Embodiment Construction

[0027] The invention utilizes the principle of radar distance measurement to measure and calculate the distance between the ship and the navigation mark through a single-chip computer. When the distance between the ship and the navigation mark is less than the warning value of each level, the early warning system sends an alarm and can monitor in real time through the camera. At the same time, the collected alarm data and collected image information are centrally transmitted, and the real-time data is sent back to the command center of the navigation mark through the wireless network as evidence to determine the ship in trouble. The invention can warn the ship to prevent the collision with the navigation mark to a certain extent, and can do corresponding image collection work on the scene where the collision occurs, so as to facilitate the management of the navigation mark at sea by the navigation mark bureau.

[0028] Such as figure 1 and figure 2 The shown navigation mark ...

Abstract

The invention discloses an anti-collision radar device of a navigation mark, which comprises a lamp, a global positioning system (GPS) positioning meter and an electrical strain monitoring device. The anti-collision radar device of the navigation mark is characterized by further comprising a radar detection device, a camera, a radar signal processor and a wireless data transceiving device. Radar signals sent back by the radar signal processor is judged and processed by control of a single chip microcomputer; when a ship is at a primary early-warning distance, a primary early warning is carried out; when the ship is at a medium-term warning distance, the camera is started to begin to take photos of a dangerous ship and obtain evidences, and early warning is carried out once again simultaneously; and when the radar detection device detects the fact that a collision distance between the ship and the navigation mark is reached, the camera continuously takes photos of the dangerous ship until the dangerous ship is far away from a warning area. The anti-collision radar device has the advantages that the size of installed equipment is small, and the influence on the structural shape and floating conditions of the navigation mark is small. Besides, the anti-collision radar device is installed on the basis of an original navigation mark, is convenient and concise, saves fund, and is suitable for wide popularization in the field of the navigation marks.

Description

technical field [0001] The invention relates to a navigation mark anti-collision radar device. Background technique [0002] At present, most of the water buoys only have the function of positioning and indicating the channel, without other special preventive functions. When ships are sailing at sea, they often collide with the buoy due to the negligence of the on-duty officer or the poor maneuverability of the ship, resulting in damaged. Corresponding departments could not get the news about the damaged navigation mark in time, not only lost the navigation mark, could not catch the ship involved in the accident, but also caused a major threat to navigation safety. Therefore, it is very necessary to seek a good method to prevent marine ships from colliding with navigation marks. Nowadays, radar technology, camera technology and wireless network technology have all been greatly improved. The research of millimeter-wave radar is also close to maturity. It can detect ships at...
