Embodiment Construction
[0039] In order to further understand the content, characteristics, and efficacy of the present invention, it will be described in detail with reference to the accompanying drawings:
[0040] Append figure 1 As shown, a ship S type meter system based on a portable differential positioner, including a differential positioning instrument module 1, a laser radar ranging module 2, a transmission module 4, a control calculation module 3, and a display module 5.
[0041] The differential positioning instrument module 1 is used to obtain an elevation data of the six-sided water of the ship S, the elevation, based on the sea plane. The differential positioning instrument module 1 includes a differential reference station, six satellite differential positioning instrument 1-1, six inertial measuring units, and six microprocessors. The differential reference station is mounted at the terminal for improving satellite positioning accuracy. The six satellite differential positioning instrument...

The invention discloses a ship water gauge metering system and method based on a portable differential positioning instrument. The system comprises a differential positioning instrument module used for obtaining the elevation data of a six-surface draught position of a ship; a laser radar ranging module used for acquiring distance data between the sea surface and the laser radar ranging module; a control calculation module used for calculating the six-surface draught position of the ship according to the elevation data and the distance data between the sea surface and the laser radar ranging module, so that the real-time loading and unloading speed of the ship and the quantity of loaded and unloaded goods of the ship can be estimated; a transmission module used for transmitting the elevation data and the distance data between the sea surface and the laser radar ranging module to the control calculation module; and a display module used for displaying the six-surface draught condition of the ship, the real-time loading and unloading speed of the ship and the loaded and unloaded quantity of the ship. According to the invention, the safety problem of ship loading and unloading rollover caused by manual observation errors is avoided, the labor intensity is reduced, and the water gauge metering precision is improved.
Description
Technical field [0001] The present invention relates to engineering techniques, and more particularly to a shipwater meter measurement system and method based on a portable differential positioner. Background technique [0002] In large ship loading and unloading amount, in particular, the shipping community at home and abroad has been measured for loading and unloading volume. During the water-scale observation process, 2-3 staff members need to watch the boat, boat, and boats around the water. The observation accuracy of the scale is limited by the weather, sea condition, visibility, day night and observer experience. In the case of poor external conditions, for example, under the condition of nighttime, observation accuracy is difficult to control, and it is easy to controversial. [0003] The taste of the staff reviewed by the staff is required to fill in the paper, then check the form, and have been cumbersome to calculate the amount of ship's loading or unloading amount, us...
