alarm system

Abstract

The invention relates to an offshore undercurrent alarming system, which comprises an undercurrent region detection device, a human body identification device, a main control device, a voice alarming device and a display device. The undercurrent region detection device is used to detect the position of the offshore undercurrent and outputs the region number of the oceanic region where the undercurrent is located as a first number. The human body identification device is used to perform human body identification from an offshore oceanic image based on the image analyzing mode and outputs the region number of the oceanic region where the human body is located as a second number. The main control device is connected respectively with the undercurrent region detection device and the human body identification device and is used to output an undercurrent alarming signal when the first number and the second number repeat. With the alarming system of the invention, it is possible to instantly make alarming operations to the offshore undercurrent region conditions where a human body enters so as to effective prevent the occurrence of oceanic accidents.

Description

technical field [0001] The invention relates to the field of maritime monitoring, in particular to an alarm system. Background technique [0002] The offshore area is the main place for people to go to the beach. Especially for the beach, swimming in the offshore, enjoying the impact of the waves on the body, and feeling the vastness of nature is an unforgettable sport. [0003] However, when playing in the offshore area, if there is an undercurrent and the human body is in the position of the undercurrent, the undercurrent can easily lead people into the deep sea area and fall into a state of helplessness. The speed of the undercurrent is so high that it is impossible to swim sideways. If tourists are experienced and able to keep calm, they can swim with the water to the back of Liutou, and then swim to both sides. Swimming back with the help of the waves is also a way. If you are already in an undercurrent, first of all, don't think about swimming back to the shore. What ...

Problems solved by technology

[0004] In fact, there are very few tourists with such rich experience. Most of them are frightened by unexpected situations and swim desperately to the shore. However, because the speed in the undercurrent is faster than people's swimming speed, it is not only ineffective, but also wastes a lot of energy. In the existing technology, there is no alarm mechanism for undercurrents around the offshore area
