Intelligent system to improve firefighting and rescue in Mongolia city

The Public Security Bureau of Ordos, a city located in China”s Inner Mongolia, has developed a Smart Fire Control Command and Dispatching System by integrating its Police Information Integrated Application Platform with GIS.

With China”s continuous social and economic development, the fire forces of the public security department are facing increasing challenges in carrying out firefighting and rescue operations. The use of information technology to effectively manage, direct, command and dispatch fire control forces has become a critical factor in the information construction of the fire control sector. Due to its capability of comprehensively analysing and managing various types of information, the geographic information system (GIS) is very much in line with the operational characteristics of fire forces. Whether in rapid response of firefighting and rescue operations, positioning of the fire alarm, path selection, queries about water sources and building situations at the corresponding fire point, or in daily fire prevention management, there is an invariable need to know the fire exits and conditions on the storage of dangerous goods and so on at crowded places. Management decisions relating to all of these can be assisted by the GIS.

The Smart Fire Control Command and Dispatching System (SFCCDS) of Ordos City has been constructed to fully realise high degree of integration between the GIS system and the Police Information Integrated Application Platform (Police Platform) and fully leverage existing data resources so as to provide fire control application services for public security sub-bureaus under the Ordos Municipal Public Security Bureau. Meanwhile, SFCCDS helps to closely rely on the strength of both the grassroots police forces and the Police Platform to realise real-time update of the specific category of geographic information data for police, and to solidify the foundation of grassroots information construction. The completion of the SFCCDS has not only improved the capacity of the fire department in assisting decision making, but also greatly enhanced the performance requirements for serving the people.

An intelligent system to improve firefighting and rescue efficiency

The SFCCDS is one of the ten applications in the police geographic information construction projects of the Ordos Municipal Public Security Bureau. The system includes the following function modules: on-map display of fire control forces, query and positioning of fire control resources, management of fire fighting vehicles, linkage movement in handling fire alarm, contingency plan management, comprehensive analysis of early warning, automatic fire alarm, fire troops path analysis, formulation of fire contingency plan, on-map click-to-call, search of surrounding fire control-related information, real-time video monitoring, analysis and processing of dangerous goods, information inquiry of the fire venue, and etc. (Figure 1, 2)

In order to enhance the rapid response capability of the firefighting personnel, measures are taken in the design of the platform such as regionalised distribution of police resources and full activation of social resources, highlighting the support provided by information technology for rapid response. To improve the efficiency of alarm detection and handling, measures are taken in the design of the platform such as the exact and fuzzy positioning of geographic coordinates of alarms so that the platform is able to draw a best path based on the positioning information and the alarm receiving unit to shorten the alarm handling time, enable rapid and effective handling of alarms and improve the efficiency of firefighting and rescue. Meanwhile, the SFCCDS has achieved such functions as positioning based on big data, alarm positioning of each level of command centers, and automatic routing based on the alarm location, etc. as well as recognition of telecommunication supplier numbers, error analysis of positioning data, fuzzy positioning, address matching and so on.

Integrating business technologies  

By combining the actual situation in Ordos City with the “digital city” concept, the SFCCDS has successfully integrated various business technologies and realised data exchange and inter-operation with other GIS.

By utilising the SOA (Service-Oriented Architecture) data services technology, an independent GIS business database is formed by extracting the on-map displayable data from both the public security database for police use and the database of other office services to achieve visualised and correlated analysis of police information. The inter-calling between Police GIS and other police information systems implemented through SOA has helped realised the integrated utilisation of SFCCDS with a variety of business and technological systems including the positioning by alarm from fixed telephone, positioning by mobile phone signal, GPS, video surveillance, etc. The Service-Oriented Architecture, where the various services are driven by various public security businesses of various types of police forces and various departments, and in return drive the technologies, renders the platform good scalability and portability so that it can automatically realise the different requirements from users with different needs. Therefore, SOA satisfactorily reflects the suitability and integrated characteristic of the platform (Figure 3).

Commanding at the firefighting and rescue sites requires not only such basic functions in traditional applications as map display and positioning, etc. but also the combination with other information systems (such as dangerous goods management information system) to allow some complex calculations on the GIS. For example, in the event of a leak of dangerous goods, such applications are needed that can carry out complex calculations based on weather conditions, hazardous materials characteristics, geographic conditions (such as population and buildings, etc.) to determine the danger zone, evacuation routes and methods and so on. In order to achieve better integration with other systems, in the near future the SFCCDS will be more open so that the information distributed in heterogeneous databases can be shared and data can be accessed so that different GIS software can be more interoperable.
