Taking the Youth Olympic Games as an opportunity to build wisdom fire in Nanjing

What can a large city activity bring to the city? Due to the holding of the Olympic Games, the information technology of fire prevention in Nanjing is advancing at an accelerating pace, innovatively resisting the emergency response system for urban disasters and expanding the remote monitoring system for urban fire alarms. With the Youth Olympic Games as a springboard, Nanjing’s “wisdom firefighting” construction has been fully rolled out.

Using the Internet of Things and cloud computing to open the bottleneck of “information isolated islands” At present, the automatic fire alarm system applied in public fire protection areas in the city is basically focused on centralized fire automatic alarm systems. Such systems are generally self-contained and self-enclosed. The sharing of resources and services between systems can only be reflected in the internal duty room of the building. When a fire breaks out, the alarm can only be made by telephone. The system cannot automatically report an alarm to the “119” fire command center, and it cannot even reflect the actual fire spot, the size of the fire, etc. on the spot. In addition, for some large-scale or unattended warehouses and woodlands, the fire command center can not grasp the fire information at the first time.

How can the situation in public areas or key units be passed to the fire department in a timely manner? The fire department of our city has built a fire information data platform, relying on the two core technologies of the Internet of things and cloud computing to change the disadvantages of each place in the past as an “island”.

“The Internet of Things, simply put, is the Internet of 'connected objects'. Its fire protection system can be roughly divided into the perception layer, network layer and application layer.” Zhao Dongping, an engineer at the Nanjing Fire Command Center, told reporters that the perception layer is already installed in the building. The fire detection equipment, alarm monitoring equipment, and automatic fire extinguishing equipment in the equipment; the application layer is the fire department and the fire protection key department; the network layer transmits the hidden danger information of the sensory layer to the application layer through wired or wireless transmission, and will be applied. Layer fire instructions are sent back to the sensory layer.

Zhao Dongping said that in this way, once a fire hazard occurs, the sensor activates an alarm device and transmits the information to the center via wireless communication or a dedicated line. The center immediately determines the location of the hidden danger; the center can directly start the fire pump at the fire site, etc. Fire extinguishing systems and personnel rescue systems, and contact 119 command center at the same time.

The high-rise building is equipped with “fire-eye” and ancient buildings are covered with digital fireproof clothing. It is understood that Zifeng Building, the tallest building in Nanjing, plans to install the first fire-fighting observation system in Jiangsu. As long as there is a fire, the system will automatically lock the fire source for real-time monitoring. Record, the fire department to grasp the fire at the first time to rescue.

“The main function of the high point of view is to timely discover the location of the fire through the high-point camera equipment, observe the fire burning and the rescue situation throughout the entire process, and guide the fire officers and soldiers of the police to reach the fire site accurately, implement the fire visual communication command, and control most of the fire in the primary stage. "The relevant person in charge of the city fire brigade said.

The responsible person said that once installed, the system will be able to monitor the area with a radius of more than 10 kilometers. At that time, all the sections of the main downtown area of ​​Nanjing and surrounding Jiangning and Pukou areas will also be covered.

In addition, the system can not only accurately grasp the fire, but also search the road between the command center and the fire site, for example, which sections of the vehicle queue is serious, which sections of traffic flow, through this remote viewing system, directing The center can also direct the driver to choose the driving route of the vehicle in the shortest possible time to shorten the time to reach the fire.

At the same time, the city also established a fire monitoring platform for ancient buildings. The 119 command center can monitor many unattended heritage buildings for 24 hours. Although many cultural relics are located in remote mountainous areas, the wireless communication module can timely transfer the operating status of the fire protection facilities of the cultural relics and potential dangers back to the center and timely deal with fire hazards.

In addition, the fire safety technology of the Internet of Things through the forest fire sensing equipment installed in the depths of the forest, if the forest fire, smoking, sensing equipment will return the signal the first time, to win valuable time for the forest fire.

Facing the complex fire situation, 3G wireless image transmission system can analyze in time and formulate the most effective rescue plan. The reporter learned that with the acceleration of the informatization construction of the fire brigade, 3G technology is widely used, and the fire brigade will realize real-time and three-dimensional transmission of disaster relief sites.

Community policing platform, to achieve full coverage of key units of information "As long as the name of the building is entered, the building contains several sprinklers, and the location of nearby fire hydrants is fully visible. The fire department can fire the rear area in advance after receiving the fire. Plan to grasp the best timing for fire fighting.” Yesterday, the Deputy Chief of the Municipal Fire Brigade Supervision and Management Branch Xue Wen introduced the situation of the community policing platform to the reporter.

The reporter saw from the information collection system of fire safety key units that the system entered more than a dozen items such as the number of building gates, whether the fire lanes were unblocked, and the types and status of fire fighting equipment.

Xue Wen said that 5191 key units in the city will complete online information entry and update on-line and realize full coverage of key units. This is also an important task for the city's firefighting informationization. In the information acquisition process of building fire control supervision, fire hazard assessment will also be conducted on the building to classify major hazards, major hidden dangers, general hidden dangers, and safety in four levels, namely, red, orange, yellow, and green. Sign mark.

"To promote the construction of remote monitoring and alarm systems for key units, by 2014, the construction rate will reach 100%. The alarm information will be transmitted to the urban fire safety remote monitoring system in real time, and the accuracy of the early warning information will be improved." "V" clearly specified in the plan.

It is understood that by taking advantage of the Youth Olympic Games, in the next two years, the city will accelerate the development of fire informationization, and the fire department will be able to organically command and dispatch the “three units into one”, remote visual image transmission, geographic information system (GIS), and GPS. Connected together to achieve real-time fire alarm linkage, remote visualization of fire scenes and positioning monitoring, simultaneous command and dispatch, and so on, so that urban security change "post-event control" for "pre-prevention" to enhance the safety of the city and the comfort of people's lives degree.
