Problems solved by technology

However, due to multi-channel interference, the reflected wave and the non-reflected direct wave are aliased or the reflected wave reaches the receiving signal terminal through other paths, which affects the measurement accuracy and accuracy of the system, and the final calculated draft of the ship is far from the actual draft. depth

Embodiment Construction

[0034] The present invention will be further explained below in conjunction with the drawings:

[0035] Such as figure 1 As shown, a side-mounted ship draught detection system includes a high-frequency absorbing module 4, an ultrasonic transmitting module 2, an ultrasonic receiving module 3, a pressure sensing module 5, an automatic lifting module 1, a synchronous time-sharing control module 9, and data processing Module 10 and display alarm module 11;

[0036] The high-frequency absorbing module 4 is composed of a high-frequency absorbing material and a fixed plate. The high-frequency absorbing material is pasted on the surface of the fixed plate and installed on both sides of the channel to absorb and spread to the surface of the high-frequency absorbing material. In order to prevent the reflected ultrasonic waves from aliasing with the unreflected direct waves 7 or reaching the receiving end through multiple reflections, the purpose of eliminating multi-path interference is fin...

Abstract

The invention discloses a side-mounted draft detection system and an operating method thereof. The side-mounted draft detection system comprises high-frequency absorption modules, an ultrasonic transmitting module, an ultrasonic receiving module, pressure sensing modules, an auto-lift module, a synchronous time division control module, a data processing module and an alarm module. The high-frequency absorption modules comprise high-frequency absorbing material and fixing plates, are mounted on two sides of a navigation channel and are used for absorbing ultrasonic wave propagating to the high-frequency absorbing material, multi-path interference is eliminated, data processing is more vivid and simpler, and measuring precision is greatly improved. The synchronous time division control module controls the ultrasonic transmitting module to transmit the ultrasonic wave sequentially and cyclically at equal intervals; the ultrasonic receiving module transits effective range and strength information of received direct wave to the data processing module; draft of a ship is calculated finally; the auto-lift module can adjust underwater depths of the fixing plates provided with ultrasonic sensors, on two sides of the navigation channel, according to level change information, thereby adapting to water level changes and facilitating maintenance.

Description

Technical field [0001] The invention is applied to the fields of ship draft detection and ship safety detection, and particularly relates to a side-mounted draft detection system and a working method thereof. Background technique [0002] The leading role of shipping in the development of the national economy has become increasingly significant, and the volume of shipping has also continued to increase, resulting in a substantial increase in the density of ships in the channel. Ship draught detection is of great significance for ensuring the safety of navigable ships. The existing side-mounted draft detection system uses an ultrasonic transmitter sensor and an ultrasonic receiver sensor to calculate the ship's draft according to the effective range and intensity of the received ultrasonic signal. However, due to multi-way interference, the reflected wave and the non-reflected direct wave are aliased or the reflected wave reaches the receiving signal end through other paths, whic...
