Embodiment 1
[0065] Such as Figure 1-2 As shown, this embodiment relates to an intelligent lifesaving system based on GPS cruising and attitude calculation, including a lifebuoy 1, a plurality of mechanical arms 2 arranged on the lifebuoy 1, and a main control module.
[0066] Wherein, each mechanical arm 2 is provided with a gyroscope module electrically connected to the main control module, which is used to collect water ripple data and analyze the amplitude and frequency of water ripple in real time.
[0067] The gyroscope module is electrically connected to an attitude calculation module, and the attitude calculation module is electrically connected to the main control module to obtain the pitch angle and roll angle of the gyroscope module, and obtain the position of the vibration source through a wave detection and positioning algorithm.
[0068] The life buoy 1 is provided with a GPS module electrically connected to the main control module, and the main control module controls the l...
Embodiment 2
[0085] see Figure 1-3 As shown, a control method of an intelligent lifesaving system based on GPS cruise and attitude calculation includes the following steps:
[0086] A1. Calibrate all gyroscope modules and place the entire intelligent lifesaving system in designated waters;
[0087] A2, the main control module analyzes whether the water ripple data collected by the gyroscope module exceeds the threshold, if not, enter step A3, otherwise, enter step A4;
[0088]A3. Enter the cruising mode, the main control module controls the motor to cruise within the specified water area along the preset cruising route through the cruising algorithm according to the given speed, and return to step A2;
[0089] A4. Entering the search and rescue mode, the attitude calculation module obtains the pitch angle and roll angle of the gyroscope module, and obtains the position of the vibration source through the fluctuation detection and positioning algorithm;
[0090] A5. The difference betwee...

Abstract
The invention discloses an intelligent lifesaving system based on GPS cruising and attitude resolving. The intelligent lifesaving system comprises a life buoy, a plurality of mechanical arms arranged on the life buoy and a main control module, and a gyroscope module is arranged in each mechanical arm and used for collecting water ripple data; the gyroscope module is electrically connected with an attitude resolving module, is electrically connected with the main control module and is used for acquiring data of the gyroscope module and acquiring the position of a vibration source through a fluctuation detection positioning algorithm; a GPS module is arranged on the life buoy, and the main control module controls the life buoy to move along a preset cruise route or a search and rescue route through the GPS module and a cruise algorithm; and a plurality of motors are arranged on the life buoy and are used for driving the life buoy to move. According to the intelligent lifesaving system, the mechanical arm, the main control module, the gyroscope module, the attitude resolving module, the GPS module and the motor are additionally arranged on a traditional life buoy, the traditional life buoy is upgraded into the intelligent life buoy with low cost, cruising and search and rescue can be conducted on a designated water area, and the rescue efficiency is high.
Description
technical field [0001] The invention relates to the field of lifesaving devices, in particular to an intelligent lifesaving system and control method based on GPS cruise and attitude calculation. Background technique [0002] Most of the traditional intelligent lifesaving devices are designed to be worn on the body of the swimmer when entering the water. When in distress, the intelligent anti-drowning device can detect and activate the alarm system, pop up the airbag and other floating devices, and issue the designed sound and light alarm. Such products have improved the survival rate of a type of drowning incidents, but for accidental drowning incidents, they still cannot be solved. [0003] The remote-controlled intelligent lifebuoy developed subsequently is equipped with a high-speed underwater propeller, and the operator can use the remote control on the shore to make the intelligent lifebuoy quickly approach the person who fell into the water. This design not only sol...
