Description

An encoded information device on an infrastructure that will be decoded by a sensor positioned on a mobile device

The present invention provides an encoded information device located on an infrastructure that will be decoded by sensors positioned on a mobile device such that the devices encode their location in the infrastructure and allow for travel along the same trajectory And the mobile device provided with the appropriate sensor reads, decodes and immediately converts information about its exact location in the infrastructure. These coded information devices in particular allow them to be used in automated guidance systems on all types of mobile devices traveling along the infrastructure, such as cars, trains or even waterway vehicles. The field of the invention is the automotive auxiliary industry, the train industry, and the electronics industry.

There are prior art devices for performing the same function of encoding information, which can be located on the infrastructure.

From among these, the inventors are similar to the inventors of the international patent PCT/ES2015/070378, in which the coding device is described as a guide rail mounted flush with the road surface, but it can also preferably be hidden in the asphalt road layer. Hereinafter, it is treated with a layer of hydrophobic material, and has a preferred size of 1.5 cm wide and 5 cm deep, wherein the inside has a machining chamber, and the preferred shape of the chamber is a dihedron due to the plane of the dihedron. The reflected signals can be increased, thus enabling them to be detected.

The device is effective for some infrastructure, but it does not allow for the development of all the possibilities offered by the system, for which reason the present invention proposes to present other new devices that are particularly well suited to all types of infrastructure present, while Simpler (eg, discontinuous, economical) devices that encode information, such as paint marks, are also provided.

For the inventors, there are no known prior examples including the proposals made by the present invention, or the advantages implied by such proposals.

In view of this, our inventors are concentrating on further research on the coded information device on the infrastructure that will be decoded by the sensor located on the mobile device, and proceed with research and development and improvement, with a better design to solve the above. The problem, and after continuous testing and modification, has the invention.

In order to achieve the above objectives, our inventors provide a coded information device that is located on the infrastructure and that will be decoded by sensors positioned on the mobile device, such that the devices encode their location in the infrastructure. And allowing mobile devices traveling along the same trajectory and equipped with appropriate sensors to read, decode, and immediately convert to information about their exact location in the infrastructure.

In particular, these coded information devices allow them to be used in automated guidance systems on all types of mobile devices traveling along the infrastructure, such as cars, trains or even waterways vehicles.

Information is provided by detecting changes in the dielectric properties of devices located in the infrastructure, wherein the dielectric changes are detected by means of a sensor, such as a high resolution radar device or another similar detector.

In the entire trajectory of the mobile device operation, information in the infrastructure can be encoded by means of different objects having different dielectric height boundaries or distances at different heights or distances from the beginning of the loaded sensor. Electrical/metal boundary.

The boundaries are interrogated by the sensor loaded on the mobile device by means of pressure waves or electromagnetic waves, and by measuring the time it takes for the wave to return to the sensor, the distance at which the reflection occurs can be determined and Way to extract information.

Different devices can be distinguished as follows:

The information devices for these characteristics relate to the information given by the track sleepers because of the unique characteristics of the track sleepers:

- a uniform surface of the ballast, or

- different heights of the tracks set on the concrete slab,

The sleeper is always found at a certain distance from a known point on the locomotive (one or more) or a truck (car).

Moreover, these sleepers can be coded with a series of bits by means of a series of studs of different heights, the sleepers being coded by a series of studs that provide a range of levels, the studs being of a known thickness Covered by wave-transparent materials.

The information about the location is divided into groups of four bits, which are successively coded in each sleeper by level.

When encoding two consecutive bits having the same level, the third level of the different height is used to encode the repeated second bit.

This technique allows the sensor to recognize two bits and determines that the second bit has the same logic level as the previous bit.

By alternately using the repetition level, successive four-bit strings having the same logic level can be identified.

The fourth height level is always used as the fifth bit.

In this way, the sensor is able to know the reading direction.

If the first detection matches the fourth level, the sensor will detect that it reads the bits in reverse order.

