DESCRIPTION

Invention Title

Marker sensor

Technical Field of the Invention

The present invention describes a marker sensor based on the effect of mutual ability. The sensor is suitable for counting the score in different sports, especially for counting the score in the paddle.

Background of the invention

In recent years, games of different sports have been popularized (paddle, tennis, basketball) among fans. The score in these matches is carried out by the players themselves when a referee does not participate in the match. The score must be done by heart because pointing the marker would delay the development of the matches

Object of the invention

The problem solved by the invention is to find a method for counting the score in ball sports that is fast, reliable, that does not interfere with the game and is resistant to impacts.

The solution found by the inventors is the marker sensor described in the claims, based on the capability-mutual effect. The sensor consists of a box, which is attached to a crystal. When the sensor is used to account for the score of a paddle match, the box is placed behind the glass of the track.

The inside of the box contains three plates:

- A printed circuit board that forms a square mesh,

- An intermediate plate of a dielectric material,

- A printed circuit board coated the entire copper face

Detailed description of the invention

The described sensor is formed by a box (2) of a plastic material such as PVC, ABS or PLA

Inside the box the following plates are introduced, which are in contact with each other:

- an electronic circuit board (1) that forms a square mesh with separations between 4 and 6 mm, in a preferred way the separation is 4 mm. a plate of a dielectric material (3) with a thickness between 0.8 and 1.2 in a preferred way the thickness of the plate (3) is 1 mm.

- an electronic circuit board (5) with an all copper face, which forms the non-active or reference part

As is known to those skilled in the art, electronic circuit boards (PCBs) are made of fiberglass or bakelite.

The box (2) is attached to a crystal (4) by the face of the electronic circuit board (1), which is the active face

The fixing of the box (2) to the glass (4) is carried out by methods known to the person skilled in the art, for example, by silicones

Preferably, the glass (4) has a thickness between 10-12 mm. This thickness is used in paddle courts. When the hand is brought closer to the glass, the marking is activated and the counting is carried out.

The sensor is coupled with a microprocessor (6) with wi-fi module (7) and a power supply (8).

The active plate (1), with the mesh, and the reference plate (5), covered with copper, have legs where two wires are welded that connect the two microprocessor connections (6) with the wi-fi module (7). The intermediate plate (3) of dielectric material is not connected to the microprocessor (6) with wi-fi module (7).

In a preferred mode, the microprocessor (6) with wi-fi module (7) is a commercial NodeMcu® board

A computer program is implanted in the microprocessor. The computer program is responsible for:

Make an automatic gain control at the beginning of the program to determine the noise

- Read the normal capacity of the sensor plates.

Decide the trigger level, reducing ambient noise

Increase a point by contact for a time less than one second Decrease a point by contact for a time greater than one second.

- Establish a wi-fi connection with phones, cameras or screens Detect and execute new program updates.

The power supply is a commercial 5 V / 200 mA power supply

The described system can be connected by means known to the person skilled in the art to screens, mobile phones, wireless cameras, etc.

The sensor described in the invention is suitable for counting in any game, such as squash, paddle, tennis, basketball, handball, etc.

In a preferred mode, the described system is intended to account for the score in the paddle, so the points are 0, 15, 30 and 45

Example

Two sensors were manufactured for a suitable marker for paddle counting with the following characteristics

- A printed circuit board (1) made of fiberglass that forms a square mesh with 4 mm separations,

A plate of a dielectric material (3) with a thickness of 1mm,

- A printed circuit board (5) made of fiberglass and coated

5 completely with copper,

- A NodeMcu® commercial board, which contains a microprocessor (6) and a wi-fi module (7) in which it implemented a computer program,

- A power supply (8) of 5V / 200 mA,

- A plastic box (2) PVC container.

The sensors were fixed with silicone on the crystals (4) of a paddle court, a sensor on each side of the track. The sensors were located on the outside of the track, so that they did not interfere in the game.

The crystals of the paddle court were 12 mm thick 15 The sensors were activated by bringing the hand closer to it
