Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

First, in the bimodal tram to which the present invention is applied, various techniques are applied to perform an automatic driving, for example, automatic control of acceleration and deceleration and steering control centering on a driving track. The bimodal tram is driven around the reference line in the center of the track. In this way, the magnetic bar is embedded at regular intervals in the center of the track and the vehicle detects this magnetic signal. At this time, very precise lateral control is performed to follow the indicated reference line. In addition, the self-driving road is recommended for concrete-paved dedicated track, but may be a general asphalt pavement in addition to the general concrete pavement.

In general, road paving types are divided into asphalt concrete pavement (commonly referred to as asphalt pavement), which is soft, and cement concrete pavement (commonly referred to as concrete pavement), which is rigid.

Asphalt pavement is a pavement with a surface layer made by combining aggregate with a bituminous material. Generally, it is composed of a surface layer, an intermediate layer, a base layer, and an auxiliary base layer (including an antifreeze layer). Using large materials, the roadbed supports vertical and shear stresses caused by the wide distribution of the load transmitted from the upper layer during the action of the traffic load.The composition and thickness of each layer can maintain the mechanical balance and withstand the traffic load sufficiently. It is composed. Asphalt pavements are sometimes referred to as flexible pavements, focusing on the mechanical behavior of these pavements.

In addition, the concrete pavement is a pavement type in which the concrete slab itself behaves like a beam to support the stress generated by the traffic load with bending resistance. Such concrete pavement is generally composed of surface concrete slab and auxiliary base layer (lean concrete, granular material-frost prevention layer), and the role of auxiliary base layer gives the slab an equal bearing capacity and prevents frost heave as a permeable layer. It is responsible for creating a stable work base for pouring cement concrete slabs.

On the other hand, since the road surface of the driving track is a part where the load of the bimodal tram, which is the track vehicle, is in direct contact with the load, the load is concentrated. It is difficult to apply it as it is. For this reason, the surface layer portion is made of a concrete material having high rigidity, so that the pavement surface can be maintained without deformation even in the concentrated load of the vehicle. As such, the road pavement type of the bimodal tram according to the embodiment of the present invention is suitable for concrete pavement, asphalt pavement when installing a material that can reduce the occurrence of deformation on the pavement surface, or regularly repair the deformation part Applicable to

In addition, since the asphalt pavement is excellent in driving performance, when the asphalt pavement is applied to the road pavement type of the bi-modal tram according to the embodiment of the present invention, the deformation of the running part surface where the wheels of the bi-modal tram, which is the track vehicle, is allowed to be allowed. It can be applied as an asphalt pavement of thickness without departing from the range. At this time, the thickness of the asphalt pavement layer is selected by applying the appropriate thickness of the asphalt pavement layer so that the deformation of the asphalt layer is within a certain allowable range in consideration that the surface is easily deformed by the load of the track vehicle when the track vehicle is running. It is desirable to. As such, by installing the asphalt pavement layer on the upper surface of the concrete running part, it is possible to secure the running performance superior to the concrete pavement surface when the track vehicle runs.

Hereinafter, as an embodiment of the present invention, a method of installing a magnetic bar, which is a precision induction device used in a track of a bimodal tram for controlling the operation of a bimodal tram, will be described. In this case, a positioning method and a position for installing the magnetic bar The adjustment method is additionally described. In addition, the magnetic bar can be installed on the asphalt pavement, concrete pavement, pavement of the bridge deck, the support and positioning device for fixing and precise installation of the magnetic bar and concrete block filled with epoxy and the like are specifically illustrated.

FIG. 7 is a diagram illustrating a general track concrete (or asphalt) pavement to which an embodiment of the present invention is applied and shows a general track concrete (or asphalt) 104a and a magnetic bar 105 installed on the general track concrete.

On the other hand, Figure 8 is a diagram illustrating the size and shape of the magnetic bar according to an embodiment of the present invention, showing a magnetic bar provided on a test line.

Referring to FIG. 8, the size and shape of the magnetic bar 105 according to the embodiment of the present invention is based on a circular magnetic bar 105 having a diameter of 1.5 cm and a height of 3.0 cm as a standard, and can be easily installed in a package of a line. In addition, any size and shape can be used as long as the sensor satisfies the strength capable of sensing the magnetic field. For example, the shape of the magnetic bar 105 may be triangular, square, pentagonal, hexagonal or spherical.

Positioning method for the installation of the magnetic bar according to an embodiment of the present invention is as follows.