The four-bit information can get 2 ⁴ = 16 different sleepers, each of which encodes five bits (four-bit information, one bit indicates the reading direction).

The seventeenth sleeper model is characterized in that its first bit starts with a repeating bit and its fifth bit indicates a reading direction, and the seventeenth sleeper model is used to indicate the start of a message consisting of a four-bit bit group or End.

In this way, the message starts the sleeper and the eight more sleepers of the information can encode 232 possible combinations that can be uniquely assigned to the segments occupied by the nine sleepers.

The information is encoded in two different places in a redundant manner, enabling the two sensors to simultaneously read the information device.

The sensor interrogates the infrastructure with a spot of 8 mm in diameter, in order for the sensor to properly illuminate each stud, the surface area of the stud is 1 cm ² , and the height of each peg associated with a different logical level is 0.5 Cm.

These studs are covered by a wave-transparent material (2) of known thickness and have two functions: on the one hand avoiding the deposition of any material between the studs and also serving as a reference to determine different logic levels.

The locomotive or passenger car can change its height due to the effect of the suspension, but, assuming that the sensor detects reflections in the boundary between the wave-transparent material and the air, this can determine different logic levels independently of the distance from the locomotive to the ground. s position.

Another information device is still a sleeper, but in the sleeper, the information is coded with cracks instead of pegs so that there is no relief on the upper surface of the sleeper.

The stud or crack technique described can also be used on rails placed on concrete slabs.

Another information device is a code block, but they are mounted on the side or upper side of the track (for example, on a suspension chain, on a platform or an arch of a tunnel, etc.), and are rotated so that their coding portions face The sensor is also arranged at a particular height such that there is also a direct field of view between the sensor and the coded block even under snow conditions.

The boundary surface is capable of forming a trihedron to maximize reflection.

If the information needs to be used for terrestrial infrastructure, more specifically roads, then a series of granules/lines of paint or another material can be expected to be preferably black so as not to confuse the driver.

Particle blocks exhibiting different thicknesses have a 2 mm spacing between the boundaries and stick to the center/lane of the road in the longitudinal direction.

These granules each have a surface area of 1 cm ² and have an overcoat composed of another permeable material having hydrophobic properties, the upper coating serving as a reference point for the sensor.

The information can also rely on different horizontal codes with 3 mm spacing, which are a four-bit group plus a fifth bit indicating the reading direction.

There is a free uncoded space between the five-bit blocks, causing the water to slip along the slope marked by the road arch, so water does not accumulate near the information device.

Along with a series of particle blocks, two side strips having different thicknesses are used to encode the lateral drift of the information device to which the sensor is encoded relative to the information.

Another information device consists of strips having cracks of different depths, preferably of plastic, which are coded per centimeter.

Among other applications, the strip can be used to inform the mobile device of the advancement and position such that it can apply controllable acceleration and deceleration, thereby enabling the mobile device to be accurately stopped.

An example can be that the train stops at the platform.

Another way to encode information includes using objects of the same thickness (continuous or discontinuous), and the objects can be transmitted by waves with different transmission properties with respect to propagation speed.

In the case of electromagnetic waves, different dielectric constants will be more or less delayed in detection associated with the second dielectric change boundary (the back side of the object).

Another information device is characterized in that it has a covering surface which is composed of a material having a different wave propagation speed.

This fact causes (when a constant propagation speed is considered) to detect the upper boundary of the separation in a different manner than the post-detection boundary.

Another information device is characterized in that it has a coating composed of a material having a different wave propagation speed, and therefore, when considering a constant propagation speed, there is a difference between the detection of each boundary. Such a block is different from the corresponding lower block, causing the detection of the upper boundary to be different from the detection of the lower boundary depending on the material used.

A scheme is proposed to enable reading of encoded information on a non-conductive material by virtue of the presence or absence of a dielectric constant change boundary in the middle, which can be detected by means of a sensor mounted on the mobile device.

The dielectric change boundary in the non-conductive material causes a portion of the energy that is illuminated toward the material in question to be reflected.

