Online status detection method and system of vehicle terminal

Abstract

The invention discloses an online state detecting method of a vehicle-mounted terminal, comprising the following steps of: actively sending an online signal to a server side by the vehicle-mounted terminal at a starting moment; dispatching a dynamic memory space for the vehicle-mounted terminal after the online signal is received by the server side, wherein the dynamic memory space is used for storing service data relevant to the vehicle-mounted terminal; receiving a service request sent by the vehicle-mounted terminal; generating service data according to the service request and storing the service data in the dynamic memory space; sending the service data in the dynamic memory space to the vehicle-mounted terminal; periodically sending an online data checking signal to the vehicle-mounted terminal and waiting for an online state fed back by the vehicle-mounted terminal; and if the online state fed back by the vehicle-mounted terminal is not received within the preset time or an offline signal sent actively by the vehicle-mounted terminal is received, clearing up the service data stored in the dynamic memory space and releasing the dynamic memory space. By using the online state detecting method, the online state of an automobile can be actively monitored in real time, and relevant service can also be actively provided.

Description

technical field [0001] The invention relates to the field of auto parts, and more specifically, to a method and system for detecting an online state of a vehicle-mounted terminal. Background technique [0002] The networking of automobiles has become a trend. When a driver is driving a car, it has become a design requirement for a new model to be able to keep in touch with the service desk or the outside world in real time through the Internet. [0003] At present, among the vehicle network systems, relatively successful examples are General Motors' "Onstar" system and Toyota Motor's "G-BOOK" system. [0004] GM's OnStar mainly uses wireless technology and Global Positioning System (GPS) satellites to provide comprehensive wireless services to cars. To put it simply, General Motors equipped with OnStar is equipped with collision sensing instruments on the front and rear anti-collision bars, on the doors, on the airbags inside the car, and even on the roof. Once the collisio...

AI Technical Summary

Problems solved by technology

[0007] 1) It cannot actively monitor the car's networking status in real time, and the car owner needs to manually turn on the networking device before enjoying the networking service

[0008] 2) It is still not possible to actively provide relevant services based on information such as the driving status and location of the vehicle, and it is not enough in terms of active services
