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 copied to mobile devices such as U disks.
However, when a major traffic accident (spontaneous combustion, arson, violent impact) causes damage to the storage device, video backup cannot be achieved
The purpose of this patent is to simplify the operation of video copying. It is said to be a backup. The actual and accurate statement should be "simplified operation of copying". In the actual use process, it does not actually play the role of backup.

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 f...

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.
Description
technical field [0001] The invention relates to the monitoring field, in particular to a method for setting audio and video backups on the vehicle-mounted equipment of public transport. Background technique [0002] Vehicle-mounted DVR equipment has become an important tool and method for daily bus inspections. The use of audio and video data can effectively supervise and standardize the driver's driving behavior. It can also be used as an important means of supervision and investigation of passengers' uncivilized behavior. important tool for clarification. [0003] With the rapid development of the economy, the urban traffic is becoming more and more congested, and major traffic accidents occur from time to time; incidents of bus spontaneous combustion and artificial arson also occur. Vehicle audio and video data can effectively find out the cause of the accident and reproduce the accident process. How to ensure the integrity of audio and video data is a problem that must...
