Problems solved by technology
The former has obvious flaws. Ship owners will try to destroy or affect the working status of the sensors installed on their respective ships in order to make profits from overloading, thus making the accuracy of the measurement data unreliable; while the latter only rely on video analysis to measure, it is difficult Achieve high measurement accuracy, and the measurement results are easily affected by factors such as weather conditions and light conditions

Embodiment Construction
[0039] Such as figure 1 and figure 2 Shown is a block diagram of the working principle of the system of the present invention and a schematic diagram of the installation structure.
[0040] 1) Ship monitoring part
[0041]The ship monitoring part is the frontier part of the channel ship overload and overdraft monitoring system, and is the "eye" of the entire system, including the AIS signal receiver, the distance measuring sensor 5 installed directly under the bridge 1, and at least two video cameras on both sides of the bridge 1 The linkage device 3 and the sensor 4 with a cloud platform, and the ranging buoys 6 on both sides of the channel. The at least two video linkage devices 3 are respectively fixed on both sides of the bridge, forming an included angle of 0°-90° with the water surface, and are respectively used to monitor ships heading up and down the water. Under the bridge, more than two (depending on the channel width to be monitored) sensors 4 with a cloud platf...

The invention belongs to the category of automatic measurement technology, and in particular relates to an automatic draught monitoring system and method for river vessels. According to the automatic draught monitoring system and method, a mechanical millimeter-wave radar (laser) sensor with a high-precision holder serves as core equipment for monitoring the draught of the vessels; and a sensor system is distributed below a bridge for monitoring the passing vessels in a maneuvering way. The sensor is used for performing profile survey and quickly acquiring profile image data of each vessel body, so that the distance from the current vessel to the bridge and the draught state of the vessel can be measured through software, the actual draught depth of the vessel can be calculated, and the actual draught depth of the vessel is compared with the checked draught depth of the vessel to determine whether the vessel is overloaded. The automatic draught monitoring system can be distributed below the bridge of a shipping lane, has advantages of high measurement precision, flexibility in control, high real-time performance, and fast speed, etc., can be widely applied to monitoring the draught in various shipping lanes, and has very important realistic meanings to strict monitoring on the draught depth of the vessels in the shipping lane.
Description
technical field [0001] The invention belongs to the category of automatic measurement technology, and in particular relates to an automatic monitoring system and method for inland river vessel draft based on a millimeter-wave radar (laser) sensor with a high-precision pan-tilt and video analysis. Background technique [0002] The actual freeboard height of a ship generally refers to the vertical distance measured from the waterline along the side to the edge of the upper continuous deck (freeboard deck); the actual ship draft generally refers to the vertical distance measured from the waterline along the side to the lowest point of the bottom of the ship the vertical distance. In recent years, the phenomenon of "overloading" and "overdraft" on the main channel of the Yangtze River has become more serious, and the situation is not optimistic. [0003] The "overloading" of ships directly threatens the safety of water traffic, and has become the "number one killer" of water tr...
