Definitions

  • the invention relates to an alarm device comprising a fabric comprising a carrier fabric and integrated therein electrical alarm conductor textile fabric and a damage detector for monitoring damage to the fabric.
  • the invention further relates to a manufacturing method for such an alarm device and a method for its operation.
  • the EP 2 180 453 A1 discloses a device having a web-like knit and electrically conductive wires integrated therein.
  • a first wire is arranged in the longitudinal direction of the web-like knitted fabric and a second wire runs in a meandering manner over the width of the web-like knitted fabric in its longitudinal direction.
  • the two wires are connected in series and connected at the end to a measuring electronics, which measures the electrical conductivity of the series connection.
  • a measuring electronics which measures the electrical conductivity of the series connection.
  • the entire arrangement is no longer functional.
  • Another disadvantage is that the meandering Introducing the wires in the knit requires a complicated handling and that the knit is dimensionally stable only limited.
  • the present invention seeks to further improve the known in the art products and methods and to provide a reliable, easy to produce and large-scale usable design for an alarm textile for planar monitoring of objects.
  • the invention is based on the idea of integrating a modular alarm grid in a carrier fabric in a simple manner. Accordingly, the invention proposes that the alarm conductors are woven as warp threads and / or weft threads forming at least one flat alarm cell in the carrier fabric, and that the alarm conductors are each connected via a separate current path separately from each other with the damage detector. Thus, each alarm conductor can be separated from the other alarm conductors via its own circuit integrity, ie current flow be monitored. A burglary that is possible only with penetration of the fabric can thus be localized due to the interruption of one or more alarm conductor. Such a local damage point can later be ignored as defective without the entire structure becoming inoperable.
  • the textile fabric can be adapted to different contours of an object and incorporated into a suitable receiving structure, for example an outer shell of the object.
  • the damage detector is connected via a group of mutually parallel supply lines, each with an alarm conductor, so that a simplified contacting and targeted control is possible. It is advantageous if the leads are woven into the carrier fabric and are electrically connected at crossing points, each with an alarm conductor. To connect with an electronic To optimize circuit carrier, the mutual distance of the leads in each group should be smaller than the thread pitch of the carrier fabric.
  • a further improvement can be achieved in that the mutual distance of the parallel alarm line is a multiple of the thread spacing of the carrier fabric. In this way, a high structural stability can be created with sufficient spatial resolution with reduced manufacturing costs.
  • the carrier fabric can additionally assume an amplification function.
  • a further advantageous embodiment provides that the alarm conductors running parallel to one another are connected to the damage detector via a common collector return line, in order thus to obtain closed circuits in a simple manner.
  • a plurality of alarm cells are arranged modularly next to one another in the carrier fabric, so that different sized alarm areas can be implemented flexibly in a uniform production.
  • the damage detectors of the alarm cells are coupled via bus lines to a higher-level control device are, with the bus lines are woven into the carrier fabric.
  • a fabric structure which is particularly preferred for the purpose of use provides that the textile fabric including the alarm conductor is formed in a half-turn weave, wherein the straight stretched warp threads and weft threads lie one above the other in one thread plane and are wrapped around binding threads on their outer sides facing away from one another.
  • an electronic circuit carrier in particular a circuit board of the damage detector is firmly applied to the textile fabric.
  • the alarm conductors are woven in a uniform weaving process together with the carrier threads of the carrier fabric to form the textile fabric.
  • the carrier threads of the carrier fabric to form the textile fabric.
  • the alarm manager initially as a continuous Warp threads and / or weft threads are woven and then severed between the alarm cells.
  • the alarm conductors are electrically contacted only after being woven into the textile fabric in the region of their end sections with woven-in connecting lines. For a targeted contacting a layer structure of the tissue is advantageous.
  • a further aspect of the invention is realized in the operation of an alarm device according to the invention in that by a separate energization or separate control of the individual current paths damage in the grid-shaped alarm cell is selectively located and optionally displayed by triggering an alarm signal. It is also possible that a recognized as damaged area of an alarm cell is hidden in a subsequent signal detection or ignored as defective, so that the entire device remains usable without complete loss of function. This is particularly advantageous in a covert fixed installation in a structure in which no other repair option is practicable.
