Embodiment Construction

[0041] See Figure 1, Figure 4, and Figure 5. The ship tonnage intelligent measurement system of this embodiment includes two infrared sensors 1 arranged on the bank walls at both ends of the channel measurement section; Nano array 2; one image capturing device 4 arranged above and on the side of the channel measurement section; a signal used to control sonar scanning and send the received signal output by the infrared sensor and the sonar signal to the computer 5 Processing circuit 3; the image information collected by the image capturing device 4 is directly sent to the computer 5.

[0042] See Figure 4 and Figure 5. The distance between the two infrared sensors is h. The infrared sensor monitors the ship in the channel, and the two infrared sensors at each end are both set to (1, 0), which is valid only when the channel is measured. When the infrared sensor on the outer side of one end first detects the ship, the sonar arrays arranged on both sides of the channel and the image c...

Abstract

The present invention relates to an intelligent measuring system of ship for tonnage a measuring method. The measuring system includes: at least two infrared sensors positioned on the two sides of quaywall of the channel section to be measured; a sonar array provided on the two sides of riverbed wall of the channel section to be measured; two image shooting devices positioned on the upper side and the lateral side of the channel section to be measured; a signal processing circuit for controlling the sonar scanning and for transmitting the signals output by the infrared sensor and the sonar signals to the computer; the image information collected by the image shooting devices is transmitted to the computer directly. The whole tonnage, the net tonnage and real loading tonnage of the ship can be measured accurately in time. The method in the present invention has the characteristics of high degree of automation, accurate measuring and high efficiency etc. comparing the method of person observing and coarse estimate. Thus, the automation operation in the ship department can be realized and the accuracy of the statistic data, the efficiency and the intelligent level of the shipping trade are all improved.

Description

Technical field [0001] The invention relates to a measuring system and a measuring method, in particular to an intelligent measuring system and a measuring method of ship tonnage. Background technique [0002] Among various transportation channels, inland waterway shipping has the advantages of low freight rate, large volume, low energy consumption, and low investment. Accurate statistics on the tonnage of inland waterway ships will provide relevant departments with a complete and accurate basis for decision-making. At present, the gross tonnage and net tonnage of ships are obtained by the specialized ship inspection department in accordance with relevant measurement regulations, using manual measurement methods, and the error is relatively large. The actual carrying tonnage is mainly estimated by manual observation, that is, the actual carrying tonnage of the ship is estimated based on the gross tonnage, load line and actual draught of the ship certificate. This statistical meth...
