Micro Wave Buoy

This type of buoy is a professional wave monitoring buoy that used to measure small waves. It is a special wave buoy which adapts to various short cycle and measurable wave height 2cm.

Working Principle

This wave buoy is composed of an accelerometer, a voltage frequency module, a radio etc.. With the wave motion of the wave, the output of the accelerometer is converted into a V/F, whick is transmitted back to the shore station in time.

Differences from common wave buoy

1. This buoy is used to simulate the communication mode, the acceleration of the accelerometer to get the acceleration, through the V/F transform, the voltage to the amount of frequency, and then transmit to the shore station through FM station.

2. After receiving the signal, the shore station experienced the analog signal and the waveform of the reduction of the F/V transform, and entered the A/D conversion of the single chip microcomputer to enter the data sampling program. The main advantage is that the sampling frequency can be very high (32Hz), and the wave of the lake should be sampled with a high sampling frequency.

The shore station receives all the data sent back by the buoy and automatically calculate the characteristic value of wave height in the PC receiving interface and the value displayed on the interface are respectively as follows: average wave height, maximum wave height, 1/10 wave height, 1/3 wave height, average period, the period of the biggest wave, 1/10 period, 1/3 period, wave number.
