DE10129434A1 - Contact recording device e.g. for use in sport of fencing, has flat electrical contact worn on body coupled via electronics to electrical contact in contact with background covered by conducting coating and contact on object - Google Patents

Abstract

The device has an internal power supply that enables an electronic counter to be controlled by the current occurring when contact is made. A flat electrical contact (1) is worn on the body and is coupled via evaluation electronics (2) to an electrical contact (3) in contact with a base covered by a conducting coating (6) and is electrically coupled to an electrical contact (4) mounted on an object.

Description

The invention relates to a touch registration device with its own Power supply.

It is known to use touch registration devices to register the Number of hits in martial arts, such as B. fencing to use.

Here, usually two opponents meet, their protective suits with Pressure sensors are equipped that have a touch on the part of the opposing Register the weapon with the resulting pressure.

The different parts of the body each have their own sensors assigned to localize the point of contact over the To enable registration facility.

Such devices are in particular from the fencing tournaments Olympiad known.

However, the registration device implemented in this way is expensive and light susceptible to interference.

In addition, the counterparties are usually on lines with one Registration electronics connected, which limits their freedom of movement and is particularly unsuitable for group encounters.

The invention specified in claim 1 is based on the problem an inexpensive, reliable, wear-resistant and that simultaneous interaction of multiple people Create registration facility.

This problem is solved by the features listed in claim 1 solved.

The advantages achieved by the invention are in particular that a in the manufacture of inexpensive registration device is created which only one, when the opponent's weapon touches the person flowing, current must register.

The electronic effort required for this is minimal because it is necessary in the simplest case only one voltage source, as well as various passive electronic components.

The making of a suit with electrical on the surface Contacting is correspondingly easy, since in the simplest case it is more conventional Wire mesh can serve as a coating.

An advantageous embodiment of the invention is in claim 2 specified.

The further development according to claim 2 enables several contacts isolated from each other, a rough local determination of the Point of contact.

An embodiment of the invention is shown in the drawing and will described in more detail below.

Show it

Fig. 1 is a diagram of the arrangement of electrical contacts on a touch registration device according to the invention, and their electrical coupling to each other.

Fig. 2 is a diagram of the arrangement of the electrical contacts of the touch registration device, as well as their electrical coupling to each other, wherein in comparison to Fig. 1 several contacts are attached to the body as an example, each having its own input in the electronic registration circuit.

An embodiment of the touch registration device according to FIG. 1 consists of a full-body suit made of fabric, on the outer surface of which a wire mesh ( 1 ) is attached, this being via the evaluation electronics ( 2 ) with a piece attached to the shoe sole Wire mesh ( 3 ) is electrically connected. In the present example, the electronics consist only of a resistor and a voltage source in series. A stick, which is also covered with a wire mesh ( 4 ), serves as a firearm. The wire mesh ( 4 ) is in turn connected to the wire mesh ( 3 ) by means of a cable. The floor is adequately designed with wire mesh ( 6 ).

The mode of operation will be explained using a fight between a player 1 and a player 2 .

Both players are on the wire mesh ( 6 ) laid out over the floor.

Now, if the player 1 clad with wire mesh (4) touches the bar grating (1) of player 2, the circuit of the voltage source is closed by players. 2

At the resistance of the electronics ( 2 ) of player 2 , a voltage drops, which for further signal processing, for. B. control a counter, can be reused.

Claims (2)

1. Touch registration device with its own power supply, which makes it possible to control an electronic counter, characterized by the current flow that occurs upon contact
a surface-mounted electrical contact ( 1 ) attached to the body, which is coupled via evaluation electronics ( 2 ) to an electrical contact ( 3 ) touching the substrate covered by a conductive layer ( 6 ), and
an electrical contact ( 4 ) arranged on an object, which is galvanically coupled to the contact ( 3 ). 2. Touch registration device according to claim 1, characterized in that a plurality of flat electrical contacts ( 5 ) are arranged on the body, these being coupled to the contact ( 3 ) via the correspondingly modified evaluation electronics ( 2 ).
