Solution Overview

Problem

Existing fire detection systems in battery energy storage facilities and other industrial facilities fail to detect the initial signs of overheating, gas emissions, smoke, and other early indicators of battery failure are essential to ensure timely and effective fire prevention and mitigation in these high-risk environments.

Innovation Solution

A multi-parameter cable-based linear fire detection system that effectively addresses the inadequacies of traditional fire detection methods in battery energy storage facilities and other industrial facilities. It overcomes the difficulties of previous fire detection systems by including 5 sensors: infrared sensor, along with an addressing module. These sensors are connected in series and linked to a signal processing unit that prevents false positives and precisely identifies the exact location of the fire. Additionally, the system features an air sampling function, utilizing an air tube with multiple inlets along the cable to continuously draw air samples for real-time analysis. This innovative system is capable of monitoring critical early indicators of fire, ensuring comprehensive coverage and timely intervention. This advanced detection method significantly enhances fire safety and reduces the risk of extensive damage in high-risk industrial environments.

Engineering Contradictions & Design Principles

1Reliability

If traditional point type smoke detectors and linear heat detectors are used, then the system structure is simple, but the detection sensitivity is low and comprehensive fire parameter monitoring is not achieved

Engineering Contradiction:

Solution Approach 1:

The patent combines multiple detection functions (heat detection, smoke detection, VOC detection, combustible gas detection, and infrared detection) into a single integrated linear detection cable system. The sensing modules are positioned along the cable at specific intervals, with each module containing multiple sensors that work together to provide comprehensive fire parameter monitoring, thereby achieving high detection sensitivity without requiring multiple separate detection systems.

Inventive Principle:

2Measurement precision

If traditional linear heat detection systems are used, then the system is easy to operate, but the fire location cannot be pinpointed accurately

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The detection cable is divided into multiple sensing modules positioned at specific intervals along the cable. Each sensing module is independently addressable and contains its own set of sensors. When a fire event is detected, the system can identify which specific sensing module detected the anomaly, thereby pinpointing the fire location along the cable route with greater accuracy while maintaining ease of operation through automated module addressing.

3Reliability

If traditional threshold alarm method is used, then the system is simple to manufacture, but false alarms and missed alarms occur due to lack of comprehensive fire environment consideration

Engineering Contradiction:

Solution Approach 1:

The system monitors multiple fire parameters simultaneously (temperature, smoke concentration, VOC levels, combustible gas levels, and infrared radiation) rather than relying on a single threshold parameter. The signal processing unit analyzes the combined data from all sensors to determine whether a true fire event is occurring, thereby significantly reducing false alarms and missed alarms while providing a more accurate representation of the actual fire environment.

Solution Approach 1:

The system is designed to detect early indicators of battery thermal runaway before a full fire occurs. The sensing modules continuously monitor for subtle changes in temperature, smoke, VOC emissions, and combustible gas levels that precede catastrophic battery failure. By detecting these preliminary signs of thermal runaway, the system enables early warning and intervention, providing critical response time to prevent extensive damage in battery energy storage facilities.
