Description

INSTALLATION FOR THE MAINTENANCE OF DATA OF THE PRODUCT FIELD OF THE INVENTION The invention refers to an installation for the maintenance of product data during a life cycle of the respective product. DESCRIPTION OF THE PREVIOUS TECHNIQUE When a product requires a documentation that accompanies it during its life, respective relevant data must be stored for example in the system of pre-manufacturing, manufacturing, assembly of preparation of the material and quality as well as during the use of the product and service until the recycling process included. Until now it is usual to record the life cycle data of the product in attached papers and test protocols in the installation sites and to archive them in a decentralized or centralized way. A filing method for this purpose is for example microfilming. However, access to all this data is only possible, if it exists, with considerable expense. SUMMARY OF THE INVENTION The purpose of the invention is to keep production and product data available in accordance with the quality system in an electronic product pass during manufacturing, assembly, service and during recycling. The compatibility with quality systems such as ISO9000 must be guaranteed. According to the invention, this task is solved in an installation of the type mentioned at the beginning because a data medium that is writable and electronically readable permanently, but not simply erasable as a chip card, is assigned to the product both with basic data of the product as well as with clear text identification corresponding to them optically readable and because with events of the life cycle of the product, such as manufacture, final test, review, shipping, operation in the user, service and maintenance, disassembly and recycling can be completed basic data of the product, by means of electronic devices of writing-reading, with additional data conditioned by these events. In this way, the quality and equipment of the product can be documented in an extremely simple way during the life cycle of the product and can always be followed. The invention provides the user with special advantages: scarce documentation of paper or paperless and control of manufacturing, assurance of the ability to monitor the quality of the product in the framework of manufacturing, assembly, service and recycling processes, documentation of the test results, review and maintenance work in the different phases of the life of the product, assurance of the service capacity and maintenance of the product through the documentation of damaged parts (parts variants, equipment, etc.) or designations of batches used, documentation of test results, defective parts for checking review work, checking in the case of product liability cases - facuitamiento maintenance work through specific product documentation of the variants of parts used, facilitation of the recycling process through the documentation of the pieces s or existing spare substances. A first advantageous configuration of the invention is characterized in that by means of a coding the read-write devices assigned to the sections of the life cycle have access in each case only to the basic data of the product and to specifically predeterminable minimum quantities of the additional data . In this way, security is guaranteed against unauthorized access to the database. Another configuration of the invention is characterized in that in each case at a predeterminable point of the product life cycle data of the data carrier can be filed in large volume memories and because for the next life cycle the original data carrier can be replaced by a new data medium of the same type, in which only a minimum amount of the basic data of the product and of the additional data so far meaningful for the next life cycle of the product can still be written. In this way it can be ensured that irrelevant data for the user of a product is not already stored in the chip card that is delivered to him. In this way, unnecessary storage of memory space can be avoided, on the one hand, and sensitive manufacturing data, which are not important to the user of the product, are completely suppressed. An exemplary embodiment of the invention is shown in the drawing and is explained in detail below. In this case: BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows the front view of a chip card. Figure 2 shows its rear view, and Figure 3 shows an image of the structure. DETAILED DESCRIPTION OF THE INVENTION In the representation according to figure 1, the front view of a data carrier, in this case a chip-C card, is shown with a large memory volume. In this case it can be a volume in the magnitude between 6 and 64 MB. By means of contact surfaces, which are indicated in the representation by means of oval fields, a C-chip card of this type can be permanently written and read electronically in reading-writing devices, which are still being discussed. continuation. The reading and writing processes are evidently carried out by means of encrypted encodings. Obviously, in principle contact surfaces could also be used as in commercial telephone cards. In addition, information on basic product data can be made in clear text on the chip card C. In the representation according to figure 1 this information appears: Service card for product xyz ID for product Manufacturing data Equipment Service data Anti-theft protection Key function Material pass for recycling For xyz, then, for example, a vehicle type can be indicated, for which a vehicle frame number can be used in this case for the product ID. In addition, additional graphic elements, for example signature marks and the like can be printed on the chip card C. In the illustration according to FIG. 2, the rear side of the chip card C described above is shown. Here an impression can be provided. In the embodiment, the printing is divided as follows: ID service card for product Quality pass Signature Manufacturing workshop abe Date 01.05.95 For abe you can indicate in clear text the manufacturing workshop, for example the respective automobile factory. In the representation according to figure 3, the cooperation of writing devices SL1 to SL8 with chip cards is represented. In the first place, the chip card with specific printing of the workshop is provided in a block I, in addition basic data of the product, especially the order data, are registered by means of a writing or reading installation, not represented for clarity, of the chip card. Next, the chip card is inserted in a bag attached to the car and arrives with the product in the first place for manufacturing / assembly. There the current data content is completed by means of a read-write device SLl with specific data of the manufacture or assembly. These data are: information about customers, product, equipment, delivery date, manufacturing sequence, start-up date, ID, registration. From production / assembly, the product arrives at the final test, where the additional data of the chip card obtained in the final test are additionally electronically entered with the help of an SL2 read-write device. In this case it can be: quality control data, test results, used or defective or modified parts or previous products, real terms, manufacturing sequence. In the flow diagram, from which both the arrangement of the installation and the cycle of the corresponding procedure can be deduced, it is now shown that the product has eventually required a review. For this purpose, in a two-stage work mode, a complement with the following data can be produced on a SL3 read-write device: quality control data, test result, theoretical review sequence, review processes, the dedicatory case of the product. In a read-write device SL4, which is also assigned to the review stage, the following additional data may be completed: quality control data, test result, actual work sequence, review documentation. The product is now completely finished and ready for delivery. By means of the trace path it is indicated that the product now arrives with a chip card corresponding to the shipment and there additionally receives in an SL5 read-write device the following information: delivery mode, dates of the agent, service data, date Real delivery, recycling data. In the next life section User operation, data relevant to the service can be entered by means of a read-write device SL6. In the Service and Maintenance life section, the following data of the chip card can be printed by means of a read-write device SL7: service data, test results, modified parts in the service, theoretical / actual service dates . For the modern monitoring of the product it is also essential the consideration of the Dismantling / recycling life section. There can be given through an SL8 write-read device of the chip card the additional information about: recycling data, disassembly sequence, use of parts. When the product has now reached its end of life, the data of the chip card can be documented in a block IV with the help of other writing-reading devices not indicated for clarity, for example on CD-ROM and then You can create a file of this data. The respective write-read devices SL1 to SL8 can receive encrypted codes in each case, so that only a partial section of the information stored on the chip card can be written or read. It has been shown that during the generation of the product many data are obtained, which are irrelevant for the subsequent life of the product and should only be documented in the manufacturer. For this case, it is provided that the original chip card is separated into a block II of the product itself, that a file of the information of the original chip card is produced in the manufacturer, for example on CD-ROM and in a block III is created a new chip card corresponding to the first chip card, which nevertheless contains only the additional data relevant for the subsequent life of the product. This other chip card then accompanies the product until the end of its life. The chip card can be used, for the rest, also for identification purposes similar to a car key or a vehicle certificate.
