Solution

For high-risk, complex scenarios such as emergency rescue, chemical production, public safety, and waterborne transportation, we provide intelligent, integrated solutions for emergency communications and rescue operations.

Air Breathing Apparatus Solutions

Positive-pressure air respirator solutions comprise five key components—air supply valve, respirator mask, backframe, pressure regulator, and pressure gauge—and can be flexibly configured and procured to meet your specific needs. We offer both individual component replacement and complete system integration, enabling features such as HUD display, voice amplification, communication, pressure monitoring, and audible/visual alarms to satisfy your customized requirements.

Communication in Complex Environments

In complex environments—such as underground mines, the interiors of high-rise buildings, tunnels, large industrial facilities, and disaster‑response sites—conventional wireless communications are often severely constrained by obstruction, multipath effects, electromagnetic interference, or damage to infrastructure. To ensure the reliable transmission of critical information, Zhengze integrates multiple technological approaches, enabling stable, low‑latency, and highly secure delivery of voice, video, positioning, and sensor data even in extreme or dynamically changing conditions, thereby providing robust communication support for mission‑critical operations.

Comprehensive Rescue

The comprehensive fire‑rescue positioning system is an integrated platform for data collection, transmission, command, and emergency‑call localization and search‑and‑rescue operations. It combines indoor and outdoor firefighter positioning, emergency‑call and search‑and‑rescue capabilities, interior‑attack information logging, air‑breathing apparatus pressure monitoring, vital‑signs monitoring, and personnel‑status tracking into a single solution. Leveraging a self‑organizing MESH network developed in‑house and dual‑channel 4G/5G transmission technology, the system enhances the reliability of information exchange and data transfer. With its intuitive operation, robust functionality, superior performance, and high practicality, it significantly safeguards the personal safety of firefighting personnel.

Artificial Intelligence Rescue Robot

The AI‑powered rescue robot solution is an intelligent emergency response system designed for complex disaster scenarios such as earthquakes, fires, mining accidents, floods, and hazardous chemical leaks. It integrates artificial intelligence, autonomous perception, multimodal communication, and specialized mechanical engineering. Its core objective is to swiftly access areas that are difficult or too dangerous for humans to reach within the critical “golden 72 hours,” carrying out essential tasks including life detection, environmental assessment, supply delivery, communication relay, and decision support, thereby maximizing search-and-rescue efficiency and survival rates.
