The purpose of this utility model provides and a kind ofly can monitor, calculate spring to trampolinist's state

Bed motion person's the net-fault time and the trampoline synchronizing testing system of duration of passage.

The purpose of this utility model is achieved through the following technical solutions:

This practicality comprises sensor, connecting line and the processor of mutual electrical connection, and described sensor is a vibrating sensor, and described vibrating sensor places the edge of trampoline, and be close to net below.

Described connecting line is signal connecting line and USB connecting line, and described signal connecting line is electrically connected vibrating sensor with processor, and described USB connecting line is electrically connected processor with computer.

Described processor comprises analog amplify circuit, analogue filter circuit, A/D change-over circuit, crystal oscillator, single-chip microcomputer and the usb interface module of mutual electrical connection.

Described vibrating sensor is measured the vibration information of trampoline online in real time, handles through processor, judges athletic motion state on the trampoline according to the size of vibration signal, and then calculates athletic net-fault time and duration of passage.

Described converter is a power supply changeover device, and power supply changeover device comprises transformer, rectifier bridge, voltage-stablizer and the wave filter of mutual electrical connection.

As a further improvement of existing technologies, the range 〉=1g of vibrating sensor; The model of single-chip microcomputer is C8051F320 in the processor.

With respect to prior art, the beneficial effects of the utility model are:

One, the utility model adopts the state of the net on the vibrating sensor real time monitoring trampoline, handle through processor, export computer in real time to, computer is judged athletic state according to the state of net, and then calculate athletic net-fault time and duration of passage, and to use eyes to judge athletic state, use stopwatch to come compare computing time with present coach, the data of the utility model record are more accurate, objective;

Its two, the utility model comprises a vibrating sensor, a signal processor and two connecting lines, the utility model is simple, easy for installation, and does not destroy original facility, and the structure and the performance of trampoline do not exerted an influence;

Its three, the vibrating sensor in the utility model is installed in the trampoline edge, be close to net below; above the net is neonychium; the sportsman cannot see vibrating sensor on trampoline, to the not influence of athletic psychology, and also not influence of the performance of action during to training athlete or match.
