Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0030] refer to figure 2 , the method for the 3G module to preempt access when the vehicle collides in this embodiment includes:

[0031] Step S21, when the antenna module processor detects a vehicle collision, it sends a preemption command to the 3G module;

[0032] Step S22, the 3G module interrupts the communication with the host processor after receiving the preemption command;

[0033] Step S23, the antenna module processor takes over and controls the 3G module.

[0034] In step S21, when a vehicle collision occurs, when the antenna module processor sends a preemption command to the 3G module, it also sends a command to release the control right of the 3G module to the host processor, after the host processor receives the command to release the control right of...

Abstract

The invention provides a vehicle-mounted device and a method for preempting access by a 3G module when a vehicle collides. The method for preempting access by the 3G module includes: when an antenna module processor detects a vehicle collision, it sends a preemption command to the 3G module; the 3G module After receiving the preemption instruction, the communication with the host processor is interrupted; the antenna module processor completely takes over and controls the 3G module. The invention can make the antenna module processor seize the control right of the 3G module in time when the vehicle collides, and solve the problem of access conflict.

Description

technical field [0001] The invention relates to a vehicle-mounted device and a method for preempting access by a 3G module when the vehicle collides. Background technique [0002] refer to figure 1 , some vehicle-mounted devices in the prior art include a host processor (CPU) 11 , an antenna module processor (CPU) 12 and a 3G module 13 , wherein the 3G module 13 is jointly controlled by the host processor 11 and the antenna module processor 12 . The host processor 11 uses the 3G module 13 to send and receive network data to realize various application functions of the vehicle equipment, and the antenna module processor 12 uses the 3G module 13 to perform communication during collision rescue. [0003] When the collision occurs, since the host processor 11 is usually in the Internet access state, the access of the antenna module processor 12 and the host processor 11 to the 3G module 13 conflicts, causing the antenna module processor 12 to fail to obtain the control authorit...
