Fire fighting robot communication control
business background
Underground multi-storey buildings have complex structures, thick concrete steel walls, and many underground metal reflection sources. Existing wireless communication equipment has small signal coverage, large signal loss and fading, and poor resistance to multipath effects when used in such complex environments. Shortcomings such as limited bandwidth cannot completely solve the problem of stable transmission of information. The establishment of a broadband emergency communication system capable of stably transmitting video and audio in the underground building complex to respond to emergencies and realize image detection of complex underground environments has always been valued by the fire department, and it is also one of the problems that the communications industry needs to overcome.
After years of hard work, the underground emergency communication equipment of the new MESH fire-fighting robot communication control system has solved the problem of underground emergency communication. At the same time, the system products have the characteristics of simple installation, flexible use, simple operation, etc., and can be widely used in public security, fire protection, civil air defense, armed police, troops, electric power, petroleum, transportation and other departments.
An Introduction
Long-distance emergency communication solution The underground emergency communication system is mainly composed of WiFi module Mesh individual image transmission, Mesh repeater, Mesh base station and corresponding individual image transmission, headset, handheld microphone, interface cable and other accessories. It is a kind of A mobile broadband wireless communication transmission system designed with a brand-new "wireless mesh network" concept. The system adopts the same-frequency networking technology, supports multi-hop relay, and each node can move randomly, and the route can be quickly reconstructed when the system topology changes rapidly. The communication system uses the multi-hop relay of Mesh equipment to create a stable broadband communication link between internal attackers and the on-site command, realizes the real-time transmission of on-site audio, video and data information, and realizes visualized command and dispatch. In addition, the information of the communication command vehicle can also be transmitted back to the command center through 5G LTE private network, 5G public network or satellite communication network.
Program features
◆Software radio architecture It adopts a general hardware platform, supports dynamic loading and unloading of waveforms, and can configure parameters such as operating frequency, bandwidth, transmit power, modulation rate and network topology online according to changes in actual channel conditions and user status.
◆Broadband Mesh ad hoc network does not rely on base stations, efficiently and quickly form a centerless wireless broadband network. It supports multi-hop relay, which can effectively expand the coverage radius of the wireless network.
◆The WiFi module network has the characteristics of automatic routing, self-organization, self-healing, and automatic realization of chain, star and other network topologies.
◆One machine with multi-mode, ready to use any node device can be used as an information collection node, relay node or information output node at the same time.
◆All-IP networking, easy to interconnect, provide IP interface, can realize interconnection with other IP equipment.
◆Convergent communication hybrid networking, with both a central 5G LTE private network command network and a non-centralized MESH ad hoc front-end combat network. The WiFi module long-distance emergency communication solution not only solves the underground mutual communication in complex environments The difficult problem of coordinated operations has also solved the need for the back-end command to understand the progress of forward operations in real time.