  • the alarm device 10 shown in the drawing comprises a flexible textile fabric 12 and a damage detector 14 for monitoring a local damage of the fabric 12.
  • a damage detector 14 for monitoring a local damage of the fabric 12.
  • the fabric 12 comprises a carrier fabric 16 and therein as a conductive Threads woven electrical alarm conductors 18, 18 ⁇ on.
  • the alarm conductors are arranged as alarm warp threads 18 and alarm weft threads 18 'of the textile fabric 12 in a grid.
  • the carrier fabric 16 consists of perpendicular crossed warp warp yarns 20 and carrier weft yarns 20 '. All warp threads 18, 20 are arranged in a common upper plane or warp thread layer, while the weft threads 18, 20 'are located in a common lower plane or weft thread layer.
  • the fabric cohesion is achieved in the manner of a leno weave by binding threads, which in Fig. 1 the sake of clarity are not shown.
  • the damage detector 14 is electrically conductively connected to a respective alarm conductor 18 ', 18 via a group of mutually parallel supply lines 22, 22', as shown in FIG Fig. 1 symbolized by connection points 24.
  • the alarm conductors running parallel to each other as warp threads 18 or weft threads 18 are connected in groups to the damage detector 14 in groups via a common collecting return line 26, 26 '.
  • the mutual distance the alarm conductor running parallel to one another ie the alarm warp threads 18 or alarm weft threads 18 ', is many times greater than the thread spacing of the carrier warp threads 20 and carrier weft threads 20'.
  • the alarm conductor spacing may be about 25 cm while the in Fig. 1 not shown to scale closer thread spacing of the carrier fabric 16 may be in the range of 1 cm.
  • the thread pitches can be adjusted depending on the requirements and also be chosen differently in the warp and weft directions. It is also possible to select an increased thread density of the carrier material in the area of the alarm conductor.
  • the carrier fabric 16 should be open-meshed and yet dimensionally stable, whereas high demands are placed on the accuracy of the thread layers in the grid of the alarm conductor 18, 18 'due to the required contacting.
  • the supply lines 22, 22 ' may have a higher thread density than the carrier fabric 16, so that an electronic circuit carrier 28 of the damage detector 14 applied in the crossing region can be limited to a small area of, for example, 2 ⁇ 2 cm.
  • each alarm conductor is independent of its own circuit or current path and can be checked separately from the other alarm conductors for continuity.
  • the alarm warp thread 18 2 can be checked for unimpeded flow of current via the specific feed line 22 contacted at the connection point 24 and the collecting return line 26 by means of the damage detector 14. If the alarm warp 18 2 severed, the current passage is interrupted and located according to a burglary. With this structure, the spatial resolution can be adjusted by increasing or decreasing the dimensions of the alarm cell 30 accordingly.
  • two alarm cells 30 can be arranged next to one another in the direction of the carrier weft threads 20' be, while in the direction of the carrier warp threads 20, so in tissue production direction, a plurality of alarm cells 30 can be behind each other. It is possible to couple the damage detectors 14 of the alarm cells 30 via bus lines 32 with a higher-level control device 34, wherein the bus lines 32 are woven into the carrier fabric 16. In principle, it is possible to register a severed alarm conductor or circuit in the control device as damaged and no longer to be taken into account for a subsequent alarm detection, so that the device does not have to be completely replaced and yet is largely functional.
  • the warp thread layer formed from linearly stretched alarm warp threads 18 and carrier warp threads 20 lies on one side on the correspondingly formed weft thread layer, so that one side of the fabric is formed by the position of the warp threads and the other side by the position of the weft threads.
  • a non-slip binding is achieved by binding threads 38 that traverse both thread planes and wrap around the main threads on the outside.
  • the carrier fabric consists of synthetic filament yarns, preferably of PES multifilament yarns.
  • the alarm conductors introduced therein may be silver-coated, insulating sheathed polyamide threads or enamel-insulated copper wires. The insulation prevents unwanted contact at the intersections. In this case, only one of the two thread systems (warp or weft threads) can have an insulation.
