Emergency wireless broadband communication system

Abstract

The invention provides an emergency wireless broadband communication system, which comprises a central base station and a multimedia mobile terminal. The central base station is used for receiving multimedia data transmitted by the multimedia mobile terminal through a wireless broadband network and transmitting the multimedia data to the multimedia mobile terminal through the wireless broadband network; and the multimedia mobile terminal is used for collecting the multimedia data after establishing connection with the central base station through access to the wireless network, transmitting the collected multimedia data to the central base station through the wireless network, and receiving the multimedia data transmitted by the central base station. The system can help the command center to flexibly master the actual situation of the emergency accident site, and has the advantages of high mobility, flexible networking and great economic significance.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a wireless broadband emergency communication system. Background technique [0002] The emergency communication system is a communication system that can be quickly established and used stably no matter when and where, regardless of the existing local communication conditions. Traditional emergency communication systems usually only use voice communication mode, such as mutual communication between telephones However, this method cannot intuitively understand the actual situation of the accident site, and the command and leadership cannot make accurate instructions. [0003] With the continuous development of network technology, network monitoring technology through the Internet has emerged, that is, multimedia acquisition devices such as cameras are installed in various places, and the collected multimedia data such as audio and video are transmitted to the monitoring ce...

[0002] The emergency communication system is no matter when and where, regardless of the local existing communication conditions, it can quickly establish a stable communication system. The traditional emergency communication system usually only uses the voice communication mode, such as the communication between the telephones. However, this method cannot provide an intuitive understanding of the actual situation at the place where the accident occurred, and the command and leadership cannot make accurate instructions

[0003] With the continuous development of network technology, network monitoring technology realized through the Internet appeared, that is, multimedia collection devices such as cameras are installed in various places, and the collected multimedia data such as audio and video are transmitted to the monitoring center through the Internet, and the monitoring center can receive The multimedia data to each multimedia acquisition device, and then give specific instructions through another communication system, such as a voice communication system. Obviously, in this way, a large number of multimedia acquisition devices need to be pre-configured in the fixed network, and the cost is relatively large. If there is no pre-installed camera device in the place where the accident occurs, the monitoring center cannot monitor the situation of the place where the accident occurs. Obviously, the ability to deal with emergencies is very poor, and the mobile performance is also very poor.
