Embodiment 1

[0030] This embodiment discloses an ECALL system terminal combined with a video system. When the eCall function of the ECALL system terminal is activated, in addition to performing the original data upload and voice call, it can automatically start the video system configured in the car for image or The video is shot and uploaded to the PSAP, so that the PSAP operator can have a more intuitive understanding of the accident situation through the video or image, so as to achieve the purpose of more accurate and rapid rescue.

[0031] The ECALL system terminal of this embodiment, such as figure 1 As shown, it includes: network connection module NAD, system on chip SoC, power module, backup battery and video system. Battery, video system, network connection module NAD, system on chip SoC connection; network connection module NAD is used to send shooting instructions to the video system, and upload received images or videos to PSAP, and the video system is used to The shooting com...

Embodiment 2

[0045] This embodiment discloses a rescue method for an ECALL system terminal combined with a video system. The method is based on the ECALL system terminal combined with a video system described in Embodiment 1, such as figure 2 As shown, the method includes:

[0046] S10: When the ECALL function of the ECALL system terminal is activated, the original data upload and voice call are performed first, and then the network connection module NAD of the ECALL system terminal sends a shooting command through VBus according to the network status and the power supply status of the power supply module of the ECALL system terminal to the video system.

[0047] S20: The video system captures images or videos according to the received shooting instructions, and converts the captured images or videos into a specified format and sends them to the system-on-chip SoC through VS1; at the same time, sends a signal of completion of image or video transmission to the network through VBus The ne...

Abstract

The invention relates to an ECALL system terminal combined with a video system and a rescue method. The ECALL system terminal comprises a network connection module, an on-chip system and the video system, wherein the network connection module is respectively connected with the on-chip system and the video system, and the on-chip system is connected with the video system; the network connection module is used for sending a shooting instruction to the video system, the video system executes image or video shooting according to the shooting instruction, converts the shot image or video into a specified format and then sends the image or video to the system on chip, and the on-chip system carries out data format conversion on the received image or video and then sends the image or video to the network connection module; and the network connection module uploads the received image or video to the PSAP. According to the invention, the video system is added on the basis of the original ECALL function module so as to realize image or video shooting and uploading functions, so that PSAP wiring personnel and rescue organizations can obtain on-site actual conditions which are richer and more accurate than data and voice, and the ECALL system terminal is very beneficial to rescue preparation and rapid rescue.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted ECALL equipment, in particular to an ECALL system terminal combined with a video system and a rescue method. Background technique [0002] ECALL is an emergency call system for automobile accidents, which includes a vehicle-mounted system terminal (subsequently referred to as a terminal, such as T-box), a public land mobile communication network PLMN (Public Land Mobile Network), a public safety answering point (Public safety answering point, hereinafter referred to as PSAP) and corresponding rescue organizations. The ECALL terminal installed on the car can be automatically activated through the internal sensor in the event of a car collision, rollover, etc. After being activated, it will connect to the PLMN and establish contact with the PSAP, and then the terminal will upload vehicle-related information to the PSAP (such as vehicle location , vehicle characteristics, time and other info...
