Embodiment Construction

[0055] The structure and working principle of the present invention will be further explained below in conjunction with the drawings and specific embodiments:

[0056] A ship draught detection system, such as figure 1 As shown, it includes a shipborne detection device 1 and a remote management system. The remote management system includes a remote management shipborne system 21, a remote management shore center system 22, and a remote management shore management system 23. The remote management shipboard system 21 acquires the relevant detection data of the shipborne detection device 1 through the communication unit, and then the wireless remote transmission unit transmits the data to the remote management shore-end central system 22. The remote management shore-end management system 23 communicates with the remote management shore via the Internet. The end center system 22 performs network connection and completes data interaction.

[0057] The ship-borne inspection device 1 is s...

Abstract

The invention provides a ship draught detection method. The method includes the following steps of S1 obtaining the measurement frame data of water surface, side underwater part of a ship to be detected, and the riverbed; S2 obtaining the horizontal distance and height value of each wave beam corresponding detected point relative to a sonar source; S3 obtaining part of the measurement data groups of the side underwater part of the ship to be detected; S4 calculating the measurement data groups to obtain the draught measured value of the ship to be detected; and S5 performing data correction on the draught measured value obtained from S4 to obtain the draught value data of the ship to be detected in the measurement frame. Based on the ship draught detection technology of an underwater sonar sounding system, the ship draught detection method realizes active, digital and automatic ship draught detection, thereby effectively reducing the manpower and material requirements and improving the detection efficiency and precision. According to the invention, smooth channel is guaranteed, the situation of obstructing the navigation can be prevented, the normal and smooth operation of industrial and agricultural production is guaranteed, and reliable material guarantee is provided for economic development.

Description

Technical field [0001] The invention relates to the field of measurement, in particular to a method for detecting the draft of a ship. Background technique [0002] With the continuous increase in the shipping volume of the Yangtze River and other rivers, the development of ships is showing a trend of large-scale development, and the draft is getting deeper and deeper. Ship stranding accidents occur from time to time, which not only damages the waterway and seriously threatens the safety of shipping, but also affects the efficiency of navigation. There are many reasons for the ship stranding, the most serious of which is overdraft, that is, the actual loading draft of the ship exceeds the waterway maintenance depth announced by the waterway department. [0003] There are many reasons for the overdraft of ships, both objective and subjective reasons. Objectively, the water level of different channels in the upstream and downstream is different, and the maximum draught of navigable...
