issue handling.

Steel mill generally provides the product quality certificate of written print form, and certificate should be sent in applying unit and the user's hand with product.But because the delay of steel mill on management links such as quality certificate printout, distribution audit, and many intermediate links such as steel sale enterprise, logistics transport enterprise lack necessary file management means and ability, applying unit often can't in time acquire the certificate of quality file of this batch products in steel product examination and use.Press national regulation, steel product lacks quality certificate, or certificate batch and actual product batch are not inconsistent, applying unit must not be checked and accepted, product must be sealed the process that just can put into production behind producer or the dealer's polishing certificate of quality file up for safekeeping, has so just had a strong impact on the project progress and the production schedule.

Be a minimum batch production unit with a retort steel when steel mill produces steel, the attached a product quality certificate of one batch product.Batch of several at least of a steel product (bundle/volume), tens (bundle/volume) at most, in storage, shipment and logistics distribution process, the product that same kind, different batches often take place loads in mixture phenomenon, at this moment, the batch number of quality certificate and every (bundle/volume) product often can't be corresponding one by one, wastes time and energy very much when product is delivered for a check, and be easy to generate the product quality objection.

On the other hand, domestic steel production enterprise is numerous, and is very different, and the steel mill of some no production licences utilizes the careless omission part in the above-mentioned management process, palms off regular producer steel product quality certificate, the defective steel product of mass selling.These steel products of poor quality flood market, had a strong impact on development of economic construction, disturbed the enforcement of national energy-saving and emission-reduction and industry restructuring policy, even cause casualties and property loss, therefore, the quality certificate that is necessary to strengthen energetically and improves steel product market circulation, deliver for a check with production run in supervisory system, for applying unit and regulator provide the method and system of real-time examination to every (bundle/volume) steel product quality certificate/consult, for product is delivered for a check and production facilitates.

In recent years, the fast development of Computer information network technology, especially the widely application of low cost RFID electronic label technology, for products such as grain, agricultural product, concrete in production, storage, transportation and process quality control and trace to the source new technological means be provided.For example patent " a kind of system of reviewing by RFID realization product quality " (patent No. 200720109629.5) is carrier with the release, the mode of sequence delivery product certification ID sign indicating number between each link provides a kind of quality tracing system that is applied to agricultural product production, processing and intermediate links; Patent " based on the control system and the control method of the supply chain quality management of RFID " (patent No. 200810197397.2) provides the method that realizes quality information collection and control in a kind of manufacture course of products according to the RFID label.Above System and method for can't can't be worked under the sequence delivery situation in intermediate link disappearance, information.But because the singularity of steel product, the checking of saving intermediate link helps to reduce the checking cost.Up to now, do not see as yet directly RFID and information technology application in the report of steel product quality certificate examination in real time with the system and method for consulting, the distributed examination and the third party that also do not have a kind of System and method for can finish on a plurality of servers authenticate.

In addition, many domestic iron and steel enterprises have been set up fairly perfect quality information management system, have possessed automatic generation and the data base administration and the inquiry system of collection to quality informations such as the Material Physics of steel product after the manufacturing processes such as collection, calendering or annealing in process of every stove (jar) steel blank main chemical elements content result of laboratory test in the production run and mechanical test results, recording storage, quality certificate literary composition retaining.The computer information system of some steel mills only supplies inner management personnel artificial enquiry, and product quality information can't be delivered in final user's hand with convenient, real-time method.

Summary of the invention

Existing system can not be delivered for a check at product to the steel product applying unit in order to overcome, check, consult the testimonial deficiency of product quality in real time in the manufacturing process, the invention provides a kind of new checking system and method, by the distributed system framework that a plurality of different user end RFID examination equipment and a plurality of different steel mills servers are formed, make the user make things convenient for examination at the scene, consult the quality certificate of steel product.System is further perfect, also can expand third party's supervision and policy of benevolence function.
