CN203025907U - Smart phone based vehicle collision or drop alarm system - Google Patents

Abstract

The utility model relates to a smart phone-based vehicle collision or fall alarm system, which includes a plurality of smart phones and an alarm receiving server, each smart phone includes an acceleration sensor, a GPS module, a 3G communication module, a camera and a main control unit. The units are respectively connected to the acceleration sensor, GPS module, 3G communication module, and camera electrical signal, and the 3G communication module is connected to the alarm receiving server electrical signal. When the difference between the maximum acceleration and the minimum acceleration and the vertical acceleration measured by the acceleration sensors of multiple smart phones After the threshold is higher than the set threshold, it is judged whether an abnormal situation has occurred through the preset rules. When an abnormal situation occurs, the main control unit will upload the vehicle GPS position information and on-site photos to the alarm receiving server through the 3G communication module. The system has the advantages of accurate and timely alarm and simple structure.

Description

Smartphone-Based Vehicle Collision or Fall Warning System

technical field

The utility model relates to a vehicle collision or fall alarm system based on a smart phone.

Background technique

China, which has entered the era of popularization of automobiles, is facing the same problem of high incidence of automobile accidents as developed countries such as Europe and the United States. In order to minimize casualties and related property losses after the accident, we must obtain information such as the location of the accident, the number of passengers in the accident vehicle, and the damage to the vehicle in the shortest possible time; When the accurate information of the accident cannot be provided more when calling for help, relevant departments cannot provide timely rescue at all. The research on active alarm and self-rescue after automobile accident has important practical significance. European Union car accident warning usually relies on car-specific hardware implementation. After a serious traffic accident occurs to the vehicle, it will automatically dial the emergency number 112 in the European Union and report the location of the accident vehicle to the emergency station closest to the accident site. Its function is relatively simple, and the quality of equipment varies with automobile manufacturers and models. Domestic vehicle accident rescue is still basically at the stage of calling for help manually, and a few manufacturers have developed several vehicle-mounted self-rescue equipment. This type of equipment generally integrates sensor elements, GPRS communication modules, and GPS positioning modules, and its cost is high and the stability of the equipment is poor. Generally placed in the front of the car, it is easily damaged in a major traffic accident and cannot be called for help.

Utility model content

Based on the above deficiencies, the utility model discloses a smart phone-based vehicle collision or fall alarm system. When a driving car has an accident, it will bring a strong abnormal acceleration signal. According to the collision detection algorithm, the mobile phone will judge whether it is necessary to call the police. If it is necessary to call the police, it will use the mobile phone to take pictures, GPS positioning and networking functions, and report the situation to the rescue center in time.

The utility model adopts the following technologies: a smart phone-based vehicle collision or fall alarm system, including multiple smart phones and an alarm receiving server, each smart phone includes an acceleration sensor, a GPS module, a 3G communication module, a camera and a main control unit , the main control unit is respectively connected to the acceleration sensor, GPS module, 3G communication module, and camera electrical signal, and the 3G communication module is connected to the alarm receiving server by electrical signal. When the difference between the maximum acceleration and the minimum acceleration measured by the acceleration sensors of multiple smart phones And after the vertical acceleration is higher than the set threshold, judge whether there is an abnormal situation through the preset rules. When an abnormal situation occurs, the main control unit will upload the vehicle GPS position information and on-site photos to the alarm receiving server through the 3G communication module.

The utility model has the advantages of accurate and timely alarm and simple structure.

Detailed ways

Below in conjunction with accompanying drawing example the utility model is described further:

Example 1

A smart phone-based vehicle collision or fall alarm system, including 5 smart phones and an alarm receiving server 6, each smart phone includes an acceleration sensor 3, a GPS module 5, a 3G communication module 2, a camera 4 and a main control unit 1, The main control unit 1 is respectively connected to the acceleration sensor 3, the GPS module 5, the 3G communication module 2, and the camera 4 by electrical signals, and the 3G communication module 2 is connected to the alarm receiving server 6 by electrical signals. After the difference between the maximum acceleration and the minimum acceleration and the vertical acceleration are higher than the set threshold, it is judged whether an abnormal situation has occurred through the preset rules. The module 2 is uploaded to the alarm receiving server 6 .

Claims (1)

1. based on the vehicle collision of smart mobile phone or the warning system of falling, comprise multi-section smart mobile phone and warning reception server, it is characterized in that: every smart mobile phone comprises acceleration transducer, the GPS module, the 3G communication module, camera and main control unit, main control unit respectively with acceleration transducer, the GPS module, the 3G communication module, the camera electric signal connects, the 3G communication module is connected with warning reception server electric signal, after the difference of peak acceleration that the acceleration transducer of multi-section smart mobile phone records and minimum acceleration and normal acceleration are higher than setting threshold, whether abnormal conditions have occured by predefined rule judgment, by main control unit, vehicle GPS positional information and scene photograph are uploaded to the warning reception server by the 3G communication module when the abnormal situation.
