In order to obtain accurate measurement results on flatness of the underwater object detection

an underwater tilt detecting system is used based on sensor technology

electronic technology

MCU technology

communication technology

computer programming technology

and so on.The results are automatically saved in form of data

and supported by 3D graphics display.The system is successfully applied in immersed tunnel engineering on Luntou—Bioisland—Universitycity in Guangzhou.Experimental results show that it has the characteristics of convenient measurement

high precision

simple operation

good stability.It plays a key role in detecting underwater support block of channels

tunnels and dams.