First, in order to determine the lateral position of the magnetic bar, one magnetic bar line is applied to each line, and two magnetic bar tracks are applied to the bidirectional line. In general, it is standard that the magnetic bar is located at the center of the track width, but it can be installed so as to be located at the width of the magnetic bar sensor installed on the lower surface of the vehicle according to the cross-sectional condition, other magnetic field conditions, and construction conditions. For example, the magnetic bar may be installed within the sensor width of 1.65 m in consideration of the transverse driving error during driving.

In addition, the magnetic grid of the magnetic bar must have a smooth line, which is installed so that the magnetic bar sensor in the leading lower part of the bimodal tram passes through the center. In addition, the magnetic grid is installed in the center of the line in the straight section and the gentle curve section of the track. In addition, the dotted line of the magnetic bar should be located within the range specified with respect to the straight line and the gentle curved portion on the right side. In addition, the right side of the line is determined not by the right boundary line but by the physical curve condition on the right side.

Next, the longitudinal distance between the magnetic bars in the section between the station and the station other than the initialization is determined as follows. First, maintain the specified distance between each magnetic bar in the longitudinal direction, for example 4.5 m ± 1.0 m, and if necessary within a permitted deviation from the specified distance (nominal value 4.5 m), for example 1.0 m. Determine the longitudinal distance. In other words, the installation of the magnetic bar in the normal driving section is the vertical continuous distance between the magnetic bars that can safely drive the vehicle while sensing the magnetic bar by the magnetic bar sensor. Under the condition that the longitudinal continuous distance between the magnetic bars can be changed. In addition, the installation of the magnetic bar in the curved section is based on the change of the distance between the magnetic bars from 4.5m to 1.0m according to the length of the radius of curvature, and the longitudinal continuous between the magnetic bars under the condition of maintaining driving safety The distance can be changed.

In addition, the distance between the magnetic bars in the initialization section of the driving start point is to install 11 magnetic bars consecutively at intervals of at least 1.0 m and at most 1.3 m in order to configure the initialization code, and when the initialization code can be configured at the initialization section, the magnetic bars The number and spacing of can be changed. In this case, a distance of at least 20 cm from the ferromagnetic steel should be provided.

Next, the magnetic bar installation pattern and polarity of the sections other than the initialization are as follows. First, magnetic bars in sections other than initialization (section between station and station) are installed with random polarity. At this time, it should start with the first with reference to the provided magnetic bar installation list and position the polarity of the magnetic bar according to the pattern of the list. In addition, the number of magnetic bars used in the magnetic bar installation list is entered, and in the new section, the positions of the last bars are continuously determined in a random list order.

Next, the position of the magnetic bar in the initialization section is determined as follows. First, the starting point position of the initialization section is 110m before the starting point of the station platform, and the starting point of the magnetic bar at the station is the beginning of the horizontal part of the platform. At this time, the magnetic bars of the initialization section is composed of 11, the prescribed distance between each magnetic bar, for example, must comply with, for example, 1m ~ 1.3m. In addition, the initialization section and the section other than the initialization should be connected smoothly. It is also possible to adjust the position within permitted deviations, for example 0.3 m, in order to avoid ferromagnetic objects if necessary. In addition, the magnetic bars should be spaced apart from the ferromagnetic objects in the road structure by a minimum distance, for example at least 20 cm. At this time, the installation position of the magnetic bar in the initialization section may use a unique list provided according to the characteristics of each bimodal tram stop.

Next, when the magnetic field of geomagnetic field, rock magnetic field, artificial facility magnetic field (concrete, asphalt, reinforcing steel, steel, magnets other than the purpose of installation), and other materials appear at the location where the magnetic bar is installed, Avoid the spot and select the installation location of the magnetic bar. In addition, when measuring magnetic field other than magnetic bar, if it is more than 1.0gauss on the line pavement surface about 15cm, the magnetic bar is not installed at that position and if it is less than 1.0gauss, it is standard to install the magnetic bar at that position. If the sensing of the magnetic bar is possible and the driving safety is verified regardless of the strength of the magnetic field other than the magnetic bar, the 1.0gauss magnetic field measurement standard other than the magnetic bar may be changed.

On the other hand, a bi-modal tram-only vehicle according to an embodiment of the present invention is called a track that is driven by the magnetic field of the magnetic bar to run the track, when used in combination with a general vehicle (general track), bimodal tram vehicle However, when driving exclusively, it is classified as an exclusive track. Therefore, the general track may be constructed of general pavement (concrete or asphalt pavement), and the dedicated track may be constructed of general pavement and track type pavement (concrete or asphalt pavement).
