Nanjing Fire Protection Application Internet cloud computing technology monitoring fires

Modern Fire command Center · Newspaper Information Pictures

High-rise buildings installed "fire eye", high altitude lookout for the city fire, to achieve a radius of 10 kilometers within the range can be found in time fire; light touch the mouse, the building inside and outside at a glance, after the fire can be prepared in advance to grasp the best time to fire extinguishing ...

A few days ago, the reporter learned from the Public Security Fire Department, the city's fire information work is accelerating, innovation to combat urban disaster emergency system, the expansion of urban fire alarm remote Monitoring system, borrow green Olympic opportunity, "intelligent fire" construction has been fully rolled out.

Using the Internet of things and cloud computing to open the bottleneck of "Information Island"

At present, the fire automatic alarm system used in the public fire area of our city is mainly based on the centralized fire automatic alarming system, which is generally self-contained and self-contained, and can not realize the sharing of resources and services among the system, but only be able to respond to the room inside the building. When a fire occurs, can only use the telephone mode of alarm, the system can not automatically to the "119" Fire command center alarm, but also can not reflect the specific fire site, the size of the fire scene. In addition, for some large area or unattended warehouse, Woodland, Fire command Center can not be the first time to grasp the information.

How to make public areas or key units appear in time to the fire department? The fire Department of our city has built the fire information data platform, relying on the two core technologies of Internet of things and cloud computing, changing every place in the past is just an unfavorable situation of "island".

"The Internet of things, simply put, is the ' thing connected ' of the web, its fire system can be divided into perceptual layer, network layer and application layer. "Nanjing Fire Command center engineer Zhao Dongping told reporters that the sensing layer is the fire induction equipment, the alarm monitoring equipment and the automatic fire extinguishing equipment which has been installed in the building, the application layer is the fire department, the Fire Prevention key department, and the network layer transmits the hidden danger information of the perceptual layer to the application layer through wired or wireless transmission. and the fire command of the application layer is transmitted back to the perceptual layer.

This, Zhao Dongping says, once a fire hazard occurs, the sensor starts the alarm device, through the wireless communication or the special line will transmit the information to the center, the center immediately determines the detailed location of the hidden danger, the center can directly start fire water pump and other corresponding fire extinguishing system and personnel life-saving system, and Contact 119 command center out police

"Fire-fighting Eye", ancient buildings put on a digital fire-proof clothing

It is understood that the Nanjing tallest building purple Peak building plans to install the first fire watch system in Jiangsu, as long as there are fires, the system will automatically lock the fire source for real-time monitoring and video recording, the first time in the firefighting department to grasp the fires to rescue.

"The main role of the high lookout is to find the spot of fire through the high point camera equipment, observe the fire burning and extinguishing situation, direct the police fire officers to arrive at the fire spot accurately, carry out the fire visual Communication command, and most of the fire control in the primary stage." "The City Fire Brigade related responsible person says.

Once installed, the system will be able to monitor areas with a radius of more than 10 kilometres, the official said. At that time, the Nanjing main city and the surrounding jiangning, Pukou and other areas of some parts will also be covered.

In addition, the system not only can accurately grasp the fire, also can search between the command center and fire location, for example, which sections of the vehicle queue is serious, which sections of the car is unblocked, through this remote Observation System, command center can also in the shortest possible time to command the driver to choose the vehicle route to shorten the time to reach the fire.

At the same time, the city also set up the ancient building fire monitoring platform, 119 command Center can be a lot of unmanned cultural relics building for 24-hour monitoring. Although a lot of cultural relics are located in remote mountainous areas, but the wireless communication module can be in time to the cultural relics of the fire facilities operating conditions and dangerous hazards transmission back to the center, timely treatment of fire hazards.

In addition, the IoT fire-fighting technology by installing forest fire-awareness devices in the depths of the forest, if fire, smoke, sensory devices will return the signal at the first time, the forest fire to win valuable time.

In the face of complex fire situation, 3G wireless image transmission system can be analyzed in time, and formulate the most effective rescue plan. Reporter learned that, with the rapid pace of information construction of the fire force, 3G technology widely used, the fire force will achieve disaster relief scene real-time, stereo transmission.

Community policing platform to achieve full coverage of key unit information

"As long as the name of the building, the building installed a number of spray, the location of the nearby fire hydrant, all at a glance, the department received a fire in the rear to do a good job of fire extinguishing plan, grasp the best time to fire." Yesterday, the City Fire Brigade Supervision and Management Branch deputy long Schowen to reporters about community policing platform construction.

Reporter from the Fire Safety Key Unit information collection system, the system entered the number of building doors, fire lanes unblocked, fire equipment models and the status of more than 10 items.

Schowen said that the city's 5,191 key units will complete the information online real-time input and update, to achieve the key unit information coverage, which is also an important work of the urban fire information construction. In the process of building fire control information collection, the building will also be judged on the fire hazard, thus dividing the major hidden danger, the larger hidden danger, the general hidden danger, safety 4 grades, respectively, red, orange, yellow, green four colors mark.

"To promote the construction of the remote monitoring and alarming system of key units, 2014 years ago, the construction rate reached 100%, and the alarm information was transmitted to the city fire control remote monitoring system in real time and the accuracy of the early warning information was improved." "Our city Fire Department" Twelve-Five "plan clear request.

It is understood that the opportunity to borrow the Green Olympics, in the next two years, the city will accelerate the construction of fire information, fire Department "three in a" command and dispatch system, remote visual image transmission, geographic information system (GIS), GPS and other organically linked together to achieve real-time fire alarm, fire scene remote visualization and positioning monitoring, Synchronous command and scheduling, so that the city security changes "after the control" for "prevention beforehand" to enhance the safety of the city and the comfort of people's lives.
