Abstract

The invention discloses a stress detection and early warning system of a ship tow. The system comprises a host provided with a display device and an alarm device; a main control board is arranged inside the host; and a single-chip microcomputer, an AD converter and a signal transmission device are arranged on the main control board. In addition, the system also includes a force sensitive sensor installed at a ship tow; the force sensitive sensor is connected with the single-chip microcomputer by the AD signal converter and the signal amplifier; the single-chip microcomputer is connected with the alarm device, the display device, and a database terminal; and the single-chip microcomputer is also connected with a remote monitoring terminal by the signal transmission device. According to theinvention, the system has advantages of simple structure and principle and high intelligent degree and has functions of real-time tow stress monitoring and advanced early warning; and security of therope towing and mooring work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ship cable stress detection, in particular to a ship cable stress detection and early warning system. Background technique [0002] There is no doubt about the importance of marine cables as working tools for mooring, towing, fixing, etc. in marine operations. If the ship breaks the cable accident, it may not only cause the accident of touching the wharf or surrounding ships due to the uncontrolled drift of the ship, but may also cause casualties, resulting in huge economic losses and social impact. The essential reason is that the external force on the cable is greater than the allowable strength of the cable. It is often manifested in the following aspects: 1. The friction between the cable and the side of the ship is inevitable, and the friction causes the cable to break, thereby reducing the strength of the cable; 2. When the ship is berthing, the force on multiple cables is uneven, and the external ...
