Description

The utility model relates to fencing devices, namely to break-type signaling networks used in barrier devices in order to determine the location of breaks, holes and detect the penetration of unwanted elements into the protected object. The technical solution can be used, in particular, for signaling about unauthorized entry into the protected object, for example, for protecting value storages, as well as for protecting safes, suitcases and similar storages. The expanding volume of production of safes and the construction of structures in which there are premises designed for storing objects attractive for theft requires an expansion of the arsenal and improvement of technical means designed to protect them.

A flexible fence for use in an alarm system is known in which a sensitive conductive element is interwoven with a fibrous matrix material to create a mesh over at least a portion of the fence. The weaving is preferably accomplished by knitting the conductive wire together with the thread that forms the matrix of the fence. The fence can further include a protective outer layer on one or both surfaces of the fence (US 005677674).

The disadvantage of this technical solution is the difficulty of using a wire of small diameter, and the alternation of conductive and non-conductive threads leads to gaps in the formation of a solid fence.

Known signaling network for flexible fencing in a break-type signaling system, containing a knitted material having two layers, one of which is an electrically conductive grid that performs the function of an electromagnetic screen and is formed by loops only of conductive threads, and the second layer is formed by loops only of textile threads, non-conductive and completely overlapping yarns, using a standard knitted weave of varnished copper wire having a diameter of 0.3 mm and a density or mesh size of about 1 mm. Thus, the device includes parallel to each other independent first external non-conductive sheet or layer, the middle layer - a signal mat (i.e., the signal network itself), entirely consisting only of interwoven insulated electrically conductive threads, as well as a second external non-conductive sheet or layer ( RU 2126079).

The disadvantage of this technical solution is the complexity of the design, from separate layers of knitted electrically conductive wire and non-conductive base fabric, insufficient flexibility due to the use of threads (wires) of large diameter, limited ability to produce small-scale products.

Known signaling network for flexible fencing in a break-type signaling system, which is a cell made of an elastic thread and a conductive wire in insulation, located inside the warp threads. The network is formed by knitted weaving, in which the wire forms a single contour, the threads are made of highly shrinkable material. The high shrinkage material of the threads is selected from the group of polyamides, polyesters, polyethylene, polypropylene. The wire is stranded. Wire insulation is made of polyethylene, or Teflon, or fluoroplastic (RU 200854, prototype).

The disadvantage of this technical solution is the complexity of the design and operation of the signaling network from a conductive wire built into the thread of a non-conductive base, the complexity of the production of a special elastic thread of the base with an embedded insulated conductive wire, which requires an increased thickness of such threads and weaving a network with large cells exceeding 4 mm , which limits the possibility of its use in the manufacture of small-scale products and does not allow creating a continuous thin fence with a mesh size of less than 4 mm.

The technical problem to be solved by the present technical solution is to expand the arsenal and increase the efficiency of technical means, namely, signaling networks for flexible fencing in a break-type signaling system.

The technical result achieved through the use of the claimed technical solution consists in the implementation of the expansion of the arsenal and functionality of these means by creating an alternative design with high reliability and ease of use.

The signaling network for flexible fencing, which is a regular structure of cells of the joint knitted weaving of elastic warp threads and an insulated electrically conductive wire, which forms an electrical circuit sensitive to rupture, contains elastic warp threads and insulated electrically conductive wires, coupled to each other along their outer surfaces with the formation of double yarns and together woven into a fabric with a regular structure by knitted weave of said twin yarns.

The drawing Fig. 1 shows the structure of a single web of the signaling network of the kulirny weave; Fig. 2 is a diagram of the output of the signaling network status signal for its processing.

The signaling network for flexible fencing is a regular structure of cells of combined knitted weaving of elastic warp threads and an insulated electrically conductive wire that forms an electrical circuit that is sensitive to rupture. The signaling network contains elastic threads 1 of the warp and insulated conductive wires 2, tightly coupled to each other to their outer surfaces with the formation of double threads and together weaved into a fabric with a regular structure by knitted curly weave of these double threads. The signaling network preferably contains elastic warp threads 1 with a linear density of 70-160 tex. The signaling network preferably contains insulated conductive wires 2 with a diameter of 0.05 to 0.3 mm. The signaling network preferably contains elastic warp threads 1 and insulated conductive wires 2 woven into a web with a mesh size of 1-4 mm. The signaling network is preferably provided with a protective outer layer on at least one side of the surface of the web. The signaling network is made with the ability to connect through the contact plate 3 to the signal processing unit. The signaling net of the kulirny weave has loops located in the same row along the width of the knitted fabric, and form a horizontal loop row, and the loops, strung one on top of the other vertically, make up a vertical looped column. The signaling network as an electrically conductive wire 2 contains a winding wire with enamel fiber insulation or fiber insulation. The signaling network as an elastic thread 1 of the warp, it contains threads from the group: polyester, aramid, nylon, complex fiberglass, carbon fiber.

