Abstract

portable electronic detection device with radio, characterized by the use of a piezoelectric Foliensensors, laminated or unlaminated, in a protective vest or a piece of clothing for measuring a mechanical impulse by impact / kick.

Description

The The invention relates to a detection device with radio link within a protective vest or sportswear such as a special shirt, in the a large-area piezoelectric Foil sensor is introduced.

at Applying an enemy blow becomes the mechanical impulse directly through the piezoelectric film sensor in a shock-proportional, converted electrical voltage and to a downstream amplifier stage issued.

The analogue output signal of the amplifier is digitized by a microprocessor, scaled and over a Transmitter level to a receiver sent as an input stage another microprocessor system is working.

This Reception processor uses special software to set the hit situation in the for the respective sport is typical way and performs a necessary statistic. The presentation takes place on a display / screen.

• – Die Bewertung und Auswertung von Treffern in der jeweiligen Kampfsportart (Teakwondo, Karate, Boxen) wird überwiegend von Kampfrichtern am Mattenrand vorgenommen. Dies ist trotz aller Erfahrung zwangsweise subjektiv. Durch die Erfindung wird dies objektiviert.
• – Die wenigen technischen Systeme, die auf diesem Umfeld in Erprobung sind, erfassen den mechanischen Impuls des Schlagen indirekt, über andere Mittlermedien, wie z. B. die Kompression eines pneumatischen Röhrensystems.

The invention presented here differs fundamentally from the previously common practice in the following points:

• - The evaluation and evaluation of hits in the respective martial arts (teakwondo, karate, boxing) is made mainly by referees at the edge of the mat. This is for all experience necessarily compulsory. This is objectified by the invention.
• - The few technical systems that are being tested in this environment capture the mechanical impulse of beating indirectly, via other medium media, such as: B. the compression of a pneumatic tube system.

This As a result, such a tube system applies accordingly, and so only in armor can be used. Furthermore is subject to the subsequent conversion of the pneumatic signal change in many cases metrological errors, what the reproducibility of the Result difficult.

• – Darüber hinaus trägt das Sensormaterial der Folie nur Bruchteile eines Millimeters in einer Schutzweste oder einem Sportshirt auf und wiegt im Vergleich mit Pneumatiksystemen nur wenige Gramm.
• – Die Foliensensoren sind im Gegensatz zu den steifen, pneumatischen Röhrensystemen hochflexibel und können in nahezu jeder Form geshaped werden.
• – Das so gewonnene Trefferergebnis wird über eine hochfrequente Sendestrecke, abhängig von den Erfordernissen der Entfernung der jeweiligen Sportart z. B. über das 433 MHz-Band, das 868 MHz-Telemetrie-Band oder Blue-Tooth übertragen.
• – Die Verarbeitung der Daten erfolgt auf einer X86 Architektur mit spezifischer Software.
• – Die Energieversorgung diese mobilen Systems wird abhängig von den Erfordernissen der Zuverlässigkeit mit Nickel-Metall-Hydrid oder Lithium-Ionen- oder Lithiumpolymer-Akkus sicher gestellt.

The applied invention detects the mechanical impulse directly and converts it also directly into an evaluable electrical signal. This is much less buggy than other conversion methods.

• - In addition, the sensor material of the film bears only a fraction of a millimeter in a protective vest or sports shirt and weighs only a few grams compared to pneumatic systems.
• - The foil sensors are in contrast to the stiff pneumatic tube systems highly flexible and can be shaped in almost any shape.
• - The score obtained in this way is transmitted over a high-frequency transmission route, depending on the requirements of the distance of the respective sport z. Via the 433 MHz band, the 868 MHz telemetry band or Blue-Tooth.
• - The data is processed on an X86 architecture with specific software.
• The power supply of this mobile system is ensured, depending on the requirements of reliability, with nickel metal hydride or lithium ion or lithium polymer batteries.