The energy of the reflection is detected by an associated sensor so that the radial distance at which the interruption occurs can be determined.

A dielectric change boundary can be obtained by using two materials or substances having different dielectric constants, or using a single material, establishing a boundary between the single material and a vacuum or with a material or a gas or a substance.

The invention will be described in detail below with reference to the drawings.

Referring first to Figures 1 through 4, the present invention is an encoded information device on an infrastructure that will be decoded by sensors positioned on a mobile device such that the devices encode them in the infrastructure. The occupied location and allows mobile devices traveling along the same trajectory and equipped with appropriate sensors to read, decode, and immediately convert to information about their exact location in the infrastructure.

These coded information devices in particular allow them to be used in automated guidance systems on all types of mobile devices traveling along the infrastructure, such as cars, trains or even waterway vehicles.

Information is provided by detecting changes in the dielectric properties of devices located in the infrastructure, wherein the dielectric changes are detected by means of a sensor, such as a high resolution radar device or another similar detector.

In the entire trajectory of the mobile device operation, information in the infrastructure can be encoded by means of different objects having different dielectric height boundaries or distances at different heights or distances from the beginning of the loaded sensor. Electrical/metal boundary.

The boundaries are interrogated by the sensor loaded on the mobile device by means of pressure waves or electromagnetic waves, and by measuring the time it takes for the wave to return to the sensor, the distance at which the reflection occurs can be determined and Way to extract information.

Different devices can be distinguished as follows:

A) Information devices with these characteristics we call type a), which involve information given by rail sleepers (T), because these railway sleepers present several unique characteristics:

- a uniform surface of the ballast, or

- different heights of the tracks set on the concrete slab

It was found that the sleeper (T) is located at a certain distance from a known point on the locomotive or a truck (car).

Moreover, as shown in Figure 1, these sleepers can be encoded with a series of bits by means of a series of studs of different heights.

The coding of the sleeper (T) is performed by a series of studs that provide a series of levels (3, 4, 5, 6) and which are covered by a wave-transparent material (2) of known thickness.

The information about the location is divided into groups of four bits, which are successively coded in each sleeper by level (3, 4).

When encoding two consecutive bits having the same level, a third level (5) of a different height is used to encode the repeated second bit.

This technique allows the sensor to recognize two bits and determines that the second bit has the same logic level as the previous bit.

By alternately using the repetition level, successive four-bit strings having the same logic level can be identified.

The fourth height level (6) is always used as the fifth bit.

In this way, the sensor is able to know the reading direction.

If the first detection matches the fourth level, the sensor will detect that it reads the bits in reverse order.

The four-bit information can get 2 ⁴ = 16 different sleepers, each of which encodes five bits (four-bit information, one bit indicates the reading direction).

The seventeenth sleeper model is characterized in that its first bit starts with the repeating bit (5) and its fifth bit (6) indicates the reading direction, and the seventeenth sleeper model is used to indicate the bit group by four bits. The beginning or end of the composed message.

In this way, the message starts the sleeper and the eight more sleepers of the information can encode 232 possible combinations that can be uniquely assigned to the segments occupied by the nine sleepers.

The information is encoded in two different places in a redundant manner so that the two sensors can simultaneously read the information device.

The sensor interrogates the infrastructure with a spot of 8 mm in diameter.

In order for the sensor to properly illuminate each stud, the surface area of the stud is 1 cm ² .

The height of each stud associated with a different logical level is 0.5 cm.

These studs are covered by a wave permeable material (2) of known thickness.

The coating has two functions:

On the one hand, any material is prevented from depositing between the studs and is also used as a reference to determine different logic levels.

The locomotive or passenger car can change its height due to the effect of the suspension, but, assuming that the sensor detects reflections in the boundary between the wave-transparent material and the air, this can determine different logic levels independently of the distance from the locomotive to the ground. s position.

B) Another information device, which we will refer to as type b), is a sleeper in which information is encoded with cracks rather than with pegs such that there is no undulation on the upper surface of the sleeper.