For the manufacture of the signaling network of a flexible fence using the technology of knitted (knitted) weaving of threads, the loops of the rows of a single fabric of a flexible fence are formed by successive bending of a double thread and strung one on top of the other. In this case, a regular structure of a single kulir (cross-knitted) weave of double threads with a size of loops (cells) of 1-4 mm, identical in shape and size, is formed.

Figure 1 shows the structure of a single fabric of the weave of threads 1 and wires 2 from the front side.

The loops located in the same row along the width of the canvas form a horizontal loop row, and the loops, strung vertically one on top of the other, form a vertical looped column.

When knitting, a double thread is used, consisting of an electrically conductive insulated wire 2 with a diameter of 0.05 to 0.3 mm and the main (polyester, aramid, nylon, complex fiberglass, carbon fiber) thread 1 with a linear density of 70-160 tex.

Thread 1 and wire 2 from their spool (bobbin), through tensioning devices, are simultaneously fed to the needle bar of the knitting machine.

The main thread 1 during knitting protects the small diameter electrically insulated wire 2 from accidental breakage. The resulting safety fence fabric has increased tensile strength and the formation of the finished signaling network. As a result of knitted weaving of thread 1 and wire 2 of the proposed signaling network, wire 2 does not break at the bends and in the corners, since the forming loops of thread 1 are equidistant (equidistant - parallelism or concentricity of curved lines) are conjugated with wire 2. As a result, wire 2 and thread 1 are interconnected in a single weaving, due to which the formation of network cells without a wire is excluded 2.

The formation of a network of conjugated conductive insulated wires 2 of small diameter and threads 1 of low linear density of the warp, their simultaneous supply to the needle bed of the knitting machine allows organizing the production of flexible fencing on semi-professional and industrial knitting machines of 5-7 classes.

A single sheet is produced on machines with one needle bed - single-line (single). In some cases, a single sheet can be obtained on double-flow machines, provided that one needle bed is used.

Thus, the signaling network is made of elastic jersey by weaving an eraser 1 + 1 from the simultaneously knitted elastomeric thread 1 of the warp and wire 2, similar in weave to the thread Lurex.

The eraser is a double cross-knit weave, in which the front columns of the surface alternate with the wrong ones on the front and on the wrong side of the fabric. The eraser weave pattern has the least dissolving. Lurex is a metal thread that is inserted into the structure of the warp (to create the effect of shine and luxury). It passes as an additional fiber (thread) intertwined with the threads of the base material. The web of the signaling network is provided with an elastic protective outer layer (not shown) on at least one side of the surface of the web.

After forming the finished web of the security fence signaling network, for example, an intrusion detection fence, a pair of leads of the electrically conductive insulated wire 2 is output to the signal processing unit through the contact plate 3 located between the security fence web and the signal processing unit.

The signaling network of a flexible fence in a break-type signaling system works as follows.

The network is mounted using supporting elements along the perimeter of the protected object, and the contour formed by wire 2 is connected via a contact board 3 to the signal processing unit (Fig. 2). To bring the fence into readiness, the specified circuit is supplied with voltage from an appropriate source, mainly a guaranteed power source.

In the absence of violations of the flexible fence, the resistance of wire 2 is the same over the entire area of the signaling network. In case of violation, i.e. if wire 2 is broken, a section of increased resistance occurs, i.e. rupture of the electrical circuit of the break-type alarm system. The signal processing unit monitors the resistance of the conductive wire 2 and, when it breaks, triggers the corresponding actuator (not shown), which gives a sound and / or light signal, and / or performs other protective actions that interfere with the goals of the intruder.

The signaling network is used in the specified system to inform and signal about unauthorized entry into the protected object, for example, to protect valuables, as well as to block the opening of locks, locking, etc. protective devices.

In this case, i.e. in the event of a breach of insulation, wire 2 remains reliable due to the fact that it is woven into elastic thread 1. Due to the use of loop (knitted) weaving in the proposed solution, wherever there are attempts to cut the network, the intersection of the contours cannot be bypassed, and, therefore, will be ensured reliable signal arrival at the guard post.

The proposed signaling network, due to its flexibility, can be easily integrated, if necessary, into protective circuits of various shapes.

Thus, as a result of the implementation of the claimed utility model, a continuous protective fence is created from an electrically conductive insulated wire of small diameter, an increase in the flexibility of the canvas, the possibility of an optimal choice of its resistance due to the use of electrically conductive wires of different diameters (i.e., the smaller the wire diameter, the greater the resistance canvas), the possibility of implementing an inexpensive small-scale production.
