Method and device for implementing wireless call for help

Abstract

The invention relates to a method and a device that can realize wireless distress-call for vehicles. The distress call apparatus is installed on a vehicle, when a dangerous case occurs, the person calling for help can press a distress-calling trigger key to continuously emit distress signal in wireless way; the distress signal can be received once the vehicle provided with the distress call apparatus enters into the effective range of the wireless distress signal, so as to facilitate salvors of a rescuing vehicle to find out the distress-calling vehicle, and assistance can be provided in person by the salvors according to the conditions of the scene of an accident, or be provided by the way of artificial alarming and assisting police or medical personnel to come to the scene of the accident in time. The method and the device of the invention emphasize the scene sense, and utilize the interdependent salvation to ensure that the police or the medical personnel can timelier and more accurately find out and trace the distress-calling vehicle by the assistance of the rescuing vehicle, which settles the problem of poor mobility of the present emergency call system, enhances the salvation effect, and not only reduces the establishment cost of a whole rescuing system, but also is convenient for concealed installation due to the small size of the device.

Description

technical field [0001] The invention relates to a method and a device for realizing a vehicle wireless call for help, in particular to a method and a device for realizing rescue through mutual assistance. Background technique [0002] At present, the calling device used on the vehicle and the method for realizing calling for help are relatively complicated. Usually, a central platform needs to be established, and the GPS module and the GSM mobile phone module are used together to realize the alarm. The GPS module realizes the positioning and tracking function of the vehicle, and the GSM mobile phone module realizes the message notification broadcast function such as SMS with the central platform. When the vehicle calls for help in an emergency, it sends a short message to the central platform. The short message contains the current latitude and longitude of the vehicle, the vehicle's own information and other relevant information. The central platform obtains the specific lo...

AI Technical Summary

Problems solved by technology

This multi-point (call for help point) to single point (central platform) call for help processing method generally has defects such as inaccurate positioning, alarm delay, and high operating costs.

Therefore, the application promotion range of present vehicle calling for help device is limited, also can't effectively protect driver's personal and property safety.