C) Another information device we will refer to as type c), including the use of studs or cracking techniques on rails placed on concrete slabs.

D) Another information device, which we will refer to as type d), refers to a coded block coded in a manner similar to type a) that is mounted only on the side or upper side of the track (eg, mounted on a hanging chain, month) Or the arches of the tunnel or the like, are suitably rotated such that their coding portions face the sensor and are arranged at a particular height such that even under snow conditions the sensor and the code block are also There is a direct view.

The boundary surface is capable of forming a trihedron to maximize reflection.

E) Another information device, which we will refer to as type e), is an information device similar to type a) that is used only on the road rather than on the sleeper.

In this case the stud is a series of granules/wires made of paint or another material, which is preferably black in order not to confuse the driver.

The granules have different thicknesses and have a 2 mm spacing between the boundaries and are glued longitudinally to the center/lane of the road.

Figure 2 shows a section of the wear layer of the road (7) and one of the particle blocks.

These granules each have a surface area of 1 cm ² and have an overcoat consisting of another permeable material with hydrophobic properties, the upper coating serving as a reference point for the sensor.

The information is also encoded by three different levels (9, 10, 11) with a 3 mm interval, and a fifth bit (12) indicating the reading direction is added to the group.

There is a free uncoded space between the five-bit blocks, causing the water to slip along the slope marked by the road arch, so water does not accumulate near the information device.

Along with a series of particle blocks, two side strips (13, 14) having different thicknesses are used to encode the lateral drift of the information device to which the sensor is encoded relative to the information.

F) Another information device, referred to as type f), consists of strips having cracks of different depths (having a level defined by type a), preferably of plastic, and encoded per centimeter.

Among other applications, the strip can be used to inform the mobile device of the advancement and position such that it can apply controllable acceleration and deceleration, thereby enabling the mobile device to be accurately stopped.

An example can be that the train stops at the platform.

G) Another way of encoding information, we call type g), involves the use of objects of the same thickness (continuous or discontinuous) that are capable of being transmitted by waves and having different transmission properties with respect to propagation speed.

In the case of electromagnetic waves, different dielectric constants will be more or less delayed in detection associated with the second dielectric change boundary (the back side of the object).

H) Another way of encoding information according to Figure 3 is we call type h), including the same device as type a), except that the information is not about the depth of the material used as the coating, but because of the coating The layers are composed of materials (15, 16, 17) having different wave propagation speeds.

This fact causes (when a constant propagation speed is considered) to detect the spaced boundaries (18, 19, 20) in a different manner than the detection boundaries (20, 21, 22).

J) Another information device we call type j), which is the same as defined in type e), except that the information is not the thickness of the coating (8) but the coating (8), which is propagated by the wave. Different materials are constructed, so there is a difference between the detection of the boundary considering the constant propagation velocity.

If we consider three blocks (23, 24, 25) that are parallel to each other and perpendicular to the axis of movement of the mobile device, then the upper boundary (26, 27, 28) of the block and the corresponding lower boundary (depending on the material used) The difference in position between 29, 30, 31) causes the detection of the upper boundary to be different from the detection of the lower boundary.

A scheme is proposed such that the encoded information on the non-conductive material can be read by virtue of the presence or absence of a dielectric constant change boundary in the middle, and the dielectric constant change boundary can be detected by means of a sensor mounted on the mobile device.

The dielectric change boundary in the non-conductive material causes a portion of the energy that is illuminated toward the material in question to be reflected.

The energy of the reflection is detected by an associated sensor so that the radial distance at which the interruption occurs can be determined.

A dielectric change boundary can be obtained by using two materials or substances having different dielectric constants, or using a single material, establishing a boundary between the single material and a vacuum or with a material or a gas or a substance.

In summary, the technical means disclosed by the present invention can effectively solve the problems of the prior knowledge, achieve the intended purpose and efficacy, and are not found in the publication before publication, have not been publicly used, and have long-term progress, The invention referred to in the Patent Law is correct, and the application is filed according to law, and the company is invited to give a detailed examination and grant a patent for invention.
