Problems solved by technology

Its disadvantages are: the cost is high, and if a major traffic accident (self-combustion, arson, violent impact) causes damage to the storage device, the data will be completely lost;
However, this method can only be used as a means of post-event inspection, that is, after an accident, it can be used as a simple method to retrieve videos, and it can be operated without professionals, and the specified videos in the DVR device can be copie

Embodiment Construction

[0021] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] As a concrete example, see figure 1 , a method for backing up audio and video recordings of bus-mounted equipment of the present invention, comprising the steps of:

[0023]Step 1. The WIFI routers on each bus have different priorities, and the priority list is set by the central server located in the parking lot and sent to each vehicle-mounted device;

[0024] Step 2. The vehicle-mounted device on the bus searches for nearby vehicle-mounted devices through its WIFI module, obtains the priority of the router of each vehicle-mounted device according to its priority list, and connects to the vehicle-mounted device corresponding to the searched highest priority router, Obtain the number of vehicle-mounted devices on the vehicle where the router is currently receiving backups. If it is less than 2, skip to step 4; if it is greater than 2, wait for

Abstract

The invention discloses a method for backing up audio and video in bus on-board equipment. The method includes the steps: 1, an on-board device to be backed up searches for and connects to a router of a nearby on-board device through a communication module of the on-board device to be backed up, thereby being in communication connection with the on-board device; 2, audio-video data to be backed up, in the on-board device to be backed up, is backed up to the on-board device. In order to ensure transmission quality, a prior step is performed in the step 1: to be specific, a priority list describing priorities of the routers of on-board devices is established, and the priority list is released to the on-board devices; When the on-board device to be backed up searches for the nearby vehicular devices through the communication module of the on-board device to be backed up, the priorities of the routers are obtained through the priority list, the highest priority one of the routers that the on-board device to be backed up searches for is connected, and a connection with the on-board device corresponding to the highest priority one of the routers is created.
