Problems solved by technology
In the existing back-sweep draft detection system, stainless steel brackets are used to fix the ultrasonic sensor array. This installation method not only consumes a lot of materials, is heavy, and is not convenient for installation and maintenance, but also has a small span, which can only realize short The draft measurement is carried out for navigable ships within the distance, but it is impossible to carry out draft measurement for ships within a large channel of about 100 meters
In addition, with the passage of time and changes in water flow velocity, water level, and water pressure in different seasons, the deflection of the stainless steel bracket due to force bending is also increasing, which will bring large system errors and affect the measurement accuracy and accuracy of data. sex

The invention provides a pitching scanning type ship draught detection system and method based on a flexible framework support. The system comprises a fixing module, an ultrasonic sensor array module,a water pressure sensor module, a floating body compensation module, a tilt angle monitoring module and a data processing module. The method includes the following steps that the fixing module is established; the ultrasonic sensor array module is established; the water pressure sensor module is established; the floating body compensation module is established; the tilt angle monitoring module isestablished; and the data processing module conducts acquisition and calculation. An ultrasonic sensor array is installed on a mooring rope with the strong flexibility, compared with a stainless steelsupport, the system is few in consumed material, light in weight, capable of achieving automatic lifting, convenient to install and overhaul and capable of striding across a whole hectometer channeland achieving draught measurement of a navigation ship within a large range. The deflection of the mooring rope with a flexible framework is easy to adjust, a system error is reduced and compensated,and measurement accuracy is improved.
Description
technical field [0001] The present invention relates to the technical field of back-sweep type draft detection of a ship under test, in particular, to a system and method for back-sweep type ship draft detection based on a flexible structure support. Background technique [0002] In recent years, with the improvement of navigation technology, my country's shipping volume has been increasing every year, and its cargo transportation has become more and more important in the development of my country's national economy. Therefore, it is very important to ensure the smoothness and safety of inland river transportation in our country. In the existing back-sweep draft detection system, stainless steel brackets are used to fix the ultrasonic sensor array. This installation method not only consumes a lot of materials, is heavy, and is not convenient for installation and maintenance, but also has a small span, which can only realize short The draft measurement is carried out for nav...
