Definitions
- an electromagnetic traffic signal detection system having one or more detection loops comprising a pre-shaped electrically conducting material in one or more loops of a predetermined shape.
- an assembly of a geotextile base bandage impregnated with bitumen and having electric conductors secured thereon by a protective tape is placed on a layer (road pavement base) of the road surface.
- the assembly is secured to the layer of the road surface by means of a bituminous strip. After that a bitumen surface layer is applied. It is indicated that this method can be used at temperatures over 100°C, but temperatures below 80°C are preferred.
- the cable may comprise several conductors that directly abut one another, particularly are stranded.
- the coating of the singular wires in each conductor can provide sufficient insulation between the conductors one to the other.
- the several conductors for instance seven can be connected in series. In that way a plurality of windings is provided within the cable. By choosing the number of windings the desired sensitivity of the detection loop can be set. Furthermore, if not all conductors within the cable are used, in case of a conductor that is indeed used being damaged it can be replaced by a conductor that had been free up until then.
- the height of the device can be kept limited, which is advantageous when the device comes to lie directly underneath the covering layer of the road surface.
- the connecting sections may extend with a portion to beyond the carrier and at that location preferably be rolled up.
- the invention provides a detection loop for a road surface, particularly an asphalt road surface, comprising a strip-shaped carrier with an electric conductor attached thereto, which have been put in the desired loop shape in advance and are suitable to be attached to a sub layer of the road surface, before the top layer of the road surface is disposed over it, wherein the conductor is attached to the carrier in advance in the desired configuration, which carrier is formed by a strip of open fabric impregnated with a resin, and the conductor consists of a multiple core cable, which on the outer circumference is provided with a sheath able to absorb high temperatures and high tensile forces, and each core is provided with its own ceramic insulation so that a loop of several windings can be formed.
- the carrier 1 is provided with a detection loop 5, which is formed by a cable 6 attached to the carrier 1 by means of cable binders 8, which as can be seen in the schematic depiction of figure 2A , have been arranged around the cable 6 and a grid element 2 and/or 3, for instance every 10 cm.
- the cut-off end 8b projects as little as possible from its locking end 8a.
- the cable binders can be TY-RAP® TYB 24MX.
- the locking end 8a sits adjacent to the cable 6 so that the height of the carrier with cable remains limited and is not significantly increased by the cable binders.
- the cable may have a diameter of approximately 6 mm
- the cores 13 may have a cross-sectional surface of for instance 0.5 to 0.9 mm 2 , for instance 0.5 mm 2 .
- the heat-resistant coating, having a thickness of for instance 10-12 micron, on the singular wires may be a lacquer that has been hardened on the singular wires in an oven.
- Such a lacquer is known per se from singular wires in transformer coils, such as for round lacquered copper coil wire, heat class 200°C. Also see the so-called enamelled (copper) wire.
- the singular wires and the cores/litze wires stranded therefrom remain sufficiently bendable despite the lacquer. It can be permitted here that at bending of the cable the cores/litze wires or the singular wires slide along each other without the insulation between the cores/litze wires getting noticeably damaged.
- the cable 6 is attached to the carrier 1 in the plant, wherein terminals 7a,b are disposed on the entry/exit parts of the cable 6, the so-called loop supply cables or connecting sections 9', 9".
- the connecting sections 9',9" may have a length adjusted to the work in question, for connection to a loop coupling box, for instance several meters and subsequently have been rolled up in the plant.
- the device 10 thus obtained - with the loop on the concave side- can be rolled up in direction X, with the axis of the roll in direction Y, and then be stored, and also be transported to the work in that condition.
- the carrier 1 can also be rolled up in direction Y.
- the carrier 1 can be rolled up onto itself (particularly in case of larger lengths) or on a piece of tubing (particularly in case of smaller lengths).
- a sticky adhesive layer is subsequently applied over the asphalt (concrete) layer 21 and over the device 1, after which by means of an asphalt paver 130 the asphalt top layer 22 of the road surface is laid, see figure 4C .
- the paver 130 then moves in direction X, parallel to the grid elements 3.
- the road surface 100 with drive surface 22a, figure 4D is now ready and the connecting sections 9',9" can be connected to a connection box, not shown, by means of terminals 7a,b.
- the grid-shaped carrier 1 here ensures for the dimensional stability of the loop, and also provides local reinforcement of the asphalt.
- the combination of smaller diameter of the cores and the heat-resistant coating, particularly lacquer, of the thinnest conductive parts, the singular wires, with the selected materials render the cable particularly suitable for use as detection loop, particularly directly underneath a top layer in the road surface. Due to the high position a (highly) reliable signal can be obtained. However, it is also possible to position the loop deeper, as several cores, if deployed, form a coil, as a result of which the sensitivity of the detection loop is increased and a reliable signal is obtained despite the larger distance to a vehicle to be detected.
- the devices 110a-d can be supplied in double rolled up condition, wherein, the main surface of the carrier 101a-d is rolled up in direction X and the projecting portion 119a-d in a direction transverse thereto.
- first device 110a is rolled out and adhered to the freely exposed asphalt surface.
- device 110b follows, wherein the projecting portion 119b connects to carrier 101a.
- device 110c follows, wherein the projecting portion 119c connects to carrier 101b.
- device 110d follows, wherein the projecting portion 119d connects to carrier 101c.
- the projecting portions 119a-d differ in width with a differing distance between the connecting sections 109a, 109b, 109c and 109d, so that the connecting sections 109a-d can sit next to each other and the assembly thus obtained remains limited in height.
- the connecting sections 109a-d jointly exit, situated together, for connection to a loop coupling box, for instance placed in the verge of the road.
- the grid size is many times larger than it will actually be (for instance 2.5 cm).
