Smart Smoke Detection
Fires are always alarming, even terrifying. They kill people and ruin families with their destruction. It is critical that we enhance fire safety awareness and use firefighting equipment intelligently to minimize losses and damages. Smoke detectors are automated sentries, able to detect smoke in real time. If the density of smoke exceeds a predetermined threshold, a smart smoke detector will send information to the backend management platform and activate related devices such as alarm bells. The platform will then automatically send the information to the corresponding departments and alert the right personnel by voice messages or SMS.
However, traditional standalone smoke detectors cannot meet the requirements of smart firefighting. They report false alarms and cannot interact with people like the property owners, security guards, or fire fighters. Distributed installation is difficult and expensive. Power-hungry traditional smoke detectors require frequent battery replacements and are more expensive to maintain.
NB-IoT Enables Smart Smoke Detection
NB-IoT-based Smart Smoke Detection lack many of the disadvantages of traditional smoke detectors such as difficult cabling, short battery life, high maintenance costs, and an inability to interact with people. This solution is plug-and-play, easy to deploy, and thanks to using wireless communications technologies, requires no cabling. The smart smoke detector features low power consumption and a battery standby life of over 10 years. There is no need to frequently replace the battery which makes maintenance less expensive.
The solution can report on an ongoing fire in real time, and promptly report wide spectrum of potential issues. This valuable information can reduce property losses and save lives. The solution can also access a big data platform to help the government make critical decisions and eliminate fire hazards.
Smart Smoke Detection helps operators explore new opportunities, increase revenue, and develop entirely new markets. The solution enables ordinary residents to prevent household fires with only a minimal investment, and ensures the safety of the homes and the people who live there. Moreover, this solution helps the fire departments better prevent economic and physical losses.
Huawei and China Unicom (Shanghai) have jointly deployed 200 Hothink pilot smart smoke detectors in a subdistrict in Shanghai. When there is a fire, the alarm system will automatically inform the property owners, service personnel, and fire fighters using a text-to-speech (TTS) system. This can ensure prompt evacuation, minimize casualties, prevent economic and physical losses, and commercialize operations of public fire services.
Smart smoke sensors have been deployed nationwide. 30,000 smart smoke sensors have been deployed, and the number is expected to reach 100,000 by the end of 2017.
