Referring to Figure 1, the non-recessed loop coil module of the present invention (hereinafter referred to as 'the loop coil module 10 of the present invention') is a main housing 100 and a loop coil embedded in the main housing 100. is comprised of

The body housing 100 has an elastic material and a coil groove 101 is provided therein.

The body housing 100 can select any one of known elastic materials such as urethane, silicone, rubber, PVC (Poly Vinyl Chloride) material, and the loop coil installed in the coil groove 101 is installed in the vehicle (1). ) to protect it from being damaged by loads such as

The coil groove 101 is preferably configured so that no overlapping portion is formed so as not to affect the magnetic field formed by the loop coil.

In addition, the coil groove 101 includes a first coil groove and a second coil groove, and as shown in FIG. 2 , a space in which the coil wire 110 constituting the loop coil is wound is provided in the first coil groove. and a space in which the lead-in line 130 drawn in from the outside is placed is provided in the second coil groove.

At this time, the first coil groove and the second coil groove can be separated in position by forming a step difference between the first coil groove and the second coil groove in the inner space of the main body housing 100 as shown in FIG. 3 . In a portion where the first coil groove and the second coil groove are in contact with each other, a connecting space is formed to allow them to communicate, so that the coil wire 110 and the lead wire 130 can be electrically connected.

The main body housing 100 has a main body housing (100) by extending the lead-in pipe 103 communicating with the inner second coil groove on one side so that the lead-in line 130 is introduced into the second coil groove through the lead-in pipe 103. 10) so that the lead-in wire 130 exposed from the coil wire 110 can be protected in the same way.

The Sangli loop coil is installed so that one coil wire 110 is wound at least twice or more along the coil groove 101, and the coil wire 110 is connected to the lead wire 130 leading into the body housing 100. An operation signal is received.

Here, to briefly describe the operation mechanism of the loop coil, the coil wire 110 has an alternating magnetic field with uniform inductance by the operation signal applied from the lead-in wire 130 to form a vehicle ( 1) to form a sensing area that can detect In this case, the operation signal may be a current having a specific frequency band.

That is, when the vehicle 1 passes or stops above the magnetic field formed in the coil wire 110 , the magnetic flux between the vehicle 1 and the coil wire 110 changes, thereby changing the inductance of the coil wire 110 as well. As a result, the control unit that receives and analyzes the change in inductance of the coil wire 110 can detect the vehicle 1 .

Meanwhile, the coil wire 110 according to an embodiment of the present invention may be configured to be wound four times in the coil groove 101 .

Specifically, the coil wire 110 may be a VCTF (vinyl cap tire cord) wire in which four independent single wires are spaced apart from each other so that no twist occurs and are accommodated together in one covering, and disposed along the coil groove 101 . One end and the other end of the VCTF line to be used may be exposed in the connecting space to be connected to the lead-in line 130 .
