Description

Informationized intelligent park management system

Technical Field

The invention relates to the technical field of park management, in particular to an informationized intelligent park management system.

Background

Fire safety is an extremely important aspect in modern park management. However, conventional parks typically rely on human labor for inspection work and monitoring of electrical safety of fire facilities. Such management is inefficient and often not timely and accurate in response in the event of an emergency such as a fire. In addition, conventional fire safety management methods often lack highly integrated information systems, resulting in data islanding, which affects real-time knowledge and analysis of the global status of the campus.

Currently, while some advanced fire safety management systems attempt to automate by installing simple fire sensors and cameras, these systems generally provide limited functionality, such as basic smoke or temperature detection, and do not fully assess fire risk and impact.

More advanced systems may employ data centers and some degree of sensor network, but often appear relatively weak in terms of fire simulation and prediction. Most systems lack dynamic simulation engines and are not capable of simulating the diffusion path and area of impact of a fire in real time based on status information of various sensors and devices. Furthermore, these systems also typically do not present simulation results to the manager in an intuitive, easily understood manner, thereby limiting their effectiveness in fire emergency response.

Even though some systems have more sensors and algorithm models, they often lack an integrated management platform, making it difficult to aggregate and analyze data from different departments or different locations, and thus, to achieve comprehensive, systematic campus security management.
