Description

The present invention relates to sports equipment, namely, devices for monitoring the execution of a football penalty.

It is known a device for monitoring a football penalty, containing a mh, having a touch time sensor associated with a first radio transmitter, a first radio receiver, an indicator interconnected by a second radio transmitter and a contact sensor placed in the goalie’s shoes, the second radio receiver, the first and second triggers, key, and the output of the first radio is connected to the S-input of the first trigger, the inverse output of which is connected to the D-input of the second trigger, the C-input of which is connected to the output of the second radio receiver, and the output of the second trigger It is connected to an indicator, wherein the R-inputs of the first and second flip-flops are connected to the key.

A disadvantage of the known device is the possibility of a situation where a violation by the goalkeeper of the rules when making an 11-meter shot, in which he must stand, without moving his feet before hitting the ball, does not lock.

Let the device be keyed in the initial state and the trainer gave a signal allowing the execution of an 11-meter kick. In this case, the D-input of the second trigger is set to 1 (FIG. 1, c), and at its output, O (FIG. 1, d). Let the goalkeeper move his feet immediately before the strike, i.e. violated the rules (Fig. 1, d), then the output of the second trigger will be set to 1 (Fig. 1, d) and the indicator will light up. Let the player hit the ball after the end of the movement of the goalkeeper (fig. 1.6), then O will be set at the D input of the second trigger (fig. 1, c). If the goalkeeper after hitting the ball again moves the feet (Fig. 1, d), then at the exit of the second triO O

the mountain will be set to O (Fig. 1d) and the indicator will go out. At short intervals between movements of the goalkeeper and hitting the ball and due to the inertia of the person’s vision, the indicator will go unnoticed and the goalkeeper will not violate the rules by the goalkeeper during an 11-meter hit.

The purpose of the present invention is to improve the accuracy of the device by determining the goalkeeper’s violation of the rules when performing an 11-meter strike during any movement of his feet.

The goal is achieved by the fact that the device for controlling a football penalty additionally introduces a third trigger, the S input of which is connected to the output of the second radio receiver, the R input with a key, and the output with the C input of the second trigger.

The proposed device, by introducing a third trigger, allows the goalkeeper to break the rules when performing an 11-meter strike during any movements of his feet, i.e. The device differs from the well-known new property, which leads to a positive effect.

Figure 2 presents the functional diagram of the device; FIG. 3 shows timing diagrams when a penalty is taken without breaking the rules; figure 4 - timing charts when performing a penalty in violation of the rules by the goalkeeper.

The device for controlling a football penalty contains m 1 with a sensor 2, which is mounted into it, and has contact with the radio transmitter 3, a radio receiver 4, an indicator 5, a radio transmitter 6 connected to the sensor 7, placed in the shoes of the goalkeeper, the radio receiver 8, the first 9 and 10 second trigger, key 11 and third trigger 12. The output of the radio receiver 4 is associated with the S input of the trigger 9, the inverse output of which is with the D input of the trigger 10, the C input of which is with the output of trigger 12. The output of the receiver 8 connected to the S-output of the trigger 12, and the output of the trigger 10 - with the indicator Ator 5, the R-inputs of the flip-flops 9, 10 and 12 are connected to the key 11,.

The device works as follows.

After switching on the device and the goalkeeper’s readiness and the player performing the 11-meter strike, the trainer with the key 11 sets the device to the initial position (fig.Za. 4, a) and gives a signal allowing the execution of the 11-meter hit. This D-input of the trigger 10 is set to 1 fig.Z.

4, c), at the C-inlet - O (fig.Zd; 4, d). O its output is O (fig.Z.e; 4, e) Indicator B. i.e. the signal light goes out if it has been burning up to this point.

When performing an 11-meter strike

without violation of the rules by the goalkeeper, upon hitting player 1, the player triggers sensor 2, which triggers radio transmitter 3. At the output of radio receiver 4, a signal appears

0 (FIG. 3.6), which triggers the trigger 9 and sets O on the D input of the trigger 10 (FIG. 3, c). After hitting the ball 1, the goalkeeper can repeatedly move the soles of the feet, sensor 7, placed in the insoles of the shoe, the goalkeeper works, turns on the power supply circuit of the radio transmitter 6, which will start to work. At the output of the radio receiver 8, signals (Fig. 3, d) appear at the S input of the trigger 12. The first signal of the trigger 12 is tilted to 1, which is fed to the C input of the trigger 10 (Fig. 13e). In this case, the trigger 10 does not overturn, since at its D-input at that time is O (FIG. 3c) and the indicator 5 does not work.

5In case of a goalkeeper violation

when performing an 11-meter strike, i.e. moving his feet before the strike on the mc, a signal appears at the output of the radio receiver 8 (figure 4, d), which enters the S0 input of the trigger 12 and overturns it in 1 (figure 4, d), as a result the trigger 10 also tilts in 1 (Fig. 4, e), since there is 1 at its D-inlet (Fig. 4, c). The signal from the trigger output 10 is fed to the indicator 5,

5 which shows that the goalkeeper violated the rules when performing an 11-meter strike. When hit on ball 1 by a player making an 11-meter hit, a signal appears at the output of radio receiver 4

0 (Fig. 4, b), arriving at the S-input of the trigger 9 and tilting it into O (Fig. 4, c), but the trigger 10 is not overturning at the same time (Fig. 4, e). When the goalkeeper moves after hitting the player with a 115 meter kick, the signals arrive at the S-input of the trigger (Fig. 4, d), but the state of the flip-flops 12 and 10 also does not change (Fig. 4, d ; 4.e).

Thus, the proposed device for the control of a football penalty allows you to identify violations of the rules by the goalkeeper when making an 11-meter hit during any movements of his feet.
