Inland ship load measuring method based on ultrasonic liquid level measuring technology

Abstract

The invention discloses an inland ship load measuring method based on the ultrasonic liquid level measuring technology. The method includes that an ultrasonic probe of an ultrasonic liquid level detection device fixed on the edge of a ship deck is adopted to measure a distance D between the ship deck and the water, a computer connected with the ultrasonic liquid level detection device is adopted to calculate draught depth S of a ship, S=H-D, and H is the height of the ship. The computer conducts conversion according to the draught depth S of the ship and 'ship load and water gauge comparison table' to obtain the ship load and display the load through a display screen of the computer. By means of the measuring method, automatic measurement of the inland ship load can be achieved, and ship load accuracy is greatly improved compared with that measured by a traditional visual measuring method. Specifically, the method has the advantages of being capable of automatically obtaining ship load, convenient to use due to the fact that the measured data can be used for remote transmission, capable of preventing effect of water wave on measuring accuracy, high in measuring accuracy, capable of conducting measurement when the ship moves and high in application value.

Description

technical field [0001] The invention relates to the field of supporting measuring equipment for ships, in particular to a method for measuring and calculating the load of inland river ships based on liquid level measuring technology. Background technique [0002] The problem of load measurement in the process of ship cargo loading and unloading has always been a major problem for both parties in the transaction. At this stage, the ship load measurement in the port still uses the method of visually measuring the depth of the ship's waterline and then calculating it - the water gauge weight measurement method, that is, through Referring to the "Ship Load and Water Gauge Comparison Table" and other relevant information of the ship, the corresponding relationship between the draft of the hull and the load is obtained to measure the weight of the cargo loaded and unloaded by the ship. This method is often subjective, has large visual errors, and is affected by factors such as wav...

Problems solved by technology

This method is often subjective, and the visual error is large, and it is affected by factors such as waves in the port, so the obtained draft value is not accurate
