Description

Description

Technical name

Device for real-time information for athletes and coaches for simultaneous and location-independent display of sport-specific parameters.

State of the art

In the sport of rowing, systems are known that display sport-specific parameters alphanumerically in the rowing boat, but do not transmit them telemetrically. A disadvantage is the lack of information about the trainer. In general, data is stored on the water during training, depending on the sensors available, and then transferred to a PC on land and displayed. Recently, there have also been variants of display in real time on a PC, where the trainer, but not the rower, receives selected information. A disadvantage is that athletes and trainers only receive information about the movement execution after training. Another disadvantage is the high energy expenditure, which has to be covered in the form of relatively large and therefore heavy energy sources.

problem

The invention specified in claim 1 is based on the problem of developing a complex real-time information system that allows athletes and trainers, separated in space, to have free access to the entire amount of information resulting from the connected sensors, in particular the combined display of analog characteristic curves and alphanumeric characteristic values on a graphic display each and additionally for a review of the training, the mixture of characteristic curves and video image, which is implemented in the trainer display, parts of the system remain individually operable.

Solution

The problem is solved with the features stated in claim 1.

Beneficial effect

The invention ensures that sport-specific parameters, such as rowing force, rowing angle or acceleration, are qualitatively, simultaneously and regardless of location available to athletes, especially rowers, and coaches.

This device makes it possible to evaluate the quality of movement execution directly during training, to check the effects of a varied movement on its effectiveness and, together, the athlete and the trainer, to find the optimal movement execution for the individual athlete more quickly.

Description of the invention

The device according to the invention is explained in more detail using an embodiment shown as a block diagram in the drawing.

The device is used to assess the movement sequences of competitive athletes in rowing boats.

In the exemplary embodiment, the device 1 consists of a measurement value acquisition unit 2, an athlete display 3 and a trainer display 4. The measurement value acquisition unit 2 digitizes the electrical signals from various sensors 5 in the analog-digital converter 6. In a microprocessor 8 of the type 80C535, the data is compressed and standardized according to a program stored in the program memory ROM 7 and fed to the main memory RAM 9 and stored. The data is sent to the HF transmitter 10 and the microprocessor 13 of the athlete display 3 via the serial data line 11. The same information is therefore also available to the microprocessor 17 via the HF receiver 15 of the trainer display 4. The further, almost simultaneous processing of the data takes place according to the programs stored in the program memories ROM 12 and 16. The numbers to be displayed, such as the rudder application angle, or curves, such as the rudder force curve during the pull-through, are output on the LCD graphic displays 14 and 18. In addition, a BAS signal that complies with television standards is provided in the video image signal generation 19 for storage on a video recorder, which contains essential contents of the LCD graphic display 18.

However, the application of the invention is not limited to the embodiment. In fact, many problems of diagnosing sport-specific movement sequences can be solved by using the device according to the invention. Other water sports and sports where the trainer and athlete are geographically separated are particularly suitable.

The device can be modified to adapt to specific tasks. It is possible to operate parts of the device, such as just the measurement data acquisition unit or the measurement data acquisition unit and trainer display.
