Communication method and system based on satellite positioning technique and on-board terminal device

Abstract

The invention discloses a communication method and system based on a satellite positioning technique and an on-board terminal device. The on-board terminal device comprises a backup power supply, an interface module, an on-board controller and an information sending module. The interface module is connected with the on-board diagnostic system of a vehicle. The on-board controller is used for starting the backup power supply and triggering the information sending module to send first short message information containing the vehicle position information when the interface module detects that the on-board diagnostic system stops supplying power. The information sending module is used for sending the first short message information containing the vehicle position information to a satellite system, so that the satellite system sends the first short message information to a customer service platform. The customer service platform sends help calling information to a fire-fighting system according to the vehicle position information. The method, the system and the device are not limited by an automobile power supply system. The short message information can be sent independently. Rescue time is fought for a user. Relatively high security assurance is provided specific to specific disasters such as flood disasters.

Description

technical field [0001] The present invention relates to the technical field of satellite communication, and more specifically, to a communication method and system based on satellite positioning technology, and a vehicle-mounted terminal device. Background technique [0002] With the development of the automobile industry, automobile safety and automobile emergency alarm and help mechanisms have attracted the attention of various media and users. Especially in the face of catastrophic natural disasters, the necessary car alarm and car safety functions have become an important part of protecting people's lives. On July 21, 2012, Beijing suffered a torrential rain disaster. In this torrential rain, 76 people died, and a large part of them died because they were trapped in cars. So far, in view of the situation that the user is trapped in the car, if the body is flooded, the user has very limited ways to call for help, and it is impossible to quickly notify the fire and public...

Problems solved by technology

However, this mode is based on the premise that the battery can supply power normally and the GPS can communicate through the data pipeline. If the car is basically flooded in the event of a severe weather disaster like 721, the above functions are likely to fail to work. Then the It is difficult to complete the above communication
