(1) Achievement Overview:
The smart fire early warning system based on NB-IoT consists of perception layer devices, NB-IoT network, wireless connected fire warning monitoring platform, and terminal App. The perception layer devices include independent smoke fire detectors with wireless connectivity, independent temperature fire detectors, independent combustible gas detectors, and independent electrical fire monitoring detectors. This system aims to address the lack of effective fire warning and control measures in fire safety “lowlands” such as residential homes, “nine small places”, shared spaces, cultural heritage buildings, and ancient towns. It comprehensively perceives and analyzes parameters such as fire, electricity, gas, water, video, and environment in protected locations, enhancing the fire warning detection capability, product battery life, system alarm timeliness, and system operational stability of the wireless connected fire warning system.

(2) Functional Features:
1. Independent fire detectors are insect-proof and resistant to dust pollution;
2. Fire alarm verification logic and remote video fire confirmation;
3. Independent fire detectors have network signal quality monitoring functions;
4. Suitable for electrical fire monitoring in use places with open and closed residual current sensing technology;
5. Multiple information push methods such as voice calls, SMS, and App;
6. The platform achieves grid-based permission management;
7. Wireless connected devices are low power consumption with long battery life;
8. Simple device installation with low system deployment costs;
9. High reliability of large-capacity networking for perception layer devices.
(3) Performance and Technical Parameters:
1. Time for independent fire detector fire warning/alarm information transmission to monitoring platform: <30s.
2. Time for alarm of independent fire detector removal, low battery, etc.: ≤100s.
3. Time for offline fault alarm of independent fire detector: ≤24h.
4. Information push time: ≤10s.
5. Battery lifespan: ≥3 years.
Comparison with similar domestic and international equipment:
1. Based on NB-IoT narrowband cellular public network, combined with battery optimization power-saving technology, it improves network scale, receiving sensitivity, and coverage, achieving a balance with low power consumption requirements.
The system effectively solves the problem that independent fire detectors can only alarm locally and cannot transmit alarm signals remotely. Based on the authorized frequency band cellular public network, the channel is clean, reducing investment costs, and the reliability and stability of the network are high. In urban environments, system capacity can expand to tens of thousands of points, and communication distance can reach kilometers, capable of communication through one concrete wall, with battery life lasting over 3 years.
2. Based on multiple information interfaces and hierarchical permission settings, the system meets the actual fire prevention and control needs of residences, small places, shared spaces, and temporary buildings.
The system cloud platform can access various independent fire detection and early warning information, has functions for information access, processing, and alarm classification with permission push, and has interfaces for linkage with video monitoring systems, utilizing video resources for fire alarm confirmation.
Comparison of this project with existing domestic and international systems is as follows:
|
Comparison Item |
This Achievement |
Existing Domestic and International Systems |
|
Compliance and Reliability |
Completed NB-IoT compliance testing, wireless performance testing, obtained network access permission, and fire product certification |
Insufficient testing and inspection in terms of electromagnetic performance and compliance, some products even lack network access permits, considered illegal access |
|
Alarm Push Function |
Reliable alarm push, multiple push reminders via App, SMS, and phone during alarms to prevent missed alerts, with delivery confirmation |
Only has single push function via App, SMS, or phone |
|
Integrated Types of Detectors |
Diverse product types covering all monitoring means related to water, electricity, fire, gas, and video monitoring in residences and small places, can be deployed as needed to form a comprehensive prevention system; has open and closed electrical fire monitoring means, installation of electrical fire monitoring systems does not require power or network interruption |
Relatively single types, insufficient consideration of protection objects, environmental features, and application scenarios; installation of electrical fire monitoring requires power interruption and disconnection, affecting existing building operations, leading to user resistance |
|
Phone Mute Function |
Practical function: has phone mute function after alarm, close to ordinary users |
Requires users to press the mute button on the detector, user feedback is poor |
|
Network Signal Monitoring Function |
Strong applicability of networking performance, has network signal quality monitoring function |
Manufacturers and operators have difficulty in delineating responsibilities when network issues arise |
