IDM Forest Fire Prevention Intelligent Emergency Command System Solution

1.                      Background of System Construction

u       1.1 Construction Background

With the continuous development of forest protection and forestry construction, the area of forest land and forestry stock have been increasing year by year, and the task of fire prevention is becoming increasingly difficult. Forest fires are one of the important disasters in forestry. Forest fires have the characteristics of suddenness, randomness in disaster occurrence, and the ability to cause huge losses in a short period of time. Therefore, once a fire alarm occurs, firefighting measures must be taken at an extremely fast pace. Whether the firefighting is timely and the decision-making is appropriate largely depends on whether the detection of forest fire behavior is timely, whether the analysis is accurate and reasonable, and whether the decision-making measures are appropriate.

Adhere to the policy of "active prevention, early detection, early deployment, and early eradication", and achieve early detection and early resolution. It is an inevitable trend for forest fire management and development to adopt advanced technologies such as Internet, big data, Internet of Things and visualization, and use high-tech means to strengthen forest fire prevention work, make decisions and command and dispatch in the shortest time, so as to win valuable time for forest fire fighting and minimize losses.

Map data, statistical data input, editing, output, printing;

Query the distribution of cases by region, date, time, and other criteria.

3D map

Build a fully three-dimensional scene for forest management personnel to manage normally and for command personnel to intuitively command and dispatch during fires.

Visual monitoring of all time, all weather, and all terrain conditions

IoT monitoring: including seven meteorological elements in forest areas (temperature, humidity, wind direction, wind speed, air pressure, rainfall, light intensity), and monitoring of fire protection facilities in forest areas;

Video surveillance: video surveillance during key periods and areas, as well as real-time mobile video surveillance during firefighting;

Positioning and trajectory information: forest ranger inspection positioning, vehicle positioning, firefighter positioning, and fire point positioning, etc.

Real time command

Quickly locate the location of the alarm person, quickly retrieve real-time images from surrounding monitoring, automatically forward them to the nearest fire police force, generate the best response path, and dispatch drones for confirmation;

Query the geographical location and operation trajectory of attendance fire alarms, make voice/video calls with the front-end, and view real-time law enforcement videos;

Deductive demonstration: Analyze firefighting routes, annotate travel trajectories, and generate targeted firefighting plans. Based on the deduction of the fire situation on the map, real-time command and dispatch of vehicles and personnel.

4.                      Fire emergency fusion communication system

Emergency Fusion Communication

u       4.1 Problems in Forest Fire Prevention Dispatch Communication

Communication blind spot: There are many institutional departments and large organizations, generally distributed in districts, counties, and towns, which cannot effectively dispatch communication across the entire network.

Communication security and reliability: Traditional 150M/350M analog intercoms have limited frequency bands, are easily monitored, and only support voice communication. When using forest fire prevention applications, there is often a lack of 3G/4G signal from mobile phones, and communication methods are limited;

Unable to adapt to new business needs: With the rapid development of the industry, the communication tools currently used are far from meeting the needs of current business work, such as mobile approval, forest protection, patrol, communication, evidence collection, etc.

Poor portability: Staff need to be equipped with multiple devices, such as telephones and walkie talkies, which are inconvenient for daily work due to the large number of devices.

It requires integrated communication, flexible networking, stable and reliable support for various information transmission and interaction such as voice, video, and positioning.
