Problems solved by technology

[0002] For a long time, the automation level of daily operation of ship locks in my country has been low, and the measurement of the draft of ships passing the locks is mostly done by simple manual methods. Due to the uneven draft of the hull caused by uneven cargo loading, the accuracy of manual measurement is low, and the draft cannot be effectively controlled. Ultra-deep ships pass the lock, resulting in damage to the lock sill and apron, and even endangering the safety of the ship, causing unnecessary loss of life and property
At the same time, the ship owner's own modification of the ship caused the actual draft of the ship to exceed the design draft, which aggravated the harmfulness of this problem

Abstract

The invention relates to a method and a device used for controlling draught over-depth and ship lockage, and belongs to the technical field of automatic ship lockage control. The control method of the invention comprises the following steps of: detecting whether a ship enters a detection area by using an infrared sensor; when the ship enters the detection area, detecting whether the draught over-depth of a lockage ship exceeds a predetermined limit by using an ultrasonic sensor; and giving an alarm for the ship of which the draught over-depth exceeds the predetermined limit by using a sound and light alarm device so as to prevent the ship from passing. The device of the invention comprises an infrared sensor module, an ultrasonic detection module, a sound and light alarm device, a video acquisition device, a control display module, a video recording device, a signal analyzing and processing module, and a power supply module. Compared with original manual ship draught over-depth measurement, the method and the device can effectively avoid the problems of high subjectivity and the like in the manual measurement, have the advantages of accurate measurement and high automation degree, improve the operation efficiency of a ship lock, protect facilities such as a lock sill, a protection-apron and the like of the ship lock, and prolong the service life of the ship lock.
