Definitions
- the invention relates to a gas cylinder, in particular a liquid gas cylinder, which has a plastic element which is firmly connected to the gas cylinder.
- Liquid gas cylinders are often used as an energy source in the commercial and private sector. In the commercial sector they serve as a mobile source of energy for craftsmen, for example in welding, in the private sector as an energy source for heating, cooking and especially grilling. As liquefied gas, propane is mostly used. Butane gas bottles have established themselves in the camping sector. In Germany alone millions of refillable LPG cylinders are constantly in use.
- Gas cylinders must be regularly revised for safety reasons. For LPG cylinders such a revision is due ten years after manufacture or the last revision. During the inspection, the gas cylinder is opened, inspected, cleaned and fitted with a new valve. The revision date is noted on the bottle.
- each gas cylinder is provided with an identifier that indicates not only the manufacturer, the date of manufacture and the contents but also the data required for filling - volume and empty weight. These data are noted on the bottle itself and are clearly visible at least when the bottle is delivered. The data allow access to the production data stored at the manufacturer, which can be retrieved in the event of an accident.
- Gas cylinders are often stored outdoors in the commercial and private sectors and are in the period of their use between production and revision or between two revisions of the Weather exposed. Added to this are transport and handling, which have an effect on the exterior of the gas cylinder, result in damage to the coating and subsequently lead to rusting. Such corrosion damages lead in many cases to the fact that such gas cylinders lose their identification. If the identifier is lost, the bottle no longer meets the safety requirements and must be eliminated during the revision before its actual life has expired.
- RFID transponders are often used for identifying and localizing objects.
- the RFID system makes it possible to retrieve identification data stored by means of a scanner on such articles from the not too great distance by means of the transponder and to also locate and / or identify such objects in the vicinity of the scanner. this applies also for a large number of objects (bulk recognition).
- the range of the transponder depends on the frequency; the shorter the wavelength, the greater the range. Currently, ranges of up to 100 m can be realized.
- the range as well as the transmission quality depend, among other things, on the environment of the RFID transponder.
- conventional RFID transponders on or near metallic surfaces are difficult to retrieve. While there are specific systems that allow such retrieval, these are typically cumbersome and bulky, due to the need for shielding and a special antenna configuration.
- RFID transponders directly on the metal surface of a gas cylinder is therefore problematic, especially if this gas cylinder is in a warehouse with numerous other gas cylinders.
- a transponder on the surface of a gas cylinder is exposed to the weather unprotected, which greatly limits its life. For this reason, it is necessary to arrange RFID transponders on gas cylinders so that they are protected from the weather. Preferably, they should not be limited in the range of data transmission by metallic surfaces. This is achieved by being embedded in a plastic element firmly connected to the gas cylinder.
- the solid and permanent connection of the plastic element with the gas cylinder is necessary because the identification data of the gas cylinder are stored in the transponder and the gas cylinder is no longer clearly identifiable in case of loss of the provided with the transponder plastic element. This also applies if the identifier is stored on the gas cylinder itself, since under unfavorable circumstances it may be lost until the next revision. It is therefore essential that the plastic element with the RFID transponder between manufacture and revision of the gas cylinder or between two revisions can not necessarily and unintentionally be removed from the gas cylinder.
- manufacturer and / or production number, date of manufacture, date of the next revision and empty weight can be considered as identifier or identification data.
- Other data for storage include location, content (volume), delivery data, date of individual fillings, sales data.
- the RFID transponder is preferably embedded in the plastic element and enclosed on all sides by plastic.
- the transponder is injected in the plastic or cast.
- the transponder may be disposed in a slot or recess formed in the plastic element, which is then sealed watertight with a suitable material.
- the plastic element is a valve protection basket made of plastic.
- a valve protection cage is described for example in DE 10 2015 004 951 A1.
- Such a valve protection cage has, for example, a collar for fixing to the neck of the gas cylinder below the valve, a partially circumferential collar with at least one handle opening and an access area to the valve.
- the RFID transponder can be arranged in such a valve protection cage, for example in the collar or in the access area to the valve opposite wall.
- the attachment of the transponder on the dome of the gas cylinder as an in-mold label, so welded in a glued plastic label, which clarifies the handling, safety information, content and capacity of the bottle.
- the transponder sealed in a plastic film, glued to the bottle and pasted over with the usual bottle labels.
- the bottle stickers usually give safety instructions and information about content, capacity and the like.
- the arrangement of the transponder on or in the valve protection cage, in particular in the collar, handle or wall area, has the advantage that in this way a distance to the metal body and valve is produced. This improves the range and quality of the transmitted signals.
- the valve guard thus has the function of a spacer.
- valve baskets are usually produced by injection molding, which allows to insert the RFID transponder in the mold and encase with the plastic. In this case, the transponder is injected.
