Measuring apparatus and method of inland vessel load based on pressure measuring technology

Abstract

The invention relates to a measuring apparatus and method of inland vessel load based on the pressure measuring technology. The measuring apparatus comprises a pressure measuring device and a load converting device. The pressure measuring device comprises a shell, a pressure sensor, a temperature sensor, an analog-digital converter and a waterproof data cable, the shell is a cylindrical cavity, and the pressure sensor is made of a drop-in pressure probe. The load converting device comprises a single-chip microcomputer chip, a data-storage chip, a display screen, a GPS and Beidou satellite dual-mode receiver and a power circuit. A GPS and Beidou satellite dual-mode circuit is externally connected, vessle's navigation speed is measured in real time by the GPS or the big dipper dual-mode receiver. Pressure data, temperature data, navigation speed data and draft survey data are synthesized and calculated by software of an upper computer to obtain vessel load data. Vessel loading capacity auto-measuring is achieved, and vessel loading capacity is automatically obtained. The measuring data can be applied to remote transmission. The measuring apparatus is convenient to use. Measuring accuracy is not affected by water temperature changes. Measuring is available even when the ship sails. The measuring apparatus and method of inland vessel loading based on pressure measuring technology has high application value.

Description

technical field [0001] The invention relates to the field of supporting measuring equipment for ships, in particular to a load measuring device and method for inland water ships based on pressure measurement technology. Background technique [0002] At present, the problem of load measurement in the process of cargo loading and unloading of waterway transport ships has always been a major problem for both parties to the transaction. At present, the measurement method of inland water ship load is generally to use manual observation of the draft of the ship, and then check the "water gauge and load capacity" according to the draft value. The measurement accuracy of this method mainly depends on the accuracy of the water gauge reading on the hull. This method is often subjective, has large visual errors, and is affected by factors such as waves in the port. is not an exact draft value. [0003] With the development of automation technology, the existing measurement method of m...

[0002] At present, the problem of load measurement in the process of cargo loading and unloading of waterway transport ships has always been a major problem for both parties to the transaction. At present, the measurement method of inland water ship load is generally to use manual observation of the draft of the ship, and then check the "water gauge and load capacity" according to the draft value. The measurement accuracy of this method mainly depends on the accuracy of the water gauge reading on the hull. This method is often subjective, has large visual errors, and is affected by factors such as waves in the port. is not an exact draft value

[0003] With the development of automation technology, the existing measurement method of manual observation of ship draft can be completely changed by means of sensors and automatic control technology. However, there is no literature report on this kind of method, and no practical application has been seen. How to solve this problem has become an issue in this field. Topics to be researched and solved by technicians
