Inland port ship load measuring system and method

Abstract

The invention relates to an inland port ship load measuring system and a method for applying the measuring system. The inland port ship load measuring system comprises a signal sending device, a signal receiving device, a signal processing unit and a signal transmitting device. The signal sending device comprises a sending probe. The signal receiving device comprises a receiving panel and a plurality of receiving probes, wherein the receiving probes are vertically arranged on the receiving panel at equal intervals along a straight line. The signal receiving device is used for receiving signals sent by the signal sending device so as to produce signal hopping. The signal processing unit is used for inputting empty-ship waterlines and corresponding ship models, it is determined the sent signals are received by the corresponding receiving probes on the receiving panel according to the signal hopping, and changes of drafts are determined by the receiving probes producing the signal hopping. The signal transmitting device is used for sending data of the signal processing unit to law-enforcing departments and supervisory institutions of the port office and related workers of all ship locks. Through the inland port ship load measuring system and the method, workers related to port administrative affairs can obtain the weight of the cargo of a cargo ship in real time.

Description

technical field [0001] The invention relates to the field of ship equipment, in particular to a system and method for measuring the load of an inland port ship. Background technique [0002] Cargo ships have to pass through ship locks in the process of driving in the inland waterway, and each time they pass through a ship lock, they have to pay according to the actual cargo tonnage of the ship. An important reference for the staff of the Port Authority to verify the actual cargo load of the cargo ship is the cargo list issued by the port staff. Driven by various interests, the port staff and the ship driver jointly provided the port staff with a false bill of goods in order to miss the fee for passing through the gate. Most of the cargo ships risk overloading because of this, which not only brings huge potential safety hazards but also leads to a large loss of national property. At present, the method for domestic inland waterway port staff to judge whether the ship has fa...

Problems solved by technology

However, the underwater environment is relatively complicated, and the water inlet capillary and float used in the device in this method are easily blocked by sundries (especially the cargo scattered during the loading process of the ship), so that the height of the float is lower than the water surface height, resulting in relatively high large measurement error

Moreover, since the ultrasonic transmitting and receiving devices are installed in the anti-shock slope pipe, the reflection of the inner wall of the pipe will also interfere with the transmission of ultrasonic waves in the pipe, thereby affecting the final measurement results.
