Problems solved by technology

[0003] Due to the limitations of the firefighting environment and conditions at complex disaster sites, existing firefighting robots generally do not support real-time transmission of remote audio, video and sensor data, or use analog images + short-distance wireless remote control, which is not conducive to the rear commanders. Gain simultaneous access to live real-time data, images and voice information and make correct decisions

Abstract

The invention belongs to the technical field of fire-fighting communication, and particularly relates to a broadband wireless communication device for a fire-fighting robot. The broadband wireless communication device comprises a front-end transmission device and a rear-end receiving device. The front-end transmission device comprises a front-end power module, a front-end communication core board, a front-end video processing module, a front-end voice processing module, a front-end cavity filter, a front-end circulator, a front-end power amplifier and a front-end antenna. The rear-end receiving device comprises a rear-end power module, a rear-end communication core board, a rear-end voice processing module, a rear-end cavity filter, a rear-end circulator, a rear-end power amplifier and a rear-end antenna. According to the broadband wireless communication device for the fire-fighting robot, multi-channel audio and video transmission can be provided, high-speed data transmission is supported at the same time, and a communication protocol and a transmission system of the broadband wireless communication device are particularly suitable for multipath constructions like buildings with serious interference. According to the broadband wireless communication device, hybrid transmission of images, voices and data inside the same channel is supported, and the broadband wireless communication device has the advantages of being good in image real-time performance, high in voice compression ratio, short in data delay and the like.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting communication, and in particular relates to a broadband wireless communication device for a fire-fighting robot. Background technique [0002] The fire protection industry is an extremely important industry to ensure the safety of people's lives and property. When a disaster occurs, fire rescue and rescue personnel are faced with dangerous environments such as high temperature, strong heat radiation, flammable and explosive, toxic and harmful, and collapsed. Personal safety. As a special fire-fighting equipment, fire-fighting robots can replace firefighters in petrochemical, oil tank farms, large warehouses, stacks, buildings, etc. Firefighting vehicles and personnel cannot approach dangerous places to carry out firefighting operations such as reconnaissance, fire extinguishing, cooling, smoke exhaust, lighting and decontamination of chemically polluted places, so as to avoid casualties of...
