Caltta Creates ''All-Scenario, Highly Reliable, Strongly Explosion-Proof'' Emergency Communication Solution

Project Background

Hebei Province has complex geological structures and is an industrial powerhouse with numerous chemical plants and concentrated high-rise buildings, posing a high risk of urban fires and industrial accidents.

As the core force safeguarding the "capital's moat" safety barrier, the Hebei Provincial Fire and Rescue Corps is tasked with ensuring the safe development of Beijing-Tianjin-Hebei integration and handling multi-disaster coupled incidents. Under the deployment of the provincial government, the Ministry of Emergency Management, and the National Fire and Rescue Bureau, the province's fire rescue teams are accelerating the construction of an intelligent command system and modern equipment, focusing on building a new pattern of disaster prevention and rescue that is both "three-dimensional and specialized."

Communication Needs

During major disasters such as fires, earthquakes, floods, mudslides, and major traffic accidents, the disaster site is usually in an information blackout state. For emergency rescue scenarios involving complex buildings and significant natural disasters, the Hebei Fire and Rescue Corps needs to establish a consistent, orderly emergency command and communication system to provide robust communication support for disaster rescue operations.

Meanwhile, when fire rescue teams are faced with environments such as chemical parks and hazardous material warehouses, where there are flammable and explosive gases or dust, they must use specialized explosion-proof communication equipment to ensure emergency communication and personal safety.

Solution

Caltta Hightech deeply participates in the construction of the "three-dimensional and specialized" rescue system of the Hebei Fire and Rescue Corps by offering the "intelligent networking + explosion-proof terminals" dual-core solution, providing the corps and municipal brigades with a "full-scenario, highly reliable, explosion-proof safety" communication solution:

Core Network Equipment

Deploy the SmartLink600 voice ad hoc network base station to build a centerless, self-healing communication network.

Terminal Safety Assurance

Equipped with PH690Ex digital explosion-proof walkie-talkies and PH690 professional digital walkie-talkies, ensuring communication safety in high-risk gas, dust, and other environments.

Technical Integration Application

The comprehensive application of voice ad hoc network PDT/DMR protocol compatibility and multi-hop relay technology to unblock the command chain, building a safe, professional, and reliable communication system.
