Firefighting skylight control system based on solar power supply and Internet of things technology and application thereof

Abstract

The invention relates to a firefighting skylight control system based on a solar power supply and an Internet of things technology. The firefighting skylight control system comprises a firefighting skylight arranged on the top of a building, a mains supply-solar power supply conversion unit, a sensor node network unit, an intelligent terminal unit and a firefighting monitoring center. The mains supply-solar power supply conversion unit comprises a battery pack which is connected with an urban power grid and a solar panel respectively and is used for supplying power to a user load through an inverter and a changeover device when the mains supply is cut off; the urban power grid directly supplies power to the user load through the changeover device. By adopting the control system, smog alarm can be made in time, and a fire smog system can be started automatically. The control system is suitable for building firefighting on public places. A scheme for taking the Internet of things technology and solar energy as backup power supplies is put forward specific to the defects of the conventional firefighting system, thereby bringing great convenience to firefighting management.

Description

technical field [0001] The invention relates to a fire-fighting skylight control system based on solar power and Internet of Things technology and its application, and belongs to the technical field of fire-fighting and smoke exhaust structure design. Background technique [0002] At the scene of a fire, there will be a lot of smoke and dust. The main cause of casualties in the fire is the toxic gas in the smoke. Statistics show that the death caused by inhalation of toxic gas in the fire is much higher than the death caused by other injuries. 85% of the people in the fire The above deaths were caused by the influence of smoke, and most of them died of coma after inhaling smoke and toxic gases. In 2000, the "12.25" catastrophic fire in Luoyang caused heavy casualties. According to the investigation after the event, the 309 people who died at the fire scene all died of suffocation due to inhalation of toxic fumes. [0003] In the densely populated areas of public buildings, ...

AI Technical Summary

Problems solved by technology

[0003] Fire and smoke exhaust systems are generally installed in densely populated areas of public buildings, but at present, it is generally impossible to know the real-time information of the fire scene in time, and the skylight of the fire and smoke exhaust system cannot be opened in a short time to discharge smoke, which makes people trapped in the accident area. Personnel inhaled smoke and toxic gas, which delayed the escape time of personnel

In addition, the mains power supply is generally used now, but when the fire is serious, the mains power will be cut off, and the fire protection system will not be able to start, which increases the safety hazard.
