Description

one

The invention relates to the field of sports equipment, is intended to automatically record strikes and thrusts during fencing, and can be used to obtain objective information when conducting sports competitions in fingering.

A device for capturing blows and pricks during fencing is known, comprising electrocontact clothes and a signal device comprising a power source, fixation elements of actual and invalid blows and punches connected to the alarm unit 1.

 The disadvantage of such a device is the impossibility of distinguishing between real and invalid blows and injections during their registration and counting.

The aim of the invention is to increase the objectivity of fixing blows and shots by eliminating the consideration of invalid blows and shots, for example, of the “stroke” type.

This is achieved by the fact that the proposed device has contact sensors mounted in the body of the guns, and the signal device contains the elements for determining each weapon’s actual and invalid shots and shots, turning off the enemy’s weapons and delays, while one of the inputs for each element determining actual and invalid blows and injections through the power source are connected to electrocontact clothes, the second entrances are connected to contact enemy sensors, and the outputs through the delay elements are connected to the inputs of the fixing elements of real and invalid strikes and thrusts, the outputs of which are connected to the elements of the gun disconnection.

In addition, in order to obtain information about the unsecured protection and actions on the enemy's weapon, the signal device has a block of information electrically connected with the weapon and with electrical contact clothing and consisting of a deist- registration element. VIA on the weapon, the counter effect on the weapon and the detector, while the counter and the detector are connected to the registration element of the effect on the weapon and to the outputs of the fixation elements of valid and invalid punches and shots.

FIG. 1 shows an example of installing a sensor in the body of a gun (saber); in fig. 2 - schematic diagram of the device.

In the drawings, the following notation is used: 1 - saber body; 2 - grooves in the body of the saber for placement of contact sensors; 3 - contact sensor; 4 and 5, respectively, the surface of electrocontact garments is damaged and not affected, electrically insulated from one another; 6 - the element of determining the valid and invalid blows and shots; 7 - the element of disabling the enemy's weapons; 8 - delay element; 9 and 10 - fixation elements, respectively, valid and invalid shots and shots; 11 - information block; 12 - element of registration of action on the weapon; 13 - counter action on the weapon; 14 - warning device; 15 - alarm unit.

In the body 1 of the saber grooves 2 are made, for example, along the entire length of the blade, in the tip and in the area of the anti-blade adjacent to the guard. In the grooves 2, there are non-protrusions beyond the groove limits of the contact sensors 3, made, for example, in the form of flexible conductors of high mechanical strength and electrically isolated from the body 1 of the saber and guard.

Electrical contact clothing of each fencer has a striking 4 and an invisible 5 surface, connected with high conductivity wires through a power source to the input of the corresponding element 6 for detecting real and invalid shocks and thrusts, the second inputs of which are connected to the contact sensors through elements 7 of the enemy’s weapons and diodes connected to contact sensors 3 enemy weapons.

The connection to the non-invasive surface of electrical contact clothing and to the non-invasive surface of the weapon is made through high-resistance resistors R.

The outputs of each element 6 for determining actual and invalid impacts and injections are connected through delay elements 8, which serve to separate out strokes and injections of the stroke type on the contact duration of the arms and electrical contact clothing, to elements 9 and 10 of fixation, respectively, of actual and invalid impacts and injections, the outputs of which connected to the inputs of the alarm unit 15, the elements 7 of disabling the enemy's weapons, as well as to the counter 13 effects on the weapon and the signaling device 14 of the information block 11.

Contact sensors 3 are also connected to the element 12 of the registration of the effect on the weapon, the output of which is connected to the inputs of the detector 14 and the counter 13 of the action on the weapon.

Resistors R are selected with the same resistance values, many times greater than the resistance of the connecting lines, and the resistance included in the electrical circuit elements. Therefore, conditionally, here, and in the following, only the resistances of the resistors R are taken into account. 5 Elements 6 for determining the actual and invalid shocks and injections are adjusted to change the input voltage when the external resistance changes

chains R and. Q The device works as follows.

When an enemy fencer strikes (or shots) with a non-damaging weapon surface over an unaffected 5 surface of electro-contact clothing, an electrical circuit is closed, including an unaffected surface of the fencer's gun, an unaffected 5 surface of the electrocontact clothing of the enemy, resistor R of electrocontact clothing, power source, element 6 for determining real forces. injections, n. 3. contact element 7 disable enemy weapons, a diode and a resistor R guns.

In this case, the resistance of the circuit will be equal to R; ynb R + R 2R, which corresponds to an invalid impact (stab), therefore the signal from the element 6 for determining the real and invalid impacts and injections through the delay element 8 goes to the element 10 for fixing the invalid impacts and injections and on the alarm unit 15. When struck (or pricked) non-obstructive

 the surface of the weapon on the affected 4 surface of electrocontact clothes or the damaging surface of the weapon on the unaffected 5 surface of electrocontact clothes the resistance of the circuit will be equal to the resistance of only one resistor R (respectively gun resistor or electrocontact clothes), which also corresponds to an invalid impact (prick) and order the passage of signals will be similar to the case discussed above. If the blower (or shot) of the fencer

is made correctly - with the striking surface of the guns on the struck 4 surfaces of electrical contact clothing, the resistors R are not included in the electrical circuit and its resistance will be conditionally equal to zero (0).

At the same time, the signal from the element 6 for detecting valid and invalid strikes and shots through the delay element 8 goes to the fixation element 9 of the actual blows and shots, to the alarm unit 15, the signaling device 14, the action counter on the weapon, as well as to the weapon deactivation element 7, which opens its contact in the chain of weapons of the enemy.
