Wireless communication command system for emergency rescue scene

Abstract

The invention relates to a wireless communication command system for an emergency rescue scene. The system comprises a scene information acquisition and wireless transmitting portable device, a multi-frequency point wireless access and transmitting device, a wireless receiving device and scene information processing equipment, wherein the wireless receiving device is connected with the scene information processing equipment and directly receives signals transmitted by the scene information acquisition and wireless transmitting portable device; and the multi-frequency point wireless access andtransmitting device is connected with the wireless receiving device, receives the signals transmitted by the scene information acquisition and wireless transmitting portable device, and forwards the received signals to the wireless receiving device. The system can realize wireless audio and video command of a disaster scene aiming at a complex environment, fuse audio, video and data transmission together by using the international advanced wireless communication technology, avoid wireless shielding problem under the complex environment by adopting the advanced mobile relay idea, prolong the length of an information communication link, and strengthen the wireless signal intensity.

Description

technical field [0001] The invention relates to an on-site wireless communication command system for emergency rescue. Background technique [0002] In recent years, with the rapid growth of the national economy and the acceleration of the urbanization process, the city's area, population, industrial scale and quantity are rapidly expanding, and the city's functions are becoming increasingly complex. Advanced disaster relief equipment can no longer meet the complex modern rescue missions. How to achieve "rapid response and correct decision-making" and improve the rescue efficiency of the entire army has become the key to the success of the mission. Single-channel information collection and independent voice communication in a simple environment can no longer meet the needs of modern disaster relief sites. How to quickly build a temporary information and communication network at the scene of a disaster accident in a complex environment, and comprehensively grasp the first-han...

Problems solved by technology

This will inevitably lead to an increase in the overall procurement cost of the virtual integrated environment

Moreover, due to the limitation of frequency bandwidth, this technology cannot form a real wireless communication network at all.

Due to the above-mentioned limitations of 340MHz microwave technology, and the relatively backward application technology, it is impossible to realize the real wireless communication command system for emergency rescue in the complex environment
