Abstract

The invention belongs to the technical field of network monitoring, and discloses a wireless transmission method and device, an audio and video collection terminal and a monitoring system. The methodcomprises the following steps: acquiring environment condition information in a mine, wherein the environment condition information at least comprises an environment image and an environment audio; performing real-time transmission protocol encapsulation on the environmental condition information to obtain an environmental condition data frame; segmenting the environment condition data frame intoenvironment condition data frame groups with a preset number of frames, and copying all the environment condition data frame groups with a preset number to obtain an environment condition data frame group set; and allocating each environment condition data frame group included in the environment condition data frame set to different network abstraction layer units and transmitting the environmentcondition data frame groups to a target server in parallel. According to the wireless transmission method provided by the embodiment of the invention, the environmental condition data to be transmitted are respectively transmitted after being segmented and copied, so that the data loss during mass data transmission can be avoided while the transmission efficiency is ensured, and the data transmission accuracy is ensured.

Description

technical field [0001] The invention belongs to the technical field of network monitoring, and in particular relates to a wireless transmission method, device, audio and video collection terminal and monitoring system. Background technique [0002] The video monitoring system is a comprehensive system integrating computer interactivity, comprehensive multimedia information, communication distribution and real-time monitoring. Using the video surveillance system, the real-time images and data of the monitored site can be accurately, clearly and quickly transmitted to the monitoring center server, and the monitoring center can understand and grasp the current situation of each monitored site in real time and directly In order to make corresponding response and processing directly according to the situation of the monitored site. [0003] Some existing simple wired communication equipment in coal mines often break the wired transmission cable due to the collapse of the tunnel,...
