Internet of Things field video monitoring system based on low power consumption

Abstract

The invention discloses an Internet of Things field video monitoring system based on low power consumption. The system comprises a video acquisition end, a video server end and a video publishing server, the video acquisition end is connected with the video server end; the video server end is connected with the video publishing server. The system is novel in structural design, is based on a lightweight application layer protocol of a UDP protocol, transmits video data through increasing the data transmission time and then optimizes the display effect of the video through the processing of theserver side, meets the video monitoring application of a low-change-rate scene, and can improve the field video monitoring efficiency.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a low-power-consumption-based IoT field video monitoring system. Background technique [0002] The design of the video surveillance transmission system is mainly in the following two ways: [0003] (1) Laying cables. [0004] (2) Use microwave or 3G, 4G for transmission, and use wireless bridge or 3G, 4G video server to transmit the video, audio and control data returned by the front-end equipment to the monitoring center. The video and control signals from the front-end monitoring point to the monitoring center establish a wireless link through the wireless bridge. The wireless network adopts a point-to-point network transmission mode. The bridge and the antenna adopt a separate design. The high-performance, high-bandwidth, multi-functional, outdoor carrier-grade wireless equipment is used to connect the frequency feeder to the directional antenna. This method effecti...

AI Technical Summary

Problems solved by technology

To sum up the above two transmission methods, the cost of laying cables is high. At present, high-definition video transmission is mainly 720P, while 3G and 4G networks cannot meet the higher transmission requirements such as 1080P video, and the frequency range is narrow, which cannot meet the rapid transmission capacity. Growth and demand for wider spectrum resources

[0005] The advantages of the Internet of Things sensor network are convenient deployment, low power consumption, low cost, and can be deployed in relatively harsh environments, but the network bandwidth is low and the reliability is poor.

Therefore, various Internet of Things protocols (such as MQTT, GoAP) are designed to deal with this kind of network, but these protocols are not suitable for applications of large data transmission such as video surveillance.
