Description

TECHNICAL FIELD

[0001] The present application relates to the field of fire-fighting information technology, and in particular to a fire-fighting remote control device based on Internet of Things technology. BACKGROUND

[0002] With the in-depth application of Internet of Things technology in the field of fire-fighting, more and more fire-fighting control systems have functions of remote monitoring, centralized management and data linkage, effectively improving the fire warning and disaster response capability. In modern buildings and industrial scenes, fire-fighting equipment is generally distributed in multiple functional areas, forming a distributed control structure with the help of communication links and power supply buses. Traditional fire-fighting systems mainly rely on alarm mechanisms of explicit abnormalities such as smoke, temperature or open fire. However, with the complication of system structure and diversification of abnormal performance, higher requirements are put forward for the identification and linkage disposal of hidden dangers in non-alarm states such as equipment micro-failure, communication anomaly and power disturbance.

[0003] The prior art still has obvious limitations in abnormal monitoring and remote control. First, most systems mainly rely on whether an alarm is triggered as the main judgment basis, lacking the ability to collect and analyze implicit indicators such as communication signal stability, keyboard response delay, voltage fluctuation and capacitor breakdown precursor, which easily misses early signs of failure. Second, the device state analysis mostly uses simple threshold judgment, which cannot realize trend prediction or structured analysis of fault evolution, and cannot perform consistent risk research and grouping linkage management of multiple nodes. Finally, the remote disposal strategy generally uses static plans, which do not have the ability to dynamically match response templates according to actual risk types, making it difficult to achieve flexible response and resource optimization in complex systems.
