Definitions
- the invention relates to a device for detecting changes in the measured value at a place of use, comprising at least one electrically conductive element.
- Evaluation unit for example in the form of an A-RFID (active
- Radio frequency identification transmitter sends this resistance change to a receiver, thus triggering a kind of alarm. This is especially relevant before delivery of a vehicle. Since all cables are routed manually and glued, this requires a long working time (the so-called F-time), which leads to high costs.
- Another method is the so-called stinging, in which metal bars are stung by the covering of the footwell of a car, in particular by a carpet of a car, to then measure the ohmic resistance and make a corresponding evaluation. This system-related damage to the carpet of the vehicle, which is of course not desirable.
- Object of the present invention is therefore to provide a device for
- a device for detecting changes in measured values at a place of use comprising at least one electrically conductive element - for example, and in particular a conductor track - wherein the electrically conductive element with respect to the measured value changes - for example, and in particular the ohmic
- the electrical conductivity - the electrically conductive element is configured at the site of use configured; This means that at the place of use - for example, and in particular on a car body - the electrically conductive element is both manufactured - that is applied at the place of use - as well as configured - ie at the site in terms of its spatial or planar extent - is. Unlike laying a conventional cable, yes already
- the device according to the invention differs from conventional printed circuit boards printed circuit boards in that they are not part of the site, but can be provided only at the site.
- Device according to the invention is determined by the spatial extent of the site itself. This represents a significant difference from the embodiments known from the prior art. In this way it is possible to take into account both difficult configuration conditions of the place of use and on the other hand pronounced this
- the configuration is realized by means of application on site, for example, and in particular if the application is realized by means of spraying, brushing, painting, painting, gluing or brushing, as these applications have proven to be fast and secure feasible.
- the measured value changes are changes in the electrical conductivity, since these are
- the producing configuration is the production of electrically conductive regions.
- the electrically conductive areas are strip-shaped areas.
- the electrically conductive element has a specific resistance of 0.1 ohm.cm to 10 megaohm.cm and / or if, in the configuration produced on site, the electrical resistance of the electrical element in the
- Range is from 0.1 ohms to 10 megohms.
- the electrically conductive element is a lacquer.
- At least one electrically conductive material may be added, in particular if the added material is graphite, metal, in particular aluminum or copper.
- the device according to the invention comprises at least one element from the group: RFID tag, CAN-BUS chip, A-RFID, passive RFID, cable, USB adapter, measuring point, trace, Battery, power source.
- inventive device is used.
- the moisture sensor as anti-theft, as a level indicator, leakage protection, as an alarm sensor, as a moisture alarm and for moisture measurement, in particular, if an application takes place in motor vehicle, truck, two-wheeled, aircraft, rail vehicle, ship, building, Clothing, containers, hose, fence, housing, wood, battery.
- Figure 1 - a perspective view of an embodiment of
- Figure 1 is a sketch and perspective a section of a
- Conductor pair consisting of a conductive paint, directly on the
- Vehicle floor has been sprayed.
- the individual interconnects are electrically connected to one another at one end, namely with a further interconnect of the conductive lacquer; in other words: it is applied during the spraying of a conductor track of the electrically conductive paint on the vehicle floor, wherein the course is designed such that two conductor tracks Run opposite each other and are electrically connected at a leksachsialen end with a quasi-perpendicular to the course of the two opposing interconnects extending short trace piece.
- the ohmic resistance between the two tracks is in the short track piece not injured state about 10 megohms. If there is an injury, the electrical resistance increases to about 50 megohms.
- the ohmic resistance drops to about 100 kiloohms, so that this value determined by an electronic evaluation unit is transmitted to a receiver by means of an active RFID to immediately detect whether moisture is present on the vehicle floor or not.
- the active RFID is powered electrically by means of a battery, not shown.
- the electrically conductive lacquer is the weather-stable synthetic resin clearcoat Yachtline SKE 0000, colorless, from Wilckens GmbH, Germany, which consists of an alkyd resin with inorganic fillers and de-aromatized white spirit.
- This synthetic resin paint about 5 g of nanoparticles of graphite are added to 100 g to ensure the necessary electrical conductivity.
- this paint is sprayed directly onto the inner top of the vehicle floor.
- a corresponding device according to the invention can be created and installed at the place of use, the spatial specificities of the vehicle floor - and thus also its configuration - the corresponding spatial
