Marine draft detection system

Abstract

The application discloses a marine draft detection system, comprising an external power source and a single-beam detector. The single-beam detector includes a power circuit, a DSP (digital signal processing) circuit, a transmitting circuit, a receiving circuit and a transducer; the external power source is electrically connected with the power circuit so as to provide power of preset range for thepower circuit; the power circuit converts the power of preset range so as to provide power of corresponding values to the DSP circuit, the transmitting circuit, the receiving circuit and the transducer; the DSP circuit and the transducer are electrically connected with the transmitting circuit and the receiving circuit respectively; the DPS circuit is in serial port communication with an externalcommunication device. Measurement data acquired by the DSP circuit can be transmitted directly to the external communication device with no need for the single-beam detector to have a main board anda display screen; the structure of the system is simplified, and the system is imparted the advantages of low power consumption, wide range of power input, good precision of measured values, small size, good operational convenience and the like.

Description

technical field [0001] The invention belongs to the technical field of ship draft detection and relates to a ship draft detection system. Background technique [0002] With the increase in the number and density of river shipping ships, ship accidents pose an increasingly serious threat to shipping safety, the most serious of which is the problem of ship overdraft. Driven by interests, some ship merchants ignore the country's shipping overload ban and adopt Falsely reporting the tonnage and draft information of ships, even manufacturing false waterlines, and passing through shallow water areas at night to evade the inspection of maritime law enforcement agencies, resulting in successive overload and grounding accidents. These accidents not only caused direct economic losses for stranded ships, but also affected The normal passage of rivers and waterways. Therefore, there is an urgent need for a solution that can quickly and accurately detect the draft of a ship. [0003] A...

Problems solved by technology

The single-beam echo sounder mainly measures the water depth by transmitting signals from the transducer to the bottom of the water. Therefore, the traditional single-beam echo sounder has a relatively bulky volume, high power consumption of the whole machine, and many false values ​​when hitting the water surface. , there is no networking function, and there are many parameters to be adjusted manually.
