Experience the "Wisdom Fan" of modern fire protection

In recent years, the national public security fire system has accelerated the construction of “smart fire protection”, continuously improved the scientific and technological content of fire prevention and fire fighting, and promoted the scientific, chemical and intelligent fire protection work. Recently, the reporter came to Jiangsu and Zhejiang provinces to interview and experience the “wisdom fan” of modern fire protection.

"Intelligent CT" to accurately detect electrical fire hazards

On December 8, 2017, the Xuzhou City Public Security Fire Brigade Command Center of Jiangsu Province received an electronic alert to accurately display the sudden increase in the temperature of a certain electrical equipment in Liuzhou Primary School in Xuzhou City, exceeding the set safety threshold. The fire detachment on duty immediately commanded the firefighters to rush to the scene to investigate, and found that the school's construction team temporarily connected to high-power electrical equipment such as mixers and electric welders, and the site did not have professional electricians and safety personnel, firefighters immediately stopped.

This vivid interpretation of the great role of the Xuzhou Electric Fire Network Monitoring Platform in Jiangsu Province in actual fire fighting. Since 2017, the Xuzhou Public Security Fire Brigade has combined fire risk assessment and big data information technology to develop and apply an electrical fire network monitoring platform, which has greatly improved the intelligent fire prevention and control capabilities of electrical fires. “In the past, the rectification of electrical fire hazards relied entirely on manpower, which was time-consuming and labor-intensive. Today, this platform is like 'smart CT', which is aimed at the 'pathogenic source' of electrical fire hazards, achieving digital precision and full-range monitoring.” Jiangsu Province Liang Jun, deputy head of the Xuzhou Public Security Fire Brigade, said.

According to reports, the monitoring platform installs the IoT acquisition module on the user's power line, collects voltage, current, temperature and other data in real time, and continuously monitors the overvoltage and overcurrent and residual current overruns that may occur in the line. The safety hazards found in the offline inspection will also be recorded in the monitoring platform.

In addition, according to the user's electricity consumption indicators, the monitoring platform will comprehensively judge the precursors of electrical fires, and conduct fire warnings for intensive places such as nursing homes and schools, and implement active interventions such as automatic power outages. The monitoring platform will also send warning information to the fire department and management responsible person through SMS, webpage, WeChat, etc., to remind people to check for potential safety hazards, and request real-time feedback to the platform for rectification.

"The platform can also intelligently identify the general units and key units of electrical fire hazards based on user warning data and power behavior data, and assist the grassroots fire supervisors to conduct more targeted supervision." Liang Jun said.

Up to now, the monitoring platform has been installed in 227 units of civil affairs, medical care and education in Xuzhou, Jiangsu Province, and found and disposed of more than 7,800 electrical fire hazards, effectively preventing 6 electrical fires from happening. Fire accident.

"Wisdom of Things" to solve the fire problem of high-rise buildings

The Country Garden Phoenix Community, Zhenjiang City, Jiangsu Province, has 175 high-rise buildings under construction and has been built. It is expected to have a population of 200,000. This poses many challenges to fire safety: First, there are many high-rise buildings, personnel gathering, high fire risk, and fire fighting. The rescue is difficult; the second is that the level of property management is uneven, the construction fire facilities are not in good condition; the third is limited police power, and it is difficult to fully cover daily fire safety supervision. “It is not feasible to simply increase manpower to promote fire protection supervision. To achieve modern fire control, we must carry out concept innovation and make a way out to science and technology.” Dou Liyan, deputy head of the public security fire brigade of Zhenjiang City, Jiangsu Province.

"Water level 6.3m, water pressure 0.3mpa, equipment is normal, the state is normal..." On the big screen of the fire control center of the Phoenix Community, whether the water level of the fire pool is normal, whether there is water in the outdoor fire hydrant, whether the fire protection facility has failed, etc. At a glance. With the help of more than 10,000 sensors in the community, the staff of the fire control center of the community has “Clair Eyes” and “Shunfeng Er”. The intelligent fire monitoring system provides 24-hour continuous analysis and early warning to the community fire protection and distributes them in real time. Ensure the fire safety of the community.

On October 10, 2017, Mr. Wang, who lived on the 8th floor of Fengyiyuan, the restaurant, cooked food at home. During the period, he took the express to the downstairs. About 10 minutes, there was white smoke in the kitchen, and the pungent coke was emitted. taste.

The community fire control center immediately received the fire alarm of the 8th floor of the building. The fire company administrator of the property company rushed to the scene at the first time and found that the natural gas connection hose leaked and burned, and immediately shut off the natural gas valve, and extinguished the fire part with a fire extinguisher . Avoid the fire.

This real-time interactive management benefits from the “Smart Connect” fire protection system. Nowadays, the Phoenix Community has built seven “wisdom modules” such as the fire protection facility network monitoring and management system, the intelligent fire water source system and the electric bicycle intelligent charging system. The community has also achieved zero records of fire accidents and zero complaints from fire management. Effective exploration of cracking high-rise building fire prevention problems has been made.

"Four in one" to create a comprehensive intelligent fire protection system

When you go out on holiday, you don't have to worry about the fire in your home. The intelligent system controls the high-load household appliances. When the business owner goes out, the electrical fire in the factory is hidden by the remote monitoring system. Once the current is abnormal, the monitoring background can pass the mobile APP for the first time. SMS to inform business managers...

In Zhejiang, these "smart fires" of "Internet + fire basic prevention and control" are getting closer and closer to the people. "We are using the 'smart fire' construction as the starting point, and strive to achieve the errands of the data, let the fault speak, and eliminate the fire in the bud." According to Yang Guohong, the captain of the Zhejiang Public Security Fire Brigade, by the end of 2017, Zhejiang Province Each city in the district has established intelligent power, smart water, remote monitoring and intelligent early warning platforms.

There are many urban villages in Zhili Town, Huzhou City, Zhejiang Province, and there are many groups of rented houses and industrial plants. The fire safety hazards are more serious. At 4 o'clock on the afternoon of November 23, 2017, a renter mobile phone charger in Zhili Town Mall was short-circuited, generating a lot of smoke, which triggered the indoor intelligent smoke detector. Pregnant women and the elderly in the next room immediately evacuated after hearing the buzzer alarm.

The avoidance of this accident is due to the “smart warning” platform of Huzhou City. The platform includes a wireless intelligent stand-alone smoke detector, wireless manual alarm button, wireless sound and light alarm and wireless intelligent gateway controller. When a smoke detector detects smoke, the buzzer will automatically alarm. At the same time, the multi-level alarm mechanism will automatically send reminders to the accommodation staff, business owners, grid staff and other related personnel through the mobile APP.

In addition to the “smart warning”, Huzhou has also built a “four-in-one” all-round “smart fire” system covering intelligent supervision, smart water and smart electricity. Thanks to the application of the system, the number of fires, property losses, deaths and injuries of people in Huzhou in 2017 decreased by 45.9%, 53.9%, 58.5% and 40% respectively. "In the future, we will also establish Huzhou Firefighting Internet of Things and cloud platform to create an upgraded version of 'Smart Fire', so that the fire prevention and control information data will be 'live'." Wang Xiongxiong, political commissar of the Huzhou Public Security Fire Brigade of Zhejiang Province, said.