- the injection-molded body can be provided with a slot or a recess into which or the transponder is introduced and subsequently sealed with a suitable material.
- the valve arranged plastic elements for example in the form of a valve protection basket or a plastic ring, have the advantage that they can not be removed by the customer without rendering the bottle inoperative. This ensures the connection of the identifier with the gas cylinder.
- the Disassembly of the valve also the dismantling of the valve protection cage or collar required.
- the authorized auditors ensure the identity of the gas cylinder over the revision period until the new delivery.
- the "marriage" of the gas cylinder with the identifier takes place during assembly of the plastic element, in particular the valve protection cage.
- the transponder is described with the relevant data, which uniquely identifies the gas cylinder and makes the production data and parameters available via the identifier.
- the gas cylinder receives an identification number during production, which is transmitted to the transponder during assembly of the plastic element and the subsequent labeling of the RFID transponder.
- the valve protection cage can have a cover plate in the region of the fixing collar, which also consists of plastic.
- a cover plate is described for example in DE 10 2015 00 451 A1. Accordingly, the RFID transponder can be arranged in such a cover plate.
- the RFID transponder can also be integrated in any other plastic element which is fixedly arranged on such a gas cylinder.
- This may, for example, be a special collar in the valve region or a plastic band, such as a protective ring in the seam or foot region of the gas cylinder act. It is essential that this plastic element is so firmly connected to the gas cylinder that it can not easily solve.
- the gas cylinder identification should remain inseparably connected to the gas cylinder.
- the RFID transponder should be arranged so that it can not be damaged by external influences. This is especially true when the transponder is located in the neck region of the gas cylinder. If it is placed in a protective ring in the wall area, it can be damaged by "tapping" on a wall or an object. This applies in principle to any exposed arrangement of the transponder, even if it is integrated in a plastic element.
- the RFID transponder is preferably a passive or semi-passive transponder which draws its energy from the scanner signal. If the scanner signal is emitted at high frequency, in particular in the UHF or SHF range, this results in a sufficient range of up to several meters. Also, the bulk capture and capture of individual gas cylinders in a large camp is possible. It is also possible to automate the refilling of gas cylinders by means of a permanently installed scanner system.
- a gas cylinder is understood to mean not only LPG bottles, such as propane, butane or dimethyl ether bottles, but in principle all forms of gas cylinders and containers which contain gases stored under pressure and which are subject to regular monitoring and revision So also common industrial gas bottles.
- the RFID transponder In order to keep the memory requirements for the RFID transponder low, it makes sense to limit the data stored there, for example to the manufacturer, the production number, the date of manufacture, if appropriate the last revision date, and the empty weight. Further data, in particular those which are relevant to safety, can be stored and called up in a central database of the manufacturer or of several manufacturers, if appropriate also of the surveillance institutions. Such data include, for example, manufacturing data, manufacturing parameters, manufacturing materials, test data, delivery date, and revision data.
- the gas cylinder according to the invention offers all parties involved a number of advantages. Thus, at the energy supplier / bottler, the goods receipt can be automatically detected and the bottle can be assigned to a specific storage location and / or a specific filling station. The bottle inventory can be recorded according to categories (unfilled, filled, for revision). A follow-up of the filling cycles of the individual bottles is possible. If necessary, a complete documentation from the production to the end user including the filling cycles and the revisions can be created.
- Gas cylinders are subject to legal and regulatory requirements and proof requirements. These requirements and proof requirements can be met with the help of the documentation.
- the registration of data with the manufacturer and, if necessary, in a central register allows the notified bodies and authorities access to the data and a review with little effort.
- the registration of the bottle data on the RFID transponder disposed in the plastic element provides an effective theft protection.
- the principle of the embedded in a plastic element or sealed RFID transponder with stored product identifiers and data is readily transferable to other objects. This allows, for example, the retrieval of stolen items, such as bicycles.
- the invention also relates to the use of such embedded in a plastic element RFID transponder with stored therein identification data for the identification and monitoring of gas cylinders, in particular LPG cylinders.
- the use also extends to a monitoring system not only for gas cylinders containing such an RFID tag embedded in a plastic element associated with a central database having data stored therein.
- FIG. 1 shows a gas bottle 1 equipped with a valve protection basket with the bottle body 2, a foot 3 and the valve 5.
- the gas bottle is welded together from two half shells, the number 4 designates the weld seam.
- a valve protection cage 6 is fixed with a holder 9 on the bottle neck, which has a partially encircling collar 10.
- handle openings 8 are arranged.
- the collar 10 leaves an access to the valve 5 free.
- the numeral 11 denotes a cover plate for the holding elements of the holder 9. It is essential that the transponder 7 for protection on all sides surrounded by plastic.
