Narrow waterway channel passage monitoring device

Abstract

The invention provides a narrow waterway channel passage monitoring device, which comprises an upper floating plate and a lower floating body. The bottom center of the lower floating body is providedwith a distance measuring sensor; and the lower floating body is internally provided with an adjusting chamber. The upper surface of the upper floating plate is provided with a protection cover in a regular quadrangular frustum structure. The protection cover is internally provided with a PLC controller and an energy storage battery. The top portion of the protection cover is provided with a navigation channel indicating lamp and an acousto-optic alarm. The upper floating plate is also provided with a solar cell panel, a wind speed sensor, a temperature sensor and a humidity sensor. The PLC controller is connected with an axial flow fan, a water suction pump, a first valve, a second valve, the navigation channel indicating lamp, the acousto-optic alarm, the wind speed sensor, the temperature sensor and the humidity sensor. The device can monitor real-time information of the waterway channel and can carry out connection and dialogue with ships entering the navigation channel range, is reasonable in structure, simple to install, simple to install and low in cost, is suitable for narrow channel projects and helps popularization and application.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device for passage of a narrow waterway. Background technique [0002] In recent years, my country's inland shipping has developed rapidly. At present, an inland shipping system with the Yangtze River, Pearl River, Heilongjiang, Beijing-Hangzhou Canal and other water systems as the backbone has been initially formed, and there are many inland ships. At present, there are about 180,000 inland ships over 100 gross tons. Ships and above have greatly promoted economic and social development. However, due to the wide distribution and complexity of waterways and the different sizes of ships passing through, the supervision of inland waterway ships has become increasingly severe. At present, the main means for maritime affairs to identify ships entering and leaving the jurisdiction include on-site patrol by maritime personnel, manual monitoring of bayonet video, etc. [0003] Patent ...

AI Technical Summary

Problems solved by technology

The sound field signal of the ship in the river channel is converted into an optical signal after being received by the underwater acoustic sensor unit, and then transmitted to the shore through the communication optical cable for photoelectric conversion into an electrical signal, and then sent to the computer or signal processing control board, and the output signal is calculated by the signal processing module. Real-time monitoring of indicators such as flow, position, heading, and speed of inland river vessels. The present invention provides an active, widely applicable and strong anti-interference ability automatic monitoring system for inland rivers. The system is not limited by weather conditions. , which can monitor inland waterways in real time around the clock; this system cannot realize the overall management of operating ships, and has limitations in actual use
