Device and method for measuring ship loading by draft sensor

Abstract

The invention relates to a device for measuring ship loading by a draft sensor. The device for measuring the ship loading by the draft sensor comprises four loading instrument sensors, wherein the output of the loading instrument sensors is connected with an AD (analog-digital) conversion module; the output of the AD conversion module is connected with a magnetic isolation circuit; the magnetic isolation circuit is connected with an ARM (Advanced RISC Machines) mainboard; and the ARM mainboard is connected with an audible and visual alarm and a printer. The method for the device comprises the following steps of: initializing a system; setting a parameter; collecting a sensor signal; reading data; calculating the corresponding ship draft depth; searching a table to obtain a loading numerical value of the corresponding depth; carrying out inclination correction on the loading numerical value; giving an overloading alarm; carrying out screen display and printing output. The device disclosed by the invention has the advantages of reasonable design structure and convenience in installation, the ship body draft can be monitored in real time by a pressure sensor and displayed after calculation, and an effective reference basis is provided for the ship loading situation.

Description

technical field [0001] The invention belongs to the technical field of ship loading measurement, in particular to a device and method for measuring ship loading by using a draft sensor. Background technique [0002] The actual draft inspection of the traditional ship mainly adopts the water gauge of the ship and the actual measurement in the cabin, and the error is relatively large. In particular, some ships do not have water gauges, or the water gauges are inaccurate (deliberately depicting small water), and the actual draft is greater than the draft indicated by the water gauge. Some ships are also equipped with bottom guards at the bottom, and the part of the bottom guards that protrude from the hull cannot be observed at all on site. As a result, it is difficult for the waterway administrative personnel to truly grasp the actual draft of the ship, and it is impossible to obtain strong evidence to prove that the ship is an "over-draft" ship. caused losses.

[0002] The actual draft inspection of a traditional ship mainly uses the water gauge of the ship and the actual measurement in the cabin, and the error is relatively large

In particular, some ships do not have a water gauge, or the water gauge is inaccurate (deliberately depicting small water), and the actual draft is greater than the draft displayed by the water gauge, etc.

There are also some ships with bottom guards installed at the bottom, and the part of the bottom guard that protrudes from the hull cannot be observed on site.

As a result, it is difficult for the waterway administrative personnel to truly grasp the actual draft of the ship, and it is impossible to obtain strong evidence to prove that the ship is an "over-draft" ship. loss caused

[0003] At present, the manual method of visually measuring the scale line of the hull draft will lead to inaccurate draft data, large deviation of visually obtained draft data, and large deviation between the ship's cargo load and the actual load. Therefore, a new device and method for measuring ship load has been developed. very necessary
