The buoy fixing device only needs to be capable of fixing and positioning the buoy, and the structure capable of realizing automatic floating of the positioning buoy after receiving the feedback signal of the vehicle water falling detection module is within the protection scope of the patent. If the buoy fixing device adopts an electromagnetic mechanism to attract the positioning buoy 100 to the vehicle body, the electromagnetic mechanism can be powered off after the vehicle falls into water, and thus the positioning buoy 100 can float upwards automatically.
When the vehicle falls into water, the vehicle falling-water detection module sends a signal to the buoy fixing device, and the buoy fixing device is unlocked to enable the positioning buoy to automatically float to the water surface; the positioning buoy realizes the position positioning of the positioning buoy through the GPS positioning module and sends the position of the positioning buoy and the rescue information to the outside through the wireless communication module. In order to realize accurate positioning, an ultrasonic signal transmitter is arranged on the vehicle body, an ultrasonic signal receiver is arranged on the positioning buoy, and the position information of the vehicle is transmitted to the ultrasonic receiver on the positioning buoy through the ultrasonic transmitter so as to obtain the distance between the vehicle and the positioning buoy and the position information.
As shown in fig. 5, when the GPS positioning module performs position positioning, the following method may be adopted: by measuring the propagation time of a ranging code signal transmitted by the GPS satellite 300 to a receiver of the GPS positioning module 103, the geometric distance between the GPS positioning module and the satellite 300 is calculated, and under the condition of simultaneously capturing the space coordinates of three or more satellites, the geometric distance parameters of three or more satellites and the GPS positioning module are substituted into an Euclidean coordinate distance equation set under the same rectangular coordinate, the space coordinate of the GPS positioning module is solved, and the position of the GPS positioning module is further determined.
The vehicle falling water escape positioning system directly detects the inclination angle of the vehicle falling into water through the inclination angle sensor, and selects the corresponding escape channel according to the inclination angle, so that people in the vehicle can escape quickly. Compared with the prior art, the multi-channel escape system has the advantages of higher reaction speed and stability and can achieve very good technical effect.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
