Industry Overview

The fire command center serves as the central nervous system for firefighting, rescue, and emergency response operations across the entire city. It functions as a centralized platform for integrating and sharing intelligence and information related to all such incidents. Its core capabilities must include executing unified command from both the command center and the disaster scene, rapidly establishing a command structure, and implementing effective deployment and dispatch strategies to minimize losses caused by disasters.

In the current era where information technology permeates every corner of society, the development of the Fire Communication and Command System must align with broader social and technological trends. It will leverage existing urban communication infrastructure and public security information networks to establish a multi-level vertical command and dispatch network connecting the detachment, brigade, and squadron levels. Simultaneously, it will build a horizontal collaborative network interfacing with command systems of emergency management agencies, command and control systems, and other disaster relief-related units.

The system will integrate various advanced technologies to deploy practical, efficient, and specialized application systems for fire communication and command operations.

Solution

Fire Emergency Requirements: Multiple relay devices can rapidly establish a temporary on-site emergency communication network, providing voice communication for firefighters at the rescue scene. Multiple radio devices offer broadband links for real-time transmission of on-site images and videos, providing commanders with more comprehensive information for decision-making. Both voice and video data can be transmitted to the on-site command center, allowing commanders to formulate the optimal response plan based on real-time situational data.

Current State of Fire Emergency Response: Firefighting and rescue operations during sudden or major disasters are often characterized by extended durations, vast operational areas, and harsh conditions. These scenarios pose significant new challenges to fire command systems and the performance of equipment. Under such circumstances, notable shortcomings are often exposed in areas like emergency command communication support capabilities and the technical level of emergency rescue equipment.

Design Requirements: The system's hardware and software design adopts a modular, scalable architecture with standardized components. This facilitates the system's adaptation to various transmission network systems with different specifications and functional requirements. Since the system is built using a model of configurable devices, configurable policies, and configurable software modules, upgrading hardware or software can be done without affecting the uninterrupted and secure operation of the system and without impacting equipment at other sites.

Key Features: The system enables voice and video communication among fire emergency rescue personnel. When encountering obstacles ahead or unknown areas, drones can be deployed for aerial observation. The drones can also act as relay nodes in a multi-hop link, establishing a communication pathway between the on-site command post and rescue personnel. Simultaneously, on-site audio and video signals are transmitted from the command post to the rear command center via satellite link, enabling unified and coordinated command between front-line and rear operations.

Application Objective: The solution leverages multipath signals reflected by obstacles to provide more robust communication capabilities. Utilizing wireless ad-hoc network communication equipment that supports automatic relaying and multi-hopping, it enables wireless voice intercom and HDMI/network video input between nodes without the need for a central base station. It provides powerful communication support in complex environments such as fire emergencies

Environmental Context

In the event of a fire, this solution facilitates reliable on-site voice communication and establishes a field command and dispatch center.  

Local Area Network Coverage
   When a high-rise urban building catches fire, firefighters can carry and deploy digital wireless portable repeaters based on the situation to ensure signal coverage and device interconnection, thereby forming a unified voice communication network.  

Underground Network Coverage
   High-rise urban buildings often feature concrete structures in underground areas, which severely block ground network signals. Firefighters can carry individual portable devices to ensure network coverage in underground zones. These devices can wirelessly connect with wireless relay equipment deployed in underground floors, enabling seamless voice communication between above-ground and underground areas via the same network.  

On-site Command and Control Center
   Multiple relay devices can quickly establish a temporary emergency communication network on-site, providing voice communication for rescue firefighters.  
   Multiple portable devices provide broadband links for real-time transmission of on-site images and videos, offering commanders a more comprehensive basis for decision-making.  
   Both voice and video data can be transmitted to the on-site command center. The MESHCOM ad-hoc networking equipment is based on a decentralized, self-organizing communication network, featuring long-range coverage, high bandwidth, flexible deployment, and immediate readiness upon power-on. It is applicable in scenarios such as fire emergencies, civil defense emergencies, urban management law enforcement, environmental monitoring, "three-preventions" emergency response (flood, drought, windstorm), water conservancy and flood control, power emergency repair, railway rescue, maritime patrol, port monitoring, forest fire prevention, oilfield security, and live TV broadcasting. It is suitable for high-quality real-time mobile video transmission in various complex environments, including urban areas, maritime settings, and mountainous terrain.
